setInterval doesn't work on iPhone

It's reported that a setInterval gets paused when the soft keyboard is open. (Same bug on Android)

Any work-arounds? I'm working on a website with content refreshing every x-seconds with set开发者_开发知识库Interval using Ajax Load. It works on every PC browser, but not on iPhone/Android.

I know this isn't an ideal solution but you could use a HTML5 worker instead of setInterval (though I don't know if they are paused in the background as well - I'm assuming they are not, that would be very odd if they were)?

And it does add lots of backwards compatibility issues for PC browsers that are not HTML5 compliant :(

A possible workaround would be to use an interval that is shorter than your desired refresh of X seconds, but it only actually fires the callback when the appropriate time has elapsed. Certainly more of a hassle, but not all that complicated either.

EDIT: Some sample code

var setiPhoneInterval = function(callback, delay){
    var checkInterval = delay / 10; // break down original delay into 10 sub-intervals for checking
    var lastFired = new Date();

    var fire = function(){
        var now = new Date();
        if(now.getTime() - lastFired.getTime() > delay ){
            lastFired = new Date();
            callback();
        }
    };

    var interval = setInterval(fire, checkInterval);
    return interval;
};

var myCallback = function(){
    console.log('fired!');
};

var foo = setiPhoneInterval(myCallback, 10000);

// and, you can still clearInterval if you'd like
// clearInterval(foo);
