Question

I am trying to create a function that upon each call it chooses the next variable in an array.

var nexttest=['abc','def','ghi'];
function nexttest() {
 if (nexttest = 'abc') {
  $('#result').load('url1.html');
 }
 else if (nexttest = 'def') {
  $('#result').load('url2.html');
 }
 else {
  $('#result').load('url3.html');
 }
}

Is there a way to make nexttest() use abc the first time, def the second time, and ghi the third time.

Answer 1

I’d do it more like

var tester = function(){
    var i = 0;
    var tests = ['abc','def','ghi'];
    this.nexttest = function() {
        if (tests[i] == 'abc') {$('#result').load('url1.html');}
        else if (tests[i] == 'def') {$('#result').load('url2.html'); }
        else { $('#result').load('url3.html');}        
        i++;
    };
}

var testing = new tester();

testing.nexttest();
testing.nexttest();
testing.nexttest();
testing.nexttest();
