ajax - How to remove the handler in javascript -

-

I am adding some documents, where this script will execute on AJAX calls each time.

But how can I remove the handler on the outcome of AJAX, where I tried to use Undanderer but its effect was affected for the first time.

Is there any way to check that this event is alive?

If you want to remove an event handler with javascript, you have to cancel it like this:

< / Div> 

  document.getElementById ("yourelement"). Remove Event Alisoner ("Your Event", Your Function);

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends.
