VL-Web: can't return from a widget to a web page

[Rieko Saitoh]

Hi,

I created the following application
・Write HTML code in the HTML container and display the list. Place a check box in a specific column of the list.
・Calling widget when check box is clicked.

But, clicking on the check box causes an error. The widget generates an error and can not return to the calling web page.
I will attach this web page and widget.

If you are experienced with widgets, could you check the definition of the widget? Could you point out where the problem is?

Thank you.

I can get this to work, but I don't know much about jQuery:

PROTOTYPE.onRealizeControl = function( parentDiv )
{
var pThis = this;

// Provide the code to visualize the widget, FOR EXAMPLE...
parentDiv.appendChild( document.createTextNode( this.Caption ) );

$('.HR_MonthlyRoster tbody tr input:checkbox').on('click', function() {
pThis.firecheckboxClicked();
});

}

Hi Mark,

Thank you for your reply.
I changed the widget code as below. However, unfortunately the console log is not written. Also, processing can not be returned to VL-Web. Is my code incorrect?
---------------------------
code:
---------------------------
PROTOTYPE.onRealizeControl = function( parentDiv )
{
var pThis = this;

parentDiv.appendChild( document.createTextNode( this.Caption ) );

$('.HR_MonthlyRoster tbody tr input:checkbox').on('click', function() {
console.log("Check box is clicked1");
pThis.firecheckboxClicked();
});

}
---------------------------

Sorry to bother you again.
Thank you.

You are using jQuery to fire the click event, which seems to be where the root of the problem is.
As I mentioned, unfortunately I don't know anything about using JQuery.

I do notice that in your web page your widget does not have a Parent()? Try

Define_Com Class(#LJ12003) Name(#LJ12003) Displayposition(2) Parent(#COM_OWNER) Tabposition(2)

Hi Mark,

As you advised, I did not specify the widget's Parent on the web page. By specifying Parent, the web page can detect the widget's signal.
Now my goal can be achieved. Thank you so much for your advice!!
