大家好，又见面了，我是全栈君，今天给大家准备了Idea注册码。
背景
首先，说说文章的背景。近期手中的一个项目，因为需求中要求提供Web界面的打印功能。当然假设没有打印机，还能够提供保存到本地。项目组长把这个“小任务”分给了我。本着努力为组长分忧解难的思想，领了任务之后，就立即開始了工作。
问题
刚開始的时候。组长给了一个工具（jatoolsprinter）让我研究。我用了一个多小时的时间，做出了一个简单的Demo，然后就是各种的測试，因为 web 打印须要浏览器安装 ActiveX 组件。在随后的測试中，我用了几款浏览器。甚至把安全级别都调到了最低的要求， ActiveX 组件的安装总是不成功。之后的几个小时也在一直调这个问题。
最终，它打破了我耐心的底线，就这样被我“无情”的给抛弃了。
新大陆
吃过晚饭回来之后，我就開始走上了寻找新大陆的征途中。还好。我的运气不错，web 打印这个功能还是非经常常使用的。
非常快我就有了一个新的解决方式。在简单的了解了一下官方的说明之后，找了一个文档看了看。这次我吸取了上次的教训，我先把官方提供的插件制作成了 CAB。并且立即就展开了測试，通过測试。我发现这一款工具在各版本号浏览器的兼容性表现还是不错的，至于功能方面，我须要的他都提供了，并且额外的功能也是非常多的。足够我们开发使用了。对了。不得不提的是。他对浏览器安装 ActiveX 组件还提供了第二种方法，首先检測有没有安装插件。未检測到插件时，自己主动提示，并给出下载插件的地址，这里的插件使用的是 exe 格式的。这样就避免了浏览器安全设置的问题。
组件
- 组件名称：Lodop（提供下载）
- 须要引入的文件：lodop.cab（自己制作的）、LodopFuncs.js（必须的）、install_lodop32.exe（可选的，官方提供的exe格式插件）
- 须要在页面中增加对象引用
点击安装之后，浏览器就会自己主动的安装，然后就能够看到以下的提示了。
实现
- 首先是打印功能

点击。打印预览之后。就会出现以下的效果：
当然。你还能够选择打印机，在打印预览里边也能够进入这个页面。仅仅须要点击设置就可以。
- 然后是保存功能

js 代码
<span style="font-family:Microsoft YaHei;font-size:12px;"><script type="text/javascript">
// 导出为Word
function makeWord() {
var word = new ActiveXObject("Word.Application");
// 打开已有模板
// var doc = word.documents.open("");
// 不打开模板直接增加内容
var doc = word.Documents.Add("", 0, 1);
var Range=doc.Range();
var sel = document.body.createTextRange();
sel.moveToElementText(form1); //此处form1是页面上DIV的id
sel.select();
sel.execCommand("Copy");
Range.Paste();
word.Application.Visible = true;
//存放到指定的位置注意路径一定要是“//”不然会报错
doc.saveAs("D://股票投资营收明细.doc");
}
</script></span>
效果图
点击“导出为Word”之后，会出现一个与ActiveX控件交互的提示，点击“是”之后。就能够保存到word中了。
结束语
怎么样，非常easy吧！web 页面打印指定内容事实上就这么简单。
仅仅要找对好的工具，什么都不它是一个事！
