CanJS Observable和键中的点 [英] CanJS Observable and dots in keys

问题描述

我的问题是在使用canJS Observable时，我不能在对象键中使用点，因为可以认为这里有一些嵌套。

My problem is while using canJS Observable I can't use dots in object keys, because can think that some nesting available here.

所以，假设我创建了新的可观察对象：

So let's say if I create new observable:

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

可能会失败并显示消息

can.Observe: Object does not exist

我无法创建只需使用

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

因为现在可以失败，并出现以下错误：

because now can fails with the following error:

TypeError: current._set is not a function

使用以下代码创建可观察对象

Creating observable using following code

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

工作正常，但我不需要嵌套，可以尝试嵌套将测试类放入可观察的 div 中。

works perfectly but I DON'T NEED nesting, and can tries to nest test-class into div inside observable.

所以，任何想法都可以

推荐答案

这确实是一个错误，并已在1.1.5版中修复。现在的一般规则是：

This was indeed a bug and has been fixed in version 1.1.5. The general rule now is:

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

将创建您期望的观察。将对象传递给 .attr ，例如

Will create the observe you expect. Passing an object to .attr like

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

还将 my.test 设置为属性。作为设置器传递，例如

Will also set my.test as the property. Passing it as a setter like

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

将设置 {my：{test：'testing'}} 。
