我正在尝试检测 JavaScript 中的 HTML5 拖放支持.Modernizr 似乎无法处理这个测试用例.

I'm trying to detect the HTML5 Drag And Drop support in JavaScript. Modernizr seems to not handle this test case.

推荐答案

你可以这样做:

if('draggable' in document.createElement('span')) { alert("Drag support detected"); }

您可以在此处查看使用上述检查的快速演示测试.

另外，这里有一个很好的功能检测(不是浏览器检测，耶！)列表，这里维护得很好如果您也在寻找其他 HTML5 功能.

Also, there's a nice feature detection (not browser detection, yay!) list that's fairly well maintained here in case you're looking for other HTML5 features as well.
