javascript - How to bind paper-toggle-button state to its label - Polymer -


i have several paper-toggle-button elements receive checked state via iron-ajax get, bringing json data of true/false nature set toggles on/off respectively.

i have labels next buttons display toggled state also, these taking same data toggles themselves. however, change labels bound current state of toggle rather back-end json data.

is @ possible?

html

<paper-toggle-button id="approver"  checked$="{{current.approver}}">{{current.approver}}</paper-toggle-button> <paper-toggle-button id="askexpert"  checked$="{{current.askexpert}}">{{current.askexpert}}</paper-toggle-button> <paper-toggle-button id="autoconnect"  checked$="{{current.autoconnect}}">null{{current.autoconnect}}</paper-toggle-button> <paper-toggle-button id="beexpert"  checked$="{{current.beexpert}}">{{current.beexpert}}</paper-toggle-button>

you're using attribute binding checked (i.e., checked$="{{flag}}"), checked property, should use property binding (i.e., checked="{{flag}}") proper data-binding notifications. note removed $ binding:

<paper-toggle-button id="approver"  checked="{{current.approver}}">{{current.approver}}</paper-toggle-button> <paper-toggle-button id="askexpert"  checked="{{current.askexpert}}">{{current.askexpert}}</paper-toggle-button> <paper-toggle-button id="autoconnect"  checked="{{current.autoconnect}}">{{current.autoconnect}}</paper-toggle-button> <paper-toggle-button id="beexpert"  checked="{{current.beexpert}}">{{current.beexpert}}</paper-toggle-button>

demo

i believe behavior you're seeking achieved fixing binding type indicated above.

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
