I have the follwoing JQuery/AJAX code:
<script>
$('.warning-dialog').click(function () {
alert($(this).data("id"));
});
$(function () {
//twitter bootstrap script
$("button#delete").click(function () {
$.ajax({
type: "GET",
url: "deleteArticleType.php",
data: { 'typeID': $('.warning-dialog').data("id") },
success: function (msg) {
$("#thanks").html(msg)
$("#form-content").modal('hide');
},
error: function () {
alert("failure");
}
});
});
});
</script>
The first function gets the data-id of a button . The second function calls a PHP page and with the method GET should get the value from the first function.
I tried the code above but it didn't work.
My question is why and how can I fix it?
If these are two separate events, disconnected in time and you want to store the value from the first click and then use it in the second click, then you will have to store it somewhere. There are several options, the simplest being a variable.
$(function () {
var lastClickId;
$('.warning-dialog').click(function () {
lastClickId = $(this).data("id");
});
//twitter bootstrap script
// FIXME: you need to add logic here for what to do if lastClickId isn't set yet
// or create a default behavior in that case
$("button#delete").click(function () {
$.ajax({
type: "GET",
url: "deleteArticleType.php",
data: { 'typeID': lastClickId },
success: function (msg) {
$("#thanks").html(msg)
$("#form-content").modal('hide');
},
error: function () {
alert("failure");
}
});
});
});
Since it looks like you are requiring the first click to happen before the second click can have something to operate on, then you should probably either modify the UI to use different types of controls or you will need to add some error handling if the user doesn't click in the right order.
Actually it should have worked using $('.warning-dialog').data("id")
If your page contains only a single class warning-dialog, you approach will be worked. It seems you're referring this class to many elements.

Im trying to show a loading div while waiting for an ajax call to complete. I have tried a couple of methods but cant seem to get anything to work consistently.
with my current code it works if i have a break point on the function that shows the div once the ajax is complete.
Fiddle
var https = 'https://www.googleapis.com/calendar/v3/calendars/';
function HideCheckShowLoading(checkId) {
$("#check_" + checkId).hide('slow', function() {
$("#loading_" + checkId).show('slow');
});
};
function HideLoadingShowCheck(checkId) {
$("#loading_" + checkId).finish().hide('slow', function() {
$("#check_" + checkId).finish().show('slow');
});
};
$(document).ready(function() {
$('#get').click(function() {
HideCheckShowLoading(1);
$.ajax({
url: https,
dataType: 'jsonp',
type: "GET",
success: function(response) {
//do something
},
error: function() {
//do something else
}
}).done(function() {
HideLoadingShowCheck(1)
});
});
$('#get2').click(function() {
HideLoadingShowCheck(1);
});
});
#check_1
{
background-color:red;
}
#loading_1
{
background-color:blue;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="check_1">Check</div>
<div hidden id="loading_1">LOADING</div>
<button id="get">Get</button>
<button id="get2">Get2</button>
What i would like to happen is,
on the click of a button we hide the check div
we show the loading div
make the ajax call
if successful do something(Reload the contents of the check div)
hide the loading div
show the check div
As said I have tried a few methods that i have found but i repeatedly get stuck with just the loading div shown
Thanks
I believe you may be slightly over-complicating things here. Something simple like this would suffice:
$('#get').click(function() {
HideCheckShowLoading();
$.ajax({
url: https,
dataType: 'jsonp',
type: "GET",
success: function (response) {
//do something
},
error: function() {
//do something else
},
complete: HideLoadingShowCheck
});
});
If you don't want the HideLoadingShowCheck routine to happen after success or error (standard behavior of complete), you can just move a function call HideLoadingShowCheck(); into your success and error blocks instead of using complete.
When you add () to a function name, it calls it immediately and returns the result. What you want to do is pass the function itself, not the result of the function - and you do that without the ().
There's no need for the $.when (assuming HideCheckShowLoading() doesn't make an ajax call, the jquery animations work differently), and $.ajax returns the promise itself, so you can update your code to:
$(document).ready(function() {
$('#get').click(function() {
HideCheckShowLoading();
$.ajax({
url: https,
dataType: 'jsonp',
type: "GET",
success: function (response) {
//do something
},
error: function() {
//do something else
}
})
//.done(HideLoadingShowCheck);
.done(function() { HideLoadingShowCheck(otherparams); })
});
});
I would change the showcheck function to add .finish() incase it's still animating from the showhide:
function HideLoadingShowCheck() {
$("#loading").finish().hide('slow',function () {
$("#check").finish().show('slow');
});
};
I want to call a function every time my update was successful. The update is working my only concern is the alert pop-up every successful update.
