由于没有足够的细节，很难给您一个明确的答案-但是，如果您正确地调用了两个外部资源(如果需要，您还需要jQuery'正在使用此方法)，那么您应该收到所请求的警报.当您将资源内联(不包括jQuery)时，它的一个小提琴可以正常工作. https://jsfiddle.net/j3gbwvvg/.您不需要jQuery的原因是因为我们将数据直接放入变量中并调用了它，而不是使用利用了.getJSON()jQuery函数的库函数.

Hard to give you a definitive answer as there's not enough detail - but if you're calling the two external resources correctly (you'll also need jQuery if you're using this method), then you should get an alert as requested. Here's a fiddle of it working correctly when you bring the resources inline (which excludes the need for jQuery) https://jsfiddle.net/j3gbwvvg/. The reason you don't need jQuery is because we're putting the data directly into a variable and calling that, not using the library's function which utilises the .getJSON() jQuery function.

window.classifier = new ColorClassifier();
window.classifier.learn(data);
var result_name = window.classifier.classify("#aaf000");
alert(result_name);
