1.fusionchart的使用方法
fusionchart的显示的两种方式的总结
方法1：通过form将xml从后台传到前台
<script type="text/javascript" src="<%=host%>/thirdparty/fusioncharts/js/FusionCharts.js"></script>
·····
<html:hidden name="scoreYhdjltjActionForm" property="bztXML" styleId="bztXML" />
·····
<td align="center">
<div id="chartdiv" align="center">教师点击量详情</div>
<script type="text/javascript">
var chartWidth = window.document.body.offsetWidth-400;
var bztchart = new FusionCharts("<%=host%>/thirdparty/fusioncharts/swf/Pie2D.swf", "ChartId", chartWidth, "360", "0", "0");
var xmlStr = $("#bztXML").val();
bztchart.addParam("wmode","Opaque");
if($.trim(xmlStr)==''||xmlStr==null){
$("#chartdiv").html("暂无数据");
}
if(bztchart!=null){
bztchart.setDataXML(xmlStr);
}
bztchart.render("chartdiv");
</script>
</td>
方法2：通过ajax方式
-------前台--------------
<script type="text/javascript">
var host = "<%=host%>";
var zygxId = "<%=zygxId%>";
var bjId ="<%=bjId_hh%>";
$(document).ready(function(){
var chartWidth = document.getElementById("chartdiv").offsetWidth;
var chart = new FusionCharts("<%=host%>/fusionCharts/MSColumn3D.swf", "myChartId", chartWidth, "300", "0", "1");
chart.addParam("wmode","Opaque");
$.ajax({
type:"post",
url: "<%=host%>/fzkt/resultStatAction.do?operFlag=statChart&zygxId="+zygxId+"&bjId="+bjId,
cache: false,
success: function(data){
var datajson = eval("["+data+"]");
var xmlStr = datajson[0].xmlStr;
var tableStr = datajson[0].tableStr;
if($.trim(xmlStr)==''||xmlStr==null){
$("#chartdiv").html("该课程下暂时没有学生答题");
return;
}
if(chart!=null){
chart.setDataXML(xmlStr);
}
chart.render("chartdiv");
document.getElementById("tableDiv").innerHTML = "";
document.getElementById("tableDiv").innerHTML = tableStr;
}
});
function tubiao(){
$.ajax({
type:"post",
url: "<%=host%>/fzkt/resultStatAction.do?operFlag=statChart&zygxId="+zygxId+"&bjId="+bjId,
cache: false,
success: function(data){
var datajson = eval("["+data+"]");
var xmlStr = datajson[0].xmlStr;
var tableStr = datajson[0].tableStr;
if($.trim(xmlStr)==''||xmlStr==null){
$("#chartdiv").html("该课程下暂时没有学生答题");
return;
}
if(chart!=null){
chart.setDataXML(xmlStr);
}
document.getElementById("tableDiv").innerHTML = "";
document.getElementById("tableDiv").innerHTML = tableStr;
}
});
}
setInterval(tubiao,5000);
});
<body style="height:100%;width:90%;overflow: auto;overflow-x:hidden;">
<div id="chartdiv" align="left" ></div>
<div id ="tableDiv" align="left"></div>
</body>
------后台-------
/**

*/
private ActionForward resultStat(ActionMapping mapping,
ResultStatActionForm resultStatActionForm,
HttpServletRequest request, HttpServletResponse response){
//ActionForward forward = mapping.findForward("statChart");
String zygxId = resultStatActionForm.getZygxId(); // 获取要统计答题结果的资源Id
String bjId = resultStatActionForm.getBjId(); //获取指定资源Id下要统计答题结果的班级Id

String resultStatTableStr = resultStatBO.getResultStat(zygxId,bjId);
response.setCharacterEncoding("gbk");
JSONObject jsonObj = new JSONObject();
jsonObj.put("xmlStr", resultStatXML);
jsonObj.put("tableStr", resultStatTableStr);
response.getOutputStream().write(jsonObj.toString().getBytes("gbk"));
} catch (Exception e) {
// 异常处理
this.exceptionOperate(request, this.getClass(), e, operFlag);
} finally {
// 资源释放
BaseResourceContainer.releaseAllResource();

// 将获取到xml数据填充到Form中
//resultStatActionForm.setResultStatXML(resultStatXML);
return null;
}

public String getJsjfchartXML(Page page,ScoreJsjfphQO jsjfphQO) throws DataAccessException, UnsupportedEncodingException {
ScorejfmxDAO jfmxDAO = ScorejfmxDAO.getJfmxDao(); //单例模式
