                            ## javascript操作元素class的幾種方法
1. classList.add()，添加class
	classList.remove()，移除class
    ```
    var test = document.getElementById("test");
    test.onmouseover = function(){
        this.classList.add('animated')  //添加, 并且分步添加
        this.classList.add('shake');
    }
    test.onmouseout = function(){
        this.classList.remove('shake');  //移除

    ```
2. classList.toggle()，切換class
	示例：點擊切換屬性名
    ```
    toggle.onclick =()=>{
        if(parent.className == "none"){
            parent.className = "show";
        }else{
            parent.className = "none";
        }
        // parent.classList.toggle("none");
    }
    ```
3. className = " "
	該方法直接更改class名稱，會導致class全部發生改變
