I'm trying to add an item into an empty array using .push inside loop then display it again but nothing is happening. Below is my current code:
$('.button').on('click', function(){
const canvasArray = [];
$('.box').each(function(){
var boxName = $(this).text();
canvasArray.push(boxName);
});
console.log(canvasArray);
});<div class="catalog">
<div class="box box-1">Red</div>
<div class="box box-2">Blue</div>
<div class="box box-3">Green</div>
<div class="box box-4">Yellow</div>
</div>
<div id="result"></div>In my console log, it returns something like this:
Array(4) [ "Red", "Blue", "Green", "Yellow" ]
0: "Red"
1: "Blue"
2: "Green"
3: "Yellow"
length: 4
I want to display the value of my canvasArray and append it to a DIV and I'm trying to do something like this:
$.each(canvasArray, function(index, value){
$("#result").append(index + ": " + value + '<br>');
});
but nothing is happening and no error in my console log. Any idea?
Your code works. Here it is. Perhaps you were unsure how to structure it all?
In this demo, the results div is populated upon a second button press - but you could alternately just move the $.each() code up into the first button's click handler (below the console.log, for example).
const canvasArray = [];
$('.button').on('click', function(){
$('.box').each(function(){
var boxName = $(this).text();
canvasArray.push(boxName);
});
console.log(canvasArray);
});
$('.button2').on('click', function(){
$.each(canvasArray, function(index, value){
$("#result").append(index + ": " + value + '<br>');
});
});#result{
position:fixed;
top: 0px;
left: 350px;
width: 200px;
height: 130px;
margin-top:20px;
background:wheat;
