Validate ({    rules: {       //Name of the form to validate         Operationcode: {            //custom validation rules             Numorletter:true ,             //ajax checksum verifies whether the user's lost content exists in the database through the background service. Background service only needs to return True or False, Boolean type, String type can be               remote:{               // Here by get method, the parameter is placed after the URL, just start? After writing operationcode=, after the request is sent, the URL becomes?operationcode=&operationcode=value                //So it's removed.                URL: "${ctx}/ Operation/operation/validatecode? "+ $ (" #operationCode "). Val (),                 type: "GET",                 datatype: "JSON"                 //post mode, you can use                 //data:{paramname:value,...} Pass Parameters            }         }    },    messages:{        operationcode:{           //Specify error messages here              Remote: "The specified number already exists" &Nbsp;       }    }});
