判斷是否篡改不容易，但妳可以禁止開啟控制臺，不準按f12，或者右鍵打開審查元素。
<script?type='text/javascript'>?
//這段js要放在頁面最下方?
var?h?=?window.innerHeight,w=window.innerWidth;?
//禁用右鍵?（防止右鍵查看源代碼）?
window.oncontextmenu=function(){return?false;}?
//在本網頁的任何鍵盤敲擊事件都是無效操作?（防止F12和shift+ctrl+i調起開發者工具）?
window.onkeydown?=?window.onkeyup?=?window.onkeypress?=?function?()?{?
window.event.returnValue?=?false;?
return?false;?
}?
//如果用戶在工具欄調起開發者工具，那麽判斷瀏覽器的可視高度和可視寬度是否有改變，如有改變則關閉本頁面?
window.onresize?=?function?()?{?
if?(h?!=?window.innerHeight||w!=window.innerWidth){?
window.close();?
window.location?=?"about:blank";?
}?
}?
/*好吧，妳的開發者工具是單獨的窗口顯示，不會改變原來網頁的高度和寬度，?
但是妳只要修改頁面元素我就重新加載壹次數據,讓妳無法修改頁面元素（不支持IE9以下瀏覽器）*/?