List<ScoreJsjfphPO> jflist = jfmxDAO.getJsjfList(page,jsjfphQO); //获得教师积分list

}
}
jfXML.append("<styles>")
.append("<definition><style name='CaptionFont' type='font' size='13'/></definition>")
.append("<application><apply toObject='XAXISNAME' styles='CaptionFont' /><apply toObject='YAXISNAME' styles='CaptionFont' />")
.append("<apply toObject='CAPTION' styles='CaptionFont' /></application>")
.append("</styles>");
jfXML.append("</chart>");
return jfXML.toString();
}
=============================================================================================================================================================================
2.解决URL传中文字符出现乱码问题
--------前台--------
将中文字符加两次码：encodeURI(encodeURI(jsmc))
//积分详情
function jfxq(sfz,jsmc){
var source = $("#source").val();
var ksrq = $("#ksrq").val();
var jsrq = $("#jsrq").val();
var surl="<%=request.getContextPath()%>/score/scoreJsjfphAction.do?operFlag=jfxq&jsjfphQO.sfz="+ sfz+"&source="+source+"&jsjfphQO.ksrq="+ksrq+"&jsjfphQO.jsrq="+jsrq+"&jsjfphQO.xm="+encodeURI(encodeURI(jsmc))+"&Rnd="+Math.random();
window.showModalDialog(surl,"newwindow","dialogWidth=600px;dialogHeight=350px;scroll=no;");
}
--------后台-------
将传过来的中文字符解码一次：
String xm = form.getJsjfphQO().getXm();
xm = URLDecoder.decode(xm, "UTF-8");
form.getJsjfphQO().setXm(xm);
=============================================================================================================================================================================
3.前台计算表格中某一列数字的总和
------列1------
<td class="jsdjltd" nowrap="nowrap" align="center" height="30">
<a onclick="jsdjlxq('<bean:write name="data" property="ywdm" />','<bean:write name="data" property="ywmc" />')"><bean:write name="data" property="jsdjl" /></a>
</td>
------列2------
<td class="jzdjltd" nowrap="nowrap" align="center" height="30">
<a onclick="jzdjlxq('<bean:write name="data" property="ywdm" />','<bean:write name="data" property="ywmc" />')"><bean:write name="data" property="jzdjl" /></a>
</td>
------列3------
<td class="zdjltd" nowrap="nowrap" align="center" height="30">
<bean:write name="data" property="zdjl" />
</td>
-----计算列1的和------
<td id = "jshjdjl" nowrap="nowrap" align="center" height="30">
<script type="text/javascript">
var zjs=0;
var jszdjl=$(".jsdjltd");
jszdjl.each(function(){
zjs = zjs + parseInt( $(this).text());
});
$("#jshjdjl").text(zjs);
</script>
</td>
----·循环计算多行的和------
<td id= "hjdjl" nowrap="nowrap" align="center" height="30">
<script type="text/javascript">
var z=0;
var zdjl=$(".zdjltd");
//each的用法
zdjl.each(function(){
z = z + parseInt( $(this).text());
});
$("#hjdjl").text(z);
</script>
</td>
=============================================================================================================================================================
4.公司框架时间控件的用法
<script type="text/javascript" src='<%=host%>/thirdparty/My97DatePicker/WdatePicker.js'></script>
<td width="25%">
<param:select type="jyjxxnewTag" name="scoreYhdjltjActionForm" nullStr=""
property="yhdjltjQO.xxdm" condition="yhdjltjPO.jyjdm" styleId="xxdm" style="width:280px;height:28px;line-height:28px;"/>
</td>
<td width="50%" >
<common:text name="scoreYhdjltjActionForm" property="yhdjltjQO.ksrq"
validator="date(yyyy-mm-dd)" empty="true" styleId="ksrq" value=""
size="14" label="" maxlength="10" style="width:100px;height:28px;line-height:28px;"
onclick="WdatePicker({dateFmt:'yyyy-MM-dd',alwaysUseStartDate:true})" styleClass="Wdate"/>
至
<common:text name="scoreYhdjltjActionForm" property="yhdjltjQO.jsrq"
