Hide/show The Selected Option On A Secondary Select

I have two elements with different IDs. When the user selects a value from the first select box, I want the second select box to only display connected values. My cSolution 1: If you can use jQuery then you can always just clear and append the options to the second select. $('#ExtraField_1').change(function(){ $('#ExtraField_2').find('option').remove() if($(this).val() == '1'){ $('#ExtraField_2').append($("<option </option>").attr('value','2').text('test2')); $('#ExtraField_2').append($("<option></option>").attr('value','3').text('test3')); $('#ExtraField_2').append($("<option></option>").attr('value','4').text('test4')); } if($(this).val() == '2'){ $('#ExtraField_2').append($("<option></option>").attr('value','5').text('test5')); $('#ExtraField_2').append($("<option></option>").attr('value','6').text('test6')); $('#ExtraField_2').append($("<option></option>").attr('value','7').text('test7')); } }); Copy​http://jsfiddle.net/8XVuv/2/using only javascript is a bit more complicated but I would still take the same approach.function createOption(otext,oValue){ var newOption = document.createElement('option'); newOption.text = otext; newOption.value = oValue; return newOption; } function clearSelect(theSelect){ for(var i = 0;i <= theSelect.options.length+1;i++) { theSelect.remove(); } } function onSelect(theSelect){ var nextSelect = document.getElementById('ExtraField_2'); clearSelect(nextSelect); var selected = theSelect.options[theSelect.selectedIndex]; if(selected.value == 1){ nextSelect.add(createOption('test2','2')); nextSelect.add(createOption('test3','3')); nextSelect.add(createOption('test4','4')); } if(selected.value == 2){ nextSelect.add(createOption('test5','5')); nextSelect.add(createOption('test6','6')); nextSelect.add(createOption('test7','7')); } } Copywith html:<selectid="ExtraField_1"name="ExtraField_1"onchange="javascript: onSelect(this);" ><optionvalue="0">Select a test..</option><optionvalue="1">test1</option><optionvalue="2">test2</option><optionvalue="3">test3</option><optionvalue="4">test4</option><optionvalue="5">test5</option><optionvalue="6">test6</option><optionvalue="7">test7</option><optionvalue="8">test8</option><optionvalue="9">test9</option><optionvalue="10">test10</option><optionvalue="11">test11</option><optionvalue="12">test12</option></select><selectid="ExtraField_2"name="ExtraField_2"><optionvalue="0">Select from the left</option></select>​ Copyas you can see it still does what you expect but you are not hiding options. http://jsfiddle.net/upKzW/13/Solution 2: $('#ExtraField_1').change(function() { $('#ExtraField_2').val(this.value); Copy});http://jsfiddle.net/judearasu/rF8G6/ Share Post a Comment for "Hide/show The Selected Option On A Secondary Select" Top Question How Do I Use The Deezer Api?
