jqueryモーダルポップアップで表示しているdivがあります。その中にテキストボックスとボタンがあります。そのボタンをクリックすると、コードビハインドサイドでリクエストを送信します。これで、テキストボックスの値を取得しようとすると、毎回「」になります。以下は私のhtmlです。
<div id="divDelete" runat="server" style="display: none;">
<div>
<div>
<h2>
Are you sure you want to delete your wishisdone account?</h2>
<p>

<label class="blackLabel">
Password <span class="mandatory">*</span></label>
<p>
<asp:TextBox ID="txtPassword" CssClass="greyInputLarge" runat="server"></asp:TextBox>
<br clear="all" />
<span class="error" id="spPassword" runat="server"></span>
</p>
<label class="blackLabel">
Why are you leaving? </label>
<p>
<asp:DropDownList ID="drpReasonOfDelete" CssClass="greySelectLarge" runat="server">
<asp:ListItem Text="I have another WishIsDone account" Value="1"></asp:ListItem>
<asp:ListItem Text="I haven't registered this account" Value="2"></asp:ListItem>

<asp:ListItem Text="Technical problems" Value="4"></asp:ListItem>
<asp:ListItem Text="WishIsDone is too slow for me" Value="5"></asp:ListItem>

<p>
<asp:TextBox ID="txtReason" CssClass="greyInputLargeForMultiline" runat="server"
TextMode="MultiLine"></asp:TextBox>
</p>
<asp:HiddenField ID="hdfPassword" runat="server" />
<br clear="all" />
</div>
</div>
</div>
そして私のjqueryファイルは
$(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];
}
}
}
コードの背後にあるコードは
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.");
}
}
}
alert（）で取得しようとすると、テキストボックスに入力された値が返されます。しかし、その背後にあるコードには「」があります。なぜそれが起こっているのか完全に混乱していますか？助けてください。
