How to read query string value with JavaScript?
To read query string value from the current url with javascript you need to add a function in your head or body section. function getQueryStringValue ( key ) { return decodeURIComponent ( window . location . search . replace ( new RegExp ( "^(?:.*[&\\?]" + encodeURIComponent ( key ). replace ( /[\.\+\*]/ g , "\\$&" ) + "(?:\\=([^&]*))?)?.*$" , "i" ), "$1" )); } Then you can alert or console the value of your query string.
