When validating a form, it is often necessary to obtain the value of the element with name='***' in the form and then judge it. jQuery provides jQuery.serizlizeArray to serialize the form into an array. Even so, arrays are still inconvenient for us to operate. I need to serialize the form into an object. This makes it easier for us to operate.

The following is the code:

/** 
 * @author gaohuia 
 */
  
(function($){ 
  $.fn.extend({ 
    serializeObject:function(){ 
      if(this.length>1){ 
        return false; 
      } 
      var arr=this.serializeArray(); 
      var obj=new Object; 
      $.each(arr,function(k,v){ 
        obj[v.name]=v.value; 
      }); 
      return obj; 
    } 
  }); 
})(jQuery); 
/**
 * @author gaohuia
 */
  
(function($){
    $.fn.extend({
       serializeObject:function(){
           if(this.length>1){
              return false;
           }
           var arr=this.serializeArray();
           var obj=new Object;
           $.each(arr,function(k,v){
              obj[v.name]=v.value;
           });
           return obj;
       }
    });
})(jQuery);
