AJAX is a development tool that works on top of HTTP. It is used for making client-side web applications, which means it can only be used for web pages and not mobile websites, or other applications.

When you are using AJAX, you have two to access the web server. Those options are: Get and Post.  Get is a request command to obtain information. Meanwhile the Post is a request to give more information to the server.

To get information To send information
Not able to send more than 1 request Able to send more than 1 request
Limited characters Can send longer instruction

Difference Between Ajax get and Post

What Is AJAX Get?

Get is simply an easy way to request some more information. It is intended to be used when you want to Get information from a web page. Browsers keep track of the response to a Get request. So if you make a similar Get request again, the browser will display the results of the cached page, rather than re-running the entire request. It makes the process become faster.

This isn’t a flaw in how browsers process Get requests; they are deliberately designed that way in order to make Get requests faster. Get is a simple way of Getting some basic information from the web server. It doesn’t change any data on the server, so it shouldn’t take much time to Get the information that you need.

What Is AJAX Post?

Post is used to Post or update information to a server. It is expected that when you send a Post request to a server, the server will change the information that you requested. The results from two Post requests might be different.

When you make the second call, the values that you received from the first Post call will process in a different way. They may have changed some of those values. Post calls are designed to always Get the server response that the server has sent, rather than use a copy of the response that the server has received previously.

How Are They Related?

Both Get and Post can contact the server and provide some information on clients’ screen. Some beginners make the mistake of when we have to use Get to request information from the server, and when we have to use Post. This is because Get is the easiest method to use to Get a lot of information.

Even though you’re only passing a very small amount of data, you aren’t limited by having to load a full web page at once. Some people may think about using Post requests on a small data where they need to pass more information than what Get allows.

Ajax get vs Post

To decide which one you have to use, you should not base your decision on how many characters you are passing into your Ajax request. You have to decide based on what your purpose is.

Get is the one you have to use when you ask for information from the server. While Post is the one you should use if you want to send information to the server.

If you are trying to fetch some data from the server, use Get. When your call is over time because of other processes you have made, you should add a time parameter to your following request.

When you want to write data to the server, use Post instead. You should use this criteria to choose between Get and Post when you are calling an Ajax server to retrieve some data from the server and when you are processing a form on your web page to Get some information.
