How to use jquery.validationengine Ajax validation __ajax

One: Add ajax validation to an element in a form

<form id= "EditForm" action= "#" method= "POST" >
    <input id= "user" name= "user" type= "text" value= "class=" Validate[required,ajax[ajaxnamecall]] "/>
    <input type=" Submit "value=" submitted "/>
</form>

Two: Define AJAX validation related parameters

$.validationenginelanguage.allrules.ajaxnamecall = {
                "url": "/admin/user/validate",
                //"message when validation fails
                " Alerttext ": * This name has been used by others",
                ///Verify the success of the message
                "Alerttextok": "The name can be used",
                "alerttextload": "* is verifying, please wait ... "
            };

Third: Start the verification mechanism

$ready (function () {
        $ ("#editform"). Validationengine ();
    

Four: server-side processing

Two parameters to the server: Fieldid,fieldvalue, which implements the judgment logic based on these two parameters, and then returns an array of three elements: the element ID, whether the check passes (true or false), and the hint information. Note that strings need to be enclosed by double quotes.
