I am using following jquery script to load another url after successful ajax request.
$(document).ready(function() {
var $loaded = $("#siteloader").data('loaded');
if($loaded == false){
$("#siteloader").load(function (){
if(ad_id != undefined){
var req_url = base_url+'ajax/saveclick/'+ad_id+'/';
var preloader = $('#preloader');
var reqloader = $('#reqloader');
$.ajax({
url: req_url,
type: 'GET',
beforeSend: function() {
$(preloader).show();
$('#adloading').remove();
},
complete: function() {
$(preloader).hide();
},
success: function(result) {
$(reqloader).html(result);
$("#siteloader").data("loaded", "true");
$("#siteloader").attr("src", base_url+'userpanel/cpa/'+ad_id+'/');
}
});
}
else{
$('#reqloader').html('<span class="text-danger">Invalid Approach!</span>');
}
});
}
});
<iframe src="remote_url" id="siteloader"></iframe>
I don't want to run ajax again after changing src on iframe and i have also tried to stop it by $("#siteloader").data("loaded", "true");
Please suggest me a good solution for this. thanks.
If you only want to execute the "load" handler once
Simply add the line
$("#siteloader").unbind('load');
In the success callback.
If you want the "load" handler to be executed on each src change, you may do something like that :
$(document).ready(function () {
$("#siteloader").load(function () {
// Move the test in the event Handler ...
var $loaded = $("#siteloader").data('loaded');
if ($loaded == false) {
if (ad_id != undefined) {
var req_url = base_url + 'ajax/saveclick/' + ad_id + '/';
var preloader = $('#preloader');
var reqloader = $('#reqloader');
$.ajax({
url: req_url,
type: 'GET',
beforeSend: function () {
$(preloader).show();
$('#adloading').remove();
},
complete: function () {
$(preloader).hide();
},
success: function (result) {
$(reqloader).html(result);
$("#siteloader").data("loaded", "true");
$("#siteloader").attr("src", base_url + 'userpanel/cpa/' + ad_id + '/');
}
});
}
else {
$('#reqloader').html('<span class="text-danger">Invalid Approach!</span>');
}
}
});
});
Maybe your ad_id variable is not well defined / changed ...

i made a function that sends data (ajax) to the database and depending on the response from the server i need to alert a message but it seems like whenvever i change the select option i get the alert message for each change(if i change the select four times when i click i get the alert four times ) , but if i remove my ajax function and replace it simply by an alert i get it once not repeating itself here is my JS
$('.select_ids').change(function () {
var id = $(this).val();
var form = $('#form_widget_ids_' + id);
var container = form.parent('.ewb_forms');
var box = container.parent('.edit_widget_box');
container.children('.selected').fadeOut(300, function () {
$(this).removeClass('selected');
form.fadeIn(300, function () {
$(this).addClass('selected');
});
});
Widget.updateSSOUrl(box);
$.ajax({
type: "POST",
url: window.location + "",
data: {'id': id}
}).done(function (msg) {
$(".red").on('click', function (evt) {
if ('done' == msg) {
evt.preventDefault();
alert('NOP');
}
})
});
});
the event that you are binding i think is wrong. For newly append items is better in your case to use
$(document).on('click', ".red", function (evt) {
})
And it must be moved outside the ajax success because now you are triggering it every time
----- Edited ---
If you want just to alert the output of the ajax you dont need the onClick event
$('.select_ids').change(function () {
var id = $(this).val();
var form = $('#form_widget_ids_' + id);
var container = form.parent('.ewb_forms');
var box = container.parent('.edit_widget_box');
container.children('.selected').fadeOut(300, function () {
$(this).removeClass('selected');
form.fadeIn(300, function () {
$(this).addClass('selected');
});
});
Widget.updateSSOUrl(box);
$.ajax({
type: "POST",
url: window.location + "",
data: {'id': id}
}).done(function (msg) {
if (msg === 'done') {
evt.preventDefault();
alert('NOP');
}
});
});
If you want to show the latest result on a button click you can store the msg on a global variable and on click of a div show that like
var globalMsg = "";
$('.select_ids').change(function () {
var id = $(this).val();
var form = $('#form_widget_ids_' + id);
var container = form.parent('.ewb_forms');
var box = container.parent('.edit_widget_box');
container.children('.selected').fadeOut(300, function () {
$(this).removeClass('selected');
form.fadeIn(300, function () {
$(this).addClass('selected');
});
});
Widget.updateSSOUrl(box);
$.ajax({
type: "POST",
url: window.location + "",
data: {'id': id}
}).done(function (msg) {
globalMsg = msg
});
});
$(".div").click(function() { alert(globalMSG); });
function Edit() {
var mode = 2; // 2 For Edit
var Fid = 0;
var viewName = 'MemberEditor';
var actionURL = '#Url.Action("setViewMode", "Member")';
$.ajax({
type: "POST",
data: {
Mode: mode,
lFeatureId: Fid,
ViewName: viewName
},
url: actionURL,
success: function (result) {
setViewMode(result);
}
});
}
this is the function where in i am calling setViewMode(result).
but somehow it is sot being called properly..
function setViewMode(data) {
for (keyVar in data) {
if (keyVar.search("Btn") != -1) {
jQuery('#' + keyVar).attr("disabled", data[keyVar]);
} else {
jQuery('#' + keyVar).prop("readonly", data[keyVar]);
}
}
}
The control isn't getting transferred to the loop. Can anyone help please?
