我有一个 div，我在 jquery 模态弹出窗口中显示它。我里面有一个文本框和一个按钮。单击该按钮后，我将在后面的代码上发送请求。现在，当我尝试获取文本框的值时，每次都会出现“”。下面是我的html。
<div id="divDelete" runat="server" style="display: none;">
<div>
<div>

我的jQuery文件是
$(document).ready(function () {
var $Error1 = $('[id$=divDelete]').dialog({
autoOpen: false,
resizable: false,
modal: true,
height: 'auto',
width: 580,
title: "Deactivate Account",
buttons: {
"Close": function () {
$Error1.dialog('close');
},
"Delete my account": function () {
if ($('[id$=txtPassword]').val() == '') {
$('[id$=txtPassword]').css('border', '1px solid red');
$('[id$=spPassword]').text("You can't leave this empty.");
return false;
} else {
var password = $('[id$=txtPassword]').val();
$('[id$=hdfPassword]').val(password);
alert($('[id$=hdfPassword]').val());
$('[id$=Button1]').click();
}
}
},
close: function (event, ui) {
},
open: function () {
}
});
$('[id$=btnOpenPopUp]').live('click', function (e) {
e.preventDefault();
openPopUp();
});
function openPopUp() {
$Error1.dialog('open');
}
var querystring = GetQueryStringParams('delete');
if (querystring == '1') {
openPopUp();
}
});
function GetQueryStringParams(sParam) {
var sPageURL = window.location.search.substring(1);
var sURLVariables = sPageURL.split('&');
for (var i = 0; i < sURLVariables.length; i++) {
var sParameterName = sURLVariables[i].split('=');
if (sParameterName[0] == sParam) {
return sParameterName[1];
}
}
}
代码背后的代码是
protected void Button1_Click(object sender, EventArgs e)
{
if (!string.IsNullOrEmpty(Request.QueryString["delete"]) && !string.IsNullOrEmpty(Request.QueryString["u"]))
{
try
{
Guid userId = new Guid(Convert.ToString(Request.QueryString["u"].ToString()));
objUsers.Id = userId;
objUsers.Status = "T";
objUsers.ModifiedOn = DateTime.UtcNow;
string password = txtPassword.Text;
string newass = hdfPassword.Value;
}
catch
{
Response.Write("There is some error while deleting the account.");
}
}
}
请帮助我，当我尝试通过 alert() 获取它时，它会在文本框中返回输入的值。但在它背后的代码中是""。我很困惑为什么会这样？请帮助我。
