使用 jquery 选中或取消选中 parent parents 复选框

Question

当我选中 Account Settings 复选框时，所有子 li 输入标签都被完美选中。但是当我取消选中 Children li 复选框 Add 和 Delete 时，它也会取消选中 Account Settings。

我不想在选中 AS 1 和 AS 2 时取消选中 帐户设置。

帮帮我，如何解决这个问题。

试试这个

<ul class="tree" id="tree">
    <li>
        <input type="checkbox" name="account_settings" value="yes">Account Settings
        <ul>
            <li>
                <input class="account_settings" type="checkbox" name="one" value="one">AS One
            </li>
            <li>
                <input class="account_settings" type="checkbox" name="two" value="two">AS Two
            </li>
            <li>
                <input class="account_settings" type="checkbox" name="user_roles" value="user_roles">Users &amp; Roles
                <ul>
                    <li>
                        <input class="account_settings user_roles" type="checkbox" name="user_role" value="add">Add
                    </li>
                    <li>
                        <input class="account_settings user_roles" type="checkbox" name="user_role" value="delete">Delete
                    </li>
                </ul>
            </li>
        </ul>
    </li>
</ul>

$('input[type=checkbox]').click(function () {
    if($(this).prop('checked'))
    {
        $('.'+$(this).attr('name')).prop('checked',true);
    }
    else
    {
        $('.'+$(this).attr('name')).prop('checked',false);
    }
    findparent(this);
});
});

function findparent(elem)
{
    var flag = 1;
    var fcount = 0;
    var count = 0;
    $(elem).parent().parent().find('li input').each( function ( index ) {
        fcount = fcount +1;
        if($(this).prop('checked') == false)
            count = count + 1;
    });

    if(count == fcount)
        flag = 0;

    if(flag == 0)
        $(elem).parent().parent().prev().prop('checked',false);
    else
        $(elem).parent().parent().prev().prop('checked',true);
}
