Ajax submission on ASP. net mvc + JQuery master page, mvcjquery

<Pre name = "code" class = "javascript"> Ajax content:

$ (Document ). ready (function () {$ ("# submit "). click (function () {var name = $ ("# log "). val (); var pwd = $ ("# pwd "). val (); if (name. length = 0) {alert ("Enter the user name! ");} Else if (pwd. length = 0) {alert (" enter the password! ");} Else {$. post (".. /.. /Content/Handler. aspx ", {mName: name, mPwd: pwd}, function (data) {if (data =" right ") {window. location. href = "ManagerIndex. aspx "; // specify the page on which you want to switch after successful logon} else {alert (data );}});}});});});

Create a Handler. aspx page and write it in the background:

<Pre name = "code" class = "csharp"> protected void Page_Load (object sender, EventArgs e) {string name = Request. form ["mName"]. toString (); string pwd = Request. form ["mPwd"]. toString (); if (name = "hu") {Response. write ("right"); Response. end ();} else {Response. write ("incorrect user name or password! "); Response. End ();}}

Note the path of the master page. It is best to put the Handler. aspx page under the Contents directory.

Jquery:
$. Ajax ({

Success: function (msg ){
Msg is the data returned by ActionResult.
}
});

Public ActionResult test (here is the parameter list, for example, the parameter passed by ajax is {id: 1}. we can write it as a string id here)
{
This id is equal to 1.
/* ---- Add a database here ----*/
Dictionary <string, string> dict = new Dictionary <string, string> ();
Dict. Add ("infoId", "1 ");
Dict. Add ("infoMessage", "added successfully! ");
Return this. Json (dict );
}
