How Can I Decode Escaped URL Parameters in JavaScript using jQuery?

Decoding Escaped URL Parameters with jQuery

In certain scenarios, you may encounter URL parameters containing escaped characters, leading to JavaScript errors upon retrieval. If you don't have server access to modify the parameter encoding, consider utilizing this jQuery plugin to retrieve and decode the parameters seamlessly.

Implementation:

The following jQuery plugin effectively handles escaped URL parameters:

function getURLParameter(name) {
    return decodeURI(
        (RegExp(name + '=' + '(.+?)(&|$)').exec(location.search)||[,null])[1]
    );
}

Usage:

To utilize this plugin, simply pass the name of the URL parameter you wish to retrieve as an argument to the getURLParameter function, as seen below:

var parameterValue = getURLParameter("search");

In the example provided, the parameter with the name "search" is retrieved and its decoded value is assigned to the parameterValue variable.

This plugin ensures that the retrieved URL parameters are properly decoded, preventing JavaScript errors and enabling seamless access to the parameter values, regardless of their encoding.
