This is for sharing purposes.

This allows a form in page to grab some fields from another post to include in the current post:

function MyFunction()
{
   ...
   loFormElement=document.Form1.elements
   lnElement=loFormElement.length
   for (lnCounter=0;lnCounter<lnElement;lnCounter++)
   {
      loElement=loFormElement[lnCounter]
      if (loElement.tagName=='INPUT')
      {
         if (loElement.type=='text')
         {
            loNewElement=loElement.cloneNode(true)
            loNewElement.type='hidden'
            loElementToFind=document.LXDataEntry.elements.namedItem(loElement.name)
            if (loElementToFind)
            {
               loElementToFind.parentNode.removeChild(loElementToFind)
            }
            document.LXDataEntry.appendChild(loNewElement)
         }
      }
      if (loElement.tagName=='SELECT')
      {
         loNewElement=document.createElement('input')
         loNewElement.type='hidden'
         loNewElement.name=loElement.name
         loNewElement.value=loElement.value
         loElementToFind=document.LXDataEntry.elements.namedItem(loElement.name)
         if (loElementToFind)
         {
               loElementToFind.parentNode.removeChild(loElementToFind)
         }
         document.LXDataEntry.appendChild(loNewElement)
      }
   }
   document.LXDataEntry.submit()
}

This takes all input fields as well as all select fields from Form1 and clone them into LXDataEntry form before the submit.

I also take only the input type text and change them into hidden fields to be posted in LXDataEntry. The same applies to the select. This avoid duplicating those fields as is in the bottom of the page and submit them transparently.

I also have support for removing those cloned fields before adding them. This is in case the page can post multiple times in order to avoid duplicate fields.
