How to usereplace() function in Javascript
The ‘<‘, ‘</’, ‘>’, can be used to identify a word as an HTML tag in a string. The following examples show how to strip out HTML tags using replace() function and a regular expression, which identifies an HTML tag in the input string. A regular expression is a better way to find the HTML tags and remove them easily.
Example: In this example we will strip out HTML tag with above method..
function removeTags(str) {
if ((str === null) || (str === ''))
return false;
else
str = str.toString();
// Regular expression to identify HTML tags in
// the input string. Replacing the identified
// HTML tag with a null string.
return str.replace(/(<([^>]+)>)/ig, '');
}
console.log(removeTags(
'<html>Welcome to w3wiki.</html>'));;
Output:
Welcome to w3wiki.
How to remove HTML tags from a string using JavaScript ?
In JavaScript, there are several methods available to remove HTML tags from a string. One common approach is to utilize the replace() function along with regular expressions to strip out the tags. Additionally, you can leverage properties such as .textContent and .innerText from the HTML DOM to achieve the same result.
HTML tags come in two forms: opening tags and closing tags. Understanding this distinction is crucial when parsing and manipulating HTML content.
- Opening tag: It starts with a ‘<‘, followed by an HTML keyword, and ends with a ‘>‘. <html>, <br>, <title> are some examples of HTML opening tags.
- Closing tag: It starts with a ‘</‘, followed by an HTML keyword, and ends with a ‘>‘.</html>, </title> are examples of HTML closing tags.
