Example

The following example shows how to use the CreateLink constant as the sCommand of the execCommand method to allow the user to create a hyperlink from selected text. The scriptMicrosoft JScript then retrieves the specified URL and uses it to replace the selected text.

<script type="text/javascript">
function AddLink()
{
    //identify selected text
    var sText = document.selection.createRange();
    if (sText.text != "")
    {
      //create link
      document.execCommand("CreateLink");
      //change the color to indicate success
      if (sText.parentElement().tagName == "A")
      {
        sText.execCommand("ForeColor",false,"#FF0033");
      }
    }
    else
    {
        alert("Please select some text!");
    }   
}
</script>

favorite Web site&quot;. Click the button to turn the selected text into a link. </p>
<p style="color= #3366CC">My favorite Web site is worth clicking on. Don't forget
