1、判断数据库是否打开

javascript 复制代码

	isOpen() {
		let open = plus.sqlite.isOpenDatabase({
			name: this.dbName,
			path: this.dbPath
		})
		return open;
	}

2、创建数据库(有就打开)

javascript 复制代码

openSqlite() {
		return new Promise((resolve, reject) => {
			plus.sqlite.openDatabase({
				name: this.dbName,
				path: this.dbPath,
				success(e) {
					resolve(e); 
				},
				fail(e) {
					reject(e);
				}
			})
		})
	}

3、关闭数据库

javascript 复制代码

closeSqlite() {
		return new Promise((resolve, reject) => {
			plus.sqlite.closeDatabase({
				name: this.dbName,
				success(e) {
					resolve(e);
				},
				fail(e) {
					reject(e);
				}
			})
		})
	}

4、执行sql

javascript 复制代码

createTable(dbTable, data) {
		return new Promise((resolve, reject) => {
			plus.sqlite.executeSql({
				name: this.dbName,
				sql: `CREATE TABLE IF NOT EXISTS ${dbTable}(${data})`,
				success(e) {
					resolve(e);
				},
				fail(e) {
					reject(e);
				}
			})
		})
	}
