function AddLink()
{//Identify selected text
var sText = document.selection.createRange();
if (!sText==""){
//Create link
//Replace text with URL
if (sText.parentElement().tagName == "A"){
alert("Please select some blue text!");
<P unselectable="on">Select any portion of the following blue text, such as "My favorite Web site". Click the button to turn the selected text into a link. The text will be changed to the URL that you specify.</P>
<P style="color=#3366CC">My favorite Web site is worth clicking on. Don't forget to check out my favorite music group!</P>
<BUTTON onclick="AddLink()" unselectable="on">Click to add link</BUTTON>
