How to get the values of the slider bootstrap to hidden iputs?
At time of writing it's a bit flaky but you can make it work:
1/ Make sure you specify an empty range starting "value[0]". Unless you do this its internal value field becomes undefined e.g.
$('#setBidDialogSlider').slider({ value: [0], max: max, step: 0.2, formater: function(v) { return v.toFixed(2)+"BTC" } });
2/ Now finally you can catch the value in the event
$('#setBidDialogSlider').slider().on('slide', function(ev) {
$scope.dialog.order_value = ev.value*$scope.dialog.price;
});
