Capitalize first letter of Every Sentence in Textfield

[jmcrambo]

Hello All,

I am looking for a way to capitalize the first letter of each sentence within a textfield of a custom form in Acrobat. This can be done once the user finishes entering their entry. I do not want any other text changed except the first letter, of every sentence separated by a period and a space. Any help is appreciated. Thank you!

Use this as 'Validate' or On Blur script:

var text = event.value;
var sentences = text.split(". ");
for (var i=0; i<sentences.length; i++) {
sentences[i] = sentences[i].charAt(0).toUpperCase() + sentences[i].slice(1);}
var newText = sentences.join(". ");
event.value = newText;

Is it a multi-line field? Should happen if the user presses Enter without a period at the end of the sentence? Or if the sentence ends with a question mark, or an exclamation point?

Yes multi-line text box. Multiple senetences. Data is entered in paragraph form. Basically looks for when they click to the next field, the magic happens. There should not be any question marks or exclamation points in this field however we can include, if easy.

Then use the code provided above.

Try this. It's much simpler.

event.value = event.value.replace(/\b[^\.]*/gm, ((a)=>a.replace(/\w/,(b=>b.toUpperCase()))));
