Final answer:
To remove HTML tags from a JavaScript string, use the replace() function with a regular expression. The pattern /<[^>]*>/g will match.
Step-by-step explanation:
To remove HTML tags from a string in JavaScript, one common method is to use the replace() function combined with a regular expression (regex). Here's a short example:
var stringWithHtml = "";
var stringWithoutHtml = stringWithHtml.replace(/<[^>]*>/g, '');
console.log(stringWithoutHtml); // Outputs: Hello World!
This code snippet declares a variable stringWithHtml that contains HTML content. It uses the replace() function to find all sequences of characters that start with '<' and end with '>', including everything in between—represented by the regex pattern /<[^>]*>/g.
These sequences are then replaced with an empty string (effectively removing them), resulting in a stringWithoutHtml that contains only the text. Remember that while this method is handy for simple cases, it shouldn't be relied upon for security-related tasks such as sanitizing user input because it may not remove all types of malicious content embedded within HTML.
