如何强制秒表 - 从label1.text开始/停止？

问题描述

嗨
我正在练习一个小项目。根据鼠标移动，必须启动或停止秒表。

即，一旦鼠标在里面，然后启动秒表，否则停止。可能吗？

我的代码：aspx页

HiI am practicing a small project. According to mouse movements, the stop watch has to be started or stop.
ie, once the mouse is inside then start the stopwatch otherwise stop. Is it possible?
my codes: aspx page

<div id="Divn1" onmousemove="MyNewFunction(event)" onmouseout="ClearCoor()" style="width:99%; height:99%; border:solid;background-color:white; position:absolute;">
            <p id="Demo1"></p>
            <asp:Label ID="Label2" runat="server" Font-Size="XX-Large"></asp:Label>
            <div id="Divn2" style="width:50px;height:50px;border-radius:50%;background-color:brown; position:absolute; top:45%; margin-left:47%;">

            </div>
           <asp:scriptmanager ID="Scriptmanager1" runat="server"></asp:scriptmanager>
            <asp:UpdatePanel ID="UpdatePanel1" runat="server">
              <ContentTemplate>
                <asp:Label ID="Label1" runat="server" Font-Size="XX-Large"></asp:Label>
                <asp:Timer ID="tm1" Interval="1000" runat="server" ontick="tm1_Tick" />
              </ContentTemplate>
              <Triggers>
                <asp:AsyncPostBackTrigger ControlID="tm1" EventName="Tick" />
              </Triggers>
            </asp:UpdatePanel>

        </div>

然后是aspx.cs

And then aspx.cs

public static Stopwatch sw;
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            sw = new Stopwatch();
            sw.Start();
        }
    }
    protected void tm1_Tick(object sender, EventArgs e)
    {
        long milsecs = sw.Elapsed.Milliseconds;
        if (Label2.Text.Trim().Length > 0)
        {
            Label1.Text = DateTime.Now.ToString("00:ff");
        }
        sw.Stop();
        //Label1.Visible = false;
    }

谢谢
