I try to use html5 element, which is
<input type='range' step='1' min='-300' max='-1' />
It is supposed to be a slider. It works in Chrome. But it does not work in Firefox8. I checked that in "html5test.com", it says firefox 8 partially supports the "range" type. It supports "min" and "max" attribute, but not "step" attribute. Then I erase the "step" attribute, like
<input type='range' min='-300' max='-1' />
Why it still does not work?
Is any way to let it work?
