append to url and refresh page

Question

I am looking to write a piece of javascript that will append a parameter to the current url and then refresh the page - how can I do this?

Answer 1

Please check the below code :

/*Get current URL*/    
var _url = location.href; 
/*Check if the url already contains ?, if yes append the parameter, else add the parameter*/
_url = ( _url.indexOf('?') !== -1 ) ? _url+'¶m='+value : _url+'?param='+value;
/*reload the page */
window.location.href = _url;
