Create multiple buttons using array.protoype.forEach (javascript)

January 14, 2022

I am writing some code that will create multiple buttons based on the array given to the function. What I have done is that I used the array.prototype.forEach to test the function out by printing the contents of the array on the console. When that worked I tried to make some buttons but the buttons are not showing up on the page. I have tried adding document.body.appendChild(element); but all that did was give me errors. Is there a way to create multiple buttons based on an array of items using array.protoype.forEach?

This is my code:

var array = ["bill", "harry", "john", "timothy"];

array.forEach(element => 
  document.createElement(element)
//I tried adding document.body.appendChild(element); here but kept giving me errors

);

>Solution :

The first parameter you pass to document.createElement is a string that specifies the type of element to be created. Another problem in your code is that while the body of your function is multiline, you are not using {}, You can achieve your goal like this:

let array = ["bill", "harry", "john", "timothy"];

array.forEach(element=> { 
  let btn = document.createElement('button');
  btn.innerHTML = element;
  document.body.appendChild(btn);
});
