extend整合



ex1. 

  var obj1 = { name: 'bob', age: 18, hobby: 'read' };
  var obj2 = { name: 'jimmy', gender: 'Male' };
  var newObj1 = $.extend(obj1, obj2);
  console.log( obj1 );
  console.log( obj2 );
  console.log( newObj1 );

 

IE11下的结果：

 

ex2.
  var obj1 = { name: 'bob', age: 18, hobby: 'read' };
  var obj2 = { name: 'jimmy', gender: 'Male' };
  var newObj2 = $.extend( {}, obj1
