javascript - Why does appending a <script> to a dynamically created <iframe> seem to run the script in the parent page? -

-

मैं एक & lt; iframe & gt; जावास्क्रिप्ट का उपयोग कर, फिर एक & lt; स्क्रिप्ट & gt; तत्व & lt; iframe & gt; के लिए तत्व जिसे मैं & lt; iframe & gt; d दस्तावेज़ के संदर्भ में चलाना चाहता हूं।

दुर्भाग्यवश, ऐसा लगता है कि मैं कुछ गलत कर रहा हूं - मेरा जावास्क्रिप्ट सफलतापूर्वक निष्पादित होता है, लेकिन & lt; स्क्रिप्ट & gt; पैरेंट पेज है, & lt; iframe & gt; d दस्तावेज़ नहीं है जब भी ब्राउज़र iframe_test.js का अनुरोध करता है, तो मुझे फ़ायरबग के "नेट" टैब में 301 त्रुटि भी मिलती है, हालांकि यह फिर से अनुरोध करता है (सुनिश्चित क्यों नहीं?) सफलतापूर्वक।

यह मैं जिस कोड का उपयोग कर रहा हूं (पर लाइव डेमो):

iframe_test.html 

  & lt;! DOCTYPE html public "- // W3C // डीटीटी एक्सएचटीएमएल 1.0 सशक्त // एन "" http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> & Lt; html xmlns = "http://www.w3.org/1999/xhtml" xml: lang = "en" lang = "en" & gt; & Lt; शीर्ष & gt; & Lt; मेटा http-equiv = "सामग्री-प्रकार" सामग्री = "पाठ / html; वर्णसेट = यूटीएफ -8" / & gt; & Lt; title & gt; & amp; lt; आइफ्रेम & amp; gt; परीक्षण & lt; / title & gt; & Lt; / head & gt; & LT; बॉडी & gt; & Lt; div id = "बाल्टी" & gt; & lt; / div & gt; & Lt; स्क्रिप्ट प्रकार = "टेक्स्ट / जावास्क्रिप्ट" src = "http://jqueryjs.googlecode.com/files/jquery-1.3.2.min.js" & gt; & lt; / स्क्रिप्ट & gt; & Lt; स्क्रिप्ट प्रकार = "टेक्स्ट / जावास्क्रिप्ट" & gt; $ (दस्तावेज़) .ready (फ़ंक्शन () {$ ('# बाल्टी')। ऐप ('& lt; iframe id = "test" & gt; & lt; / iframe & gt;'); setTimeout (फ़ंक्शन () {var iframe_body = $ ('#test')। सामग्री ()। ('शरीर') खोज; iframe_body.append ('& lt; scr' + 'ipt प्रकार = "पाठ / जावास्क्रिप्ट" src = "http://onespot.wsj.com/ स्थिर / iframe_test.js "& gt; & lt; / scr '+' ipt & gt; ');}, 100);}); & Lt; / स्क्रिप्ट & gt; & Lt; / body & gt; & Lt; / html & gt;

iframe_test.js 

  $ (फ़ंक्शन () {var test = '& lt; p & gt; यह नहीं होना चाहिए & Amp; amp; lt; iframe & gt;? & Lt; / p & gt; '$ (' body ') के अंदर हो। एपेंड (परीक्षण);});

असामान्य लगता है कि एक बात यह है कि कोड में iframe_test.js भी काम करता है; मैंने & lt; iframe & gt; में jQuery लोड नहीं किया है स्वयं, केवल मूल दस्तावेज में। यह मेरे लिए एक सुराग जैसा लगता है, लेकिन मैं समझ नहीं सकता कि इसका क्या मतलब है।

कोई भी विचार, सुझाव, आदि बहुत सराहना की जाएगी!

< Div class = "post-text" itemprop = "text">

एक ही समस्या थी, समाधान खोजने के लिए मुझे समय लगा। आपको iframe के दस्तावेज़ का उपयोग करके स्क्रिप्ट की ऑब्जेक्ट बनाने की आवश्यकता है। 

  var myIframe = document.getElementById ("myIframeId"); Var स्क्रिप्ट = myIframe.contentWindow.document.createElement ("स्क्रिप्ट"); Script.type = "text / javascript"; Script.src = src; myIframe.contentWindow.document.body.appendChild (स्क्रिप्ट);

एक आकर्षण की तरह काम करता 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 am trying to implement one for Delphi, but there are some problems with communication. Fitnesse will start my process, and give me a portmember as a command line argument. Then I should make a socket on the port number given to me, and fitness will connect to that port I am using a TCPCP server for the job: < Pre> TcpServer1.LocalPort: = ParamStr (ParamCount); TcpServer1 Active: = true; On OnEXEPT () -Event, I send the protocol version to use as specified in the protocol. Process TForm1.TcpServer1Accept (From: TOBject; ClientSocket: TCustomIpClient); Var s: ansistring; Start clientSocket.

javascript - Classic ASP "ExecuteGlobal" statement acting differently on two servers -

-
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
