The problem occurred due to the Control validator. Just Add the J Query reference to your web page as follows and then add the Validation Settings in your web.config file to overcome the problem. I too faced the same problem and the below gave the solution to my problem.

Rather than disabling a new feature  I opted to follow the instructions of the error  In my global asax cs I added   protected void Application Start object sender  EventArgs e        string JQueryVer    1 7 1       ScriptManager ScriptResourceMapping AddDefinition  jquery   new ScriptResourceDefinition               Path      Scripts jquery-    JQueryVer     min js           DebugPath      Scripts jquery-    JQueryVer     js           CdnPath    http   ajax aspnetcdn com ajax jQuery jquery-    JQueryVer     min js           CdnDebugPath    http   ajax aspnetcdn com ajax jQuery jquery-    JQueryVer     js           CdnSupportsSecureConnection   true          LoadSuccessExpression    window jQuery              This comes from an msdn blog post which highlights some of the advantages of script resource mappings   Of particular interest to me was centralized control over the delivery of the script files based on  debug true   EnableCDN  etc

It has 3 solutions that other guys told upper    but when try Application Start solution  My other jQuery library like Pickup Date and Time doesn t work    so I test second way and it s answered   1- set the Target FrameWork to Pre 4 5 2- Use    UnobtrusiveValidationMode  None    in your page header      lt    Page Title    Language  C        MasterPageFile    Master MasteOfHotel Master       UnobtrusiveValidationMode  None    gt    it works for me and doesn t disrupt my other jQuery function

I believe I have encountered the same quandary  I started encountering the problem when I changed to    lt  system web gt   lt httpRuntime targetFramework  4 5   gt    Which gives the error message you describe above   adding    lt appSettings gt     lt add key  ValidationSettings UnobtrusiveValidationMode  value  None    gt    Solves the issue  but then it makes your validation controls scripts throw Javascript runtime errors  If you change to    lt  system web gt   lt httpRuntime targetFramework  4 0   gt    You should be OK  but you   ll have to make sure the rest of your code does  behaves as desired  You might also have to forgo some new features only available in 4 5 onward   P S  It is highly recommended that you read the following before implementing this solution  Especially  if you use Async functionality   https   blogs msdn microsoft com webdev 2012 11 19 all-about-httpruntime-targetframework   UPDATE April 2017  After some some experimentation and testing I have come up with a combination that works    lt add key  ValidationSettings UnobtrusiveValidationMode  value  None    gt   lt httpRuntime targetFramework  4 5 1    gt    with      jQuery version 1 11 3

There are at least three ways to disable the use of unobtrusive JavaScript for client-side validation    Add the following to the web config file   lt configuration gt     lt appSettings gt       lt add key  ValidationSettings UnobtrusiveValidationMode  value  None    gt     lt  appSettings gt   lt  configuration gt  Set the value of the System Web UI ValidationSettings UnobtrusiveValidationMode static property to System Web UI UnobtrusiveValidationMode None Set the value of the System Web UI Page UnobtrusiveValidationMode instance property to System Web UI UnobtrusiveValidationMode None   To disable the functionality on a per page basis  I prefer to set the Page UnobtrusiveValidationMode property using the page directive    lt    Page Language  C   UnobtrusiveValidationMode  None    gt

You need a web config key to enable the pre 4 5 validation mode   More Info on ValidationSettings UnobtrusiveValidationMode      Specifies how ASP NET globally enables the built-in validator controls   to use unobtrusive JavaScript for client-side validation logic       Type  UnobtrusiveValidationMode      Default value  None      Remarks  If this key value is set to  None   default   the ASP NET   application will use the pre-4 5 behavior  JavaScript inline in   the pages  for client-side validation logic  If this key value is set   to  WebForms   ASP NET uses HTML5 data-attributes and late bound   JavaScript from an added script reference for client-side validation   logic       Example        lt appSettings gt         lt add key  ValidationSettings UnobtrusiveValidationMode  value  None    gt       lt  appSettings gt

Unobtrusive validation is enabled by default in new version of ASP NET   Unobtrusive validation aims to decrease the page size by replacing the inline JavaScript for performing validation with a small JavaScript library that uses jQuery   You can either disable it by editing web config to include the following    lt appSettings gt     lt add key  ValidationSettings UnobtrusiveValidationMode  value  None    gt   lt  appSettings gt    Or better yet properly configure it by modifying the Application Start method in global asax   void Application Start object sender  EventArgs e         RouteConfig RegisterRoutes System Web Routing RouteTable Routes       ScriptManager ScriptResourceMapping AddDefinition  jquery           new ScriptResourceDefinition                       Path      Scripts jquery-2 1 1 min js                       Page 399 of Beginning ASP NET 4 5 1 in C  and VB provides a discussion on the benefit of unobtrusive validation and a walkthrough for configuring it   For those looking for RouteConfig   It is added automatically when you make a new project in visual studio to the App Code folder   The contents look something like this   using System  using System Collections Generic  using System Web  using System Web Routing  using Microsoft AspNet FriendlyUrls   namespace  default       public static class RouteConfig               public static void RegisterRoutes RouteCollection routes                        var settings   new FriendlyUrlSettings                settings AutoRedirectMode   RedirectMode Permanent              routes EnableFriendlyUrls settings
