jQuery选择器以加载Ajax内容

Question

I have used this library: http://www.jacklmoore.com/autosize/

and in order to use it I should use syntax like below:

autosize($('textarea#description'));

or any other javascript selector. But my textarea loaded by ajax and it is not working.

Is there any other selector that works with ajax elements? Thank you

Answer 1

Just wrap the jquery selector around it and use .find() to narrow it down.

$.ajax({...}).done(function(responseHTML){
    // depending on what the function is doing you may need to append it to the body first.
    $(responseHTML).appendTo('body'); // or wherever you want to put it
    $textarea = $(responseHTML).find('#description');
    autosize($textarea);
});
