Is it possible to pass a variable to Exec Display htm from IPA?

chris-mccullough

I am using the ResSum.htm display and would like to modify the GetReqDtlInfo  function so I can pass a variable I make inside of the flow to the display so that the dme call only grabs certain lines from the Req and displays only those lines. Something like:

function GetReqDtlInfo()
{
var logancall = new DMEObject(prodline, "REQLINE")
logancall.out = "JAVASCRIPT"
logancall.field ="item;description;quantity;entered-uom;unit-cost"
logancall.index = "rlnset1"
logancall.max = "250"
logancall.xida = true
logancall.select = "line-nbr=2|line-nbr=3"
logancall.key = m_Company + "=" + m_ReqNumber
logancall.func = "displayRecSum()"
DME(logancall, "REQLINE")
}

So perhaps in the flow, I create a variable called "dmeSelect" and build it dynamically based on the line numbers I need" "line-nbr=2|line-nbr=3"

So the function would actually look like:

function GetReqDtlInfo()
{
var logancall = new DMEObject(prodline, "REQLINE")
logancall.out = "JAVASCRIPT"
logancall.field ="item;description;quantity;entered-uom;unit-cost"
logancall.index = "rlnset1"
logancall.max = "250"
logancall.xida = true
logancall.select = m_dmeSelect
logancall.key = m_Company + "=" + m_ReqNumber
logancall.func = "displayRecSum()"
DME(logancall, "REQLINE")

Is this possible?

Thank you for your time!

If I am reading your request correctly you want to pass a variable from IPA Workunit through to the display,  so you can then use that variable to modify the DME call that is made by the display execute.   It's been awhile since I've played with the display exec (I now lean towards having the flow just build the html that I want the user to see) ...  but to each their own.

To achieve this,  it wouldn't be a delivered process but it should work....

STEP 1

Modify your UserAction node;   On the Display tab where you specify your recsum.htm display exec.  Where you would normally place "recsum.htm" on the File Id field.   Add a variable here so it looks like this....

var variableWithContent="data,data,data";

File Id:  recsum.htm?<!variableWithContent>

When your flow now encounters the User Action node it will up building a url that looks like this to access your display exec.
http(s)://lsfserver:port/bpm/htmlinbasket/execs/recsum.htm?data,data,data?1000|WORKTITLE|PDL


STEP 2
Modify your recsum.htm


There should be javascript that pulls the classic WU, worktitle, and the pdl from the URL already.  We just need to modify it handle our new URL style.

var prmPassed=unescape(window.location.search);
var [m_dmeSelect,prmPassed] = prmPassed.substring(1).split("?");
prmPassed = prmPassed.split("|");




EXPLANATION OF CODE IF REQUIRED

var prmPassed=unescape(window.location.search);   
**results in prmPassed=?data,data,data?1000|WORKTITLE|PDL

var [m_dmeSelect,prmPassed] = prmPassed.substring(1).split("?");  
**substring removes the first? then split on the ? into two variables
**m_dmeSelect = data,data,data
**prmPassed=1000|WORKTITLE|PDL

prmPassed = prmPassed.split("|");
**builds the regular array that is leveraged by the normal display to populate the classic wu,worktitle,pdl, etc

At any rate this would allow you to take a variable from a running flow and pass it through to the display exec.   NOTE:  If you put multiple variables in there or any special characters in that code you would want to perform a escape function on that variable from IPA before the user action node.  Looks like the javascript default uses unescape so use the escape function if there are special characters in there that cause an issue with the url.

Essentially by overriding the File Id we are hijacking the normal URL that is built programmatically so we can include some additional information.

I hope this helps
