写好邮件信息，单击定时发送按钮，弹出发送时间设置框，设置时间要早于系统当前时间。设置好后单击确定按钮，这封邮件会保存到草稿箱中，定时发送邮件和草稿箱其他邮件的区分的方式是通过判断时间是否早于当前时间，然后利用定时器和监听来实现每隔1分钟去数据库中查找草稿箱有没有发送时间等于当前系统时间的，如果有就发送，发送完成之后转到发件箱中。(Write E-mail information, click the send button regularly, pop-up send time Settings dialog, set a time to be earlier than the current system time. Click ok button after setting up, this email will save to draft box, timing to send the draft email and other mail box of distinguish way is by judging whether time is earlier than the current time, and then use the timer and listening to realize every 1 minute to draft database search box have send time is equal to the current system time, if there is sent, send after departure in the box.)

说明：  ## 视频截图工具 可以在预览视频的时候选择一个适合的界面把它截取下来，并存成图片。 ## 使用 ### 简单使用 主要文件： ``` <script src="poster.js"></script> ``` 在视频预览界面调用： ``` poster($('video')[0],function(e){ //console.log(e); if(e.bool){ //输出文件对象 var blob=e.data;//返回的是blob对象 console.log(blob); p.src=window.URL.createObjectURL(e.data);//创建一个临时预览路径 } }); ``` ### 使用extendvideo.js `extendvideo.js`与`poster.js`不同的是前者会在引入它的页面里每个`video`标签里增加一个`getPoster()`方法 。 用法： ``` var blob=$('video')[0].getPoster();//返回图片blob对象 ``` ## 原理 此视频截图工具，采用了canvas绘图函数实现video图片截取，产生base64编码图片信息，再通过转blob。 你的浏览器需要支持`HTML5`(### simple to use Main documents: . <script src= "poster.js" ></script> . Call on the video preview interface: . Poster ($('video') [0], function (E) {) //console.log (E); If (e.bool) { / / output file object Var blob=e.data; / / return is blob Console.log (BLOB); P.src=window.URL.createObjectURL (e.data); / / create a temporary preview path } }); . The use of extendvideo.js ### The difference between `extendvideo.js` and `poster.js` is that the former adds a `getPoster () method to each `video` tag in the page that is introduced to it. . Usage: . Var blob=$('video') [0].getPoster (BLOB); / / return picture object . ## principle This video capture tool uses a canvas drawing function to intercept video pictures, generate Base64 coded picture information, and then transfer blob. ## compatibility Your browser needs to support `HTML5`)
