JS禁用右鍵+禁用Ctrl+u+禁用F12

第一種方法：

var arr = [123, 17, 18]; document.oncontextmenu = new Function("event.returnValue=false;"),//禁用右鍵
document.onselectstart = new Function("event.returnValue=false;"),//禁用選中
window.onkeydown = function (e) { var code = e.keyCode; if (arr.indexOf(code) > -1) { console.log("中招了", code); e.preventDefault(); } }, window.oncontextmenu = function (e) { e.preventDefault(); }

第二種方法：

var arr = [123, 17, 18]; document.oncontextmenu = new Function("event.returnValue=false;"),//禁用右鍵
 window.onkeydown = function (e) { var keyCode = e.keyCode || e.which || e.charCode; var ctrlKey = e.ctrlKey || e.metaKey; console.log(keyCode + "--" + keyCode); if (ctrlKey && keyCode == 85) { console.log("ctrl+u"); e.preventDefault(); } if (arr.indexOf(keyCode) > -1) { console.log("其餘"); e.preventDefault(); } //e.preventDefault(); //return false;
}
