<script type="text/javascript" >

   $(document).ready(function(){
       $("p").on("mouseup" , function(){
          selectedtext = selectedText();
          var replceText = "<span style='background:#cccccc' >"+selectedtext+"</span>";
          var gethtmlText = $(this).text();
          var replcedtext = gethtmlText.replace(selectedtext ,  replceText);

The following code works when you select a text or word, the color will change:

<style>
::selection {
    color:blue;
    background:yellow;
    font-size:14px;
}

::-moz-selection {
    color:blue;
    background:yellow;
    font-size:14px;
}
</style>

Check DEMO here http://jsfiddle.net/yeyene/GYuBv/7/

Select text, and click button to change selected text color.

function selectHTML() {
    try {
        if (window.ActiveXObject) {
            var c = document.selection.createRange();
            return c.htmlText;
        }

        var nNd = document.createElement("span");
        var w = getSelection().getRangeAt(0);
        w.surroundContents(nNd);
        return nNd.innerHTML;
    } catch (e) {
        if (window.ActiveXObject) {
            return document.selection.createRange();
        } else {
            return getSelection();
        }
    }
}

$(function() {
    $('#changeColor').click( function() {
        var mytext = selectHTML();
        // you can modify any css style here...
        $('span').css({"color":"red"});
    });
});

Answer 5

I've created a pretty short fiddle that demonstrates the use of jQuery to change the color of a piece of text.

HTML:

<p id="paragraph">Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque laudantium?</p>
<button id="colorChanger">This Button changes the text color of the paragraph.</button>

CSS:

#paragraph {
    color: green;
}

JavaScript:

$('#colorChanger').click(function() {
    $('#paragraph').css('color','black');
});

The code above shows that with any text you can change the color using jQuery's css method. Additionally, I used #paragraph to access the paragraph; however, you can use nth-child through jQuery, you can cycle through the children of a container using a loop and checking for the right one then using the css method from jQuery. These are just a few of the ways to change the color of a piece of text.
