Question

I use some jquery to highlight search results. For some reason if i enter a basis dot, all of the text get selected. I use regex and replace to wrap the results in a tag to give the found matches a color.

the code that i use

 var pattern = new.RegExp('('+$.unique(text.split(" ")).join("|")+")","gi");

how can i prevent that the dot selects all text, so i want to leave the point out of the code(the dot has no power)

Answer 1

You may be able to get there by doing this:

var pattern = new.RegExp('('+$.unique(text.replace('.', '\\.').split(" ")).join("|")+")","gi");

The idea here is that you’re attempting to escape the period, which acts as a wild card in regex.
