How to SET jquery .attr(), not get it

When I want to read an attribute, I use

$('#mydiv').attr('id');

How do I write to this attribute instead, so that I can change the id of the div in the markup?

It's more efficient and more cross-browser compatible just to use the element's id property:

$("#mydiv")[0].id = "newId";

Even better, you could cut out jQuery altogether:

document.getElementById("mydiv").id = "newId";

Include second parameter in attr call with value to set to.

$('#mydiv').attr('id', 'value');
