javascript:(function(){script=document.createElement('script');script.src='https://cdn.bootcss.com/jquery/3.2.1/jquery.min.js';document.body.appendChild(script);console.log($.fn.jquery);})();

2. 使用console-importer

$i('jquery')   #添加jquery


<script type="text/javascript">
    _([1, 2]).forEach(function(value) {
        console.log(value);
    });
    _.forEach([1, 3] , function(value, key) {
