jQuery事件丢失在ajax加载的内容

Question

Let's say that I have some HTML content in which I have some textareas. This HTML content is loaded through Ajax after performing some kind of action (like a button click or something). The problem that I have is that I lose all kinds of jQuery events that were bond to my textareas (like the .change event or something, so if I do something like:

$('.my_textarea').change(function(){
    alert('TEST');
});

My alert does not display because my textarea has been loaded with Ajax. Does anybody have any idea why this problem happens and how I can fix this?

Thanks in advance for any suggestions

Answer 1

$(document).on('change', '.my_textarea', function(){
    alert('TEST');
});

Just replace document with the closest static ( not loaded via Ajax ) parent of your textarea
