How use submit and ajax functions on click event? I need send input hidden to server using a link but no found in click event.... any solution? please help!
p.d. sorry for my english xd
$('#delete_link').click(function() {
$('#myform').submit(function() {
if ($('#codigo').val().length < 1) {$('#notice').html('Error'); return false; }
$.ajax({
type: "POST",
url: 'mantenimiento.php?action=Eliminar',
data: $(this).serialize(),
success: function(data) {
switch(data){
case 'success':
window.location.reload();
break;
default:
$('#notice').html('<p class="error">'+data+'<\/p>');
break;
}
}
});
return false;
});
});
this bit:
$('#delete_link').click(function() {
$('#myform').submit(function() {
is only binding the function to the submit event on #myform (when #delete_link is clicked), but doesn't actually trigger the event.
I think what you want is something like:
$('#myform').submit(function() {
// stuff to do when submit
});
$('#delete_link').click(function() {
$('#myform').trigger('submit');
});
You're adding a handler to the submit event which makes your AJAX request.
You need to make the AJAX request directly, without involving the submit evemt.

I am developing an MVC4 mobile app that uses several forms which are loaded into a section on the layout via ajax. I've got jQuery mobile set with Ajax turned off so I can manage the Ajax myself. Most of the forms work fine, the load and submit via ajax as they should. However, so far there is one form that refuses to fire the form submit and submit the form via ajax like the rest. First, the form is loaded when a user clicks to add a contact and this works fine:
// Handle the add contact button click
$('#btnAddNewContact').on('click', function (e) {
e.preventDefault();
// Make sure a location was selected first.
var locationID = $('#cboLocation').val();
if (locationID.length === 0) {
//$('#alertTitle').text('REQUIRED');
$('#alertMsg').html("<p>A Contact must be associated with a Location.</p><p>Please select or add a Location first.</p>");
$('#alertDialogDisplay').click();
} else {
SaveOpportunityFormState();
$.cookie('cmdLocationId', locationID, { path: '/' });
$.mobile.loading('show');
$.ajax({
url: '/Contact/Add',
type: 'GET',
cache: false,
success: function (response, status, XMLHttpRequest) {
$('section.ui-content-Override').html(response);
// Refresh the page to apply jQuery Mobile styles.
$('section.ui-content-Override').trigger('create');
// Force client side validation.
$.validator.unobtrusive.parse($('section.ui-content-Override'));
},
complete: function () {
$.cookie('cmdPreviousPage', '/Opportunity/Add', { path: '/' });
AddContactLoad();
ShowSearchHeader(false);
$.mobile.loading('hide');
},
error: function (xhr, status, error) {
// TODO - See if we need to handle errors here.
}
});
}
return false;
});
Notice that after successfully loading the form the AddContactLoad() function is fired. This works fine and here is that code:
function AddContactLoad() {
$('#contactVM_Phone').mask('(999) 999-9999? x99999');
$('#frmAddContact').on('submit', function (e) {
e.preventDefault();
if ($(this).valid()) {
$.mobile.loading('show');
$.ajax({
url: '/Contact/Add',
type: 'POST',
cache: false,
data: $(this).serialize(),
success: function (response, status, XMLHttpRequest) {
if (!response) { // Success
ReturnToAddOpportunity();
} else { // Invalid Form
$('section.ui-content-Override').html(response);
// Force jQuery Mobile to apply styles.
$('section.ui-content-Override').trigger('create');
// Force client side validation.
$.validator.unobtrusive.parse($('section.ui-content-Override'));
AddContactLoad();
$.mobile.loading('hide');
}
},
complete: function () {
},
error: function (xhr, status, error) {
// TODO - See if we need to handle errors here.
}
});
}
return false;
});
$('#btnCancel').on('click', function (e) {
e.preventDefault();
// See where add contact was called from.
var previousPage = $.cookie('cmdPreviousPage');
if (previousPage.indexOf("Detail") >= 0) {
ReturnToOpportunityDetails();
} else {
ReturnToAddOpportunity();
}
return false;
});
}
If I click the cancel button, that code is fired so I know this is working too. Here is my form code:
#using (Html.BeginForm("Add", "Contact", FormMethod.Post, new { #id = "frmAddContact" }))
{
#Html.ValidationSummary(true)
#Html.AntiForgeryToken()
-- Form Fields Here --
<div class="savecancel" >
<input type="submit" value="Save" data-mini="true", data-theme="b", data-inline="true" />
Cancel
</div>
}
As you can see the form is named frmAddContact and that is what the AddContactLoad() function is attaching the submit event to. To save my sole I cannot figure out why the form does not submit via the ajax post like every other form in the app. Am I missing some kind of initialization, I just don't know. If anyone can please help I'd really appreciate it!!
As it turns out, I had created a custom unobtrusive Ajax validator for a phone number then copied and pasted it to do the same with a zip code. Unfortunately in the process I forgot to rename a variable and thus an error was occurring in the validation script which caused the problem. In the mean time, if you're reading this, you might take a note of the code here and how to inject HTML into a page via Ajax and jQuery mobile. I've never found this in a book or on the web and it contains some very useful methodology and syntax. On the form submit the reason I'm checking for the empty response is I just return null from the controller to validate the form was valid and the save worked in which case I send them to a different HTML injection i.e. that page they originally came from. If null is not returned I inject that page with the HTML containing the original form and error markup so the user can make corrections then resubmit. I'm also calling a form load method that attaches handlers to the HTML once it's injected into the main page. Hope this helps somebody!
I would like to fire a changepage after a loadpage.
Below is the code I use.
