在ASP.NET中显示进度条

Posted 2020-07-28

版本1:

protected void Page_Load(object sender, EventArgs e)
    {
        Response.Write("<div id=‘mydiv‘ >");
        Response.Write("_");
        Response.Write("</div>");
        Response.Write("<script>mydiv.innerText = ‘‘;</script>");
        Response.Write("<script language=javascript>;");
        Response.Write("var dots = 0;var dotmax = 10;function ShowWait()");
        Response.Write("{var output; output = ‘正在装载页面‘;dots++;if(dots>=dotmax)dots=1;");
        Response.Write("for(var x = 0;x < dots;x++){output += ‘·‘;}mydiv.innerText = output;}");
        Response.Write("function StartShowWait(){mydiv.style.visibility = ‘visible‘; ");
        Response.Write("window.setInterval(‘ShowWait()‘,1000);}");
        Response.Write("function HideWait(){mydiv.style.display = ‘none‘;");
        Response.Write("window.clearInterval();}");
        Response.Write("StartShowWait();</script>");
        Response.Flush();
        Thread.Sleep(10000); 
    }

版本2:

public void showProessSource()
    {//实用代码 --- 在Page_Load事件里调用
        Response.Write("<div id=‘mydiv‘ style=‘text-align: center;‘ >");
        Response.Write("_");
        Response.Write("</div>");
        Response.Write("<script>mydiv.innerText = ‘‘;</script>");
        Response.Write("<script language=javascript>;");
        Response.Write("var dots = 0;var dotmax = 10;function ShowWait()");
        Response.Write("{var output; output = ‘正在加载页面······‘;");
        Response.Write("mydiv.innerhtml = output + ‘<br><img src=../images/waiting.gif />‘ ;}");
        Response.Write("function StartShowWait(){mydiv.style.visibility = ‘visible‘;ShowWait();} ");
        Response.Write("function HideWait(){mydiv.style.display = ‘none‘;}");
        Response.Write("StartShowWait();</script>");
        Response.Flush();
    }  

 

 

 

然后在前台页面最后加上:

<script>
HideWait();
</script>
