我正在为包含2种分隔符的令牌解析字符串（类似于胡子模板）。
我需要一个与{{bob}}中的this is {{bob}} a double token匹配的纯注册解决方案。但在this is {{{bob}}} a triple token
我将双重匹配
\{\{[^\{]([\s\S]+?)[^\}]\}\}
但是，它与三{{bob}}内的{{{bob}}}匹配。
如果没有消极的看法，我很难找到一个纯粹的正则表达式解决方案。有什么指针吗？

您可以搜索括号外的任何空白字符，如下所示：
$(document).on('auxclick', 'a', function(e) {
if (e.which === 2) { //middle Click
e.preventDefault();
e.stopPropagation();
e.stopImmediatePropagation();
return false;
}
return true;

<强>正则表达式：
^(\}?)\{\{[^\{]([\s\S]+?)[^\}]\}\}
自动生成说明：
^ asserts position at start of the string
1st Capturing Group (\}?)
\}? matches the character } literally (case sensitive)
? Quantifier — Matches between zero and one times, as many times as possible, giving back as needed (greedy)
\{ matches the character { literally (case sensitive)
\{ matches the character { literally (case sensitive)
Match a single character not present in the list below [^\{]
\{ matches the character { literally (case sensitive)
2nd Capturing Group ([\s\S]+?)
Match a single character present in the list below [\s\S]+?
+? Quantifier — Matches between one and unlimited times, as few times as possible, expanding as needed (lazy)
\s matches any whitespace character (equal to [\r\n\t\f\v ])
\S matches any non-whitespace character (equal to [^\r\n\t\f ])
Match a single character not present in the list below [^\}]
\} matches the character } literally (case sensitive)
\} matches the character } literally (case sensitive)
\} matches the character } literally (case sensitive)
Global pattern flags
g modifier: global. All matches (don't return after first match)

您可以使用以下内容来提取匹配项：
var s = "this is {{{ bad bob triple}}} a triple token {{bob double}} {{bob}} a double token {{{bad token}} {{bad token}}}";
var rx = /(?:^|[^{]){{([^{}]*)}}(?!})/g;
var m, res=[];
while(m=rx.exec(s)) {
res.push(m[1]);
}
console.log(res);
请参阅regex demo here。
(?:^|[^{]) - 字符串的开头或{ {{ - 加倍{ ([^{}]*) - 第1组：任何字符{和}零次或多次}} - 加倍} (?!}) - 没有立即跟上}。
