Array.includes(value,index) 方法用来判断一个数组是否包含一个指定的值,根据情况,如果包含则返回 true,否则返回 false。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 var array1 = [1, 2, 3]; console.log(array1.includes(2)); // expected output: true var pets = ["cat", "dog", "bat...
Array.prototype.toLocalString() 返回一个由所有数组元素组合而成的本地化后的字符串。遮蔽了原型链上的同名方法。 Array.prototype.indexO() 返回数组中第一个与指定值相等的元素的索引,如果找不到这样的元素,则返回 -1。 注意:indexOf 使用strict equality (===操作符基于同样的方法)进行判断 searchElement与...
Array.from()方法用于将两类对象转为真正的数组:类似数组的对象(array-like object)和可遍历(iterable)的对象(包括ES6新增的数据结构Set和Map)。 一个转换类数组对象到数组的一个示例: let list = document.querySelectorAll('ul.fancy li'); Array.from(list).forEach(function (li) { ...
