I have searched and tired several javascripts, but being a beginner in this area I must have forgotten something along the string. 

I have a checkbox that if selected a sentence shows up.  (I've named the checkbox and the text box, too)

Another checkbox, that if selected also a popup sentence and another exisiting filed must be required and  filled out.

It worked.   Whew I changed the scriptthis.getField("CHG").display = (event.target.value=="Yes")?display.hidden : display.visible; Thank you so much for your patience. There were more things I would like to have scripted in this form, but I must say that this simple little script has caused me a headache.  THANK YOU, again.

You'll need to be more specific about the second bit, i.e., the other checkbox. 

 

But just in general, there are two options.

1. Use the MouseUp on the checkbox to fill or delete the text box. This works when the text box has only one source of data, that being the single checkbox.

2. Use a calculation script on the text box. This works for when the text has several sources. such as several checkboxes. 

 

What's your situation?

Hello Tom,

I am working a form and with request to include a drop down list selecting A, B, C, D. However, when selecting B an alert/text should pop up. Selected C a different alert and for D another alert.  So now, I created a checkbox for each A, B, C, D  and hoped to add a script to each checkbox with individual popup alerts/texts.  I've named my checkboxes TTL CDC so they are not checkbox1, checkbox2,

I've tried others, but ended up with those two below. That do not seam to work.

f.setAction("MouseUp","app.alert('Change pricing on customer account - no JQ necessary!');");

 

if (event.target.value == "Yes")

app.alert("Message", 3);

 

I have been reviewing and customizing quite a few options, but some guidance would really help.

Thank you for your time.

First, the "setAction" function is only used scripts for creating document, never in a working PDF. So don't use it.

 

You're second script uses the correct form, it should be used on the MouseUp event of the checkbox. 

 

if (event.target.value == "Yes")  app.alert("Message", 3);

 

So exactly what is the issue?

Hi Tom,

1. I created a chebox in the form called CDCBuys, that when you check it it should pop up and alert stating: Change pricing on customer account - no JC necessary!

Currently, I have the scrip below for this scenario, but nothing happens when I click the checkbox.

Upper Menu

Select Trigger: MouseUp / Run a JavaScript

Actions

-MouseUp

Run a JavaScript

if (event.target.value=="Yes")

  app.alert("Message",3);

2. The other scenario is that when a differnt checkbox named "Other" is selected, a textbos should aprear to enter text.

I hope this explains it better. If you wish, I can privately send the form for review.

Thank you,

Beate

1. Is the export value of the checkbox "Yes"? If its not, then this scirpt won't work.

2. Are there any errors reported in the Console Window?

You'll find a tutorial on the Console here:

I appreciate your continued suppoert and the tutorial, too.

Just add onto your existing code, either before or after the alert.

Here's an article on this topic:

Hello again,

I looked over the great informational links you sent. Thank you. I've applied working in the console now. However, I don't seam to get any debugging suggestions only the lovely undefined.

 

I have been sucessful to hiding a checkbox ("CHG") when checkbox ("New") is selected, but I can get it back to a visable presence if the ("New") is unselected.  I don't know if it matters, but the ("CHG") checkbox has the script running we've talked at in the beginning. so it is mouse up, JS. 

Do you have any suggestions?

I've been finding lots of other tutorials, but (as a total beginner in this field) customizing those scripts leaves me resultless.  

Thank you so much for your time.

Please post the code for the Mouse Up script in the "New" checkbox. The CHG code shouldn't matter unless it is affecting it's own visibility.

Here is one of the last ones. I overwrote the first one that half the job.

//Document-level function
function cbControl(){

  //Get a reference to each check box
  var f1 = getField("New");
  var f2 = getField("CHG");

  //hide CHG if New was selected
  if(event.target===f1||event.target===
  f2.value = "off";
  return;
  }
  
  //Uncheck New
  if(event.target===f1event.target===
  f2.value = "Yes"
  }
}
var visable = event.target.isBoxChecked("New")(1)display.hidden:display.visable; 
this.getField("CHG").display=display.hidden;
}
else
(event.target.isBoxChecked("New")(0)
Display.hidden:display.visable
{
this.getField("CHG').display=display.visable
}

As the code is shown in the post, it could not possibly do anything. There are many many syntax errors. 

Is this code correct, or was there an issue pasting the code to this message?

 

It also looks massively over complex for what it is supposed todo.

And you didn't say exactly where the function is called, please state this everytime you post code.

Thank you for your patience with me.  I figured as much. I've copied that from several sites. I wish I hadn't wrote over the first JS that worked to hid, but not made the CHG button visable again.

I have tried this one, but it didn't bring back the checkbox (CHG) after the checkbox (New) is deselected.

Function= if checkbox("New") is selected, then hide checkbox("CHG"). else, if checkbox("New") is deselcted, unhide checkbox ("CHG).

this.getField("CHG").display = (this.getField("New").value=="Off") ? display.hidden : display.visible;

 

Is this what you referred to add?

Thank you,

Beate

That is the correct script, but you didn't say where this script is located.

If it is in the MouseUp for the "New" checkbox, then this code will work;

 

this.getField("CHG").display = (event.target.value=="Off")?display.hidden : display.visible;

Sorry, I missed that. Yes, it is in the Mouse up in the ("New") checkbox.

 

I tried the script it dues the hidden/visible display for ("CHG"), except for the opposite of what it should be.  when New is selected CHG to be hidden.  otherwise CHG visiable.

 

this.getField("CHG").display = (event.target.value=="Off")?display.hidden : display.visible;

I  tried to replace "off" with yes and reversed the hidden visible. No luck.

So close!

Thank you,

Beate

That is very strange. I tested the script and it works fine. The unchecked value of any checkbox or radio button group is "Off", verbatim. Which means that display gets hidden. If you are going to change the condition, then make sure it is set to the exact export value.  

 

If the oposite is happening of what this code is indicating, and you changed the condition and that didn't change anything. Then it is likely the visibility is being controlled by another script.

Is there any other code in your form that could be affecting the visibility of the checkbox?  Make sure all other code is removed.

That makes sense.

 

I've attached a pix of the check boxes.

 

the CHG checkbox has a mouse up JS that makes a field appear to enter the reasons. (highlighted)

 

the goal is not to be able to have both checkboxes checked at the same time.

But did you check for scripts that affect the visibility of the "CHG" field?  Use the "Edit all scripts" option to search for all scripts that reference "CHG", and delete them. Except of couse for the MouseUp on "New".
