document.getElementById().style.transition 没有 return 任何值

Question

我有一个 ID 为 'he' 的 div 元素，其 css 属性为 position: fixed; 和 left: 0;

javascript:

    var dief = document.getElementById('he');

//this gets a random value within the dimensions of the page so that the object does not move
    var mh = Math.floor(Math.random() * window.innerHeight);
//this should set the transition to be mh/50, but it does not apply
    dief.style.transition = "transition: left "+mh/50+"s linear;";
//this sets the position 
    dief.style.left = mh+"px";

Answer 1

您不需要 'transition' 属性和样式属性中的分号。

未测试：

dief.style.transition = "left "+mh/50+"s linear";
