Improve this Doc View Source ngInit
- directive in module ng
The ngInit
directive allows you to evaluate an expression in the current scope.
This directive can be abused to add unnecessary amounts of logic into your templates. There are only a few appropriate uses of
ngInit
, such as for aliasing special properties of
ngRepeat
, as seen in the demo below; and for injecting data via server side scripting. Besides these few cases, you should use
controllers rather than
ngInit
to initialize values on a scope.
Note: If you have assignment in
ngInit
along with a
filter
, make sure you have parentheses to ensure correct operator precedence:
<div ng-init="test1 = ($index | toString)"></div>
