HTML/CSS/JS Want to colour group of objects and then re-colour one of them?

Question

Basically i have 6 labels acting as buttons. When they are clicked on, they change from white to blue. As you click on another label, the previously blue label turns to white again and the currently click label turns to blue.

At the moment the code below sets them all to white but then doesnt appear to colour the newly clicked label to blue. However if i comment out the line:

document.getElementsByTagName('label').style.backgroundColor = '#fff';

Then each label clicked on turns to blue, but it remains blue when i click on a new label. So what i need to know is how to set the label class background to white, but then to turn the background of the recently clicked label to blue.

The result should be each time only the most recently clicked label background should be blue and the others white.

Thanks in advance

<script = "text\javascript">
        function toggle(label) {
            document.getElementById('one').style.display = 'block';
            document.getElementsByTagName('label').style.backgroundColor = '#fff';
            document.getElementById(label).style.color = 'rgb(54, 95, 145)';
            document.getElementById(label).style.backgroundColor = 'rgb(193,203,225)';
        }

    </script>

    <label id='Label6' class='button' onmousedown = 'toggle("Label6")'>Personal Details</label>
    <label id='Label1' class='button' onmousedown = 'toggle("Label1")'>Education</label>
    <label id='Label2' class='button' onmousedown = 'toggle("Label2")'>Achievements</label>
    <label id='Label3' class='button' onmousedown = 'toggle("Label3")'>Work Experience  </label>
    <label id='Label5' class='button' onmousedown = 'toggle("Label5")'>IT Skills</label>
    <label id='Label4' class='button' onmousedown = 'toggle("Label4")'>Languages</label>

Answer 1

Jquery really shines here. I would higly recommend using it

You can do something like

$("label").onclick(function() {
    $("label[id=^label]").css('backgroundcolor', 'white');
    $(this).css('backgroundcolor', 'blue');
});

PS: I haven't tested the code

Answer 2

The line you've highlighted is incorrect. This call:

document.getElementsByTagName('label');

Returns an array of elements, the array doesn't have the property style. You need to loop through the results:

var els = document.getElementsByTagName('label');
for (var i=0; i<els.length; i++) {
    els[i].style.backgroundColor = '#fff';
}

Alternatively, use jQuery like Mahesh suggests.
