First word selector

Question

How can I select the first word in a div?

I need to be able to insert a line break after the first word, or wrap it in a span tag. I need to do this for multiple divs on a page with the same class.

Actually, if you want to use it as a plugin, so that it would do it for all the items in the selector, not only the first one, use this one:

$.fn.wrapStart = function(numWords){
    return this.each(function(){
        $this = $(this);
        var node = $this.contents().filter(function(){
            return this.nodeType == 3
        }).first(),
        text = node.text(),
        first = text.split(" ", numWords).join(" ");
        if (!node.length) return;
        node[0].nodeValue = text.slice(first.length);
        node.before('<span>' + first + '</span>');
    });
};

$.fn.lastWord = function() {
  var text = this.text().trim().split(" ");
  var last = text.pop();
  this.html(text.join(" ") + (text.length > 0 ? " <span class='lastWord'>" + last + "</span>" : last));
};


$.fn.firstWord = function() {
  var text = this.text().trim().split(" ");
  var first = text.shift();
  this.html((text.length > 0 ? "<span class='firstWord'>"+ first + "</span> " : first) + text.join(" "));
};


$("#firstWord").firstWord();
$("#lastWord").lastWord();

Replacing HTML will result in event handlers being unbound and replacing the entire text for an element will result in HTML markup being lost. The best approach leaves any HTML untouched, manipulating only the first text node of the matching element. To get that text node, you can use .contents() and .filter():

function wrapFirstWord () { 
    // Select only the first text node
    var node = $("div").contents().filter(function () { 
            return this.nodeType == 3;
        }).first(),

    // Get the text... 
        text = node.text(),

    // ... and the first word
        first = text.slice(0, text.indexOf(" "));

    if (!node.length)
        return;

    // Remove the first word from the text
    node[0].nodeValue = text.slice(first.length);

    // Add it back in with HTML around it
    node.before('<span>' + first + '</span><br/>');
};

Using this method will ensure that manipulating the first word will have no unwanted side effects on the rest of the element's content.

You can easily tack this on as an extension to jQuery, with an optional value for the number of words you want to wrap:

$.fn.wrapStart = function (numWords) { 
    var node = this.contents().filter(function () { 
            return this.nodeType == 3 
        }).first(),
        text = node.text(),
        first = text.split(" ", numWords).join(" ");

    if (!node.length)
        return;

    node[0].nodeValue = text.slice(first.length);
    node.before('<span>' + first + '</span><br/>');
};

This should work:

$('div.message').each(function() {
   var html = $(this).html();
   var word = html.substr(0, html.indexOf(" "));
   var rest = html.substr(html.indexOf(" "));
   $(this).html(rest).prepend($("<span/>").html(word).addClass("em"));
});

basicly you can do like this

$('ELEMENT_SELECTOR').text().split(' ')[0]
