Jquery Match Value to Array

Question

I have a navigation bar and divs that I want to show when their nav bar link is clicked on. Instead of having the divs be the descendants of the nav bar links, they are separate (I know this probably shouldn't be done). So, I created a data label for each nav bar link that matches the data label of the div that should be shown on click.

So, I want to click the nav link, find the data label (which I've done successfully with Jquery), match that data label against the different divs and display that div (while hiding the others). I think I need to create an array of the divs, then have some Jquery code to create an array and go through it to find the matching data type, then show that div...thanks for your help!

  <div id="nav">
  <ul>
    <li><a href="#" class="navselection" data-type="1">1</a></li>
    <li><a href="#" class="navselection" data-type="2">2</a></li>
    <li><a href="#" class="navselection" data-type="3">3</a></li>
    <li><a href="#" class="navselection" data-type="4">4</a></li>
    <li><a href="#" class="navselection" data-type="5">5</a></li>
  </ul>
</div>

<div id="main">
  <div id="main1" data-type="1">Main 1</div>
  <div id="main2" data-type="2">Main 2</div>
  <div id="main3" data-type="3">Main 3</div>
  <div id="main4" data-type="4">Main 4</div>
  <div id="main5" data-type="5">Main 5</div>
</div>

Pretty simple, hide all the divs on click, then show the one you want:

$("#nav ul li").click(function() {
    $("#main div").hide(); //hide others if open
    var type = $("a", this).data("type"); //get the data-type value of the clicked li's a child tag
    $("#main div[data-type='" + type + "']").show(); //show the matching data-type div 
});

This is great. Thank you for this simple solution. I was over-thinking it.

Why don't you use a tabgroup for the navigation, it'll display at the top of your page and once you click on different tabs it'll display each div. you can configure each div differently and wouldn't have to worry about them displaying on a page together.

Documentation: https://jqueryui.com/tabs/

Example of a basic tab interface provided by jqueryui.com :

<!doctype html>

<link rel="stylesheet" href="/resources/demos/style.css">
<script>
$(function() {
$( "#tabs" ).tabs();
});
</script>
</head>
<body>
<div id="tabs">

Below you can find code that solves your issue with several performance enhancements (see details inline in comments to the code).

var divs = $('#main [data-type]').hide(); // search divs one time instead of traversing DOM each time link is clicked

$('#nav').on('click', '.navselection', function() { // Bind one event listener to #nav with scope selector instead of having event listener on each link
  var type = this.getAttribute('data-type'); // minimize calls of slow DOM APIs by caching relevant data-type
  $.each(divs, function(index, div) { // iterate array only once and apply relevant function
    $(div)[div.getAttribute('data-type') === type ? 'show' : 'hide']();
  });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="nav">
  <ul>
    <li><a href="#" class="navselection" data-type="1">1</a></li>
    <li><a href="#" class="navselection" data-type="2">2</a></li>
    <li><a href="#" class="navselection" data-type="3">3</a></li>
    <li><a href="#" class="navselection" data-type="4">4</a></li>
    <li><a href="#" class="navselection" data-type="5">5</a></li>
  </ul>
</div>

<div id="main">
  <div id="main1" data-type="1">Main 1</div>
  <div id="main2" data-type="2">Main 2</div>
  <div id="main3" data-type="3">Main 3</div>
  <div id="main4" data-type="4">Main 4</div>
  <div id="main5" data-type="5">Main 5</div>
</div>

Also there is a solution without JavaScript at all (using CSS only)

#main > div {
  display: none;
}
#main > div:target {
  display: block;
}

<div id="nav">
  <ul>
    <li><a href="#main1" class="navselection">1</a></li>
    <li><a href="#main2" class="navselection">2</a></li>
    <li><a href="#main3" class="navselection">3</a></li>
    <li><a href="#main4" class="navselection">4</a></li>
    <li><a href="#main5" class="navselection">5</a></li>
  </ul>
</div>

<div id="main">
  <div id="main1">Main 1</div>
  <div id="main2">Main 2</div>
  <div id="main3">Main 3</div>
  <div id="main4">Main 4</div>
  <div id="main5">Main 5</div>
</div>
