javascript - How do I access form element values using ruby without submitting the form? -

-

OK, I still have a comprehensive Ruby app behind Ruby running Ruby, this app needs input , But when I update the text box, I do not want to refresh the page. What do I mean:

I have a form that has two text boxes, one is called "starttime" and one is called "endtime" I pressed a button in some way When the value of these text boxes (which are typed in a user) needs to be found in Ruby. Is there anything equivalent to the JavaScript documentation? Format.starttime.value command but for Ruby? Or is there any way to submit form data, retrieve it, but do not refresh the page like using AJAX? I know that Ajax is used to manipulate DOM dynamically without refreshing the page, but I really need to retrieve the data. Any help would be greatly appreciated, I can not find it anywhere.

You can do it very easily. Give the start time and end time form elements a different ID (I use start date and endDate below) and you can easily retrieve them, then You can send data in a Rail operation and process them in the background and if necessary, update the DOM with any relevant data when you click on a button (ID SendDateValues ​​ Confirms.)

something like this (not tested) 

  & lt; Script type = "text / javascript" & gt; // $ ("# SendDateValues") (function () {$ .ajax ({url: '/ some controller / process data / data', data: 'startDate =' + $ ("# startdate") .val () + "& EndDate =" + $ ("# end date"). Val (), success: function (html) {// do something with result}, type: 'post'});}); // $]

Run with the result ... Use firebug or check anything similar to what happens. Check your Rail Event Log What data did your action occur?

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).
