# Samsung Samrt TV - save / load data

如果要儲存資料(ex: 使用者資訊…)建議使用 Samsung 的 file API 使用 HTML5 的 localStorage 在電視關機後會被清掉

File API Refer - Can I access a local file from JavaScript code? Refer - openCommonFile Refer - readAll

## example


var fileSystemObj = new FileSystem();

function save() {
    if (fileSystemObj.isValidCommonPath(curWidget.id) == 0){
        fileSystemObj.createCommonDir(curWidget.id);
    }
    var fileObj = fileSystemObj.openCommonFile(curWidget.id + '/testFile.data', 'w');
    fileObj.writeAll('test save');
    fileSystemObj.closeCommonFile(fileObj);
}
Main.save = save;

function read() {
    var file = fileSystemObj.openCommonFile(curWidget.id + '/testFile.data', 'r');
    var strResult = file.readAll();
}
Main.read = read;
