SQLite的离子返回错误

Question

I'm using Firefox and Chrome for development. I installed the sqlite plugin but there's always error when firing openDB command on:

firefox(TypeError: n.sqlitePlugin is undefined ng-cordova.min.js (line 9, col 19046))

and

chrome(Uncaught TypeError: Cannot read property 'openDatabase' of undefined ng-cordova.min.js:9ng-cordova.min.js:9)

I don't know what did I do wrong. Please help.

Answer 1

SQlite plugin will be activated while you are running the application in mobile and it will not be available in browsers. Try running your app in mobile and check.

Answer 2

While in the browser check for the existence of sqlite if not present then default to webSQL , the code could be something like this , (based omn the framework u are using it would change)

 if(window.sqlitePlugin !== undefined) {
        console.log('opening sqlite DB ');
        db = window.sqlitePlugin.openDatabase("MyDB");
    } else {
        console.log('opening Web SQL DB ');
        db = window.openDatabase("MyDB", "1.0", "Cordova Demo", 200000);
    }
