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(ithis.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.
