如何从我的网站禁用(查看源代码)和(Ctrl + C)

Question

有没有机会从我的网站禁用这两件事？(查看源代码)和(Ctrl + C)

Answer 1

这是不可能的.您可以尝试以某种方式混淆代码,但您需要向客户端发送内容,不是吗？您可以使用AJAX调用来加载您的html.这样,浏览器显示的源几乎是空的.但是,您无法阻止有经验的用户查看您发送给客户端的所有内容.事实上,他/她可以使用很多工具来重建页面,任何你将努力应用的技术,只会让他/她延迟几分钟.

关于Ctrl-C你可以添加javascript来阻止它,但它没用,因为用户总是可以禁用javascript.实际上很多用户会发现拦截右键非常烦人.

如果您正在构建Intranet应用程序,或者您可以为用户提供集成浏览器以查看应用程序,则所有这些都有意义.使用公共HTML,我相信它甚至不值得尝试.一种解决方案是使用闪存或其他插件构建应用程序.这样您就可以加密发送给客户端的所有内容.

可以禁用 CTRL+U 和 CTRL+C。这可能有效：

shortcut = {
all_shortcuts: {},
  add: function (e, t, n) {
    var r = {
      type: "keydown",
      propagate: !1,
      disable_in_input: !1,
      target: document,
      keycode: !1
    };
    if (n) for (var i in r) "undefined" == typeof n[i] && (n[i] = r[i]);
    else n = r;
    r = n.target, "string" == typeof n.target && (r = document.getElementById(n.target)), e = e.toLowerCase(), i = function (r) {
      r = r || window.event;
      if (n.disable_in_input) {
        var i;
        r.target ? i = r.target : r.srcElement && (i = r.srcElement), 3 == i.nodeType && (i = i.parentNode);
        if ("INPUT" == i.tagName || "TEXTAREA" == i.tagName) return
      }
      r.keyCode ? code = r.keyCode : r.which && (code = r.which), i = String.fromCharCode(code).toLowerCase(), 188 == code && (i = ","), 190 == code && (i = ".");
      var s = e.split("+"),
        o = 0,
        u = {
          "`": "~",
          1: "!",
          2: "@",
          3: "#",

      for (var b = 0; k = s[b], b < s.length; b++) "ctrl" == k || "control" == k ? (o++, h = !0) : "shift" == k ? (o++, l = !0) : "alt" == k ? (o++, d = !0) : "meta" == k ?

      if (o == s.length && p == h && c == l && v == d && y == m && (t(r), !n.propagate)) return r.cancelBubble = !0, r.returnValue = !1, r.stopPropagation && (r.stopPropagation(), r.preventDefault()), !1
    }, this.all_shortcuts[e] = {
      callback: i,
      target: r,
      event: n.type
    }, r.addEventListener ? r.addEventListener(n.type, i, !1) : r.attachEvent ? r.attachEvent("on" + n.type, i) : r["on" + n.type] = i

  }
},
    shortcut.add("Ctrl+U",function(){
 // Script to be executed when user press CTRL+U;This also disable and cancel the CTRL+U method
}),
    shortcut.add("Ctrl+C",function(){
// Script to be executed when user press CTRL+C;This also disable and cancel the CTRL+C method
}),

对于演示，您可以访问我的小提琴：http : //jsfiddle.net/dVSRM/

所以结论是可以禁用 CTRL+U 和 CTRL+C。但是高级抄袭者可以知道这一点，从不使用快捷方式查看源代码。如果有人提出有关禁用查看源快捷方式的问题，此提示可以供您参考。但是 CTRL+C 包含在此脚本中。

这是我的脚本。谢谢你。回头见！
