2.把这两个插件放到工程下如图:
3.调用案例
第一步:在jsp或者html引入刚才放在工程下的插件文件
1 2 3 | <!-- 路径写全 --> <script type="text/javascript" src="${contextPath}/static/js/FileSaver.js"></script> <script type="text/javascript" src="${contextPath}/static/js/jquery.wordexport.js"></script> |
第二步:在页面上写一个按钮
1 | <button class="btn btn-primary" onclick="${me}.wordExport()">word导出</button> |
第三步:在页面上把需要导出的东西用
给套上
如图
第四步:在js中调用的代码
1 2 3 4 5 6 7 8 9 | me.wordExport = function() { //选择性到处把不想导出的内容先隐藏掉 $(".export,.btn-group").attr("style", "display:none;"); $(".fixed-table-pagination").attr("style", "display:none;"); $("#wordExportDiv").wordExport('生成word文档'); //导出后把刚才隐藏掉的东西放开 $(".fixed-table-pagination").attr("style", "display:block;"); $(".export,.btn-group").attr("style", "display:block;"); } |
第五步:点击word导出功能可以导出!
