Rewriting .each() loop as for loop to optimize, how to replicate $(this).attr()
- by John B
I running into some performance issues with a jquery script i wrote when running in ie so I'm going through it trying to optimize any way possible. Apparently using for loops is way faster than using the jQuery .each method. This has led me to a question regarding the equivalent of $(this) inside a for loop. I'm simplifying what I'm doing in my loop down to just using an attr() function as it gets across my main underlying question.
Im doing this with each(simplified)
var existing = $('#existing');
existing.each(function(){
console.log($(this).attr('id'));
});
And I've tried rewriting it as a for loop as such:
var existing = $('#existing');
for(var i = 0;i < existing.length;i++)
{
console.log(existing[i].attr('id'));
}
Its throwing an error saying:
Uncaught TypeError: Object #<HTMLDivElement> has no method 'attr'
Thanks.
