How to do Initial Caps With Javascript/jQuery

Question

I have a Dynamic Breadcrumb set up with JavaScript. All I want is to do Initial Caps for each word.

Example: Home > Some > Page

Currently I have them all converted to lowercase and have removed all - from the strings in pages that have multiple words. I just need to convert the string to Initial Caps. Here is my code that I have working so far:

var path = "",
    href = document.location.href,
    domain =  href.match(/:\/\/(.[^/]+)/)[1],
    replacedomain = 'http://' + domain + '/',
    s = href.replace(/-/gi, " ").split("/"),
    lastElement = document.location.href.split('/').splice(-1,1);



for (var i = 2; i < (s.length - 1); i++) {
    path += "<a class='bc' href=\"" + href.substring(0, href.indexOf("/" + s[i]) + s[i].length + 1) + "/\">" + s[i] + "</a> >  ";

    if (i > 0) { 
       breadcrumb = path;  
    }
}


i = s.length - 1;
breadcrumb += "<span>" + s[i] + "</span>";


var breadcrumbl = breadcrumb.toLowerCase(),
    domain =  breadcrumbl.match(/:\/\/(.[^/]+)/)[1],
    breadcrumb2 = breadcrumbl.replace(domain, "").replace(domain, ""),
    breadcrumbs = breadcrumb2,
    url = '<a href="/">Home</a>' + breadcrumbs;

document.getElementById('breadcrumb1').innerHTML=url;

I think the solution is with a regular expression but I'm not good at writing them and I'm having a hard time with the concept. Also if anyone thinks this script can be optimized further your feedback is welcome. I'll will make variable names more semantic for production.

Answer 1

You could use css:

span.breadcrump {
    text-transform: capitalize;
}

Answer 2

I recently wrote this helper method to do this for me:

function autocase ( text ) {
    return text.replace(/(&)?([a-z])([a-z]{2,})(;)?/ig,function ( all, prefix, letter, word, suffix ) {
        if (prefix && suffix) {
            return all;
        }

        return letter.toUpperCase() + word.toLowerCase();
    });
}

It takes into account things such as ™

Edit: To use this method, simply pass it a string, and it will return the string auto cased. It does not work on html strings.

//...
document.getElementById('breadcrumb1').innerHTML=url;
function autocase ( text ) {
    return text.replace(/(&)?([a-z])([a-z]{2,})(;)?/ig,function ( all, prefix, letter, word, suffix ) {
        if (prefix && suffix) {
            return all;
        }

        return letter.toUpperCase() + word.toLowerCase();
    });
}
$("#breadcrumb1 a").text(function(i,text){
    return autoCase(text);
});

Answer 3

Try using css property text-transform:capitalize; for the breadcrumb.

Mostlikely in you case it should be,

.breadcrumb1 a {
   text-transform: capitalize;
}
