How to use focus and blur on dynamic inserted elements? [duplicate]

Question

I have function:

$(document).ready(function(){

    $("input.myclass").focus(function() {
        // something
    }).blur(function() {
        // something
    });

}

and html:

<div class="usil">
    <div class="editable">
        <form>
            <input type="text" class="myclass" />
        </form>
    </div>
</div>

On load page jquery on "myclass" elements work fine but other script add dynamically "usil" class divs and on this divs jquery dont work. How to do it?

Answer 1

Use event delegation:

    $(document).on('focus',"input.myclass", function() {
        // something
    }).on('blur',"input.myclass", function() {
        // something
    });

or

$(document).on({
    'focus': function () {
        // something
    },
    'blur': function () {
        // something
    }
}, 'input.myclass');
