使用jquery和play framework 2.0

Question

I want to use jQuery to open a lightbox but it is causing the problem. Here is my Application.java code:

    @(products: List[Products])

    @import helper._

        <script type="text/javascript" src="../public/javascripts/jquery-1.7.2.min.js"></script>
        <!-- Add mousewheel plugin (this is optional) -->
        <script type="text/javascript" src="../public/javascripts/jquery.mousewheel-3.0.6.pack.js"></script>

        <!-- Add fancyBox main JS and CSS files -->
        <script type="text/javascript" src="../public/javascripts/jquery.fancybox.js?v=2.0.6"></script>
        <link rel="stylesheet" type="text/css" href="../public/stylesheets/jquery.fancybox.css?v=2.0.6" media="screen" />


        <script type="text/javascript">
        $(document).ready(function() {

$('.fancybox').fancybox();

// my code
           });
// rest of the code

It gives me the error

ReferenceError: $ is not defined showed in firebug. i even tried changing $ with jQuery but still it doesnt work at all. Also i saw that the jQuery gets loaded in the head section. Do help me with this.

conf/routes file:

# Routes
# This file defines all application routes (Higher priority routes first)
# ~~~~

# Home page
#GET     /                           controllers.Application.index()

# Map static resources from the /public folder to the /assets URL path
GET     /assets/*file               controllers.Assets.at(path="/public", file)

# Products list (to fetch the list of all the products)
GET     /products                controllers.Application.list

GET     /products/:id           controllers.Application.findAll1(id:Integer)

Answer 1

I think that your JS paths are wrong.

If you use the default Play config, your Javascript paths should look like:

<script type="text/javascript" src="/assets/javascripts/jquery-1.7.2.min.js"></script>
...

And ever better, using the reverse routing, you should use:

<script type="text/javascript" src="@routes.Assets.at("/javascripts/jquery-1.7.2.min.js")"></script>
...

The static assets are provided through a special route defined in your conf/routes file:

# Map static resources from the /public folder to the /assets URL path
GET     /assets/*file               controllers.Assets.at(path="/public", file)

This route simply makes a binding between your local public folder and the /assets Url.

Answer 2

This is the new way to reference assets:

@routes.Assets.versioned("javascripts/jquery-3.1.1.js")

More info here: https://www.playframework.com/documentation/2.5.x/Assets

Answer 3

here is the simple example of Jquery using ajax in play framework... Configure the Route 1st

