#1. Get text content from a fake element (not recommended)
const stripHtml = function (html) {
// Create new element
const ele = document.createElement('div');
// Set its HTML
ele.innerHTML = html;
// Return the text only
return ele.textContent || '';
};
This approach isn't recommended because it can cause a security issue if the input
`html`
consists of special tags, such as
`<script>`
. However, we can prevent the html from being executed by replacing the `div`
tag with `textarea`
:const stripHtml = function (html) {
const ele = document.createElement('textarea');
ele.innerHTML = html;
return ele.textContent || '';
};
#2. Use DOMParser
const stripHtml = function (html) {
const doc = new DOMParser().parseFromString(html, 'text/html');
return doc.body.textContent || '';
};
#3. Use template
The
`<template>`
tag holds a HTML content that is not to be rendered immediately. However, this is not supported on older browser such as IE 11.const stripHtml = function (html) {
const ele = document.createElement('template');
ele.innerHTML = html;
return ele.content.textContent || '';
};
