I am using this block of code to manage query string parameters :
function UpdateQueryString(key, value, url) {
if (!url) url = window.location.href;
var re = new RegExp("([?&])" + key + "=.*?(&|#|$)(.*)", "gi");
if (re.test(url)) {
if (typeof value !== 'undefined' && value !== null)
return url.replace(re, '$1' + key + "=" + value + '$2$3');
else {
var hash = url.split('#');
url = hash[0].replace(re, '$1$3').replace(/(&|\?)$/, '');
if (typeof hash[1] !== 'undefined' && hash[1] !== null)
url += '#' + hash[1];
return url;
}
}
else {
if (typeof value !== 'undefined' && value !== null) {
var separator = url.indexOf('?') !== -1 ? '&' : '?',
hash = url.split('#');
url = hash[0] + separator + key + '=' + value;
if (typeof hash[1] !== 'undefined' && hash[1] !== null)
url += '#' + hash[1];
return url;
}
else
return url;
}
}
Function source : add or update query string parameter
I am calling the function, everything runs fine but the url on my browser is not changed. I used also Chrome console to check if the function was correctly called and the function is ok and retuns the expected value but the url remains unchanged.
Thanks for your help
