单击ASP.NET中的按钮后，如何开始倒计时？ [英] How can I start count down timer after clicking a button in ASP.NET?

问题描述

我想点击提交按钮而不是页面加载时启动倒计时器

I want to start the count down timer after I click on the submit button instead of when the page is loaded

protected void Timer1_Tick(object sender, EventArgs e)
        {
            if (TimeAllSecondes > 0)
            {
                TimeAllSecondes = TimeAllSecondes - 1;
            }

            TimeSpan time_Span = TimeSpan.FromSeconds(TimeAllSecondes);
            hh = time_Span.Hours;
            mm = time_Span.Minutes;
            ss = time_Span.Seconds;

            Label2.Text = "  " + hh + ":" + mm + ":" + ss;
        }

protected void Button1_Click(object sender, EventArgs e)
       {

      }

我的尝试：



我尝试在Button1_Click方法中调用Timer1_Tick方法作为Timer1_Tick（发送方，e），但它不起作用。

What I have tried:

I have tried calling the Timer1_Tick method as Timer1_Tick(sender, e) within the Button1_Click method , but it didn't work.

推荐答案

试试这个

try this

protected void Page_Load(object sender, EventArgs e)
       {
           if (!Page.IsPostBack) {
               Timer1.Enabled = false;
           }
       }

       protected void Button1_Click(object sender, EventArgs e)
       {
           Timer1.Enabled = true;
       }
