Question

function load_result()
{
    $.getJSON( "http://somesite.com/loadresult.php", function(data) {
        if( data == undefined || data == null )
        {
            console.log( "no data" );
            clearTimeout( lr_timeout );
            lr_timeout = setTimeout( "load_result()", 2000 );
            return;
        }
        insert_result_price( data );
        clearTimeout( lr_timeout );
        lr_timeout = setTimeout( "load_result()", 50 * ( Math.random() * 10 ) );

    } );
}

and lr_timeout is defined globally and the load_result function is kicked off initially in the document.ready function. The problem is that the function doesn’t always run. I’ll watch it in Firebug and I have another function that’s set on a setInterval that always works.

Ideas?

Answer 1

Is your other setTimeout function (the one that always works) also inside a $.getJSON? If so, does it call it on the same URL (http://somesite.com/loadresult.php in your example, but I’m sure it’s different in real life)?

It’s possible that http://somesite.com/loadresult.php is a flaky resource, and your inconsistent results are due to that resource, not setTimeout. Of course, if they’re both using that same resource, then that couldn’t be the problem.
