Get int value from a textfield

Question

This might be a very simple quesion. But I simply haven't been able to find the answer googling around.

I was wondering if there was a way that I could get the int value of a textfield instead of just the value.

Html:

<input id="Price" type="number" value="" placeholder="Price" />

JavaScript:

var oCar = 
{
    "Price": $('#Price').val()
}

Let's fx. say that I then add a speed property to the car. And later, I would then like to call it in an animate function like = "oCar.Speed".

$(".Car").animate({
//some animation
}, oCar.Speed, function() {

});

Then it's wouldn't work since the speed would be a string.

I just skimmed your question, but are you looking for `parseInt(...,10)` or `parseFloat(...)`? — Zeta, Oct 16 '13 at 12:02

@BlazingCoder That's a question about why `val()` sometimes returns `number` instead of `string`... — Johan, Oct 16 '13 at 12:04
@PaulS. Oh yeah, of course it does. Silly me :D Why do they let it work with the other common operators then? Just stop it working for all of them to avoid confusion. — Reinstate Monica Cellio, Oct 16 '13 at 12:12
@Archer this is because _String_ operators will shadow _Number_ operators (in _JavaScript_). String has no such operator `*`, `-` or `/` so it's only `+` you will see this happen with. — Paul S., Oct 16 '13 at 12:17
@PaulS That's exactly my point. Concatenation obviously makes perfect sense, but allowing the other 3 operators to work is just crazy. — Reinstate Monica Cellio, Oct 16 '13 at 12:18

Have you tried?

$(".Car").animate({
//some animation
}, parseInt(oCar.Speed,10), function() {

});

All HTMLInputElements will have a String for value, you could try using valueAsNumber, but I would not rely on this for now for compatibility reasons. Instead, cast the String to Number in your favourite way. For example; using a bitwise OR 0 to call JavaScript's internal ToInt32 (as described in the spec).

var oCar = {
    "Price": $('#Price').val() | 0
};
