    Retrieving list of names from list of name value pairs

    I have list of paired values, and i need to get the list of just the first item:

    Example:
    Input: CA: San Francisco, TX:Austin, CA: San Jose, GA: Atlanta, MA: Boston
    Output: CA, TX, CA, GA, MA

    Can someone help me with a Javascript snippet that achieves this? I am thinking on lines of using split and join, but I am getting confused, especially because the number of attributes in the original list is not fixed.

    <script>
    var Input='CA: San Francisco, TX:Austin, CA: San Jose, GA: Atlanta, MA: Boston';
    var arr=Input.replace(/\s+/g, '').split(',');
    var ext=new Array();
    for (i=0;i<arr.length;i++){
    ext[i]=arr[i].substring(0,2);
    }
    alert(ext.join(','));
    </script>

    hope it works for you

    "CA: San Francisco, TX:Austin, CA: San Jose, GA: Atlanta, MA: Boston".split(/:[\w\s]+/).join("") // == "CA, TX, CA, GA, MA"

    obj = {CA:"San Francisco", TX:"Austin", CA:"San Jose", GA:"Atlanta", MA:"Boston"};
    Object.getOwnPropertyNames(obj);
    >> ["GA", "CA", "MA", "TX"]

    p.s.:
    Only IE will preserve the original order, ie:
    ["CA"," TX", "GA", "MA"]

    And you have a problem there with double entry of CA key.
    You'll need to correct that.

    i.e.:
    CA: ["San Francisco", "San Jose"]
