Is there a way to export last word of a string into a new field?

Correct answer Nesa Nurani

Use this:

var str = this.getField("Text1").valueAsString;
var xstr = str.split("");
xstr.push(xstr.shift());
ystr = xstr.join("");
event.value = ystr;

I have a text field (text1) with a sentence of 8 words. I am trying to display each word in a different text fields from text2 to text 9 (1 word/ field). I am a beginner using PDF and Scripts, but I really appreciate detailed explanation to do that.

Thank you.

You can use this (assuming all words are separated by space character) as validation script of "text1" field:

var str = event.value.split(" ");
for( var i=0; i<=7; i++){
this.getField("text"+(i+2)).value = str.length == 8 ? str[i] : "";}

    Hi Nesa,

    I already paste the script as validation script of "Text1" field, but fields from Text2 to Text9 still empty. What can I do to populate each word in the respective fields?

    Thank you.

    Hi, I have additional question. In my text field "Text1" I have a string that starts with a letter and end with a number.
    I want to show this in second field but I need letter to be next to a number. e.g. original text: "X some text 1234"
    new text: "some text 1234X".

    You can use this code as validation script of a field where text is:
    this.getField("Text1").value = event.value.split(" ").pop();

    Change field name if needed.

      Thank you so much. I have additional question.
      In my string first and last word are numbers. How would I extract both numbers and then join them,
      but numbers from end of the strings should be first?

      Just add this '+event.value.split(" ").shift();' to the code like this:
      this.getField("Text1").value = event.value.split(" ").pop()+event.value.split(" ").shift();
      TIP: split(), splits string into array.
      pop(), removes last element of array and returns that element
      and shift(), removes first element of array and returns that element.
