script的onerror事件支持情况调查

时间：2011-02-12 来源：司徒正美

var el = document.createElement("script"); document.body.insertBefore(el,null); var name = "onerror" alert(name in el); el.setAttribute(name,""); alert(typeof el[name] === "function"); el.onerror = function(){ alert("支持onerror事件") } el.src = "test_"+1*new Date; setTimeout(function(){ var parent = el.parentNode if(parent && parent.nodeType === 1){ if (el.clearAttributes) { el.clearAttributes(); } else { el.onerror = null; } parent.removeChild(el) el = name = null; } },2000)

运行代码

看到没有IE678与opera就是一对活宝，真想砍死opera那帮人！

现在只能用这代码进行区分了：

//by 司徒正美
var supportScriptError = (!window.opera) && -[1,];
