Experience the power of CanJS Observable data objects with the added feature of

When working with canJS Observable, I encountered an issue where I cannot use dots in object keys because canJS interprets them as nesting. For example, if I try to create a new observable like this:

var obs = new can.Observe( { "div.test-class": { "color": "#000000;" } } );

canJS fails with the message:

can.Observe: Object does not exist

Similarly, creating an observable without dots results in another error:

var obs = new can.Observe( { ".test-class": { "color": "#000000;" } } );

This time, canJS throws the following error:

TypeError: current._set is not a function

One workaround is to create the observable like this:

var obs = new can.Observe( { "div": {}, "div.test-class": { "color": "#000000;" } } );

Although this solution works, it introduces unnecessary nesting that I do not need. Can anyone suggest a better approach to achieve what I need?

Answer №1

This issue was clearly identified as a bug but has since been resolved in version 1.1.5. Moving forward, the new rule is:

var obs = new can.Observe( { "div": {}, "div.test-class": { "color": "#000000;" } } );

With this code, you will achieve the desired result. When using .attr with an object like so:

obs.attr({ 'my.test': 'testing' });

The property my.test will be set accordingly. Alternatively, setting it as a key-value pair like:

obs.attr('my.test', 'testing');

Will result in { my: { test: 'testing' } }.
