JQuery :: Posting To A Php Page - Unable To Use A Conditional Statement With One Of The Variables?
Nov 11, 2011
I am posting two variables to a php page:
$.post('poll_receiveData.php', {question:currentSlide, vote:vote},
function(output){ ... })
}
currentSlide is set to 0. vote is set to 2. When I look at my console log, these are true. But in poll_receiveData.php, I'm unable to use a conditional statement with $vote. It's like the program doesn't know how to compare things to $vote. But a SQL statement using $question works just fine. Here's my code:

I'm trying to write a modal login script which I borrowed from the SimpleModal site. Unfortunately, I'm running into a very frustrating problem.
When the user types in a valid login/password combo, the PHP function do-login.php echos back "OK". That being said, here's a snippet of my jQuery code:
$.ajax({
type: "POST",
url: "do-login.php",
data: str,
[Code].....
The do-login.php script DOES echo back "OK"- I verified that with Firebug. But even though it echos back "OK", it goes to the 'else' clause.
I tried using return instead of echo but that didn't help either.

I am starting to learn javascript and I had a quick question. I know actionscript and java, so this my mistake here is probably context...but I cant seem to figure it out. I'm trying to figure out how to create a conditional statement based on what button a user clicks. Here's my code:
[Code]....
This doesn't seem to work. Am I referencing this.value incorrectly? If so, what's the proper way to get information about what the user clicked?

I have a table with dynamic html that contains drop down select lists
and readonly text boxes. Dynamic calculations are done on change of a
value in one of the drop down select lists.
For my first iteration the script works fine ( indicating that there
are 33 form variables ). When trying another dropdown select value, the
form elements.length is shown as 33 ( as about ) BUT the script then
crashes with a 'null value' error. I cannot access any of the form
variables - this works in all other browsers and platforms.

I found this script for a navigation fade-in/fade-out and I want to modify it so it'll only trigger the fade-in/fade-out functions of the span class is NOT set to active. Here is the javascript:
Code:
$(function() {
$("#nav ul#menu li span.active").css("opacity","1");
$("#nav ul#menu li span.active").hover("opacity","1");[code].....
It's the part of the code beneath the comment CONDITIONALS BELOW that I want to be able to only trigger it if span is not set to class .active.

I am using ajax in my site and want to implement a friend request button. When a user clicks this button their userid and the userid of the friend thwey are requesting will go into a table called notifications in my mysql database. This works fine in regular html/php with javascript disabled but not when using javascript/ajax.
Here's my code which may clarify things:-
Code:
<script type="text/javascript">
function makeRequest(friendrequestloggedinuserid, friendrequestuserid)
{
if (window.XMLHttpRequest)
[Code]....
The above code works perfect if javascript is disabled and the button is clicked as the new row is inserted into the database however if javascript is enabled the alert shows inidicating the ajax file is working but the new row is not inserted. Is this something to do with the POST process between my javascript code and my ajax_processrequests.php file?
BTW $loggedinuserid and $userid are retrieved earlier on in my code but showing how they are retrieved is irrelevant to this because I know they are present at the point of the above code.

I'm trying to code a script that will display an approximate postage price based on different combinations of variables, but the numbers I defined for each case aren't reflected in the text box. I'm using a switch statement for all the different combinations of options, which the user will choose by selecting check-boxes. (Additionally, I know that this code probably isn't a very efficient way of doing what I'm doing - how to improve it.) I've attached all the relevant parts of the code, including how I defined variables originally.
<script type="text/javascript">
function count(){
var firstclass = document.calc.firstclass.value;
var postcard = document.calc.firstclass.value;
var numpages = document.calc.numpages.value;
var nms = document.calc.nms.value;
var large = document.calc.large.value;
var numpages = parseInt(document.calc.numpages.value); .....

I've made the following script:
$(document).ready(function(){
var showHide = $.cookie('menuStatus');
alert(showHide);
/* Part that dosn´t work.
if (showHide==closed) {
$("#menu").hide();
}
*/
$(".openClose").click(
function(){
$("#menu").slideToggle("slow", function() {
if ($(this).is(':hidden')) {
//var state = "closed";
$.cookie('menuStatus', 'closed');
} else if ($(this).is(':visible')) {
//var state = "open";
$.cookie('menuStatus', 'open');
}
//alert(state);
});
});
Now this is the example: [URL]. When page loads, you get an alert, with the var showHide, which should be open or closed. Problem is the if statement. I must say it was exciting to make this little script with jQuery. Especially setting the cookie, I couldn't have done it without the jQuery plugin. As you can see I tried to set a variable first but when page reloads, the variable was reset.

I would like to be able to access the raw CSS code that has been loaded for the specific page. I'm not looking to change the code (I know how to use jQuery for CSS manipulation etc...) I just want to parse through it and extract some useful information.I considered just loading the stylesheet references in the page, then placing a request to the server for the .css file, but this feels messy even if the browser happens to have the page cached from having just requested it.Has anyone got a clue as to how one would go about this? As always, I think its best if it uses jQuery XD, however, I just really want to get this done

when reloading a page containing some jquery code based variables (which are: a variety of datepickers with set dates, and a number of form textfields containing calculated and formatted monetary values) it appears that those variables remain set. If I set a variable on the page (in a form field) then refresh the page I would like for everything to be cleared out (start with a clean slate). I work around this by setting standard values to all those fields and datepickers manually, but I would rather avoid that and clear all variables/set values, rather than assigning a value to all those fields and datepickers manually to remove previous usage traces of the page. I want the refresh to behave like a full reload. I read somewhere that loading jquery with a variable at the end of the url string would achieve that. While I know how to o that, I would rather use just jquery and make sure cache / variables are cleared each time the page is loaded. My main reason for that is I'd like users to take advantagef of google APIs (so they use a cached jQuery version, for faster page loading).
an example of the page (with manual workaround in the code) can be seen at [URL] I work around the issue by using
$(function(){//clear all numbers on refresh or new pageload.
$("input.nbr").val("0,00");
});

I have javascript which counts seperately every time 2 seperate buttons are clicked, this then outputs the amount on the same page. This works, however I am now trying to add a third value to output on the page which is the total of the clicks which i would calculate by adding the 2 attributes together. This just doesn't seem to be working though.
java
<script type="text/javascript">
var NextClick = 0;
var PrevClick = 0;
var TotalClicks = 0;

The main page of the site has this script which determines the
language settings of the OS. This works fine for IE but not for
firefox. Is there any other codes which i have to insert to make sure
Firefox would be able to load it?

function detectlang()
{
var lang=navigator.userLanguage
var langs=navigator.systemLanguage
var langb=navigator.browserLanguage
if
((langs=="ar-sa"||lang=="ar-sa"||langb=="ar-sa"))
{window.location.reload("http://www.flynas.com/ara/index.html")}
else
