这是前几天的东西了,现在整理出来:

(1)工作笔记中前面提到了动态的添加javascript的东西,现在要循环把动态添加的东西取出来,这是方法:

var total = 0;

// 添加文件地址方法

function addvindicatorupdate(value1,value2,value3){

//alert(total);

var index = t1.rows.length;

//alert(index);

var oRow1=t1.insertRow(index);

var aRows=t1.rows;

var aCells1=oRow1.cells;

var oCell1_1=aRows(oRow1.rowIndex).insertCell(aCells1.length);

//oCell1_1.setAttribute("align","center");

var oCell1_2=aRows(oRow1.rowIndex).insertCell(aCells1.length);

//oCell1_2.setAttribute("align","center");

var oCell1_3=aRows(oRow1.rowIndex).insertCell(aCells1.length);

//oCell1_3.setAttribute("align","center");

var address = "address" + total;

var userId = "userId" + total;

var vindicator = "vindicator"+total;

var userName ="userName"+total;

total += 1;

//alert(total)

oCell1_1.innerHTML='';

oCell1_2.innerHTML='文件地点:';

oCell1_3.innerHTML='<input type="text" size="30" id="' + address + '" name="address" maxlenth="300" value="' + value1 + '" class="ddinput">'

+ '<input type="hidden" id="' + userId + '" name="vuserId" value="' + value2 + '">'+' '+'保管人:'

+'<input type="text" name="vindicator" id="'+vindicator+'" size="10" value="' + value3 + '">'

+ '<input type="button" name="button1" value=" 选择 " size="20" class="input" onclick="return showModalDpReturn('<%=request.getContextPath()%>/infpm/userMiddle.jsp?check=one','600','600',' + vindicator + ',' + userId + ')"/>';

}

// 添加文件地址方法

function addvindicator(){

//alert(total);

var index = t1.rows.length;

//alert(index);

var oRow1=t1.insertRow(index);

var aRows=t1.rows;

var aCells1=oRow1.cells;

var oCell1_1=aRows(oRow1.rowIndex).insertCell(aCells1.length);

//oCell1_1.setAttribute("align","center");

var oCell1_2=aRows(oRow1.rowIndex).insertCell(aCells1.length);

//oCell1_2.setAttribute("align","center");

var oCell1_3=aRows(oRow1.rowIndex).insertCell(aCells1.length);

//oCell1_3.setAttribute("align","center");

var address = "address" + total;

var userId = "userId" + total;

var vindicator = "vindicator"+total;

var userName ="userName"+total;

total += 1;

//alert(total)

oCell1_1.innerHTML='';

oCell1_2.innerHTML='文件地点:';

oCell1_3.innerHTML='<input type="text" size="30" id="' + address + '" name="address" maxlenth="300" class="ddinput">'

+ '<input type="hidden" id="' + userId + '" name="vuserId">'+' '+'保管人:'

+'<input type="text" name="vindicator" id="'+vindicator+'" size="10">'

}

//删除收件人

function deletevindicator(){

var index = t1.rows.length;

if(index>1){

t1.deleteRow(index-1);

//t1.deleteRow(index-2);

//t1.deleteRow(index-3);

total = total - 1;

}

//alert(total);

}

</script>

String value1="";

String value2="";

String value3="";

if(listaddress != null)

{

for(int i=0;i<listaddress.size();i++)

{

TfileAddress tfileAddress=(TfileAddress)listaddress.get(i);

value2 = tfileAddress.getTsysUserInf().getUserId().toString();

value1 = tfileAddress.getAddress();

value3 = tfileAddress.getTsysUserInf().getUserName().toString();

addvindicatorupdate('<%=value1%>','<%=value2%>','<%=value3%>');

</script>

}

}else{

value1="";

value2="";

value3="";

addvindicatorupdate('<%=value1%>','<%=value2%>','<%=value3%>');

</script>

}

value1 ,value2 ,value3,是添加的时候添加的数据,现在是修改页面,能保证修改.忘了把html页面部分补上了,下面是代码:

<tr>

<tr>

保管人:<input type="text" name="vindicator" id="vindicator" size="10"/>  

</td>

</tr>

</table></td>

</tr>

<tr>

</tr>

</table>

得了,顺便把判断循环动态添加的代码里面的判断不能为空的也加上吧,其实我根据需求做的是没有删除功能的,即使页面里动态的表格列出来不填也没关系,action里做了判断的,但是怕需求再次变化,只好加了删除的功能:

if(total >= 0){

document.getElementById("total").value = total;

var addresses = document.getElementsByName("address");

for(var i=0; i<addresses.length; i++)

{

var name = "address" + i;

var addresslist = document.getElementsByName(name);

for(var k=0; k<addresslist.length; k++)

{

if(addresslist[k].value=="")

{

alert("文件地址不能为空!");

return false;

}

for(var i=0; i<addresses.length; i++)

{

var name = "vindicator" + i;

var vindicatorlist = document.getElementsByName(name);

for(var j=0; j<vindicatorlist.length;j++)

{

if(vindicatorlist[j].value=="")

{

alert("保管人不能为空!");

return false;

}

恩,基本上全了,呵呵,睡觉喽!以后忘不了喽,记忆力又好使喽!
