Develop Reference

Form tag is not being populated

I am trying to get reference to my form based on form id using jquery but it is failing to reference the form when I use in developer tools.Any help in much appreciated.
#model Models.ViewModel
#using (Ajax.BeginForm("TermsAndConditions", "TermsAndConditions", new AjaxOptions() { HttpMethod = "post", OnSuccess = "Save" }, new { id = "saveStatus" }))
{
<div class="row-container">
/* My UI elements */
</div>
#Html.Partial("_SubmitButtonPanel", "coverage-server-message")
}
#Html.HiddenFor(m => m.Id)
#Scripts.Render("~/bundles/datepicker")
<script type="text/javascript">
$(function () {
$('#rdate').datepicker({
defaultDate: '#Model.RDate',
showClose: true,
showClear: true,
toolbarPlacement: 'top'
});
$('#cdate').datepicker({
defaultDate: '#Model.CDate',
showClose: true,
showClear: true,
toolbarPlacement: 'top'
});
});
function CheckSave(data) {
if (data.success) {
$('#coverage-server-message').text("Successful save!");
}
else {
alert("Something went wrong!");
}
}
var formId = '#saveStatus'
</script>
Ideally I am expecting some form to be generated with my first line of code.But its not happening.
<form action="/[controller]/[method]/1?Length=12" data-ajax="true" data-ajax-method="post" data-ajax-success="CheckSaveStatusEndorsements" id="saveStatus" method="post">

Looks correct to me, you could try something like this to get a specific property.
$('#saveStatus').attr('id');
That should return the same ID that you are using as your selector.
$('#saveStatus').serialize();
This should give you all the form data as key value pairs

Jquery click doesn't work twice

I'm trying to write CRUD operations using ajax. Here some code:
These are my View classes:
//PhotoSummary
#model PhotoAlbum.WEB.Models.PhotoViewModel
<div class="well">
<h3>
<strong>#Model.Name</strong>
<span class="pull-right label label-primary">#Model.AverageRaiting.ToString("# stars")</span>
</h3>
<span class="lead">#Model.Description</span>
#Html.DialogFormLink("Update", Url.Action("UpdatePhoto", new {photoId = #Model.PhotoId}), "Update Photo", #Model.PhotoId.ToString(), Url.Action("Photo"))
</div>
//Main View
#model PhotoAlbum.WEB.Models.PhotoListViewModel
#{
ViewBag.Title = "My Photos";
}
#foreach (var p in #Model.Photos)
{
<div id=#p.PhotoId>
#Html.Action("Photo", new {photo = p})
</div>
}
The sript:
$('.dialogLink').on('click', function () {
var element = $(this);
var dialogTitle = element.attr('data-dialog-title');
var updateTargetId = '#' + element.attr('data-update-target-id');
var updateUrl = element.attr('data-update-url');
var dialogId = 'uniqueName-' + Math.floor(Math.random() * 1000)
var dialogDiv = "<div id='" + dialogId + "'></div>";
$(dialogDiv).load(this.href, function () {
$(this).dialog({
modal: true,
resizable: false,
title: dialogTitle,
close: function () { $(this).empty(); },
buttons: {
"Save": function () {
// Manually submit the form
var form = $('form', this);
$(form).submit();
},
"Cancel": function () { $(this).dialog('close'); }
}
});
$.validator.unobtrusive.parse(this);
wireUpForm(this, updateTargetId, updateUrl);
});
return false;
});});
function wireUpForm(dialog, updateTargetId, updateUrl) {
$('form', dialog).submit(function () {
if (!$(this).valid())
return false;
$.ajax({
url: this.action,
type: this.method,
data: $(this).serialize(),
success: function (result) {
if (result.success) {
$(dialog).dialog('close');
$(updateTargetId).load(updateUrl);
} else {
$(dialog).html(result);
$.validator.unobtrusive.parse(dialog);
wireUpForm(dialog, updateTargetId, updateUrl);
}
}
});
return false;
});
}
And here my Tag builder:
public static MvcHtmlString DialogFormLink(this HtmlHelper htmlHelper, string linkText, string dialogContentUrl,
string dialogTitle, string updateTargetId, string updateUrl)
{
TagBuilder builder = new TagBuilder("a");
builder.SetInnerText(linkText);
builder.Attributes.Add("href", dialogContentUrl);
builder.Attributes.Add("data-dialog-title", dialogTitle);
builder.Attributes.Add("data-update-target-id", updateTargetId);
builder.Attributes.Add("data-update-url", updateUrl);
builder.AddCssClass("dialogLink");
return new MvcHtmlString(builder.ToString());
}
So, I have major problem if the dialog was called twice without the calling page being refreshed:
it just redirects me to the action page.
The question is how to update #Html.Action without reloading the page?
Could anyone help me?

