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)  
}

Answer 2

No, because the query string is part of the URL. If you don't truly need to pass those values for the purposes of the server, you can include them in the history's state object itself, and then you can change just the state object with pushState(). For example:

history.pushState({value: 1, value2: 2}, "Title", 'page.php');
history.pushState({value: 1, value2: 'new value'}, "Title");

Answer 3

If what you're trying to do is change the URL without adding an additional entry to the history object, you might try replaceState.

history.replaceState({value: 1, value2: X}, "title", "page.php");