After a submit, a database action is fired at an external site (with loadPage). That works.
Next I would like to change to another page with the guid (unique ID) variable posted.
I can't get this working.
Hope somebody can. Thanks in advance.
$(document).on('pageinit', '#page1', function(){
$('form').submit(function(){
var guid = GUID();
$.mobile.loadPage( "http://domain.com/dbaction.php?guid="+guid, {
type: "post",
data: $("form#addtegel").serialize()
});
return false;
$.mobile.changePage ($("#page2"),{ transition: "slideup"} );
});
});
$(document).on('pageinit', '#page2', function(){
DoSomething(guid);
});
First, you need to make guid a global variable. At the moment, it's local to your form submission, so it cannot be accesses outside that form submit action.
Second, instead of using loadPage() - which is jQuery Mobile's internal function called by changePage() by the way - use $.ajax() like this:
var guid;
$(document).on('pageinit', '#page1', function(){
$('form').submit(function(){
window.guid = GUID();
$.ajax({
url: "http://domain.com/dbaction.php?guid="+guid,
type: "post",
data: $("form#addtegel").serialize(),
success: function() {
$.mobile.changePage ($("#page2"), { transition: "slideup"} );
}
});
return false;
});
});
$(document).on('pageinit', '#page2', function(){
DoSomething(window.guid);
});
Also, please be aware that mixing GET and POST data is a very bad habit. I'm talking about this url: "http://domain.com/dbaction.php?guid="+guid
There should only be GET or POST data present in a single request, not both. Would it not be possible to pass guid to dbaction.php in the POST (using a hidden field in your form)?
When I add category in controller action I return JSON object:
return Json(new { categoryName = category.Name, isPrimary = isPrim ? "1" : "-1", categoryId = categoryId }, JsonRequestBehavior.AllowGet);
In JS handler function I add item on page:
...
var totalLink = "<li style='color: #bbbbbb;'>" + result.categoryName + "<a class='removeCategoryButton' href='#lnk#'>remove</a></li>";
var lnk = '#Url.Action("RemoveCategoryFromLocation", "Location", new{locationId = Model.Location.TicketId, categoryId=-1})';
totalLink = totalLink.replace('#lnk#', lnk);
totalLink = totalLink.replace('-1', result.categoryId);
$('#otherCategories').append(totalLink);
...
When I click on remove link I call the following function:
$(function () {
$('.removeCategoryButton').click(function (event) {
event.preventDefault();
$.ajax({
url: this.href,
type: 'POST',
context: this,
success: function (result) {
if(result.categoryName == 1) {
$(this).closest('li').remove();
}
}
});
return false;
});
});
But I get the following error:
This request has been blocked because sensitive information could be disclosed to third party web sites when this is used in a GET request. To allow GET requests, set JsonRequestBehavior to AllowGet.
This error happens only when I add item and want to remove it as soon after add on page. If I refresh page and click on remove link it works without problem.
Just to note when I get the error from above category is removed, so call works it just from some reason pop this error.
You seem to be adding the remove links dynamically and yet you have subscribed to the .click event handler only once when the DOM is ready. So make sure you do it in a lively manner. But since the .live() method is deprecated, depending on the jQuery version that you are using you should use either .delegate() or the .on() methods.
So with the latest version of jQuery it is recommended to use .on():
$(document).on(events, selector, data, handler);
$(document).on('click', '.removeCategoryButton', function () {
$.ajax({
url: this.href,
type: 'POST',
context: this,
success: function (result) {
if(result.categoryName == 1) {
$(this).closest('li').remove();
}
}
});
return false;
});
Notice that you no longer need to wrap this in a document.ready callback.
Friends I have a problem
We need to make a user control that has the ability to delete itself, I made it but we did not clear the mechanism for removal, it should be tied to a nice picture. Code that is attached to the frame is given below, but not
$('#delete').bind('click', function () {
alert('test');
var urlA = '<%=Url.Action("DeleteMessage","Ticket")%>';
$.ajax({
url: urlA,
type: 'POST',
data: { idMessage:$(this).parents("div:first").find("input[name='MessageID']").val(),idticket:$('#TicketID').val() },
success: function (data) {
alert(data);
}
});
});
But when I write this, but to throw me to the homepage what's wrong
$('#delete').live('click', function ()
$("#delete").live("click", function(){
//code
$(this).remove(); //delete itself
});
If your image is declared as input type="image" then it will behave like a submit button and submit your page. You should prevent the default behavior of submitting the page by adding an event.preventDefault() or equivalent to your javascript function.
I am making a jQuery ajax request in a asp.net mvc page:
$.ajax({
type: "POST",
url: "/Home/Go",
data: dataObj,
success: function (data) {
// update html here
}
}
});
This call is within a page, which has a form and other elements which submit to other url (lets say "/Home/Do"). Now after the ajax call returns, If I click on any other element the form still submits to url1 instead of url2
Note I tried adding a "return false" statement to click event handler where the ajax call is made. But even this did not help
The ajax call is made within the jQuery dialog:
$('#myDialog').dialog({ buttons:
[
{
text: 'Next',
click: function () { HandleNext(); return false; }
}
],
title: 'Dialog-Title'
});
function HandleNext()
{
$.ajax({
type: "POST",
url: "/Home/Go",
data: dataObj,
success: function (data) {
// update html here
}
}
});
return false;
}
Anybody faced a similar issue? any solutions?
return false in the click handler is mandatory for ALL ajax requests. The web browser will visit the url otherwise. In other words: The ajax request is made first and then a regular request.
No urls can automagically be replaced with other urls. You either do it in your javascript code, or in your action/view.
