count button in javascript

To count the number of buttons on a webpage using JavaScript, you can follow these steps:

1. Get all the buttons on the page using the querySelectorAll() method and passing the CSS selector for buttons as an argument. For example:

   index.tsx
   var buttons = document.querySelectorAll('button');
   51 chars
   2 lines

2. Retrieve the length of the buttons array to get the total count of buttons.

   index.tsx
   var count = buttons.length;
   28 chars
   2 lines

Here's an example of a complete JavaScript code snippet that counts the number of buttons on a webpage:

index.tsx
var buttons = document.querySelectorAll('button');
var count = buttons.length;

console.log("The number of buttons on the page is: " + count);
143 chars
5 lines

This code selects all <button> elements on the page and stores them in the buttons variable. Then, it retrieves the length of this collection using the length property and stores it in the count variable. Finally, it logs the count to the console.

Feel free to modify this code to suit your specific needs.
