使用移动浏览器模拟器从相册中获取照片在 MobileFirst 中不起作用

Question

我正在尝试运行来自 phonegap 的这段代码，以便我可以将它集成到我的混合 android 应用程序中，该应用程序是使用 IBM MobileFirst 构建的。

拍摄照片按钮工作正常（来源：相机）

虽然其他按钮根本不起作用..我希望能够从我的画廊或相册中获取照片...

问题中的HTML不是基于MobileFirst Platform Foundation生成的Hybrid app；它缺少所有必需的参考资料。我并不惊讶这段代码根本不适合你。运行。

在 MFP Studio 中创建一个 MobileFirst 应用程序。这个应用程序将内置 Cordova。接下来您需要做的就是从 Cordova 添加与相机 API 相关的所需代码片段：

func wlCommonInit() {
    pictureSource=navigator.camera.PictureSourceType;
    destinationType=navigator.camera.DestinationType;
}

function onPhotoDataSuccess(imageData) {
   ...
   ...

HTML 应放在应用程序的 index.html 中。
还要在实际设备中进行测试。根据您在评论中所写的 - 它会在那里工作。
