Ajax :: Variable Is Undefined Outside Of Callback Function?

Mar 4, 2009

I have been trying to figure this out for a few days now and have finally come to the point where I think I got it but may just need a little push to get what I want.

Heres the situation:

I have this function that uses ajax to access a database and returns the results in the responseText. That part is working fine, I have confirmed that the responseText contains the information that I need

**************code*****************************************
//new ajax already created and assigned to the variable xmlhttp//
var response_recieved = "some data";
function get_answer(Table_Name, Field_Name, Data_Type) {

[Code]....

As evidence by my posting, this is not working correctly. The variable response_recieved is coming up undefined outside of the callback function assigned to the onreadystatechangeproperty.

Based on the information that I have gathered online from various forums, I believe this issue has to deal with a problem with closure in the callback function assigned to onreadystatechange property. I don't think it has any. Based on the fact that there is no anonymous function in that function. But my problem is that the call back function is anonymous itself... I think???

get the variable response_recieved to survive outside of this function.

Global Variable Not Valid In Callback Function?

Aug 4, 2010

I am using jQuery 1.4.2 and I am trying to carry over the global variable totaltabs into my JSON callback function. The code seems to work properly, however, in my loadJSON function after the callback function loads the data, my totaltabs variable will not increment.

Here is a peak at my code.

totalItems is loaded from another function, not relevant to my example.

Code JavaScript:
var totaltabs = 0;
$(document).ready(function(){
resize();

JQuery :: Passing A Variable From A Post Callback Function?

Oct 23, 2010

I can't seem to get a variable declared from within a post callback, so that I could manipulate my script accordingly. I have delete.php, that deletes an id from a mysql db. If it fails, I want the script to stop and display the error. The .php script echos an "ok" if everything went fine, if not - it echos the error.var abort_error; // set the error variable

$.get("delete.php", { delete: $(this).parent().parent().parent().attr('id') },
function(data){
if(data != 'ok') {

Resolved Undefined Variable In Function - Scope?

Oct 27, 2009

I'm just starting out with Javascript as a development language and this will probably be a relatively simple problem for someone to solve for me.

I am trying to access a variable (this.bodyEl.innerHTML) from within a function but get an error message indicating that it is "undefined". I know that it is a valid variable because I call it elsewhere outside of the inner function itself.

I'm sure this is just a scope issue, but I'd welcome any suggestions on how to solve it with an explanation of where I've gone wrong if you have the time.

JQuery :: How To Get Ajax Response Data To Outside Callback Function

Aug 19, 2009

I have Javascript code that looks like this:
var data1;
$.post('save_search.php', formData, function(data) {
data1 = data;
});
jsonData = eval('(' + data1 + ')');
if (jsonData.return_status.search("successful") > -1)
$('#msg_div').html("<font color=red>Search was saved</font>");
else
$('#msg_div').html("<font color=red>Search was not saved. Try saving again.</font>");
"data1" comes up as undefined in the statement
jsonData = eval('(' + data1 + ')');

Even though "data" is a perfectly correct JSON string *inside* the callback function! I can put the eval statement inside the callback function and it will form a good JSON object, like this:
jsonData = eval('(' + data + ')');
I'm simply trying to get my Ajax response data to the outside of my callback function so I can use it in other Javascript code. I've never seen an ordinary function behave this way.

JQuery :: Callback Function Required To Make Ajax Call

Jul 15, 2010

On a project I got stuck on this "problem". When you make a json (ajax) call. You also need a callback function. Which means I have to call the next $.getJSON within that callback function to read the next portion of data. In my opinion this is not very readable code...What I want is a nice and readable piece of code. Where you could just write it like this:
var data1 = $.getJSON(..);
var data2 =$.getJSON(..);
I've found a solution here: [URL] (explains my problem perfectly). But it's not compatible with the getJSON story. Is there already a possibility to do this with the jquery library?

JQuery :: Using Ajax Function To Fetch JSON Into Variable

Oct 9, 2011

I'm trying to fetch JSON contents via ajax() from a file using this code:

$.ajax({
async: false,
global: false,
url: 'pages.json',
dataType: 'json',
success: function(data){
json = data;

One problem though. The success function doesn't seem to be firing at all even though I can see the request was successfully in Firebug.

Objects, Callback Functions And Variable Scope

Nov 23, 2005

I am trying to convert some of my javascripts into a class and am
running into difficulties which i think are related to variable scope.

Basically I have a constructor function for a calendarInput class that
takes 4 parameters, the first is a reference name/number for this
input. I also have some functions for importing my PHP classes into
Javascript using AJAX (properties only. still trying to get methods
working but that's another story!). The relevant function is called
call_object_method(classname, methodname, createparams, methodparams,
post, callbackfunction). This creates an instance of the specified PHP
class using the parameters in createparams. It then calls the
specified method using the parameters in methodparams. The result is
passed back to the javascript function specified in the callbackfunction parameter (ie the value of xmlhttp.onreadystatechange is set to callbackfunction before xmlhttp.send() is called)

The function i am trying to fix is called show (x,y) which creates the
html for the calendarInput and displays it at co-ordinates x, y.

So, my code is as follows:

function calendarInput(calendarid, target, displaytarget, value)
{
this.calendarid = calendarid;
this.target = target;
this.displaytarget = displaytarget;
this.value = value;

this.show = function(x, y)
{
<!--// bunch of init and prepping code. includes creating
createparams and methodparams arrays //-->

call_object_method("cms_calendar", "getcalendarview",
createparams, methodparams, false, this.showcallback);

}

this.showcallback = function()
{
alert(this);
<!--//code to create html//-->
}

}

I know i've cut out most of the innards of this. This is because I
have already tested these functions and had the calendarInput working
outside of a class, hence am pretty sure that this is ok (plus it runs
to almost 1000 lines these days!!). My problem is that when I call the
show method, the alert on the first line of the callback function
returns the function showcallback instead of (as i was expecting) the
instance of the calendarInput object. Whilst this kinda makes sense I
can't figure out how to reference the Object instead. I have tried
'this.parent' but this returned undefined. I have tried changing the
way i reference the callback function (ie the final parameter of
call_object_method) but no joy.

Undefined Variable Error

Does anyone know why the onclick in the following popup menu gives
the error:"Val is undefined"? Does it have something to do with the
fact that it is called within the variable tablePop? Because it IS
displayed properly as part of the popup text, where it is called
outside the single quotation marks (see [***]). It is only in the
onclick that it's causing problems. Code:
