Question

Let’s say that I have a DOM object:

var a = document.getElementById('parent')

I want to search all input inside element a.

What should I do in jQuery?

I want to disable all input inside a, like syntax below:

$('#parent input').attr('disabled',true);

I tried

$(a).children('input').attr('disabled',true);

but gave no results.

Note: var a is an element I got from another function.

Answer 1

$(a).find('input').prop('disabled', true);

children() just searches immediate children of the element while find() searches all descendants.

Update: Also consider sinsedrix’s remark on the difference between attr() and prop().
