我想插入一个标签,以便匹配Fab列表中的每个FAB图标,以确定正确的方法。我这样做的方式不起作用
<ion-fab left middle>
<button ion-fab color="dark">
<ion-icon name="arrow-dropup"></ion-icon>
<ion-label>here</ion-label>
</button>
<ion-fab-list side="top">
<button ion-fab>
<ion-icon name="logo-facebook"></ion-icon>
<ion-label>here</ion-label>
</button>
<button ion-fab>
<ion-icon name="logo-twitter"></ion-icon>
</button>
<button ion-fab>
<ion-icon name="logo-vimeo"></ion-icon>
</button>
<button ion-fab>
<ion-icon name="logo-googleplus"></ion-icon>
</button>
</ion-fab-list>
</ion-fab>

对于它的价值,我能够通过以下SCSS完成您的要求。
如果Ionic直接支持它,那就太好了,但是我无法找到任何表明它是内置的东西。
button[ion-fab] {
overflow: visible;
position: relative;
ion-label {
position: absolute;
top: -8px;
right: 40px;
color: white;
background-color: rgba(0,0,0,0.7);
line-height: 24px;
padding: 4px 8px;
border-radius: 4px;
}
contain: layout;
}
答案 1 :(得分:29)
setContentView(tv1);
类从.fab
更改为contain: strict
。
这是班级的最初方式:
contain: layout
因此,请在页面.scss文件中添加以下内容:
.fab {
-moz-appearance: none;
-ms-appearance: none;
-webkit-appearance: none;
appearance: none;
position: relative;
z-index: 0;
display: block;
overflow: hidden;
width: 56px;
height: 56px;
border-radius: 50%;
font-size: 14px;
line-height: 56px;
text-align: center;
text-overflow: ellipsis;
text-transform: none;
white-space: nowrap;
cursor: pointer;
transition: background-color, opacity 100ms linear;
background-clip: padding-box;
-webkit-font-kerning: none;
font-kerning: none;
-webkit-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;
contain: strict;
}
它将覆盖页面的默认.fab {
contain: layout;
}
类,它将起作用。

如果您使用的是离子4,这是给您的
ion-fab-button[data-desc] {
position: relative;
}
ion-fab-button[data-desc]::after {
position: absolute;
content: attr(data-desc);
z-index: 1;
right: 55px;
bottom: 4px;
background-color: var(--ion-color-dark);
padding: 9px;
border-radius: 15px;
color: white;
box-shadow: 0 3px 5px -1px rgba(0,0,0,0.2), 0 6px 10px 0 rgba(0,0,0,0.14), 0 1px 18px 0 rgba(0,0,0,0.12);
}
<ion-fab horizontal="end" vertical="bottom" slot="fixed">
<ion-fab-button color="primary" class="">
<ion-icon name="add"></ion-icon>
</ion-fab-button>
<ion-fab-list side="top">
<ion-fab-button color="primary" routerLink="/contacts/create" routerDirection="forward" data-desc="Create Contact">
<ion-icon name="person-add"></ion-icon>
</ion-fab-button>
<ion-fab-button color="primary" >
<ion-icon name="stats"></ion-icon>
</ion-fab-button>
<ion-fab-button color="primary" routerLink="/reminder/create" routerDirection="forward" data-desc="Create Reminder">
<ion-icon name="alarm"></ion-icon>
</ion-fab-button>

答案 3 :(得分:2)
Ionic 4/5接受的答案(图标旁边的标签)不再起作用。您必须使用::after
或item
之类的全局属性来使用data-
伪CSS样式。请参见下面的示例:
HTML:
<ion-fab vertical="bottom" horizontal="end">
<ion-fab-button>
<ion-icon name="add"></ion-icon>
</ion-fab-button>
<ion-fab-list side="top">
<ion-fab-button (click)="do1()" data-desc="Description 1">
<ion-icon name="contact"></ion-icon>
</ion-fab-button>
<ion-fab-button (click)="do2()" data-desc="Description 2">
<ion-icon name="person-add"></ion-icon>
</ion-fab-button>
</ion-fab-list>
</ion-fab>
SCSS:
ion-fab-button[data-desc] {
position: relative;
}
ion-fab-button[data-desc]::after {
position: absolute;
content: attr(data-desc);
z-index: 1;
right: 55px;
bottom: 4px;
background-color: var(--ion-color-primary);
padding: 9px;
border-radius: 15px;
color: white;
box-shadow: 0 3px 5px -1px rgba(0,0,0,0.2), 0 6px 10px 0 rgba(0,0,0,0.14), 0 1px 18px 0 rgba(0,0,0,0.12);
}

是的,你可以这样实现。
component.html
文件中。<ion-fab vertical="bottom" horizontal="end">
<ion-fab-button color="success">
<ion-icon name="alert-circle-outline"></ion-icon>
</ion-fab-button>
<ion-fab-list side="top">
<ion-fab-button (click)="callFunction()" data-desc="Sales" color="success">
<ion-icon name="cart-outline"></ion-icon>
</ion-fab-button>
<ion-fab-button (click)="callFunction()" data-desc="Payment" color="success">
<ion-icon name="cash-outline"></ion-icon>
</ion-fab-button>
<ion-fab-button (click)="callFunction()" data-desc="Edit" color="danger">
<ion-icon name="create-outline"></ion-icon>
</ion-fab-button>
</ion-fab-list>
</ion-fab>
在 component.css
文件中..
ion-fab-button[data-desc] {
position: relative;
}
ion-fab-button[data-desc]::after {
position: absolute;
content: attr(data-desc);
z-index: 1;
right: 50px;
bottom: 4px;
background-color: attr(color);
padding: 5px;
border-radius: 10px;
box-shadow: 0 3px 5px -1px rgba(0, 0, 0, 0.2), 0 6px 10px 0 rgba(0, 0, 0, 0.14), 0 1px 18px 0 rgba(0, 0, 0, 0.12);

选择的答案似乎在大多数情况下都有效,但是在某些iOS设备中,它没有采用variable
设置,从而导致标签未对齐。我不需要将标签作为可单击按钮的一部分,因此下面添加的FAB标签在iOS上可用。非常简单。
HTML
contain: layout;
CSS
<ion-fab top right edge>
<button ion-fab color="primary">
<ion-icon name="add"></ion-icon>
</button>
<ion-label>Scan</ion-label>
</ion-fab>
