    How Update control Ext: Label from Javascript

    As you may have noticed, recently I iciandome with ExtNet's cool.

    Well, I have some doubts about how to update a control Ext: label from javascri

    Code Page.aspx
    <body>
    <ext:ResourceManager ID="ResourceManager1" runat="server">
    </ext:ResourceManager>
    <form id="form1" runat="server">
    <ext:Label ID="lblTestEN" runat="server"></ext:Label>
        <br />
        <ext:Button ID="btnTest" runat="server" Text="Click me" >
            <Listeners>
                <Click Fn="updateLabel" />
            </Listeners>
        </ext:Button>
    </form>
</body>
    Function for update Label
    <script type="text/javascript" language="javascript">
        var updateLabel = function () {
            var msg = "Updated!!!"
            lblTestEN.update(msg);
        };
    </script>
    It also works as follows
    Ext.fly("lblTestEN").update(msg);
    I would like to know the difference between the two ways to perform the update of the value of the label and what is most optimal. There are other ways to update the value?

    Thanks for all...

    Hi FAFNER,

    The two techniques you posted work perfectly and either one will get the job done.

    That said, there is a third option of using the .setText() function.

    I'd go with the .setText() function as it will provide more consistency within the framework and forward compatibility.

    Example

    lblTestEN.setText(msg);
    Hope this helps.
