ajax给<span>标签赋值，当时没变化
在ajax中的代码是
function LoadSelComInfo(companycode, addr_c, addr_e, labmail, txtComtel, txtemail) {
    $.ajax({
        type: "post",
        cache: false,
        dataType: "json",

        url: "handler/LoadCompanyInfo.ashx",
        data: {
            companycode: companycode,
            addr_c: addr_c,
            addr_e: addr_e
        },
        beforeSend: function (XMLHttpRequest) {
            //ShowMiniLoading2("#spLoading");
            EnableControl(); 
        },
        success: function (data, textStatus) {
            if (data) {
                $("#spComAddr").html(data.Table[0].address_1);
                $("#spComAddr_e").html(data.Table[0].address_2);

            }
        },
        complete: function (XMLHttpRequest, textStatus) {
            //StopMiniLoading2("#spLoading");
            EnableControl(); 
            window.close();
        },
        error: function () {
           // StopMiniLoading2("#spLoading");
            EnableControl(); 
            window.close();
        }
    });
}
     我用断点可以确认data的值是有的，
前台的代码是：
              <td colspan="3"  id="tdCompanyaddr" class="lv">
                        <span runat="server" id="spComAddr" ></span>  <br />
                        <span runat="server" id="spComAddr_e"></span>  <br/>
                        <input type="button" id="btncompanyaddr" value="选择" class="btn" onclick="ShowSelCompAddr()" />
