如何替换数组中的字符串
我正在编写一段代码,该代码使用正则表达式来查找/替换聊天中的表情符号。但是,我想使用相同的值数组并将它们输出作为参考。
正则表达式对于我的搜索效果很好,但是当我在输出它以获取帮助之前尝试对正则表达式搜索字符串进行替换时,我仍然会得到斜杠。

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;
}
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.

您的问题是
str.replace
不会更改原始变量,而是返回一个新变量。试试这个:Your problem is that
str.replace
doesn't change the original variable but instead returns a new one. Try this out:
