splitting multiple lists, then joining into single array

[davilu]

Hi Everyone, I have a question regarding comma separated lists and arrays.   Below is my simple server script that queries a Forms table and returns back all the forms listed for each row:

var docSet = new GlideRecordSecure('forms');
docSet.query();
while(docSet.next()){
         data.formType = docSet.getDisplayValue('form_type');
gs.addInfoMessage(data.formType);
}

The gs info message returns this, which is correct:

I want to split all of the comma separated items and return it all in the same array.

sampleArray = [ sf 61, sf306, sf2817, sf 2808, sf256, sf181 ]

I've tried samplelist.split(','), but can't seem to get it to work correctly.   Can someone help with this syntax?

So it is seeing each pair as a single element, which I don't know if that is what you want.   I think writing the values in a string with a += and then splitting it will give you 6 different elements, not 3 separate pairs.

In that case then, you need to use the split(',') just like others suggested and then loop it with indexOf to check the particular value.

var formTypeList = [];

var docSet = new GlideRecordSecure('forms');

docSet.query();

while(docSet.next())

formTypeList.push(docSet.getDisplayValue('form_type'));

var formTypeListarray = formTypeList.split(',');

for(var i = 0; i < formTypeListarray.length; i++ ){

if(formTypeListarray[i].indexOf('YOUR TEXT') > -1) //Returns -1 if the item is not found.

gs.addInfoMessage(formTypeListarray[i]);

}

Or you can use the JavaScript String indexOf() Method instead of JavaScript Array indexOf() Method to check if that particular string is there or not.in formTypeList

Hi David,

I don't know if this matters to your requirement, but I like to use an object as an intermediate to eliminate duplicates when building lists from multiple sources.

var docSet = new GlideRecordSecure('forms');   
docSet.query();

var uniqueForms = {};
while(docSet.next()){   
         var docSetForms = docSet.getDisplayValue('form_type').split(',');   
         //Using the value also as the key for uniqueForms{} will result in only one instance of any value.
         for(i=0;i<docSetForms.length;i++){
                 uniqueForms[docSetForms[i]] = docSetForms[i];
         }
} 

var listUniqueForms = [];

for(var m in uniqueForms){
       listUniqueForms.push(m);
}
var strList = listUniqueForms.join();

//Either return as an array (listUniqueForms)
//Or as a string (strList).

Thanks,

-Brian

Thanks everyone so much for the help!   mallen_nspi and wwar1ace, both your   methods work great, thanks!

Hey wwar1ace, I do have a follow up question if you have the time.   I did if(strList.indexOf(formReview.getDisplayValue('form_type'))>-1) from another table that has SF181, SF256, and SF1152 and it returned the correct forms (SF181 and SF256).   However when I do an indexOf to the array (if(listUniqueForms.indexOf(formReview.getDisplayValue('form_type'))>-1)), it only returns SF256.   Obviously I will use the indexOf to the strList, but is there a reason one works over the other?   Does indexOf perform different between comma separated lists and arrays?

This also happens with mallen_nspi's solution as well.

Thanks again to you both!
