Question

<select multiple="multiple" class="listBox" name="drop1" id="toList">
    <option value="1">John Doe (1)</option>
    <option value="2">John Doe (2)</option>
    <option value="3">John Doe (3)</option>
    <option value="4">John Doe (4)</option>
    <option value="5">John Doe (5)</option>
</select>

I am trying to be able to grab every single option in this toList and build out a delimited list that I will then post to another page.

What is the most efficient way of doing this?

I thought of originally doing:

$(#toList).each(function () {
     var myList = myList + $(this).val();
    });

$.post('somepage.asp', userList: myList);

What is the best way to accomplish this?

Answer 1

This should work nicely:

var myList = []
$("#toList > option").each(function () {
  myList.push($(this).val());
});

$.post('somepage.asp', userList: myList.join(","));

Or if you only want the selected values:

var myList = []
$("#toList > option:selected").each(function () {
  myList.push($(this).val());
});

$.post('somepage.asp', userList: myList.join(","));
