POhow to generate a scrolling list from the selected item from a scrolling list
text
Body
copied!<p>I was tried to build a form. There is a scrolling list generated by perl CGI and the items will be extracted and processed by perl CGI as well. However, I am stuck at further improved this form. Because for some items, there are also different ways to process them. What I want is that when a user click on a item of this scrolling list, it will generate another scrolling list or pop-up list for more selections. And the user can further select from this scrolling list or pop-up list and the selection will be extracted and processed by Perl. I know this client-side work may have to be done by javascript. I know some javascript, at least can understand most of the code written in it, but I have no experience in writing them to process such event driven condition and combine the results with Perl CGI.</p> <p>Could someone tell me how to do this using javascript? Thank you. Xiaokuan</p> <p>For Example: I have a scrolling list by Perl CGI:</p> <pre><code>print scrolling_list(-name=>"animals",-values=>["dog","cat"],-labels=>{dog=>'dog',cat=>'cat'}); #This will generate a scrolling list of "dog" and "cat". What I want is when a user click on dog to make a selection, this scrolling list will generate another scrolling list or pop-up list such as: print popup_menu(-name=>"action", -values=>['walking','training'],-labels=>{walking=>'walking the dog',training=>'training the dog'}); </code></pre>
