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. 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。
