JS实现Web中指定内容的保存与打印功能

作者:happylee6688 和javascript相关  

背景


首先,说说文章的背景。最近手中的一个项目,由于需求中要求提供Web界面的打印功能,当然如果没有打印机,还可以提供保存到本地。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,就马上开始了工作。


问题


刚开始的时候,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,然后就是各种的测试,由于 web 打印需要浏览器安装 ActiveX 组件,在随后的测试中,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。终于,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,我就开始走上了寻找新大陆的征途中,还好,我的运气不错,web 打印这个功能还是很常用的。很快我就有了一个新的解决方案。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,而且马上就展开了测试,通过测试,我发现这一款工具在各版本浏览器的兼容性表现还是不错的,至于功能方面,我需要的他都提供了,而且额外的功能也是很多的,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 组件还提供了另外一种方法,首先检测有没有安装插件,未检测到插件时,自动提示,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)
  • 需要引入的文件: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)
  • 需要在页面中加入对象引用



点击安装之后,浏览器就会自动的安装,然后就可以看到下面的提示了。





实现

  • 首先是打印功能

js 代码


<span style="font-family:Microsoft YaHei;font-size:12px;"><script type="text/javascript" src="LodopFuncs.js"></script>
<script type="text/javascript">
	var LODOP; //声明为全局变量
	// 打印预览
	function prn1_preview() {	
		CreateOneFormPage();	
		LODOP.PREVIEW();	
	};
	// 直接打印
	function prn1_print() {		
		CreateOneFormPage();
		LODOP.PRINT();	
	};
	// 选择打印机
	function prn1_printA() {		
		CreateOneFormPage();
		LODOP.PRINTA(); 	
	}; 
	// 创建打印页面
	function CreateOneFormPage(){
		LODOP=getLodop();  
		LODOP.PRINT_INIT("打印控件功能演示_Lodop功能_表单一");
		LODOP.SET_PRINT_STYLE("FontSize",18);
		LODOP.SET_PRINT_STYLE("Bold",1);
		LODOP.ADD_PRINT_HTM(10,20,500,5000,document.getElementById("form1").innerHTML);
	};
</script></span>


效果图





点击,打印预览之后,就会出现下面的效果:




当然,你还可以选择打印机,在打印预览里边也可以进入这个页面,只需要点击设置即可。




  • 然后是保存功能
html 代码相同,这里就不再重复贴了

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("");
			// 不打开模板直接加入内容
			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,就可以保存到word中了。
