Question

I have an array of words that gets shuffled into paragraphs using jQuery. I’m trying to add some commas “,” in between them. Ideally i need a single comma added to every 4th word but this is beyond my modest jQuery skills.

This is my code:

    $("#generatebutt").click(function() {

    var dumpStr = "";

    var numberOfWords = $('#length').val();
    var numberpara = $('#numberpara').val();

    for (var i = 0; i < numberpara; i++) {
        Shuffle(melbArray);

        for (var j = 0; j < numberOfWords; j++) {
            var theWord = melbArray[j];
            dumpStr += theWord + " ";
        }

        dumpStr = dumpStr.trim();
        dumpStr += ".<br/><br/>";
    }

    $("#dump").html(dumpStr);

});

Really hope you can help!

$("#generatebutt").click(function() {

var dumpStr = "";

var numberOfWords = $('#length').val();
var numberpara = $('#numberpara').val();

for (var i = 0; i < numberpara; i++) {
    Shuffle(melbArray);

    for (var j = 0; j < numberOfWords; j++) {
        var theWord = melbArray[j];
        if(j % 4 == 0){
            dumpStr += theWord + ",";
        }
        else {
            dumpStr += theWord + " ";
        }
    }

    dumpStr = dumpStr.trim();
    dumpStr += ".<br/><br/>";
}

$("#dump").html(dumpStr);

});
