html5怎么实现只调用手机摄像头

Answer 1

需要加载cordova.js
方法：

document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
pictureSource = navigator.camera.PictureSourceType;
destinationType = navigator.camera.DestinationType;
}
//相册
function fromCamera()
{
var source = pictureSource.PHOTOLIBRARY;
navigator.camera.getPicture(function (imageData) {
setimg(imageData);
}, function (message) {
if (source == pictureSource.CAMERA)
alert('加载照相机出错!' + message);
else
alert('加载相册出错!' + message);
}, {
quality: 50,
destinationType: destinationType.FILE_URI,
sourceType: source
});
}
//拍照
function EditImgPz()
{
navigator.camera.getPicture(function (imageData) {
setimg(imageData);
}, function (message) {
alert(message);
}, {
quality: 50,
destinationType: navigator.camera.DestinationType.FILE_URI,
sourceType: Camera.PictureSourceType.CAMERA,
allowEdit: true,
encodingType: Camera.EncodingType.JPEG,
popoverOptions: CameraPopoverOptions,
saveToPhotoAlbum: true
});
}