I think you are getting back a JSON string. Use .$parseJSON(data) to get the contents stored.
I have a piece of code that does:
$('td.unique').live('click', function () {
//function logic here
});
This works fine on I click on the td of my table. All fine!
Now I would like to be able to have the same functionality programatically in certain cases without the user actually pressing click.
I have tried:
$(document).ready(function() {
$(".clearButton").click( function () {
var username = $(this).closest('tr').find('input[type="hidden"][name="uname"]').val();
var user_id = $(this).closest('tr').find('label').val();
var input = [];
input[0] = {action:'reset', id:user_id,user:username,};
$.ajax({
url: 'updateprofile.html',
data:{'user_options':JSON.stringify(input)},
type: 'POST',
dataType: 'json',
success: function (res) {
if (res.status >= 1) {
//all ok
console.log("ALL OK");
$(this).closest('tr').find('.unique').trigger('click');
$(this).closest('tr').find('td.unique').trigger('click');
$(this).closest('tr').find('td.unique').click();
}
else {
alert('failed');
}
}
});
This button is in the same row that the td.unique is
None of these work. Why? Am I doing it wrong? Is the function that I have bind in live not taken into account when I click this way?
You need to cache the $(this) inside the ajax function.
var $this = $(this);
the $(this) inside the ajax function will not refer to the element that is clicked
$(".clearButton").click(function () {
var $this = $(this);
var username = $this.closest('tr').find('input[type="hidden"][name="uname"]').val();
var user_id = $this.closest('tr').find('label').val();
var input = [];
input[0] = {
action: 'reset',
id: user_id,
user: username,
};
$.ajax({
url: 'updateprofile.html',
data: {
'user_options': JSON.stringify(input)
},
type: 'POST',
dataType: 'json',
success: function (res) {
if (res.status >= 1) {
console.log("ALL OK");
$this.closest('tr').find('.unique').trigger('click');
$this.closest('tr').find('td.unique').trigger('click');
$this.closest('tr').find('td.unique').click();
} else {
alert('failed');
}
}
});
});
i am working on project which have like unlike function look like facebook but i am getting stuck when i click multiple time at once on like button or unlike button then its work like firing and if i have 1 or 2 like and i click many time fast fast then my likes gone in -2 -1. how i solve this issue ? if when click many time always get perfect result. below my jquery script
$(document).ready(function () {
$(".like").click(function () {
var ID = $(this).attr("idl");
var REL = $(this).attr("rel");
var owner = $(this).attr("owner");
var URL = 'box_like.php';
var dataString = 'msg_id=' + ID + '&rel=' + REL + '&owner=' + owner;
$.ajax({
type: "POST",
url: URL,
data: dataString,
cache: false,
success: function (html) {
if (REL == 'Like') {
$('.blc' + ID).html('Unlike:').attr('rel', 'Unlike').attr('title', 'Unlike');
$('.spn' + ID).html(html);
} else {
$('.blc' + ID).attr('rel', 'Like').attr('title', 'Like').html('Like:');
$('.spn' + ID).html(html);
}
}
});
});
});
It is because of the async nature of ajax request.... when you click on the element continuously... the click event will get fired before the response from previous request come back and the link status is updated to next one
Case:
Assume the rel is unlike, then before the response came back again another click happens so the rel is not yet updated so you are sending another unlike request to server instead of a like request
Try below solution(Not Tested)
$(document).ready(function () {
var xhr;
$(".like").click(function () {
var ID = $(this).attr("idl");
var REL = $(this).attr("rel");
var owner = $(this).attr("owner");
var URL = 'box_like.php';
var dataString = 'msg_id=' + ID + '&rel=' + REL + '&owner=' + owner;
if (REL == 'Like') {
$('.blc' + ID).html('Unlike:').attr('rel', 'Unlike').attr('title', 'Unlike');
} else {
$('.blc' + ID).attr('rel', 'Like').attr('title', 'Like').html('Like:');
}
//abort the previous request since we don't know the response order
if (xhr) {
xhr.abort();
}
xhr = $.ajax({
type: "POST",
url: URL,
data: dataString,
cache: false
}).done(function (html) {
$('.spn' + ID).html(html);
}).always(function () {
xhr = undefined;
});
});
});
Set a variable, we'll call it stop and toggle it.
