javascript foreach element code example
Example 1: javascript foreach
const avengers = ['thor', 'captain america', 'hulk'];
avengers.forEach((item, index)=>{
console.log(index, item)
})
Example 2: for each js
const fruits = ['mango', 'papaya', 'pineapple', 'apple'];
// Iterate over fruits below
// Normal way
fruits.forEach(function(fruit){
console.log('I want to eat a ' + fruit)
});
Example 3: js for each item do
let array = ['Item 1', 'Item 2', 'Item 3'];
array.forEach(item => {
console.log(item); // Logs each 'Item #'
});
Example 4: javascript .foreach
let colors = ['red', 'blue', 'green'];
// idx and sourceArr optional; sourceArr == colors
colors.forEach(function(color, idx, sourceArr) {
console.log(color, idx, sourceArr)
});
// Output:
// red 0 ['red', 'blue', 'green']
// blue 1 ['red', 'blue', 'green']
// green 2 ['red', 'blue', 'green']
Example 5: what is foreach method in javascript
var arr = [1, 2, 3, 4, 5, 6];
//var sum = 0;
arr.forEach(function (value, index, array){ // Built in method
//sum += value;
console.log(value, index, array);
})
//console.log(sum); // We can print sum of all Array element (if those are numbers)
// function forEach(arr, cb){ // How forEach() method works
// for (var i = 0; i<arr.length; i++){
// cb(arr[i], i, arr);
// }
// }
// var sum = 0;
// forEach(arr, function (value, index, arr){
// console.log(value, index, arr);
// sum += value;
// })
// console.log(sum);
Example 6: foreach js
// result.params.detail = {
// "status": true,
// "message": "",
// "params": {
// "pay_credit_remain": 115,
// "month_expiry": "15",
// "detail": [
// {
// "credit": "70",
// "create_date": "2020-10-16",
// "expiry_date": "2022-01-16"
// },
// {
// "credit": "45",
// "create_date": "2020-10-17",
// "expiry_date": "2022-01-17"
// }
// ]
// }
//}
detail = "<ul>";
result.params.detail.forEach((val) => {
detail = detail + sprintf(lang.pay_credit_detail, val.credit, val.expiry_date);
});
detail += "</ul>";
$('#pay_credit_remain').html(detail);
