将Jquery Var附加到函数URL

Here I would like to append the variable arr_icao and dep_icao to the url

var arr_icao = document.getElementById("arr_icao").value;
var dep_icao = document.getElementById("dep_icao").value;

$.ajax({
    type: 'POST',
    url: "http://localhost/position/route_finder/" + arr_icao + dep_icao,
    success: function (data) {
        $(".route-results").html(data);
    }
});

You can use it like

var newUrl = "http://localhost/position/route_finder/" + arr_icao +"" + dep_icao;
$.ajax({
    type: 'POST',
    url: newUrl,
    success: function(data) {
        $(".route-results").html(data);
    }
});

change from

url: "http://localhost/position/route_finder/" + arr_icao + dep_icao,

to

url: "http://localhost/position/route_finder/" + arr_icao + "/" + dep_icao,

You can keep adding parameters to the end of your URLS using ?

if its a GET request

"http://localhost/position/route_finder/?arr_ica="+arr_icao+"&dep_icao="+dep_icao,

or if its a POST request

"http://localhost/position/route_finder/"+arr_icao+"/"+dep_icao

If route_finder is a function with the 2 arguments then u should use

"http://localhost/position/route_finder/" + arr_icao + "/" + dep_icao,

if You are going to get the data using GET method then use

"http://localhost/position/route_finder?arr_icao="+arr_icao+"&dep_icao="+dep_icao,

And as you have defined the method post you should go for

"http://localhost/position/route_finder/" + arr_icao + "/" + dep_icao,
