Form表单提交的常用几种方式

通过$.post() 进行提交：

例：

 

Function tijiao(){

   
var username =$("#username").val();

   
$.post("user!login.do",{ "username": "username" },

   
   function(data){

   
if(date.success==true){

   
alert("成功");

   
}else{

   
Alert("失败");

   
}

   
   }, "json");

 }

通过$.ajax()进行提交

例：

functionto_submit(){

var username = $("#username").val();

$.ajax({

                    type : "post",

                    url : '<%=path%>/user!login.do',

                    data : {“username”:username},

                    dataType :"json",

              success:function(result){

                      
if(result.success ==false){

                                
flag = false;

                      
}else{

                      
   flag = true;

                      
}

              }

           });

}

引入 jquery.form.js，通过ajaxForm ()实现提交

例：

functionto_submit() {

                    var options = {

                             url :'<%=path%>/user!login.do’,

                             type: 'POST',

                             dataType : 'json',

                             success :function(result) {

                                       if (result.success== false) {

                                               
alert("用户名或密码错误！");

                                       } else {

                                           
//跳转到成功页面

                                               
window.parent.location="";

                                       }

                             }

                    }

                    // 提交form

                    $('#myform').ajaxForm(options);

}
