Complex label for ng-options

Complex label for ng-options


Using ng-options is always somewhat cumbersome to me. When I have it written it’s perfectly fine, but every time I need to write it from scratch I have to take a look to docs or tutorials, to recall syntax.
Basic usage example with array, which is most frequently seen is:
ng-options="item.name for item in arrayOfItems"
How to get somewhat more complex label? Combintation of item fields like for example item.namewith item.surname
First trials with spaces and brackets failed, but eventually I find out quite obvious solution with a + mark:
ng-options="item.name+' - '+item.surname for item in arrayOfItems"
results in eg. John - Smith label. That’s how we can define pretty complex labels composed of many item fields if we need.
