If an HTML form has two <input type="submit"> buttons, how do I know which got clicked? -

-

मान लीजिए मेरे पास निम्न HTML फ़ॉर्म है: 

  & lt; form & gt; ... & lt; इनपुट प्रकार = "सबमिट करें" name = "queue" value = "Queue item" & gt; & Lt; इनपुट प्रकार = "सबमिट करें" नाम = "सबमिट करें" मान = "आइटम सबमिट करें" & gt; & Lt; / प्रपत्र & gt;

मुझे कैसे पता चलेगा कि उपयोगकर्ता किस बटन पर क्लिक किया था (जावास्क्रिप्ट का उपयोग किए बिना)?

मैंने प्रस्तुत डेटा को देखा और ऐसा लगता है कि जब "कतार मद" क्लिक किया जाता है तो "queue" = "कतार मद" को सर्वर पर भेजा जाता है और जब "आइटम सबमिट करें" क्लिक किया जाता है तो "सबमिट करें" = "आइटम सबमिट करें" सेट भेजे जाते हैं।

क्या मैं इस व्यवहार पर भरोसा कर सकता हूँ? क्या यह कहीं HTML रूपों पर मानक में प्रलेखित है? आप लोग कैसे करते हैं?

हां, आप इस पर भरोसा कर सकते हैं; यह पूरी तरह से प्रलेखित है विशिष्ट प्रासंगिक लाइनों का कहना है:

जब कोई प्रसंस्करण के लिए प्रस्तुत किया जाता है, तो कुछ नियंत्रणों में उनका नाम उनके वर्तमान मूल्य के साथ रखा जाता है और इन युग्मों को फॉर्म के साथ जमा किया जाता है। उन नियंत्रणों के लिए जिनके नाम / मान जोड़े को प्रस्तुत किया गया है उन्हें सफल नियंत्रण कहा जाता है।

और

यदि एक फ़ॉर्म में एक से अधिक सबमिट बटन हैं, तो केवल सक्रिय सबमिट बटन सफल होता है।

objective c - iPhone and it's wireless area -

-
Is this a way to find other iPhones in the category of wireless areas? So I give an example. I'm staying at the airport somewhere I have an iPhone too. I and the other iPhone owners are playing the same game. Is there any way to warn me and the other player that we are close to each other? Does this work even if we are not on the same wireless network, or there is no wireless? And if there is any way to do this, can you give me some starting point? Like a link where I can learn something like this or maybe this is probably the name of this process, because I do not know how to search about this topic in Google. Thanks in advance! Can be completed with peer-to-peer discovery and connectivity you are describing Game Kit Framework Originally I thought it works only through Bluetooth, but after watching it immediately, it seems that WiFi is also supported. Hope it helps!

unix - Listing all shared memory segments used by a process on AIX5.3+ -

-
I would like to find all the shared memory segments used by a given process I am particularly interested in detecting shmid That's why I can use it in call (shmctl). On Solaris I will just read / proc / $ PID / map to find that information (field pr_shmid) The content of that file is defined by struct prmap_t in the sys / procfs format. Ax also has a / proc / $ PID / map file. Any project is a primate, but unfortunately it has been projected in pr_shmid field. Any ideas how can I get it on AIX5.3 +? I do not particularly know about AX, but I think that ipcs command is quite standard where SysV IPC is supported, so I want to get the ipcs -m command to give the appropriate code; If you can not find a better method, then there may be an option to parse its output.
