Show or conceal a class

Hello there!

I've been attempting to create a toggle effect using an anchor link with an "onclick" event to show and hide content. Despite my efforts with jQuery and JavaScript functions, I just can't seem to figure out the right approach. Here's what I have so far (my 8th attempt):

Here are the styles in styles.css:

.noPhones{
    display: none;
}

The JavaScript code in contacts.tpl:

{literal}
<script type="text/javascript">
function swapMyToggledDiv()
{
if(document.getElementById(".noPhones").style.display == "none")
{
document.getElementById(".noPhones").style.display = "block";
}
else
{
document.getElementById(".noPhones").style.display = "none";
}</script>
{/literal}

And finally, here's how the forms are structured in contacts.tpl:

        <tr><td>
            <h2><a href="#" onclick="swapMyToggledDiv()">Phone</a></h2>
        </td><td>
          // form inputs here
        </td></tr>

        // additional form input rows with class "noPhones", initially hidden

I am looking to have all the rows with the "noPhones" class hidden until the user clicks on the anchor link. Any assistance or guidance on this matter would be truly appreciated!

Thank you in advance for any help!

Answer №1

Using jQuery to toggle visibility is a breeze:

function toggleMyDiv()
{
    $( ".hideOnLoad" ).toggle();
}

You can enhance this functionality by assigning an ID to your link and triggering the action in the jQuery document ready function:

$( function() {
    $( "#toggler" ).click( function() {
        $( ".hideOnLoad" ).toggle();
    });
});

Answer №2

It's important to remember that using 

document.getElementById(".noPhones")
will not work.

In this case, you must use an id attribute instead of a class.

Answer №3

Jquery is incredibly user-friendly and efficient. I highly recommend using it as it simplifies coding tasks.

Here's a quick guide:

Step 1: Include Jquery

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>

Step 2: set the onclick to call a function "testFunction()"

Step 3: Define the function

<script type="text/javascript">
    function testFunction() {
    $('.noPhones').hide(); // or $('.noPhones').show();
    // The $('.noPhones') selector targets all elements with the class of "noPhones"
    // Use $('#id') to select an element by its ID
    }
</script>

If you want certain actions to occur upon page load, follow this example...

<script type="text/javascript">
    $(function(){ //define function here });
    // Anything within the function will be executed when the page loads.
</script>

I hope this explanation proves useful! jQuery is truly amazing.
