How to Safely Decode Escaped URL Parameters in jQuery?
Decoding Escaped URL Parameters in jQuery
Web applications often retrieve and use URL parameters for various purposes. However, dealing with escaped characters in URL parameters can lead to JavaScript errors. This article discusses a jQuery-based solution to retrieve and decode escaped URL parameters without encountering such errors.
To retrieve and decode escaped URL parameters, we can modify the following jQuery function:
$.getUrlParameter = function(name) { var decodedValue = decodeURI( (RegExp(name + '=' + '(.+?)(&|$)').exec(location.search)||[,null])[1] ); return decodedValue; };
The RegExp function constructs a regular expression to search for the URL parameter with the specified name. The location.search property contains the query string portion of the current URL.
The result of the exec() function is an array, with the first element containing the matched string. The second element is a capturing group that contains the value of the URL parameter.
To decode the value before returning it, the decodeURI() function is used. This function decodes any percent-encoded characters in the parameter value.
Using this function, we can retrieve and decode escaped URL parameters in jQuery. For example:
var searchTerm = $.getUrlParameter('search');
The searchTerm variable will now contain the decoded value of the search parameter. If the parameter value was ���, the searchTerm variable would contain the value æøå.
