If you want to get a random item from an array using JavaScript, then you can follow the below steps:
Step 1: Let’s say, I have an array of items and I want to show the user’s random item:
var items = [100,200,300,400,500];
Step 2: To get random item from array, I’ll create a function ‘random_item()’:
function random_item(arr)
{
var item = arr[Math.floor(Math.random() * arr.length)];
return item;
}
Step 3: I’ll call the random_item() function and pass the array as a parameter in it and print the result using alert box.
$random_item = random_item(items);
alert($random_item);
Here is the complete code:
function random_item(arr)
{
var item = arr[Math.floor(Math.random() * arr.length)];
return item;
}
var items = [100,200,300,400,500];
$random_item = random_item(items);
alert($random_item);
