定制的jQuery警报自动

我有一个网页，我用Visual Basic .NET下4.0开发关闭。我有一个简单的页面，有一些按钮。当我点击一个特定的按钮时，我执行一个使用jalert（）的javascript函数。该警报显示正确，但随后自行关闭，无需单击显示的对话框上的确定按钮。定制的jQuery警报自动

这是我的网页代码：

     jAlert('We encourage you to take the investment risk', 'Risk Category Selected'); 
    }  
</script> 

</body> 
</html>

这是我隐藏：

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 
    If (Not Page.IsPostBack) Then 
     Me.btn_Risk_M.Attributes.Add("onclick", "javascript:showPopup_M();") 
    End If 
End Sub

任何帮助是极大的赞赏。

谢谢乔纳森

您的按钮执行表单POST（回发）。这是正常的行为。回发将刷新页面，以便用JavaScript完成的任何客户端操作都将丢失。

，如果你不使用该按钮的任何asp.net功能的按钮属性更改为

btn_Risk_M.Attributes.Add("onclick", "showPopup_M(); return false;")

或（的OnClick，能见度等），你可以把它变成一个非ASPNET之一。

<input type="button" onclick="showPopup_M()" value="Risk" class="btn btn-primary btn-sm mobile-only" />
