How can I hide/show a div when a button is clicked?

I have a div that contains a register wizard, and I need hide/show this div when a button is clicked. How can I do this?

Below I show you the code.

Thanks :)

  <div id="wizard" class="swMain">
    <ul>
      <li><a href="#step-1">
            <label class="stepNumber">1</label>
        </a></li>
      <li><a href="#step-2">
            <label class="stepNumber">2</label>
        </a></li>
      <li><a href="#step-3">
            <label class="stepNumber">3</label>
         </a></li>
      <li><a href="#step-4">
            <label class="stepNumber">4</label>
        </a></li>
    </ul>
    <div id="step-1"> 
        <h2 class="StepTitle">Perfil</h2>
        <table cellspacing="3" cellpadding="3" align="center">
            <tr>
                  <td align="center" colspan="3">&nbsp;</td>
            </tr>        
            <tr>
                  <td align="right">Username :</td>
                  <td align="left">
                    <input type="text" id="username" name="username" value="" class="txtBox">
                  </td>
                  <td align="left"><span id="msg_username"></span>&nbsp;</td>
            </tr>
            <tr>
                  <td align="right">Password :</td>
                  <td align="left">
                    <input type="password" id="password" name="password" value="" class="txtBox">
                  </td>
                  <td align="left"><span id="msg_password"></span>&nbsp;</td>
            </tr>                                          
       </table>               
    </div>

Solution 1:

Use JQuery. You need to set-up a click event on your button which will toggle the visibility of your wizard div.

$('#btn').click(function() {
    $('#wizard').toggle();
});

Refer to the JQuery website for more information.

This can also be done without JQuery. Using only standard JavaScript:

<script type="text/javascript">
   function toggle_visibility(id) {
       var e = document.getElementById(id);
       if(e.style.display == 'block')
          e.style.display = 'none';
       else
          e.style.display = 'block';
   }
</script>

Then add onclick="toggle_visibility('id_of_element_to_toggle');" to the button that is used to show and hide the div.

Solution 2:

This works:

     function showhide(id) {
       	var e = document.getElementById(id);
       	e.style.display = (e.style.display == 'block') ? 'none' : 'block';
     }

    <!DOCTYPE html>
    <html>   
    <body>
    
    	<a href="javascript:showhide('uniquename')">
    		Click to show/hide.
    	</a>
    
    	<div id="uniquename" style="display:none;">
    		<p>Content goes here.</p>
    	</div>
    
    </body>
    </html>

Solution 3:

This can't be done with just HTML/CSS. You need to use javascript here. In jQuery it would be:

$('#button').click(function(e){
    e.preventDefault(); //to prevent standard click event
    $('#wizard').toggle();
});

Solution 4:

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Show and hide div with JavaScript</title>
<script>

    var button_beg = '<button id="button" onclick="showhide()">', button_end = '</button>';
    var show_button = 'Show', hide_button = 'Hide';
    function showhide() {
        var div = document.getElementById( "hide_show" );
        var showhide = document.getElementById( "showhide" );
        if ( div.style.display !== "none" ) {
            div.style.display = "none";
            button = show_button;
            showhide.innerHTML = button_beg + button + button_end;
        } else {
            div.style.display = "block";
            button = hide_button;
            showhide.innerHTML = button_beg + button + button_end;
        }
    }
    function setup_button( status ) {
        if ( status == 'show' ) {
            button = hide_button;
        } else {
            button = show_button;
        }
        var showhide = document.getElementById( "showhide" );
        showhide.innerHTML = button_beg + button + button_end;
    }
    window.onload = function () {
        setup_button( 'hide' );
        showhide(); // if setup_button is set to 'show' comment this line
    }
</script>
</head>
<body>
    <div id="showhide"></div>
    <div id="hide_show">
        <p>This div will be show and hide on button click</p>
    </div>
</body>
</html>

Solution 5:

The following solution is:

briefest. Somewhat similar to here. It's also minimal: The table in the DIV is orthogonal to your question.
fastest: getElementById is called once at the outset. This may or may not suit your purposes.
It uses pure JavaScript (i.e. without JQuery).
It uses a button. Your taste may vary.
extensible: it's ready to add more DIVs, sharing the code.

mydiv = document.getElementById("showmehideme");

function showhide(d) {
    d.style.display = (d.style.display !== "none") ? "none" : "block";
}

#mydiv { background-color: #ddd; }

<button id="button" onclick="showhide(mydiv)">Show/Hide</button>
<div id="showmehideme">
    This div will show and hide on button click.
</div>