Routes

This file defines all application routes (Higher priority routes first)

~~~~

Home page GET / controllers.Application.index GET /newUser controllers.Application.newUserSign GET /login

controllers.Application.signInUser GET /newUserSignUP
controllers.Application.newUserSignUP1 POST /newUserSignUP
controllers.Application.newUserSignUP POST /signIn
controllers.Application.signIn POST /userDetail
controllers.Application.userDetail GET /logout
controllers.Application.logout POST /sendRequest
controllers.Application.sendRequest POST /friendDetail
controllers.Application.friendList POST /requestList
controllers.Application.requestList POST /acceptRequest
controllers.Application.acceptRequest GET /shwUserDetail controllers.Application.shwUserDetail

And the application is as

package controllers

import models.User import play.api._ import play.api.mvc._ import net.liftweb.json._ import net.liftweb.json.JsonDSL import net.liftweb.json.Serialization.write import

scala.collection.mutable.ListBuffer

object Application extends Controller { implicit val format = DefaultFormats def index = Action { Ok(views.html.index()) } def newUserSign = Action { Ok(views.html.newUserSignUpForm()) } def newUserSignUP = Action { implicit request => val a = request.body.asFormUrlEncoded val id = a.get("id").head val fnm = a.get("fnm").head val lnm = a.get("lnm").head val email = a.get("email").head val res = a.get("res").head val num = a.get("num").head val pwd = a.get("pwd").head

 val obj = User(id, fnm, lnm, email, res, num, pwd); if (models.UserModel.create(obj) > 0) { Ok(views.html.newUserWlcmPage()) } else { Ok(views.html.Error()) } //Ok(" congratulation ur finally registered.. your id is " + id + " & your name is => " + fnm + " And you lives in ::" + res) } def newUserSignUP1 = Action { Ok(views.html.newUserWlcmPage()) } def signIn = Action { implicit request => val a = request.body.asFormUrlEncoded val id = a.get("id").head val pwd = a.get("pwd").head val data = models.UserModel.userDetail(id, pwd) 

Redirect(routes.Application.shwUserDetail).withSession("id" -> id)

// Ok(views.html.userInfoPage(data)).withSession("id" -> id) }

def signInUser = Action { Ok(views.html.login()) } def shwUserDetail = Action { implicit request => val id = request.session.get("id").get val usrDetail = models.UserModel.userDetail(id) Ok(views.html.userInfoPage(usrDetail)) } def userDetail = Action { implicit request => val b = request.body.asFormUrlEncoded if (!session.get("id").isEmpty) { val id = session.get("id").get //val password = b.get("pwd").head

  val data = models.UserModel.getAllUserDetail(id) Ok(write(data)) } else { Ok("") } } def sendRequest = Action { implicit request => val b = request.body.asFormUrlEncoded.get val receiver_id = b.get("receiver_id").get(0) val sender_id = request.session.get("id").get val data = models.UserModel.friendRequest(sender_id, receiver_id) Ok(write(Map("sucess"->true))) } def logout() = Action { println("You are successfully logout") Ok(views.html.logout()).withNewSession } def friendList = Action { implicit request => val b = request.body.asFormUrlEncoded 

val sender_id = request.session.get("id").get val data = models.UserModel.friendList(sender_id)

 Ok(views.html.requestConfirmation()) 

} def requestList = Action { implicit request => val sender_id = request.session.get("id").get val data = models.UserModel.requestList(sender_id) Ok(write(data))

  } def acceptRequest = Action { implicit request => val b = request.body.asFormUrlEncoded.get val friend_id = b.get("friend_id").get(0) val user_id = request.session.get("id").get val data = models.UserModel.acceptRequest(friend_id, user_id) Ok(write(Map("sucess"->true))) } } 

And the mole is as

package models import play.api.db._ import play.api.Play.current

import anorm._ import anorm.SqlParser._

case class User(id: String, fnm: String,lnm: String, email: String, res: String,num: String, pwd: String) case class User1(sender_id:String, receiver_id:String) object UserModel {

def create(obj: User) = {

 DB.withConnection { implicit Connection => val data = SQL("insert into user_detail values({id},{fnm},{lnm},{email},{res},{num},{pwd})").on("id" -> 

obj.id, "fnm" -> obj.fnm, "lnm" -> obj.lnm,"email" -> obj.email,"res" -> obj.res, "num" -> obj.num, "pwd" -> obj.pwd).executeUpdate()

  data } } def userDetail(id: String, pwd: String): List[User] = { DB.withConnection { implicit Connection => val dat = SQL("select * from user_detail where id='" + id + "' and pwd='" + pwd +"'") var data = dat().map(row => User(row[String]("id"),row[String]("fnm"), row[String]("lnm"), row[String]("email"),row[String]("res"),row[String]("num"),row[String]("pwd"))).toList data } } def userDetail(id: String): List[User] = { DB.withConnection { implicit Connection => val dat = SQL("select * from user_detail where id='" + id + "'") var data = dat().map(row => User(row[String]("id"),row[String]("fnm"), row[String]("lnm"), row[String]("email"),row[String]("res"),row[String]("num"),row[String]("pwd"))).toList data } } def friendRequest(sender_id:String,receiver_id:String)={ DB.withConnection{ implicit c=> val result=SQL("insert into request_table values ({sender_id},{receiver_id})").on("sender_id"->sender_id,"receiver_id"->receiver_id).executeInsert() println("------------------------------------\\n"+result); result } } def getAllUserDetail(id: String) = { DB.withConnection { implicit Connection => val dat = SQL("select * from user_detail where id!='" + id +"'") var data = dat().map(row => User(row[String]("id"),row[String]("fnm"), row[String]("lnm"), row[String]("email"),row[String]("res"),row[String]("num"),row[String]("pwd"))).toList data } } def friendList(user_id: String) = { DB.withConnection { implicit Connection => val dat = SQL("select * from friend_tbl where id!='" + user_id +"'") var data = dat().map(row => User(row[String]("id"),row[String]("fnm"), row[String]("lnm"), row[String]("email"),row[String]("res"),row[String]("num"),row[String]("pwd"))).toList data } } def requestList(sender_id: String) = { DB.withConnection { implicit Connection => val dat = SQL("select receiver_id from request_table where sender_id='" + sender_id +"'") var data = dat().map(row => row[String]("receiver_id")).toList data } } def acceptRequest(friend_id:String, user_id:String)={ DB.withConnection{ implicit c= 

Blockquote

  val result=SQL("insert into friend_tbl values ({friend_id},{user_id})").on("friend_id"->friend_id,"user_id"->user_id).executeInsert() println("------------------------------------\\n"+result); result } } } 

and after that configure the view page enter code here

Map static resources from the /public folder to the /assets URL path GET /assets/*file controllers.Assets.at(path="/public", file)
