我在为Update面板中的gridview新添加/禁用验证器时遇到问题，如果我删除Update面板，则它工作正常，如果我添加Update面板，则它停止工作。我已经创建了示例页面。
Default.aspx。
<head> <script type="text/javascript" src="http://code.jquery.com/jquery-1.4.2.min.js"></script> <script type="text/javascript"> $(document).ready(function () { $('table > tbody > tr .wrapper [class*="onoff"] option:selected').each(function (index) { adjustValidators(this); }); $('[class*="onoff"] select').change(function () { adjustValidators($('option:selected', this)[0]); }); }); </script></head>

<script type="text/javascript"> function pageLoad(sender, args) { if (args.get_isPartialLoad()) { $('table > tbody > tr .wrapper [class*="onoff"] option:selected').each(function (index) { adjustValidators(this); }); } } function adjustValidators(ctrl) { var id = ctrl.parentNode.id.replace('_question', '_rfv_question').replace('ONOFF', 'testsssss') // alert(ctrl.value); if (ctrl.value == -1) { ValidatorEnable(eval(id), false) } else { ValidatorEnable(eval(id), true) } } </script>
Default.aspx.cs。
protected void Page_Load(object sender, EventArgs e)
{
MultiView1.ActiveViewIndex = (MultiView1.ActiveViewIndex == -1) ? 0 : MultiView1.ActiveViewIndex;
DataTable objData =new DataTable();
if (ViewState["data"] != null)
{
objData = (DataTable)ViewState["data"];
}
else
{
objData = new DataTable();
objData.Columns.Add("testsssss");
objData.Columns.Add("ONOFF");
objData.Columns.Add("ONOFF_selectedValue");
objData.Rows.Add(objData.NewRow());
ViewState["data"] = objData;
}
if (!IsPostBack)
{
repeatregion_RRSectionSS.DataSource = objData;
repeatregion_RRSectionSS.DataBind();
}
}
protected void btnNext_Click(object sender, EventArgs e)
{
MultiView1.ActiveViewIndex += 1;
}
protected void btnPrevious_Click(object sender, EventArgs e)
{
MultiView1.ActiveViewIndex -= 1;
}
protected void btn_Click(object sender, EventArgs e)
{
DataTable objData = (DataTable)ViewState["data"];
objData.Rows.Add(objData.NewRow());
repeatregion_RRSectionSS.DataSource = objData;
repeatregion_RRSectionSS.DataBind();
ViewState["data"] = objData;
}
[当单击添加时，然后将项添加到gridview，但是未禁用验证器。
感谢与问候Sadiq Modan
[经过一番研究和欺骗之后，我找到了解决方案：将eval中的ValidatorEnable(eval(id), false)替换为document.getElementById(id)。它对我有用。
