Dropdown Issue in IE with Dynamically Populated SELECT Field (Bug??)

Discussion in 'Javascript' started by philaphan80@yahoo.com, Jul 20, 2005.

    Hello,

    I'm trying to dynamically load a list of teams into a SELECT field
    (dropdown / combo box) when a user clicks on the field. (The teams are
    pre-loaded into JS arrays via ASP/SQL -- not shown.)

    My problem is when I click on the box, the team loading *works*, but
    it's performing a funky action. Upon click, it drops down once and the
    teams are there. But in a split second (once the box drops down to its
    bottom limit) the screen flickers and the box rolls back up to its
    original state. (It almost appears as if I clicked twice on the box.)

    I've tried onclick, onmousedown, onfocus... none work right. I even
    tried appendChild with no luck.

    I'm using Internet Explorer to view the page and I'm only targeting IE
    since a very small number of users will be loading this page. I loaded
    it into Firefox, Netscape and Opera just for kicks, though -- Firefox
    and Netscape performed the action correctly and Opera didn't drop
    anything down at all. (Nice.)

    Anyway, is this a known bug in IE? Something I'm doing wrong? A
    combination? Any help would be appreciated.


    <select ... size="1" style="width: 175px;"
    onmousedown="loadTeams(this)">
    <option value="" selected></option>
    </select>

    <script>
    function loadTeams(e) {
    e.options.length = 0;
    e.options.add(new Option("", "", true, false));

    for (i=0; i < teamids.length; i++) {
    e.options.add(new Option(teams, teamids, false, false));
    }
    }
    </script>

    Why are you triggering the loading on clicking the select itself? You
    would be much
    better off having the optionsl oaded before the user interacts with
    the select.

    Usually, I would agree. That would make my job *much* easier. ;)

    There are several fields on the page and the users can only select the
    item once (no duplicates.) Pre-loading would lead to potential
    duplication. I could always check for that before submitting the
    form... but then a light bulb lit above my head and I thought it would
    be snazzier (that's right, I said "snazzier") to have the fields
    automatically load the remaining items on each click, thus eliminating
    the duplication and verification.

    The part that stinks the worst is that the logic works perfectly, but
    the browser seems to be doing something funky. I was wondering if
    anyone else ran into this (and possibly had a workaround......??)

    Great minds think alike. ;)

    Thanks for your help, Ted. I actually thought of the same thing
    yesterday and implemented it. Works great!

    I think what I'm experiencing is a bug or a "quirk", if you will, in
    Internet Explorer. I left my original code in the page (commented out)
    since it's a lot smaller than the workaround. But after running some
    more tests on IE, hope for an actual solution is fading. It seems to
    be the way the actual browser behaves and not something I'm doing.

    Thanks again!
