history.pushState() change query values

Question

If I have a link that is being changed with the function history.pushState({}, \"\", link); where my link is for example page.php?value=1&

Answer 1

You can use this useful function to change a query string parameter value:

function updateParam(url, param, value)
{  
    var re = new RegExp(param+"(.+?)(&|$)","g");

    return url.replace(re, param+'='+value)  
}
