Admin Javascript controller

An admin view template needs a Javascript controller to define how it interacts with the server-side PHP application that you are building. In this example, we are going to use BoostrapSlideShow (included in the system by default)

By default, we use EcmaScript 6 syntax for class declaration. This class must inherit from SCHLIX.CMS.BaseController and at the very least implements the constructor() and the runCommand (command, evt) method. If you need to run something after the DOM is loaded, simply implement the onDOMReady() method like the example below.

/**
 * View Controller class
 */
SCHLIX.CMS.BootstrapSlideshowAdmin = class extends SCHLIX.CMS.BaseController  {  
    /**
     * Constructor
     */
    constructor ()
    {
        super("bootstrapslideshow");
    };



    /**
     * Datatable row format: item title
     * @static
     * @param {type} elCell
     * @param {type} oRecord
     * @param {type} oColumn
     * @param {type} oData
     * @param {type} oDataTable
     * @returns {undefined}
     */
    static formatDataTableCell_Image (elCell, oRecord, oColumn, oData) {

        var field_title = SCHLIX.Util.isUndefined(this.parentControl.element_data["field-item_title"]) ? "title" : this.parentControl.element_data["field-item_title"];
        var odata_id = oRecord.getData("id");
        var odata_cid = oRecord.getData("cid");
        var odata_ext = oRecord.getData("extension");
        var file_exists = oRecord.getData("file_exists");
        var itemTitle = oRecord.getData(field_title); // oRecord.getData("title");
        var itemLink = site_httpbase;
        if (itemTitle == null)
        {
            SCHLIX.log("formatDataTableCell_DefaultTitleColumn cannot process a null title", 'warn');
            return;
        }
        if (itemTitle.length > 40)
            itemTitle = itemTitle.substr(0, 40) + '...';

        var app_name = this.parentControl.app_name;
        if (odata_cid > 0)
        {
            SCHLIX.CMS.__default_formatFolderInDataTable(app_name, elCell, oRecord, itemTitle, site_httpbase + this.parentControl.schlix_application_url + 'action=editcategory&id=' + odata_cid);

Note: As of October 2016, due to unavailability of documentation tools that can properly parse EcmaScript 6, information about SCHLIX.CMS.BaseController has not been posted yet. Once it is available, we will post an update to the documentation section of this site.
