JavaScript检查是否按下F12,并自动跳转到指定地址.

!function(e) {

function n(e) {
    function n() {
        return u
    }

    function o() {
        window.Firebug && window.Firebug.chrome && window.Firebug.chrome.isInitialized ? t("on") : (a = "off", console.log(d), console.clear(), t(a))
    }

    function t(e) {
        u !== e && (u = e, "function" == typeof c.onchange && c.onchange(e))

    function r() {
        l || (l = !0, window.removeEventListener("resize", o), clearInterval(f))
