Question

我有两个数组：

<html>
<?php
    // declare connection variables
    $host = "localhost";
    $username = "root";
    $password = "";
    $dbname = "tsdb";
    $socket = "/Applications/XAMPP/xamppfiles/var/mysql/mysql.sock";

    // DB Connect
    $mysqli = new MySQLi($host, $username, $password, $dbname, ini_get('mysqli.default_port'), $socket) or die ('Error : ('. $mysqli->connect_errno .') '. $mysqli->connect_error);

    // get URL record 'id'
    $id = $_GET['id'];

    // get result of record from 'id'
    $query = "SELECT * FROM models WHERE id =$id";
    $result = $mysqli->query($query);
    $row = $result->fetch_array();
    $result->free();
    ?>

    <!-- vertical table for record edit -->

如何获得这样的数组：

var firstArr = [1,2,3,4,5];
var secondArr = [2,3];

我想使用一个解决方案，当数组的元素是具有多个属性的对象时，可以使用该解决方案。

Answer 1

使用filter：

filter()方法创建一个包含所有传递元素的新数组由提供的函数实现的测试。

例如：

firstArr.filter(function(item){ 
    return secondArr.indexOf(item) === -1; 
});

Answer 2

您可以使用此功能删除项目。

function removeA(arr) {
    var what, a = arguments, L = a.length, ax;
    while (L > 1 && arr.length) {
        what = a[--L];
        while ((ax= arr.indexOf(what)) !== -1) {
            arr.splice(ax, 1);
        }
    }
    return arr;
}
var ary = ['three', 'seven', 'eleven'];
removeA(ary, 'seven');

根据另一个数组从数组中删除项目
