Jquery的不過濾列表。它在查詢字符串中傳遞搜索詞作爲術語變量。爲遠程源的文檔是在這裏:http://api.jqueryui.com/autocomplete/#option-source
您需要根據項請求參數在你的處理器返回過濾後的數據。換句話說,改變了你的產品的處理程序,以更多的東西是這樣的:
class Products(webapp2.RequestHandler):
def get(self):
term = self.request.get('term', None)
self.response.headers['Content-Type'] = 'application/json'
data = ['cat', 'dog', 'bird', 'wolf']
if term:
data = [i for i in data if i.find(term) >= 0 ]
data = json.dumps(data)
self.response.out.write(data)
下面是一個基於jQuery開發的UI自動完成樣本的完整工作示例:
import webapp2
import json
class MainPage(webapp2.RequestHandler):
def get(self):
self.response.out.write("""
