JavaScript Show/Hide as Filters to list of divs

问题

Looking to create Javascript that acts like a filter on a list of divs. For instance, here's the intended markup...

<a href="#" onclick="">Filter Item 1</a>
<a href="#" onclick="">Filter Item 2</a>
<a href="#" onclick="">Filter Item 3</a>
<a href="#" onclick="">Filter Item 4</a>
<a href="#" onclick="">Filter Item 5</a>

<div class="1">Item 1</div>
<div class="1">Item 1</div>
<div class="2">Item 2</div>
<div class="3">Item 3</div>
<div class="1">Item 1</div>
<div class="4">Item 4</div>
<div class="4">Item 4</div>
<div class="1">Item 1</div>
<div class="5">Item 5</div>

I want to be able to click on the link for Item 1, and show only Item 1 divs and hide all other divs, click the link of Item 2, and show only Item 2 divs and hide all other divs and so on. I've seen several similar scripts but nothing that seemingly turns divs matching the class on/off in this manner.

This can be done easily in Jquery, following should work for you, but you have to modify your html as following

<a href="#" class="link" id="1">Filter Item 1</a>
<a href="#" class="link" id="2">Filter Item 2</a>
<a href="#" class="link" id="3">Filter Item 3</a>
<a href="#" class="link" id="4">Filter Item 4</a>
<a href="#" class="link" id="5">Filter Item 5</a>

<div class="1">Item 1</div>
<div class="1">Item 1</div>
<div class="2">Item 2</div>
<div class="3">Item 3</div>
<div class="1">Item 1</div>
<div class="4">Item 4</div>
<div class="4">Item 4</div>
<div class="1">Item 1</div>
<div class="5">Item 5</div>

and javascript as follows

$(document).ready(function(){
 $(".link").click(function(e){
  $("." + e.currentTarget.id).toggle()
 }
});

You can use jQuery's toggle. below is simple example:

    $(document).ready(function() {
        $('#IDOfLink').click(function() {
            $('.class1').toggle("slow");//switch to show/hide when clicked
            //hide other div u wish
        });

        $('#anotherLinkID').click(function() {
            $('.class2').toggle("fast");//switch to show/hide when clicked
            //hide other div u wish
        });
        //...etc...
    });

Very simple solution:

<a href="#" onclick="$('DIV').hide(); $('DIV.1').show(); return false;">Filter Item 1</a>

This, ofcourse, will hide all the other div's on page, so you should give the all some other class or put inside another div. Then the code could be:

<a href="#" onclick="$('#filtered DIV').hide(); $('#filtered DIV.1').show(); return false;">Filter Item 1</a>

<div id="filtered">
    <div class="1"></div>
    ...
</div>

Set an ID for each link, then assign an onclick event. There you can filter out divs using the clicked link ID.

Something like this (http://jsfiddle.net/pJRek/1/)

Markup:

<a href="#" class="bound" id="group_1">Filter Item 1</a>
<a href="#" class="bound" id="group_2">Filter Item 2</a>
<a href="#" class="bound" id="group_3">Filter Item 3</a>
<a href="#" class="bound" id="group_4">Filter Item 4</a>
<a href="#" class="bound" id="group_5">Filter Item 5</a>

<div class="group_1">Item 1</div>
<div class="group_1">Item 1</div>
<div class="group_2">Item 2</div>
<div class="group_3">Item 3</div>
<div class="group_1">Item 1</div>
<div class="group_4">Item 4</div>
<div class="group_4">Item 4</div>
<div class="group_1">Item 1</div>
<div class="group_5">Item 5</div>

And script:

$(document).ready(function(){
    var links = $('.bound');
    var divs = $('div');
    links.click(function(event){
       divs.hide();
       divs.filter('.' + event.target.id).show();
    });
});

If you setup your HTML as:

<div id="controls">    
  <a href="#" id="1">Filter Item 1</a>
  <a href="#" id="2">Filter Item 2</a>
  <a href="#" id="3">Filter Item 3</a>
  <a href="#" id="4">Filter Item 4</a>
  <a href="#" id="5">Filter Item 5</a>
</div>
<div id="items">
  <div class="1">Item 1</div>
  <div class="1">Item 1</div>
  <div class="2">Item 2</div>
  <div class="3">Item 3</div>
  <div class="1">Item 1</div>
  <div class="4">Item 4</div>
  <div class="4">Item 4</div>
  <div class="1">Item 1</div>
  <div class="5">Item 5</div>
</div>

Then your jQuery code can be as simple as:

$(function(){
    $("#controls a").click(function() {
        $("#items").find("." + this.id).toggle();   
    });
  });

Of course, you will want to add a visual indication that a filter is toggled on and off. You may not want to associate the items with each link through id/classes, but instead use jQuery's data storage, depending on your needs.

A working example, tested in firefox, here: http://jsfiddle.net/mwolfetech/GetRV/

Edit: This solution is similar to Anto Binish Kaspar's, mainly differing only in how the html is modified. I think that the divs given are likely to be a good structure for your document anyway, and eliminates the need for extra classes for control. This is always a design decision--balancing div (for structural division) vs class (for, categories). Additionally, theres no need to extract the id from the event object as jQuery provides the this reference.

Give them all another class (for example item) and then make the click hide all item and show all of the selected value.
