我建立使用PhoneGap的Android中移動應用程序,我試圖一個div的背景設置爲使用相機拍攝的照片。設置DIV背景合影留念用相機
我有相機工作正常(下面的代碼),但拍照後我要馬上定身div的背景圖片的照片,而不是僅僅向用戶顯示他們的照片。
var pictureSource; // picture source
var destinationType; // sets the format of returned value
// Wait for PhoneGap to connect with the device
//
document.addEventListener("deviceready",onDeviceReady,false);
// PhoneGap is ready to be used!
//
function onDeviceReady() {
pictureSource=navigator.camera.PictureSourceType;
destinationType=navigator.camera.DestinationType;
}
// Called when a photo is successfully retrieved
//
function onPhotoDataSuccess(imageData) {
// Uncomment to view the base64 encoded image data
// console.log(imageData);
// Get image handle
//
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;
//set the background here?
$('#wrapper').css("background-image", "url(imageData.jpg)");
}
// Called when a photo is successfully retrieved
//
function onPhotoURISuccess(imageURI) {
// Uncomment to view the image file URI
// console.log(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;
}
// A button will call this function
//
function capturePhoto() {
// Take picture using device camera and retrieve image as base64-encoded string
navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 50 });
}
// A button will call this function
//
function capturePhotoEdit() {
// Take picture using device camera, allow edit, and retrieve image as base64-encoded string
navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 20, allowEdit: true });
}
// A button will call this function
//
function getPhoto(source) {
// Retrieve image file location from specified source
navigator.camera.getPicture(onPhotoURISuccess, onFail, { quality: 50,
destinationType: destinationType.FILE_URI,
sourceType: source });
}
// Called if something bad happens.
//
function onFail(message) {
alert('Failed because: ' + message);
}
將背景設置在前面的代碼中,我使用了以下內容:
$('#wrapper').css("background-image", "url(imageData.jpg)")
任何幫助將是巨大的。
究竟是不是爲你工作這個工作給我嗎?是什麼讓你做$(「#包裝」)。CSS(「背景圖片」,largeimage)?或者是對用戶沒有得到相機取消,接受屏幕的問題>? – alonisser
那麼,什麼是你的問題有?請告訴我問題呢? – Christopher
我在底部提示這行代碼是行不通的,它只是給我想要的東西的想法。 – jcrowson
