移動網大、移動網校切屏屏蔽和複製，怎麼辦？有方法解除切屏和複製限制嗎？

最近有粉絲問我這個考試網站有辦法解除屏蔽嗎？https://wangda.chinamobile.com/

//解除切屏限制
window.onmouseleave = window.onblur = window.onmouseout = document.onmouseleave = document.onblur = document.onmouseout = document.body.onmouseleave = document.body.onblur = document.body.onmouseout = onmouseleave = onblur = onmouseout = null;

//解除選中文本限制（這裏html看具體考試頁面綁定的限制事件dom而定）
window.onselectstart = document.onselectstart = document.body.onselectstart = onselectstart = document.querySelector("html").onselectstart = null;

//解除複製粘貼限制
window.oncopy = window.onpaste = document.oncopy = document.onpaste = document.body.oncopy = document.body.onpaste = oncopy = onpaste = null;

//解除右鍵菜單限制（這裏html看具體考試頁面綁定的限制事件dom而定）
window.oncontextmenu = document.oncontextmenu = document.body.oncontextmenu = oncontextmenu = document.querySelector("html").oncontextmenu = null;

//解除快捷鍵操做屏蔽
window.onkeyup = window.onkeydown = window.onKeyPress = document.onkeyup = document.onkeydown = document.onKeyPress = document.body.onkeyup = document.body.onkeydown = document.body.onKeyPress = onkeyup = onkeydown = onKeyPress = null;
