如何在HTML中实现“全选”复选框?

我有一个带有多个复选框的HTML页面。

我需要一个名称为“全选”的复选框。当我选择此复选框时，HTML页面中的所有复选框都必须被选中。我该怎么做呢?

    function checkAll(obj1) {
        var checkboxCollection = document.getElementById('<%=CheckBoxList1.ClientID %>').getElementsByTagName('input');

        for (var i = 0; i < checkboxCollection.length; i++) {
            if (checkboxCollection[i].type.toString().toLowerCase() == "checkbox") {
                checkboxCollection[i].checked = obj1.checked;
            }
        }
    }
</script>

使用jQuery制作的简写版本

全选复选框

<input type="checkbox" id="chkSelectAll">

children复选框

<input type="checkbox" class="chkDel">
<input type="checkbox" class="chkDel">
<input type="checkbox" class="chkDel">

jQuery

$("#chkSelectAll").on('click', function(){
     this.checked ? $(".chkDel").prop("checked",true) : $(".chkDel").prop("checked",false);  
})

试试这个简单的JQuery:

$('#select-all').click(function(event) {
  if (this.checked) {
    $(':checkbox').prop('checked', true);
  } else {
    $(':checkbox').prop('checked', false);
  }
});

<script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js" /></script>

<script type="text/javascript">
$(document).ready(function(){

$('input[name="all"],input[name="title"]').bind('click', function(){
var status = $(this).is(':checked');
$('input[type="checkbox"]', $(this).parent('li')).attr('checked', status);
});

});
</script>




<div id="wrapper">
 <li style="margin-top: 20px">
  <input type="checkbox" name="all" id="all" /> <label for='all'>All</label>
  <ul>
   <li><input type="checkbox" name="title" id="title_1" /> <label for="title_1"><strong>Title 01</strong></label>
