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网址。
在我的javascript中我有:
window.location.pathname + '.js?page=' + currentPage
如何在最后添加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'

以下是您要找的内容:
How can I get query string values in JavaScript?
在你的情况下:
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

这是另外一个,稍微更通用的包装器:
function getParams() {
var params = window.location.search.substring(1).split('& '),
i = 0,
pair = null,
result = {};
while (pair = params[i++]) {
pair = pair.split('=');
result[pair[0]] = decodeURIComponent(pair[1]);
}
return result;
}
alert(getParams().page);

window.location.pathname + '.js?page=' + currentPage +
"&" + location.search.match(/(sort=.*?)&|$/)[1]
