No need to use regex here...

$('div').filter(function(){ 
    return this.id && !isNaN(this.id) && this.id % 1===0;
});

isNaN(123)     // false
isNaN('123')   // false
isNaN('foo')   // true
isNaN('10px')  // true

You can use filter(). The equivalent of [id^=integer] would be :

$('div').filter(function(){
    return this.id.match(/^\d/);
})

Only integer would be :

$('div').filter(function(){
    return this.id.match(/^\d+$/);
})
