推荐答案

由于这是网络，你必须先决定是否要使用回发或不回发更改标签的文本。使用回发意味着您可以在C＃中执行此操作，但在JavaScript中没有回发也很容易。



c＃ - 在按钮单击事件中

Since this is the web you have to first decide if you want to change the label's text with a postback or without a postback. With a postback means you can do it in C# but it's also easy to do without a postback in JavaScript.

c# - in the button click event

label1.Text = "SomeText";

javascript - 按钮的onclick功能

javascript - onclick function of the button

function SomeButtonClick(){
document.getElementById("label1").value = "SomeText";
}
