嗨,我无法按顺序执行 javascript。事件是如何触发的。即使语句是按顺序放置的,执行也很疯狂。
我需要从 6..to..0 的倒计时数字,然后在 Div 标签中显示随机字符串

function getRandomArbitrary(min, max) { //function to pick question randomly based on math calculations
var temp = Math.floor(Math.random() * (max - min) + min)
return (temp > max) ? getRandomArbitrary(min,max): temp;

function questions(){ //returns the Question pattern
