<a href="#" class="btn" onclick="scanCode();">Scan Code</a>
<script type="text/javascript">
function scanCode() {
    cordova.plugins.barcodeScanner.scan(
      function (result) {
          alert("We got a barcode\n" +
                "Result: " + result.text + "\n" +
                "Format: " + result.format + "\n" +
                "Cancelled: " + result.cancelled);
      }, 
      function (error) {
          alert("Scanning failed: " + error);
      }
   );
}
</script>

<a href="#" class="btn enc" onclick="encodeText();">Encode Text</a>
<script type="text/javascript">
function encodeText() {
    cordova.plugins.barcodeScanner.encode(
      "TEXT_TYPE", 
      "http://www.baidu.com", 
      function(success) {
        alert("encode success: " + success);
      }, function(fail) {
        alert("encoding failed: " + fail);
      }
    );
}
</script>

<a href="#" class="btn enc" onclick="encodeEmail();">Encode Email</a>
<script type="text/javascript">
function encodeEmail() {
    cordova.plugins.barcodeScanner.encode(
      "EMAIL_TYPE", 
      "rensanning@gmail.com", 
      function(success) {
        alert("encode success: " + success);
      }, function(fail) {
        alert("encoding failed: " + fail);
      }
    );
}
</script>

<a href="#" class="btn enc" onclick="encodePhone();">Encode Phone</a>
<script type="text/javascript">
function encodePhone() {
    cordova.plugins.barcodeScanner.encode(
      "PHONE_TYPE", 
      "135-1234-5678", 
      function(success) {
        alert("encode success: " + success);
      }, function(fail) {
        alert("encoding failed: " + fail);
      }
    );
}
</script>

<a href="#" class="btn enc" onclick="encodeSMS();">Encode SMS</a>
<script type="text/javascript">
function encodeSMS() {
    cordova.plugins.barcodeScanner.encode(
      "SMS_TYPE", 
      "An important message for someone.", 
      function(success) {
        alert("encode success: " + success);
      }, function(fail) {
        alert("encoding failed: " + fail);
      }
    );
}
</script>

注意：

a) 没有实现CONTACT_TYPE 和 LOCATION_TYPE的encode。
b) 如果encode出错：

java.lang.NullPointerException
   at com.google.zxing.client.android.encode.EncodeActivity.onCreateOptionsMenu(EncodeActivity.java:89)

下载最新的encode.xml文件，覆盖 platforms\android\res\menu\encode.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:id="@+id/menu_share"
        android:title="@string/menu_share"
        android:icon="@android:drawable/ic_menu_share"
        android:orderInCategory="1"
        android:showAsAction="withText|ifRoom"/>
  <item android:id="@+id/menu_encode"
        android:title="@string/menu_encode_vcard"
        android:icon="@android:drawable/ic_menu_sort_alphabetically"
        android:orderInCategory="2"
        android:showAsAction="withText|ifRoom"/>
</menu>
