Other option for li elements in place of the outdated value attribute

Currently, I am developing a web application using HTML 5, CSS, and JQuery. One of the features I am working on involves displaying page links in an unordered list (ul), where each li element contains the page link. The list is generated dynamically using jQuery.

I would like to show only the page name in the link elements while still retaining the full link path. For example, "http://www.foo.com/xyz/contactus" should be displayed as "contactus," but the li element should have access to the full link path. Ideally, I could accomplish this with the value attribute of the li element, setting it up as follows:

var ul = $('<ul/>').attr('id', 'linkList');
for (var i = 0; i < linksOnPage.length; i++)
{
    var pgName = linksOnPage[i].toString().slice(steps[i].toString().lastIndexOf('/') + 1);

    // Create list element and append content
    var li = $('<li/>').text(pgName);
    li.attr('value', linksOnPage[i].toString());

    ul.append(li);
}

This code snippet would result in a list similar to:

<ul>
    <li value="http://www.foo.com/xyz/contactus">contactus</li>
    ...
</ul>

Unfortunately, the value attribute of li has been deprecated since HTML 4.01. This raises questions about why this decision was made, considering its usefulness.

Considering this dilemma, I seek advice on how to proceed. One option is to overlook the deprecation and utilize the value attribute anyway since most major browsers still support it. However, I am hesitant to use a deprecated feature and find it somewhat unsettling.

Do you have any suggestions on how I should tackle this issue?

Answer №1

Transform from:

<li value="http://www.foo.com/xyz/contactus">contactus</li>

To:

<li data-value="http://www.foo.com/xyz/contactus">contactus</li>

The usage of the data-* pattern represents the latest HTML5 method of storing values within DOM elements.

You can retrieve the values using one of these two methods:

$('#li-Id').data('value');
$('#li-Id').attr('data-value');

You may refer to John Resig's blog post for more information on these attributes.

For jQuery, check out the data function

Answer №2

To easily include custom data in your HTML, you can utilize the data attribute by following this guide: introduction; comprehensive tutorial; specification:

<li data-path="http://www.foo.com/xyz/contactus">contactus</li>

An added benefit is that jQuery conveniently recognizes and reveals the values of these attributes using the .data method.

Answer №3

Despite being deprecated, the `value` attribute can still be utilized and accessed with JavaScript. The only thing you're sacrificing is validation status!

Alternatively, you could opt to use `data-*` attributes or directly map values to DOM elements - especially since this markup is being generated at runtime. You have the option to add a property like so (Javascript's flexibility can be both advantageous and troublesome):

li.someLinkPath = 'some url here';
//and in the click handler you could access this as
this.someLinkPath;

However, if your goal is navigation, why not simply use an anchor tag with an href attribute?
