Hi,

I have put an onclick event on a textarea, and want to expand it and schrink it again when it's clicked.

Can someone explain to me, why this will only expand to 3 lines and not fold back?

onclick="if (this.rows==3){this.rows = 1}; if (this.rows==1){this.rows = 3};"

Your first if statement triggers if rows=3 and sets rows to 1.  After that triggers, your second if statement sees that rows is = 1 and sets rows=3.

You'll want to use an if-else statement so after the first if processes it doesn't move on to the next.

You are right, what confused me was it actually did execute the second part, rather than the first, when i did:

onclick="if (this.rows==1){this.rows = 3}; if (this.rows==3){this.rows = 1};"

Nothing happend at all.

But as you said:
onclick="if (this.rows==3){this.rows = 1}; else if (this.rows==1){this.rows = 3};"
Worked.

Thanks.
