I 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.
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 RelatedThis is a novice question, but I'm stumped. I have a variable with a bunch

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...
Is there any way to debug javascript in a web application? When I
develop JSP pages, and it has the javascript code in it. The problem is
the debugger in Java IDE (WSAD in my case) can only debug Java code but
not Javascript code.
What should I do to debug javascript code?
I know nothing of js yet, I'm still studying CSS & PHP. So I'm just looking for a ready made script for vertical scrolling. I found one that does exactly that, but all the css styling is done in the javascipt, so I was completely lost. I want to be able to just enter the html (into the js array if neccessary, I can do that much lol) and have it scroll upwards, simple as that. The nearest thing I could find to what I want is this Creating a vertical content scroller using DHTML I can style my div & images myself, then all I need to do is enter the html and away it goes, but it functions just like the marquee tag in that it waits for the entire content to clear before it starts scrolling again.

Form validation using JavaScript has never been as easy and simple! We
have developed a free generic form validation script that can validate
any form with very little JavaScript required in form!
For example:
A normal HTML form with out validation:
I 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>
I was wondering if there was an easy way to configure a message box to resemble that of a login form.It would preferably have two text fields for username/password and OK and Cancel buttons as well.I currently have a normal login form on my website designed using PHP but it does not figure into what we need to do now. I'm not sure about going about this and I have tried looking for quite sometime for an example of this but cannot find one.

View 5 Replies View RelatedIs there a way to change a javascript's output on a website without directly manipulating the source code? Just by entering some info in a form, then hitting submit. Then it automatically changes the content of a website.
What I want to happen is to change some text (specifically a news ticker) on my javascript, located in between the head tags, just by inputting new information on a form which automatically replaces the old one.
I 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?
I'm kind of new to js, I wanted to write some non english chars inside an array, and it only seems to work if I write unicode notation, e.g. "u1234" per char. I was wondering if there is some easier way to do this, maybe somehow specify to the browser that the js file is utf8-encoded or something similar, but I'm not sure how to do that.

I need to make a website that will be used as a traffic light system. So i will have a page with loads of divs starting red, that will change to green when clicked once, and back to red if clicked again, so on, so on. These changes will need to be viewable live on another computer, so changes need to save and will also need to automatically refresh without distrubing the rest of the page.
