Fix the forEach is not a function error in JavaScript

In this post we will give you information about Fix the forEach is not a function error in JavaScript. Hear we will give you detail about Fix the forEach is not a function error in JavaScriptAnd how to use it also give you demo for it if it is necessary.

we are going to learn about how to Fix the forEach is not a function error in JavaScript

When we use a Array.forEach() method on a value which is not an type array we will get the following error in our console.

Example:

const elements = document.getElementsByClassName("container");console.log(elements); // [div.container, div.container, div.container]elements.forEach(element =&gt; {});// Uncaught parent.forEach is not a function

In the above example, we are using the forEach() method on a HTML collection which looks like an array but it’s not an array.

To fix the error, convert the HTML collection to an array by using the spread operator and run the forEach() method on it.

Here is an example:

const elements = document.getElementsByClassName("container");[...elements].forEach(element =&gt; {   element.style.color = "green";});

or we can check if a given value is an type array or not before calling the forEach function.So that we can avoid runtime errors.

var arr = [1, 2, 3];if(Array.isArray(arr)){    arr.forEach(el =&gt; {       console.log(el);    });}

I want to share this posts with you because when i was working on native PHP and Ajax Post request(Specially AngularJS Post request) at that time i can't get Post value on form submit. That's why i would like to share you this post. I also want to tell you i was working on my Ubuntu 14.04. I did try lot but i can't get value.

At last find stuff to how to solve this issue, i did use "file_get_contents('php://input')" that way i could get POST value in json object and i also decode json value using "json_decode()". So let's try this way :

Example:

$post = file_get_contents('php://input');
$post = json_decode($post);
$sql = "INSERT INTO items (title) VALUES ('".$post->title."')";
$result = $mysqli->query($sql);
