Javascript replace not working as expected

Question

This is my code

var tmp = document.body.outerHTML.match(/<b>Location: <\/b>([^,]+),([^,]+),([^,])([^\s]+) <br>/i);
DataExtractor.AddHeader(14, 'id_country');
 var country
 if( tmp ){country = tmp[1]
 }
 else{alert('country is not set')} 
DataExtractor.AddResult(14, country);`

This returns the value of 'UK' or 'USA' or whatever is the country code is, but I need to replace this value to correspond with a country ID stored elsewhere so they can be compared. I therefore need to be able to tell this piece of code to replace the value UK with 75. I have tried the following, but it just didn't work.

var tmp = document.body.outerHTML.match(/<b>Location: <\/b>([^,]+),([^,]+),([^,])([^\s]+) <br>/i);
DataExtractor.AddHeader(14, 'id_country');
 var country
 if( tmp ){country = tmp[1]
 if (country){
 for (var i = 0; i < country.length; i++) {
 country[i] = country[i].replace("UK","75")
}
 else{alert('country is not set')}
DataExtractor.AddResult(14, country[i]);
}}

Does anyone see where it's gone wrong?

• apsillers: The code you have posted here is not syntactically valid -- where should the closing quote and parenthesis go in that final alert? Additionally, it would be helpful if you could indent your code blocks so it's easier for people to understand your problem and answer your question.

Answer 1

country contains a string - eg "UK" and you are then taking each character of it "U" or "K" and trying to replace "UK" with "75" which never matches.

if (country){
 country = country.replace("UK","75")
}

This should work
