Jquery load function params

#1 
$( "#result" ).load( "ajax/test.html" );

How can I pass some parameters using the links above to check whether to allow access or not and then return response lastly check for response.

#2

The parameter after the page you’re wanting to load is is a data object that contains the information you want to check. That data is given to the parameter 1 page which returns a response.
After that parameter is a function that receives the response.

See https://api.jquery.com/load/ for details and an example.

#3

How do I check for that data?

#4

The documentation page says:
The POST method is used if data is provided as an object; otherwise, GET is assumed.

The page that you load receives the data as a POST method.

How that page checks for data though has nothing to do with JavaScript, but frequently people use a server-side solution such as PHP to do things like that.

I recommend that you make further enquiries about checking for POST data in our PHP forum, which is one of the popular server-side solutions that are commonly used.
