javascript - this.class vs. this.getAttribute('class') -


i have radio button, , when pressed function called, accepts class of button argument. this:

<input class="myclass" type="radio" name="name" value="x" checked="true" onclick="myfunction(this.value, this.getattribute('class'))"></input>

notice in onclick, have this.getattribute('class') instead of this.class. tried using this.class kept getting undefined. this.class not acceptable thing do? have used this.id elsewhere in code works fine, reason need use getattribute when want reference class.

so asking difference between this.class , this.getattribute('class')?

use classname current value of class attribute. think reason behind because class reserved word.
