Get variable from browser?

[stu]

Hi,

I been trying to get a variable (?) from a javascript based web application that is used for booking seats. (http://jsc.mm-lamp.com/)
Like clicking on a seat and somehow be able to retrieve the "row_column" (following the example scheme) so I can store that in a database from Neobook. My lack of experience using javascript and Neobook is not helping...

Any idea on how to manage such task?

Regards.

Stu,

Here is a function I created in NB by adapting a Javascript:

Take a look at it, especially at the last few lines. When using javascript functions, you define the function and then call it. You submit data via the NB function mechanism using variables defined with this type of name [%1] .

Try doing something and then report where you reach any roadblocks.

Well, what I have done is add window.external.nbSetVar( '[ClickedSeat]', this.settings.label ); to the original code in the example (http://jsc.mm-lamp.com/) and now when I click on a seat it captures the number, so its good, my current problem has mutated into: how can I do something after I click on a seat, so for example if I want to select multiple seats I can stored them comma separated (or whatever) in a variable, that would be the last part of my afternoon project =)

And actually a bit of a background...

Lets say I'm looking into updating a database right?, so I want to book seats 12,13 20 to the same person, I click on them and then then I pass a variable holding 12,13,20 to Neobook so I can carry on working with the data.

Cheers.

Well, if you poke these values into the database you are using, you should be able to have a subroutine run upon any change in the table (this is set in the place where you use dbpopentable ). This is how you can notify NB that a change has been made and it needs to act upon it.

The best way to get a variable from an external web page?

Let's say you want to get a client name from a web page in WebBrowser1 and save it as a NB variable [Name]. You may want to simply copy a browser variable to a NB variable. But that does not always work very well. You must first hard wire the client name in your web page by putting it into a text field, in this case "FirstName," which could be within a form, in this case "Client."

Here is the web page javascript (this action uses the name="Client" not id="Client" javascript tags, etc.)

Code: Select all

<form name="Client"><input type="text" name="FirstName" value="Bob"></form>

or

Code: Select all

<form name="Client"><input type="hidden" name="FirstName" value="Bob"></form>

And here is the NB action. Also note below that a : sign must separate the form name from the field:

Code: Select all

BrowserGetElement "WebBrowser1" "Client:FirstName" "[Name]"

The value for the NB variable [Name] will be "Bob."

So, if you do something like this with the "seats" of your website (instead of the name example), you can add them all to a final list in Neobook, and then assign them to whoever wants to reserve those seats.

You can just keep adding your seat variable, in this case [Seats}, to a local file or listbox with these actions:

FileWrite "" "Append" "[Seats]"
ListBoxAddItem "" "0" "[Seats]"

You might also want to hide or taint out the selected seats from your website to indicate which seats have been taken.

So if it is an EXTERNAL (not in NB) web page, how do you determine the name of the browser being searched? Title? ProcessID? AppID?

BrowserGetElement "WebBrowser1" "Client:FirstName" "[Name]"

This is the browser: "WebBrowser1"

it could be any name you give the browser object when you create it (not the current url)

If you mean an external popup IE browser window, you can get its name with the hpwSendKeys plugin.
Assuming it will be the top window once it opens, hpw will find it

If it is from your website you should already know the window title and hpw can perform various actions on it... If it is from your website, instead of opening it in a popup window, it is easier to send the url to WebBrowser2 (for example) where you can have more control to copy, parse or modify the source code with NB actions...

BrowserExport "WebBrowser2" "[sourcecode]"

WebBrowser2 need not be seen by the user (sent to back) and closed when finished...
By "close" I mean empty it
BrowserGoTo "WebBrowser2" "about:blank"
and then make it invisible or disabled
