Global var thoughout functions kinda thing

[matfish]

Hey,

 

Iv got a load of javascript functions in a .js file, but Iv had to manually hardcode each URL. I would like to put a variable like "dir" so I can use like a global directory:

 

function hide(which){
element =	document.getElementById(which);
anchr = document.getElementById('a_'+which);
img = document.getElementById('i_'+which);
element.style.display = 'none';
anchr.href = 'javascript:show(\''+which+'\')';
img.src = '/foldername/image_assets/expand.gif';
}

 

For example: the above; so that /foldername/ could be specified at the top of the .js file and would inherit throughout all the functions? Oh - trying without to pass a new variable through the function?

 

Anyone? Please? Thanks

somewhere in the javascript (outside the functions) create a variable called folder

var folder = "/foldername/";

 

Inside the function, just use that variable

...
img.src = folder+'image_assets/expand.gif';
}
