Question

.controller("testCtrl",function($scope){
  $scope.test = "123";
  var dbSize = 5 * 1024 * 1024; // 5MB
  //create db
  var db = openDatabase("Products", "", "Product Cart", dbSize, function() {
    console.log('db successfully opened or created');
  });
  db.transaction(function (tx) {
        tx.executeSql("CREATE TABLE IF NOT EXISTS product(ID INTEGER PRIMARY KEY ASC, productName TEXT, price TEXT , imgPath TEXT, isCart BIT)");
        tx.executeSql("INSERT INTO product(productName, price, imgPath, isCart) VALUES (?,?,?,?)",['testP','100','imgp','1']);
         $scope.testClick = function(){
            tx.executeSql('SELECT productName FROM product', [], function (tx, results) {
            var len = results.rows.length, i;
                for (i = 0; i < len; i++) {
                    console.log(results.rows.item(i).text);
                }
        });
  }

    });

 
})

这里我附上了我的控制器代码和HTML代码。当我点击按钮时出现此错误“无法在'SQLTransaction'上执行'executeSql'：不允许执行SQL。”。我怎样才能解决这个问题？谢谢
