Question

I have a string array variable called ‘myAttachmentArray[]’ which holds different figures like this:

[0] – 50000

[1] – 51010

[2] – 52000

[3] – 50010

And the array size is dependent on an int variable called ‘squadNumbers’

What I want to do, is to place all the ‘myAttachmentArray[]’ into another string variable called ‘currentAttachments’, but with a ‘,’ in between each array value.

So, currentAttachments would = 50000,51010,52000,50010 …

The only problem is that the array size is dynamic, so I can’t do:

currentAttachments = myAttachmentArray[0]+”,”+myAttachmentArray[1]…

So I tried a for loop:

for(var i = 0; i <= (squadNumbers - 1); i++){
    currentAttachments = currentAttachments + myAttachmentArray[i] + ",";
}

But I still don’t get what I want …Please help

Answer 1

You need to use join

currentAttachments = myAttachmentArray.join(",");
