我正在使用 Phonegap 3.0.0 相机插件 ( https://build.phonegap.com/plugins/242 )。我想让用户上传一张照片。 sourcetype 的当前选项是:
Camera.PictureSourceType.CAMERA
Camera.PictureSourceType.SAVEDPHOTOALBUM
Camera.PictureSourceType.PHOTOLIBRARY
是否有任何 sourcetype 可以同时向用户显示所有这三个选项？我希望用户能够选择画廊或相机。我认为这是您单击 < input type="file"/> 时移动浏览器中的典型行为。 .
最佳答案
试试这个:
技巧:
<input type="file" capture="camera" accept="image/*" id="takePictureField">
