问题描述

如何让javascript在两个按钮之间随机选择点击?

How can I make javascript randomly choose between two buttons to click?

var $1Button = $('#1'),
    $2Button = $('#2');

function startQuiz(){
  $1Button.trigger('click');
}

推荐答案

处理这种情况的一种简单方法是将两个按钮放在一个数组中，然后在该数组中随机选择一个索引来触发点击.作为一个额外的好处，代码可以轻松扩展到两个以上的按钮.

An easy way to handle this situation is to place your two buttons in an array and pick a random index in that array to trigger the click. As an added bonus, the code will easily expand to more than two buttons.

var $buttons = [$('#1'), $('#2')];

function startQuiz(){
  var buttonIndex = Math.floor(Math.random() * $buttons.length)
  $buttons[buttonIndex].trigger('click');
}
