Javascript bookmarklet to take info from one page and submit it to form on another page -

-

Now when I came to know that I can not write Javascript in a page to enter form data on any other external page , D likes to do this with a browser-based bookmarklet

I can access the data on my original page with this bookmarklet code snippet: 

  Javascript: var% 20thecode = document.myForm.myTextArea.value;

If I manually open external web-based forms in the browser, this code changes into the text box: 

  javascript: zero (document) ExternalForm.externalTextArea.value = "Hello World");

and this bookmarklet will open a new browser window with external form: 

  javascript: newWindow = window.open ("http: // www ( Newlindro.com), "newwindow"), if (window.focus) {void (newWindow.focus ())}}

However, when I put these snippets together Trying to open an external window in a new window and to change the data, a single bookmarklet, I can not access any element from the new window, for example, in this new window Text field does not work to check the current values ​​

  javascript: var% 20newWindow = window.open ("http: //www.url.com," "new window" ); If (window.focus) {zero (newWindow.focus ());} window.alert (newWindow.document.externalForm.externalTextArea.value);

Once I'm new I use the bookmarklet code to open windows as a new window, so I do not think it is capable of reaching the elements within that new window. Any suggestions I'm missing? Thank you.

This is the reason that bookmarklet runs within the current web page's sandbox (environment). Since you do not have permission to access another page that does not have the same protocol, domain name and port, you are not able to access the document to new window When protocols, domains and ports do not match. BTW, the same is true for reaching iframe s on a page.

As you are talking about "external form", I think that you do not live on the domain. Other examples will have to retrieve or manipulate data on the current page (at that time) and there will be no error.

Update: About Delicious (et al) Bookmarklet: Its code really reads: 

  (function () {f} = 'Http://delicious.com/save?url=' + encodeurIComponent (window. Location.href) + '& amp; title =' + encodeurIComponent (document.title) + '& amp; v = 5 & amp; ;; a = function (if (! Window.open (f + 'noui = 1 & jump = Doclose', 'deliciousuiv5', 'location = yes, links = no, scrollbars = no, toolbar = no, width = 550, height = 550 ')) location.href = f +' jump = yes'}; if (/f / Firefox / .test (navigator.userAgent)) {setTimeout (a, 0)} else {a ()}}) ()

So, yes, the parameters are transferred using only one Request request.

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
