Question

I’m having trouble replacing things like “joe.” in a regular expression. Here’s the code

var objects = new Array("joe","sam");  
code = "joe.id was here so was sam.id";  
for(i = 0; i < objects.length; i++) {  
    re = new RegExp(objects[i]+"\.", "g");  
    code = code.replace(re, "stan ");  
}

I’ve tried \., \\., \\\., but none of those seem to work.

Answer 1

Your code works perfectly with "\\."

var objects = new Array("joe","sam");  
code = "joe.id was here so was sam.id";  
for(i = 0; i < objects.length; i++) {  
    re = new RegExp(objects[i]+"\\.", "g");  
    code = code.replace(re, "stan ");  
}

"\\." creates the string \., which fits the bill.
