>>>>>>>>>>html

 

<form name="searchform" method="post" action="" id ="searchform">
    <td width="70" height="30"><strong>专家检索：</strong></td>
    <td height="30">
        <input type="text" name="keyword" size=20 >
        <select name="search_type" id="search_type" >
            <option value="-1">请选择搜索类型</option>
            <option value="be_name" >按专家姓名</option>
            <option value="be_intro">按专家简介</option>
        </select>
        <select name="search_dept" id="search_dept">
            <option value="-1">请选择所属科室</option>
        </select>
        <a id="submit_search">搜索</a>
    </td>
  </form>
  <table id="dg"></table>

 

>>>>>>>说明

queryParams: form2Json("searchform")  是关键，这个属性是专门用来查询的

　　为搜索按钮绑定click事件

       $("#submit_search").click(function () {
                $('#dg').datagrid({ queryParams: form2Json("searchform") });   //点击搜索
            });
