I suspect you're right... its probably something really stupid... Here's the specific html for the two listboxes (see below for the rest):
<fieldset> <legend>Step 4: Pick the distribution zone(s)</legend> <div class='div_left'> <label class='column' id='labavail_zones' for='ajavail_zones'>Available Zones</label><?php fill_pdzones(); ?> </div> <div class='div_center'> <input type='button' value=' >>' onclick="addAll()"><br> <input type='button' value=' > ' onclick="addAttribute()"><br> <input type='button' value=' < ' onclick="delAttribute()"><br> <input type='button' value='<< ' onclick="delAll()"> </div> <div class='div_right'> <label class='column' id='labdest_zones' for='selectedOptions'>Destination Zones</label> <select id='selectedOptions' name='selectedOptions' style="width:150px;" size="4" multiple="multiple"> <option value='whoohoo'>test</option> </select> </div> </fieldset> the first select is created and filled with this code: function fill_pdzones() { echo "<select id='availableOptions' name='availableOptions' style='width:150px;' size='4' multiple='multiple'>\n"; // boring stuff omitted $result = sql_query($query); while( $record = mysql_fetch_array($result, MYSQL_ASSOC ) ) { $zone_name = $record['zone_name']; echo "<option value='$zone_name'>$zone_name</option>\n"; } // close off this select echo "</select>\n"; } The javascript used to move items between list boxes is this: // JavaScript Document var selectedList; var availableList; function createListObjects(szSource, szDestination) { availableList = document.getElementById(szSource); selectedList = document.getElementById(szDestination); } function delAttribute(){ var selIndex = selectedList.selectedIndex; if(selIndex < 0) return; availableList.appendChild( selectedList.options.item(selIndex)) selectNone(selectedList,availableList); setSize(availableList,selectedList); } function addAttribute(){ var addIndex = availableList.selectedIndex; if(addIndex < 0) return; selectedList.appendChild( availableList.options.item(addIndex)); selectNone(selectedList,availableList); setSize(selectedList,availableList); } function setTop(top){ document.getElementById ('someLayer').style.top = top; } function setLayerTop(lyr,top){ lyr.style.top = top; } function setSize(list1,list2){ list1.size = getSize(list1); list2.size = getSize(list2); } function selectNone(list1,list2){ list1.selectedIndex = -1; list2.selectedIndex = -1; addIndex = -1; selIndex = -1; } function getSize(list){ /* Mozilla ignores whitespace, IE doesn't - count the elements in the list */ var len = list.childNodes.length; var nsLen = 0; //nodeType returns 1 for elements for(i=0; i<len; i++){ if(list.childNodes.item(i).nodeType==1) nsLen++; } if(nsLen<2) return 2; else return nsLen; } function delAll(){ var len = selectedList.length -1; for(i=len; i>=0; i--){ availableList.appendChild(selectedList.item(i)); } selectNone(selectedList,availableList); setSize(selectedList,availableList); } function addAll(){ var len = availableList.length -1; for(i=len; i>=0; i--) { selectedList.appendChild(availableList.item(i)); } selectNone(selectedList,availableList); setSize(selectedList,availableList); } function showSelected() { var optionList = document.getElementById("selectedOptions").options; var data = ''; var len = optionList.length; for(i=0; i<len; i++) { data += ','; data += optionList.item(i).value; } alert(data); } On Sat, Jul 2, 2011 at 6:29 PM, Walter Lee Davis <wa...@wdstudio.com> wrote: > > On Jul 2, 2011, at 6:09 PM, Phil Petree wrote: > > When making the following ajax call: >> new Ajax.Updater( 'result', url, {method: 'post', parameters: >> $('myform').serialize(), onSuccess: fill_in, onFailure: ajax_err, on0: >> ajax_err}); >> I was wondering why my listbox contents were not showing up on the >> server... stepping through the Ajax.Updater call in prototype I found >> parameters was set/serialized as follows: >> >> parameters "status=insert&record=&userid=**2&police=0&injury=0&damage=0&* >> *occured=07%2F02%2F2011&**message_text=woo%20hoo&** >> countdown=1017&lat=&lon=&**fixed=2020%20NE%2056th%20St.%** >> 2C%20Ft.%20Lauderdale%2C%20FL%**2033308" String >> >> At the end, where "String" is dangling like a participle, should be the >> name of a listbox and the single option in the listbox. >> >> Would someone kindly tell me what I have to do to get a listbox to >> serialize? >> >> Thanks! >> > > It should just do.
