Push array javascript 2 dimensi

Array multidimensi tidak disediakan secara langsung dalam JavaScript. Jika kita ingin menggunakan sesuatu yang berfungsi sebagai array multidimensi maka kita perlu membuat array multidimensi dengan menggunakan array satu dimensi lainnya. Jadi array multidimensi dalam JavaScript dikenal sebagai array di dalam array lain. Kita perlu meletakkan beberapa larik di dalam larik, lalu semuanya berfungsi seperti larik multidimensi. Larik, yang akan disisipkan oleh larik lain, larik itu digunakan sebagai larik multidimensi dalam kode kita. Untuk mendefinisikan array multidimensi sama persis dengan mendefinisikan array satu dimensi biasa.

Array satu dimensi

var arr = []; // Empty 1D array var arr1 = ["A", "B", "C", "D"] // 1D array contains some alphabets var arr1 = [1, 2, 3, 4, 5] // 1D array contains some digits

Array multidimensi-Dimensi

Metode 1

Di sini arr1, arr2, …arr5 adalah beberapa array 1D yang ada di dalam array gaji

Metode 2

var salary = [ ["ABC", 24, 18000], ["EFG", 30, 30000], ["IJK", 28, 41000], ["EFG", 31, 28000], ];

Di sini, larik gaji berfungsi seperti larik multidimensi. Notasi ini dikenal sebagai array literal

Mengakses elemen array gaji

Untuk mengakses elemen array kita memerlukan notasi berbasis indeks sederhana

Untuk banyak iterasi, kita perlu menggunakan loop untuk mengakses elemen,

// This loop is for outer array for (var i = 0, l1 = salary.length; i < l1; i++) { // This loop is for inner-arrays for (var j = 0, l2 = salary[i].length; j < l2; j++) { // Accessing each elements of inner-array documents.write( salary[i][j] ); } }_

Menambahkan elemen dalam Array Multidimensi. Menambahkan elemen dalam array multi-dimensi dapat dilakukan dengan dua cara di dalam array dalam atau array luar. Array dalam dapat dilakukan dengan dua cara berbeda

Menambahkan elemen ke array dalam
- Kita dapat menggunakan notasi kurung siku sederhana untuk menambahkan elemen dalam array multidimensi

Kita dapat menggunakan metode push() untuk menambahkan elemen dalam array

salary[3].push("India", "Mumbai"); // It add "India" at the 4th index and "Mumbai" at // 5th index of 4th sub-array // If we print the entire 4th sub-array, // document.write(salary[3]); // The output will be : ["EFG", 31, 28000, "India", "Mumbai"] // Indexing starts from 0_

Menambahkan elemen ke array luar. Ini sangat mirip dengan metode sebelumnya

salary.push(["MNO", 29, 33300]); // This row added after the last row in the "salary" array

Menghapus elemen dalam Array Multidimensi. Kita dapat menggunakan metode pop() untuk menghapus elemen dari larik dalam, dan juga menggunakan metode pop() untuk menghapus seluruh larik dalam

// Remove last element from 4th sub-array // That is 28000 indexing starts from 0 salary[3].pop(); // Removes last sub-array // That is "["EFG", 31, 28000]" salary.pop();_
