How to escape a filter variable in AngularJS?

Question

I want to escape the single quotes in the unique filter in angular but I can't, I've tried it in the following ways. If the field wouldn't have a hyphen I could do attrbutes.displayname and it will work (I've tried it), but I have a hyphen...

Example:

<select ng-model="style" ng-options="block.attributes['display-name'] for (blockName, block) in styleBlocks | unique:'attributes[\'display-name\']'">

<select ng-model="style" ng-options="block.attributes['display-name'] for (blockName, block) in styleBlocks | unique:'attributes[\\'display-name\\']'">

why you don't create a function in your controller or create a custom filter for this complex queries, it would be cleaner. Don't you think? — Dalorzo

Thanks for the idea, I prefer to use standard and well-tested functionalities. — Chexpir

A $filter, as @Dalorzo suggests, is in fact the standard and well-tested (and maintainable, and readable, and....) way to do anything other than the most basic filtering. — Daniel Beck

Use the Unicode escape \u0027 for single quotes:

'attributes[\u0027display-name\u0027]'
