1.下载两个js

FileSaver.js    jquery.wordexport.js 网上有，我就不发了，哈哈

2.在html页面引入js

注意FileSaver.js要放在jquery.wordexport.js的上面，像这样

<script src="/js/FileSaver.js"></script>
<script src="/js/jquery.wordexport.js"></script>

3.添加一个按钮的点击事件


<input type="button" id="export" value="导出word"/>
<div id="export_word">
//要导出的部分
</div>

$("#export").click(function () {
   $("#export_word").wordExport("导出word的名字");
});

现在就可以导出word啦，不过现在word中只可以导出css内联样式，外联样式导出不了

4.导出css样式

以下是jquery.wordexport.js中修改的部分，多传了一个rule参数，在下面把styles赋值为rule，注意修改的地方一共有两处。

$.fn.wordExport = function(fileName,rule) {
            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');
            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 = rule || "";

然后html页面中的js修改为

        //传入css样式
        var rules = "",
            ss = document.styleSheets;
        for (var i = 0; i < ss.length; ++i) {
            for (var x = 0; x < ss[i].cssRules.length; ++x) {
                rules += ss[i].cssRules[x].cssText;
            }
        }
        $("#export").click(function () {
            $("#export_word").wordExport("导出word的名字",rules);
        }

这样就可以引入css了！
