JSONP which i am receiving is :
({"movies":[{"ID":1,"Title":"Movie 1","ReleaseDate":"/Date(1355250600000)/","Genre":"Comedy","Price":10},{"ID":2,"Title":"Movie 2","ReleaseDate":"/Date(1355250600000)/","Genre":"Thriller","Price":10}]})
There must be a call back function name in the returned JSONP. The output I see here doesn't have any function name. You need to make changes to your server side code.

is there any way to call a controller function when someone click on a check box. Like There are 4 check box with each has a category so when a user click on particular category then it will hit an API that process the filter request from the backend. I searched on Google but there is option to change it to
But that I don't want. Do I have to use jquery or else?
As in the comment section you can achive this via JQuery/Javascript. I have added a simple example with JQuery for your reference. What I achive here is first catch all check un check events and then via Ajax I send a request to the server. So that controller function will get called. You can test this via network tab when you check or uncheck a checkbox.

My nodejs file is

module.exports = app;
My Angularjs page 1

using this code navigation dosen't happen. in url i got a # sign.While using location provider for removing # the link home is going to black. please help me
First, in your controller you forgot to add '/' to the url:
var app = angular.module('signApp', ['ui.router']);
app.config(function($stateProvider) {
//$locationProvider.html5Mode(true);
$stateProvider
.state('home', {
url: '/home',
views: {
'content#': {
templateUrl: 'templates/register.html',
controller: 'signCtrl'
}
}
});
});
app.controller('signCtrl', function($scope, $state) {
$state.go('home');
});
The second thing I noticed that is not right is that your second template contains
<!DOCTYPE html>
<html ng-app="signApp">
<head>
</head>
<body ng-controller="signCtrl">
you don't need all this, you need only the things that you will add to your page once you go to your view.
The third thing is that you should define two separate states 'home' and 'home.register'
.state('home.register', {
parent: 'home',
url: '/signup',
views: {
'#home': {
template: 'your template path '
}
}
})
.state('home', {
url: '/home',
views: {
template: 'your home template'
}
});
Below code has been thankfully provided by machun for toggling between RTL and LTR directions in Kendo UI widgets.
The code consists of:
HTML:
kendo autocomplete form plus a button to activate support for RTL and LTR language.
Script:
k-rtl class container
datasource (json file)
kendo autocomplete widget initializing + template to show image beside data and to open data links in the same tab
k-rtl class
The problem is that links don't open correctly. It shows a 404 Not Found error plus a /undefined at the end of the URL.

I advice to debug your function first then simply check the variable and make sure it contain the right thing. You overlooked a simple thing that your jquery dom selector isn't quite right resulting var href contain "undefined".
Change
var href = e.item.find("span").data("href");
To
var href = e.item.find("span[data-href]").attr("data-href");

When I enter special character as content as pass it to Ajax call I am getting an error :( Ajax call works fine with out any special characters...
Is there any way to encode the data before passing it to ajax call???Please help me on this...
Thanks in advance.
(1.)Either you should put your data into a form and serialize it and then send to the server
(2.)Second way is you can use the js inbuilt function encodeURIComponent().
On the click of a button i want to sumbit a form if another form, in the same page (not a ligthbox) is valid. That validation is a Custom Validation I created and is working fine.
This is the code in the view
$("#btnSave").click(function (e) {
if ($("#GeneralButtonFrm").valid()) {
$("#ButtonFrm").submit();
} else {
//Error Message
} });
The problem is that the submit action is executing without waiting for the response of the custom validation which return false.
Any idea why this is happening?
Note: I said I am not using a ligthbox rendering a partial becouse in that case the solution would be jQuery.validator.unobtrusive.parse('#form');
Thanks
You are still very vague, in your question. But i think what you want is to call ajax and do a serverside validation. If so, the problem is that your validation will return before ajax request since the ajax request is async.. Do this
<html>

<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/mvc/3.0/jquery.validate.unobtrusive.js"></script>
<script type="text/javascript">
jQuery.validator.addMethod("ajaxCustom", function (value, element) {
var wrap = $(element);
var url = wrap.data("customAjaxUrl");
var result;
$.ajax({

url: url,
dataType: 'json',
success: function (data) {
result = data.valid;
},
data: { value: value, id: element.id },
async: false
});
return this.optional(element) || result;
}, "Ajax");
$.validator.unobtrusive.adapters.addBool('ajaxCustom');
</script>
