Angular 2 How Do You Render Html From A Json Response Without Displaying The Tags To The User Duplicate

When working with Angular 2, you might encounter a common question: how do you render HTML from a JSON response without showing the tags to the user? This is especially important for maintaining a clean and polished user interface. In this article, we'll dive into this topic and provide clear steps to help you achieve this in your Angular projects.

One approach to rendering HTML from a JSON response in Angular 2 without displaying the tags is to make use of the `innerHTML` property binding. By binding the JSON response to the `innerHTML` property of an HTML element, Angular will interpret the content as HTML, rendering it correctly without displaying the tags.

Here's a step-by-step guide to implement this in your Angular project:

Start by creating a component in your Angular project where you want to display the HTML content from the JSON response.

In the component's TypeScript file, import the necessary modules:

import { Component } from '@angular/core';

Next, define a variable in your component to hold the JSON response. For this example, let's assume we have a JSON response stored in a variable named `jsonData`, which contains HTML content.

jsonData: any = {
  htmlContent: '<h1>Welcome to Angular 2!</h1><p>This is a sample HTML content.</p>'
};

In your component's HTML template, bind the `innerHTML` property of an element to the `htmlContent` property from the JSON response. Here's how you can achieve this:

<div></div>

By binding the `innerHTML` property to the HTML content stored in `jsonData.htmlContent`, Angular will render the content as HTML without displaying the tags to the user.

It's important to note that using the `innerHTML` property binding can expose your application to potential security vulnerabilities, such as cross-site scripting (XSS) attacks. Make sure to sanitize any user-generated content before dynamically rendering it using the `innerHTML` property.

In Angular, you can utilize the `DomSanitizer` service to sanitize the HTML content before rendering it. Here's an example of how you can sanitize the HTML content using the `DomSanitizer` service:

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

constructor(private sanitizer: DomSanitizer) {}

getSafeHtmlContent(htmlContent: string): SafeHtml {
  return this.sanitizer.bypassSecurityTrustHtml(htmlContent);
}

In your component, call the `getSafeHtmlContent` method to sanitize the HTML content before binding it to the `innerHTML` property:

<div></div>

By sanitizing the HTML content using the `DomSanitizer` service, you can ensure that your Angular application remains secure while rendering HTML content from a JSON response.

In conclusion, rendering HTML from a JSON response in Angular 2 without displaying the tags can be achieved by utilizing the `innerHTML` property binding. Remember to sanitize user-generated content to prevent security risks and ensure a safe user experience in your Angular applications.
