Mobilny interfejs kątowy - obszary przewijalne
Na niektórych urządzeniach występują problemy z elementami pozycjonowanymi na stałe. Aby pracować z przewijalnymi obszarami, Mobile Angular UI wykorzystuje overflow: auto .
Szablon obszaru przewijalnego jest następujący -
<div class="scrollable">
<div class="scrollable-content">...</div>
</div>Dodawanie nagłówków i stopek w obszarach przewijanych
Dodając klasy css .scrollable-header / .scrollable-footer , dodamy stały nagłówek / stopkę do przewijalnego obszaru, który chcesz. Nie musisz martwić się o wysokość i umiejscowienie, css zajmie się wszystkim.
Szablon nagłówka / stopki pokazano poniżej -
<div class="scrollable">
<div class="scrollable-header"><!-- ... --></div>
<div class="scrollable-content"><!-- ... --></div>
<div class="scrollable-footer"><!-- ... --></div>
</div>Dyrektywy w obszarach przewijalnych
Poniżej przedstawiono dyrektywy, które są bardzo pomocne podczas pracy z przewijalnymi obszarami -
uiScrollTop- Do użycia, gdy chcesz coś zrobić, gdy przewijanie sięga do góry. Na przykład ui-scroll-top = "callyourfunc ()".
uiScrollBottom- Używany, gdy chcesz coś zrobić, gdy zwój sięga do dołu. Na przykład ui-scroll-bottom = "callyourfunc ()".
uiScrollableHeader- Używana, gdy chcesz coś zrobić, gdy przewijanie dotrze do nagłówka. Na przykład ui-scroll-header = "callyourfunc ()".
uiScrollableFooter- Używana, gdy chcesz coś zrobić, gdy przewijanie dotrze do stopki. Na przykład ui-scroll-footer = "callyourfunc ()".
Przykład dyrektywy uiScrollBottom -
<div class="scrollable">
<div class="scrollable-content section" ui-scroll-bottom="callyourfunc()">
<ul>
<li ng-repeat="a in lists">
{{a.name}}
</li>
</ul>
</div>
</div>Oto działający przykład obszarów przewijanych.
