รหัสตัวอย่าง
ลบบางส่วนธาตุจากอาเรย์
var colors = ["red","blue","car","green"];
var carIndex = colors.indexOf("car");//get "car" index
//remove car from the colors array
colors.splice(carIndex, 1); // colors = ["red","blue","green"]ลบบางส่วนธาตุจากอาเรย์
var colors = ["red","blue","car","green"];
var carIndex = colors.indexOf("car");//get "car" index
//remove car from the colors array
colors.splice(carIndex, 1); // colors = ["red","blue","green"]ลบตารางคู่ลำดับส่วนประกอบจาวาสคริปต์
let value = 3
let arr = [1, 2, 3, 4, 5, 3]
arr = arr.filter(item => item !== value)
console.log(arr)
// [ 1, 2, 4, 5 ]js อาเรย์ลบเจาะจงธาตุ
var array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0];
var filtered = array.filter(function(value, index, arr){
return value > 5;
});
//filtered => [6, 7, 8, 9]
//array => [1, 2, 3, 4, 5, 6, 7, 8, 9, 0]ลบตารางคู่ลำดับส่วนประกอบจาวาสคริปต์
let value = 3
let arr = [1, 2, 3, 4, 5, 3]
arr = arr.filter(item => item !== value)
console.log(arr)
// [ 1, 2, 4, 5 ]ยังไงจะลบเฉพาะเรื่องธาตุจากอาเรย์อยู่ในจาวาสคริปต์
var arr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0]
newArr.splice(1,2)
//remove 1 element from index 2หน้าคล้ายกัน
