使用文本框的onfocus事件。然后让它调用一个更改按钮颜色的javascript函数。



W3schools.com有一个很好的交互方式来查看onfocus事件的工作原理。在这种情况下，他们会更改文本框颜色，但在此时更改按钮的颜色应该是微不足道的。

For future reference, a simple google search can help you out quickly.

Use the onfocus event of the textbox. And then have it call a javascript function which changes the color of the button.

W3schools.com has a good interactive way to see how the onfocus event works. In this case they change the textbox color but changing the color of the button should be trivial at that point.
