Catch statement does not catch thrown error

Question

For some reason this code gives me an uncaught exception error. It seems the catch block is not catching the error. Are try catch blocks scoped in such a way that I cannot t

Answer 1

Due to the asynchronous nature of the callback methods in javascript, the context of the function throwing the error is different compared to the original one. You should do this way:

success: function (result) {
  try {
    result = jQuery.parseJSON(result);
    if(!result.data.email){
      throw ('New exception');
    }
    console.log(result);
    jQuery('.email').html(result.data.email);
  }
  catch(err) {
    // Dealing with the error
  }
}

I would suggest you to have a look at this excellent article about the (very particular) contexts, closures and bindings in Javascript.
