JS获取一个字符串中被指定的两个字符串包括起来的所有字符串数组

let getStrinsBetweenTwoStrings = (targetString, beginString, endString) => {
    let aa = targetString.split(beginString), re = [];
    for (let i = 1, len = aa.length; i < len; i++) {
        let a = aa[i],s = a.split(endString)[0];
        s && re.push(s);
    }
    return re;
};



//测试----------------------------------------
console.log(getStrinsBetweenTwoStrings("一[句话]里面[有]很[多个]方[括号]", "[", "]"));
//[ '句话', '有', '多个', '括号' ]


console.log(getStrinsBetweenTwoStrings("我◆◆和我❤❤❤的祖国，◆◆一刻❤❤❤也◆◆不能❤❤❤◆◆分割❤❤❤，无论我走到哪里，都流出◆◆一首赞歌❤❤❤", "◆", "❤❤"));
//[ '和我', '一刻', '不能', '分割', '一首赞歌' ]
