How to set text in the google search box using Tampermonkey?

When using Tampermonkey, you can automate the process of filling specific text into the Google search box by writing a JavaScript script. This feature is useful for various purposes, such as testing or quickly searching for fixed keywords.

Step 1: Create a New Script

First, create a new user script in the Tampermonkey extension. Click on the browser extension icon and select 'Add New Script'.

Step 2: Write the Script

Next, write the following JavaScript code in the script editor:

javascript
// ==UserScript==
// @name         Google Search Autofill
// @namespace    http://tampermonkey.net/
// @version      0.1
// @description  try to take over the world!
// @author       You
// @match        https://www.google.com/*
// @grant        none
// ==/UserScript==

(function() {
    'use strict';

    // Listen for page load completion
    window.addEventListener('load', function() {
        // Select the Google search box
        var searchInput = document.querySelector('input[name="q"]');

        // Check if the search box exists
        if (searchInput) {
            // Set the search box value
            searchInput.value = "Tampermonkey";
        }
    });
})();

This script's primary function is to locate the Google search input box (with name attribute typically "q") after the page loads and set its value to "Tampermonkey".

Step 3: Save and Test

After saving the script, open a new Google search page, and you should see the search box automatically filled with "Tampermonkey".

Important Notes

• Ensure the script runs on the correct URL (as indicated by the @match tag in the code above).
• Given that Google may update its page structure, if the script stops working unexpectedly, you may need to check and update the selectors or other logic.

By doing this, you can modify the script as needed to automatically set different text in the Google search box or perform other operations.
