AngularJS: ng-show / ng-hide -


i trying show / hide html using ng-show , ng-hide functions provided angularjs.

according documentation, respective usage these functions follows:

nghide – {expression} - if expression truthy element shown or hidden respectively. ngshow – {expression} - if expression truthy element shown or hidden respectively.

this works following usecase:

<p ng-hide="true">i'm hidden</p> <p ng-show="true">i'm shown</p>

however, should use parameter object expression ng-hide , ng-show given correct true/false value values not treated boolean return false:

source

<p ng-hide="{{foo.bar}}">i shown, or hidden</p> <p ng-show="{{foo.bar}}">i shown, or hidden</p>

result

<p ng-hide="true">i should hidden i'm shown</p> <p ng-show="true">i should shown i'm hidden</p>

this either bug or not doing correctly.

i cannot find relative information on referencing object parameters expressions hoping better understanding of angularjs might able me out?

the foo.bar reference should not contain braces:

<p ng-hide="foo.bar">i shown, or hidden</p> <p ng-show="foo.bar">i shown, or hidden</p>

angular expressions need within curly-brace bindings, angular directives not.

see understanding angular templates.
