Javascript search issue

Question

I have a piece of code that searches through a table looking for a certain phrase. Once it finds the phrase, it returns the innerHTML of the current cell to a div near the top o

As you are just wanting to check for presence of a specific string, I think your solution will probably be more robust if you use indexOf rather than RegExps.

Using RegExps, if you are looking for special characters eg [ or ] or ( or ) then you will need to escape them, this is just another layer of complexity which I don't think you need to introduce.

So try replacing regex usages such as...

if (currentRow.innerHTML.match(map_regex))

with this...

if (currentRow.innerHTML.indexOf(mapString)!=-1)
