Javascript Cookies 通过正则表达式名称获取

Question

嗨，假设我在浏览器缓存中有这个 cookie，我如何通过正则表达式名称获取 cookie

name:  value:
text1  something
test   something
text2  something
4      bla

比如获取 cookies 正则表达式 ('test'+onlynumbers)

返回

text1  something
text2  something

Answer 1

像这样的东西应该可以工作(未经测试):

var getCookieByMatch = function(regex) {
  var cs=document.cookie.split(/;\s*/), ret=[], i;
  for (i=0; i<cs.length; i++) {
    if (cs[i].match(regex)) {
      ret.push(cs[i]);
    }
  }
  return ret;
};
getCookieByMatch(/^text\d+=/); // => ["text1=x;...", "text2=y..."]
