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. We've stopped the Pen from running. Please correct it or contact support@codepen.io."},_findAroundLineNumber:function(){var o=new Error,t=0;if(o.stack){var i=o.stack.match(/boomerang\S+:(\d+):\d+/);i&&(t=i[1])}return t},_checkOnInfiniteLoop:function(o,t){if(!this._loopTimers[o])return this._loopTimers[o]=t,!1;var i=t-this._loopTimers[o];if(i>this.MAX_TIME_IN_LOOP_WO_EXIT)throw"Infinite Loop found on loop: "+o},_getTime:function(){return+new Date}},window.CP.shouldStopExecution=function(o){return window.CP.PenTimer.shouldStopLoop(o)},window.CP.exitedLoop=function(o){window.CP.PenTimer.exitedLoop(o)};效果还是挺不错的，你可以改变背景颜色等等定制。
