Inline Editing Script for Scholastic, by Alex Mezheritsky

-- Text field/textarea must be initially hidden
-- Link has to call inline_edit(header/para id, textfield/textarea id, link id)
-- Textfield/area must have onblur event call inline_save(header/para id, textfield/textarea id, link id)
-- Textfield/area can call onkeypress inline_check("event" (without quotes), header/para id, textfield/textarea id, link id)    (this does nothing currently but could save the text if a certain key/combo is pressed)

Example of HTML :
<h3 id="header_div">Westward Expansion</h3><input id="editing" type="text" style="display:none; font-size: 14pt; font-weight: bold;" onkeypress="inline_check(event, 'header_div', 'editing', 'h3linky');" onblur="inline_save('header_div', 'editing', 'h3linky');">
<br><a id="h3linky" href="javascript:inline_edit('header_div', 'editing', 'h3linky');">Edit</a>
