Is there any jquery build in function which does this?

Answer 1

No, there is no jQuery Built in function to do this. You can use the following function, found from this SO answer

function getParameterByName(name) {

    var match = RegExp('[?&]' + name + '=([^&]*)')
                    .exec(window.location.search);

    return match && decodeURIComponent(match[1].replace(/\+/g, ' '));

}

To get the q parameter just call it like

var qvalue = getParameterByName('q');

UPDATE

If you want to use this function by passing url instead of using current page's url modify the function like follwoing

function getParameterByName(name,url) {

    var match = RegExp('[?&]' + name + '=([^&]*)')
                    .exec(url);

    return match && decodeURIComponent(match[1].replace(/\+/g, ' '));

}

and then you can call it like

var qvalue = getParameterByName('q','www.test.com?q=1')
