Handle synchronously thrown errors that were wrapped in jQuery() functions.

Shorthand version $.readyException()

Description

The jQuery.readyException() method fires when an Error JavaScript object is thrown synchronously from a jQuery() or jQuery( document ).ready() function or equivalent.

Default behaviour is to re-throw the error as a timeout so that it's logged in the console and also passed to window.onerror rather than being swallowed and lost.

The jQuery.readyException() method was added in jQuery 3.1.

Syntax

Parameters

Return

A Selector object.

jQuery.readyException( error ) Example Core  <<  Top

Re-throw caught error as a timeout so that it's logged in the console and also passed to window.onerror.

In the following example when we press the button the first time the jQuery.readyException() method gets fired.

$(function(){
  $('#btn18').one('click', function() { 
    var context = $('*').context; 
    jQuery.readyException = function( error ) {
      window.setTimeout( function() {
        throw error; 
      });
    };
  });
});
