  • 禁用F12和鼠标右键,防止查看控制台代码

    虽然是个治标不治本的办法,还是挺有用的(对Opera无效,Opera开始控制台是Ctrl+Shift+C)

    在禁用同时,自身的代码健壮性也需要加强

    // 屏蔽F12
    document.onkeydown = function () {
        //f12键
        if (window.event && window.event.keyCode == 123) {
            event.keyCode = 0;
            event.returnValue = false;
        }
        // enter键
        // if (window.event && window.event.keyCode == 13) {
        //     window.event.keyCode = 505;
        // }
        // backspace键
        // if (window.event && window.event.keyCode == 8) {
        //     alert(str + "
    请使用Del键进行字符的删除操作!");
        //     window.event.returnValue = false;
        // }
    };
    
    // 屏蔽右键菜单 
    document.oncontextmenu = function (event) {
        if (window.event) {
            event = window.event;
        }
        try {
            var the = event.srcElement;
            if (!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")) {
                return false;
            }
            return true;
        } catch (e) {
            return false;
        }
    };
    
    // 屏蔽粘贴
    document.onpaste = function (event) {
        if (window.event) {
            event = window.event;
        }
        try {
            var the = event.srcElement;
            if (!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")) {
                return false;
            }
            return true;
        } catch (e) {
            return false;
        }
    };
    
    // 屏蔽复制
    document.oncopy = function (event) {
        if (window.event) {
            event = window.event;
        }
        try {
            var the = event.srcElement;
            if (!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")) {
                return false;
            }
            return true;
        } catch (e) {
            return false;
        }
    };
    
    // 屏蔽剪切
    document.oncut = function (event) {
        if (window.event) {
            event = window.event;
        }
        try {
            var the = event.srcElement;
            if (!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")) {
                return false;
            }
            return true;
        } catch (e) {
            return false;
        }
    };