Your #foreach loop in the main view is generating a partial view for each Photo which in turn is creating a link with class="dialogLink".
Your script handles the click event of these links and replaces it with a new link with class="dialogLink". But the new link does not have a .click() handler so clicking on the new (replacement) link does not activate your script.
Instead you need to use event delegation to handle events for dynamically generated content using the .on() method (refer also here for more information on event delegation). Note also that your current use of $('.dialogLink').on('click', function () { is the equivalent of $('.dialogLink').click(function () { and is not using event delegation. It attaches a handler to elements that exist in the DOM at the time the page is loaded, not to elements that might be added in the future.
Change your html to
<div id="photos">
#foreach (var p in #Model.Photos)
{
<div class="photo">#Html.Action("Photo", new { photo = p })</div>
}
</div>
and then modify the script to
$('#photos').on('click', '.dialogLink', function() {
....
});
Side note: There is no real need to add an id=#p.PhotoId to the containing div element and you could use <div class="photo"> as per above, and then reference it by using var updateTargetId = $(this).closest('.photo'); and delete the builder.Attributes.Add("data-update-target-id", updateTargetId); line of code from your DialogFormLink() method

Get value of jquery ui dialog in code behind

I have a jquery ui dialog that has a radio button list on it. I need to call a server side method when the user clicks ok and I need to pass the selected value. I tried doing it by calling an ajax method on and passing the selected value as a parameter. This worked great (the value was passed) but I could not access a cookie from the method (got error - Request is not available in this context), which makes sense being that this is an ajax request. Here is the code:
$("#dialogReject").dialog({
autoOpen: false,
height: 300,
width: 350,
modal: true,
buttons: {
"Reject": function () {
var value = $(this).find('input:checked').val();
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "/myPage.aspx/RejectDocumentWM",
data: "{'rejectReason':'" + value + "'}",
dataType: "json",
success: function (data) {
alert('success');
},
error: function (result) { alert('error'); }
});
$(this).dialog('close');
},
Cancel: function () {
$(this).dialog("close");
}
}
});
RejectDocument():
[WebMethod]
public static void RejectDocumentWM(string rejectReason)
{
MyNamespace.myPage page = new MyNamespace.myPage();
page.RejectDocument(rejectReason);
}
protected void RejectDocument(string rejectReason)
{
batch batch = (batch)Session["Batch"];
if (client.RejectDocument(batch.GetCurrentDoc().icn, rejectReason, Request.Cookies["username"].Value)) //here is where I get the error
{
NextDocument();
}
}
I tried doing it by putting the value into a hidden field and then calling a button click which calls a server side method. My problem here was that the hidden field's value was always blank even though it set properly in the client script. Here is the code for that:
$("#dialogReject").dialog({
autoOpen: false,
height: 300,
width: 350,
modal: true,
buttons: {
"Reject": function () {
var value = $(this).find('input:checked').val();
$('[id$="hdfRejectReason"]').val(value); //this sets properly
$('[id$="btnRejectDoc"]').click();
$(this).dialog('close');
},
Cancel: function () {
$(this).dialog("close");
}
}
protected void btnRejectDoc_Click(object sender, EventArgs e)
{
batch batch = (batch)Session["Batch"];
if (client.RejectDocument(batch.GetCurrentDoc().icn, hdfRejectReason.Value, Request.Cookies["username"].Value))
//hdfRejectReason.Value is blank
{
NextDocument();
}
}
Any ideas for me? I am at my wits end.
Thanks!

