我试图根据单选按钮选择在复选框输入上自动选择一些，我能够做到这一点，但是对于我的清单我正在使用检查树插件，当我尝试读取输入元素时它没有采取...... .:(
下面是我的代码，
<script>
$(function() {
$('.check-all').live('change', function(){
$('.options').find('input[class=def]').attr('checked', true);
return false;
});
$('.uncheck-all').live('change', function(){
$('.options').find('input[class=def]').attr('checked', false);
return false;
});
});
</script>
<script type="text/javascript">
var $checktree;
$(function(){
$checktree = $("ul.tree").checkTree();
});
</script>
<div id="main">
<div class="full_w" >
<div class="b2"><b>Define categories </b></div></div>
<div id="cat_left">
<div class="content">
</div>
<form action="http://localhost:8080/cgi-bin/cat_checkbox.pl" method="POST" name="form1">
<div class="options">
<ul>
<label><input type="radio" name="Selection" class="check-all" value="Default" id="type_0" checked="checked" />Default</label>
<label><input type="radio" name="Selection" class="uncheck-all" value="Custom" id="type_1" />Custom</label>
</ul>
<ul>
<li><input type="checkbox" class="def"id="option1" /><label for="option1">Option 1</label></li>
<li><input type="checkbox" class="def" id="option2" /><label for="option2">Option 2</label></li>
<li><input type="checkbox" class="def" id="option3" /><label for="option3">Option 3</label></li>
<li><input type="checkbox" class="def" id="option4" /><label for="option4">Option 4</label></li>
<li><input type="checkbox" id="option5" /><label for="option5">Option 5</label></li>
</ul>
// I tried till here its working fine, not able to do this same stuff foe below input elements
