Getting state of a checkbox

I am having a problem getting the checked state of a checkbox after an onclick event. I have verified that the onclick event triggers but no matter how I try and check the state of the element (by name or by id) I am not seeing anything coming back. Below is a copy of the function I am currently trying to use to get it by the element ID and also the checkbox html code. The form name is addeval, if that is relevant.

<script type="text/javascript">
function RefreshScore()
{
If(document.getElementById("Section1Question1NAValue").checked)
      {
       alert("N/A is checked");
       }      
Else
      {      
      alert("N/A is NOT checked");
      }
}
</script>


<input name="Section1Question1NAValue" id="Section1Question1NAValue" type="checkbox" onClick="RefreshScore()">&nbsp;<span class="auto-style8">N/A
</span>

I don't know what you are trying to do but something this simple could suffice.

function RefreshScore(checked) {
  if ( checked )
     alert("N/A is checked");
  else
     alert("N/A is NOT checked");
}



<input name="Section1Question1NAValue" id="Section1Question1NAValue" type="checkbox" onClick="RefreshScore();" checked />

Open in new window


OR


function checkClick(cb) { 
  setTimeout(function() { 
    display("Clicked, new value = " + cb.checked); 
  }, 0); 
} 
<label><input type='checkbox' onchange=checkClick(this);'>Checkbox</label>

Open in new window


OR

<script type="text/javascript>
function RefreshScore(checkbox) 
{ 
    if (checkbox.checked) 
    { 
        alert("a"); 
    } 
} 
</script>

//markup
<input type="checkbox" <input name="Section1Question1NAValue" id="Section1Question1NAValue"  onclick="RefreshScore(this)" />

Open in new window

javascript is case sensitive.  So the If and Else keywords should be all in lower case.

Here your complete solution

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title></title>
    <script type="text/javascript">
        function RefreshScore(CtlID) {



            var result = CtlID.checked;
            if(result)
            {
                alert("N/A is checked");
               
            }
            else
            {
                alert("N/A is NOT checked");
            }
        }
</script>
</head>
<body>



<input id="Section1Question1NAValue" type="checkbox"  onclick="RefreshScore(this);"  /><span>N/A</span>


</body>
</html>

what I changed

1) if (previously it was If) and else  (previously it was Else)
2) Assign this
3) checking the value using this.

Let me know if it doesn't work.
