我目前正在使用 Phonegap/Cordova 和 jQuerymobile 构建 iOS 应用程序。这个想法是用相机拍照并存储捕获的图像以供将来使用。我想将路径/文件名存储到本地数据库中,并将图片文件移动到 iPhone 中的持久位置。
有人能给我举个例子吗?
好的,这是解决方案。
在 HTML 文件中
我有一个用于显示相机拍摄的照片的图像标签:
我有一个运行拍照功能的按钮:
拍摄照片
-
拍摄照片的函数是(拍摄照片时,'smallImage'id的scr会填充照片的路径)
function capturePhoto() {
// Take picture using device camera and retrieve image as base64-encoded string
navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 50 });
}
//Callback function when the picture has been successfully taken
function onPhotoDataSuccess(imageData) {
// Get image handle
var smallImage = document.getElementById('smallImage');
// Unhide image elements
smallImage.style.display = 'block';
smallImage.src = imageData;
}
//Callback function when the picture has not been successfully taken
function onFail(message) {
alert('Failed to load picture because: ' + message);
}
-
现在我想将图片移动到永久文件夹中,然后将链接保存到我的数据库中:
function movePic(file){
window.resolveLocalFileSystemURI(file, resolveOnSuccess, resOnError);
}
//Callback function when the file system uri has been resolved
function resolveOnSuccess(entry){
var d = new Date();
var n = d.getTime();
//new file name
var newFileName = n + ".jpg";
var myFolderApp = "EasyPacking";
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function(fileSys) {
//The folder is created if doesn't exist
fileSys.root.getDirectory( myFolderApp,
{create:true, exclusive: false},
function(directory) {
entry.moveTo(directory, newFileName, successMove, resOnError);
},
resOnError);
},
resOnError);
}
//Callback function when the file has been moved successfully - inserting the complete path
function successMove(entry) {
//I do my insert with "entry.fullPath" as for the path
}
function resOnError(error) {
alert(error.code);
}
我的文件已保存在数据库中以显示它,我将“file://”放在包含图像 src 的行前面
希望这有帮助。
