What is the best way to remove text using javascript?

Hey everyone! I am new to coding in javascript and I'm hoping for some help with stripping text. I have a string that is formatted like this:

<iframe src="http://embed.videokoo.com/61YVek?client_file_id=390856&width=720&height=480" style="width:720px;height:480px;border:0;margin:0;padding:0;"></iframe>

My goal is to remove everything except for the URL, so the final output should be:

http://embed.videokoo.com/61YVek?client_file_id=390856

Does anyone have suggestions on how I can achieve this?

javascript

Answer №1

To simplify the process, considering that your <iframe...> is essentially a string coming from a <textarea> and you consistently aim to match the identical http://embed.videokoo.com... URL, the solution isn't to remove sections of the string, but rather to find a substring using a regular expression:

var str = '<iframe src="http://embed.videokoo.com/61YVek?client_file_id=390856&width=720&height=480" style="width:720px;height:480px;border:0;margin:0;padding:0;"></iframe>'
    
var substring = str.match(/http:\/\/embed.videokoo.com\/\w+\?client_file_id=\d+/)

document.write(substring);
