Is there a JS equivalent to CSS text-transform: capitalize?_问答_开发者

I've got a hidden <section /> that is comprised of divs that contain content to be stuffed into a jQuery UI dialog. On document.ready I want to loop through those divs, take the id of each respective div, replace dashes with spaces, capitalize each word, and store that in a title variable. Then, I'm going use that in an object literal that gets put into my dialogs[] array开发者_如何学Go. Sounds simple, right?

Stripped down version of the HTML:

<section id="dialog-content" class="hidden">

    <div id="some-dialog">
        // awesome dialog content here
    </div>

    <div id="another-dialog">
        // awesome dialog content here
    </div>

    <div id="modal-dialog">
        // awesome dialog content here
    </div>

</section>

Stripped down version of the JavaScript:

var dialogs = [],
    $container = $("#dialog-content");
    $content = $container.find("> div");

$content.each(function (i) 
{       
    var $this = $(this),
        id = $this.attr("id"),
        title = id.replace(/\-/g, " ");

    console.log(title);

    dialogs[dialogs.length] = 
    { 
        trigger: $("#" + id + "-trigger"), 
        title: title, 
        content: $this.html() 
    };
});

BTW - I know I can use $.data() and add custom properties to my divs, but I really wanted as minimal of markup as possible, and I am curious about this specific possibility. So it's not so much my example, but the question at hand.

To re-iterate, the question is:

How can I capitalize each word in a variable via JavaScript, just like text-transform: capitalize; does in CSS?

You could simply write a function to do it. Here is a simple regex-based function:

function capitalize(text) {
    return text.replace(/\b\w/g , function(m){ return m.toUpperCase(); } );
}

This might be of help: Javascript: Capitalization of each Word in String.

Edit to include the content from the aforementioned linked answer:

The following will handle all Unicode letters, unlike any solution using \w, \b or [a-z] etc. Admittedly the regular expression is rather large. Character lists taken from Steve Levithan's excellent XRegExp library.
