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();
}

锁定屏幕方向

//竖屏
plus.screen.lockOrientation("portrait-primary");

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));});
}
