Can we pass JSON as Custom Attributes.

[maks...@gmail.com]

I would like to know if JSON can be passed as Custom Attributes and can be accessed in the Polymer Element data binding?

[Eric Bidelman]

Yep. Be sure to hint the property type as an array/object.

See :

http://www.polymer-project.org/docs/start/usingelements.html#objectarray

and:

http://www.polymer-project.org/docs/polymer/polymer.html#binding-objects-and-arrays-to-attribute-values.

I am not successful. When i tried the below

<master-elem datee ='[{"name":"John"}, {"name":"Bob"}]'></master-elem>

and read the value as below - I am getting undefined but I am able to read the value from the Polymer construction or any events in it.

polymer-element name="master-elem" attributes="letters datee">
    <template>
        <template repeat="{{d in datee}}">
            <my-elem name={{d.name}}
                     valuee=true></my-elem>
        </template>
       
    </template>
    <script>

Can you please help?

In order to deserialize as an object, the `datee` must be an object. You can do this:
