Reset form on onclick function

by

If you want to have a reset button you have to include a reset input in the form:

<input type="reset" value="Reset!">

This element resets all form values to default values.

In your example 

<input type="button" onclick="" value="Neka bud"> - <input type="submit" value="Godkänn bud" />
<input type="reset" value="Reset!">
</form>
