Change the content of a div based on selection from dropdown menu

Question

Is there a simple way  using JavaScript  to dynamically show hide content in a  lt div gt  based on the users selection from a drop down menu  For example  if a user selects option 1 then I would like  lt div gt  1 to be displayed and all other  lt div gt s to be hidden   EDIT  Example HTML Setup   lt select gt   lt option gt  Option 1 lt  option gt   lt option gt  Option 2 lt  option gt   lt option gt  Option 3 lt  option gt   lt select gt    lt div id  content 1  style  display hidden   gt Content 1 lt div gt   lt div id  content 2  style  display hidden   gt Content 2 lt div gt   lt div id  content 3  style  display hidden   gt Content 3 lt div gt

The accepted answer has a couple of shortcomings    Don t target IDs in your JavaScript code  Use classes and data attributes to avoid repeating your code  It is good practice to hide with CSS on load rather than with JavaScript mdash to support non-JavaScript users  and prevent a show-hide flicker on load    Considering the above  your options could even have different values  but toggle the same class    lt select class  div-toggle  data-target   my-info-1  gt     lt option value  orange  data-show   citrus  gt Orange lt  option gt     lt option value  lemon  data-show   citrus  gt Lemon lt  option gt     lt option value  apple  data-show   pome  gt Apple lt  option gt     lt option value  pear  data-show   pome  gt Pear lt  option gt   lt  select gt    lt div class  my-info-1  gt     lt div class  citrus hide  gt Citrus is    lt  div gt     lt div class  pome hide  gt A pome is    lt  div gt   lt  div gt    jQuery     document  on  change     div-toggle   function       var target     this  data  target      var show      option selected   this  data  show        target  children   addClass  hide        show  removeClass  hide          document  ready function            div-toggle   trigger  change          CSS    hide     display  none      Here s a JSFiddle to see it in action

There are many ways to perform your task  but the most elegant are  I believe  using css  Here are basic steps   Listening option selection event  biding adding removing some class to container action  which contains all divs you are interested in  for example  body  Adding styles for hiding all divs except one   Well done  sir     This works pretty well if there a few divs  since more elements you want to toggle  more css rules should be written  Here is more general solution  binding action  base on following steps    1  find all elements using some selector  usually it looks like   menu-container  menu-item     2  find one of found elements  which is current visible  hide it   3  make visible another element  the one you desire to be visible under new circumstances   javascript it a rather timtoady language
