在我代码这个基础上如何清空form表单 就是点击submit按钮提交后 表单清空，

在success:function(data){}函数的最后一行添加$("#form表单的ID")[0].reset();

 function clearForm(form) {
 // iterate over all of the inputs for the form  
 // element that was passed in 
 $(':input', form).each(function() {    var type = this.type;
 var tag = this.tagName.toLowerCase();
 // normalize case    
 // it's ok to reset the value attr of text inputs, 
 // password inputs, and textareas   
 if (type == 'text' || type == 'password' || tag == 'textarea')      this.value = "";   
 // checkboxes and radios need to have their checked state cleared   
 // but should *not* have their 'value' changed    
 else if (type == 'checkbox' || type == 'radio')      this.checked = false;   
 // select elements need to have their 'selectedIndex' property set to -1   
 // (this works for both single and multiple select elements)    
 else if (tag == 'select')   
 this.selectedIndex = -1;  }); }

在success函数里面就可以进行清空操作了 啊。。。。。