validator="date(yyyy-mm-dd)" empty="true" styleId="jsrq" value=""
size="14" label="" maxlength="10" style="width:100px;height:28px;line-height:28px;"
onclick="WdatePicker({dateFmt:'yyyy-MM-dd',alwaysUseStartDate:true})" styleClass="Wdate"/>
</td>
-----普通时间控件----
<input style="width:100px;height:25px;line-height:25px;" class="Wdate" type="text" onClick="WdatePicker()"><font style='display:none' color=red id='gzrqstart_empty' >*</font>
至
<input style="width:100px;height:25px;line-height:25px;" class="Wdate" type="text" onClick="WdatePicker()"><font style='display:none' color=red id='gzrqend_empty'>*</font>
=============================================================================================================================================================
5.公司框架select标签的用法
//nullStr属性让初始值为空；condition属性为查询select数据所需的条件
<td width="25%">
<param:select type="jyjxxnewTag" name="scoreYhdjltjActionForm" nullStr=""
property="yhdjltjQO.xxdm" condition="yhdjltjPO.jyjdm" styleId="xxdm" style="width:280px;height:28px;line-height:28px;"/>
</td>
------级联------
<td class="name">年级 </td>
<td class="fill">
<param:select type="xx_njTag" name="fzktzhktActionForm"
property="wjtjQO.njid" styleId="njid" nullStr=" "
condition="wjtjQO.xxdm,wjtjQO.xn,wjtjQO.xq"
label="请选择年级" onchange="chag()"/>
</td>
<td class="name" style="align:left;">班级 </td>
//notifier属性，级联年级
<td class="fill">
<param:select type="xx_bjTag" name="fzktzhktActionForm"
property="wjtjQO.bjid" styleId="bjid" nullStr=" "
label="请选择班级级" notifier="njid" />
</td>
-----普通select标签-------
<select style="width:150px;height:26px;line-height:26px;">
<option value="1">A中学</option>
<option value="2">B中学</option>
<option value="3">C中学</option>
</select>
=============================================================================================================================================================
6.判断只能输入数字的方法
------方法1------
function validate(){
var reg = new RegExp("^[0-9]*$");
var ksjfz = document.getElementById("ksjfz");
var jsjfz = document.getElementById("jsjfz");
if(!reg.test(ksjfz.value)||!reg.test(jsjfz.value)){
alert("请输入数字!");
}
if(!/^[0-9]*$/.test(ksjfz.value)||!/^[0-9]*$/.test(jsjfz.value)){
alert("请输入数字!");
}
}
------方法2--------
输入框中使用
用正则表达式：onkeyup="(this.v=function(){this.value=this.value.replace(/[^0-9-]+/,'');}).call(this)" onblur="this.v();"
<common:text name="scoreJzjfphActionForm" property="jzjfphQO.ksjfz" empty="true"
onkeyup="(this.v=function(){this.value=this.value.replace(/[^0-9-]+/,'');}).call(this)" onblur="this.v();"
validator="text(1,60)" styleId="ksjfz" size="10" maxlength="60" label="" />
============================================================================================================================================================
7.list的创建
private List<ScoreJsjfphQO> jfphbList = new ArrayList<ScoreJsjfphQO>();//积分排行list
===========================================================================================================================================================
8.sql语句，排名方式
关键代码：(Select Count(1) + 1
from (select mx.sfz, sum(mx.score) zjf
from score_jfmx mx
where mx.yxflag = '1'
and mx.zhlx = 'Z'
group by mx.sfz)
Where zjf > t.zjf) pm
示例代码：
select jzg.xm jsmc,
t.*,
(Select Count(1) + 1
from (select mx.sfz, sum(mx.score) zjf
from score_jfmx mx
where mx.yxflag = '1'
and mx.zhlx = 'Z'
group by mx.sfz)
Where zjf > t.zjf) pm
from jcsj_jzgjcxx jzg,
(select mx.sfz, sum(mx.score) zjf
from score_jfmx mx
where mx.yxflag = '1'
and mx.zhlx = 'Z'
group by mx.sfz) t
