Javascript and XBasic Help Please

[mvaughn]

Dialog has a button that I want clicked from the embedded grid.

Ajax Callback from grid:

function test as c (e as p)
   dim js as C
   js = js + "{grid.Object}.getParentObject().buttonClick('BTNPRICE');" 
   test = a5_run_javascript(js) 
end function

What is the correct way of doing this?

Hi Michael

Here is the simplest example of doing it from an ajax callback:
function test as c (e as p)
test = "{grid.Object}.getParentObject().buttonClick('BTNPRICE');"
end function

Re: Javascript and XBasic Help Please

Actually, you would just put this in the inline javascript of the grid event:

{grid.Object}.getParentObject().buttonClick('BTNPRICE');

Otherwise you're making a trip to the server just to execute client-side Javascript.

That said, I bet it's not working as is, and that's why you posted it. I'm shooting from the hip here, but I think it'd be more like this:

var myDialog = {grid.Object}.getParentObject();
myDialog.buttonClick('BTNPRICE');

Re: Javascript and XBasic Help Please

Thank you Chris, I was trying to do it from an xbasic function where I have trouble figuring out how to use e.javascript correctly.
Is e.javascript only to be used as a function return or can it be used as is?

Function return:

function test as c (e as p)
   .....
   .....
   test = e.javascript = (blah)
end function

As-Is:

function test as c (e as p)
   .....
   myvar = e.javascript = (blah)
   .....
end function

I'd really like to master this because I can do much with it.

Shooting from the hip again, but I think the Dialog AfterValidate (and similar) functions use e.javascript. Xbasic functions are just a string value for the function, e.g.

myFunction as C (e as p)
'xBasic
today = date_format(date(),"MM/dd/yy")
myFunction = "alert('Today is " + today + ".');{grid.Object}.refresh();"

The grid AfterSubmit etc have an example in the comments with aa. and some kind of array(? not in front of me right now).

I am never going to defend the documentation in Alpha, but a lot of the basics are right there in the function prototypes for you to use. Or the links around the function, etc. That's how I remember this stuff, too.

Hi Michael

In your first example you were using your own xbasic function. In the case of your own function, you basically just set the return value of the function to be the javascript you want executed. So in my first reply posted above, you used the function name test, so we set test to be the javascript we want executed:

function test as c (e as p)
test = "{grid.Object}.getParentObject().buttonClick('BTNPRICE');"
end function

In the predefined Alpha server-side events we need to return the javascript we want executed a bit differently, so to do that, we use e.javascript. Take for example the afterDialogValidate event, one way to execute some javascript after that event completes would be populate it into e.javascript. For example:
e.javascript = "alert('test');"

Re: Javascript and XBasic Help Please

Thanks Mike, that cleared things up for me.

If I understand this correctly,
e.javascript can be used

1) As a function return in an xbasic function
2) As a command in Server-Side

Let's assume that I want to use it as a command inside of an xbasic function, instead of as a return.
I'm guessing that I would need to call an outside function as in...

function main as c (e as p)
   .....
   test(e)
   .....
end function

function test as c (e as p)
   .....
   .....
   test = "{grid.Object}.getParentObject().buttonClick('BTNPRICE');" 
end function

Re: Javascript and XBasic Help Please

I'm just making sure we are clear, don't use e.javascript if you are using your own xbasic function. You just return your javascript into the function name.

I think I can see what you are trying to achieve now. You want javascript to execute during your xbasic function (rather than at the end) - is that correct? If it is, this probably wouldn't be a good idea, because it wouldn't happen in the order you would be expecting. It is really only intended to have javascript execute at the end of an Xbasic function.

Re: Javascript and XBasic Help Please

You were correct, I was hoping to find a way to run javascript from within xbasic because I can keep all of my code together instead of here, there and everywhere.

To summarize:
e.javascript can be used

1) As a function return in an xbasic function
2) As a command in Server-Side

Re: Javascript and XBasic Help Please

I am having trouble with the same/similar issue.
I have a button that lets the user upload a file. In the Server-side Events: After Upload, I have it call an xbasic function (xb_save_file_to_ticket_upload_table) to put the data from the uploaded file into the appropriate table. At the end of the xbasic function, I am trying to call a javascript function to do some screen stuff.
I have tried:
e.javascript = "js_load_tickets();" -- this gave me an error message -- js_load_tickets is undefined (I know it is there)

e.javascript = "{dialog.object}.runAction('run_js_load_tickets');" (after creating an action script called run_js_load_tickets that calls the js_load_tickets function) -- this gave me an error messag -- DLG1_DlgObj is undefined

xb_save_file_to_ticket_upload_table = "js_load_tickets();" --- this does not give me an error, but it does not call the js_load_tickets function either.

At this point, the js_load_tickets only contains an alert to let my know I 'arrived'

function js_load_tickets(){
alert('in js_load_tickets');
}

what am I doing wrong?

Re: Javascript and XBasic Help Please

Anita, you can follow this example on how to call javascript from xbasic:

XBASIC:

function my_xbasic as c (e as p)
   ...
   your code
   ...
   my_xbasic = "closeme();"
end function

JAVASCRIPT:

function closeme(){
   {dialog.Object}.resetForm(false); 
   {dialog.Object}.closeContainerWindow(this);
}

OR COMBINING THE TWO:

function my_xbasic as c (e as p)
   ...
   your code
   ...
   my_xbasic = "{dialog.Object}.resetForm(false);{dialog.Object}.closeContainerWindow(this);"
end function

I hope that helps :)

Re: Javascript and XBasic Help Please

Michael,

If you looked at the examples I gave, I tried that approach:

function xb_save_file_to_ticket_upload_table as v (e as p)



xb_save_file_to_ticket_upload_table = "js_load_tickets();"

function js_load_tickets(){
alert('in js_load_tickets');
}

Re: Javascript and XBasic Help Please

Michael,

If you looked at the examples I gave, I tried that approach:

XBASIC FUNCTION:
function xb_save_file_to_ticket_upload_table as v (e as p)

' code
'more code


xb_save_file_to_ticket_upload_table = "js_load_tickets();"

end function

JAVASCRIPT FUNCTION:
function js_load_tickets(){
alert('in js_load_tickets');
}

It does not give an error, but it also does not ppup the alert message.

Re: Javascript and XBasic Help Please

Anita, your error is in the function declaration. Xbasic requires this exact syntax:
function function_name as C (e as p)

Change the "v" to a "c" and you'll be all set.
