[SOLVED] HTM executes JavaScript, then FEX, conditionally - can it be done?

Hello All,

I am new to WebFOCUS, and am currently using version 8.2.

I have an HTM file with an embedded JavaScript script that validates the user-entered data when the form is submitted.

In the Tasks & Animations, I specify JavaScript (first) and a FEX script (second).
The JavaScript ends with "return true" if the validation does not find errors in the user-entered data, or "return false" otherwise.

All seem to work well, except that the FEX is always executed.

Would it possible for us to get the FEX executed conditionally per the above?

Any insights and hints would be much appreciated.

Yes, you should be able to.

First thoughts would be to create a task for the fex execution, and a js function.

In the js function call the created task to launch the fex with the command IbComposer_execute

This assumes that you are creating the page in HTML composer.

Hello Waz,

*** This is my test js.
function execTheFex() {
alert('Launching the fex upon pressing on the OK button...');
IbComposer_execute('myFexReport');
}

*** In Tasks & Animations window...
Trigger Type: Click
Trigger Identifier: button1 (checked)

Requests/Actions: JavaScript call

Target type: JavaScript function
Function name: execTheFex()

*** When run, upon pressing on the button, I got the alert message, but nothing happens after pressing on OK there.

Any suggestions are welcome.

Thank you!

Hi Simon,

Leave your task to execute the JavaScript on form submission but remove the focexec call.

Instead, create a new task for the focexec and change the trigger type to "TBD". Remember the task id for this.

Within your JavaScript, left click and drag the task for the focexec to the point where your user entered details should result in the execution of the focexec.

This essentially does what Waz suggests above but instead of you having to type the "IbComposer_execute" code, the drag and drop does this for you.

Good luck!

Hello Tony A,

Thank you for the detailed explanation.
It works!

*** In List of: a new entry MyFex is created,
Trigger Type: TBD
Requests/Actions: External procedure/myFexReport
Target type: Window

*** Open tab, Embedded JavaScript
drag and drop MyFex (from List of) to the js page, and it does paste the text "IbComposer_triggerExecution("MyFex", 1);" there among the codes.
Rearrange the code to place the statement at the designated line in the js codes.

*** When run, upon pressing on the button, I got the alert message, then after pressing on OK there, myFexReport window appears so beautifully.

Thank you all for making my splash here such an easy one!

Cheers,
-Simon
