immutable chrome sqlite return objects

Question

I am using a sqlite DB as a storage system for a webapp. I been using the objects that are returned from queries directly in application. For example:

function g         


        

Answer 1

Building on Stepan's answer, but for people like me that want a quick fix from SO.
You can create another basic object and copy the sqlite row properties onto it.
Something like this:

var immutable_book = results.rows.item(0);
var book = {};
for (var prop in immutable_book) {
    if (immutable_book.hasOwnProperty(prop)) {
        book[prop] = immutable_book[prop];
    }
}

That goes in the _successCallback, and then later you can do this:

book.title=book.title+"more text"; // works now !

I came across this issue in iOS Safari, but in Chrome and Android web-kit browsers I was able to update properties of the returned row object directly.
