How do I access the properties of a Tridion component such as the schema name it is based on in the aspx page?

I am customizing the ribbon toolbar by adding a button to it in TRIDION 2011 SP1. When I click on the button, it will open the aspx page. Inside this aspx page, I need to access the name of the schema used to create this component before creating the component itself (I mean, creating the component itself).

Please provide me with a way to resolve this issue. Thank you in advance.

You have to pass it to the popup. The scheme URI is available in the Component model object in the CME - so your button command can access it and pass it to a popup (for example, in a URL).



var schemaId = $display.getView().getItem().getSchemaId();

If you have a component (as an object) you can get its schema id as Peter pointed out. If you only have a component ID, you can load the component and navigate through it to the schematic.

When you need to load any element, you need to know that this is not a synchronous call in the API of the interface, so you should use delegation methods for this. For example, something like this:



Example.prototype._loadItemInformation = function Example$_loadItemInformation(itemId, reload) {
    var item = $models.getItem(itemId);
    if (item) {
        var self = this;
        function Example$_loadItemInformation$_onItemLoaded() {
            $evt.removeEventHandler(item, "load", Example$_loadItemInformation$_onItemLoaded);
            // proceed with the actions on the loaded item here
        };

        if (item.isLoaded(true) && !reload) {
            Example$_loadItemInformation$_onItemLoaded();
        }
        else {
            $evt.addEventHandler(item, "load", Example$_loadItemInformation$_onItemLoaded);
            //$evt.addEventHandler(item, "loadfailed", Example$_loadItemInformation$_onItemLoadFailed);
            item.load(reload, $const.OpenMode.VIEW);
        }
    }
};

Also be aware that the element may not load, you must also register an event handler for loadfailed (as my example code does).
