I have content in a meta tag.

<meta property="video" content="initialver=1.0" />

I get the content in this tag using getAttribute("content"). Then I have a string: initialver=1.0. My need is getting "1.0". How can I do this without using split() ?

Reset to default 1 
var str = "initialver=1.0";
var result = str.substring(11);

You can use regex and match to do this

var x = "initialver=1.0".match(/\d+$|\d+\.\d+$/)[0]
