Changing Page From location.hash

[jjacquay712]

I am starting to see many web applications like gmail and facebook use the url hash to dynamically change the page.

 

Ex. http://mail.google.com/#inbox

 

How could you make an event handler call when ever the anchor changes? OnLoad doesn't work because it isn't called when the anchor changes. You can get the text of the anchor using location.hash.

I figured out how to do! You have to check or "poll" every set amount of time to see if location.hash is different then what is was last. Here is my code if anyone is interested:

 

 

var lasthash = "";

function init() { //Call when page loads
setInterval("checkHash()", 100);
}

function checkHash() {
if ( lasthash !== window.location.hash ) {
	lasthash = window.location.hash;
	ajaxNavigate(lasthash); //This function uses ajax to update the page
}
}
