extract text between string - javascript

Question

I have a string:

<iframe src="keep-url" width="125" height="290" frameborder="0" scrolling="no"></iframe>

I want to remove all except:

keep-url

and using Javascript, jquery, with jsfiddle
Thank you.

Correct me, but if you remove everything from a string except "keep-url", then why not simply change the string to "keep-url", if the original string contains it? — Rob

I think, question should be how to get specific question from string. It should be resolved using regex — Nafiul Islam

Try this var src = document.getElementsByTagName("iframe")[0].getAttribute('src'); — Hassan Imam

My string just a pure text, it's not <iframe> tag, you can see jsfiddle.net/ducrat/yhq1v31e — my notmypt

You don't need to extract text from the string, you can get the src attribute from the element:

var src = $('<iframe src="keep-url" width="125" height="290" frameborder="0" scrolling="no"></iframe>').attr('src');

console.log(src);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Use jQuery to create the element (without adding to the document) and get the attrribute:

$src = $(theString).attr('src');
