我有div
id
是“carID”。
我需要做这样的事情:
magic(){
//Safe Html is imported previously in the component
document.getElementById('carID'): SafeHtml
}
基本上我需要的是将div的类型更改为SafeHtml
管
我有一个管道:
import { Pipe, PipeTransform } from '@angular/core';
import * as jQuery from 'jquery';
import { escape } from 'querystring';
import { TestExecutionComponent } from './test-execution/test-execution.component';
import { DomSanitizer, SafeHtml } from '@angular/platform-browser';
//import * as angular from '../angular.js';
//CAMBIAR a string
@Pipe({
name: 'formatXml'
})
export class FormatXmlPipe implements PipeTransform {
constructor(private sanitized: DomSanitizer) {}
testExecutionComponent: TestExecutionComponent;
transform(xml: String): SafeHtml {
var formatted = '';
var reg = /(>)(<)(\/*)/g;
xml = xml.replace(reg, '$1\r\n$2$3');
var pad = 0;
jQuery.each(xml.split('\r\n'), function (index, node) {
var indent = 0;
if (node.match(/.+<\/\w[^>]*>$/)) {
indent = 0;
} else if (node.match(/^<\/\w/)) {
if (pad != 0) {
pad -= 1;
}
} else if (node.match(/^<\w[^>]*[^\/]>.*$/)) {
indent = 1;
} else {
indent = 0;
}
var padding = '';
for (var i = 0; i < pad; i++) {
padding += ' ';
}
formatted += padding + node + '\r\n';
pad += indent;
});
var escaped = formatted.replace(/&/g, '&').replace(/</g, '<').replace(/>/g, '>').replace(/ /g, ' ').replace(/\n/g, '<br />');
// https://stackoverflow.com/questions/39240236/insert-xml-into-dom-in-angular-2
let safeEscaped = this.sanitized.bypassSecurityTrustHtml(escaped);
return safeEscaped;
//let safeEscaped = this.sanitized.bypassSecurityTrustHtml(escaped);
//return safeEscaped;
}
}
我将bypassSecurityTrustHtml
与字符串一起使用。
组件
<div id="carDiv" class="table-responsive">
<table class="table table-bordred table-striped ">
<tbody *ngIf="cars">
<tr *ngFor="let car of cars; let i = index;">
<td *ngIf="i==_rowToShow" [innerHTML]="car.ID| formatXml"></td>
</tr>
</tbody>
</table>
</div>
我的代码正在运行。我从HTML文件调用我的管道,我得到了答案。问题是当我在div
上打印时,字符串保持不变(没有格式)。
我读过我需要:
bypassSecurityTrustHtml
SafeHtml
我正在检查的帖子如下:Here
我已迈出第一步,所以我想现在我需要的是SafeHtml
Div
。我该怎么做?
答案 0 :(得分:1)
<强>更新强>
最后两行应为
let safeEscaped = this.sanitized.bypassSecurityTrustHtml(escaped);
return safeEscaped;
<强>原始强>
这可能会做你想要的事情
class MyComponent {
constructor(private sanitizer:DomSanitizer){}
magic(){
var safe = this.sanitizer.bypassSecurityTrustHtml(document.getElementById('carID').outerHTML);
}
}
但是根据获取的元素所包含的内容,这可能是安全明智的Harakiri,并且可能会出现。
