    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)");
    }
}

二、导入

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

三、编写导出word核心代码

1

$("#download_word").click(function () {
        $("#test-editormd").html(testEditor.getHTML()).wordExport('resume');
});
