Using Ajax for asynchronous communication involves utilizing the $.get() method, which is commonly used within callback functions like this:
$.get('http://example.com', function(result) {
console.log(result);
})
There is a question regarding the 'result' parameter. Where does this parameter named 'result' originate from? Can any name be assigned to it, and can additional arguments be included in the function? And if so, how should they be managed?
When creating a function, you have the freedom to choose any names for the parameters as long as they are valid identifiers:
function bar(x, y, z) { }
Upon calling the function, the arguments are then passed to those specific parameters in the order they were provided:
bar(4, 5, 6);
The process is identical for:
function(response) { console.log(response); }
The only distinction is that this function is invoked by code created by another individual (a part of the jQuery library).
Referencing the documentation will provide insight into what arguments are transferred:
success
Type: Function( PlainObjectdata, StringtextStatus, jqXHRjqXHR)
A callback function that executes upon request success. This is mandatory if dataType is specified, but you can utilize null or jQuery.noop temporarily.
Once the query is successful, a callback function will be triggered by jQuery passing the data as the first argument, followed by textStatus and jqXHR as subsequent arguments. For further information, please refer to the documentation available at https://api.jquery.com/jQuery.get/