First of All, is this hf is in 'popup' or in 'main page' section?
Second, in stackoverflow, we discused and set other (better?) way to set hidden field value in jQuery:
<div class="hfFoo-wrap">
<asp:HiddenField runat="server" ID="hfFoo" />
</div>
function FooBarFunction() {
var hfFoo = $('.hfFoo-wrap input[type=hidden]');
hfFoo.val('Bar');
var isBar = hfFoo.val();
}
Maybe in btnRejectDoc_Click have other 'null' or 'empty' params?
Third: I prefere FrameDialog with 'aspx' page and 'callback delegate'.
create popup as 'aspx' page
open popup from 'main page' by jQuery as jQuery.FrameDialog
close dialog from 'aspx-popup' as 'close popup' (jQuery.FrameDialog.closeDialog();)
on 'main page' catch callback delegate (with params from popup) and set hidden field there

Jquery click event not firing after getting json data

I'm working on an Asp.Net MVC3 application, using jQuery. On a specific page, the user is invited to enter the telephone number to search for a company. So, there is a result (_Result partial view) whitch I get by using json when clicking on the Search button.
On an other part, if the result is on multiple pages, when the user click the "Next button", nothing happen. Knowing that if I click on the Next button before clicking on the Search button, I have my click event fired.
The Next button is in the _Result partial view.
Here's my code HTML / Razor :
<div>
<div>
<span>Téléphone ?</span>
<input id="idTxTel" type="text" name="txTelephone"/>
<input id="idBnSearch" type="submit" value="Chercher" name="bnSearch"/>
</div>
#Html.Partial("_Result", Model)
</div>
In the _Result partial view
<div>
<span>Page N sur M</span>
<input id="bnPreviousPage" type="submit" value="Précédant" name="bnPrevious"/>
<input id="bnNextPage" type="submit" value="Suivant" name="bnNext"/>
</div>
Here's my JS code :
<script type="text/javascript">
$(document).ready(function ()
{
$("#idBnSearch").click(function ()
{
var telValue = $("#idTxTel").val();
var methodUrl = '#Url.Content("~/Search/GetReverseResult/")';
doReverseSearch(telValue, 0, methodUrl);
});
$("#bnNextPage").click(function (e)
{
alert("Next cmd");
});
});
</script>
My "doReverseSearch" method in an other JS file
function doReverseSearch(telValue, pageIdx, methodUrl)
{
$.ajax(
{
url: methodUrl,
type: 'post',
data: JSON.stringify({ Telephone: telValue, pageIndex: pageIdx }),
datatype: 'json',
contentType: 'application/json; charset=utf-8',
success: function (data) {
$('#result').replaceWith(data);
},
error: function (request, status, err) {
alert(status);
alert(err);
}
});
}
Thanks in advance

The problem is that you subscribe on the #bnNextPage click event when the document is ready but in your ajax success you replace the part of the DOM where #bnNextPage was originally.
So your click subscription is now loger active, that's way it only works if you haven't searched yet.
To make it work you need to resubscribe on the click event in the ajax success:
success: function (data) {
$('#result').replaceWith(data);
$("#bnNextPage").click(function (e)
{
alert("Next cmd");
});
},
Or as far more better solution: JQuery offers "durable" subscription with the live method. If you modify your original click code:
$("#bnNextPage").click(function (e) { alert("Next cmd"); });
to
$("#bnNextPage").live("click", function (e) { alert("Next cmd"); });
It will work without modifying your success callback.
Please note that as JQuery 1.7 the live method is deprecated and you should use the on method instead. In your case the subscription looks like the following with on:
$(document).on("click", "#bnNextPage", function (e) { alert("Next cmd"); });

