在此代码上的函数whatareyousingingpatrick(),上，每当调用该函数时应调用一个新元素并调用setinterval，但是似乎并没有使用新的original变量创建一个新的变量，就像一次又一次被解雇。 :)

最佳答案
我没有看完你所有的代码。但这至少可以解决部分问题：
setInterval("dis"+original+"();alert("+original+");", original+500);
应该：
setInterval(function(){
var func = 'dis' + original;
func();
alert(original); //for some reason
}, original+500);
关于javascript - 同时触发SetInterval，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/20591161/
