定製的jQuery警報自動

我有一個網頁，我用Visual Basic .NET下4.0開發關閉。我有一個簡單的頁面，有一些按鈕。當我點擊一個特定的按鈕時，我執行一個使用jalert（）的javascript函數。該警報顯示正確，但隨後自行關閉，無需單擊顯示的對話框上的確定按鈕。定製的jQuery警報自動

這是我的網頁代碼：

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

</body> 
</html>

這是我隱藏：

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

任何幫助是極大的讚賞。

謝謝喬納森

您的按鈕執行表單POST（回發）。這是正常的行爲。回發將刷新頁面，以便用JavaScript完成的任何客戶端操作都將丟失。

，如果你不使用該按鈕的任何asp.net功能的按鈕屬性更改爲

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

或（的OnClick，能見度等），你可以把它變成一個非ASPNET之一。

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