问题描述
我正在使用Google ReCaptcha V2，它在更新面板中.如果验证失败，则ReCaptcha在回发时消失. 我读过类似的主题，但尚未找到解决我问题的答案.
I am using Google ReCaptcha V2 and it is inside an updatepanel. IF validation failed ReCaptcha disappears on postback. I read similar topics but I have not yet found an answer that solves my problem.
请帮助！
我的ASPX代码:
<%@ Register Assembly="GoogleReCaptcha" Namespace="GoogleReCaptcha" TagPrefix="cc1" %>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
<form id="formRegister" runat="server">
<asp:ScriptManager ID="ScriptManagerRegister" EnablePartialRendering="true" runat="server"></asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanelRegister" hildrenAsTriggers="false" UpdateMode="Conditional" runat="server">
<ContentTemplate>
<asp:Panel ID="Panel1" runat="server"></asp:Panel>
<asp:Button ID="ButtonRegister" runat="server" Text="Registrera" CssClass="btn btn-primary btn-md" /><br />
<asp:Label ID="Label1" runat="server" Text=""></asp:Label>
</asp:Panel>
</ContentTemplate>
</asp:UpdatePanel>
</form>
</asp:Content>
我在C#后面的代码
GoogleReCaptcha.GoogleReCaptcha ctrlGoogleReCaptcha = new GoogleReCaptcha.GoogleReCaptcha();
protected override void CreateChildControls()
{
base.CreateChildControls();
ctrlGoogleReCaptcha.PublicKey = "My Public Key";
ctrlGoogleReCaptcha.PrivateKey = "My Private Key";
this.Panel1.Controls.Add(ctrlGoogleReCaptcha);
}
protected void Page_Load(object sender, EventArgs e)
{
ButtonRegister.Click += new EventHandler(ButtonRegister_Click);
}
protected void ButtonRegister_Click(object sender, EventArgs e)
{
if (ctrlGoogleReCaptcha.Validate())
{
//submit form
Label1.Text = "Success";
}
else
{
Label1.Text = "Captcha Failed!! Please try again!!";
}
}
推荐答案
在正文后使用此脚本
<body>
<script language="javascript" type="text/javascript">
function pageLoad()
{
$('.g-recaptcha').each(function (index, obj) {
grecaptcha.render(obj, { 'sitekey': 'yoursitekey' });
});
}
</script>
