网页转word，一般都是将网页标签内容复制到word中，存在主要的两个问题：1. 页面样式丢失 2. 页面图片丢失，如果页面中有图表就更悲剧了； 如果是网页转pdf，现在技术比较成熟，html2Canvas就搞定了。
对于网页中的图片与图标资源，要想展示在word中，只有一种方案，那就是通过转换为图片的base64形式。
进入正题，直接上vue代码：
定义word导出组件
//导入js文件
import saveAs from "file-saver"
import $ from "jquery"
if (typeof jQuery !== "undefined" && typeof saveAs !== "undefined") {
(function() {
$.fn.wordExport = function(fileName,rules) {
fileName = typeof fileName !== 'undefined' ? fileName : "jQuery-Word-Export";
var static_ = {
mhtml: {
top: "Mime-Version: 1.0\nContent-Base: " + location.href + "\nContent-Type: Multipart/related; boundary=\"NEXT.ITEM-BOUNDARY\";type=\"text/html\"\n\n--NEXT.ITEM-BOUNDARY\nContent-Type: text/html; charset=\"utf-8\"\nContent-Location: " + location.href + "\n\n<!DOCTYPE html>\n<html>\n_html_</html>",
head: "<head>\n<meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\">\n<style>\n_styles_\n</style>\n</head>\n",
body: "<body>_body_</body>"
}
};
var options = {
maxWidth: 624
};
// Clone selected element before manipulating it
var markup = $(this).clone();
// Remove hidden elements from the output
markup.each(function() {
var self = $(this);
if (self.is(':hidden'))
self.remove();
});
// Embed all images using Data URLs
var images = Array();
var img = markup.find('img');
console.log(img.length)
for (var i = 0; i < img.length; i++) {
// calc word show size
var w = Math.min(img[i].width, options.maxWidth);
var h = img[i].height * (w / img[i].width);
// $(img[i]).attr("src", uri);
img[i].width = w;
img[i].height = h;
// base64 直接显示即可
var uri = img[i].src;
// Save encoded image to array
images[i] = {
type: uri.substring(uri.indexOf(":") + 1, uri.indexOf(";")),
encoding: uri.substring(uri.indexOf(";") + 1, uri.indexOf(",")),
location: img[i].src,
data: uri.substring(uri.indexOf(",") + 1)
};
}
// Prepare bottom of mhtml file with image data
var mhtmlBottom = "\n";
for (var i = 0; i < images.length; i++) {
mhtmlBottom += "--NEXT.ITEM-BOUNDARY\n";
mhtmlBottom += "Content-Location: " + images[i].location + "\n";
mhtmlBottom += "Content-Type: " + images[i].type + "\n";
mhtmlBottom += "Content-Transfer-Encoding: " + images[i].encoding + "\n\n";
mhtmlBottom += images[i].data + "\n\n";
}
mhtmlBottom += "--NEXT.ITEM-BOUNDARY--";
//TODO: load css from included stylesheet
var styles = rules;
// Aggregate parts of the file together
var fileContent = static_.mhtml.top.replace("_html_", static_.mhtml.head.replace("_styles_", styles) + static_.mhtml.body.replace("_body_", markup.html())) + mhtmlBottom;
// Create a Blob with the file contents
var blob = new Blob([fileContent], {
type: "application/msword;charset=utf-8"
});
saveAs.saveAs(blob, fileName + ".doc");
};
})(jQuery);
} else {
if (typeof jQuery === "undefined") {
console.error("jQuery Word Export: missing dependency (jQuery)");
}
if (typeof saveAs === "undefined") {
console.error("jQuery Word Export: missing dependency (FileSaver.js)");
}
}
