setValue of a checkbox to blank

[hangbill]

Hi
This code tries to set the value/s inside checkboxes to blank. whatMeds is the checkbox.
The code runs (no errors) but the values in the checkbox are not deleted. It works with a dropdown, but seems not with checkbox.
How do I get this to work?
Thank you

// delete value in WhatMedication if MedsWhenLast > 12 months. Place in OnChange event of MedsWhenLast
var whatMeds = {dialog.object}.getValue('WhatMedication');
var medsWhenLast = {dialog.object}.getValue('MedsWhenLast');

if (('>12-24 months' == medsWhenLast) || ('>24 months' == medsWhenLast)){
	{dialog.Object}.setValue('whatMeds', '');	
}

Re: setValue of a checkbox to blank

var data = {dialog.Object}.getValue('MEDS_WHEN');
if (data == '12-24 months' || data == '>24 months') {
{dialog.Object}.setValue('WHAT_MEDS','');
}

this works for me, I don't use reverse checking like the pros do.
I am assuming the meds_when is a dropdownbox.

Yes MEDS_WHEN is a dropdownbox.
Must be doing something wrong but no script error messgs and the ticks (single or multiple values) are not deleted.
What is reverse checking?
Thanks Gandhi.

Re: setValue of a checkbox to blank

ok, got it working...
Removed the var statement whatMeds and referenced the WhatMedication field directly, like this

// delete value in WhatMedication if MedsWhenLast > 12 months. Place in onChange event of MedsWhenLast

var medsWhenLast = {dialog.object}.getValue('MedsWhenLast');
if (('>12-24 months' == medsWhenLast) || ('>24 months' == medsWhenLast)){
	{dialog.Object}.setValue('WhatMedication', '');	
}

Wonder why it did not work with the variable.
Thanks for the help.

vs

if ('12-24 months' == data || '>24 months' == data)

the second one, probably better ( you use that one) but I can't think straight like that. I need more time to learn that.

{dialog.Object}.setValue('WhatMedication', '');

I am under the impression WhatMedication needs to be in caps like WHATMEDICATION.

Wonder why it did not work with the variable.

you are setting value to the dialog object, while variable gets its value it will not operate on the object as far as I know.

Re: setValue of a checkbox to blank

Agree it does feel strange. In another post TheSmitchell suggested put the value first so that if there is a problem you get an error instead of a silent failure.

The field name in the dialog is WhatMedication and it seems to work (camelcase, not all caps).
What I find strange is that when I assign the variable name whatMeds to WhatMedication it does not work. Seems that setValue needs the actual field name, not an assigned variable with a different name. Seems it works if you reference the field name directly, or if you use a variable it must be the same name as the field name (caps etc dont matter as long as the name is the same). But then why use a variable, just set it directly.

Re: setValue of a checkbox to blank

The one reason to use variable, I think, is to go get the value from the dialog once and manipulate with it for the next few times and then get back to dialog to set a value.
On the other hand if you reference the dialog object and property in the following many calculation javascript has to go back to the dialog all the time and get the information.
May be repeated calls to dialog might annoy it and make it unresponsive. You think?

Re: setValue of a checkbox to blank

Yes it probably does make sense to use the variable. But it is strange that it seems to work only if the variable name is the same as the field name. I will watch out for this when I do more dialogs. Thanks for the help today, appreciate it...
