Using a prefix in ng-class to define a string

ng-class="{{'tabs-'+currentStyle.value}}"

ng-class="'tabs-'{{currentStyle.value}}"

ng-class="tabs-{{currentStyle.value}}"

My goal is to dynamically apply a class based on a value. I have experimented with the options above, but encountered this error:

Error: [$parse:syntax] Syntax Error: Token 'undefined' not a primary expression at column null of the expression [tabs-] starting at [tabs-].

What am I missing here?

All I want is for the result to be class="tabs-currentStyle.value" without needing to introduce an additional variable in the scope.

Answer №1

Here is another method that functions:

ng-class="['tabs-'+currentStyle.value]">

I tested this out in Dalorzo's virtual demonstration.

Answer №2

Perhaps you are attempting to achieve this:

ng-class="{true:'tabs-'+currentStyle.value}[true]"
