[thelist] Textarea formating

[dave gray]

actually, this should be:

function makeBold(){
  var fullText = document.forms[0].fred.value;
// the function on the next line probably doesn't exist...
// i forget how to do that 'get the user-selected text
// from the browser' thing...
  var selectedText = document.selectedText.createRange();
  var whatToMatch = new RegExp(selectedText);
// the important change was here... there would be no .leftContext
// or .rightContext the way i did it before DOH
  var resultArray = whatToMatch.exec(fullText);
  newText = whatToMatch.leftContext + "<b>" + whatToMatch.lastMatch +
  "</b>" + whatToMatch.rightContext;
  document.forms[0].fred.value=newText;
}

...

<textarea name=fred></textarea>
<a href="javascript:void(makeBold())">make selected text bold</a>

if anyone really cares :)
