I have a piece of code that I dynamically load using globalEval(). But I am not able to debug this piece of code, specifically in IE, even when I place a "debugger;" statement.

Until now I have used the javascript function eval(), wrapped it in a try / catch block and showen him the error message if the javascript code was flawed.But this comes with the problem that if there is no error the script will be executed.So what I´d like to is use the jquery function globalEval(), wrap it in a try / catch block and display the error message if the script does not run sucessfully as I have done before,BUT:if the script would execute without an error I´d like to use some kind of preventDefault so that the script would not be executed at all and instead I could show the user a message that the script passed validation.I know that the way I propose is not possible as the script has to be executed somehow so that possible errors are generated...does anyone have an idea how to do what i propose ?
View 8 Replies View RelatedI keep getting a syntax error on line 3 and 4 of this very simple script. Normally firebug would give me enough info to fix this but jQuery escapes me. I can see no reason for the errors.
<script type="text/javascript">
$(".shipping-switch[name='shipping_switch']").click(function(){
var selector = "div#sub-address";
if($(this).val() === "1"){
$(selector).slideDown("fast");
} else {
$(selector).slideUp("fast");
}});
</script>
What is the best way to debug javascripts? Do it in Visual Interdev? Or just look at if any errors come from browsers.
View 2 Replies View RelatedI know this has to be easy, but I can't seem to figure it out. I'm debuggin' someone elses code...
x="hello";
+x+"world"
....and I don't get it! What does the "+x+"world" do? If I alert(x) the only thing that comes out is "hello". I also wondered why it doesn't error without the ";" at the end of the line.
When you write html or css then the validation proces is a good way of
finding errors. I get some syntax error / code: 0 errors in IE, how can
I figure out what the problem is. The thing is - it works - but it does
not look good when IE says the page is done with errors...

not Javascript code.

View 1 Replies View RelatedI have a couple of problems with my site related to javascript
These areas of the site use jquery and they work fine in Firefox and Chrome but not in IE
First problem is related to tablesorter and pager (jquery plugins) that give a properly paginated list of members in Firefox but gives all the returned members in one big list using IE (and usually a complaint that 'this script is taking too long' as well)
The other problem is related to the member search age, it has these expandable areas where the user can select further search criteria - they use jquery 'slider' to reveal the collapsed areas, again this works fine in Firefox or Chrome but looks messy in IE
To compound the problem the only javascript debugger I have is a plugin for Firefox called Venkman which I find pretty useful to find problems with AJAX etc, but seeing as the jquery/javascript stuff works OK in Firefox it's difficult to fix what isn't wrong there!
So really, how do I go about even beginning to understand these problems so I can fix them?

Can jquery animate the way a web page is loaded? for example you may fade in a page or add some effect to it when its loaded. is this possible?
View 1 Replies View RelatedI am developing a web application in which user can change the theme of the page.
So for this i am changing href attribute of the link tag on selection of the perticular theme.
Problem is that when i change the theme whole page gets messed up till the new css fileis fully loaded.
So how can I check if the CSS file is completely loaded or not?
I am using the following jQuery code:
$.get('/KarmaAppDev/Create/CreateFiltersPartial' + '?labelid=' + labelidval +
'&viewtype=' + viewtypeval + '&measureid=' + measureidval,
function (data) { $("#filters_container").html(data); });

I'm creating a script to get the next photo without reloading a webpage. To make it more smoothly, I fadeOut() the old image, and fadeIn() the new image.
However, when the new image is not yet fully loaded, the fadeIn() method doesn't really make sence. So I wonder if there is a way to first show an ajax loader, and after the new image is fully loaded, fadeIn the new image.
This is how far I got so far :-)
I first have to remove the first img tag, and inject a new one in the DOM, otherwise the old image flashes for a second, before the new one appears ;-)

I created a slideshow using the cycle-lite pluginLINK. LINK TO SLIDESHOW The slideshow is nearly great. The first time you load the images it is a bit bizarre. The images loads and fades at the same time.
Is there a way i can hide the images until all has loaded then trigger the slideshow.

View 5 Replies View RelatedI embedded a s3slider jquery plugin which has a sequence of more than 80 pictures.That causes a problem when loading the page,since when the slider starts the page completion get stuck.To overcome this I thought I could make it run after $(window).load and somehow it starts running after the page content is fully loaded but ... it has to wait for the whole set of 80 pictures which is not very practical. first it has to fully load the page content and graphics,except for the imgs under the slider, once that's done, instead of waiting for all the 80 pictures, it has to start running after the first 3 pictures of the banner are loaded...but this doesn't work...

I have a couple of links on my page (inside a <div id="theme-selector">) which allow you to change the CSS stylesheets:
$('#theme-selector a').click(function(){
var csslink = $(this).attr('href');
$('head link').remove();[code]...
Now, after I've changed the style on the page, I want to get the new background color, using the following code (which I put after the
$('head').append call):
var bgcolor = $('body').css('background-color');
alert(bgcolor);
The problem is, I think, that it takes some time for the browser to download the new stylesheet and I sometimes get the old background color in my alert message. Is there some event I can bind that will only alert me after all the stylesheets are loaded on the page? At the moment, all I can think of is using a setTimeout(function(), 5000); which isn't great, because what if it takes longer/shorter to load all the CSS on the page.
