asp.net中的“按需打印”(打印你需要打印的部分)

有时我们需要对asp.net网页中某些特定部分进行打印,很多人采用CSS样式或特定的打印控件来解决网页定制打印功能。这里采用Javascript样式替换方式进行打印,使网页显示与打印效果相分离。

过程很简单:

首先在asp.net页面中设定开始打印和结束打印的标记,为了确保该标记不在网页浏览时显示,我们采用"<!-- HTML注释 -->"的方式。比如:<!--startprint-->和<!--endprint-->。

接着写相关的JavaScript代码,具体代码见后。

如果不想打印按钮也被打印出来,注意将打印按钮包含在<!--startprint-->和<!--endprint-->之外。

相关代码:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="AppealPrint.aspx.cs" Inherits="Appeal.AppealPrint"

MasterPageFile="MasterPage.master" Title="诉求打印" %>

<asp:Content ID="Content1" ContentPlaceHolderID="CphNavigation" runat="server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="CphContent" runat="server">
<!--startprint-->
<style type="text/css">

    font-size:12px;
}
table{
    table-layout:fixed;
    empty-cells:show;
    border-collapse: collapse;
    margin:0 auto;

    font-size:12px;
    margin:0;
    padding:0;

table{
    border:1px solid #cad9ea;
    color:#666;

    height:30px;

table td,table th{
    border:1px solid #cad9ea;
    padding:0 1em 0;

   <table class="border" cellspacing="0" cellpadding="2" style="margin: 0px auto; width: 98%;border:1px solid;border-collapse:collapse;" id="TabBtnPrint">

                    </tr>
