jquery - Displaying inputs based on previous selection -

-

i have page several select inputs take following form

<div class="row">     <div class="col-md-12">         <div class="form-group">             <div class="col-sm-7">                 <select class="selectpicker" name="producttype" id="producttype">                     <option value=""></option>                     <option value="cereal">cereal</option>                 </select>             </div>         </div>     </div> </div>

what trying display select inputs when previous select has been selected. doing

$( "#producttype" ).change(function() {    if($(this).val() != '') {        $('#yearrow').css('display', 'block');    } else {        $('#yearrow').css('display', 'none');    } });

i have set working jsfiddle

although have works, have feeling going ugly. reason because if select first input, , second, , unselect first, third input remain. handle display of every input within every select change function, think messy. basically, want avoid this

$( "#producttype" ).change(function() {    if($(this).val() != '') {        $('#yearrow').css('display', 'block');    } else {        $('#yearrow').css('display', 'none');        $('#monthrow').css('display', 'none');        $('#idrow').css('display', 'none');        //any other rows    } });

is there better way of doing attempting do?

thanks

you can try this:

  • add class selects , row parents.

then can use select's class selector this:

$( ".selectpicker" ).change(function() {     var $this = $(this);      //display next select     if ($this.val().tostring().length) {         $this.closest('div.select-parent').next('div.select-parent').removeclass('hiddenrow');         return;     }      //hide next selects     $this.closest('div.select-parent').nextall('div.select-parent').addclass('hiddenrow')        .find('select').val("").selectpicker('refresh'); //refresh select });

here fiddle.
