How can I append a textarea value to run through an array

I have an array created by taking the values of all the links in a div, when I add the values to a textarea to send them to my server, it's o开发者_JS百科nly pulling the last one, using console I noticed that the array is holding all the values, as is the alert when I set it, so how can I concatenate all the values into one long string with commas or something? Here's my code

 $(".populate").click(function(){
   var array = $.makeArray( $('li.item-link a'));
   jQuery.each(array, function(index, value) {
     console.log("index", index, "value", value);
     alert(value);
     $("#CAT_Custom_196863").val(value);
   });
 });

Anyone any ideas?

Your $("#CAT_Custom_196863").val(value); line is setting the entire value to the latest value.

Instead use something like:

$("#CAT_Custom_196863").val($("#CAT_Custom_196863").val() + ', ' + value);

---

You can use the join method of Javascript arrays:

$("#CAT_Custom_196863").val($.MakeArray($('li.item-link a')).join(", "));

BTW Blair McMillan is correct, you're setting the entire value, not adding to it.

The val method replaces the current value. Try this instead:

$(".populate").click(function(){
   var array = $.makeArray( $('li.item-link a'));
   var newVal = '';
   jQuery.each(array, function(index, value) {
     console.log("index", index, "value", value);
     alert(value);
     newVal += value + ','; // comma?
   });

   // In order to skip the last comma, uncomment this line:
   // if(newVal.length > 0) newVal = newVal.substr(0, newVal.length - 1);

   $("#CAT_Custom_196863").val(newVal);
});

try

$.map(arr, function(value, index) {
    return arr.join(",");
});

rest is logic
