javascript - Jquery/Javascript 从窗口位置获取参数

Question

我的网址是:

http://localhost:3000/?sort=rating

参数sort是动态的，我想将其添加到另一个URL。

在我的 javascript 中，我有:

window.location.pathname + '.js?page=' + currentPage

如何在末尾添加 sort 参数？

示例:

window.location.pathname + '.js?page=' + currentPage + &sortparam

在这种情况下，它将是:

window.location.pathname + '.js?page=' + currentPage + '&sort=rating'

How can I get query string values in JavaScript?

就您而言:

function getParameterByName(name)
{
  name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
  var regexS = "[\\?&]" + name + "=([^&#]*)";
  var regex = new RegExp(regexS);
  var results = regex.exec(window.location.search);
  if(results == null)
    return "";
  else
    return decodeURIComponent(results[1].replace(/\+/g, " "));
}

var sortparam = getParameterByName("sort");
window.location.pathname + '.js?page=' + currentPage + '&sort='+sortparam
