JQuery :: Couldn't Understand The Description About Success Callback Function Parameters?
Oct 22, 2011
success(data, textStatus, jqXHR)Function, Array A function to be called if the request succeeds. The function gets passed three arguments: The data returned from the server, formatted according to the dataType parameter; a string describing the status; and the jqXHR (in jQuery 1.4.x, XMLHttpRequest) object.
'success': function(html){ jQuery("#quote-of-the-day").html(html) }
success: function(data) { var out = "<ol>"; $(data).each(function(){ out+="<li>"+this.title+"</li>"; });
The above 2 ways of defining the success call back confused me.
1) According to definition, it should take 3 parameters, why here it only takes 1 parameter?
2) Why the name of parameter passed into function() can be different? Does this name matter?
I know this is a simple question with a simple answer, but I can't seem to wrap my brain around it.Sorry for the infantile nature of this post. Anyhow, I am making an AJAX call via JQuery and need the function to return a value from a calling function, like so:
today I updated my Firefox from 3.5 to 4.0b3 and it seems that the AJAX success callback is not longer fired. Firebug shows the correct response but the function is never called. Is this a Problem of the FF Beta, or is Jquery responsible for this?
And i have gone through this forum and other forums for a simple fix ... since so many have had this problem..but i have nt found anything that seems to work hence i am posting this problem
I dont know what i am doign wrong i have used debugbar and i can seethe html content that comes back i have used fiddler and i see hte html content that comes back there....the xhr stat =200 so every thing is good..yet it doesnot replace the the content $("#updateroster").html(data).
For some reason the success and error callbacks are not working at all. I'm using jquery.ajax to submit a form w/o page refresh through a php file. I have set the success & error callbacks but even when I changed the mysql password (to a incorrect one) I got the success message [code]...
I'm using getJSON to load data from the database onto a form. How can I specify the success & error callbacks? here's the code I'm using: EDIT: I managed to get the success callback by adding it below the $('fontSize')... but how can I set the error callback?

Why the following doesn't work??? It alert n times (with n=arrIDPortletNavigationDependent.length) the same element of the array: the last one.
function FadeOutAnyPortletAndAFTERalertTheirID() { for (i=0; i<arrIDPortletNavigationDependent.length; i++ ) //arrIDPortletNavigationDependent exists and contain 4 items
I have a really simple scenario which got broken after upgrading to 1.5.the defined handler for the success callback in $.ajax doen't set the data parameter - it's always undefined. This works fine in 1.4.4.
This could appear under Ajax, for example, you could have multiple objects that make a singular ajax call (say an RPC-like request) and you need to update the object that made the call during the callback with the result, but it doesn't have to be. The particular problem I'm thinking about happens to be ajax, particularly with multiple objects accessing the same ajax request (meaning I can't use a global or temporary variable).
One way that seems like it would work (just thinking about it in my head), is to create a hash, and to pass the key through the request, store the key in the response, and pick it up on the callback side. Then remove the item from the hash when done.
If slideToggle()'s parameters were expanded to include a separate callback for sliding up and sliding down. Or for backwards compatibility, perhaps include an optional boolean parameter in the callback to more easily discern between a slideUp and slideDown operation.
I don't really undertand what do $("#" + this) and $("#" + i) mean. What's the meaning of "#"? I don't understand too why the first each() function stops at "three". I think it should be return (this == "three"); instead of return (this != "three");.
I am trying to call a dynamically chosen function on success from an ajax call (later to be error and so on also)The following function works fine and passes the url to call and parameters into the makeAjaxPostCall function. successHandler is the function to call on ajax success.[code]
I need to invoke a method when a field validation is either successful or unsuccessful. I have managed to get the function to run if the field validation fails by using the following:
$('#myform').validate({ rules: { client_name: {
[code]....
But how do I invoke a method specific to a field that triggers when the field validates successfully? I need to invoke showBigGreenTick(fieldname) for the fields that are validOn another note, I find it very strange the the documentation is so poor regarding this validation. To even find out that there was a "messages" option for validate was found on another website.
Why my page is not redirecting within the if then statement.
Here is the code:
I have tried this without the if then statement and it works fine. I am not sure why my if then statement will not work within success function, am I doing something wrong?
iam either being really dumb or something is way wrong with the code. i am trying to create a fade in / fade out effect. i know there are tons of scripts out there that do this, but i like to do it myself. my script is only working in firefox at the mo (when it works il cater for other browsers). basically i can get the fade out part to work, but when i want to fade back in it does nothing. now logically id of thought that fading in would be the same as fade out but reversed.

how can i write a function that accepts a callback function?[URL].. i want myFunction to load some data via(an unordored list actually) load method end then somehow to return the wrapped elements for the callback function, exactly like load() does.
