Angular data binding object in value attribute of option in select

Question:

Tag: angularjs,select,ng-repeat,value

I have a select item which I'm populating using ng-repeat in option. I use angular's data binding to set the value of the selected item to my model. But for some reason the " in the json string are now turned into \" . Because of this I can't reach the attributes in the json string anymore later on in my code.

<select id="concepts" class="form-control"     ng-model='usecase.concepts'  multiple title='-Select one or more primary concepts-' data-width="auto" >
        <option  ng-repeat='concept in concepten' value='{{concept}}'>{{concept.name}}</option>
</select> 

Concept JSON string looks like this:

{"name":"Concept1","description":"beschrijving"}

but when I select an item in the select it looks like this:

{\"name\":\"Concept1\",\"description\":\"beschrijving\"}

I later on want to fill some dropdowns with the name attribute of the chosen concepts, but I can't reach the name attribute anymore because of the backslash. How can I fix this so value doesn't add backslashed to the JSON string?

remark: It works perfectly using ng-options instead of ng-repeat, but I'm trying to use the nya-bootstrap-select which I can't get to work with the ng-options tag


Answer:

I would not recommend to put whole JSON-Strings as Value in the select. If your description contains more text / html you might run into trouble. It might be better to set the selected concepts in a change handler like:

ng-change="updateSelectedConcepts()"

In the plunkr you can see, that the usecase.concepts contains the selected concepten-objects.
