Help with break statement

[Abhijit Das7]

Hi Everyone,

I have a string, when I convert this string into array. The last element of the array is empty; I want to break the for loop when element is empty. Please help me with the issue.

sting = John, \n Guest 1, \n Guest 2, \n

var result = ' ';

var array = string.split(' , ');
for( var i = 0 ; i < array.length ; i++){

result +=  array[i] + 'joined the session';
}

 result += "";

 Thanks

Hello @Abhijit Das7 

use below script:- If empty means = '' or whatever you can replace accordingly. 

sting = John, \n Guest 1, \n Guest 2, \n

var result = ' ';

var array = string.split(' , ');
for( var i = 0 ; i < array.length ; i++){

//ADD below two lines - if this is what you meant by empty
if(array[i]=='')
break;

result +=  array[i] + 'joined the session';
}

 result += "";

Kindly mark my answer as helpful and accept solution if it helped you in anyway. This will help me be recognized for the efforts and also move this questions from unsolved to solved bucket.

try this and it worked for me

var string = "John, \n Guest 1, \n Guest 2, \n";
var result = '';

var array = string.split(', \n');
for (var i = 0; i < array.length; i++) {
    if (array[i].trim() === '') {
        break; // Break the loop if the element is empty
    }
    result += array[i].trim() + ' joined the session\n';
}

gs.info(result);

Output:

Hello @Abhijit Das7 ,

Added a pointer to count the length of array and stored with less one value.

var sting = "John, \n Guest 1, \n Guest 2, \n";

var result="";

var array = sting.split(',');
var leg = --array.length;   //storing the array length -1
for( var i = 0 ; i < leg ; i++){
result +=  array[i] + 'joined the session';
}
 gs.print(result);

Output:

Is this the desired output.
