In this function, I'm trying to set the value of isValid with the results of $.post:
[Code]...
Unfortunately, isValid never changes from the initial "true". I know that $.post is working correctly because #msg_code reflects the corresponding message.
I just started using jQuery, but i can't get it working. On the index.php page I want a search form, that post's to search.php. Following next, I want that the html of search.php (which will only be a table with the results), is show into the 'results' div in the index.php.
This is the code im using:
<script type="text/javascript">
/* attach a submit handler to the form */
$(document).ready(function(){
alert("Ok - 1");
[Code].....
The alert's are for debugging, but none of them show's up.
Is it possible to return Query results from a jquery $.ajax POST call?It seems as though it will only return one value. What am I missing? [code]
View 1 Replies View RelatedI am trying to use a $.post call in jQuery to check a user's credentials before submitting a form (so I can show errors without reloading the page), but I've run into a problem. I know why it is, because AJAX is not synchronous, but I just can't figure out how to do it.
In my code the script I'm making the call to returns "valid" or "invalid". If the return is "valid", I want to submit the form, if not, show an error message. Here is a simplified version:
$("#my_form").submit( function () {
some_value = "username"
$.post(script_location, {data : some_value}, function (data) {
response = data
[Code]...
This obviously does not work because code is executed quickly one after another and the variable "response" is not yet set when the execution gets to the if statement, since it is set sometime later, asynchronously.
I looked into using functions, callbacks, but nothing seems to work properly, I always run into the same issue. This is probably really simple, i just a complete dunce, please do let me know what is the standard way of doing this properly.
I am simply trying to use a global variable in javascript, but can only access the variable on the second call. 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.
[Code]....
use this kind of syntax in an open source plugin.#varableName = someMethod(); that someMethod return an object instance.Then I can access that object outside that plugin. Is this a standard javascript global variable or some jQuery feature?

SLIDER.range = $('#price-slider').slider('option','values');
SLIDER.min = SLIDER.range[0];
SLIDER.max = SLIDER.range[1];

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 want to assign value to global variable in javascript from jquery ajax function.
Here i need the value of trueFalse from success function.
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'm using this example script and need the search results to post to a another frame and not a new window.Need the results to showup in frame "test1".Or if someone can direct me: looking for a multi search drop down list in a frame environment where after submitting the string the results would show in another frame.
View 4 Replies View RelatedIn the function 'formToArray' the variable 'max' is causing a conflict in my application. The reason being that max is not explicitly defined as a var so it becomes a global variable.So IMHO:
#520 - var i,j,n,v,el;
for(i=0, max=els.length; i < max; i++) {
should be changed to
#520 - var i,j,n,v,el, max;
for(i=0, max=els.length; i < max; i++) {

If I have a global variable in one <SCRIPT>...</script>, is it available in the 2nd <SCRIPT>...</script>. I do not know if "global" means the whole document or the whole <SCRIPT>...</script> only.
View 3 Replies View RelatedI've created a site where the pages generally contain a table of
contents (site map) down the left side. When each page loads, the
first function is called. The second function populates a global var
(array) of all the links.
I try to avoid using global variables, but I am stumped how to
eliminate this one (TocLinks) because other functions need to iterate
through it. I think the answer is to create a custom object that the
other functions can access. But I need some pointers on how to
proceed.
Here's the function that the pages call initially and the 2nd function
that it calls:
I have a global variable which does not want to change :

Any clue ?
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 code my global variables first, then my window.onload function, like this code...
Why do I get the error:
"KBINPUT IS NOT DEFINED"?

Why doesn't the IF statement for UNDEFINED element catch the problem?
I have a site that calls the function welcome() and displays a prompt. The same site also has an iframe that calls the next function, add_name(), but when the pages are loaded it says that "answer" is undefined.It says on the page, where the <p id="guest"></p> is, "Welcome undefined". How do I make it so that the value of answer, which is given onLoad of the 1st page with the prompt, is displayed as text in function add_name()?
[CODE]
function welcome(){
var x = document.getElementById("body");

I'm currently coding the beginnings of a stopwatch script.
<html>
<head>
<script type="text/javascript">
var startTime;
var currentTime;
var started = 0;
function startStopwatch() {
if (started == 0) {
var startTime = new Date();
display();
alert(startTime);
}
}
function display() {
currentTime = new Date();
difference = (Number(currentTime) - Number(startTime));
document.stopwatch.display.value = difference;
setTimeout('display()',10)
}
</script>
</head>
<body>
<form name="stopwatch">
<input type="text" name="display" readonly="readonly" size="40">
<input type="button" name="start" value="Start" onclick="startStopwatch();">
<input type="button" name="stop" value="Stop">
<input type="button" name="reset" value="Reset">
</form>
</body>
</html>
The value of startTime when called from display() is undefined. I'm not sure why, as I declared the variable outside the function. The variable should be accessible by all functions, right?
Any help would be appreciated.

I wish to declare a global variable, but only if a certain condition is met. For example:
Code:
Except that now it is not global because it is contained within an if statement.
I declare multiple variables halfway down the page. The number between "mech" and "Num" is generated dynamically in the XSL. Later on I need to reference that variable in a function, but I need to build the variable name in script. How do I convert it from a string reference to a ref to the global variable?
function changePreference(pos,mt){
//mt does not reference mech2Num, I need it to.
}
changePreference(2,'my' + pos + 'Num');
var mech1Num=1|2|3|4|5|6;
var mech2Num=1|2|3|4|5|6;
var mech3Num=1|2|3|4|5|6;
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?
