Creating the Script
This code contains the script of the application. This code will copy an array value when the button is clicked. To do this just copy and write these block of codes as shown below inside the text editor and save it as script.js inside the js directory- var list1 = document.getElementById('list1');
- var array1 = [];
- var array2 = [];
- function arrayList1() {
- var data = '';
- if (array1.length > 0) {
- for (i = 0; i < array1.length; i++) {
- data += '<tr>';
- data += '<td>' + array1[i] + '</td>';
- data += '</tr>';
- }
- }
- list1.innerHTML = data;
- };
- function arrayList2() {
- var data = '';
- if (array2.length > 0) {
- for (var i = 0; i < array2.length; i++) {
- data += '<tr>';
- data += '<td>' + array2[i] + '</td>';
- data += '</tr>';
- }
- }
- list2.innerHTML = data;
- };
- function copyArray(btn){
- if(array1.length > 0){
- for (var i = 0; i < array1.length; i++) {
- array2.push(array1[i]);
- }
- arrayList2();
- }
- btn.setAttribute("disabled", "disabled");
- document.getElementById('clear').removeAttribute('disabled');
- }
- function clearAll(btn){
- array2=[];
- document.getElementById('list2').innerHTML = "";
- document.getElementById('copy').removeAttribute('disabled');
- btn.setAttribute("disabled", "disabled");
- }
- function insert() {
- var el = document.getElementById('name');
- var name = el.value;
- if (name) {
- array1.push(name.trim());
- el.value = '';
- }
- arrayList1();
- if (array2.length == 0) {
- document.getElementById('copy').removeAttribute('disabled');
- }
- };
