Question

I’ve grown spoiled by ColdFusion’s lists, and have run across a situation or two where a comma delimited list shows up in Javascript. Is there an equivalent of listFindNoCase('string','list'), or a performant way to implement it in Javascript?

Oh, and it should be able to handle list items with commas, like:
( “Smith, John” , “Doe, Jane” , “etc…” )

That’s what is really tripping me up.

Answer 1

You can use indexOf combined with .toLowerCase()

var list = '"Smith, John" , "Doe, Jane" , "etc..."';
if(list.toLowerCase().indexOf('"Smith, John"'))

If you need an exact match, like “Smith” when “Smithson” exists, just pad the strings with your delimiter. For example, let’s say your delimiter is a semi-colon (because you have commas in your string), pad the left and right sides of your string like so:

";Smith, John;Doe, Jane;"

Also pad the search value, so if you’re looking for Smith, the value would become:

";Smith;"

.toLowerCase().indexOf() would return -1 (not found). But ";Smith, John;" would return 0
