问题描述

I have panel control.That control have both side next and previous button control. How I can change image by pressing buttons.

推荐答案

我建​​议使用jQuery.

处理按钮单击事件:
http://api.jquery.com/click/ [ http://api.jquery.com/attr/#attr2 [ http://docs.jquery.com/Tutorials:How_jQuery_Works [ http://docs.jquery.com/Tutorials [ http://docs.jquery.com/Main_Page [

I would advise using jQuery.

Handling a button click event:
http://api.jquery.com/click/[^].

Changing the image by changing the value of attribute src of the element img:
http://api.jquery.com/attr/#attr2[^].

If you are not well familiar with jQuery yet, I would advise to learn some jQuery if you want advanced JavaScript UI with good feature and maintainability. You can start here:
http://docs.jquery.com/Tutorials:How_jQuery_Works[^],
http://docs.jquery.com/Tutorials[^],
http://docs.jquery.com/Main_Page[^].
