ion-refresher

Contents

RefresherはContentコンポーネント引っ張って更新する機能を提供します。 ユーザーはより多くのデータを取得するために、 タッチ操作でリストを引っ張って更新できます。

データはRefresherの外部のイベントで更新すべきです。 一回の非同期処理が完了すれば、complete()を呼び出すことで、 Refresherも終了するべきです。

プロパティ

closeDuration

Description

Time it takes to close the refresher.

Attributeclose-duration
Typestring
Default'280ms'

disabled

Description

If true, the refresher will be hidden.

Attributedisabled
Typeboolean
Defaultfalse

pullFactor

Description

How much to multiply the pull speed by. To slow the pull animation down, pass a number less than 1. To speed up the pull, pass a number greater than 1. The default value is 1 which is equal to the speed of the cursor. If a negative value is passed in, the factor will be 1 instead.

For example: If the value passed is 1.2 and the content is dragged by 10 pixels, instead of 10 pixels the content will be pulled by 12 pixels (an increase of 20 percent). If the value passed is 0.8, the dragged amount will be 8 pixels, less than the amount the cursor has moved.

Attributepull-factor
Typenumber
Default1

pullMax

Description

The maximum distance of the pull until the refresher will automatically go into the refreshing state. Defaults to the result of pullMin + 60.

Attributepull-max
Typenumber
Defaultthis.pullMin + 60

pullMin

Description

The minimum distance the user must pull down until the refresher will go into the refreshing state.

Attributepull-min
Typenumber
Default60

snapbackDuration

Description

Time it takes the refresher to to snap back to the refreshing state.

Attributesnapback-duration
Typestring
Default'280ms'

イベント

NameDescription
ionPullEmitted while the user is pulling down the content and exposing the refresher.
ionRefreshEmitted when the user lets go of the content and has pulled down further than the `pullMin` or pulls the content down and exceeds the pullMax. Updates the refresher state to `refreshing`. The `complete()` method should be called when the async operation has completed.
ionStartEmitted when the user begins to start pulling down.

メソッド

cancel

Description

Changes the refresher's state from refreshing to cancelling.

Signaturecancel() => Promise<void>

complete

Description

Call complete() when your async operation has completed. For example, the refreshing state is while the app is performing an asynchronous operation, such as receiving more data from an AJAX request. Once the data has been received, you then call this method to signify that the refreshing has completed and to close the refresher. This method also changes the refresher's state from refreshing to completing.

Signaturecomplete() => Promise<void>

getProgress

Description

A number representing how far down the user has pulled. The number 0 represents the user hasn't pulled down at all. The number 1, and anything greater than 1, represents that the user has pulled far enough down that when they let go then the refresh will happen. If they let go and the number is less than 1, then the refresh will not happen, and the content will return to it's original position.

SignaturegetProgress() => Promise<number>
