JavaScript代码window.print()可以打印当前的HTML页面。
如果我在HTML页面中有一个div(例如,从ASP.NETMVC视图呈现的页面),那么我只想打印div。
是否有jQuery兼容的JavaScript或普通的JavaScript代码来实现此请求?
更清楚地说,假设呈现的HTML页面是这样的:
<html xmlns="http://www.w3.org/1999/xhtml"> <head id="Head" runat="server"> <title> <asp:ContentPlaceHolder runat="server" ID="TitleContent" /> </title> </head> <body> <div id="div1" class="div1">....</div> <div id="div2" class="div2">....</div> <div id="div3" class="div3">....</div> <div id="div4" class="div4">....</div> <div id="div4" class="div4">....</div> <p> <input id="btnSubmit" type="submit" value="Print" onclick="divPrint();" /> </p> </body> </html>
然后我要单击“打印”按钮,仅打印div3。
我会这样处理:
<html> <head> <title>Print Test Page</title> <script> printDivCSS = new String ('<link href="myprintstyle.css" rel="stylesheet" type="text/css">') function printDiv(divId) { window.frames["print_frame"].document.body.innerHTML=printDivCSS + document.getElementById(divId).innerHTML; window.frames["print_frame"].window.focus(); window.frames["print_frame"].window.print(); } </script> </head> <body> <h1><b><center>This is a test page for printing</center></b><hr color=#00cc00 width=95%></h1> <b>Div 1:</b> <a href="javascript:printDiv('div1')">Print</a><br> <div id="div1">This is the div1's print output</div> <br><br> <b>Div 2:</b> <a href="javascript:printDiv('div2')">Print</a><br> <div id="div2">This is the div2's print output</div> <br><br> <b>Div 3:</b> <a href="javascript:printDiv('div3')">Print</a><br> <div id="div3">This is the div3's print output</div> <iframe name="print_frame" width="0" height="0" frameborder="0" src="about:blank"></iframe> </body> </html>
