history.pushState() change query values
提问by Grigor
If I have a link that is being changed with the function history.pushState({}, "", link);where my linkis for example page.php?value=1&value2=2Is there a way to just change the value2with pushState()function instead of changing the whole link?
如果我有一个正在使用history.pushState({}, "", link);我所在的函数更改的链接，link例如page.php?value=1&value2=2有没有办法只更改value2withpushState()函数而不是更改整个链接？

If what you're trying to do is change the URL without adding an additional entry to the history object, you might try replaceState.
如果您尝试做的是更改 URL 而不向历史记录对象添加其他条目，您可以尝试replaceState.
history.replaceState({value: 1, value2: X}, "title", "page.php");

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:
不，因为查询字符串是 URL 的一部分。如果您真的不需要为服务器传递这些值，您可以将它们包含在历史记录的状态对象本身中，然后您可以使用pushState(). 例如：
history.pushState({value: 1, value2: 2}, "Title", 'page.php');
history.pushState({value: 1, value2: 'new value'}, "Title");

You can use this useful function to change a query string parameter value:
您可以使用这个有用的函数来更改查询字符串参数值：
function updateParam(url, param, value)
{
var re = new RegExp(param+"(.+?)(&|$)","g");
return url.replace(re, param+'='+value)
}
