问题 I was wondering if there is a MooTools equivalent to jQuery's .getScript() ? I'm pretty certain that this exists somewhere in MooTools but I haven't been able to find it yet. 回答1: I'm not that familiar with MooTools, but it looks like you can use Asset.javascript. var myScript = Asset.javascript('/scripts/myScript.js', { id: 'myScript', onLoad: function(){ alert('myScript.js is loaded!'); } }); 来源： https://stackoverflow.com/questions/6065725/getscript-equivalent-in-mootools
