substring/regex to get a src value held in a string

Question

I have a string with the value:

var string = \"
Some plain text


        

Answer 1

One way to do it is to use regular expressions.

var str = "<img alt='' src='http://api.com/images/UID' /><br/>Some plain text<br/><a href='http://www.google.com'>http://www.google.com</a>";

var regex = /<img.*?src='(.*?)'/;
var src = regex.exec(str)[1];

console.log(src);
