SetAttribute doesn't work in IE7

Question

I'm using jQuery 1.6.1 and the attr() method, It's working fine on all browsers except IE7.

In the console, It highlights the setAttribute function in jQuery JS and says: Not Implemented

I think IE7 doesn't support that, so i tried to work around it:

if(Object.prototype.hasOwnProperty('setAttribute')){
  $(e).attr(key, value);
}else{
  e[key] = value;
}

It's still telling me:

Object doesn't support this action

What's the solution for this?

Well, the setAttribute method is certainly not defined on the Object.prototype object... It's defined on the Element interface of the DOM standard. — Šime Vidas

The setAttribute function in jQuery JS? But jQuery doesn't have a setAttribute function... Just $(e).attr(key, value); should work in IE7. — Šime Vidas

jQuery handles all odd cases well, there's usually no need to work around anything. Also note what Šime Vidas said, setAttribute isn't defined on Object.prototype and even if it would be, in IE8 and lower HTML elements don't inherit from Object so the feature detection wouldn't probably work as expected.

What's the value of key variable? Consider using prop() if more appropriate, or addClass() if you work with classes.

The value of key is src, or action, or href.

duri is exactly right. Even if setAttribute doesn't work on IE7, jQuery's .attr() does. The whole point behind jQuery is to smooth over these differences between browsers, and give you a framework where common actions will 'just work'.

Remove the conditional from your code, and just leave this:

$(e).attr(key, value);

Let jQuery handle the rest for you; that's what it's for.

If that still doesn't work, update your question with the values of e, key, and value, and people might be able to help further.
