JQuery Focus/Blur 和非 Jquery Focus/blur 在 IE 11 (Internet explorer 11) 上不起作用
JQuery Focus/Blur and non Jquery Focus/blur doesn't work on IE 11 (Internet explorer 11)
我想检测我的浏览器 window 是否有焦点(选中)。我使用以下代码来执行此操作:
$(window).focus(function() {
window.focusFlag = true;
}).blur(function() {
window.focusFlag = false;
});

Using JQuery to bind "focus" and "blur" functions for "window", doesn't work in IE
它适用于 mozilla firefox 43.0.4,但不适用于 IE 11。
我也试过focus/blur方法,不涉及JQuery。
function onBlur() {
document.body.className = 'blurred';
};
function onFocus(){
document.body.className = 'focused';
};
if (/*@cc_on!@*/false) { // check for Internet Explorer
document.onfocusin = onFocus;
document.onfocusout = onBlur;
} else {
window.onfocus = onFocus;
window.onblur = onBlur;
}

我能对 IE 11 做些什么?
标准为 focus
定义:
This event type is similar to focusin, but is dispatched after focus is shifted, and does not bubble.
https://www.w3.org/TR/uievents/#events-focusevent
因此,focusin
将适用于 jQuery 中的 parents。
<input type="text" />
$(window).focusin(function() {
alert("Focussed");
}).focusout(function() {
alert("Blur");
});
