禁止浏览器打开 F12 调试

1. 禁止页面选择

document.onselectstart = function(){
	return false;
};

2. 禁止鼠标右键

document.onselectstart = function(){
	return false;
};

3. 禁用开发者工具F12

document.onkeydown = function(event) {
	let e = event || window.event || arguments.callee.caller.arguments[0];
	if (e && e.keyCode === 123) {
		e.keyCode = 0;
		e.returnValue = false;
		return false;
	}
};

4. 禁止shift+ctrl+i调起开发者工具

document.onkeydown = document.onkeyup = document.onkeypress = function(event) {
	let e = event || window.event || arguments.callee.caller.arguments[0];
	if (e && e.shiftKey && e.ctrlKey && e.keyCode === 73) {
		e.preventDefault();
		return false;
	}
};

5. 浏览器窗口变化，无限debugger

(() => {
	function block() {
		if (window.outerHeight - window.innerHeight > 200 || window.outerWidth - window.innerWidth > 200) {
			document.body.innerHTML = "检测到非法调试,请关闭后刷新重试!";
		}
		setInterval(() => {
			(function () {
				return false;
			}
			['constructor']('debugger')
			['call']());
		}, 50);
	}
	try {
		block();
	} catch (err) { }
})();
