Directives
Name | Description |
---|---|
|
Adds and removes CSS classes on an HTML element. |
|
Instantiates a single Component type and inserts its Host View into current View. NgComponentOutlet provides a declarative approach for dynamic component creation.
|
|
A structural directive that renders a template for each item in a collection. The directive is placed on an element, which becomes the parent of the cloned templates. |
|
A structural directive that conditionally includes a template based on the value of an expression coerced to Boolean. When the expression evaluates to true, Angular renders the template provided in a then clause, and when false or null, Angular renders the template provided in an optional else clause. The default template for the else clause is blank.
|
|
Adds / removes DOM sub-trees based on a numeric value. Tailored for pluralization. |
|
Creates a view that will be added/removed from the parent NgPlural when the given expression matches the plural expression according to CLDR rules. |
|
An attribute directive that updates styles for the containing HTML element. Sets one or more style properties, specified as colon-separated key-value pairs. The key is a style name, with an optional .<unit> suffix (such as 'top.px', 'font-style.em'). The value is an expression to be evaluated. The resulting non-null value, expressed in the given unit, is assigned to the given style property. If the result of evaluation is null, the corresponding style is removed.
|
|
A structural directive that adds or removes templates (displaying or hiding views) when the next match expression matches the switch expression. |
|
Provides a switch case expression to match against an enclosing ngSwitch expression. When the expressions match, the given NgSwitchCase template is rendered. If multiple match expressions match the switch expression value, all of them are displayed.
|
|
Creates a view that is rendered when no NgSwitchCase expressions match the NgSwitch expression. This statement should be the final case in an NgSwitch .
|
|
