Underlining a Single Word within a Text Field in Acrobat DC

[Angus24]

I would like to know if it is possible to underline a word within a text field. In my example below I want to underline the word MINOR: only.

This is my coding:

event.value="MINOR: " + this.getField(“BName”).valueAsString;

I want the above to look like this:

MINOR: Jane Doe

Is this possible?

Thank you

[Bernd Alheit]

This is possible. Use rich text format in the text field and the JavaScript span object.

[Angus24]

Thanks for your response Bernd, but I'm still at a loss on how to do this.

Can you help me out with the coding for this?

See the documentation at the link below

Acrobat DC SDK Documentation

Example 1 will show you how to underline some text.

Example 2 shows you the rest of what you need to do to construct a set of span objects that have different formatting and then set that as the rich text value. In your use case, you'd need two spans.

Hi Joel, thank you for the link. In looking at the link you sent, I don’t want to underline the text field BName in my example, I want to underline the text I’m putting in front of the text field. And after reviewing the information you sent I still don’t know how to do this. 

So my situation is this: my calculation script in text field Text 10 is:

event.value="MINOR: " + this.getField("BName").valueAsString;

I want MINOR: to be underlined not the text field BName

MINOR: Jane Doe

The info that you provided reads, to me, that the underline would be for the entire field of BName, which is not what I want.

Sorry, I’m  not understanding the information you provided.

[Joel_Geraci]

You'd create a span for "MINOR:" and set the properties to underline it. Then another span for the field value and set the properties for that.

Then you'll need to modify your calculation for Text 10 so that it sets the rich value of the field rather than the value of the calculation event. Use...

event.target.richValue = spans

...like in the example

[Angus24]

Okay, below is what I got out of the information you provided.

var f = this.getField("Text10");

var spans = f.richValue;

spans[0].underline = true;

f.richValue = spans;

var spans = new Array();

var spans = new Object();

spans[0].text = "MINORS: ";

spans[0].underline = true;

event.target.richValue = spans;

And my result is an empty text field.

I don’t know who to utilize the information you provided for my situation. Would it be possible for you to provide me with the coding?

[Joel_Geraci]

I could but you wouldn't learn anything for next time.

Take a look at this link and then revisit the problem.

In the Acrobat JavaScript Reference look at the sample of the span object.
