Getting Ctrl Key Without Click Event?
Jan 23, 2011I am writing a callback functions that fit into a framework. Unfortunately, the framework does not provide any means of getting the initial onclick event. So, I tried doing the following to see if the ctrl key was pressed:
var ctrl=(window.event&&window.event.ctrlKey);
This didn't work. Is there a way to know if the ctrl key was pressed after the fact?

View 3 Replies View RelatedJQuery :: Stopping A Click Event With Another Click Event?
Nov 23, 2010I would like to create a plugin that I can put before a click event on a button. The click event should occur if the user's time on the page hasn't expired. The plugin should check the user's time, and then stop the click event if the time has expired. With the plugin, I'm essentially putting two click events on the same button, as I need to check the expiration when the button is clicked. The plugin is working on my test page, but I'm afraid that this is contingent on an arbitrary ordering of the click events by jQuery. If I have my click event chained after my plugin, can I be assured that the plugin would always stop the click event if the time is expired? Or could jQuery execute the click event before the time gets checked?
(function( $ ){
$.fn.checkExpiration = function(
$this = $(this);

Undo System For Text
Jul 23, 2005I`m writing a javascript regex tester (IE 6 only) and would like to include
an undo button for a text input field.
I want it to handle individual keystrokes, pasting and drop, and also
text added by clicking various buttons.
I have tried a LOT of handler combinations and fancy conditionals to
make it work perfectly, and I`m ALMOST there.
How Can I Restrict ExecCommand('undo') To A <div>?
Jul 23, 2005I am using IE 6.0. On a page, I have placed a contenteditable div
which I want to use as a Rich Text Area. I am using the execCommand method of
the document to control bold, italics, underlining, and undo for this div.
I have placed an input element on the page to. All but the undo, are
restricted to working only on the div. How can I restrict the undo to
working on only the div?
Below is the complete page so you can see what I am talking about.
Just paste it into an htm file and traverse to it via your browser.
Type something in the div and the input and then try the buttons. Code:

JQuery :: Text Undo Redo Machanism Like Googledocs/MS Word
Sep 6, 2010I find most rich internet text editors, developers put in the product many many features but fail to make a decent undo redo mechanism, I pressed crtl+z they deleted my whole paragraph. Unlike googledocs's one, it knows exactly what to undo.

Call The Click Event Of The Link (anchor Tag) On The Click Of The Button?
Jan 24, 2011I want to call the click event of the link (anchor tag) on the click of the button. I used this code below in the click event of button to call links click event and it works fine in IE.
document.getElementById('linktag').click();
But, this doesn't work in Firefox. I googled a bit and found that in firefox, you have to do something more to achieve this behaviour. So, I ended up doing this on button click to work in firefox:
var link=document.getElementById('linktag');
var e = document.createEvent('MouseEvents');
e.initEvent(
[code]....
The above code does the click on link when I click on the button. But my problem now is that I have defined a link as
<a href="mailto:abc@xyz.com?subject=abc&body=email body">email </a>
and when click is called and mailto links opens my email client, it somehow ignores the subject and body parameters of the link. It works properly when i actually click a link element. but it doesn't work when i simulate the click event by code written above. above dispatching event code somehow ignores the link parameters?

JQuery :: Triggering A Click Event Via (event.button != 0)?
Apr 8, 2010I have an object that has a click event I'm trying to trigger. However in the click event I have the following if statement:
if(event.button != 0){return true;}
This if statement allows right clicks to go through and activate but it also prevents me from triggering the event. Any ideas on how to prevent this? If I remove the if statement from the first click function everything works as intended.Here's my example code based off of the trigger event examples:

View 6 Replies View RelatedJQuery :: Dynamically Created Buttons Click Event Fires Last Bound Event For All Buttons?
Aug 24, 2011I create buttons from an array of objects that such as:
buttons = [{ text: "button 1", action: 1}, {text: "button 2", action: 2}];
I then loop thru the array to assign the text and bind the click event after having created the buttons with IDs of "button_<index>".
for( var index in buttons ) {
$("#button_"+index).html ( buttons[index].text )
.click( function() { clickButton( buttons[index].action ) } );
}
The text appears correctly in the button, but every button defined only fires the list bound click, in this example the action equal to'2'whether I push "Button 1" or "Button 2".My actual case has four buttons, all firing the event for the fourth button.I've tried not chaining the .click(), going thru the loop twice once for the .html and once for the .click, neither of which made a difference. If I hard code each button .click, it works fine.

View 4 Replies View RelatedDisabling CTRL-N In IE7
Apr 24, 2009I am using the following code for disabling Ctrl-N in IE7. It disables the Ctrl-N feature of IE which opens a new window containing the same page as the 'active' window. The code works great (at first glance). However, I noticed that, if you click anywhere inside the browser window and THEN press Ctrl-N, the new window will open. If you don't click anywhere inside the window, the following code works. Can anyone see an improvement to the following code so that clicking inside the browser window doesn't bypass the javascript?

Dec 15, 2011I would like to do this WITHOUT jQuery.
I have tried to get an event listener to listen for when the user presses Control-D on their keyboard. This would trigger a confirm delete function - if you've ever used QuickBooks Ctrl-D is the command that does this and this is a financial application.
Problem is that in FireFox, Ctrl-D means bookmark the page and this window pops up. I want to "return false" before this happens.
On this subject I would also like to take over Ctrl-C and Ctrl-V eventually but with Ctrl-D it will work for anything. here is what I have. Again, IT WORKS, but doesn't stop the natural event (bookmark page) fromhappening:
