item,index,array 不是函數嗎，為什么item會大于2，而且這個函數調用了嗎？總之就是看不懂這代碼，求大神幫忙<!DOCTYPE html><html><head><title>Array every() and some() Example</title></head><body><script> var numbers = [1,2,3,4,5,4,3,2,1]; var everyResult = numbers.every(function(item, index, array){ return (item > 2); }); alert(everyResult); //false var someResult = numbers.some(function(item, index, array){ return (item > 2); }); alert(someResult); //true</script></body></html>
javascript 中every（）方法沒看懂
