运行功能是否成功（$ .ajax）具有200状态代码？

Question

I would like to use success and run function only if has 200 status code I have see only this example:

 $.ajax ({
   success: function(data,textStatus,jqXHR){
     external();
   }
 )};

But i never see a really code example i would like the if status code is 200 is run an external function

PS before i tried to use easy success (without arguments) and error, but error worked also if the external file was ok..

Sorry for my english

Answer 1

The success event is called when the request succeeds ( documentation ). The textStatus parameter should contain the string '200' or any other status number your server returned.

I hope the code you posted is partial: I don't see the url, method, etc. which should be passed as parameters to $.ajax .
