推荐答案
你可以通过按钮点击导航到任何方向，比如prev和这样的嵌套为前一个
YOU can navigate by button click to any direction like prev and nest like this for previous
<input action="action" type="button" value="Back" önclick="history.go(-1);" />
<head runat="server">
<title></title>
<script type="text/javascript">
function Navigate() {
alert('hi');
history.go(-1);
}
</script>
</head>
<body>
<form id="form1" runat="server">
<input action="action" type="button" value="Back" önclick="Navigate();" />
</form>
</body>
</html>
试试这个：
页面加载：
Try this:
In page load:
previousPage = Request.UrlReferrer.ToString();
在previuos页面按钮点击事件：
In previuos page button click event:
Response.Redirect(previousPage);
我总共有四页，我已删除你的代码，以便你可以按照你的意愿使用
Default.aspx.cs
i have total have four page, i have removed your code so that you can use it as your wish
Default.aspx.cs
public partial class _Default : System.Web.UI.Page
{
int result = 0;
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
if (RadioButton1.Checked)
{
result += 5;
}
else if ((RadioButton2.Checked) || (RadioButton3.Checked))
{
result -= 2;
}
Response.Redirect("Default2.aspx?result=" + result);
}
}
Default2.aspx.cs
public partial class Default2 : System.Web.UI.Page
{
int result = 0;
protected void Page_Load(object sender, EventArgs e)
{
result =int.Parse(Request.QueryString["result"]);
}
protected void Button1_Click(object sender, EventArgs e)
{
if (RadioButton2.Checked)
{
result += 5;
}
else if ((RadioButton1.Checked) || (RadioButton3.Checked))
{
result -= 2;
}
Response.Redirect("Default3.aspx?result=" + result);
}
protected void Button2_Click(object sender, EventArgs e)
{
Response.Redirect("Default.aspx?result=" + result);
}
}
Default3.aspx.cs
public partial class Default3 : System.Web.UI.Page
{
int result = 0;
protected void Page_Load(object sender, EventArgs e)
{
result = int.Parse(Request.QueryString["result"]);
}
protected void Button1_Click(object sender, EventArgs e)
{
if (RadioButton3.Checked)
{
result += 5;
}
else if ((RadioButton1.Checked) || (RadioButton2.Checked))
{
result -= 2;
}
Response.Redirect("Default4.aspx?result=" + result);
}
protected void Button2_Click(object sender, EventArgs e)
{
Response.Redirect("Default2.aspx?result=" + result);
}
}
Default4.aspx.cs
public partial class Default4 : System.Web.UI.Page
{
int result = 0;
protected void Page_Load(object sender, EventArgs e)
{
result =int.Parse(Request.QueryString["result"]);
Label2.Text = result.ToString();
}
protected void Button1_Click(object sender, EventArgs e)
{
Response.Redirect("Default2.aspx?result=" + result);
}
}
its very urgent for me
