Paginierungskomponente basierend auf jQuery-Kapselung

Vorwort:

Da das Projekt einen Paging-Effekt erzielen musste, habe ich in der jQuery-Plug-in-Bibliothek danach gesucht, aber den gewünschten Effekt nicht gefunden, also habe ich Ich habe selbst eine Paging-Komponente gekapselt.

Idee:

Basiert hauptsächlich auf der vom Prototyp während der Initialisierung erstellten Paging-Vorlage und der anschließenden Bindung dynamischer Ereignisse, um den Paging-Effekt der Aktualisierung des DOM zu erzielen.

3. Die Komponente ruft

über window.pageInit= $.pageInit=pageInit auf, um die Initialisierung der Paging-Komponente abzuschließen.

Die offengelegten Schnittstellen sind:

1.container: DOM-Container, default.page

2.setPos: Von DOM platzierte HTML-Position, Standardtext

3.totalPages: Standardanzahl der Seiten, erforderlich, Standardwert null

4.totalLists: Standardgesamtzahl der Daten, erforderlich, Standardwert null

5.initPage: Aktuelle Seite, standardmäßige erste Seite

6.inputVal: Sprungseite, standardmäßig erste Seite

7.callBack: Ausgeführte Rückruffunktion, erforderlich, standardmäßig null

Effekt :

Fügen Sie die Funktionen hinzu, die Sie über die CallBack-Schnittstelle ausführen müssen, und führen Sie dynamisches DOM-Rendering nur durch, wenn „true“ erforderlich ist.
