如何获得jQuery的无限重复功能？

Question

I currently have the following piece of code. When "true" is returned from tv.php the code seems to stop. How can I make this code check tv.php every 60 seconds, and repeat regardless of what TV.php returns? (I want the to refresh every time it detects "true", and keep checking every 60 seconds infinitely)

$(document).ready(function(){
    setInterval(function() {
        $.ajax({
            url: 'checktime.php',
            success: function(refresh){
                if($.trim(refresh) == "true"){
                    $('#tv').load('tv.php');
                }   
            }
        });
    }, 60000);

});

Try with:

    function ref(){
        $.ajax({
            url: 'checktime.php',
            success: function(refresh){
                if($.trim(refresh) == "true"){
                    $('#tv').load('tv.php', function(){
                         setTimeout(ref, 60000); // Do again after 60s
                    });
                }   
            }
        });
    }

    ref(); // First run

My guess is there is an exception when tv.php is being loaded. Check your console output for possible exceptions. You could also try adding a try/catch:

$(document).ready(function(){
  setInterval(function() {
    $.ajax({
        url: 'checktime.php',
        success: function(refresh){
            if($.trim(refresh) == "true"){
                try {
                   $('#tv').load('tv.php');
                } catch(err) {}
            }   
        }
    });
  }, 60000);
});
