想要显示打印预览



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>

UserControl我这样做了:

<%@ 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UserControl中添加脚本时,Print-Preview-Plugin不起作用。

当我从UserControl中删除脚本时,print-preview-plugin工作正常。

我的问题是,为什么当我将脚本添加到用户控件时插件不起作用?我应该如何调用打印预览插件文件代码?

            var size = $.printPreview.sizeUpMask();
            mask.css({width: size[0], height: size[1]});
        }
    }
})(jQuery);

$('a.print-preview').printPreview()实际上不是一个函数,因为它没有这样的函数。

尝试类似操作:

$('a.print-preview').onClick(printPreview);
