js禁止右键或F12查看源代码

document.oncontextmenu = function () { return false; };
        document.onkeydown = function () {
            if (window.event && window.event.keyCode == 123) {
                event.keyCode = 0;
                event.returnValue = false;
                return false;
            }
        };

//防止默认就是打开f12的

if(window.console&&window.console.log){
window.location.href = 'about:blank';
//console.log("打开了控制台")
}
