display:none not working in IE7

Situation:- I have created a RadioButton group. When a User selects a radio button depending upon his choice the content gets displayed and the other content is removed.

Problem:- The page is working fine in all browsers except IE7. I need a solution that runs in IE7 also.

Code:-

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>IE7 Bug display:none</title>
    <style>
        #entireContent, #div1, #div2{
            display:block;
        }
    </style>
    <script type="text/javascript">
        function displayDiv1(){
            document.getElementById('div1').setAttribute('style','display:&quot');
            document.getElementById('div2').setAttribute('style','display:none');

        }
        function displayDiv2(){
            document.getElementById('div1').setAttribute('style','display:none');
            document.getElementById('div2').setAttribute('style','display:&quot');  
        }
    </script>
</head>
<body>
    <div id="entireContent">
        <input type="radio" name="group" value="t1" onclick="displayDiv1()">TEST 1<br>
        <input type="radio" name="group" value="t2" onclick="displayDiv2()">TEST 2<br>
        <div id="div1">TEST 1</div>
        <div id="div2">TEST 2</div>
    </div>
</body>
</html>

Please help me to resolve this issue. Thanks in Advance.

Solution

You can try this instead:

To Display:

document.getElementById('element_id').style.display = 'block';

To Hide:

document.getElementById('element_id').style.display = 'none';

That should work.
