Hi,
I want to display a "Go to top"-Link on my website.
This link should only be visible, if the vertical scrollbar is visible.
How can I do this using JavaScript?
Thanks
I am developing some JavaScript that should work with either Prototype.js or JQuery, thus I need some way to identify what is the primary library in use. How can I do that?
My javascript looks like the following. I don't understand why these methods are all public though?
Something.RegisterNamespace("One.ABC");
(function(ABC) {
ABC.SayHello = function() {
alert('hello');
};
})(One.ABC);
So now I can do:
One.ABC.SayHello();
Is there a library that can be used for implementing undo/redo functionality for DOM element manipulations in JavaScript?
I'm writing an app that moves around DOM elements, enables editing and deletion of those elements. There are event-handlers and other objects associated with each element operated upon.
Not sure whether I need to roll my own implementation of the Command pattern for this. Surely, there must be something available? If not, suggestions and pointers would be a great help.
Hello,
I have a div element in HTML document.
I would like to extract all elements inside this div that starts with a known text (e.g. "q17_").
How can I achieve this using JavaScript ?
(If needed, for simplicity, I can assume that all elements inside the div are of type input or select.)
Thanks !

Hello,
I'm experiencing something really strange with my javascript in chrome with Date().format.
If I use the console and type:
d = new Date(Date.parse("2010-05-28"))
d.format("yyyy-MM-dd");
""
d._toFormattedString();
"Fri May 28 2010 00:00:00 GMT+0200 (W. Europe Daylight Time)"

Hi,
I have seen some captchas being decode using javascript, php, etc. How do they do it?
For example, very popular megaupload site's captcha has also been decoded.
I've seen this issue in php and javascript. I have this number: float 0.699
if I do this:
0.699 x 100 = 69.89999999999999
why?
edit
round(0.699 x 10, 2): float 69.90000000000001

I am developing Javascript app that will wrap every line of text entered inside iframe (designmode) with P (or div) like it happens by default in IE.
For now I am not pasting my code because I just started, the first problem is when i type some text in firefox and even before I click enter or calling any function firebug inserts
<br _moz_dirty="">
under the entered text.
Why? How can I prevent it?
If you still need my code please tell.
My firefox downloads the JSON response of an AJAX call as a file.
It's suppose to be handled by the JavaScript i.e. JSON object.
Can anyone explain how to stop this behavior or there is something I am missing.
Thanks.
i have a parent window and a child window. in javascript, i want a function in child window to be called whenever the parent window loads a new page. i'd like to use something similar to jQuery's $(document).ready() so that I don't have to worry about whether the parent is done loading yet - but ready() only appears to fire when the window loads the first page - but not when, say, a link is clicked in the parent and it loads a second page.
any suggestions? thanks.

Hello fellow front-end web h4X0|2s,
I was wondering if anyone had any resources, proof, or personal experience in using the age-old http/https JavaScript hack:
<script src="//someserver.com/js/script.js"></script>
Has anyone encountered issues in any of these browsers (IE 5.5+, FF2+, Chrome, Opera 9+, Safari 3+)? Has anybody had success stories?
Thank you for your help.
I have a Java Swing project for my class. I would like put it on my website so people can use it. However I'm not sure if there is a way to turn it into a servlet. Or do I need to know JavaScript? I'm confused. Is there a way to make my swing application into a servlet automatically?
I have a background image on top of which there is some text.
It is very hard to read the text because of the background.
I would like to add a white background just around the text itself, such that the text could be easily read. How can I accomplish this using CSS/Javascript/jQuery ?
I see examples where JavaScript code including jQuery and jslint use the notation below:
(function(){
// do something
})();
instead of:
// do something
I first thought this is just for local scoping, i.e. creating local variables for the code block without polluting global namespace. But I've seen instances without any local variables at all too.
What am I missing here?
Hi,
I am using a third party library that provide some callbacks for a widget, but I'm not sure what the callback parameter objects are (no docs on them).
Is there a way to just dump all the attributes of an object in javascript, then print them using alert(), maybe? I just want to see what methods and attributes they contain,
Thanks
