In development projects, the front-end values are passed to the back-end. Sometimes there are one or two values in the JSP form, or all the values. If you pass them one by one at this time, it is definitely not a good idea, so use jQuery to provide The form serialization method can solve this problem very well. At the same time, it can be encapsulated into a general function. If the execution is successful, the respective callback function can be called to realize the respective functions.
The code is as follows:
function queryUserInfo(actionUrl,formId,fun){ var params=new Object(); //声明数组 $.each($("#"+formId).serializeArray(),function(index,param){ params[param.name] = param.value; //序列化表单 }); params['time']=new Date(); //1 $.ajax( { url : basePath+actionUrl, data : params,//没有1,可以这样写("#"+formId).serializeArray() type : 'POST', dataType:'json', async: false,//表示同步,等待服务端返回数据,才会执行后面的代码 success : function(obj) { fun(actionUrl,formId,obj); }, error: function() { alert("访问异常"); } }); }
Another way:
function setUserInfo(actionUrl,userid,username,fun){ var params=new Object(); //声明数组 params['user.id']=userid; params['user.name']=username; $.ajax( { url : actionUrl, data : params,//没有1,可以这样写("#"+formId).serializeArray() type : 'POST', dataType:'json', async: false,//表示同步,等待服务端返回数据,才会执行后面的代码 success : function(obj) { fun(actionUrl,formId,obj);//调用回调的函数 }, error: function() { alert("访问异常"); } }); }
