MVC2 uses jquery. Ajax to send and display data

The effect is as follows:

Click Submit to insert the data in the text box to the database.

Page SectionCode:

 

Jquery code:

$ ( Function  () {$ ( "# Sendmsg"). Click ( Function  () {// Triggered $. Ajax ({type: "Post" , URL: "/MSG/sendmicromsg /" , // Send to sendmicromsg action in msgcontroller. Datatype: "JSON" , Data :{ "Content": $ ("# contents"). Val ()}, // Insert the text in the "contents" ID to the database success:  Function  (Data) {// returned data. Alert (data );  }, Error:  Function  (Error) {alert ( "Error" );  }});  Return   False  ;});}); 

The following describes how to obtain parameters for the Controller:

  // /<Summary>          //  /Send Weibo messages          //  /</Summary>  Public actionresult sendmicromsg (formcollection frmcollection) {isession _ Session = SM. getsession (); string content = Frmcollection ["content" ]. Tostring (); // obtain the parameters passed by Ajax. You don't need to worry about other code. Now you know that the parameter is obtained. Write your inserted data. Trule = New  Trule (_ session); trule. Post (content, userrule. getcurrentuserid ()); Return  JSON (content); // here I can also return an object, or a piece of spliced HTML code: returned object: joson (New trule {id = 4, name = ""});}
