我有一个网页，其中包含一个带有 7 个选项卡的菜单栏。菜单栏正下方是一个调用 javascript window.prin() 函数的打印按钮。但是，每次按下此按钮时，都会打印所有 7 个选项卡的页面。有什么方法可以准确指定要打印的页面吗？

在我的应用程序中，我使用弹出窗口来打印页面的一部分。

<script type="text/javascript">
    $(document).ready(function () {
        $('#printButton').click(function () {
            PrintElement($('#mainContent'));
        });
    });

    var PrintElement = function (element) {
        Popup($(element).html());
    }
    var Popup = function (data) {
        var mywindow = window.open('', 'print_div', 'resizable=1,scrollbars=1,height=400,width=600');
        mywindow.document.write('<html><head><title>Print Window</title><link href="../../Includes/Styles/Global.css" type="text/css" rel="Stylesheet" />');
        mywindow.document.write('</head><body><div id="mainMasterDiv">');
        mywindow.document.write(data);
        mywindow.document.getElementById("printButton").style.display = "none";
        mywindow.document.write('</div></body></html>');
        mywindow.document.close();
        mywindow.print();
        return true;
    }
</script>

一旦用户单击打印按钮，我将 resultDetailsDiv 传递给 PrintElement 函数，该函数会打开一个具有相同内容的弹出窗口，打印并关闭它。只有我必须使用 javascript 包含 css 来维护 div 内容的布局和样式。Popup 函数是用 Javascript 编写的，你可以尝试用 Jquery 编写函数，这样可以减少你的代码行。

printButton 是打印的按钮，mainContent 是包含要打印的内容的 div。
