ngClass
(directive in module ng
)
The ngClass allows you to set CSS class on HTML element dynamically by databinding an
expression that represents all classes to be added.
The directive won't add duplicate classes if a particular class was already set.
When the expression changes, the previously added classes are removed and only then the new classes are added.
<ANY ng-class="{expression}">
...
</ANY>
as class<ANY class="ng-class: {expression};">
...
</ANY>
ngClass – {expression} –
Expression to eval. The result of the evaluation can be a string representing space delimited class names, an array, or a map of class names to boolean values.
