I am looking to display smaller text on my website. I have considered creating a custom pipe to truncate strings, but in my situation it's not applicable. Here's what I'm dealing with:
<p [innerHTML]="aboutUs"></p>
Due to the tags present in the text coming from the backend, using a custom pipe is not an option for me. I need to use [innerHtml] to render the content correctly. Any advice would be appreciated.
To create a custom function in TypeScript that truncates text, you can use the following code:
truncateChar(text: string): string {
let charlimit = 100;
if(!text || text.length <= charlimit )
{
return text;
}
let without_html = text.replace(/<(?:.|\n)*?>/gm, '');
let shortened = without_html.substring(0, charlimit) + "...";
return shortened;
}
In your HTML file, you can call this function like so:
<div [innerHTML]="truncateChar(aboutUs)"></div>
It's best to avoid repeatedly calling a method from an HTML template, especially if the result is static or doesn't change frequently. This can lead to unnecessary processing.
Instead, consider calling the truncateChar method (found in @Sajeetharan's answer) from ngOnInit, ngOnChange, or any other relevant function where you update the aboutUs variable. Save the result in a separate variable within that component.
Then, utilize this variable in your template rather than directly calling the method every time.
