Question

So I would like to have a method inside my constructor. I call my constructor like this

new EnhancedTooltip($("taskPreview1"))

and define it as so

///<var> Represents the controls</var>
var EnhancedTooltip = function (toolTipObject) {

    ///<field name="alignment" type="Number">.</field>
    this.alignment = 2;
    ///<field name="associatedControl" type="Number">.</field>
    this.associatedControl = toolTipObject;
    ///<field name="caption" type="Number">.</field>
    this.caption = "Let's see how this works";
    ///<field name="description" type="Number">.</field>
    this.description;
    ///<field name="enableEffects" type="Number">.</field>
    this.enableEffects = false;
    ///<field name="fadeAnimationSpeed" type="Number">.</field>
    this.fadeAnimationSpeed = 500;
    ///<field name="image" type="Number">.</field>
    this.image;
    ///<field name="minimumHeight" type="Number">.</field>
    this.minimumHeight = 100;
    ///<field name="minimumWidth" type="Number">.</field>
    this.minimumWidth = 200;
    ///<field name="objectName" type="String">.</field>
    this.objectName = $("taskToolTip");
    ///<field name="padding" type="Number">.<field>
    this.padding = 5;
    ///<field name="tailAngle" type="Number">.</field>
    this.tailAngle;
    ///<field name="tailDiamensions" type="Object">.</field>
    this.tailDimensions = new Size(15, 0);

    EnhancedTooltip.init();

    this.init = new function () {
      ///<summary>Initializes the class EnhancedTooltip.<summary>

      console.log(EnhancedToolTip.objectName);
    };

  };

and getting the error that EnhancedTooltip has no method init. So how should I define init.

Also if I want to call other functions from init how would I do that. For example

this.addToolTipElements = function() {

    $("#workspaceContainer").append("<div id = taskToolTip class = taskToolTip</div>");

    this.objectName.append("<canvas id = toolTipCanvas class = toolTipCanvas </canvas>");


    this.objectName.append("<div id = toolTipCaption class = toolTipCaption>" + this.caption + "</div>");

 };

That’s because “EnhancedTooltip” is your constructor function, and it doesn’t have an “init” property. However, the object being constructed (this) does:

this.init();

and inside the function:

  console.log(this.objectName);

Also, it’s not new function, it’s just function:

this.init = function() {
  console.log(this.objectName);
};

edit ah and, as Sirko points out, call the function after defining it.
