从数组中删除第一个元素并返回数组减去第一个元素

Question

var myarray = ["item 1", "item 2", "item 3", "item 4"];

//removes the first element of the array, and returns that element.
alert(myarray.shift());
//alerts "item 1"

//removes the last element of the array, and returns that element.
alert(myarray.pop());
//alerts "item 4"

1. 如何删除第一个数组但返回数组减去第一个元素
2. 在我的例子中,"item 2", "item 3", "item 4"当我删除第一个元素时,我应该得到

Answer 1

这应该删除第一个元素,然后你可以返回剩余的:

var myarray = ["item 1", "item 2", "item 3", "item 4"];
    
myarray.shift();
alert(myarray);

正如其他人所建议的那样,你也可以使用slice(1);

var myarray = ["item 1", "item 2", "item 3", "item 4"];
  
alert(myarray.slice(1));

Answer 2

为什么不使用 ES6？

 var myarray = ["item 1", "item 2", "item 3", "item 4"];
 const [, ...rest] = myarray;
 console.log(rest)

Answer 3

尝试这个

    var myarray = ["item 1", "item 2", "item 3", "item 4"];

    //removes the first element of the array, and returns that element apart from item 1.
    myarray.shift(); 
    console.log(myarray); 

Answer 4

array = [1,2,3,4,5,6,7,8,9];

array2 = array.slice(1,array.length); //arrayExceptfirstValue

console.log(array2);

我浏览了所有值得注意的答案。我指出了一个不同的答案。这个对我有用。我希望它能帮助你

array.slice(1,array.length)
