drop-down change display same page with lots of variables

[busystock]

i have a page with lots of drop-down variables(A). there is one different drop-down(B) a set of preset links with some of those A variables defined... How can I keep the selected B value and open the preset link?

thanks a lot.

If you are wanting to keep the results from A and use those to influence B (without reloading the page) then you are looking at a client side script.
Javascript will sort it out for you.

If you are wanting to keep the value of B when you load a new page then you could send it as a GET request. Something like example.com?b=myValue
You can then use $_GET['b'] to access that value on the new page.

I'm not sure exactly what you are asking, but hopefully either one of those answers your question.

i want to keep the value of B, not As.

<option value='aaa'>link a</option>

aaa is way too long. is there any other way to do that?

thank you.
