combining two variables

[Martin9899]

Hi,

i have this code that revrites multiple textfields into one. i need to change variable i into a1, a2 or a3 depending ond the value of i.

//final text should look like this

//text10: loan1

//text20: loan2

//text30: loan3

CODE:

a1=("text10");
a2=("text20");
a3=("text30");

var text = "";
for (var i=1; i<=3; i++) {
var s = this.getField("loans"+i).valueAsString;
if (s!="") text+=""+ i +  ": " + s + "\r";
}
event.value = text;

You should put the names of the fields in an array, and then iterate over it in your for-loop.

do you mean like this? its not working, but i have never worked with arrays before 😞

var fields = ["jedna","dva","tři"];

var text = "";
for (var i=1; i<=3; i++) {
var s = this.getField("PUJCKY"+i).valueAsString;
if (s!="") text+=""+ fields[i].value + ": " + s + "\r";
}
event.value = text;

You need to better explain how this should work. Are there two sets of fields, or just one?

[Martin9899]

there are 3 or more fields converted into one. But to each line i need unique start. for example

field1 contains text 10.000

field2 contains text 100.000

field 3 contains text 1.000

field 4 need to contain all three field but with unique text as line identification in this case it should like this

loan: 10.000

mortgage: 100.000

credit card: 1.000

loan, mortgage and credit card are not fields but variables depending on the number of the line. In this case its variable i

a1="loan";

a2="mortgage";

a3="credit card";

var text = "";
for (var i=1; i<=3; i++) {
var s = this.getField("AMOUNT"+i).valueAsString;
if (s!="") text+=""+ ?? + ": " + s + "\r";  //if i=1 then use a1, if i=2 use a2, if i=3 use a3
}
event.value = text;

but bernd Alheit code works, its just more complicated then i thought. I thought i can use i variable in for loop to identify variable a1-a3

Try this:

a1=("text10");
a2=("text20");
a3=("text30");

var text = "";
for (var i=1; i<=3; i++) {
  var s = this.getField("loans"+i).valueAsString;
  if (s!="") {
    var txt;
    if (i == 1) txt = a1;
    else if (i == 2) txt = a2;
    else txt = a3;
    text+=""+ txt +  ": " + s + "\r";
  }
}
event.value = text;

thanks this one works like a charm.  if variable i will be for example from 1 to 20 the code will build up.. but it should work as well, thanks.
