Hi
How to fire a javascript event on spacebar click.....I want to write this function on Master Page So it should work throughout my project................
There are buttons on every page...and on every page i have called a javafunction on click of the button...so its not posssible for me to make change to all the functions... iwant a global function which will take care of this...like wether i hit the enter button or space bar the javafunction should be fired
Please paste ur code here
Thanks in advanced

Associate the key down event to the document. Put this under the script tag in your master page, or in a js that is referred in the master page.
$(document).keydown(function(e)
{
var key = e.charCode ? e.charCode : e.keyCode ? e.keyCode : 0;
if (key == 32)
alert("space bar is pressed");
}
);
But, why on earth would you want to capture space key press across your application?

hi
Use below code for solution:
function addNewKeys(event)
{
if(!event) var event = window.event; // cross-browser shenanigans
if(event.keyCode === 32) { // this is the spacebar
saveTdsAddNew(event);
}
return true; // treat all other keys normally;
}
<a tabindex="7" style="cursor: pointer;" class="button" id="saveTocAddNew" onClick="saveTdsAddNew();"><span>Space bar Hit</span></a>
