javascript - How to pass to a component an attribute with variable and static parts in EmberJs? -


i'm trying pass link-to component style attribute. it's not default attributebinding, had reopen linkcomponent class , add 'style' attribute there.

ember.linkcomponent.reopen({   attributebindings: ['style'] });

doing that, can set following:

{{#link-to element.link element.param style="background: red;"}}text link{{/link-to}}

it render , see eye-burning link red background.

what i'm trying achieve apply image url background-image property on style attr.

{{#link-to element.link element.param style="background-image: url(element.background);"}}text link{{/link-to}}

but i'm getting variable name inside attribute.

i tried with:

  • element.background
  • ${element.background}
  • {{element.background}}
  • treat sum of string , variable parts "url("+element.background+")" breaks code compilation

i know seems computed property, , passing url , creating whole value inside class, or maybe passing value formatted on first place style=element.background trick, it's link-to helper i'd prefer keep listening style attribute , model holding url values.

any or idea broadly welcomed.

you can use concat helper,

style=(concat 'background-image: url(' element.background ');')
