废话不多说了，直接给大家贴代码了，具体代码如下所示：
var msg="dsada[emoji:37]dsadas[emoji:3900]法拉?芬河";
function fetch(msg) {
var match, result = msg,
reg = /\[emoji:\d+\]/g,
emojiIndex,
totalEmojiNum = 45;
while (match = reg.exec(msg)) {
console.log(match[0]);//[emoji:37],[emoji:3900]
emojiIndex = match[0].slice(7, -1);
console.log(emojiIndex);//37,3900
if (emojiIndex > totalEmojiNum) {
result = result.replace(match[0], '[X]');
} else {
result = result.replace(match[0], '<img src="images/eomji_' + emojiIndex + '.gif" />');
};
};
return result;//"dsada<img src="images/eomji_37.gif" />dsadas[X]法拉?芬河"
}
fetch(msg);
