JQuery ajax call default timeout value
(5 answers)
Closed 7 years ago.
I am using jQuery's getScript() method to load some third part js library, I am wondering whether there's a default time out value for this method. I don't really believe getScript will keep waiting until it gets a response, but I need to know how long before it quit and if that value is not ideal to me, is there a way to configure it? Maybe something like this?
$.ajaxSetup({
cache: true
});
According to jQuery documentation
This is a shorthand Ajax function, which is equivalent to:
$.ajax({
url: url,
dataType: "script",
success: success
});
So it uses the default timeout which you can override as usually you do for jQuery.ajax.

How can I get jQuery to perform a synchronous, rather than asynchronous, Ajax request?
(14 answers)
Closed 6 years ago.
I want to send to server (php) a request AJAX from an api javascript:
JS File :
var commit = new Object();
commit.id= this.id;
commit.action = this.doCommit;
commit.vrp= this.vrp;
$.post(this.ajaxURL, commit);
with this code i can send a request but in mode asynchroun. I searched on internet and I found a solution :
$.ajax({
type: 'POST',
url: this.ajaxURL,
data: commit,
async:false
});
I don't know if it is the best solution, or I can precise async:false in a $.post request, if yes , how ?.
So you do or you do not want to send the request asynchronously? The question seems to be confusing for me. But by default, $.ajax({... is always async, and $.post is just a shorthand way to write a simple post ajax request, which is also async. If you use the async:false, you are telling the javascript to not continue to execute the next line of code until the request finishes.

How to call a PHP function on the click of a button
(13 answers)
Closed 7 years ago.
I need to call a PHP function as simply as possible with OnClick event:
<button onclick="Function(5)">Call PHP function</button>
I searched for the answer, but could not find it. I think I have to use AJAX or something, but I have no experience with it. Please give me an example as simple as possible on how to call a PHP function with parameter using OnClick event.
I wouldn't use inline events on html elements - it becomes a bit of a mess. You are going to need to use Ajax to get this done. Firstly i would set up your php function in it's own page/action then set up your javascript/jquery request event like so.
<button class="call-php" value="click me"/>
$('.call-php').click(function(){
$.ajax({
async: false,
url : '/myphp.php',
type : 'get',
data : {},
success:function(data) {
// do something
},
});
});
You can call like this
<?php Function(5)?>)

how to make a jquery "$.post" request synchronous [duplicate]

Closed 8 years ago.
I have apply jQuery ajax function like this please help me how can i async false in this code
$.post(base_url+"search/questionBox/"+finalTopic+"/"+finalCountry+'/'+findSearchText+'/'+ID,function(data){
if (data != "") {
$(".lazy_loading_ul").append(data);
}
});
$.post is shorthand for $.ajax with the method set to POST. So you might as well do this:
$.ajax({
url: base_url+ 'search/questionBox/'+finalTopic+'/'+
finalCountry+'/'+findSearchText+'/'+ID
async: false,
type: 'POST'
}).done(function(data){
if(data){
$(".lazy_loading_ul").append(data);
}
});
Though I advise against async: false in the first place. As of jQuery 1.8, the async option is deprecated.
Don't use it because it defeats the purpose of using AJAX in the first place.

Run function if jQuery.ajax waiting for respond long enough
(1 answer)
Closed 8 years ago.
I know about the timeout setting for the ajax call. But what i'm wondering is, is there a way to display a message to the user if an ajax call is still processing but taking longer than x seconds.
E.g.
During an ajax call, if it takes longer than 10 secs tell the user, "call taking longer than expected"
I'd say your best bet is to use window.setTimeout for however long you want to wait for before showing your notification, and then add a window.clearTimeout line to your success callback in your $.ajax() call:
var loadingTimeout = window.setTimeout(function() {
// show your warning here
alert('Still loading :P');
}, 10000); // 10000ms = 10sec
$.ajax({
url: 'http://your/url/here',
dataType: 'json',
type: 'GET',
success: function(r) {
window.clearTimeout(loadingTimeout);
// your results logic here
}
})
Sure, just setTimeout() yourself another function that checks some global variable that gets set by the ajax completion callback. In that function, if the ajax call is still outstanding, show a message.

How can I get jQuery to perform a synchronous, rather than asynchronous, Ajax request?

I’ve been googling this and avoiding this error in my bug fix list for a long time now, but I’ve finally reached the end of the list, the last of which I have to make a function return true/false to state whether the validation has succeeded or not.
I'm using ajax to compare certain fields with those that are already in the db and by default the $.post() method does it's operations asynchronously.
I’m setting a variable inside the call onSuccess and the calling method doesn't get a response because of this, so all my js/jquery fails on pageLoad... I would prefer if I could still keep using the $.post method.
jQuery < 1.8
May I suggest that you use $.ajax() instead of $.post() as it's much more customizable.
If you are calling $.post(), e.g., like this:
$.post( url, data, success, dataType );
You could turn it into its $.ajax() equivalent:
$.ajax({
type: 'POST',
url: url,
data: data,
success: success,
dataType: dataType,
async:false
});
Please note the async:false at the end of the $.ajax() parameter object.
Here you have a full detail of the $.ajax() parameters: jQuery.ajax() – jQuery API Documentation.
jQuery >=1.8 "async:false" deprecation notice
jQuery >=1.8 won't block the UI during the http request, so we have to use a workaround to stop user interaction as long as the request is processed. For example:
use a plugin e.g. BlockUI;
manually add an overlay before calling $.ajax(), and then remove it when the AJAX .done() callback is called.
Please have a look at this answer for an example.
If you want an synchronous request set the async property to false for the request. Check out the jQuery AJAX Doc
From the Jquery docs: you specify the async option to be false to get a synchronous Ajax request. Then your callback can set some data before your mother function proceeds.
Here's what your code would look like if changed as suggested:
beforecreate: function(node,targetNode,type,to) {
jQuery.ajax({
url: url,
success: function(result) {
if(result.isOk == false)
alert(result.message);
},
async: false
});
}
this is because $.ajax is the only request type that you can set the asynchronousity for
