我如何通过JavaScript和jQuery在word文档的标题中插入图像
通过使用jquery.wordexport.js和FileSaver.js我得到一个用给定数据创建的word文档，我必须在jquery.wordexport.js更改以获取word文档标题中的图像。
请建议使用代码或链接将受到很多赞赏。 提前致谢。
我的jquery.wordexport.js如下所示
if (typeof jQuery !== "undefined" && typeof saveAs !== "undefined") { (function($) { $.fn.wordExport = function(fileName) { 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\n\n_html_", head: "\n\n\n_styles_\n\n\n", 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'); for (var i = 0; i < img.length; i++) { // Calculate dimensions of output image var w = Math.min(img[i].width, options.maxWidth); var h = img[i].height * (w / img[i].width); // Create canvas for converting image to data URL var canvas = document.createElement("CANVAS"); canvas.width = w; canvas.height = h; // Draw image to canvas var context = canvas.getContext('2d'); context.drawImage(img[i], 0, 0, w, h); // Get data URL encoding of image var uri = canvas.toDataURL("image/png"); $(img[i]).attr("src", img[i].src); img[i].width = w; img[i].height = h; // 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]).attr("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 = ""; // 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(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)"); } }
我的FileSaver.js如下

wordexport.js利用Word在.doc文件中呈现HTML内容的能力。 所以答案就像将图像添加到HTML文档一样： img标记：
... 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\n\n_html_", head: "\n\n\n\n", body: "
_body_" } }; ...
根据此页面 ，适当地设置mso-element样式可用于指定页眉和页脚。 如果没有完全尝试，你可能还必须将页眉/页脚视为一个单独的文件（它在“文件的聚合部分”中合并在一起）：
