I have two radio buttons. When I click on one, the other should bee unchecked, and vice versa.

The code I've produced so far is not working:

<input type="radio" id="rbdemail" onclick="chekrbdclick()" checked="checked" />
<input type="radio" id="rbdsitelnk" onclick="chekrbdclick()" />

function chekrbdclick() 
{
  // How to manage here?
}

Reset to default 7

Simple, just use a 'name' property with the same value for both elements:

<html>
<body>

<form>
  <input type="radio" name="size" value="small" checked> Small
  <br>
  <input type="radio" name="size" value="large"> Large
</form> 

</body>
</html>

hope it helps

<form>
  <label>
    <input type="radio" name="size" value="small" checked> Small
  </label>
  <br>
  <label>
    <input type="radio" name="size" value="large"> Large
  </label>
</form>

Give them a name attribute with mon value like size, and it will work. For best practice, you can place your input tag inside a label tag, so that, even if your user clicks on the text beside the button (ie on "Small" or "Large"), the respective radio button gets selected.

The perfect answer is above answered ,but I wanna share you how it can work by javascript ,this is javascript work (not standard answer) ....

    <input type="radio" id="rbdemail" onclick="chekrbdclick(0)" checked="checked" value="Small" />Small<br>
    <input type="radio" id="rbdsitelnk" onclick="chekrbdclick(1)" value="Large" />Large
    <script>
    function chekrbdclick(n) 
    {
      var small = document.getElementById('rbdemail');
      var large = document.getElementById('rbdsitelnk');
     if(n === 0){  
      small.checked = true;  
      large.checked = false;
     }
     else {   
      small.checked = false;  
      large.checked = true;
     }
    }
    </script>
