我有一个快速问题，我在我的代码中有一个随机函数，我希望随机函数随机化9个数字，并根据返回的数字显示数字快乐的面孔在我的HTML。使用JavaScript显示随机元素数
我的第一个问题是如何连接功能与我的快乐的面孔，第二个是，我应该有我的html所有九个快乐的面孔，或者我应该只有一个，并生成其他（取决于动态的。现在我有一个显示：在CSS上没有，我只是注释掉，所以你们可以看到它。
我添加一些代码在这里
'use strict';
$(document).ready(init);
var globalNum;
function init(){
\t $('.number').click(clickNum);
\t console.log('hello from jQuery!');
}
function getRandomInt(min, max) {
return Math.floor(Math.random() * (max - min + 1) + min);
}
console.log(getRandomInt(1,9));
function clickNum(){
\t var num = $(this).text();
\t console.log(num)
\t // addNumToDisplay(num);
}
// function displayNum(num){
// \t globalNum =
// \t var currentNumber = $('.number').text(num);
// \t console.log(currentNumber);
// }* {
\t /*outline: 2px solid red;*/
}

你应该重新评估'的（我;我<= getRandomInt（1,9）;我++）'有无尽的循环写在它上面:) – DelightedD0D
感谢b3da，临屋区t就是我在找的东西。 – Lucky500
@ Lucky500你不应该像这样在for循环的条件下调用函数。首先获取值，然后使用值 – DelightedD0D
