I have had the following problem with Ajax for a few days, and have not been able to solve it even after a few suggestions :
- The two files I mention here are copied at the end of this mail, so anyone can look if necessary.
I have a main document called : main.php
and a sub-document called : SubOne.php
My intention is to :
1) Bring the contents of SubOne.php into the area defined by the DIV tag named "MyDiv" when I press the button (in main.php).
2) Use the "Form Button" inside SubOne.php to change the text from :
"This is the subwindow one. We did not get any message"
to :
"This is the subwindow one. We got a message"
The first part works OK, but the second part does not work the way I want.
When I push the "Form Button" the text changes, but it reloads using the whole window. I want the text to change while staying in the MyDiv area and leaving alone the top part of my main.php window.
Can someone tell me what I need to change to make it work.
Thanks in advance for any tip or suggestion.
