Question

我有一个带有代码的提交按钮，用于评估c＃中的内容，问题是我还想在javascript中添加一个函数，询问“此文件已存在，是否要替换它？

所以我的问题是如何触发两者？

OnClick="myC#mehod" and also OnClientClick =  return (some javascript);

我可以这样做吗？...

Answer 1

deleteBtn.Attributes["onClick"] = 
    "return confirm('This file already exists, do you want to replace it?');"

已更新以澄清;

<asp:Button ID="btnReplace" runat="server" onclick="btnReplace_Click" Text="Button" OnClientClick="return confirm('This file already exists, do you want to replace it?');" />

protected void btnReplace_Click(object sender, EventArgs e)
{
//Replace the File
}

Answer 2

OnClientClick="return confirm('This file already exists, do you want to replace it?');"

Answer 3

OnClientClick = "if(!confirm('This file already exists, do you want to replace it?')) return false;"

这比return直接

更安全
