Control Interfaces

• Init()
  Set some member variables. Usually the function RequestableControlInit can be used. The most important variables are:
  • data
    The object containing the data from server.
  • id
    The ID of the control.
• portlet
  See chapter “Portlet Object”.
• Render(output)
  Writes the HTML of the control into the output object and potentially adds events to the portlet object (see chapter “Events”).
• GetFscArgs()
  Defines the arguments e.g. needed to show a context menu.

Example:

function ajaxMyControl()
{
  this.Init = RequestableControlInit;
  
  this.Render = function MyControlRender(output)
  {
    var portletid = this.portlet.GetId();
    output.Push("<div id=\"MyControlContainer"+this.id+portletid+
      "\" class=\"FscMyControl\">...</div>");
  };

  this.GetFscArgs = function MyControlGetFscArgs()
  {
    if (this.fscargs === undefined) {
      var container = window.document.getElementById(this.id+
        this.portlet.GetId());
      this.fscargs = new VAPPArgs(null, ";"+this.portlet.GetObject()+";;"+
        this.data.GetAttrdef()+";"+this.data.GetFscargs(), this, container);
    }
    return this.fscargs;
  };
}
