我正在尝试将我的SVG添加到加载创建功能,但是当我去查看它时,我看到它是一个空标记应该是什么.

我怎样才能让它渲染?我也将它复制到link的离子论坛上
我试图添加一个管道,使其在运行时安全,但也失败了.
我做了这样的内容:
- <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);
- }
- }
我也尝试过使用文件:
- 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 **
更改我的代码后,我意识到你不能在变量内部分配清洁剂的返回值,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.
解决方法
微调器内容必须是’安全html’,即你必须使用bypassSecurityTrustHtml.
在你的情况下尝试使用:
在你的情况下尝试使用:
- let loading = this.loadingCtrl.create({spinner: ' ',content: this.sanitizer.bypassSecurityTrustHtml(this.appConfig.customSpinner)
- })
检查这个related question.
这是我在Ionic 3应用程序中使用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);
- }
- }
希望能帮助到你.
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();
