How can I get query string values in JavaScript

Question

Is there a plugin-less way of retrieving query string values via jQuery (or without)?

If so, how? If not, is there a plugin which can do so?

Hello @kartik,

You don't need jQuery for that purpose. You can use just some pure JavaScript:

function getParameterByName(name, url) {
    if (!url) url = window.location.href;
    name = name.replace(/[\[\]]/g, '\\$&');
    var regex = new RegExp('[?&]' + name + '(=([^&#]*)|&|#|$)'),
        results = regex.exec(url);
    if (!results) return null;
    if (!results[2]) return '';
    return decodeURIComponent(results[2].replace(/\+/g, ' '));
}

Hope it helps!!

Thank you!!

Hello niroj
why you'd make this a jQuery plugin when it doesn't have any jQuery specific code?

Hello @Pooja,

 If you don't have a framework your functions will just get spread across your code. If you extend jQuery you will have a scope for your functions, it won't be floating around somewhere in your code.
