getStyle and setstyle

[alejandro52]

// Get a style property (name) of a specific element (elem)
function getStyle( elem, name ) {
// If the property exists in style[], then it's been set
// recently (and is current)
if (elem.style[name])
return elem.style[name];
// Otherwise, try to use IE's method
else if (elem.currentStyle)
return elem.currentStyle[name];
// Or the W3C's method, if it exists
else if (document.defaultView && document.defaultView.getComputedStyle) {
// It uses the traditional 'text-align' style of rule writing,
// instead of textAlign
name = name.replace(/([A-Z])/g,"-$1");
name = name.toLowerCase();
// Get the style object and get the value of the property (if it exists)
var s = document.defaultView.getComputedStyle(elem,"");
return s && s.getPropertyValue(name);
// Otherwise, we're using some other browser
} else
return null;
}

 

This is some code to get the style of an element independent of the browser .How can i change it to set the style of an element. I think that it would be good to make some sticky topics on functions that are widely in use for bypass differences in browsers or sites that already have some of them.
