.data() and 64 bit integer

I just fixed a bug where my ID, which is a 64 bit integer, would be truncated to a 32 bit integer. I'm aware of this limitation in javascript, but it's still quite a nasty bug to find. Perhaps some warning or to return it as a string would be safer approach.


.data('userid') -> 2820496456973446000
.attr('data-userid') -> "2820496456973446118"

Javascript itself only supports about a 48-bit integer since it's the mantissa of a 64-bit floating point number. That's not something under the control of jQuery. Get the attribute as a string rather than using .data().
