我的技术公众号(私信可加前端技术交流群)
群内气氛颇为不错，应该可能算为数不多专门进行技术交流的前端群，同时也涵盖后端技术产品交流，偶尔成员们会聊天摸鱼。
使用方法
<!-- 引入加入 导出pdf插件 -->
<script type="text/javascript" src="./static/html2canvas.js"></script>
<script type="text/javascript" src="./static/jspdf.debug.js"></script>
// 调用页面加水印方法
this.watermark({
"watermark_txt": "中国广东cc.gd"
});
// 调用下载pdf报告方法
downKcReport();
