推荐答案
在你的剧本周围放一个占位符
Put a placeholder around your script
<asp:Placeholder ID="PlaceScript" runat="server">
<script type="text/javascript">
function Show() {
document.getElementById('<%= bttn.ClientID %>').click();
}
window.onload = Show;
</script>
</asp:Placeholder>
然后在点击按钮时隐藏占位符
then hide the placeholder when the button is clicked
protected void bttn_Click(object sender, EventArgs e)
{
success.Visible = true;
PlaceScript.Visible = false;
}
删除此行
remove this line
window.onload = Show;
这将在页面加载后立即调用按钮单击事件，因此将发生无限循环。
this will invoke the button click event as soon as the page is loaded, hence infinite loop will occur.
以下是它发生的原因：onload设置为显示，此方法触发按钮单击。当您单击该按钮时，您的浏览器会向服务器发送请求并向您显示响应，这就是页面重新加载的原因。当页面重新加载时，显示再次被调用，因此它会一直持续。
我不知道你想要做什么，所以我不能说你现在要做什么，但如果你知道原因，你应该能够解决它。
Here is why it happens:onloadis set toShow, and this method triggers a button click. And when you click the button, your browser posts a request to the server and shows you the response, this is why the page reloads. And when the page reloads,Showis called again so it goes on forever.
I don't know what you want to do exactly so I can't say what you have to do now, but if you know the cause, you should be able to resolve it.
