Jquery iOS8 ASP.net回调事件不工作

ASP.net按钮在iOS8上不起作用。按钮点击发生，但点击事件未触发。 同样的代码在其他浏览器（Chrome）中也能正常工作。 在iOS7上从未出现过此问题，即使对于Safari-此问题在iOS8更新后出现

以下是我在aspx页面中的代码：

<asp:Button runat="server" ID="btnLogin" Text="Next" OnClientClick="return fnValidateLoginData();"  />

以下是回调事件：

 protected void Page_Load(object sender, EventArgs e)
        {

            ac = new AuthenticationController();
            HttpContext hc = HttpContext.Current;
            #region ICallBack Reference

            // get reference of call back method named JSCallback 
            string cbref = Page.ClientScript.GetCallbackEventReference(this,
                            "arg", "fnGetOutputFromServer", "context");
            // Generate JS method trigger callback 
            string cbScr = string.Format("function fnCallServerMethod(arg," +
                                         " context) {{ {0}; }} ", cbref);
            Page.ClientScript.RegisterClientScriptBlock(this.GetType(),
                              "fnCallServerMethod", cbScr, true); 
    }

这可能有助于：

我们有一个类似的问题，它解决了我们的问题

干杯

 protected void Page_Load(object sender, EventArgs e)
        {

            ac = new AuthenticationController();
            HttpContext hc = HttpContext.Current;
            #region ICallBack Reference

            // get reference of call back method named JSCallback 
            string cbref = Page.ClientScript.GetCallbackEventReference(this,
                            "arg", "fnGetOutputFromServer", "context");
            // Generate JS method trigger callback 
            string cbScr = string.Format("function fnCallServerMethod(arg," +
                                         " context) {{ {0}; }} ", cbref);
            Page.ClientScript.RegisterClientScriptBlock(this.GetType(),
                              "fnCallServerMethod", cbScr, true); 
    }
