    Question How to confirm SetPreferenceForKey() is actually working correctly

    Can't get SetPreferenceForKey() and preferenceForKey() to work.

    Save function:-

    function saveString( ) {
    var myString = 'This is a test string';
    widget.setPreferenceForKey(myString, "key");
    alert("String saved.");
    }


    Load function:-

    function loadString() {
    alert("Getting saved string.");

    var savedString = widget.preferenceForKey("key");
    if (savedString != null) {
    document.getElementById("txt").value = savedString;
    }
    }


    Using:-
    <a href="#" onclick="saveString()">save text</a>
    <a href="#" onclick="loadString()">load text</a>
    <p id="txt">This should get replaced.</p>

    I click the link to save a string, (get an alert looks like it's working) then click the link to get it and write to txt div, (get alert to say getting saved string) but nothing gets written.

    If I stick an alert after the if (savedString != null) syntax again, nothing happens suggesting the key / value isn't saved???

    I have no idea why this isn't working?

    using aptana.

    Any help would be really appreciated.
    Thanks,
    Si.

    hi

    replace line:

    document.getElementById("txt").value = savedString;

    with:

    document.getElementById("txt").innerHTML = savedString;
