MVC3----Ajax Helper method

===================ajax.actionlink

The ActionLink method can create an anchor label with one-step behavior.

For example:

Give the page a link, click on the link to display the information on the current page, instead of opening a new page

-- View Code:

@Ajax. ActionLink ("Ajax",//Page link name "Getajax",//Controller in method new ajaxoptions{Updatetargetid = "Getajax",//label to replace INSERTIONMO de = insertionmode.replace,//insert mode: replace label HttpMethod = "Get"//get request}) <!--manipulated label--><div id= "Getajax" ></ Div>

-- Controller code: (Returns a partial view to the foreground, need to create a getajax.cshtml view in the view)

Public ActionResult Getajax () {return this. Partialview ();}

===================ajax form

Case: Querying Data asynchronously

-- View Code:

<!--Ajax execution fails when executing a script--><script>    function loadfailure ()  {         $ ("#div1"). Text ("Failed to load");     }</script>@ using  (Ajax.beginform ("Personsearch",//Controller method      "Personerror",//Controller      new ajaxoptions ()  { //ajaxoptions object     httpmethod= "Get",//Submission method      insertionmode = insertionmode.replace,//Insert mode: Replace label      updatetargetid =  "Div1",//Operating label     LoadingElementId =  "Ajax-load",// When you click the Submit button, a status of the load is displayed (GIF loading image is used here)     onfailure= "Loadfailure"//execute a script when Ajax execution fails)) {     <input type= "text"  name= "Q"  />    <input  Type= "Submit"  value= "commit"  />    <!--loading status (GIF loading image is used here)-->     }<!--operated label-- <div id= "Div1" ></div>

-- Controller code:(return a partial view to the foreground, you need to create a personsearch.cshtml view in the View )

Public ActionResult Personsearch (string q) {var list = db. Schooltypes.where (r = r.st_name = = q). Select (r = r).    ToList (); return Partialview (list);}
