I'm building a web application using Visual Studio 2012. I'm attempting to add word count into my textbox. However after adding the the javascript codes and the html codes. I receive the error as stated above.
Here is my javascript codeds
Code :
function validateLimit(obj, divID, maxchar) {
objDiv = get_object(divID);
if (this.id) obj = this;
var remaningChar = maxchar - trimEnter(obj.value).length;
if (objDiv.id) {
objDiv.innerHTML = remaningChar + " characters left";
}
if (remaningChar <= 0) {
obj.value = obj.value.substring(maxchar, 0);
if (objDiv.id) {
objDiv.innerHTML = "0 characters left";
}
return false;
}
else
{ return true; }
}
function get_object(id) {
var object = null;
if (document.layers) {
object = document.layers[id];
} else if (document.all) {
object = document.all[id];
} else if (document.getElementById) {
object = document.getElementById(id);
}
return object;
}
function trimEnter(dataStr) {
return dataStr.replace(/(\r\n|\r|\n)/g, "");
}

<script type="text/javascript" src="js/JScript.js" ></script>
ASPX codes, ( Html codes )

There are at least three ways to disable the use of unobtrusive JavaScript for client-side validation:
<configuration>
<appSettings>
<add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />
</appSettings>
</configuration>
System.Web.UI.ValidationSettings.UnobtrusiveValidationMode
static property to System.Web.UI.UnobtrusiveValidationMode.None
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:
<%@ Page Language="C#" UnobtrusiveValidationMode="None" %>
to add a little more to the answer from b_levitt... on global.asax:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.SessionState;
using System.Web.UI;
namespace LoginPage
{
public class Global : System.Web.HttpApplication
{
protected void Application_Start(object sender, EventArgs e)
{
string JQueryVer = "1.11.3";
ScriptManager.ScriptResourceMapping.AddDefinition("jquery", new ScriptResourceDefinition
{
Path = "~/js/jquery-" + JQueryVer + ".min.js",
DebugPath = "~/js/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"
});
}
}
}
on your default.aspx
<body>
<form id="UserSectionForm" runat="server">
<asp:ScriptManager ID="ScriptManager" runat="server">
<Scripts>
<asp:ScriptReference Name="jquery" />
</Scripts>
</asp:ScriptManager>
<%--rest of your markup goes here--%>
</form>
</body>
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:
<appSettings>
<add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />
</appSettings>
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);
}
}
}
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.
Step1:
Step2 :
It will resolve your problem.
I believe I have encountered the same quandary. I started encountering the problem when I changed to:
</system.web>
<httpRuntime targetFramework="4.5"/>
Which gives the error message you describe above.
adding:
<appSettings>
<add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />
Solves the issue, but then it makes your validation controls/scripts throw Javascript runtime errors. If you change to:
</system.web>
<httpRuntime targetFramework="4.0"/>
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:
<add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />
<httpRuntime targetFramework="4.5.1" />
with:
jQuery version 1.11.3
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 =>
<%@ Page Title="" Language="C#"
MasterPageFile="~/Master/MasteOfHotel.Master"
UnobtrusiveValidationMode="None" %>
it works for me and doesn't disrupt my other jQuery function.
