应用升级

function upgrade(url) {	plus.nativeUI.showWaiting("升级中...");	var dtask = plus.downloader.createDownload(url, {		method: "GET"	}, function(d, status) {		if(status == 200) {			console.log("下载升级包成功: " + d.filename);			plus.runtime.install(d.filename, {}, function() {				plus.nativeUI.closeWaiting();				plus.nativeUI.alert("更新成功, 需要重新启动!", function() {					plus.runtime.restart();				});			}, function(e) {				plus.nativeUI.closeWaiting();				alert("更新失败: " + e.message);			});		} else {			plus.nativeUI.closeWaiting();			alert("下载升级包失败: " + status);		}	});//	dtask.addEventListener('statechanged', function(d, status) {//		console.log("statechanged: " + d.state);//	});	dtask.start();}

图片压缩

//压缩图片function compressImage(src,dst,quality,callback) {	plus.zip.compressImage({		src: src,		dst: dst,		quality:quality	},	function() {		console.log("Compress success!");		callback();	},	function(error) {		console.log("Compress error!");	});}//缩放图片function zoomImage(src,dst,width,callback) {	plus.zip.compressImage({		src: src,		dst: dst,		width: width	},	function() {		console.log("Compress success!");		callback();	},	function(error) {		console.log("Compress error!" + JSON.stringify(error));	});}

文件上传

/** * 上传文件 * @param {Object} url * @param {Object} filePath */function upload(url, filePath) {	var task = plus.uploader.createUpload(serverUrl + "/" + url, {		method: "POST"	}, function(t, status) {		// 上传完成		if(status == 200) {			alert("Upload success: " + t.url);		} else {			plus.nativeUI.toast("Upload failed: " + status);		}	});	task.addFile(filePath, {		key: "testdoc"	});	//task.addData( "string_key", "string_value" );	//task.addEventListener( "statechanged", onStateChanged, false );	task.start();}

获取图片的BASE64

function GetBase64Code(path) //path绝对路径{        var bitmap = new plus.nativeObj.Bitmap("test"); //test标识谁便取        // 从本地加载Bitmap图片        bitmap.load(path,function(){            var base4=bitmap.toBase64Data();            var datastr=base4.split(',',3)            if(datastr.length>1)            {               pics.push(datastr[1]);            }else            {               pics.push(datastr[0]);            }            console.log('加载图片：'+base4);        },function(e){            console.log('加载图片失败：'+JSON.stringify(e));        });}
