js将html导出word先说明缺点，导出的word⽂档没有html中的样式、适合导出⽂章类的html1、引⼊⽂件（下⾯有插件源码）<script type="text/javascript" src="../libs/jquery/1.11.1/jquery-1.11.1.min.js"></script> //jquery版本没有限制<script type="text/javascript" src="../libs/jquery/fileSaver.js"></script><script type="text/javascript" src="../libs/jquery/jquery.wordexport.js"></script>2、点击事件、使⽤插件、导出word$(function(){ $("button").click(function() {$("#content").wordExport("fileName"); //fileName为导出的word⽂件的命名,content为要导出的html内容容器html2canvas(document.getElementById("content"), {onrendered: function(canvas) {//通过html2canvas将html渲染成canvas，然后获取图⽚数据var imgData = canvas.toDataURL('image/jpeg');//初始化pdf，设置相应格式var doc = new jsPDF("p", "mm", "a4");doc.setFillColor(0,0,0);//这⾥设置的是a4纸张尺⼨doc.addImage(imgData, 'JPEG', 0, 0,210,297);//输出保存命名为content的pdfdoc.save('content.pdf');} });})3、注意：如果要导出的html内容在iframe中，并且含有图⽚，需要在html的img标签中设置跨域属性：crossorigin="anonymous" 否则导出的word中对应图⽚会不显⽰4、插件源码FileSaver.js/* FileSaver.js* A saveAs() FileSaver implementation.* 1.3.2* 2016-06-16 18:25:19** By Eli Grey, * License: MIT* See https:///eligrey/FileSaver.js/blob/master/LICENSE.md*//*global self *//*jslint bitwise: true, indent: 4, laxbreak: true, laxcomma: true, smarttabs: true, plusplus: true *//*! @source /github/FileSaver.js/blob/master/FileSaver.js */var saveAs = saveAs || (function(view) {"use strict";// IE <10 is explicitly unsupportedif (typeof view === "undefined" || typeof navigator !== "undefined" && /MSIE [1-9]\./.test(erAgent)) {return;}vardoc = view.document// only get URL when necessary in case Blob.js hasn't overridden it yet, get_URL = function() {return view.URL || view.webkitURL || view;}, save_link = doc.createElementNS("/1999/xhtml", "a"), can_use_save_link = "download" in save_link, click = function(node) {var event = new MouseEvent("click");node.dispatchEvent(event);}, is_safari = /constructor/i.test(view.HTMLElement), is_chrome_ios =/CriOS\/[\d]+/.test(erAgent), throw_outside = function(ex) {(view.setImmediate || view.setTimeout)(function() {throw ex;}, 0);}, force_saveable_type = "application/octet-stream"// the Blob API is fundamentally broken as there is no "downloadfinished" event to subscribe to, arbitrary_revoke_timeout = 1000 * 40 // in ms, revoke = function(file) {var revoker = function() {if (typeof file === "string") { // file is an object URLget_URL().revokeObjectURL(file);} else { // file is a Filefile.remove();}};setTimeout(revoker, arbitrary_revoke_timeout);}, dispatch = function(filesaver, event_types, event) {event_types = [].concat(event_types);var i = event_types.length;while (i--) {var listener = filesaver["on" + event_types[i]];if (typeof listener === "function") {try {listener.call(filesaver, event || filesaver);} catch (ex) {throw_outside(ex);}}}}, auto_bom = function(blob) {// prepend BOM for UTF-8 XML and text/* types (including HTML)// note: your browser will automatically convert UTF-16 U+FEFF to EF BB BFif (/^\s*(?:text\/\S*|application\/xml|\S*\/\S*\+xml)\s*;.*charset\s*=\s*utf-8/i.test(blob.type)) {return new Blob([String.fromCharCode(0xFEFF), blob], {type: blob.type});}return blob;}, FileSaver = function(blob, name, no_auto_bom) {if (!no_auto_bom) {blob = auto_bom(blob);}// First try a.download, then web filesystem, then object URLsvarfilesaver = this, type = blob.type, force = type === force_saveable_type, object_url, dispatch_all = function() {dispatch(filesaver, "writestart progress write writeend".split(" "));}// on any filesys errors revert to saving with object URLs, fs_error = function() {if ((is_chrome_ios || (force && is_safari)) && view.FileReader) {// Safari doesn't allow downloading of blob urlsvar reader = new FileReader();reader.onloadend = function() {var url = is_chrome_ios ?
