截图:

代码如下:
<script type="text/javascript">
    //三层规则点击逻辑
    //点击第一层规则时.第二层和第三层规则全部选中
    function checkname($obj,$pid) {
        var checked = $obj.checked;
        if (checked) {
            $('[pid= ' + $pid + ']').attr('checked', true);
        } else {
            $('[pid= ' + $pid + ']').attr('checked', false);
        }
    }
 
    //点击第二层规则时.第三层规则全部选中
    function check($obj, $id, $pid) {
        var checked = $obj.checked;
        if (checked) {
            $('.check' + $id).attr('checked', true);
        } else {
            $('.check' + $id).attr('checked', false);
        }
 
        //只要有一个单选框选中.则它的上一层就勾选
        home($pid);
    }
 
    //点击第三层规则时.第二层和第一层都勾选
    function checkChild($obj, $id, $pid) {
        var checkedLength = $(".check" + $id + ':checked').length;
        if (checkedLength > 0) {
            $('#check' + $id).attr('checked', true);
        } else {
            $('#check' + $id).attr('checked', false);
        }
        home($pid);
    }
 
    //父一级规则勾选
    function home($pid) {
        var checkedIdLength = $("[pid=" + $pid + "]:checked").length;
        if (checkedIdLength > 0) {
            $("#" + $pid).attr('checked', true);
        } else {
            $("#" + $pid).attr('checked', false);
        }
    }
