选中复选框时，jQuery隐藏div，未选中时显示

Question

I am trying to hide div when user clicks on checkbox, and show it when user unchecks that checkbox. HTML:

<div id="autoUpdate" class="autoUpdate">
   content
</div>

jQuery:

<script>
$('#checkbox1').change(function(){
        if (this.checked) {
            $('#autoUpdate').fadeIn('slow');
        }
        else {
            $('#autoUpdate').fadeOut('slow');
        }                   
    });
</script>

I am having a hard time to get this working.

Answer 1

Make sure to use the ready event.

Code:

$(document).ready(function(){
    $('#checkbox1').change(function(){
        if(this.checked)
            $('#autoUpdate').fadeIn('slow');
        else
            $('#autoUpdate').fadeOut('slow');

    });
});

HTML

<input type="checkbox" id="cbxShowHide"/><label for="cbxShowHide">Show/Hide</label>
<div id="block">Some text here</div>

css

#block{display:none;background:#eef;padding:10px;text-align:center;}

javascript / jquery

$('#cbxShowHide').click(function(){
this.checked?$('#block').show(1000):$('#block').hide(1000); //time for show
});
