jquery

问题 I'm trying to make a text field so that if there's a number 153.254, that becomes 153.25. And if the field contains 154.2, an extra 0 is added to fill two spots after decimal; 154.20. toFixed() works great but I don't want the number rounded.

To understand what im talking about if you dont know, try the following.

问题 I'm trying to pass a Javascript array to my Django views. This works, but I would like to manipulate that data and display it in a separate url. So I have a products page, where you select items.
