In the previous example, we could "use the SQLite offline storage API to store the app's settings". We also show how to store the JSON we need in a local file in the example "How to dynamically modify the data in the Listmodel in the QML application and store it in JSON format". In this article, we will use the localstorage provided by Qtquick to store the data we need. To illustrate the problem, I'll start by creating a template based on the "QtQuic

The JSON data is stored locally and needs to be called json.stringify () to convert it to a string. When read out, call Json.parse () to convert the string to JSON format.such as when writing:var json_data = {id:12,name: "Yang", email: "[email protected]"}; Storage.setitem ("Json_data", Json.stringify (Json_data)); When reading:var json_data = Json.parse (Storage.getitem ("Json_data")); This article transferred from: http://blog.csdn.net/my_yang/article/details/7955523HTML5
