jquery - javascript find html with class and with nested -

-

इस स्टैकवॉवरफ्लो के लिए सरल निर्यात javscript फ़ंक्शन चलाना -

उदाहरण यहाँ:

हालांकि मैं इसे बदलना चाहता हूं, इसलिए यह केवल एक निश्चित वर्ग की पंक्तियों को प्राप्त कर लेता है, यही वह है जो मैंने अभी तक करने की कोशिश की है। 

  var $ rows = $ Table.find ('tr: has (td)'),   
 मेरा  
  var $ rows = $ table.find ('tr.hasClass ('शो'): है (टीडी) '),   
 मैं जेएस के बारे में कुछ नहीं जानता, जाहिरा तौर पर, इसलिए मदद की बहुत सराहना की जाती है।   
 < Div class = "post-text" itemprop = "text"> 
 आपको चयनकर्ता में  hasClass  का उपयोग करने की आवश्यकता नहीं है आपका कोड होना चाहिए:  
  var $ पंक्तियाँ = $ table.find ('tr.show:has (td)'),   
 जहां आपकी कक्षा नाम  शो  है JQuery और CSS में डॉट (। ) का अर्थ है  class  selector already।

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
