struts2 - callback method in jquery validation remote to get valid parameter -



struts2 - callback method in jquery validation remote to get valid parameter -

i using jquery validation validate form code -

$('form#register').validate({ rules:{ email:{ required:true, email:true, remote:{ url:"checkemail", type:"post", data:{ email:function(){ homecoming $('input#email').val(); } } } },captcha:{ required:true, remote:{ url:"checkcaptcha", type:"post", data:{ captcha:function(){ homecoming $('input#captcha').val(); } },success:function(data){ if(data.validcaptcha){ homecoming true; }else{ homecoming false; } } } } } });

i checking if mail service regisgtered application or not action checkemail. , validating captcha action checkcaptcha. both of url hitting same action. have next private field.

public class baseaction { private boolean validmail; private boolean validcaptcha; private string email; private string captcha; --getters , setters public string checkmail(){ userservice uservice = new userserviceimpl(); if(uservice.getuserbyemailid(getemail())!=null){ setvalidmail(false); }else{ setvalidmail(true); } homecoming success; } public string checkcaptcha(){ httpservletrequest request = servletactioncontext.getrequest(); string captchastored = (string)request.getsession().getattribute("captcha"); logger.info(captchastored+" = "+getcaptcha()); if(captchastored!=null&&captchastored.equals(getcaptcha())){ setvalidmail(true); }else{ setvalidmail(false); } homecoming success; } }

the problem jquery validation expect value true or false in response action gives response -

{"captcha":null,"email":"admin@ba.co","validcaptcha":false,"validmail":true}

i think it's struts action's default behaviour homecoming value of private property.

now question -

is there way tell struts action want value of valid captcha or validmail true or false. or

is there callback function in jquery validation can farther process response info , can check mail service or captcha validity myself , tell validator it's valid or invalid.

do not client-side...

success: function(data){ if(data.validcaptcha){ homecoming true; }else{ homecoming false; } }

... because that's handled internally plugin.

you're supposed output "false" (also undefined, null, or string) invalid or "true" valid server-side script , remote capture & handle response automatically.

documentation:

the serverside resource called via jquery.ajax (xmlhttprequest) , gets key/value pair corresponding name of validated element , value parameter. response evaluated json , must true valid elements, , can false, undefined or null invalid elements, using default message; or string, eg. "that name taken, seek peter123 instead" display error message.

you not need data parameter...

data:{ captcha:function(){ homecoming $('input#captcha').val(); } }

... because value of #captcha field beingness sent server-side script remote. data parameter used if need send additional info along request. please refer this illustration in docs.

this should need...

captcha: { required: true, remote: { url: "checkcaptcha", type: "post" } }

quote op:

"is there callback function in jquery validation can farther process response info , can check mail service or captcha validity myself , tell validator it's valid or invalid."

there's no reason that.

if response server true, you're telling jquery validate field "valid".

if response server false, null, undefined or string, you're telling jquery validate field "invalid". if homecoming string, must json formatted , become error message.

you need prepare server-side code conforms requirement. otherwise, cannot utilize jquery validate plugin.

quote op:

"is there way tell struts action want value of valid captcha or validmail true or false."

i'm no struts expert, instead of return success, have tried return true , return false in server side code? logic in struts action , homecoming appropriate boolean.
