使用$ .ajax定位某个PHP函数

Question

Hey guys I have a scenario,

I want to use the ajax $.get method to target a certain PHP function in a separate PHP file. I am not too sure about the syntax.

The Javascript

function all(){

    $.get({
    url: "functions.php  THEN GET A CERTAIN FUNCTION  ",
    success:  function success(data){   paint(data) },
    dataType: "html"
    });


});

function.php

 <?php

function helloWorld(){

echo "Hello World";

};

    function helloMars(){

echo "Hello Mars";

};

Any help greatly appreciated

Pass a variable in the data attribute or URL query string, and in your PHP script, choose a function based on that variable.

$.get({
   url: "functions.php",
   data: { "vname": "something" },
   success:  function success(data){   paint(data) },
   dataType: "html"
});

PHP:

if ($_GET["vname"] == "something") {
   helloWorld();
} else {
   helloMars();
}
