仅当我单击一个元素而不是html元素时，mousedown-event才起作用。为什么，我该怎么办？
var curFocus;
$(document.body).delegate('*','mousedown', function(){
if ((this != curFocus) && // don't bother if this was the previous active element
($(curFocus).is('.field')) // if it was a .field that was blurred
) {
$('.' + $(curFocus).attr("id")).removeClass("visible"); // take action based on the blurred element
}
curFocus = this; // log the newly focussed element for the next event
});
最佳答案
<html>标记有点笼统，它包含诸如<head>的不可见元素，请尝试使用<body>标记。
