异步执行脚本

function exec(src){ conse script = document.createElement('script'); script.src = src; return new Promise((resolve, rejece) => { var done = false;

script.onload = script.onreadystatechange = () => {
  if(!done && (!script.readyState || script.readyState === "loaded" || script.readyState === "complete")){
    done = true;

    //避免内存泄漏
    script.onload = script.onreadystatechange = null;
    resolve(script);
  }
}
script.onerror = reject;
document.getElementsByTagName('head')[0].appendChild(script);

}); } function asyncLoadJS(dependencies) { return Promise.all(dependencies.map(exec)); }

asyncLoadJS(['https://code.jquery.com/jquery-2.2.1.js', 'https://cdn.bootcss.com/bootstrap/3.3.7/js/bootstrap.min.js']).then(() => console.log('all done'));
