jquery / Get only number after particular word

href="something.do?something_id=-1&something=u_container_id=6445194287^something=70a6c7ca4f9d52001cb17e918110c72f";
href1="something.do?something=u_container_id=7757033893";
var id = href1.substr(href1.lastIndexOf("=") + 1 , href1.length);

This work good for href1 but not for href. I need to make a code which will get only container_id value. It can be 10 digits or less or more but will be only numbers

You can use a regular expression to find all these container_id= parts. Then you can extract the digits for each match:

href.match(/container_id=\d+/g).forEach(function(item){
    var id = item.split('=')[1];
    console.log(id);
});

You can use match() with capturing group regex 

href = "something.do?something_id=-1&something=u_container_id=6445194287^something=70a6c7ca4f9d52001cb17e918110c72f";
href1 = "something.do?something=u_container_id=7757033893";
var id = href1.substr(href1.lastIndexOf("=") + 1, href1.length);

var id = href1.match(/container_id=(\d+)/)[1];

document.write(id);