where jzg.sfz = t.sfz
and jzg.yxflag = '1'
order by t.zjf desc
=====================================================================================================================================
9.DAO层，添加方法
/**添加“操作记录”
* @param source
* @param
* @return
* @throws DataAccessException
*/
public void czjlAdd( BaseScorejfmxPO jfmxPO ) throws DataAccessException {
HibernateDataSource data = HibernateDataSource.getHibernateDataSource();
Session session = data.getSession();
StringBuffer sql = new StringBuffer();
sql.append(" insert into score_jfmx")
.append(" (ID, SFZ, YWDM, CZLX, SCORE, JFSJ, GXTIME, YXFLAG, GXR, BZ, ZHLX,YWID)")
.append(" values")
.append(" (SEQ_SCORE_PUB.NEXTVAL,")
.append(" '"+jfmxPO.getSfz()+"',")
.append(" '"+jfmxPO.getYwdm()+"',")
.append(" '"+jfmxPO.getCzlx()+"',")
.append(" (select j.score")
.append(" from score_zd_jfdy j")
.append(" where j.ywdm = '"+jfmxPO.getYwdm()+"'")
.append(" and j.czlx = '"+jfmxPO.getCzlx()+"'")
.append(" and j.yxflag = '1'),")
.append(" to_date('"+jfmxPO.getJfsjFullStr()+"',yyyy-MM-dd hh24:mi:ss),")
.append(" sysdate,")
.append(" '1',")
.append(" '"+jfmxPO.getGxr()+"',")
.append(" '',")
.append(" 'Z' ,")
.append(" '"+jfmxPO.getYwid()+"') ");
SQLQuery sqlQuery = session.createSQLQuery(sql.toString());
sqlQuery.executeUpdate();
}
==============================================================================================================================================
10.判空为0方法以及，左联方法
select zd.ywdm,
zd.ywmc,
nvl(jsdjl.jsdjl, 0) jsdjl,
nvl(jzdjl.jzdjl, 0) jzdjl,
nvl(jsdjl.jsdjl, 0) + nvl(jzdjl.jzdjl, 0) zdjl
from score_zd_yw zd,
(select mx.ywdm, count(*) jsdjl
from score_mx mx
where mx.zhlx = 'Z'
and mx.yxflag = '1'
and mx.sfz in (select distinct jzg.jzgsfz from xx_jzg jzg)
group by mx.ywdm
order by mx.ywdm) jsdjl,
(select mx.ywdm, count(*) jzdjl
from score_mx mx
where mx.zhlx = 'J'
and mx.yxflag = '1'
and mx.sfz in (select distinct gx.jzsfz
from jcsj_xsjcxx xs, jz_xs gx
where xs.sfz = gx.xssfz
and xs.yxflag = '1'
and gx.yxflag = '1')
group by mx.ywdm
order by mx.ywdm) jzdjl
where zd.ywdm = jsdjl.ywdm(+)
and zd.ywdm = jzdjl.ywdm(+)
and zd.yxflag = '1'

5.公司框架select标签的用法
//nullStr属性让初始值为空；condition属性为查询select数据所需的条件
<td width="25%">
<param:select type="jyjxxnewTag" name="scoreYhdjltjActionForm" nullStr=""
property="yhdjltjQO.xxdm" condition="yhdjltjPO.jyjdm" styleId="xxdm" style="width:280px;height:28px;line-height:28px;"/>
</td>
------级联------
<td class="name">年级 </td>
<td class="fill">
<param:select type="xx_njTag" name="fzktzhktActionForm"
property="wjtjQO.njid" styleId="njid" nullStr=" "
condition="wjtjQO.xxdm,wjtjQO.xn,wjtjQO.xq"
label="请选择年级" onchange="chag()"/>
</td>
<td class="name" style="align:left;">班级 </td>
//notifier属性，级联年级
<td class="fill">
<param:select type="xx_bjTag" name="fzktzhktActionForm"
property="wjtjQO.bjid" styleId="bjid" nullStr=" "
label="请选择班级级" notifier="njid" />
</td>
-----普通select标签-------
<select style="width:150px;height:26px;line-height:26px;">
<option value="1">A中学</option>
<option value="2">B中学</option>
<option value="3">C中学</option>
</select>
=============================================================================================================================================================
6.判断只能输入数字的方法
------方法1------
function validate(){
var reg = new RegExp("^[0-9]*$");
var ksjfz = document.getElementById("ksjfz");
var jsjfz = document.getElementById("jsjfz");
if(!reg.test(ksjfz.value)||!reg.test(jsjfz.value)){
alert("请输入数字!");
}
