Access Custom Attributes in JavaScript and in Transactions

Question

Hello,
I try to work with custom attributes. I've problems accessing the values in JavaScript and in transactions, but it works fine within .irpt pages.
What's the trick?
For a custom attribute called PLANT, can I write something like this in JavaScript?
var p = ;
Is there a way to access custom attributes in the Link Editor of an Action Block?
Kind Regards,
Matthias

Hi Matthias,
it is not possible to integrate that kind of MII variables in JavaScript like you discribed before.
You are right that this kind of expression is possible in the .irpt file. The reason why it is working in the .irpt
but not in the .js is, that the MII script parser is only replacing in HTML content. Everywhere you have
scripting the parser will not replace the {...} markings (since the curly brackets also show start/end of functions aso.).
Variables to JavaScript
The easiest Way to get those variables is to create hidden fields in the .irpt file that you can access via JavaScript.
For example:
<input type="hidden" id="hidden_plant" value="{PLANT}" />
This will be parsed to (e.g.)
<input type="hidden" id="hidden_plant" value="Karlsruhe/DE" />
Now you can access this value in JavaScript via:
document.getElementById( "hidden_plant" ).value;
Variables to Transactions
To parse custom variables to a transaction you first have to specify corresponding transaction variables in the
transaction itself. After saving the transaction you can map those variables to Parameters in the Xacute-Query-Editor.
Including this transaction to your webpage you can simply assign the required value to the corresponding parameter.
For example if you mapped the Plant variable of the transaction to Param.1 you can specify the information in the .irpt
like:
<applet id="trx_test" ....>
  <... />
  <param name="Param.1" value="{PLANT}" />
</applet>
Another possibility is to set the value dynamically via JavaScript if you use:
document.getElementById( "trx_test" ).getQueryObject().setParam( 1, "Karlsruhe/DE" );
Native access to user variables via the BLE is not possible (as far as I know).
I hope this is what you wanted to hear?
Best Regards
Sebastian
