PhoneGap CameraAPI返回三次空

问题描述

| 当从手机库中选择任何照片时，我编写的以下代码始终返回null。

<script type=\"text/javascript\">
        var imgData = null;
        var pictureSource = null;
        var destinationType = null;

    function onLoad() {
            document.addEventListener(\"deviceready\",onDeviceReady,false);
        }

        function onDeviceReady() {
            pictureSource = navigator.camera.PictureSourceType;
            destinationType = navigator.camera.DestinationType;
        }

        function selectPhotoFromLibrary(e) {
            if (e) e.preventDefault();

            navigator.camera.getPicture(onSuccess,onFail,{
                    sourceType: pictureSource.PHOTOLIBRARY,destinationType: destinationType.DATA_URL
                }
            );
        }

        function selectPhotoFromAlbums(e) {
            if (e) e.preventDefault();

            navigator.camera.getPicture(onSuccess,{
                    quality: 50,sourceType: pictureSource.SAVEDPHOTOALBUM,destinationType: destinationType.DATA_URL
                }
            );
        }

        function onSuccess(data) {
            alert(data);
            imgData = data;
        }

        function onFail(msg) {
            navigator.notification.alert(msg,null,\"Error\",\"OK\");
        }
    </script>

的HTML

<div id=\"buttons\">
                <input value=\"Select Photo From Library\" style=\"margin: 5px; width: 95%;\" onclick=\"selectPhotoFromLibrary(event)\" type=\"button\">
                <br>
                <input value=\"Select Photo From Albums\" style=\"margin: 5px; width: 95%;\" onclick=\"selectPhotoFromAlbums(event)\" type=\"button\">
            </div>
