Detecting If Onscroll Events Working / Supported In Firefox
Jul 23, 2005
Is there a way to detect if an textarea onscroll event is working in
Firefox (or Mozilla). I know that there is an onscroll event bubbling
bug with current vesions of these browsers so I want to detect this
problem with a test like "if (textarea.onscroll == 'undefined' ||
!textarea.onscroll) {}."
Is there any way to get Mozilla to fire an event when a textarea scrolls? IE seems not to have a problem with it, but Moz just won't cooperate.
I tried the W3 event model: myTextArea.addEventListener("scroll", fn, true); - also tried "false" for the phase parameter (apparently this event neither bubbles nor captures).
I also tried the "singleton" event model: myTextArea.onscroll = fn;
I am working on a Javascript application and i am facing a strange behavior of the application in IE. I am creating a table at runtime using DHTML and registering event for the table row click. When i deploy this application on web server and browse the application, the events fires in firefox and chrome but in IE the events are not fired. If i browse the application from the server with localhost, the application triggers the events and fails when i use machine name.
The following is the source code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title></title>
I need to obtain a list of supported events on an encountered browser version programmatically, ie, via script. Since Explorer exposes its events on document object I can do something as simple as this:
;for(x in document)if(/^on/.test(x))alert(x);
(!warning: long list ahead..., you can use the console.log(x) instead) ..and simply store them on some appropriate object for latter use in my program flow.
Is there a sort of hack or "a hidden corner" or whatever, that would enable us to build a list of events available on Firefox in a similar fashion?
I'm trying to detect keystrokes using Javascript. My code (so far) works in Opera and Safari, but not in Firefox, Netscape/SeaMonkey/Mozilla, or Chrome. (I have no idea if it works in IE; IE has other problems with my code.)What I've done is attached a onkeydown listener to the body tag. (I've also tried it with onkeypress and onkeyup.) Right now all I'm trying to do is detect a key press -- any key press -- and throw an alert as a result. I've tried it two separate ways -- with straight Javascript and with MooTools, which I'm using for the rest of my project.
The code I have is as follows:
mootools version $(document.getElementsByTagName('body')[0]).addEvent('keypress', function(event) { alert('key has been pressed.'); }); regular javascript version document.getElementsByTagName('body')[0].addEventListener("keypress", function() { alert('key has been pressed.'); }, false);
Both versions work in Opera and Safari. Interestingly enough, if I attach a click listener to the body using the exact same code as above, but changing the word 'keypress' to 'click', they both work in Firefox as well. I can't figure out how to get this key listener attached.
I am writing a firefox extension and I need to execute a YQL query everytime the user changes webpage on their browser.For now, all i am concerned with is detecting if their is a webpage change.For example. User is on [URL] then switches to [URL] At this point i need to call a function.So far all i can find is an onload=function()Which is only working once when the browser opens up.
I am getting to learn JavaScript, and as for my first personal project, I would like to have a page with some text on it and when the user scrolls, a div containing a picture will move with the user when they scroll. I have found a solution, however, I do not like it.
<html> <head runat="server"> <title>Test</title>
[code]...
As you can see, it works by getting the scroll position and adding 250, to a height property-element above the image div. I have tried to use document.getElementById("image").style.top = scrollevel + 'px', but it does not work.
I have an absolute positioned navigation on my page that makes you jumps up or down the page to view some pictures placed in another absolute positioned DIV with scroll bar. The navigation is simply made by numbers: 1 2 3 4 5 6. When you rollover 2 is underlined and onclick the page jumps down to the second picture and the number 2 stays underlined, and so on for 3 4 5 6. The style changes this way
HTML <span id='first' class="selected"><a href="#1" onclick="first()">1 </a></span> <span id='secondo' class="normal"> <a href="#2" onclick="second()">2 </a></span> and so on for 3 4 5 6
[Code]....
What I would like to do is to make the style change automatically also when the user scroll the page instead of clicking. I thought I could control the y coordinate with window.onscroll but because what scrolls is the DIV and not the page the window.onscroll doesn't work. Is there a way to control the same way the scroll of a DIV? Or should I build the site differently?
It works perfect in ie, but in firefox I get permission denied to get property onscroll.why? and whats the solution? on top of my page i have done this though var url = document.URL;
I am trying to create a little code that when a user reads the rules they need to scroll right to the bottom of the textarea before the Select Option enables.heres my form:
HTML Code: <form method="post" name="form1" id="form1" action="http://www.maddogfitness.co.uk/cgi-bin/FormMail.pl">
When the page loads initally all events work. There is a button that does a postback but does not reload the page. If you try to execute any of the events that you previously did it does not recognise it.
I have this form entry <input type="text" onkeypress="return numbersonly(this,event); lessthan100(this);" name="discount_value" id="discount_value" value="" style="width: 40%;" maxlength="3" class="input-symbol-parent"> which calls two javascript functions. The first one works without a hitch... no letters can be entered into the field. However the next function (which at present time, just contains an alert) doesn't fire and I get no alert.I need to check if it's a number first. Below is the number checker.
I have a simple javascript overlay (like a lightbox) with a message that pops up. The user is meant to click a button, see the overlay thanking them for their vote, and then be redirected to the affiliate page (its a poll site) after about 3 seconds. I have everything down, except, it will either display the overlay as one of the onClick events, or it will do the timedRedirect but not both. I've tried putting the redirect before and after, and when its before it redirects, when its after, it shows the overlay. How can I do a timed redirect and show this message?
I'm trying to enable/disable a textarea. I am able to do a mouseout disable, but cannot do a mouseover enable. For instance, when I click on the image, a textarea shows up. When I move my mouse to a different location, the textarea disables fine.Then when I try to move my mouse back over the textarea, it DOES NOT enable for me to write in it.I just happen to try out this code in IE and the textareas are not showing up where I click. I assume that I'm capturing the X/Y coordinates incorrectly for an IE browser.

I've used to an AJAX call to load a HTML table into div. This is working successfully. I know want to use a click event on buttons located within the inserted table.
The click event is triggering on buttons outside the inserted table but not on the buttons within the table.
Do I need to call some sort of refresh function to so that jQuery is able to pick up these events?
I'm using jQuery SVG and would like to check if the browser that the person is using will support SVG --- if not, they'll receive a polite message; is there anyway to check this using javascript?
Is there anyway using Javascript, one can determine whether or not the browser viewing the page supports a particular CSS property or value? For example, I know IE6 doesn't support the value of "fixed" for the "position" property, so is there anyway I can determine this with Javascript, without resorting to browser sniffing?
I have are created dynamically buttonset toggle radio button with following code. All is working okay but just I have added onclick function which is doing window.location which is working with FireFox but not working with IE and google chrome.
<script type="text/javascript"> var chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'; $(function () { $('#btnSet').buttonstrip();
