我想显示打印预览,所以我选择使用这个插件。
我已将其添加到我的代码中:
<%@ Page language="c#" AutoEventWireup="false" Inherits="System.Web.UI.Page" %>
<%@ Register TagPrefix="CP" TagName="TitleBar" Src="WebUserControl.ascx" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
<html>
<head>
<title>MyPage</title>
<link href="css/print-preview.css" rel="stylesheet" type="text/css" />
<link rel="stylesheet" href="css/print.css" type="text/css" media="print" />
<script type="text/javascript" src="jquery.tools.min.js"></script>
<script src="jquery.print-preview.js" type="text/javascript" charset="utf-8"></script>
<script type="text/javascript">
$(function () {
/*
* Initialise print preview plugin
*/
// Add link for print preview and intialise
$('#aside').prepend('<a class="print-preview">Print this page</a>');
$('a.print-preview').printPreview();
// Add keybinding (not recommended for production use)
$(document).bind('keydown', function (e) {
var code = (e.keyCode ? e.keyCode : e.which);
if (code == 80 && !$('#print-modal').length) {
$.printPreview.loadPrintPreview();
return false;
}
});
});
</script>
</head>
<body>
<form id="form1" runat="server">
<CP:TitleBar Title="User Control Test" TextColor="green" Padding="10" runat="server" />
<div id="aside"></div>
</form>
</body>
</html>
在UserControl
我这样做:
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="WebUserControl.ascx.cs" Inherits="WebUserControl" %>
<script src="jquery-1.7.2.min.js" type="text/javascript"></script>
<script type="text/javascript" language="javascript">
$(document).ready(function () {
$("p").text("The DOM is now loaded and can be manipulated.");
});
</script>
<p>Not loaded yet.</p>
<table>
<tr>
<td>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</td>
</tr>
</table>
问题是,当我在中添加脚本时UserControl
,Print-Preview-Plugin
它不起作用。
当我从作品中删除脚本时,UserControl
效果print-preview-plugin
很好。
我的问题是,为什么当我将脚本添加到 UserControl 时插件不起作用?我应该如何调用打印预览插件文件代码?
