Javascript where text in Text Box A will trigger a text in Text box B?

[B0nb0n12345]

Hello,

I've been trying to find a code in which a text in Text Box A will trigger text in Text Box B.  I am currently using a code that works when I type in the text on the form itself.  However, when I have the pdf file run through a program that pre-populates text in Text Box A, it won't trigger text in Text Box B.

I am using this code:

if (event.value!=" ") this.getField("Text Box B").value= 20

I am not sure if there something I have to change because text box A has a prepopulated text?

You can place your code as a doc-level script, so that it executes when the file is first opened.

But then don't use event.value but this.getField("Text Box A").value, instead.

Hello,

My code looks like this and I also placed it as doc-level script, but the text is still not showing up for Text Box B

if (this.getField("Text Box A").value=" ") this.getField("Text Box B").value= "20"()()

{

}

Why all the added brackets and parentheses? It's not necessary.

Also, you're using the wrong operator in your if-statement. The comparison operator of JS is ==, not =. That's the assignment operator.

Use this code:

if (this.getField("Text Box A").valueAsString==" ") this.getField("Text Box B").value = "20";

Hello,

I used the code you provided, but nothing shows up in text box B after I run the pdf through the program...

Are you sure the value of the field is a single space, and not nothing, for example?

Also, check the JS console for error messages.

Yes, im sure, and i even tested it on 2 other fields with actual text, but nothing

and no error messages

Where did you place the code, exactly?
Can you share the file (either privately or via Google Drive, Dropbox, Adobe Cloud, etc.)?

Hello,

i'll share the file via google drive.  I renamed some of the text boxes.