ASP.Net MVC Jquery UI Autocomplete - list not showing up when I debug

I have implemented an autocomplete in my app for zip codes. I am debugging in Firebug and I see in my console that the action is performing and I get a list of zip codes in the list of results, but the actual list is not displaying when I debug.
Here's the action in my Customers controller:
//the autocomplete request sends a parameter 'term' that contains the filter
public ActionResult FindZipCode(string term)
{
string[] zipCodes = customerRepository.FindFilteredZipCodes(term);
//return raw text, one result on each line
return Content(string.Join("\n", zipCodes));
}
Here's the markup (abbreviated)
<% using (Html.BeginForm("Create", "Customers")) {%>
<input type="text" value="" name="ZipCodeID" id="ZipCodeID" />
<% } %>
and here's the order I load my scripts:
<script type="text/javascript" src="/Scripts/jquery-1.4.2.js"></script>
<script type="text/javascript" src="/Scripts/jquery.ui.core.js"></script>
<script type="text/javascript" src="/Scripts/jquery.ui.widget.js"></script>
<script type="text/javascript" src="/Scripts/jquery.ui.position.js"></script>
<script type="text/javascript" src="/Scripts/jquery.ui.autocomplete.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$("#ZipCodeID").autocomplete({ source: '<%= Url.Action("FindZipCode", "Customers") %>'});
});
</script>
Anything obvious that I'm missing? Like I say the script is grabbing the list of zip codes, they just won't display on my page when I test.
EDIT: I added an image that shows what I see in firebug - it appears that I get my zip codes back, but just won't display the dropdown.
I also updated my text box so that it's inside of the ui-widget div like so:
<div class="ui-widget">
<input type="text" name="ZipCodeID" id="ZipCodeID" />
</div>
and this is the script that I'm using:
<script type="text/javascript">
$(document).ready(function() {
$("#ZipCodeID").autocomplete('<%= Url.Action("FindZipCode", "Customers") %>');
});
</script>

I was able to get the autocomplete suggestions working using the following code:
Controller:
public JsonResult FindZipCode(string term)
{
VetClinicDataContext db = new VetClinicDataContext();
var zipCodes = from c in db.ZipCodes
where c.ZipCodeNum.ToString().StartsWith(term)
select new { value = c.ZipCodeID, label = c.ZipCodeNum};
return this.Json(zipCodes, JsonRequestBehavior.AllowGet);
}
Markup:
<script type="text/javascript">
$(document).ready(function() {
$("#ZipCodeID").autocomplete({
source: '<%= Url.Action("FindZipCode", "Customers") %>',
});
});
</script>
<div class="ui-widget"><input type="text" name="ZipCodeID" id="ZipCodeID" /></div>

I had huge problems with autocomplete few months ago when first setting it up. For instance, the simple default wireup like you do it never worked for me. I had to specify everything and also attach the result function to it.
This works 100% but it might not be suitable for you. But I hope it helps. Put both in document.ready() function.
$("#products").autocomplete('<%:Url.Action("GetProducts", "Product") %>', {
dataType: 'json',
parse: function (data) {
var rows = new Array(data.length), j;
for (j = 0; j < data.length; j++) {
rows[j] = { data: data[j], value: data[j].Title, result: data[j].Title };
}
return rows;
},
formatItem: function (row, y, n) {
return row.PrettyId + ' - ' + row.Title + ' (' + row.Price + ' €)';
},
width: 820,
minChars: 0,
max: 0,
delay: 50,
cacheLength: 10,
selectFirst: true,
selectOnly: true,
mustMatch: true,
resultsClass: "autocompleteResults"
});
$("#products").result(function (event, data, formatted) {
if (data) {
var item = $("#item_" + data.PrettyId),
edititem = $("#edititem_" + data.PrettyId),
currentQuantity;
// etc...
}
});

Try returning JSON from your controller action:
public ActionResult FindZipCode(string term)
{
string[] zipCodes = customerRepository.FindFilteredZipCodes(term);
return Json(new { suggestions = zipCodes }, JsonRequestBehavior.AllowGet);
}
Also don't forget to include the default CSS or you might not see the suggestions div appear.
