学习Jquery EasyUI的添加，修改，删除，查询等基本操作

初识Jquery EasyUI看了一些博主用其开发出来的项目，页面很炫，感觉功能挺强大，效果也挺不错，最近一直想系统学习一套前台控件，于是在网上找了一些参考示例。写了一些基本的增删改查功能，算是对该控件的基本入门。后续有时间继续深入学习。

在学习jquery easyui前应该先到官网下载最新版本http://www.jeasyui.com/download/index.php

先看一下运行后的页面

1、列表展示

2、新增页面

3、修改页面

把jquery easyui下载好之后，一般引用下页几个文件

  <link href="http://www.cnblogs.com/Resources/easyui/css/default.css" rel="stylesheet" type="text/css" />    <link href="http://www.cnblogs.com/Resources/easyui/js/themes/default/easyui.css" rel="stylesheet"        type="text/css" />//页面图标样式    <link href="http://www.cnblogs.com/Resources/easyui/js/themes/icon.css" rel="stylesheet" type="text/css" />    <script src="http://www.cnblogs.com/Resources/easyui/js/jquery-1.7.2.min.js" type="text/javascript"></script>//jquery easyui主要的js    <script src="http://www.cnblogs.com/Resources/easyui/js/jquery.easyui.min.js" type="text/javascript"></script>

首先是列表展示数据

 <table id="dg" title="My Users" class="easyui-datagrid" style="width: 700px; height: 250px"        url="http://www.cnblogs.com/GetJson/CreateJson.aspx" toolbar="#toolbar" pagination="true" rownumbers="true"        fitcolumns="true" singleselect="true">        <thead>            <tr>                <th field="AccountCode" width="50">                    编号                </th>                <th field="AccountName" width="50">                    卡名                </th>                <th field="AccountPwd" width="50">                    密码                </th>                <th field="CreateTime" width="50">                    创建时间                </th>                <th field="CreateName" width="50">                    创建人                </th>            </tr>        </thead>    </table>

jquery easyui是用datagrid对数据进行展示的，所以class要选择easyui-datagrid；url是本列表的一个json格式的数据来源toobar后面跟着的"#toobar"是列表的一个工具栏，本示例在列表上显示的是添加，修改，删除功能按钮对数据进行操作。pagination是否显示分页，rownumbers显示行数，分页时向后台传去两个参数，一个就是当前页数另一个就是每页显示行数；fitcolumns：自适应列宽；singleselected:单选。
工具条代码

<div id="toolbar">        <a href="javascript:void(0)" class="easyui-linkbutton" iconcls="icon-add" onclick="newuser()"            plain="true">添加</a> <a href="javascript:void(0)" class="easyui-linkbutton" iconcls="icon-edit"                onclick="edituser()" plain="true">修改</a> <a href="javascript:void(0)" class="easyui-linkbutton"                    iconcls="icon-remove" plain="true">删除</a>    </div>

数据源格式

数据源添加弹出框

?

<div id="dlg"class="easyui-dialog"style="width: 400px; height: 280px; padding: 10px 20px;"

       closed="true"buttons="#dlg-buttons">

       <divclass="ftitle">

           信息编辑

       </div>

       <form id="fm"method="post">

       <divclass="fitem">

           <label>

               编号

           </label>

           <input name="AccountCode"class="easyui-validatebox"required="true"/>

       </div>

       <divclass="fitem">

           <label>

               卡号</label>

           <input name="AccountName"class="easyui-validatebox"required="true"/>

       </div>

       <divclass="fitem">

           <label>

               密码</label>

           <input name="AccountPwd"class="easyui-validatebox"required="true"/>

       </div>

       <divclass="fitem">

           <label>

               创建时间</label>

           <input name="CreateTime"class="easyui-datebox"required="true"/>

       </div>

       <divclass="fitem">

           <label>

               创建人</label>

           <input name="CreateName"class="easyui-vlidatebox"/>

       </div>

       <input type="hidden"name="action"id="hidtype"/>

       <input type="hidden"name="ID" id="Nameid" />

       </form>

   </div>

?

<div id="dlg-buttons">

        <a href="javascript:void(0)"class="easyui-linkbutton"onclick="saveuser()"iconcls="icon-save">保存</a>

        <a href="javascript:void(0)"class="easyui-linkbutton"onclick="javascript:$('#dlg').dialog('close')"

            iconcls="icon-cancel">取消</a>

    </div>

注：class为弹出框类型；closed:当前显示状态为隐藏；buttons:弹出框的功能按钮；

对弹出的添加页面添加样式

?

<style type="text/css">

        #fm

        {

            margin: 0;

            padding: 10px 30px;

        }

        .ftitle

        {

            font-size: 14px;

            font-weight: bold;

            padding: 5px 0;

            margin-bottom: 10px;

            border-bottom: 1px solid #ccc;

        }

        .fitem

        {

            margin-bottom: 5px;

        }

        .fitem label

        {

            display: inline-block;

            width: 80px;

        }

    </style>

 js实现对数据的添加修改删除

    <script type="text/javascript">
        var url;
        var type;
        function newuser() {
            $("#dlg").dialog("open").dialog('setTitle', 'New User'); ;
            $("#fm").form("clear");
            url = "UserManage.aspx";
            document.getElementById("hidtype").value="submit";
        }
        function edituser() {
            var row = $("#dg").datagrid("getSelected");
            if (row) {
                $("#dlg").dialog("open").dialog('setTitle', 'Edit User');
                $("#fm").form("load", row);
                url = "UserManage.aspx?id=" + row.ID;
            }
        }
        function saveuser() {
            $("#fm").form("submit", {
                url: url,
                onsubmit: function () {
                    return $(this).form("validate");
                },
                success: function (result) {
                    if (result == "1") {
                        $.messager.alert("提示信息", "操作成功");
                        $("#dlg").dialog("close");
                        $("#dg").datagrid("load");
                    }
                    else {
                        $.messager.alert("提示信息", "操作失败");
                    }
                }
            });
        }
        function destroyUser() {
            var row = $('#dg').datagrid('getSelected');
            if (row) {
                $.messager.confirm('Confirm', 'Are you sure you want to destroy this user?', function (r) {
                    if (r) {
                        $.post('destroy_user.php', { id: row.id }, function (result) {
                            if (result.success) {
                                $('#dg').datagrid('reload');    // reload the user data 
                            } else {
                                $.messager.show({   // show error message 
                                    title: 'Error',
                                    msg: result.errorMsg
                                });
                            }
                        }, 'json');
                    }
                });
            }
        } 
    </script>
