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 c Solution 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')); } } Copy with html: <select id="ExtraField_1" name="ExtraField_1" onchange="javascript: onSelect(this);" > <option value="0">Select a test..</option> <option value="1">test1</option> <option value="2">test2</option> <option value="3">test3</option> <option value="4">test4</option> <option value="5">test5</option> <option value="6">test6</option> <option value="7">test7</option> <option value="8">test8</option> <option value="9">test9</option> <option value="10">test10</option> <option value="11">test11</option> <option value="12">test12</option> </select> <select id="ExtraField_2" name="ExtraField_2"> <option value="0">Select from the left</option> </select>​ Copy as 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 Firefox Webextension: How Do I Run Code Prior To Disable/uninstall?
