如何使用javascript或jquery在listview中设置hiddenfield的值

我使用以下javascript来获取我的文本框的值与autocompleteextender。如何使用javascript或jquery在listview中设置hiddenfield的值

<script type="text/javascript"> 
    function txt_lect_in_AutoCompleteExtender_itemSelected(sender, e) 
    { 
     var hdEmpId = $get('<%= hf_emp_num.ClientID %>'); 
     hdEmpId.value = e.get_value(); 
    } 
</script>

但是当我把我的文本框在我的列表视图，我无法访问控制了。

<telerik:radlistview id="RadListView1" runat="server" itemplaceholderid="EmployeesContainer" 
          cssclass="formTable cr_center" groupitemcount="2">

从萤火虫：

<div id="ctl00_ContentPlaceHolder1_RadListView1_ctrl4_Panel3" class="dataGroup">

<legend> 01-28-2011 </legend> 
<fieldset style="float: right; width: 430px;"> 
<fieldset style="float: right; width: 430px;"> 
<table class="cr_subtable" cellspacing="0" cellpadding="0"> 
<tbody> 
<tr> 
<td>المحاضرة: 4 </td> 
<td> 
<input id="ctl00_ContentPlaceHolder1_RadListView1_ctrl8_ctrl10_txt_lect_in" type="text" style="width:300px;" onkeypress="if (WebForm_TextBoxKeyHandler(event) == false) return false;" onchange="javascript:setTimeout('__doPostBack(\'ctl00$ContentPlaceHolder1$RadListView1$ctrl8$ctrl10$txt_lect_in\',\'\')', 0)" name="ctl00$ContentPlaceHolder1$RadListView1$ctrl8$ctrl10$txt_lect_in" autocomplete="off"> 
<input id="ctl00_ContentPlaceHolder1_RadListView1_ctrl8_ctrl10_hf_emp_num" type="hidden" name="ctl00$ContentPlaceHolder1$RadListView1$ctrl8$ctrl10$hf_emp_num"> 
</td> 
</tr> 
</tbody>

我想设置的隐藏字段与我的文本框选定值的值。

既然你有许多实例（每个数据行），将一些CSS类放在元素上，并通过jQuery获取它们。 domElement.control属性将为您提供IScriptControl参考

现在控件在列表视图中，您不能直接访问它。

我想要做的是创建一个公共变量，如theID，然后在listview.itemcreated事件中，使用findcontrol找到控件，然后将公共变量的值设置为其clientId，然后在您的公共变量中使用该公共变量页。

1）添加到您的文本框

<asp:TextBox id = "txt_lect_in" onkeyup = "SetContextKey()" ></asp:Textbox>

2）里面添加AutoCompleteExtender：

UseContextKey = "true"

3）jQuery的

function SetContextKey() { 

     $find('<%=txt_lect_in_AutoCompleteExtender.ClientID%>').set_contextKey($get("<%=hf_emp_num.ClientID %>").value); 


4) In Webservice Method : 

public static List<string> Get_Emp_AutoComplete(string prefixText,int count, string contextKey) 

Hope it helps,if something else please ask.
