jQuery add attribute to html element and remove

You can add attributes using attr like below:

    $('#yourid').attr('name', 'value');

To remove:

    $('#yourid').removeAttr('name');

However, for DOM properties like checked, disabled and readonly, the proper way to do this (as of JQuery 1.6) is to use prop.

    $('#yourid').prop('name', 'value');

To remove:

    $('#yourid').removeProp('name');
