Throw an exception from a passed string.

This method isn't much use outside of plugins as we can use the try....catch....finally construct for much better error handling. It does however give plugin developers the opportunity to override it with more meaningful error messages.


$(function(){
  $('#btn3').on('click', function() { 
    try {
      var anError = 3;
      if (anError < 5) {
        jQuery.error('ERROR: Value less than 5');
      } 
    } catch(e) {
      alert(' Our Message: ' + e.message);
    }
  });
});
