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

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?

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";

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"()()

{

}
