Question

Using jquery is it better to create a DOM element like this:-

function create(options)
{
     $('<form action="' + options.action + '"></form>');    
}

Or like this:

function create(options)
{
     $form = $('<form></form>');
     $form.attr('action',options.action); 
}

This may be a matter of opinion. I feel that the second way gives more clarity but I suspect it is less efficient…

Answer 1

jQuery can create object as following code

$form = $('<form>', {action: 'my action'});

class is a reserved word in IE and needs to be quoted. See full list of reserved words: Reserved Keywords in Javascript
