使用JavaScript打印网页指定DIV区域
绿水青山 · 2013-12-15 · via 博客园 - 绿水青山

JavaScript打印函数myPrint(obj):

JavaScript打印页面指定div区域原理:使用window.open()在浏览器打开一个新的页面(window), 使用 window.document.write()将指定div区域的内容写入新窗口文档,document.close()关闭文档,使用window.print()调用打印机打印当前文档。

function myPrint(obj){
    //打开一个新窗口newWindow
    var newWindow=window.open("打印窗口","_blank");
    //要打印的div的内容
    var docStr = obj.innerHTML;
    //打印内容写入newWindow文档
    newWindow.document.write(docStr);
    //关闭文档
    newWindow.document.close();
    //调用打印机
    newWindow.print();
    //关闭newWindow页面
    newWindow.close();
}
