show message based on select box item chosen

I have a select box that the user can select 1-10. I want to show a special message if the user selects anything higher than 4 beside the select box. How would I go about doing this?

Thanks!

javascript

function validate(elem) {

var content = document.getElementById('content');

var value = elem.options[elem.selectedIndex].value;

if(value > 4){

content.innerHTML = "higher than 4";

}else{

content.innerHTML = "";

}

}


html

<select onChange="validate(this);">

<option value="0">Select an option</option>

<option value="1">1</option>

<option value="2">2</option>

<option value="3">3</option>

<option value="4">4</option>

<option value="5">5</option>

<option value="6">6</option>

<option value="7">7</option>

<option value="8">8</option>

<option value="9">9</option>

<option value="10">10</option>

</select><span id='content'></span>
