[英]How to handle the back button functionality for Hybrid mobile application using cordova
[英]I want to create a sample project using Sqlite plugin (Cordova) in Hybrid Mobile Apllication?
我引用了https://github.com/litehelpers/Cordova-sqlite-storage中提到的代码。 没有生成数据库文件。 任何帮助,不胜感激。
document.addEventListener('deviceready', onDeviceReady, false);
function onDeviceReady() {
var db = window.sqlitePlugin.openDatabase({name: 'my.db', location: 'default'});
db.transaction(function(tx) {
tx.executeSql('DROP TABLE IF EXISTS test_table');
tx.executeSql('CREATE TABLE IF NOT EXISTS test_table (id integer primary key, data text, data_num integer)');
// demonstrate PRAGMA:
db.executeSql("pragma table_info (test_table);", [], function(res) {
console.log("PRAGMA res: " + JSON.stringify(res));
});
tx.executeSql("INSERT INTO test_table (data, data_num) VALUES (?,?)", ["test", 100], function(tx, res) {
console.log("insertId: " + res.insertId + " -- probably 1");
console.log("rowsAffected: " + res.rowsAffected + " -- should be 1");
db.transaction(function(tx) {
tx.executeSql("select count(id) as cnt from test_table;", [], function(tx, res) {
console.log("res.rows.length: " + res.rows.length + " -- should be 1");
console.log("res.rows.item(0).cnt: " + res.rows.item(0).cnt + " -- should be 1");
});
});
}, function(e) {
console.log("ERROR: " + e.message);
});
});
}
请提供默认的文件位置
var db = window.sqlitePlugin.openDatabase({name:'my.db',location:'abc.txt'});
