[javascript] Is there a jQuery unfocus method?

How can I unfocus a textarea or input? I couldn't find a $('#my-textarea').unfocus(); method?

Guess you are looking for .focusout()

Based on your question, I believe the answer is how to trigger a blur, not just (or even) set the event:

 $('#textArea').trigger('blur');

This works for me:

// Document click blurer
$(document).on('mousedown', '*:not(input,textarea)', function() {
    try {
        var $a = $(document.activeElement).prop("disabled", true);
        setTimeout(function() {
            $a.prop("disabled", false);
        });
    } catch (ex) {}
});

I like the following approach as it works for all situations:

$(':focus').blur();

So you can do this

$('#textarea').attr('enable',false)

try it and give feedback
