该特效也是在Jquery插件库中找到的，感觉效果不错，说不定以后项目中要有绚丽的星空背景，拿来即用，收藏了下。

运行的效果如下：
其中stopExecutionOnTimeout.js如下：
复制代码 代码如下:
"use strict";"object"!=typeof window.CP&&(window.CP={}),window.CP.PenTimer={programNoLongerBeingMonitored:!1,timeOfFirstCallToShouldStopLoop:0,_loopExits:{},_loopTimers:{},START_MONITORING_AFTER:2e3,STOP_ALL_MONITORING_TIMEOUT:5e3,MAX_TIME_IN_LOOP_WO_EXIT:2200,exitedLoop:function(o){this._loopExits[o]=!0},shouldStopLoop:function(o){if(this.programKilledSoStopMonitoring)return!0;if(this.programNoLongerBeingMonitored)return!1;if(this._loopExits[o])return!1;var t=this._getTime();if(0===this.timeOfFirstCallToShouldStopLoop)return this.timeOfFirstCallToShouldStopLoop=t,!1;var i=t-this.timeOfFirstCallToShouldStopLoop;if(i<this.START_MONITORING_AFTER)return!1;if(i>this.STOP_ALL_MONITORING_TIMEOUT)return this.programNoLongerBeingMonitored=!0,!1;try{this._checkOnInfiniteLoop(o,t)}catch(n){return this._sendErrorMessageToEditor(),this.programKilledSoStopMonitoring=!0,!0}return!1},_sendErrorMessageToEditor:function(){try{if(this._shouldPostMessage()){var o={action:"infinite-loop",line:this._findAroundLineNumber()};parent.postMessage(JSON.stringify(o),"*")}else this._throwAnErrorToStopPen()}catch(t){this._throwAnErrorToStopPen()}},_shouldPostMessage:function(){return document.location.href.match(/boomerang/)},_throwAnErrorToStopPen:function(){throw"We found an infinite loop in your Pen.

效果还是挺不错的，你可以改变背景颜色等等定制。
