An article on getting URL parameters using JavaScript (IE, NS).

Sample Image


This is a JavaScript that helps you get the URL Parameters of a page..

Using the code

It's very easy to use the script. Just include the .js file into the page HTML code and execute it when you want.

<script language="javascript" src="scripts/getParams.js"></script>

The getParams.js, which is saved in the "scripts" folder in the project, includes the function getURLParameters() which splits the URL string after the first '?' character, and it puts the parameter names and values in separate arrays, which have the same length.

If no parameters are found in the URL string, the appropriate alert comes up.

Finally, I have configured the script in such a way, that if a parameter does not have any value, the alert that shows this parameter, displays "No value" for this parameter.

At the end, the function shows the parameter names and values one by one, in alert message boxes, as it is shown in the picture above.

Points of Interest

I was wondering if it is possible to use URL parameters in client only pages, because it is useful sometimes to handle information and data by this way.

So, I learned how to get the URL parameters of a web page by using only JavaScript and not any Server-Side programming language.

The script can be used in both Internet Explorer and Netscape browsers.
