答
JavaScript中没有捕获所有组匹配项"(类似于PHP的 preg_match_all )，但是您可以使用.替换:
There is no "capture all group matches" (analogous to PHP's preg_match_all) in JavaScript, but you can cheat by using .replace:
var matches = [];
html.replace(/<p>(.*?)<\/p>/g, function () {
//arguments[0] is the entire match
matches.push(arguments[1]);
});
