避免在javascript中使用刷新按钮 [英] avoid refresh button in javascript
问题描述
我要避免页面refresh.so，如果用户刷新页面，我需要重定向错误页面.实际上，在我的项目中，当用户单击提交"按钮以执行某些操作时，我重定向了另一页面以显示计时器.我们设置了计时60秒内，用户ve在此时间内填写表格.当时间到时，表格消失并自动提交.但是，当用户单击刷新"按钮时，它将再次显示该表格.
因此，我需要避免执行刷新操作并重定向错误页面.我该怎么办?

推荐答案
尝试一下
try this
//this is only c# code
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Session["CheckRefresh"] = Server.UrlDecode(System.DateTime.Now.ToString());
}
}
protected void Button1_Click(object sender, EventArgs e)
{
if (Session["CheckRefresh"].ToString() == ViewState["CheckRefresh"].ToString())
{
Label1.Text = "Hello";
Session["CheckRefresh"] = Server.UrlDecode(System.DateTime.Now.ToString());
string str = "your code will save here or call save() method here";
}
else
{
Label1.Text = "Page Refreshed";
}
}
protected void Page_PreRender(object sender, EventArgs e)
{
ViewState["CheckRefresh"] = Session["CheckRefresh"];
}
