    Javascript how to ascertain if it is a comma delimited list? - Stack Overflow

    I'm curious, how would you test a string and say "yep, that is a ma delimited list!" I'm not so worried about the 'ma delimited' part more that this string has more than one item in it?

    Thanks, R.

    • 1 Are you trying to determine the difference from a string that is a probable csv and one that is a probably sentence? If so, the answer may be much more plicated than merely checking for one or more mas. – Mike Commented Jul 9, 2009 at 23:20
    • No, its not a sentence, but a list of items concatenated together, depending on a particular set of circumstances. – flavour404 Commented Jul 10, 2009 at 23:05

    Reset to default 11

    How about:

    stringObject.indexOf(",") >= 0

    To check if the string has more than one item, try something like:

    str.split(",").length > 1

    ... although, as suggested in a ment, correct parsing is likely to be bit more plicated than this for the general case.

    Edit:

    whoops, misread language as Java - sorry.

    Be very careful if you are just splitting on a ma for a csv list as fields can actually contain mas and are encased by quotes i.e.
    Name,Age
    "doe, jane",18
    "bob, jim",20

    If it isn't for a csv perhaps you should be using an array or an object to hold the values?

    You could also just go like:

    var words = yourString.split(',');
for(var i=0;i<words.length;++i) {
  doSomething(words[i]);
}

    Another solution:

    (string.split(",").length > 1)
