我正在尝试将我的SVG添加到加载创建函数中,但是当我去查看它时,我看到的只是一个空标记应该是。

let loading = this.loadingCtrl.create({spinner: ' ',
            content: this.appConfig.customSpinner })

上面是我的创建代码,该变量是下面的SVG代码。

如何让它渲染?我还将它复制到了link

上的离子论坛

我尝试添加一个管道,使其在运行时安全,但也失败。

我做了这个内容:

<div [innerHTML]='appConfig.customSpinner | safe'></div>

这是我的烟斗:

import { Pipe, PipeTransform } from '@angular/core';
import { DomSanitizer } from '@angular/platform-browser';

@Pipe({name: 'safe'})
export class SafeHtml {
  constructor(private sanitizer:DomSanitizer){}

  transform(html:any):any {
    return this.sanitizer.bypassSecurityTrustHtml(html);
  }
}

我也试过使用文件:

let loading = this.loadingCtrl.create({spinner: 'hide', content:"<object data='assets/spinner.svg' type='image/svg+xml'></object>"})

这仍然会导致同样的问题。

NB **

在更改我的代码之后,我意识到你不能从变量内的清理程序中分配返回值,而是在类中声明一个声明的变量。一个我这样做我不再有TS类型错误和svg XML加载。

微调内容必须是安全的html&#39;,即您必须使用bypassSecurityTrustHtml。 在您的情况下尝试使用:

let loading = this.loadingCtrl.create({spinner: ' ',
        content: this.sanitizer.bypassSecurityTrustHtml(this.appConfig.customSpinner)
})

这是我在Ionic 3 app上的html5微调器的工作代码:

import { DomSanitizer } from '@angular/platform-browser';

constructor(private sanitizer: DomSanitizer){

getProgressBar(percentaje) {
    let html: string =  '<span style="text-align: center">Loading...'
    + Math.round(percentaje)+'%</span>'
    + '<br><progress value="' + percentaje + '" max="100"></progress>';
    return this.sanitizer.bypassSecurityTrustHtml(html);
    }

doSomething(){

    let loading = this.loadingCtrl.create({
       spinner: 'hide',
    });
    loading.data.content = this.getProgressBar(0);
    loading.present();

   //some stuff

   loading.data.content = this.getProgressBar(progress);
   }
}

希望它有所帮助。

使用svg更新:

let svg = `<svg width="100" height="100">
            <circle cx="50" cy="50" r="40" stroke="green" stroke-width="4" fill="yellow" />
          </svg>`;

this.safeSvg = this.sanitizer.bypassSecurityTrustHtml(svg);

let loading = this.loadingCtrl.create({
  spinner: 'hide',
  content: this.safeSvg,
});
loading.present();

可以找到工作代码at this git repository

你也可以在&#34; src / theme / variables.scss&#34;中覆盖加载器样式。 e.g。

    ion-loading {
        ion-backdrop {
            background-color: white !important;
        }
        .loading-wrapper {
            justify-content: center !important;
            opacity: 0.8 !important;
            background-color: white !important;
            width: 100% !important;
            height: 100% !important;
            max-width: 100% !important;
            max-height: 100% !important;
        }

        .spinner-crescent circle {
            stroke: green !important;
        }

        .spinner-ios line,
        .spinner-ios-small line {
            stroke: green !important;
        }
    }
