JQuery :: Assign Value To Global Variable - From Ajax Function
Jan 20, 2010I want to assign value to global variable in javascript from jquery ajax function.
Here i need the value of trueFalse from success function.
I want to assign value to global variable in javascript from jquery ajax function.
Here i need the value of trueFalse from success function.
I am developing a jQuery application and I need to get a parameter from one getJSON request, then use it in another.
Here's a code example that of course is not working:
var ipAddr;
jQuery(function() {
// request IP address
$.getJSON("http://jsonip.appspot.com?callback=?", function(data) {
[Code].....
I know that getting IP address is very easy using PHP or other server side scripting language but I am bound on using HTML and jQuery only.
I was wondering if anyone knew if/how to assign an event to
a global variable?
I tried to do it and IE 7 came back with an error saying "Member not
found"
My code looked similar to the following:
var globalEvevnt;
function showPopup(event){
globalEvent = event;
alert(globalEvent.type);
setTimeout(function(){unhideDiv()}, 2000 );
}
function unhideDiv(){
alert(globalEvent.type); //Member not found error found on this
line
}
I was wondering if I had declared the globalEvent = new Object();
would that make any difference? I thought everything in JS was an
object so the event could be stored to one as well?
I have to following piece of code:
var myarray = new Array();
$.ajax({
url: 'http://distantserver.net/path/script',
dataType: "jsonp",
data: {
[Code]...
It's a cross-domain request. The first console.log() debug message prints the desired result, the second doesn't. It seems that the variable myarray has its scope limited to the success-callback. How do I get the data out of the success-callback?
I'm trying to assign IPAddress to using the code below:
function GetIP() {
$.getJSON("http://jsonip.appspot.com?callback=?",function(ipadd){
//var IPAddr;

I have a function which has a nested function in it. I need some variables in the first function to be available in the nested function. How am I supposed to declare a global variable in jquery?

View 2 Replies View RelatedI tried creating a global function to calculate the distance between 2 points.
jQuery.distance(p1, p2){
var dx = p2.x - p1.x;
var dy = p2.y - p1.y;
return Math.sqrt(dx^2 + dy^2);
};
Somewhere else within my code, I declare a new variable in order to store the value returned by the distance function.
var distance = $.distance(particle1, particle2);
However this is not working.
I have a .js file that receives a value from an html page. I'd like this
value to be a global variable that all functions in the .js file can use. I
have tried just declaring a var at the top of my .js file, but when the
value comes into the function and gets assigned to that variable, it is not
global.
I would like to store a variable then call it back later. I have a variable on line 198
www = ''+this._ad.clickUrl+'';
And on line 321 I try
document.write(www);
I've tried so many different options, just won't work. I have even tried to call document.write(window.www);

The purpose behind this is creating a form that will work with an existing database that would normally have a text area with lots of information. I am trying to turn it into a checklist that I can run from a mobile device. The global variables woudl be used to fill in a hidden text area that would then be passed on to the database upon submission. I am trying to keep the code as compact as possible.
I have a javascript that has a string variable and is hardcoded example: var text = "A,1,2,3";However, i want to read this string from a text file from the server.

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();

I can't find anything that relates to this through my searches. My application is supposed to query the server for XML that tells me which years and months are available to put into combo boxes. I want to store this xml in a global variable to access it later.

Unfortunately, isValid never changes from the initial "true". I know that $.post is working correctly because #msg_code reflects the corresponding message.
I'm trying to fetch JSON contents via ajax() from a file using this code:
// grab pages via AJAX request
sm.pages = (function() {
var json = null;
$.ajax({
async: false,
global: false,
url: 'pages.json',
dataType: 'json',
success: function(data){
json = data;
console.log(data);
}});
return json;
})();
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.
I am attempting to use the return value from a nested ajax function as the value for a variable in its parent. However, despite being able to successfully assign the variable within the nested function, it reverts back to its original value after the child function has terminated. Below is the code:

var html = $.get('templates/Template.html', function(html) {

console.log(html);
The object returned, html, have the property response, wich contain the html of page Template.html In firebug I see that the property responseText have all the html of the page, but... how can I get this value? I have try with:
