JQuery :: $.ajax With Cache: False And Async: False
Aug 8, 2010
Have an issue with using $.ajax for requests. If I set async: false it works fine, but sometimes gets cached content. If I add in cache: false then async doesn't work anymore, the next ajax request gets called before the first one finishes.

This code
$('button').click(function(){
$('body').append('<div>I am working</div>');
$.ajax({
async:false,
});
});
Doesn't display the "I am working message" until the ajax call is complete.

I am currently trying to get an action on the click of a link, and not make it follow the link, just carry everything out in jQuery. Now, if the AJAX request isn't there, it will work as supposed too, but with the AJAX request, it will follow the link, not taking any notice for the return false.

im trying to learn how jquery ajax function works by validating some form after submit is clicked.
[Code]....
the alert didnt pop until i added the registration_ok = false; right before, so im assuming it has something to do with the ajax functions's scope.... why does the ajax function not affect the registration_ok variable outside the function? and how should i solve this problem? any better way of doing it?

I have two grids, they both display buttons. One grid displays numbers, true or false and yes or no, and the other grid displays letters, true, false, yes and no.
The second grid is not displayed in the code (used css to not display second grid buttons (.answerBtns)) Now using the getButtons() function, if the user selects button "1" in first grid (the grid which you have to open using (Open Grid) link, then it should display button "A" in second grid, if user selects button "2" in first grid, then it should displays buttons "A" and "B" in second grid, if "3" then display "A", "B" and "C" and so on.
Now except using if statements and stating which buttons should be displayed and not displayed depending on the button chosen in first grid, is there a more efficent way of coding this so that the display of buttons in second grid depends on what is selected in the first grid?
If it is using an array can somebody show a sample of this in their answer. You can just do it for one example and then I should be able to use that to fill it for the other buttons.

I've been trying to make my very ajaxy site more SEO friendly, lots of the returned actions from ajax can be retrieved as a full page, so it's just a matter of exposing the links. Up until now I've had 'span' tags which I have now changed to 'a href' so that the search engines will follow them. I've added the following code so that if the event should send an ajax request, it does that, or if it should go get the full page, it does that.
<code>
jQuery('a.mixContent').livequery('click',function(){
var vtid=jQuery(this)..parent('div.controller').parent('li').attr
('id');
alert(eventid);
if(eventid!=null){
clicked(getSelected, eventid);
} else {
[Code]...

When I create a new div and insert it with .append(ndiv) to an existing div ndiv.width() returns the width of the parent div instead of the actual value. This is the same in FF4 and IE9 so I suppose this is a regular behavior and I just don't realize how to deal with it.

This works fine in Firefox, but Internet Explorer ignores the return false and just follows the link.

i'm unable to do this with jQuery 1.6 but it works fine with jQuery 1.5.2 :
$('#comment-content')
.delegate('#chkb-status-review,#chkb-status-validate','change',function(){
$('#chkb-status-review,#chkb-status-validate').attr('checked',false);
$(this).attr('checked',true);
})
No error, just not working. Maybe i'm doing something wrong

I have the following code
Code:
$('a').live( 'click', doIt() ) ;
...
function doIt() { return false }
However, the 'return false' does nothing. If I click a link the event is not stopped and the page it points to is loaded!
So, what could I do, given the above code, to stop the click event ?
UPDATE: I inspected jQuery object and changed doIt to
Code:
function doIt() {
$.Event.preventDefault();
$.Event.stopPropogation() ;
}
Does not produce errors, but didn't stop the event, but I feel I'm getting closer

Do you have to use the onClick attrib to have
return false
work?
i.e. is it possible to do
<a href="javascript:somefunct();return false;">
and have the page not reload with 'false' or the browser not complain about
illegal use?

I have a page built with asp.net that includes some "imagebutton"s within a form. These render as input tags with the type set to image. I ahve the onclick attribute set to run a custom javascript function and return false.This has worked fine for the few months the code has been in place and then just recently (within the last few days) it has stopped working for a single network user. They click on the link and instead of the function executing (and the AJAX loading details into the page) the form submits. This makes me think that the "return false" simply isn't executing. The user says that they haven't changed any settings or anything that may cause this issue...
The browser being used throughout the company is IE8 under Windows XP. I have checked the version being used on their comptuer and it is 8.0.6001.18702, which is the same version as the one installed on my local machine which is working fine. Another user has logged into the computer being used by the user with the issues and it works fine for the second user.

This has stumped me for the last couple of hours and I was wondering if anyone else could shed some light... I have a page which loads some cookies, when taking the value from the cookie it defines whether a checkbox should be ticked or not. This works if the value of the cookie is true but not if the value is false and it ticks the box anyway. The code is....
var widgetVal = loadCookie(widgetName);
switch(i){
case 1:
document.getElementById('calender_widget').checked = widgetVal;
break;
[Code]...
i is incremented each time in a for loop and a different cookie is loaded each time. As I said the code works if it set to true but not false however if I remove the variable and specify it as false it works.
