I want my code to get the checked radio button value when the user clicks the save button. I have the code laid out but I am unsure how to loop through the radio buttons since they don’t have a class id? Here’s what I have:

<html xmlns="http://www.w3.org/1999/xhtml">

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

<script>
saveButton.onclick = function() {       
    // Go through shirtColor rabio buttons to see which one is ticked
    for (var i = 0; i < shirtColor.length; i++) {
        if (.checked = true) {
            // Set shirtColor variable to selected color
            var shirtColor = .checked;

            // Only one value can be selected so we're done
            return;
        }
    }
};
</script>
</head>

<body>
<p>Shirt Color:
<input type="radio" name="shirtColor" id="red" value="red" />
Red
<input type="radio" name="shirtColor" id="green" value="green" />
Green
<input type="radio" name="shirtColor" id="blue" value="blue" /> 
Blue</p>
<p>
<input type="button" id="saveButton" value="Save">
</p>
</body>

    With plain Javascript you could do:

    saveButton.onclick = function() {       
    // Go through shirtColor rabio buttons to see which one is ticked
    var shirtColors = document.getElementsByName("shirtColor");
    for (var i = 0; i < shirtColors.length; i++) {
        var shirtColor = shirtColors[i];
        if (shirtColor.checked) {
            // Set shirtColor variable to selected color
            alert(shirtColor.value);

            // Only one value can be selected so we're done
            return;
        }
    }
};
