RegExp.replace Not Working

Jan 28th, 2006

I'm using the following function to modify tags used for mouseover text:

 Help with Code Tags 
 JavaScript / DHTML / AJAX Syntax (Toggle Plain Text) 
function delHoverX()
{
  re = /(\bdsc00001\b)/i;
 
  imgTags = document.getElementsByTagName("img");
  for (i=0; i<imgTags.length; i++)
  {
    if (re.test(imgTags[i].title))
    {
      origTitle = imgTags[i].title;
      origAlt = imgTags[i].alt;
      imgTags[i].title.replace(re, "$1");
      imgTags[i].alt.replace(re, "$1");
      if (origTitle == imgTags[i].title && origAlt == imgTags[i].alt)
        {
        imgTags[i].title = "same";
        imgTags[i].alt = "same";
        }
    }
    else
    {
      imgTags[i].title = "";
      imgTags[i].alt = "";
    }
  }
}
function delHoverX()
{
  re = /(\bdsc00001\b)/i;

  imgTags = document.getElementsByTagName("img");
  for (i=0; i<imgTags.length; i++)
  {
    if (re.test(imgTags[i].title))
    {
      origTitle = imgTags[i].title;
      origAlt = imgTags[i].alt;
      imgTags[i].title.replace(re, "$1");
      imgTags[i].alt.replace(re, "$1");
      if (origTitle == imgTags[i].title && origAlt == imgTags[i].alt)
        {
        imgTags[i].title = "same";
        imgTags[i].alt = "same";
        }
    }
    else
    {
      imgTags[i].title = "";
      imgTags[i].alt = "";
    }
  }
}

It is being used on the following web page: http://huntsvillecarscene.smugmug.com/gallery/1144571

For some reason, the regexp.replace is not working. There is a test clause in there to help me diagnose some of what's going on.

I'm not a Javascript programmer. I only have a limited background in C. I've been working on this for 2 days and am frustrated out of my mind.

Any assistance appreciated.

Regular Expressions have always been very difficult for me, for some reason. I'd be happy to try to help when I have a bit more time later this week.

Can you post a very simple "test harness" version of your HTML here?

it should be \i not /i for case insensitive in your re (first line of code) so you are possibly never getting a match. its is easy to miss as some others are / (for example /g for whole string)