if(!/^[0-9]*$/.test(ksjfz.value)||!/^[0-9]*$/.test(jsjfz.value)){
alert("请输入数字!");
}
}
------方法2--------
输入框中使用
用正则表达式：onkeyup="(this.v=function(){this.value=this.value.replace(/[^0-9-]+/,'');}).call(this)" onblur="this.v();"
<common:text name="scoreJzjfphActionForm" property="jzjfphQO.ksjfz" empty="true"
onkeyup="(this.v=function(){this.value=this.value.replace(/[^0-9-]+/,'');}).call(this)" onblur="this.v();"
validator="text(1,60)" styleId="ksjfz" size="10" maxlength="60" label="" />
============================================================================================================================================================
7.list的创建
private List<ScoreJsjfphQO> jfphbList = new ArrayList<ScoreJsjfphQO>();//积分排行list
===========================================================================================================================================================
8.sql语句，排名方式
关键代码：(Select Count(1) + 1
from (select mx.sfz, sum(mx.score) zjf
from score_jfmx mx
where mx.yxflag = '1'
and mx.zhlx = 'Z'
group by mx.sfz)
Where zjf > t.zjf) pm
示例代码：
select jzg.xm jsmc,
t.*,
(Select Count(1) + 1
from (select mx.sfz, sum(mx.score) zjf
from score_jfmx mx
where mx.yxflag = '1'
and mx.zhlx = 'Z'
group by mx.sfz)
Where zjf > t.zjf) pm
from jcsj_jzgjcxx jzg,
(select mx.sfz, sum(mx.score) zjf
from score_jfmx mx
where mx.yxflag = '1'
and mx.zhlx = 'Z'
group by mx.sfz) t
where jzg.sfz = t.sfz
and jzg.yxflag = '1'
order by t.zjf desc
=====================================================================================================================================
9.DAO层，添加方法
/**添加“操作记录”
* @param source
* @param
* @return
* @throws DataAccessException
*/
public void czjlAdd( BaseScorejfmxPO jfmxPO ) throws DataAccessException {
HibernateDataSource data = HibernateDataSource.getHibernateDataSource();
Session session = data.getSession();
StringBuffer sql = new StringBuffer();
sql.append(" insert into score_jfmx")
.append(" (ID, SFZ, YWDM, CZLX, SCORE, JFSJ, GXTIME, YXFLAG, GXR, BZ, ZHLX,YWID)")
.append(" values")
.append(" (SEQ_SCORE_PUB.NEXTVAL,")
.append(" '"+jfmxPO.getSfz()+"',")
.append(" '"+jfmxPO.getYwdm()+"',")
.append(" '"+jfmxPO.getCzlx()+"',")
.append(" (select j.score")
.append(" from score_zd_jfdy j")
.append(" where j.ywdm = '"+jfmxPO.getYwdm()+"'")
.append(" and j.czlx = '"+jfmxPO.getCzlx()+"'")
.append(" and j.yxflag = '1'),")
.append(" to_date('"+jfmxPO.getJfsjFullStr()+"',yyyy-MM-dd hh24:mi:ss),")
.append(" sysdate,")
.append(" '1',")
.append(" '"+jfmxPO.getGxr()+"',")
.append(" '',")
.append(" 'Z' ,")
.append(" '"+jfmxPO.getYwid()+"') ");
SQLQuery sqlQuery = session.createSQLQuery(sql.toString());
sqlQuery.executeUpdate();
}
==============================================================================================================================================
10.判空为0方法以及，左联方法
select zd.ywdm,
zd.ywmc,
nvl(jsdjl.jsdjl, 0) jsdjl,
nvl(jzdjl.jzdjl, 0) jzdjl,
nvl(jsdjl.jsdjl, 0) + nvl(jzdjl.jzdjl, 0) zdjl
from score_zd_yw zd,
(select mx.ywdm, count(*) jsdjl
from score_mx mx
where mx.zhlx = 'Z'
and mx.yxflag = '1'
and mx.sfz in (select distinct jzg.jzgsfz from xx_jzg jzg)
group by mx.ywdm
order by mx.ywdm) jsdjl,
(select mx.ywdm, count(*) jzdjl
from score_mx mx
where mx.zhlx = 'J'
and mx.yxflag = '1'
and mx.sfz in (select distinct gx.jzsfz
from jcsj_xsjcxx xs, jz_xs gx
where xs.sfz = gx.xssfz
and xs.yxflag = '1'
and gx.yxflag = '1')
group by mx.ywdm
order by mx.ywdm) jzdjl
where zd.ywdm = jsdjl.ywdm(+)
and zd.ywdm = jzdjl.ywdm(+)
and zd.yxflag = '1'
