  • @Ashok do you have a string or a HTML element can you please clarify – Vivek Gupta May 29 '15 at 08:46

    before moving forward do check if your string is valid or not. It should be var srcString = ""; OR var srcString1 = ""; – Newinjava May 29 '15 at 08:49
  • If you have a `string` of HTML that contains `"` characters, you'll need to either escape them (eg: `" – Alex McMillan May 29 '15 at 08:52

You can use a regular expression to pull the src from your string like so:

var myString = '<iframe width="420" height="315" src="https://www.youtube.com/embed/DgPO56ImqUA?showinfo=1" frameborder="0" allowfullscreen></iframe>';
var regex = /<iframe.*?src="(.*?)"/;

var src = regex.exec(myString)[1];

console.log(src);

Give a name to your frame such as

"name="frame1" width=..... />"

then use this alert(document.frames['frame1'].location.href);
