html - Drop down menu variable divs show on page load -

-

just need little on haven't been able find answer to. have drop down menu in html supposed display div image associated when drop down selection made. problem currently, load every div when page opens , hide divs when selection made. nothing shown until actual selection made if makes sense. here have far (simplified problem's sake):

<select onchange="toggle_form_element(this)" name="parts" id="parts">   <option value="-">please choose image</option>   <option value="0">img 1</option>   <option value="1">img 2</option>   <option value="2">img 3</option> </select> <span id="dropdown">   <div id="img1">image 1.jpg</div>   <div id="img2">image 2.jpg</div>   <div id="img3">image 3.jpg</div> </span>  <script type="text/javascript">   function toggle_form_element(select) {     var divselect = select.value;     var elements = dropdown.getelementsbytagname("div");       (var = 0; < elements.length; i++) {         if (i == divselect) {           elements[i].style.display = "block";         } else {           elements[i].style.display = "none";         }       }   } </script>

any appreciated. thank you!

add styles

<style> #dropdown .image {     display: none; } </style>

then add class elements:

<div id="img1" class="image">image 1.jpg</div> <div id="img2" class="image">image 2.jpg</div> <div id="img3" class="image">image 3.jpg</div>

so, @ beginning images hidden css.

after making choice in select, js make 1 of them shown.

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
