Add query string using pushstate

问题

I am doing something like below

if(history.pushState)
{
    var stateObject = { dummy: true };
    var url = window.location.protocol
        + "//"
        + window.location.host
        + window.location.pathname
        + '?myNewUrlQuery=1';
    history.pushState(stateObject, jQuery(document).find('title').text(), + url);
}

I am getting pathname correct, but getting query string as Nan. For example I am getting result like

http://example.com/mypage/Nan

Instead of

http://example.com/page/?myNewUrlQuery=1

Please tell me is it possible to add query string in URL using pushstate method. If yes, any working example will be extremely helpful.

Thanks in advance.

回答1:

+ url

You have a Unary plus operator before the url variable that converts it to a number. Since it isn't a string containing a number you get Not A Number instead. Remove the +.
