Client side scripting

Post by 247Oversight » Tue Jul 05, 2016 8:27 pm

I have a project for our service tech. I need to access the GPS location from smart phones and tablets.
What is the process to set up client side scripting with Java or HTML5 ?
Thanks for your help.

Hello,

you can add own scripts according to this example.
1. locate and open
www\software\html5\settings.js

2. look for

Code: Select all

W.customerScripts = { 0: "../custom1.js" }; //example
                         // { 0: "../custom1.js", 1: "../custom2.js" };  // "../*" is web root
                         //Important notice: the third part JavaScripts and any issues/incompatibilities caused by it's usage are not covered by support and any help on it will be discarded!


4. save settings.js

5. save your customer script as example under www\custom1.js

Now you are free to use your own scripts...
But that step will make no sense, if you can not communicate with session, therefore...

Are you conform with AutoIt? If not, well, you have to learn it, since following example is in Autoit.
It is easy to compile to exe with AutoIt (you will have to google for it)

Code: Select all

Save this snippet to server.au3 file, compile to exe, and execute inside session.
That was listening server example, once you start this server.exe (compiled au3) it will listen to messages from channel you send from browser.

Take attention at this part (I have commented it in script to disable)

Code: Select all

;***
    ;//$data = $data & "   alert('Listening mode\r\nAfter clicking OK the message ""' + userMessage + '"" \r\nwill be sent back to customer channel:\r\n ' + channelCustomName); " & @CRLF
    ;//$data = $data & "   W.sendChannelCustom('" & $ChannelCustomName & "', userMessage); " & @CRLF
;***
That is pure JavaScript part, that gets executed inside browser
In this example it gets first initial data, and than listens for incoming messages, after first initialisation you could add inside your www\custom1.js something like

Code: Select all

window.sendMyMessageBack = function(do_what) {
  ///do what ever you want here
  ///if(do_what == 1) { } etc..
  //
  var messageBack = "what ever you did";
  if("channelCustomName" in window &&  window.channelCustomName.length > 0) {
    W.sendChannelCustom(window.channelCustomName, messageBack);
  }
};
So to force the browser to send messages from inside session, make it also event driven, what I assume, you want to do here is next AutoIt snippet, almost equal to
server part but Global $ExitOnFirstMessage = True; also once it sends message, it exits immediatelly, also client version only.
Also as example save that snippet to client.au3 and compile to client.exe, and after you are sure, that server.exe runs, start client.exe.

Code: Select all

;////code client.au3 start
#NoTrayIcon
#include <WindowsConstants.au3>

Global $ExitOnFirstMessage = True;
       ;//False means, the process will run permanently in listening mode and may receive messages

       ;//never send persistent _sendPersistentMessage when $ExitOnFirstMessage = True

Technically you could completely avoid usage www\software\html5\settings.js -> W.customerScripts
and evaluate your functions on first server.exe(.au3) start, as example

Code: Select all

;//server.au3 start
****
    $data = $data & "   window.ChannelCustomName = channelCustomName; " & @CRLF
    $data = $data & "   window.sendMyMessageBack = function(do_what) { " & @CRLF
    $data = $data & "     var messageBack = ""what ever you did""; " & @CRLF
    $data = $data & "     if(""channelCustomName"" in window &&  window.channelCustomName.length > 0) { " & @CRLF
    $data = $data & "       W.sendChannelCustom(window.channelCustomName, messageBack); " & @CRLF
    $data = $data & "     } " & @CRLF
    $data = $data & "   }; " & @CRLF
****
;//server.au3 end
But that would make it hard to debug for you.
(remember under au3 some chars are escaped differently than by JavaScript, as example for Autoit for escaping " you must type it twice "")

PS: but unfortuantelly I can not give you aid on your code, because it is not covered by support. Any browser related issues are fully yours.

Hello,

fixed some spellings errors and made the server.au3/client.au3 custom example script usage ready to use, also wished function gets evaled once from server.au3 instead from www\custom1.js
And client.au3 plays the role of event driver.
However you may pack as example the call of function window.sendMyMessageBack into setInterval and poll for changes of gps location, and only than send message back to server, or make it event driven on side of browser. So you could avoid usage of client.au3 too.

Returning from vacation. Thank you for all your help. Take a couple of days to get back on track in the office and then I will start work on this project. Once again thank you for your time and help on this request.

Have a Great Week,

Thanks for the clarification! Got it working.
I'm gonna learn some tricks, the basic ones. I need to know all the main concepts. They can be used at the table. But they won't help me with that roulette.

The client-side environment used to run scripts is usually a browser. The processing takes place on the end users computer. The source code is transferred from the web server to the users computer over the internet and run directly in the browser. The scripting language needs to be enabled on the client computer.

Re: Client side scripting

A client-side dynamic web page processes the web page using HTML scripting running in the browser as it loads. JavaScript and other scripting languages determine the way the HTML in the received page is parsed into the Document Object Model, or DOM, that represents the loaded web page. The same client-side techniques can then dynamically update or change the DOM in the same way.
