推荐答案

有两种方法

1.在ASPX标记中，可以使用OnClientClick属性将JavaScript事件连接到ASP.NET按钮.

There are two ways of doing it

1. In the ASPX markup, you can use OnClientClick attribute to wire-up a JavaScript event to an ASP.NET button.

<asp:button id="btnSubmit" onclientclick="return ValidatePage();" xmlns:asp="#unknown"></asp:button>

2.在后面的代码中，您可以使用如下代码:

2. In the code-behind, you can use code like this:

btnSubmit.Attributes.Add("onclick", "return ValidatePage();");

您需要缩小一点，说出您要实现的目标，但总的来说

You''ll need to narrow it down a bit and say what you are trying to accomplish, but in general

<asp:button runat="server" onclientclick="return Foo();" />;
<script>
function Foo()
{
  // Do something
  //return false; // Don''t complete postback
  //return true; // Complete postback
}
</script>
