Reflection in Rebol: Is it possible to know the script/object/function that is executing? -

-

यदि आर 3 में यह संभव नहीं है?

हाँ और नहीं।

तकनीकी तौर पर, नहीं ..... फ़ंक्शंस के नाम नहीं हैं, वे अनाम हैं एक ही समारोह एक से अधिक शब्द को सौंपा जा सकता है, इसलिए वास्तविक नाम समस्याग्रस्त है। 

  do func [] [प्रिंट "हे विश्व"] ;; इस फ़ंक्शन का स्पष्ट रूप से सभी नामों पर कोई नाम नहीं है: फ़्ंटक [] [प्रिंट "यो विश्व"] ;; यहां तीन नामों के साथ एक समारोह है f2:: f1 f3:: f2

कुछ मामलों में अभ्यास में, हां .... आप वर्तमान नाम (यदि कोई है) को पकड़ कर सकते हैं एक चाल: एक त्रुटि को कैप्चर करें, और त्रुटि ऑब्जेक्ट में स्टैक पर नाम होता है: 

  f3: func [/ स्थानीय ईओ] [ईओ: निहृ € ा प्रयास करें [0/0] प्रिंट ["नाम है "ईओ / कहां]] एफ 4:: एफ 3   <पी> इसे आज़माएं:  
  & gt; & gt; एफ 3 नाम एफ 3 है & gt; & gt; एफ 4 नाम एफ 4 है  
 
 यहां एक व्यापक चर्चा है:

asp.net - Javascript/DOM Why is does my form not support submit()? -

-
This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

-
I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
