Ensure that aliasAs expressions are valid simple identifiers. These are still assigned to $scope in the same way
that they were previously, however now you won't accidentally create a property named "filtered.collection".
This change additionally restricts identifiers to prevent the use of certain ECMAScript reserved words ("null",
"undefined", "this" --- should probably add "super", "try", "catch" and "finally" there too), as well as certain
properties used by $scope or ngRepeat, including $parent, $index, $even, $odd, $first, $middle, or $last.

@name ngRepeat:badident
|

@fullName Invalid identifier expression
|
|
@description
|
|
|
|
Occurs when an invalid identifier is specified in an {@link ng.directive:ngRepeat ngRepeat} expression.
|
|
|
|
The {@link ng.directive:ngRepeat ngRepeat} directive's `alias as` syntax is used to assign an alias for the processed collection in scope.
|
|
|
|
If the expression is not a simple identifier (such that you could declare it with `var {name}`, or if the expression is a reserved name,
|
|
this error is thrown.
|
|
|
|
Reserved names include:
|
|
|
|
- `null`
|
|
- `this`
|
|
- `undefined`
|
|
- `$parent`
|
|
- `$even`
|
|
- `$odd`
|
|
- `$first`
|
|
- `$last`
|
|
- `$middle`
|
|
|
|
Invalid expressions might look like this:
|
|
|
|
```html
|
|
<li ng-repeat="item in items | filter:searchString as this">{{item}}</li>
|
|
<li ng-repeat="item in items | filter:searchString as some.objects["property"]">{{item}}</li>
|
|
<li ng-repeat="item in items | filter:searchString as resultOfSomeMethod()">{{item}}</li>
|
|
<li ng-repeat="item in items | filter:searchString as foo=6">{{item}}</li>
|
|
```
|
|
|
|
Valid expressions might look like this:
|
|
|
|
```html
|
|
<li ng-repeat="item in items | filter:searchString as collections">{{item}}</li>
|
|
<li ng-repeat="item in items | filter:searchString as filteredCollection">{{item}}</li>
|
|
```
