使用OnClientClick和onClick不應刷新頁面
[英]Using OnClientClick and onClick Shouldn't Refresh the Page
問題描述
我正在嘗試將onclientclick與onclick結合使用。 問題是頁面在運行任何javascript代碼之前都會刷新。 我正在嘗試將我的javascript代碼集成到其他人的代碼中。 我知道他的代碼中存在許多不良的編碼實踐，但是我需要使用它。 如果您想讓我更多地隔離代碼，我也可以這樣做。 我試過刪除onclick和onclientclick。 頁面仍刷新。

您需要從delayer函數返回false，還需要向OnClientClick事件添加return。
<asp:Button ID="Button3" runat="server" Text="Send Data"
OnClientClick="return delayer();" OnClick="Button3_Click" />
function delayer(){
showPopUp();
return false;
}
