javascript - change event not firing after setting value dynamically

Question

I want to bind change event to textarea(read only) whenever its value is set dynamically by opening popup window.

I am able to set the value, but the change event is not getting fired.

I used below code to bind change event to textarea :

$('textarea[name="Cordinator"]').bind("change", onChangeCordinator);
function onChangeCordinator(){}

How are you setting the value? By default the change event fires only if the value is changed by the browser user.

If you are setting the value programatically you need to use .trigger('change')

So somewhere in your onclick handler you need:

$('textarea[name="Cordinator"]').trigger('change');
