我有一个项目清单:
我想用动画效果折叠起来,只显示一项:
如您所见,当前它折叠为一项,但是整个组件都没有折叠。
我目前只是将项目的不透明度设置为零:
的CSS
.slide-fade-hide {
transition: all 1.2s ease-out;
opacity: 0;
//height: 2em;
}
.slide-fade-show {
transition: all 1.2s ease-in;
opacity: 1;
//height: 2em;
}
html
<ion-list>
<ion-row>
<ion-col>
<div id="search">
<ion-searchbar class="ion-searchtext" id="ion-searchtext" [(ngModel)]="searchQueryText" (ionFocus)="focusSearch($event)" (change)="onChangeText($event)"
(ionClear)="onCancelText($event)" (ionInput)="onInputText($event)" placeholder="{{jobType === 0 ? favourite ? 'Market Favourites' : 'Market' : favourite ? 'Postings Favourites' : 'Postings'}}"
debounce="1"></ion-searchbar>
</div>
<!--<div id="pinButton"><button ion-button (click)="presentPopover()" color="primary"><ion-icon name="funnel"></ion-icon></button></div>-->
</ion-col>
</ion-row>
<!--<div *ngIf="showExtraSearch === true">-->
<div id="extra-filter-items" class="slide-fade-hide">

javascript
showExtraFilters(): void {
let extraItemsElement = document.getElementById('extra-filter-items');
if (extraItemsElement) {
extraItemsElement.className = "slide-fade-show";
}
}
hideExtraFilters(): void {
let extraItemsElement = document.getElementById('extra-filter-items');
if (extraItemsElement) {
extraItemsElement.className = "slide-fade-hide";
}
}
问题
这些项目仍然存在,它们只是透明的。
因此,如果我单击它们,它们仍然会响应。
而且,它们仍在占用空间,因此dom的其余部分仍在其下方。
题
如何允许具有动画效果的项目从1个项目切换到5个项目,就像它们上下滑动一样?同样,当它们起来时,它们还释放了下面的空间。
我确实看过this example(请参阅“滑动并淡入淡出”),但是正如您在上面看到的那样,这没有达到我所需要的。
谢谢
ps。我正在使用Ionic2,所以不想使用其他任何Javascript框架(如JQuery)(只是普通的javascript和css)。
最佳答案
您需要在CSS中使用height属性进行过渡
$(function(){
$("li").click(function(){
$(this).addClass("vanish");
})
});
.vanish {
height:0;
transition: 1s all linear;
opacity:0;
}
li {
height:2em;
opacity:1;
background:green;
}
