Creating Your First Tampermonkey Script
Now that you have installed Tampermonkey, it’s time to create your first script. Here’s a step-by-step guide:
Creating a New Script
- Click on the Tampermonkey icon in the browser toolbar.
- Click on the “Create a new script” button.
- Choose a name for your script and select a namespace (optional).
- Click on the “Create” button to create the script.
Understanding the Script Editor
The script editor is where you write your Tampermonkey script. Here’s an overview of the editor:
- Toolbar: The toolbar provides access to various features, including the ability to save, load, and run scripts.
- Code editor: The code editor is where you write your script. It provides syntax highlighting, auto-completion, and other features to make coding easier.
- Console: The console displays output from your script, including errors and debug messages.
Writing Your First Script
Here’s an example of a simple Tampermonkey script that displays a message on the page:
“`javascript
// ==UserScript==
// @name My First Script
// @namespace http://tampermonkey.net/
// @version 0.1
// @description try to take over the world!
// @author You
// @match https://www.example.com
// @grant none
// ==/UserScript==
(function() {
‘use strict’;
alert(“Hello, world!”);
})();
“`
This script uses the alert function to display a message on the page. The @match directive specifies the URL of the page where the script should run.
Understanding Tampermonkey Script Structure
Tampermonkey scripts have a specific structure that includes metadata, functions, and variables. Here’s an overview:
Metadata
Metadata provides information about the script, including its name, version, and author. Here’s an example:
javascript
// ==UserScript==
// @name My Script
// @namespace http://tampermonkey.net/
// @version 0.1
// @description try to take over the world!
// @author You
// @match https://www.example.com
// @grant none
// ==/UserScript==
Functions
Functions are reusable blocks of code that perform a specific task. Here’s an example:
javascript
function greet(name) {
alert("Hello, " + name + "!");
}
Variables
Variables store values that can be used in the script. Here’s an example:
javascript
var name = "John";
Advanced Tampermonkey Scripting Techniques
Once you have mastered the basics of Tampermonkey scripting, you can move on to more advanced techniques, including:
DOM Manipulation
DOM manipulation involves modifying the structure and content of web pages. Here’s an example:
“`javascript
// Get the page title
var title = document.title;
// Set the page title
document.title = “New Title”;
“`
Event Handling
Event handling involves responding to events, such as clicks and keyboard input. Here’s an example:
javascript
// Add an event listener to the page
document.addEventListener("click", function() {
alert("You clicked the page!");
});
AJAX Requests
AJAX requests involve sending requests to servers and receiving responses. Here’s an example:
javascript
// Send a GET request to the server
var xhr = new XMLHttpRequest();
xhr.open("GET", "https://www.example.com", true);
xhr.onload = function() {
alert(xhr.responseText);
};
xhr.send();
