First detect if the browser can handle HTML 5 then use something like this:
$('input').each(function (i, item) {
if ($(item).attr('min') !== undefined && $(item).attr('max') !== undefined) {
var select = document.createElement("SELECT");
$(select).attr('name', $(item).attr('name'));
$(select).attr('id', $(item).attr('id'));
$(select).attr('disabled', $(item).attr('disabled'));
var step = 1;
if ($(item).attr('step') !== undefined) {
step = parseFloat($(item).attr('step'));
}
var min = parseFloat($(item).attr('min'));
var max = parseFloat($(item).attr('max'));
var selectedValue = $(item).attr('value');
for (var x = min; x <= max; x = x + step) {
var option = document.createElement("OPTION");
$(option).text(x).val(x);
if (x == selectedValue) { $(option).attr('selected', 'selected'); }
$(select).append(option);
};
$(item).after(select);
$(item).remove();
}
});
Since you can't use the input[type=range]
selector i had to go with the $(item).attr('min') && $(item).attr('min')
approach, this will get a little weird if you have other types of input controls with those two attributes.
