jQuery - jQuery .post() vs .get() Methods

The .get() and .post() methods in jQuery are used to send HTTP requests to a server and receive responses without reloading the page. Both are shortcuts built on top of jQuery AJAX, but they differ in how data is sent, how secure the request is and when each method should be used.

Purpose of .get() Method
The .get() method sends data to the server using the HTTP GET protocol. Data is appended to the URL as query parameters, making it visible in the browser address bar. It is mainly used to fetch data, such as loading lists, searching records or retrieving information that does not modify server data.

Purpose of .post() Method
The .post() method sends data using the HTTP POST protocol. Data is included in the request body instead of the URL, which keeps it hidden from the address bar. This method is commonly used for submitting forms, sending sensitive data and performing operations that change server-side data.

Key Differences in Data Handling
GET requests have size limitations because data is sent through the URL, while POST requests can send larger amounts of data. GET requests are often cached by browsers, but POST requests are not cached by default. This makes GET suitable for read-only operations and POST better for create or update operations.

Security Considerations
Data sent using .get() is exposed in URLs, browser history and server logs. This makes it unsuitable for sensitive information such as passwords or personal data. .post() is safer for such cases because the data is not displayed in the URL, although HTTPS is still required for real security.

Typical Use Cases
Use .get() when requesting data without changing server state, like loading content or filtering results. Use .post() when submitting data, saving records or performing actions that modify server data. Choosing the correct method improves performance, security and clarity of application behavior.
