#1 Created at ... [Delete] [Delete and Lock User]

var arr = ['Swift', 'ANSI C', 'DirectX']

var ul = document.getElementById('test-list');

// 常规方法

for (li of ul.children) {

    if (arr.indexOf(li.innerText) >= 0) {

        ul.removeChild(li);

    }

}

// 魔术方法

Array.from(ul.children)

     .filter(child => arr.indexOf(child.innerText) >= 0)

     .forEach(child => ul.removeChild(child));

var arr = ['Swift', 'ANSI C', 'DirectX']

var ul = document.getElementById('test-list');

// 魔术方法

Array.from(ul.children)

     .filter(child => arr.indexOf(child.innerText) >= 0)

     .forEach(child => ul.removeChild(child));
