Hi, everyone!

Here are some codes discussing html span tag used
with innerHTML tag. Who can show me the function
of the piece of codes here?


Codes:
--------
<img id='obj1' style='cursor:hand' src='1.gif'>
<img id='obj1' style='cursor:hand' src='11.gif'>
<a class = item href = "test1.jsp"> abc </a></br>
<span id = 'span1'></span>
<img id='obj2' style='cursor:hand' src='2.gif'>
<img id='obj2' style='cursor:hand' src='22.gif'>
<a class = item href = "test2.jsp"> cba </a></br>
<span id = 'span2'></span>
--------

In some other places,

Codes
--------
span2.innerHTML='<div align=left>Uploading...</div><br>'
--------


Who can explain the meaning and function of the two pieces
of codes here? (I think it is used to insert html scripts between
<span id = 'span2'> and </span>, but I am not sure.)


Thanks in advance,
George
