Show/hide labels/text boxes with a checkbox

[Hamberg]

Warning I know just enough to screw things up!

Looking to hide 3 fields based on the condition (checked or unchecked) of a checkbox.

Here are the fields:

• cb_homeage (checkbox)
• tb_yearbuilt (static label)
• tb_homeyear (dynamic, inputs for the year it was built)
• tb_homeage (calculated based on today's date - tb_homeyear)

If cb_homeage is checked, the three texboxes (tb_...) would be hidden

Here is what I have that is absolutely not working.

cb_homeage/Actions/Mouse Up/run javascript 

var fieldHide = event.target.isBoxChecked(0)?display.visable:display.hidden;

this.getField("tb_yearbuilt").display = fieldHide;
this.getField("tb_homeyear").display = fieldHide;
this.getField("tb_homeage").display = fieldHide;

One thing I am not sure about it the (and I'm sure I'm using the wrong terminology) checkbox identifier - so ...isBoxChecked(0) - not sure it's 0 (there are +/- 100 checkboxed and radio buttons)

The zero is for the first "widget" of the field, meaning the first in a series of check boxes that are named identically.  The widget numbers are in the order the fields were created starting with zero.  If this check box is the only one, then the zero would be correct to identify this check box.  However, your error is that you mispelled visible.

And that was a copy and paste :O/!!

How do I find the actual "ID" number for that check box?? There are 35+ check and radio button on this form page

In Prepare Form mode click the check-box you're interested it and it will be selected in the Fields list on the right. The number after "#" in that list is its index number in the group (note the numbers start from 0, not 1):

@try67 - unfortunately I rename these as I'm going along? 

Is there a scripting way to find it?

[PDF Automation Station]

If there's no # plus number in the fields panel, there is only one widget, so you would use the zero as you did originally.

[try67]

Yes. Look at the page property of the field. If it's a number there's only one copy of it; If it's an array, there are multiple copies.

Sorry, still confused (not uncommon!). This is a 10 page form with 50+ checkboxes and 100+ radio buttons.

This page (page 1) has 2 checkboxes. I tried var fieldHide = event.target.isBoxChecked(0) & var fieldHide = event.target.isBoxChecked(1) - neither work.

Sure I'm missing something simple!?

Side note - here is the error that is being thrown: 

ReferenceError: cb_homeage is not defined

1:AcroForm:cb_homeage:Annot1:MouseUp:Action1

[Hamberg]

Sorry, I was trying to call the check box by name in the error above

here is the error with isBox Checked(0):

TypeError: this.getField(...) is null
3:AcroForm:cb_homeage:Annot1:MouseUp:Action1

[try67]

Your field is called "cb_homeage", not "cb_homepage"... Hence the error message you're getting.

[Hamberg]

@try67 I am not calling "cb_homepage" anywhere - what are you seeing that I'm not??

[try67]

From the error message you posted... But you will need to post the full code (and/or the file) for further help with this.

Here is the whole document. Just did the page layouts and am trying to get page 1 figured out before fixing naming convenetions and such. Thanks in advance for the insight/help!

The error is because cb_homeage is not defined (when there's no quotes around it it's a variable that hasn't been defined).  It should be replaced with 0 to determine whether the box is checked in the Mouse Up action.  You are also calling field names that do not exist in the rest of the script so there will more errors.  However, since the checkbox "cb_homeage" has no other copies it's a lot easier to use the following script:

var fieldHide=event.target.value=="Off"?display.hidden:display.visible;

//set display of your fields to fieldHide, example:

this.getField("tb_homeage").display = fieldHide;

Thank you! Something I didn't realize.. Once Javascript his an error the script stops? Is there anything like an: onerror.resume?

[try67]

- Yes.

- No, unless you catch the error in a try-catch clause, which you shouldn't really do. You should solve it.

[PDF Automation Station]

Correct.  All the scripts stop when an error is triggered.  That's why you'll see "did you check the console for errors" a lot in the repsonses in this forum.  When someone uploads a form and says "it doesn't work" the first thing I do is clear the console.   Next I trigger a calculation, then I check the console.  It's a good way to trouble shoot.  As @try67 said, you can use try/catch, but all that will do is skip the error and you won't be able to find it.
