以下代码在没有更新面板的情况下工作,但在有更新面板时不运行。其目的是从后面或前面的浏览器按下清除页面条目上的bfcache。任何人都知道当用户点击/返回并且页面有更新面板时如何让js运行?
window.onpageshow = function(event){if(event.persisted){window.location.reload()}};
包含更新面板的整页:
<body>
<form id="form1" runat="server">
<ajaxToolkit:ToolkitScriptManager runat="server" ID="ToolkitScriptManager" />
<asp:UpdatePanel ID="updatePanel1" UpdateMode="Conditional" runat="server">
<ContentTemplate>
<script type="text/javascript">
var js = "window.onpageshow = function (event) { if (event.persisted) { window.location.reload() } };";
Sys.Application.add_load(js);
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_endRequest(js);
prm.add_beginRequest(js);
</script>
<a href='Default.aspx'>Default</a>
<a href='Default2.aspx'>Default2</a>
<a href='Default3.aspx'>Default3</a>
<a href='Default4.aspx'>Default4</a>
<br />
<div>
<asp:TextBox ID="tbText" runat="server"></asp:TextBox>
</div>
</ContentTemplate>
</asp:UpdatePanel>
</form>
尝试#2
<body>
<script type="text/javascript">
window.onpageshow = function (event) { if (event.persisted) { window.location.reload() } };
</script>
<form id="form1" runat="server">
<ajaxToolkit:ToolkitScriptManager runat="server" ID="ToolkitScriptManager" />
<asp:UpdatePanel ID="updatePanel1" UpdateMode="Conditional" runat="server">
<ContentTemplate>
<a href='Default.aspx'>Default</a>
<a href='Default2.aspx'>Default2</a>
<a href='Default3.aspx'>Default3</a>
<a href='Default4.aspx'>Default4</a>
<br />
<div>
<asp:TextBox ID="tbText" runat="server"></asp:TextBox>
</div>
</ContentTemplate>
</asp:UpdatePanel>
</form>
尝试#3
<body>
<form id="form1" runat="server">
<ajaxToolkit:ToolkitScriptManager runat="server" ID="ToolkitScriptManager" />
<asp:UpdatePanel ID="updatePanel1" UpdateMode="Conditional" runat="server">

<script type="text/javascript">
var js = window.onpageshow = function (event) { if (event.persisted) { window.location.reload() } };;
Sys.Application.add_load(js);
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_endRequest(js);
prm.add_beginRequest(js);
</script>
<a href='Default.aspx'>Default</a>
<a href='Default2.aspx'>Default2</a>
<a href='Default3.aspx'>Default3</a>
<a href='Default4.aspx'>Default4</a>

<div>
<asp:TextBox ID="tbText" runat="server"></asp:TextBox>
</div>
</ContentTemplate>
</asp:UpdatePanel>
</form>
答案 0 :(得分:1)
您的错误是您将字符串作为必须运行的代码的一部分。从此行中删除"
:
var js =
window.onpageshow =
function (event) { if (event.persisted) { window.location.reload() } };
还有一个,您可以从更新面板中删除该部分stript并将其放置在之前。
