|
| - * The callback will receive with an event containing the following information in `event.detail`:
|
| - *
|
| - * _onKeydown: function(event) {
|
| - * console.log(event.detail.combo); // KEY+MODIFIER, e.g. "shift+tab"

| - * console.log(event.detail.key); // KEY only, e.g. "tab"

|
| - * console.log(event.detail.keyboardEvent); // the original KeyboardEvent
|

|
| - * The `iron-iconset-svg` element allows users to define their own icon sets
|
| - * that contain svg icons. The svg icon elements should be children of the
|
| - * `iron-iconset-svg` element. Multiple icons should be given distinct id's.
|
| - *
|
| - * Using svg elements to create icons has a few advantages over traditional
|
| - * bitmap graphics like jpg or png. Icons that use svg are vector based so
|
| - * they are resolution independent and should look good on any device. They
|
| - * are stylable via css. Icons can be themed, colorized, and even animated.
|
| - *
|
| - * Example:
|
| - *
|
| - * <iron-iconset-svg name="my-svg-icons" size="24">
|
| - * <svg>
|
| - * <defs>
|
| - * <g id="shape">
|
| - * <rect x="12" y="0" width="12" height="24" />
|
| - * <circle cx="12" cy="12" r="12" />
|
| - * </g>
|
| - * </defs>
|
| - * </svg>
|
| - * </iron-iconset-svg>
|
| - *
|
| - * This will automatically register the icon set "my-svg-icons" to the iconset
|
| - * database. To use these icons from within another element, make a
|
| - * `iron-iconset` element and call the `byId` method
|
| - * to retrieve a given iconset. To apply a particular icon inside an
|
| - * element use the `applyIcon` method. For example:
|
| - *
|
| - * iconset.applyIcon(iconNode, 'car');

| -### Closing and canceling
|
| -
|
| -An overlay may be hidden by closing or canceling. The difference between close and cancel is user
|
| -intent. Closing generally implies that the user acknowledged the content on the overlay. By default,
|
| -it will cancel whenever the user taps outside it or presses the escape key. This behavior is
|
| -configurable with the `no-cancel-on-esc-key` and the `no-cancel-on-outside-click` properties.
|
| -`close()` should be called explicitly by the implementer when the user interacts with a control
|
| -in the overlay element. When the dialog is canceled, the overlay fires an 'iron-overlay-canceled'
|
| -event. Call `preventDefault` on this event to prevent the overlay from closing.
|
| -
|
| -### Positioning
|
| -
|
| -By default the element is sized and positioned to fit and centered inside the window. You can
|
| -position and size it manually using CSS. See `Polymer.IronFitBehavior`.
|
| -
|
| -### Backdrop
|
| -
|
| -Set the `with-backdrop` attribute to display a backdrop behind the overlay. The backdrop is
|
| -appended to `<body>` and is of type `<iron-overlay-backdrop>`. See its doc page for styling
|
| -options.
|
| -
|
| -In addition, `with-backdrop` will wrap the focus within the content in the light DOM.
|
| -Override the [`_focusableNodes` getter](#Polymer.IronOverlayBehavior:property-_focusableNodes)
|
| -to achieve a different behavior.
|
| -
|
| -### Limitations
|
| -
|
| -The element is styled to appear on top of other content by setting its `z-index` property. You
|
| -must ensure no element has a stacking context with a higher `z-index` than its parent stacking
|
| -context. You should place this element as a child of `<body>` whenever possible.

|
| - * `Use Polymer.IronValidatableBehavior` to implement an element that validates user input.
|
| - * Use the related `Polymer.IronValidatorBehavior` to add custom validation logic to an iron-input.
|
| - *
|
| - * By default, an `<iron-form>` element validates its fields when the user presses the submit button.
|
| - * To validate a form imperatively, call the form's `validate()` method, which in turn will
|
| - * call `validate()` on all its children. By using `Polymer.IronValidatableBehavior`, your
|
| - * custom element will get a public `validate()`, which
|
| - * will return the validity of the element, and a corresponding `invalid` attribute,
|
| - * which can be used for styling.
|
| - *
|
| - * To implement the custom validation logic of your element, you must override
|
| - * the protected `_getValidity()` method of this behaviour, rather than `validate()`.
|
| - * See [this](https://github.com/PolymerElements/iron-form/blob/master/demo/simple-element.html)
|
| - * for an example.
|
| - *
|
| - * ### Accessibility
|
| - *
|
| - * Changing the `invalid` property, either manually or by calling `validate()` will update the
|
| - * `aria-invalid` attribute.

|
| -
|
| -### Two-way binding
|
| -
|
| -By default you can only get notified of changes to an `input`'s `value` due to user input:
|
| -
|
| - <input value="{{myValue::input}}">
|
| -
|
| -`iron-input` adds the `bind-value` property that mirrors the `value` property, and can be used

|
| -
|
| - <input is="iron-input" bind-value="{{myValue}}">
|
| -
|
| -### Custom validators
|
| -
|
| -You can use custom validators that implement `Polymer.IronValidatorBehavior` with `<iron-input>`.
|
| -
|
| - <input is="iron-input" validator="my-custom-validator">
|

|
| -### Stopping invalid input
|
| -
|
| -It may be desirable to only allow users to enter certain characters. You can use the

| -`prevent-invalid-input` and `allowed-pattern` attributes together to accomplish this. This feature
|
| -is separate from validation, and `allowed-pattern` does not affect how the input is validated.
