    [CLOSED] How to get custom config parameters into JS function?

    Hello

    I call on a window creation this code :

                                    <Listeners>
                                    <Show Fn="showChartBacklog()">
                                       <CustomConfig >
                                            <ext:ConfigItem Name="Chart" Value=this.ID Mode="Raw" ></ext:ConfigItem   >
                                        </CustomConfig>
                                    </Show>
                                </Listeners>

    Hi @feanor,

    This way:

    Example
    var showChartBacklog = function (/* all the arguments here*/ eOpts) {
    console.log(eOpts.Chart);
};

    Why don't you want to pass required arguments directly to fn?
    <Show Handler="showChartBacklog(this.id);">

    Bacause I had problem and I think it was related to that parameters.

    I have to explain:

    I do that:


    Show Fn="showChartBacklog("wndChart")"
    It works on dev side, but not when I run from IIS server, I have a message : "showChartBacklog didn't exists" . I think it was about the parameter send mode, but in fact no, In showChartBacklog function I define a variable like that :

    Var Height;
    and later in code I do something like that:

    Height=300;
    To make it works on the production server (IIS 5) I have to define var like that:

    Var Height=0;
    If you know why...Just for personnal culture.

    Does it really work for you?
    Show Fn="showChartBacklog("wndChart")"
    I think there should be a parser error here.

    Yes it works, even with more parameters

    but wrote like that:

    Show Fn="showChartBacklog('wndChart')"

    Yes, there is no a parser error with single quotes, but a function is executed when a page is just loaded.

    I think a Click listener should not be executed without actual clicking. What do you think?

    Example
    <%@ Page Language="C#" %>
 
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>  

<!DOCTYPE html>

<html>
<head runat="server">
    <title>Ext.NET v2 Example</title>

    <script>
        var onClick = function () {
            alert("onClick");
        };
    </script>
</head>
<body>
    <form runat="server">
        <ext:ResourceManager runat="server" />
        <ext:Button runat="server" Text="Test">
            <Listeners>
                <Click Fn="onClick('test')" />
            </Listeners>
        </ext:Button>
    </form>
</body>
</html>
    Generally, Fn expects a function name Fn="onClick" or a full definition
    Fn="function () { alert('Hello!'); }"
    If you need just some JavaScript code, then you should use Handler instead of Fn.
    <Click Handler="onClick('test');" />
