I am creating a simple webpage with an image in the background and multiple comboboxes (<select> tag) for the user to select values. Here is one of the comboboxes:
<select style="position:absolute; left:919px; top:288px; background-color: blue; color: white;" id="cze us" class="us"> <option selected>0 <option>1 <option>2 <option>3 <option>4 <option>5 <option>6 <option>7 <option>8 <option>9 <option>10 <option>11 </select>
I need to work with these selected values further and as I am quite a noob in HTML/Web programming, I have these questions:
1. How could I add values in multiple comboboxes selected, e.g. 1,3,2,6,0 together to a sum value with a button click?
2. Or would it be possible to make the addition interactive - e.g. once the user selects a different value in a combobox, the sum would be adjusted?
3. How could I store the current selections in multiple comboboxes in a txt file on the server and then recall it later?
Thx!
