您可以尝试自己解析 url 参数。例如:
蟒蛇/Django
from urlparse import urlparse, parse_qsl
full_url = ''.join([request.path, '?', request.META['QUERY_STRING']])
#example.com?q=Something&filter1=Test&filter1=New&filter2=Web&filter3=Mine
parameters = parse_qsl(urlparse(full_url)[4])
#[(u'q', u'Something'), (u'filter1', u'Test'), (u'filter1', u'New'), (u'filter2', u'Web'), (u'filter3', u'Mine')]
last_parameter = parameters[-1]
#(u'filter3', u'Mine')
Javascript
var params = window.location.search.split("&");
//["?q=Something", "filter1=Test", "filter1=New", "filter2=Web", "filter3=Mine"]
var last_param = params[params.length-1].replace("?","").split("=");
//["filter3", "Mine"]
此示例不使用 jQuery,并提供 url 解析的基本知识。有很多图书馆,可以为你做。
