Hello,

i have eleven drop down lists, one of them is main, and from the ten other lists only one should be visible. What i am doing is when i choose one option from the main select box, one of the ten other boxes becomes visible depending on which i choose, i tried onclick in the option tag but it didn't work, i tried onchange in the select tag also doesn't work.

Here is the code i have:

<script type="text/javascript">
        /*<![CDATA[*/
        function searchList()
{
if(this.options[this.selectedIndex].value=='-1') Disconnect();
if(this.options[this.selectedIndex].value=='1') B1();
if(this.options[this.selectedIndex].value=='2') C1();
if(this.options[this.selectedIndex].value=='3') E1();
if(this.options[this.selectedIndex].value=='4') G1();
if(this.options[this.selectedIndex].value=='5') I1();
if(this.options[this.selectedIndex].value=='6') J1();
if(this.options[this.selectedIndex].value=='7') M1();
if(this.options[this.selectedIndex].value=='8') O1();
if(this.options[this.selectedIndex].value=='9') S1();
if(this.options[this.selectedIndex].value=='10') S2();
};

AboJaD,

The solution can be quite concise.

Delete the entire script (sorry) and paste in this:

onload = function(){
	var menus = ['Closed', 'S_B1', 'S_C1', 'S_E1', 'S_G1', 'S_I1', 'S_J1', 'S_M1', 'S_O1', 'S_S1', 'S_S2'];//list of secondary menu ids
	for(var i=0; i<menus.length; i++) {
		menus[i] = document.getElementById(menus[i]);//translate ids into DOM elements
	}
	var groups = document.getElementById('groups');
	if(groups){
		groups.onchange = function(){
			var val = Number(this.options[this.selectedIndex].value);//read value and cast it as a Number.
			for(var i=0; i<menus.length; i++) {
				if(menus[i]) {
					menus[i].style.display = ((val===i) ? 'block' : 'none');// hide all secondary menus except the menu of interest.
					menus[i].selectedIndex = 0;// (optional) reinitialise menu in case it was previously selected by the user.
				}
			}
		};
	}
};

You also need to make changes to the groups menu:

<select id="groups" name="groups">
       <option value="0">Select Category:</option>
       <option value="1">Business</option>
       <option value="2">Common Interest</option>
       <option value="3">Entertainment & Arts</option>
       <option value="4">Georgraphy</option>
       <option value="5">Internet & Technology</option>
       <option value="6">Just for Fun</option>
       <option value="7">Music</option>
       <option value="8">Organizations</option>
       <option value="9">Sports & Recreaction</option>
       <option value="10">Student Groups</option>
</select>

NOTES:

  • Added id="groups"
  • onchange="....." is removed. The function is now attached by the script.
  • The value of the first option is changed from -1 to 0. This allows the javascript simpler.
  • The options' ids are purged as they appeared to be unnecessary. But you can put them back if you need them for some other purpose.
