我在使用SSLCertificate.Checker时未定义TypeError：window.plugins

Question

使用SSLCertificate checker插件时遇到问题。 它给出了window.plugins未定义的错误。 我从git添加了插件，并使用与git中的define相同的方式。 但我不知道我哪里出错了。 代码片段！

 var app = {
        // Application Constructor
        initialize: function() {
            document.addEventListener('deviceready', this.onDeviceReady.bind(this), false);
            document.getElementById("btcon",addEventListener("click",makeconnection));
            function makeconnection(){
        var server = "https://build.phonegap.com";
        var fingerprint = "2B 24 1B E0 D0 8C A6 41 68 C2 BB E3 60 0A DF 55 1A FC A8 45";

      window.plugins.sslCertificateChecker.check(
              successCallback,
              errorCallback,
              server,
              fingerprint);

       function successCallback(message) {
         alert(message);
         alert("Successful");
         // Message is always: CONNECTION_SECURE.
         // Now do something with the trusted server.
       }

       function errorCallback(message) {
         alert(message);
         if (message == "CONNECTION_NOT_SECURE") {
           // There is likely a man in the middle attack going on, be careful!
           alert("Connection is not secured!");
         } else if (message.indexOf("CONNECTION_FAILED") >- 1) {
           // There was no connection (yet). Internet may be down. Try again (a few times) after a little timeout.
           alert("Connection Failed");
         }
       }
        }
        },
