问题描述

JavaScript代码window.print()可以打印当前的HTML页面。

The JavaScript code window.print() can print the current HTML page.

如果我在HTML页面中有一个div(例如,从 ASP.NET MVC 视图),然后我想打印div。

If I have a div in an HTML page (for example, a page rendered from an ASP.NET MVC view), then I want to print the div only.

是否有任何jQuery 不引人注目的JavaScript 或正常用于实现此请求的JavaScript代码?

Is there any jQuery unobtrusive JavaScript or normal JavaScript code to implement this request?

使其更清晰,假设呈现的HTML页面如下:

Making it more clear, suppose the rendered HTML page is like:

<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>

然后我想点击打印按钮,只打印div3。

Then I want to click on the Print button, only printing div3.

推荐答案

我会这样做:

<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>