$(document).ready(function () {
var stop = false;
$(".like").click(function () {
if (!stop)
{
stop = true;
var ID = $(this).attr("idl");
var REL = $(this).attr("rel");
var owner = $(this).attr("owner");
var URL = 'box_like.php';
var dataString = 'msg_id=' + ID + '&rel=' + REL + '&owner=' + owner;
$.ajax({
type: "POST",
url: URL,
data: dataString,
cache: false,
success: function (html) {
if (REL == 'Like') {
$('.blc' + ID).html('Unlike:').attr('rel', 'Unlike').attr('title', 'Unlike');
$('.spn' + ID).html(html);
} else {
$('.blc' + ID).attr('rel', 'Like').attr('title', 'Like').html('Like:');
$('.spn' + ID).html(html);
}
}
}).always(function() { stop = false; });
}
});
});
I am using JQuery to collect latest tweets using Twitter API, but I am having some issues when calling two functions.
$(document).ready(function(){
JQTWEET.loadTweets();
});
This, is working ok, but then I want to call this function:
showHideTweets: function() {
alert("hola");
var ojeto = $(JQTWEET.appendTo).find(".item").first();
$(JQTWEET.appendTo).find(".item").first().css("display", "block");
},
Both functions are inside: jqtweet.js ...
loadTweets: function() {
var request;
// different JSON request {hash|user}
if (JQTWEET.search) {
request = {
q: JQTWEET.search,
count: JQTWEET.numTweets,
api: 'search_tweets'
}
} else {
request = {
q: JQTWEET.user,
count: JQTWEET.numTweets,
api: 'statuses_userTimeline'
}
}
$.ajax({
url: 'tweets.php',
type: 'POST',
dataType: 'json',
data: request,
success: function(data, textStatus, xhr) {
if (data.httpstatus == 200) {
if (JQTWEET.search) data = data.statuses;
var text, name, img;
try {
// append tweets into page
for (var i = 0; i < JQTWEET.numTweets; i++) {
img = '';
url = 'http://twitter.com/' + data[i].user.screen_name + '/status/' + data[i].id_str;
try {
if (data[i].entities['media']) {
img = '<img src="' + data[i].entities['media'][0].media_url + '" />';
}
} catch (e) {
//no media
}
var textoMostrar = JQTWEET.template.replace('{TEXT}', JQTWEET.ify.clean(data[i].text) ).replace('{USER}', data[i].user.screen_name).replace('{IMG}', img).replace('{URL}', url );
/*.replace('{AGO}', JQTWEET.timeAgo(data[i].created_at) ) */
//alert(JQTWEET.timeAgo(data[i].created_at));
$(JQTWEET.appendTo).append( JQTWEET.template.replace('{TEXT}', JQTWEET.ify.clean(data[i].text) )
.replace('{USER}', data[i].user.screen_name)
.replace('{NAME}', data[i].user.name)
.replace('{IMG}', img)
.replace('{PROFIMG}', data[i].user.profile_image_url)
/*.replace('{AGO}', JQTWEET.timeAgo(data[i].created_at) )*/
.replace('{URL}', url )
);
if ( (JQTWEET.numTweets - 1) == i) {
$(JQTWEET.appendTo).find(".item").last().addClass("last");
}
}
} catch (e) {
//item is less than item count
}
if (JQTWEET.useGridalicious) {
//run grid-a-licious
$(JQTWEET.appendTo).gridalicious({
gutter: 13,
width: 200,
animate: true
});
}
} else alert('no data returned');
}
});
callback();
},
showHideTweets: function() {
alert("hola");
var ojeto = $(JQTWEET.appendTo).find(".item").first();
$(JQTWEET.appendTo).find(".item").first().css("display", "block");
},
The problem is that if a call functions like this:
$(document).ready(function(){
JQTWEET.loadTweets();
JQTWEET.showHideTweets();
});
Second function executes before tweets has been loaded, so it have nothing to search in, because I can see the alert("hola") working, but Ojeto is 0.
I was trying to create some kind of callback inside loadTweets(); but I could not.
The callback isn't a bad idea.
change loadTweets to look like this:
loadTweets: function(callback) {
And call it here:
$.ajax({
...
success: function(data, textStatus, xhr) {
...
if (callback) callback();
}
});
And then in your DOM ready callback:
$(document).ready(function(){
JQTWEET.loadTweets(JQTWEET.showHideTweets);
});
Your other option (which I actually prefer, in general) is to use a deferred object:
loadTweets: function(callback) {
var def = $.Deferred();
...
$.ajax({
...
success: function(data, textStatus, xhr) {
...
def.resolve();
}
});
return def.promise();
}
...
$(document).ready(function(){
JQTWEET.loadTweets().done(JQTWEET.showHideTweets);
});
Try jQuery methods chaining:
$(document).ready(function(){
JQTWEET.loadTweets().showHideTweets();
});
