How to get the component and component template tcm id using JavaScript?

Question

I need to take the Component and Component Template tcm ids from the Component Presentation tab of any Tridion Page.

Scenario:

On the exisiting page in Tridion.
Go to "Component Presentation" tab.
When I click the "Insert" button, I want to iterate the Component and Component Template tcm id and display that in JavaScript alert box.

I am trying to find the exact javascript file/function to accomplish this, I couldn't find the exact one.

I am using SDL Tridion 2011 SP1.

Any help/suggestion would be highly appreciated.

EDIT

I am having this script which will fire when we wil click the Insert button in the "Insert component presentation" window.

Tridion.Cme.Views.InsertCpDialog.prototype.onInsertClick = 
                    function InsertCpDialog$onInsertClick()
{
  var p = this.properties;
  var c = p.controls;
  var templateId = c.templateSelect.getValue();
  var components = c.list.getSelection().getItems();

  p.componentPresentationsAdded += components.length;

  var compId = components[components.length - 1];
  var component = $models.getItem(compId);
  if (component)
  {
    var userSettings = Tridion.UI.UserSettings.getInstance();
    if (userSettings && userSettings.isLoaded())
    {
      Tridion.UI.UserSettings.setLastSelectedLocation(
          component.getPublicationId(), $const.ItemType.COMPONENT, p.contextUri);
    }
  }

  this.fireEvent("insert", {
    components: components,
    template: templateId
  });
};

So here I will get the tcm id of selected Component and template "compId" & "templateId", which is to be inserted. Now my question is: how can I check whether this component and template is already present on the Component Presentation Tab?

If somehow I will be able to get the id of all component and template already present on the page (from my "Insert" button) then I can compare them. But I am not getting any function which will give me those id. Here I got stuck.

EDIT

I am trying to go inside the page with these codes but i am not able to get the correct function which is getting fired on click of Insert, or which will return me the list of component and template id listed there.

Extensions.Test.prototype.isEnabled = function Test$isEnabled(selection) {
  try
  {
    console.log($controls);
    var masterTabControl = $controls.getControl($("#MasterTabControl"), 
                                            "Tridion.Controls.TabControl");

    console.log(masterTabControl);
    alert("Mastercontrol - ComponentpresentationsTab");
    console.log(masterTabControl.getPage("ComponentPresentationsTab"));
    console.log("list of component presentations");
    console.log(masterTabControl.getPage("ComponentPresentationsTab").
                             getListComponentPresentations().getItems());
    console.log("list of get xml");
    console.log(masterTabControl.getPage ("ComponentPresentationsTab").
                             getListComponentPresentations().getItems().getXml);
  }
  (catch exc)
  {
  }
  return true;
}

EDIT I got all the CP Id listed under CP TAB with this code. Thanks to @Frank van Puffelen

var p = this.properties;
var tgp = this.properties;
var c = p.controls;

var pageId = selection.getItem(0);
var masterTabControl = $controls.getControl($("#MasterTabControl"), 
                                            "Tridion.Controls.TabControl");
var compPresTab = masterTabControl.getPage("ComponentPresentationsTab");
var comPresList = p.compPresTab.getListComponentPresentations(); 
for (var i = 0; i <= myStringArray.length; i++) 
{     
  console.log(comPresList.getItems()[i].getComponentId());
  console.log(comPresList.getItems()[i].getComponentTemplateId());     
}

How about you show us the code that you already wrote and where you are stuck? — Frank van Puffelen

If you don't provide more information about what you have already done, you run a good chance that this user account will get locked out of asking questions similar to what happened to @user1518281. Stack Overflow is not meant to turn your list of requirements into a working piece of code that you can copy/paste into a solution. We can help you do your work, but only if you show us what you've already done. — Frank van Puffelen
Did you write this code? It looks you copied standard InsertCpDialog.onInsertClick method. Do you understand what this code does? If not: did you set a breakpoint in it and step through it? You'll see that it gets access to a controls array that contains all the controls in the view (in this case the InsertCpDialog popup). This logic is applicable in any view, so you can just follow the trail. — Frank van Puffelen
No i didn't tell like i write this code.I got this while debugging the site and searching for the function which is getting triggered on click of "Insert"(on the InsertCpDialog Popup) button. So i am trying to do the same for the Insert button which is Present under CP Tab on page. So i am trying to dig inside — SDLBeginner

Once you have the Component Presentations tab of the Page dialog, you can get the list of Component Presentations like this

comPresList = compPresTab.getListComponentPresentations();

You can inspect the list in XML format like this:

comPresList.getXml()

Or, as you seemingly are trying in your code snippet, you can get the items themselves using:

comPresList.getItems()

This will give you a list of Tridion.ContentManager.ComponentPresentation objects, each of which you can call getComponentId and getComponentTemplateId on.

comPresList.getItems()[0].getComponentId()
comPresList.getItems()[0].getComponentTemplateId()

I got this information by taking the snippet that John Winter provided you earlier, pasting it into a Chrome JavaScript console and then doing a few text searches on the source tree (on disc) for key phrases such as "insert" (to find all handlers for the insert event) and ComponentPresentation = (to find the ComponentPresentation class).
