ngTrueValue and ngFalseValue now support parsed expressions which the parser determines to be constant values.
BREAKING CHANGE:
Previously, these attributes would always be treated as strings. However, they are now parsed as
expressions, and will throw if an expression is non-constant.
To convert non-constant strings into constant expressions, simply wrap them in an extra pair of quotes, like so:
<input type="checkbox" ng-model="..." ng-true-value="'truthyValue'">

@description
|
|
|
|
Some attributes used in conjunction with ngModel (such as ngTrueValue or ngFalseValue) will only
|
|
accept constant expressions.
|
|
|
|
Examples using constant expressions include:
|
|
|
|
```
|
|
<input type="checkbox" ng-model="..." ng-true-value="'truthyValue'">
|
|
<input type="checkbox" ng-model="..." ng-false-value="0">
|
|
```
|
|
|
|
Examples of non-constant expressions include:
|
|
|
|
```
|
|
<input type="checkbox" ng-model="..." ng-true-value="someValue">
|
|
<input type="checkbox" ng-model="..." ng-false-value="{foo: someScopeValue}">
|
|
```
