WebForms UnobtrusiveValidationMode要求'jquery'的ScriptResourceMapping。请添加一个名为jquery的ScriptResourceMapping(区分大小写)

我正在使用Visual Studio 2012构建一个web应用程序。我试图添加字数到我的文本框。但是在添加了javascript代码和html代码之后。我收到如上所述的错误。

这是我的javascript代码

代码:

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, "");
}

母版页中的服务器代码

<script type="text/javascript" src="js/JScript.js" ></script>

ASPX代码，(Html代码)

<tr>
<th style="width: 595px; height: 135px;">Official Report :</th>
<td colspan="4" style="height: 135px">
  <asp:TextBox ID="tbofficial" runat="server" Height="121px" TextMode="MultiLine" Width="878px" MaxLength="500"   ToolTip="Summary:(500 characters)" onkeyup="return validateLimit(this, 'lblMsg1', 500)" ></asp:TextBox>

再给b_levitt的答案补充一点…… global.asax:

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",

        }

在你的default.aspx上

其他回答

我相信我也遇到过同样的困境。我开始遇到这个问题时，我改变了:

</system.web>
<httpRuntime targetFramework="4.5"/>

它会给出上面描述的错误消息。

添加:

<appSettings>
  <add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />

解决了这个问题，但它会让你的验证控件/脚本抛出Javascript运行时错误。如果你改为:

</system.web>
<httpRuntime targetFramework="4.0"/>

你应该没问题，但是你必须确保你的代码的其余部分按照你想要的那样运行。您可能还必须放弃一些仅在4.5以后才可用的新功能。

附注:在实现此解决方案之前，强烈建议您阅读以下内容。特别是，如果你使用Async功能:

https://blogs.msdn.microsoft.com/webdev/2012/11/19/all-about-httpruntime-targetframework/

2017年4月更新: 经过一些实验和测试，我想出了一个可行的组合:

<add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />
<httpRuntime targetFramework="4.5.1" />

jQuery 1.11.3

你需要一张网。Config键启用4.5前验证模式。

ValidationSettings的更多信息: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: <appSettings> <add key="ValidationSettings:UnobtrusiveValidationMode" value="None" /> </appSettings>

由于控制验证器而发生的问题。只需添加J查询参考到您的网页，然后添加验证设置在您的网页。配置文件来克服这个问题。我也面临着同样的问题，下面给出了解决我问题的方法。

步骤1:

步骤2:

它会解决你的问题。

我没有禁用新功能，而是选择按照错误提示操作。在我的global.asax.cs中我添加了:

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"
    });
}

这来自msdn的一篇博文，文中强调了脚本资源映射的一些优点。我特别感兴趣的是基于“debug=true”、EnableCDN等对脚本文件的交付进行集中控制。
