Sending one AJAX request at a time from a loop

You want something like this. I haven’t tested it, but hopefully you should get the idea.

var dates = []; //<-- Contains a list of dates for the coming week 
var baseUrl = "http://www.someserver.com";
var storedChannels = [1,2,3,4,5,6,7,8,9,10,45,23,56,34,23,67,23,567,234,67,345,465,67,34];

function ProcessNext(ch, d) {
    if (d < 7) {
        d++;
    } else {
        d=0;
        if (ch < storedChannels.length) {
            ch++;
        } else {
            return;
        }
    }

    var channel = storedChannels[ch];
    var currentDate = dates[d];
    ajax({    
        url: baseUrl+"?ch="+channel+"&dt=currentDate"+,
        complete: function(res) {
            CMLocalStore.setString('ch' + ch + "_" + scheduleDay, res);
            ProcessNext(ch, d);
            },
    });
}

ProcessNext(0, 0);
