Editor / Custom Modules

   
 
 
 
 
   

  • Creating a custom module

    The example shows how to create a simple module that displays the count of tables and images in the content area.

    To create a custom module register its tag in the Modules inner-tag of RadEditor. Please, note that at least one of the built-in modules should be registered when creating a custom module, because due to optimization purposes the editor will not register its modules javascript code if some of the built-in modules is not declared:

    <telerik:radeditor runat="server" ID="RadEditor1" Height="700px" >
       <Modules>
          <telerik:EditorModule Name="MyModule" Enabled="true" Visible="true" />
          <telerik:EditorModule Name="RadEditorStatistics" Enabled="true" Visible="true" />
       </    Modules>
    </telerik:radeditor>

    and after that implement the initializeBase function, e.g.

    <script type="text/javascript">
    MyModule     = function(element)
    {
         MyModule.initializeBase(    this, [element]);
    }

    MyModule.prototype     =
    {
        initialize :     function()
        {
            MyModule.callBaseMethod(    this, 'initialize');
            var     selfPointer = this;
            this    .get_editor().add_selectionChange(function (){ selfPointer.doSomething(); });
            this    .doSomething();
        },

        //A method that does the actual work - it is usually attached to the "selection changed" editor event
        doSomething : function()
        {
            var span = document.createElement ("SPAN");
            span.innerHTML = this.get_editor().get_html();

            var     imageCount = span.getElementsByTagName("IMG").length;
            var     tableCount = span.getElementsByTagName("TABLE").length;

            var     element = this.get_element();
            element.innerHTML = "<b>CUSTOM MODULE: Images: " + imageCount + " Tables: " + tableCount + "</b>";
            element.style.border = "1px solid red";
            element.style.backgroundColor = "yellow";
            element.style.color = "red";
        }
    }    ;

    MyModule.registerClass('MyModule', Telerik.Web.UI.Editor.Modules.ModuleBase);
    </script>
