How to extract some information from a link in JavaScript by using regex pattern?

Question

Here is a example of my link:

var eg="http://abcd.efgh.com/ar/1/55242/1?lt=9&adtype=3&pubid=5574988682&toolid=10001&campid=5337040086&customid=&uq=HO+scale+scenery&sellerId=&ex_kw=&sortBy=1&catId=&minPrice=&maxPrice=&laction=_self&ltext=Scenery&n3y=1&v1e=1&u7v=1&a3h=1&def=a3h&ig=1&mpt=366074929"

I want pubid and campid in variables by using regex pattern.

var pubid=5574988682
var campid=5337040086

Please share the code & logic that you have tried and got stuck. Thanks! — palaѕн, Sep 21 '17 at 06:09
It is worth noting that regex questions without any attempt whatsoever are posted frequently onto Stack Overflow, and you may get a poor reception when making such posts, given that people will think you're asking them to do your work.

you can try like this

// Read a page's GET URL variables and return them as an associative array.
function getUrlVars()
{
    var vars = [], hash;
    var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
    for(var i = 0; i < hashes.length; i++)
    {
        hash = hashes[i].split('=');
        vars.push(hash[0]);
        vars[hash[0]] = hash[1];
    }
    return vars;
}

above code taken form : http://jquery-howto.blogspot.in/2009/09/get-url-parameters-values-with-jquery.html

You could do this:

var queryDict = {}
eg.search.substr(1).split("&").forEach(function(item) {queryDict[item.split("=")[0]] = item.split("=")[1]})

And then:

queryDict.pubid
=> 5574988682

queryDict.campid
=> 5337040086

You should try

regex = /.*&pubid=([\w-]{10}).*&campid=([\w-]{10})&.*/; //Regex

url = 'http://abcd.efgh.com/ar/1/55242/1?lt=9&adtype=3&pubid=5574988682&toolid=10001&campid=5337040086&customid=&uq=HO+scale+scenery&sellerId=&ex_kw=&sortBy=1&catId=&minPrice=&maxPrice=&laction=_self&ltext=Scenery&n3y=1&v1e=1&u7v=1&a3h=1&def=a3h&ig=1&mpt=366074929'; //Your URL

pubid = url.match(regex)[1];  //Get your pubid from first parameter
campid = url.match(regex)[2];   //Get your campid from second parameter</code>

You will get pubid = 5574988682 and campid=5337040086

For camp id RegEx is

(campid=)(\d)+

For pubid RegEx is

(pubid=)(\d)+

Where pubid= and campid= are strings and

\d---->Matches any digit character (0-9). Equivalent to [0-9].

+----->Matches 1 or more of the preceding token.
