我是新手，用jqueryeasyui想做了一个CRUD DataGRID，目前已经做好了界面。

后面不知道该怎么做，求大神指导我接下来该怎么做。主要是步骤。

function newUser(){ $("#dlg").dialog('open'); }

newlist

<!-- 设置table标签的属性 ID 标题 定义表格的样式为easyui-datagrid 格式
    地址定位 工具栏 排序  fitColumns：自动适应列表宽度 只能单选-->

<table id="dg" title="My Users" class="easyui-datagrid"
    style="width: 800px; height: 500px" url="get_users.php"
    toolbar="#toolbar" pagination="true" rownumbers="true"
    fitColumns="true" singleSelect="true" fit="true">

    <!-- 用thead标签创建表头 -->
    <thead>
        <tr>
            <th field="id" width="1" align="center"><input type="checkbox"></th>
            <th field="id" width="1" align="center">ID</th>
            <th field="name" width="20" align="center">姓名</th>
            <th field="age" width="5" align="center">年龄</th>
            <th field="birthday" width="5" align="center">生日</th>
            <th field="sex" width="5" align="center">性别</th>
            <th field="wages" width="5" align="center">工资</th>
            <th field="state" width="5" align="center">状态</th>
            <th field="remark" width="50" align="center">备注</th>
        </tr>
    </thead>
</table>

<!-- 给table标签toolbar属性添加div -->

<div id="toolbar">
