这是相机代码
<pre class="prettyprint">
var myData ="";
function onPhotoDataSuccess(imageData)
{
// alert('onPhotoDataSuccess');
var smallImage = document.getElementById('smallImage');
// Unhide image elements
smallImage.style.display = 'block';
// Show the captured photo
// The inline CSS rules are used to resize the image
smallImage.src = "data:image/jpeg;base64," + imageData;
myData = imageData;
}
function onPhotoURISuccess(imageURI)
{
// Get image handle
//
var largeImage = document.getElementById('largeImage');
// Unhide image elements
//
largeImage.style.display = 'block';
// Show the captured photo
// The inline CSS rules are used to resize the image
largeImage.src = imageURI;
}
function capturePhoto()
{
// Take picture using device camera and retrieve image as base64-encoded string
//alert('capturePhoto');
navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 50,destinationType: destinationType.FILE_URI, correctOrientation: true });
}
function capturePhotoEdit()
{
navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 20, allowEdit: true,destinationType: destinationType.FILE_URI });
}
function getPhoto(source)
{
// Retrieve image file location from specified source
navigator.camera.getPicture(onPhotoURISuccess, onFail, { quality: 50,destinationType: destinationType.FILE_URI,sourceType: source });
}
function onFail(message)
{
alert('Failed because: ' + message);
}
我试过了这个foureground插件，但客户并不欣赏它，也取消选中不要保留actitivies。 谢谢。
