What is causing my div exchange using .class to fail?

Struggling to convert this code from working with IDs to Classes.

The code reveals one Div while hiding another based on the onClick event.

Originally, it was straightforward because the div location was absolute.

In the classes version, I need to reveal the next instance of 'product-specs' depending on the DIV where the onClick occurred.

PLEASE NOTE: There are multiple instances of the same classes on the page. References to the classes must be specific to the closest instance of the class, based on the location of the clicked link.

HTML:

<div class="product-details">
    <area shape="rect" onClick="swap3('product-details','product-specs');">
</div>

<div class="product-specs">
    <p>Content</p>
</div>

Javascript:

function swap3(oldDivId, newDivId) {
    var oldDiv = document.getElementById(oldDivId);
    var newDiv = document.getElementById(newDivId);
    oldDiv.style.display = "none";
    newDiv.style.display = "block";
}

Now, I'll need to incorporate multiple instances of product details and product specs.

New HTML:

<div class="product-details">
    <area shape="rect" onClick="swap3('product-   details','product-specs');">
</div>

<div class="product-specs">
    <p>Content</p>
</div>


<div class="product-details">
    <area shape="rect" onClick="swap3('product-   details','product-specs');">
</div>
<div class="product-specs">
    <p>Content</p>
</div>

New Javascript:

????????

Answer №1

Note: (I provided a detailed explanation of the code before here, so please refer to that for context) Keep in mind that when your selector is a className, it will return an array of elements. Adjust the code accordingly and test it with the following changes:

function swap3(currentDivId ,oldDivId, newDivId) {
    var oldDiv = $(currentDivId).nextAll("div." + oldDivId);
    var newDiv = $(currentDivId).nextAll("div." + newDivId);
    $(oldDiv).each(function(){ $(this).css({"display" : "none"}); });
    $(newDiv).each(function(){ $(this).css({"display" : "block"}); });
}

Answer №2

If you're working with vanilla JavaScript, you might consider using the getElementsByClassName() method -- though keep in mind that it lacks support in Internet Explorer versions up to 8. To work around this limitation, you could opt for a specialized wrapper script like the one mentioned here, or lean on a library such as jQuery to handle cross-browser compatibility.

When utilizing jQuery, you can implement a function like this:

function swap(oldClassName, newClassName) {
    $("'." + oldClassName + "'").hide();
    $("'." + newClassName + "'").show();    
}

If you want to conceal the 'details' section and reveal the next section, which is likely to be 'specs', give this jQuery code a try. It links a click function to each 'product-details' section so that when triggered, it will hide that particular section and display its immediate sibling:

$(".product-details").click( function() {
    $(this).hide();
    $(this).next().show();
});

The opposite effect (hiding specs and showing details) can be an interesting challenge for you to figure out ;-)

Answer №4

Original:

function switchDivs(oldID, newID) {
    var old = document.getElementById(oldID);
    var newItem = document.getElementById(newID);
    old.style.display = "none";
    newItem.style.display = "block";
}

Using jQuery:

function switchDivs(oldID, newID) {
    var $old = $('#' + oldID);
    var $newItem = $('#' + newID);
    $old.hide();
    $newItem.show();
}

Applying jQuery Classes:

function switchDivs(oldClass, newClass) {
    var $old = $('.' + oldClass);
    var $newItem = $('.' + newClass);
    $old.hide();
    $newItem.show();
}

Answer №5

If you want to group your products together, one approach is to enclose each product in a div without any specific class or id. This can help organize them more effectively:

<div>    
    <div class="product-details">

        <area shape="rect" onClick="swap3('product-   
details','product-specs');">

    </div>

    <div class="product-specs">

        <p>Content</p>

    </div>

</div>

<div>
    <div class="product-details">

        <area shape="rect" onClick="swap3('product-   
details','product-specs');">

    </div>

    <div class="product-specs">

        <p>Content</p>

    </div>
</div>

By adding these extra wrapping divs, you can now use the parent element to pinpoint the product specs that need to be displayed. For instance, you can achieve this using jQuery:

$('.product-details').click(function() {
    // Locate the specs to display
    var $specs = $(this).siblings('.product-specs');
    // Hide any other specs
    $('.product-specs').not($specs).hide();
    // Show the desired specs
    $specs.show();
});

Give it a try and hopefully it will meet your needs!
