javascript - Issue with setTimeout in ajax based polling using jquery -

-

इस सवाल का पहले से ही एक उत्तर है: < / P>

  • 3 जवाब

मेरे कोड में मुझे ज़रूरत है एजेक्स का इस्तेमाल करते हुए प्रत्येक 5 सेकंड के बाद एक यूआरएल का चुनाव करें यूआरएल एक जेसन प्रतिक्रिया देता है नीचे वह कोड है जो मैंने $ (दस्तावेज़) के अंदर लिखा था। ऐसा करने के लिए पहले से ही। लेकिन, setTimeout () फ़ंक्शन कार्य नहीं करता है प्रतिक्रिया प्राप्त होने के तुरंत बाद startPoll () फ़ंक्शन को कहा जाता है। मैं पुनरारंभ समारोह को कॉल करने से पहले प्रतिक्रिया प्राप्त होने के बाद 5 सेकंड के लिए रोकना चाहता हूं। इसे ठीक करने का कोई भी तरीका? 

  $ (दस्तावेज़) .ready (फ़ंक्शन () {var startPoll = function () {$ .post ('& lt; url & gt;', {}, onPollRequestComplete, 'जेसन');} var onPollRequestComplete = function (प्रतिक्रिया) {responseObject = eval (प्रतिक्रिया); यदि (responseObject.success) {// यहाँ कुछ करो} setTimeout (startPoll (), 5000); / * बाद में अगले मतदान अनुरोध करें 5 सेकंड * /} startPoll ();});

धन्यवाद

यह आपकी समस्या है:

<प्री> सेटटाइमआउट (स्टार्टपॉल ()), 5000);

आप 5 सेकंड के बाद तुरंत नहीं, तुरंत startPoll कॉल कर रहे हैं इसके बजाय, आपको फ़ंक्शन संदर्भ में पास होना चाहिए, जैसे: 

  setTimeout (startPoll, 5000);

यदि आप मतदान को हर 5 सेकंड में आग लगाते हैं, भले ही पिछली चुनाव काम न करें (एक सर्वर त्रुटि आई थी), आपको इसके बजाय setInterval का उपयोग करना चाहिए। यदि आप त्रुटियों के मामले में मतदान रोकना चाहते हैं तो आपके पास अब अच्छा कोड है।

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
