How to replace strings from an array

Pergunta
I'm working on a piece of code that uses regex expressions to do a find/replace for emoticons in a chat. However, I want to use the same array of values and output them as a reference.
The regex works fine for my searches, but when I tried to do a replace on the regex search string before I output it for my help, I still end up with a slash.
:\)
:\(
var emotes = [];
emotes[0] = new Array(':\\\)', 'happy.png');
emotes[1] = new Array(':\\\(', 'sad.png');
function listEmotes(){
var emotestext = '';
for(var i = 0; i < emotes.length; i++){
//Tried this and it doesn't seem to work
//var emote = emotes[i][0];
//emote.replace('\\', '');
emotestext += '<ul>' + emote + ' <img src="emotes/' + emotes[i][1] + '"></ul>';
}
return emotestext;
}
Solução
Your problem is that str.replace
doesn't change the original variable but instead returns a new one. Try this out:
var emotes = [
[':\\\)', 'happy.png'],
[':\\\(', 'sad.png']
];
function listEmotes(){
var emotestext = '';
for(var i = 0; i < emotes.length; i++){
var emote = emotes[i][0].replace('\\', ''); // See what I did here?
emotestext += '<ul>' + emote + ' <img src="emotes/' + emotes[i][1] + '"></ul>';
}
return emotestext;
}
