Delete everything from menuitem array

I know that the ability to remove items from a menu dynamically after the menu is loaded is on the feature request list, and that the hide a menu item will not work for me.

I don't suppose anyone knows which array I could nuke (length=0?) to remove all of the items from a menu? I could then add items back in using the insertitem dynamically as I need them. I was trying to modify the insertitems script, but quickly found that I was over my head. Basically, I'd love a similar script that would allow me to call menuname.nuke() and it would remove all items from that particular menu array. I could then use the excellent insertitem to repopulate it. (Never would it remain empty).

Any ideas?

Here is a beta of a function that will remove a menu item from an already built menu:

I'm now working on the insertItem funciton - Could have sworn I'd already written this but cannot seemto find a reference to it anywhere. Please let me know where it is if you can find it.

Cheers

Code:

function mm_deleteItem(_mN, _iN) 
{
   _mnu=getMenuByName(_mN)
   _ii=_m[_mnu][0][_iN-1]
   _tA=_nA()
   for(_r=0;_r<_mi.length;_r++)
   {
      if(_r!=_ii)_tA[_tA.length]=_mi[_r]
   }
   _mi=_tA
   _tA=_nA()
   
   _cnt=0;
   for(_r=0;_r<_m[_mnu][0].length;_r++)
   {   
      if(_m[_mnu][0][_r]!=_ii)
      {
         _tA[_tA.length]=_m[_mnu][0][_cnt]
         _cnt++
      }
   }
   _m[_mnu][0]=_tA   
   
   
   for(_r=_mnu+1;_r<_m.length;_r++)
   {
      for(_p=0;_p<_m[_r][0].length;_p++)
      {
         _m[_r][0][_p]--
      }
   }
      
   for(_r=0;_r<_m.length;_r++)
   {
      _m[_r][23]=0
      _gm=gmobj("menu"+_r)   
      if(_m[_r][7])
      {
         _gm.innerHTML=_drawMenu(_r)
      }
      else
      {
         _gm.innerHTML=""
         _fixMenu(_mnu)
      }
   }
}

Syntax is mm_deleteItem('MENUNAME', ITEMNUMBER)

ie, mm_deleteItem('Main Menu', 3) will delete the third item in the main menu

(showing my ignorance here)

How does one use this code to remove items? Do I put it in a new page? If I have to ask, I probably shouldn't be thinking about using it

Thanks so much, but...

I really appreciate you sharing the remove script and I have several areas I can immediately use it!

However, I was wondering if there was an easy way to accomplish my original task of erasing all of the items from a particular menu. Or, alternately I could use the remove script your provided if there was a way to query how many items there were in a particular menu (the length of the appropriate array?)

Thanks for your help!
