[英]Ionic LoadingController css
I am using Ionic3, and have a LoadingController
.我正在使用 Ionic3,并且有一个
LoadingController
。
this.loading = this.loadingCtrl.create({
content: '',
spinner: 'dots'
});
Question题
Is it possible to remove the white background behind the the dots?是否可以去除点后面的白色背景? ie Just have the dots over the backdrop.
即只是在背景上有点。
As you can see from the Ionic Documentation , there is an cssClass
option that can be used to do custom styling.正如您从Ionic 文档中看到的,有一个
cssClass
选项可用于进行自定义样式。 However, I am not sure what css to apply to the LoadingController
.但是,我不确定将什么 css 应用于
LoadingController
。
UPDATE更新
Adding the following to variables.scss
:将以下内容添加到
variables.scss
:
$loading-md-background: transparent;
But how do I remove the box?但是我如何移除这个盒子?
custom this color in your src/theme/variables.scss
在
src/theme/variables.scss
自定义此颜色
available variables: https://ionicframework.com/docs/api/components/loading/LoadingController/#sass-variables可用变量: https : //ionicframework.com/docs/api/components/loading/LoadingController/#sass-variables
$loading-ios-background: transparent;
$loading-md-background: $loading-ios-background;
$loading-wp-background: $loading-ios-background;
to remove box-shadow on android, add one more variable:要在 android 上删除 box-shadow,再添加一个变量:
$loading-md-box-shadow: none;
or add your class to cssClass
:或将您的课程添加到
cssClass
:
this.loading = this.loadingCtrl.create({
content: '',
spinner: 'dots',
cssClass: 'my-loading-class'
});
and style:和风格:
============================ ============================
UPDATE: IONIC 3更新:离子 3
ion-loading.my-loading-class {
.loading-wrapper {
background: transparent;
box-shadow: none;
}
}
============================ ============================
IONIC 2离子 2
.loading-ios,
.loading-md,
.loading-wp {
.my-loading-class {
background-color: transparent;
box-shadow: none;
}
}
Tiep Phan's solution didn't work for me, so please see the example below for a working solution as of Ionic version 3.19.0: Tiep Phan 的解决方案对我不起作用,因此请参阅下面的示例以了解 Ionic 版本 3.19.0 的工作解决方案:
const LOADING = this.loadingCtrl.create({
cssClass: 'transparent',
});
ion-loading.transparent {
.loading-wrapper {
background: transparent;
box-shadow: none;
.spinner-crescent circle {
stroke-width: 8px;
}
}
}
Please note that I have optionally increased the stroke width of the Android loading spinner to make it slightly more visible.请注意,我有选择地增加了 Android 加载微调器的笔触宽度,以使其更加明显。
This works for me with Ionic 4 and 5 for Android and iOS (using mode:'md' ):这对我适用于 Android 和 iOS 的 Ionic 4 和 5(使用mode:'md' ):
import { Injectable } from '@angular/core';
import { LoadingController } from '@ionic/angular';
import { LoadingOptions } from '@ionic/core';
@Injectable({
providedIn: 'root'
})
export class LoadingService {
constructor(public loadingController: LoadingController) { }
async present() {
// Dismiss all pending loaders before creating the new one
await this.dismiss();
let options: LoadingOptions = {
message: '<ion-img src="/assets/imgs/spinner.svg" alt="loading..."></ion-img>',
cssClass: 'custom-loading',
translucent: true,
showBackdrop: true,
spinner: null,
mode: 'md',
keyboardClose: true
};
await this.loadingController
.create(options)
.then(res => {
res.present();
});
}
/**
* Dismiss all the pending loaders, if any
*/
async dismiss() {
while (await this.loadingController.getTop() !== undefined) {
await this.loadingController.dismiss();
}
}
}
and then in global.scss:然后在 global.scss 中:
.custom-loading {
--background: none;
.loading-wrapper{
box-shadow: none !important;
-webkit-box-shadow: !important;
}
}
// this how to apply custom style or replace the loading icon with your desired one
//.ts
this.loading = this.loadingCtrl.create({
spinner: 'hide',
cssClass: 'custom-spinner',
// message:"hello",
content: `
<div class="custom-spinner-container">
<div class="custom-spinner-box">
<img src="assets/img/LOADING-.gif" style="max-width: 100%;
width: 140px !important;"/>
</div>
</div>`,
// duration:
})
//app.css
.custom-spinner {
.loading-wrapper{
background: transparent !important;
box-shadow: unset !important;
}
}
import { Injectable } from '@angular/core';
import { LoadingController } from '@ionic/angular';
@Injectable({
providedIn: 'root'
})
export class LoadingService {
constructor(public loadingController: LoadingController) { }
isLoading: boolean = false;
async present() {
this.isLoading = true;
return await this.loadingController.create({
spinner: null,
duration: 5000,
message: '<ion-img src="assets/images/loader-banorte.gif" ></ion-img>',
translucent: false,
cssClass: 'banorte-loading',
showBackdrop: true,
mode: 'md',
keyboardClose: false,
backdropDismiss: true
}).then(a => {
a.present().then(() => {
console.log('presented');
if (!this.isLoading) {
a.dismiss().then(() => console.log('abort presenting'));
}
});
});
}
async dismiss() {
this.isLoading = false;
return await this.loadingController.dismiss().then(() => console.log('dismissed'));
}
}