$.post(
{
url: 'update_question.php',
data:
{
id: id,
new_question: newText,
},
success: function()
{
that.replaceWith("<section>"+newText+"</section>");
if(text != newText)
{
popup();
}
}
});
var popup = function () {
$(document).ready (function(){
$("#myWish").click(function showAlert() {
$("#success-alert").alert();
$("#success-alert").fadeTo(2000, 500).slideUp(500, function(){
$("#success-alert").alert('close');
});
});
});
};
var popup = function () {
$("#success-alert").alert();
$("#success-alert").fadeTo(2000, 500).slideUp(500, function(){
$("#success-alert").alert('close');
});
};
On the first update, pop-up showed but it doesn't show on the 2nd update
I think it'll solve your issue
$.post(
{
url: 'update_question.php',
data:
{
id: id,
new_question: newText,
},
success: function()
{
that.replaceWith("<section>"+newText+"</section>");
if(text != newText){
popup();
}
}
});
function popup() {
$("#success-alert").alert();
$("#success-alert").fadeTo(2000, 500).slideUp(500, function(){
$("#success-alert").alert('close');
});
};
The $(document).ready jquery function waits until the DOM is loaded into your browser before it executes the javascript code contained within it's function scope {}.
So remove $(document).ready from your code.
Also note that single page applications only need to list $(document).ready once and all the listener events you setup are defined within it's body.
So you should have it listed somewhere at least once and then you define all your initial event listeners within its body.
I have an issue, do not know if it possible or not, how to check if my container is already loaded or not, because sometimes it is being loaded faster, sometimes slower and if it does not succeed in time getting an error in javaScript where gridview some functions are not recognizable(because the gridview is not loaded fast enough). Hope it is clear. Thanks for Your time.
Code:
function LoadPartial(partialUrl, container) {
$.ajax({
type: 'POST',
url: partialUrl,
success: function (returnData) {
$(container).html(returnData);
}
});
//.done(function () {
// return;
//});
}
you can use something like this.
$(".container").load(function (){
alert("Loaded :)");
});
Let me know in-case this doesn't work.
You can try using .data()
if ($('#mycontainer').data('loaded')) {
// your code
}
If you mean to find event when data received use "complete" function:
$.ajax({
type: 'POST',
url: partialUrl,
success: function (returnData) {
$(container).html(returnData);
},
complete: function() {
console.log('container filled with data');
}
});
My page makes an Ajax call which returns some HTML to embed in the page and a script to run, attaching JQuery tooltips to various elements of the embedded HTML. The HTML and script are returned as JSON objects by my Django backend, and appear OK in the page, but the Javascript doesn't seem to work when I evaluate it:
$.ajax({
type: "GET",
url: "/url/to/ajax",
data: {
"foo": bar
},
success: function (data) {
$("#my-table").html(data['html']);
// alert(data['script']); // this works: I can see the script
eval(data['script']);
},
error: function () {
$("#my-table").html('');
}
});
The script itself looks like a series of expressions such as:
$(".foobar1").tooltip({
content: "The <em>foo</em> to the <strong>bar</strong>.",
tooltipClass: "tt-ref",
show: null,
close: function (event, ui) {
ui.tooltip.hover(
function () {
$(this).stop(true).fadeTo(400, 1);
},
function () {
$(this).fadeOut("400", function () {
$(this).remove();
})
});
}
});
where foobar1 is a class in the HTML just added to the #my-table HTML.
Can anyone see where I'm going wrong here? Both jquery and jquery-ui are loaded on my page.
You don't need to eval anything, let browser execute it. For this create script element, set its content and append it to DOM:
success: function(data) {
$("#my-table").html(data.html);
$('<script>').html(data.script).appendTo('body');
},
Another, probably better option is to make script a part of the returned HTML.
You might try :
eval("data['script']");
I was working on a simple form page and I was wondering what happens if someone clicks the submit button many many times (incase my shared hosting somehow seems to be slow at that time).
Also, incase anyone wants to look at my code
$.ajax({
url: "submit.php",
type: 'POST',
data: form,
success: function (msg) {
$(".ressult").html("Thank You!");
},
error: function () {
$(".result").html("Error");
}
});
Is there a way to make it so after the user clicks it once, it won't run it again until the first click is done?
Thank you
You can use jQuery's .one() function:
(function handleSubmit() {
$('#submitBtn').one('click', function() {
var $result = $('.result');
$.ajax({
url: 'submit.php',
type: 'POST',
data: form,
success: function (msg) {
$result.html('Thank You!');
handleSubmit(); // re-bind once.
},
error: function () {
$result.html('Error');
}
}); // End ajax()
}); // End one(click)
}()); // End self-invoked handleSubmit()
*Edit: * Added recursion for multiple submissions.
Use a boolean flag
if (window.isRunning) return;
window.isRunning = true;
$.ajax({
url:"submit.php",
type: 'POST',
data: form,
success: function (msg){
$(".ressult").html("Thank You!");
},
error: function (){
$(".result").html("Error");
},
complete : function () {
window.isRunning = false;
}
});
var $button = $(this);
$button.prop('disabled', true); // disable the button
$.ajax({
url:"submit.php",
type: 'POST',
data: form,
success: function (msg){
$(".ressult").html("Thank You!");
},
error: function (){
$(".result").html("Error");
},
complete: function() {
$button.prop('disabled', false); // enable it again
}
});
Have you considered replacing your submit button with a loader image while the query executes, then re-adding it once the query is complete?
EDIT: Using the loader image is a sort of universal "I'm doing something" indicator, but disabling the button would work too!
You could disable the submit button, before the ajax call is made. And then, if required, enable it on success.
