HTML 5 input type="number" element for floating point numbers on Chrome
I need to have users enter floating point numbers, so I use the following element:
<input type="number" name="my_number" placeholder="Enter number"/>
Works great on Firefox, but Chrome complains that the number is not an integer when I try to enter a decimal. That's a problem for my case. If I enter a step attribute, then Chrome allows the floating point number:
<input type="number" name="my_number" placeholder="Enter number" step="0.1"/>
But then the problem is 0.15 can't be entered... The step doesn't appear to suit my needs. The W3C spec mentions floating-point numbers throughout the attributes of input type="number".
How do I get Chrome to accept floating point numbers without the step attribute?
Answer
Try <input type="number" step="any" />
It won't have validation problems and the arrows will have step of "1"
Constraint validation: When the element has an allowed value step, and the result of applying the algorithm to convert a string to a number to the string given by the element's value is a number, and that number subtracted from the step base is not an integral multiple of the allowed value step, the element is suffering from a step mismatch.
The following range control only accepts values in the range 0..1, and allows 256 steps in that range:
<input name=opacity type=range min=0 max=1 step=0.00392156863>The following control allows any time in the day to be selected, with any accuracy (e.g. thousandth-of-a-second accuracy or more):
<input name=favtime type=time step=any>Normally, time controls are limited to an accuracy of one minute.
