Hi,
Is there a function to call a javascript program from Maintain. For example, to call Maintain from javascript use IWCTrigger. I need to go in the opposite direction.
Thank you,
Nick

Where do you want to call from ?

Here is an interesting way to make a piece of dynamic javascript in Maintain.

Step 1: Create an empty javascript file.
Step 2: Add the javascript file to the form, not as a link.
Step 3: scriptfilename.lines(scriptfilename.lines.FocCount + 1) = 'javascript line;' ;

In you maintain code add step 3 before showing the form, then the scrip line will be executed when the HTML form in loaded.

Hi Waz,
Thanks for the quick response.
I want to send emails to selected reciepients with a custom user entered message for each receipient. I have a routine, provided by Mark, that sends emails launched via the onclick event.

I would like to use this javascript code to send emails to selected receipients. Since each receipient will have a customized message, I have to send multiple emails. The process that evaluates if an email will be sent is in Maintain.

High level logic is:
IF EMAILIND EQ 'Y' THEN "CALL EMAIL Javascript";

Hope this helps.

Thank you,
Nick

Have a look at the maintain below, it may show you what I am suggesting.

jscall.mnt

MAINTAIN

Case Top
Winform Show Form1; 
EndCase
END

Hi Waz,
Thanks again!

Calling the javascript function from a button is functioning properly but I need to call the javascript function from the Maintain procedure. For example,

jscall.mnt

MAINTAIN
$$Declarations
Case Top
Winform Show Form1;
EndCase
Case email
compute to/a100='nick@njginc.com';
compute from/a100='nick@njginc.com';
compute subject/a100='hello';
compute body/a100='this is a test';
call jscall
endcase
END


Currently, the form has a button where the js code is as follows:

webpage = "http://xxx:8080/approot/xxx/test4.jsp";
getTo = document.getElementById("To_Edit").value;
getFrom = document.getElementById("From_Edit").value;
getSubj = document.getElementById("Subject_Edit").value;
getBody = document.getElementById("Body_Edit").value;
url = webpage + "?getTo=" + getTo + "&getFrom=" + getFrom + "&getSubj=" + getSubj + "&getBody=" + getBody;
window.open(url,"emailwin");


I need to perform the same activity in Maintain code or call a js function from Maintain that has the code above.

Thank you,
Nick

Nick,

If the only function of the maintain is to call a js functions, then you might be better off writing a html solution for your problem.
Calling js from maintain can't be done as is. You'll have to do this through some action within maintain that is linked to a javascript function. It can be a js linked to a button, which gets executed upon clicking the button, or linked to the form, which gets executed when the form gets loaded. If you don't have forms, then sorry, no javascript functionality.
In your case it seems you have a form. Then I'd try to put all the data you need to send out on the form (hidden or not) and have a javascript program read all this data and process it. Link the javascript to the form in such a way that it gets executed when the form loads.

Hope this helps...

Hi GamP and Waz,
Thanks for your help. So far, with assistance from you and my friends at IBI, I've been able get it to work by using an HTML object as follows:
1. Populate a stack with the javascript statements.
2. Use the stack as the data source for the HTML object.
3. Trigger execution of the HTML object by a form refresh.

This solution assumes that the form will remain open and the HTML object will be triggered by a form refresh. Since the objective is to send emails to selected individuals each with a customized message, this works but the user will have to click a second button to exit this form. This is no biggie, I think.

Thank you,
Nick

Nick, what I gave you does call a js function from maintain. the example has the button to call a maintain case. This case then populates the js code embedded in the winform with the js call.

If I understand you correctly this will work for you.

quote:

the user will have to click a second button to exit this form

Couldn't you, after the js is done, code a window.close() and a IWCTrigger("WINEXIT") to close the form and the maintain?

Hi Waz and GamP,

The original concept was a user would set the email indicator for that person to 'Yes', state a customized message in a comments field and the email would be sent upon leaving that person's record. Since there are a number of ways to leave the person's record and the approver may exit after entering a person's record, I choose to trigger the email creation and distribution process from a button. So, Waz your technique will work and I will compare solutions later today. GamP, I will integrate your suggestions to close the page and post a message.

Thank you both for assisting me as I am a seasoned FOCUS programmer but relatively new to WebFOCUS and javascript.
