回发期间的Recaptcha消失 [英] Recaptcha disappears during PostBack

问题描述

我看到的就在这里与ASP.net的UpdatePanel使用的Recaptcha的一对夫妇的其他职位，但还没有发现，解决我的问题的答案。

I have seen a couple of other posts on here regarding the use of Recaptcha with ASP.net UpdatePanels but have not yet found an answer that solves my problem.

下面是我的ASPX code：

Here is my ASPX code :

<asp:UpdatePanel ID="updRecaptcha" runat="server" UpdateMode="Always">
 <ContentTemplate>
  <recaptcha:RecaptchaControl ID="btnrecaptcha" runat="server" Theme="clean" PrivateKey"<%$ Resources: General, CaptchaPrivateKey %>" PublicKey="<%$ Resources: General, CaptchaPublicKey %>" />        
  <asp:Label ID="recaptchaerror" runat="server" style="color: Red;"/>
 </ContentTemplate>
</asp:UpdatePanel>

所以使用多个的.Net验证控件（例如的RequiredFieldValidator）的用户控件中的ReCaptcha控制生活。我需要让程序继续之前valdiate的ReCaptcha和ASP.net控制。

So the Recaptcha control lives within a user control that uses several .Net validation controls (e.g. RequiredFieldValidator). I need to valdiate the Recaptcha and the ASP.net controls before allowing the process to continue.

如果任何验证的失败（或的Recaptcha .NET），然后的ReCaptcha控制消失。纵观HTML源代码，该控件不加载回发后在所有 - eventhough我说的是UpdatePanel的更新

If any of the validation fails (Recaptcha or .Net) then the Recaptcha control disappears. Looking at the HTML source, the control isn't loading at all after the Postback - eventhough I am telling the UpdatePanel to update.

我不能完全重新加载页面，这一切都出现在页面顶部覆盖层和有其他表单域在页面上落后。

I can't reload the page completely as this all appears as an overlay on top of the page and there are other form fields on the page behind.

请帮帮忙！

编辑：

从C＃时的ReCaptcha失败我打电话这个code：

From C# when the Recaptcha fails I am calling this code :

ScriptManager.RegisterClientScriptBlock(Page, Page.GetType(), "InvalidRecaptcha", "alert('Recaptcha Failed');Recaptcha.reload();alert('Recaptcha Reloaded');", true);

这两个警报报表火，但仍的Recaptcha不会加载。

Both of the alert statements fire but the Recaptcha still does not load.

推荐答案

忘记的ScriptManager。所有你需要的是这个脚本在页面中。相应地更改您的标识符：

Forget the ScriptManager. All you need is this script in the page. Change accordingly for your identifiers:

<script type="text/javascript">
// RECAPTURE CODE FOR RELOADING AFTER INCORRECT ENTRY
if (typeof Sys != 'undefined') {
    var requestManager = Sys.WebForms.PageRequestManager.getInstance();
    requestManager.add_endRequest(function(sender, args) {

        $('<div id="recaptcha_widget_div"/>').appendTo('#recaptcha_widget_div2');

        if (typeof Recaptcha != 'undefined') {                                
            Recaptcha.create(recaptcha_key, "recaptcha_widget_div",
            {
                theme: "red",
                callback: Recaptcha.focus_response_field
            });
        }
    });
}
