Hello guys:

I have two questions. I’m programming an online game with PHP and I need two things:

a) Let’s suppose that var x has value 3. Then, with clicking in a link, x should increment by 1 and it should be showed instead of 3.

Example (this represents the screen):

———————–

Value: 3

Click here to increment
———————–

–after click–>

———————–

Value: 4

Click here to increment
———————–

So, how would yo do it?

b) I need that when pointing in a link (so, onHover event?) the info in a frame is changed. So, if we have links a and b, when pointing at link a the text in the other frame should be ‘aaaaa’ and when pointing at b the text should be ‘bbbbb’ (but without reloading the frame).

As you see, I’m completely ignorant in Javascript. I hope you help me ?

Greetings from Girona, Spain.
