I have this situation

```
<input type="radio" id="radio1" onclick="clickRadio1()" />Click Radio1
<input type="radio" id="radio2" onclick="clickRadio2()" />Click Radio2 to activate Radio1 click
<script type="text/javascript">
    <!--
    function clickRadio1(){
        return false;
    }

    function clickRadio2(){
        if(document.getElementById("radio1").click===false){
            alert("False");
        }else{
            alert("True");
        }
    }

    // -->
</script>

```

When I click "radio2" why I always get alert "True". Can someone explain why? Thank you very much.
