jQuery实现列表的全选功能

function DelAlert(data)
    {
        if(data == 'error')
        {
            alert("错误～");
        }
        else if(data == 'success')
        {
            alert("成功～");
            location.reload();
        }
    }
    //引入jquery，这里后台配合的是thinkphp
    $(function(){
        //每行的checkbox需要有check-value属性来存放当前行的id
        //选中全部，checkAll 为选中全部的checkbox的id selctone 为每一行checkbox的class
        $('#checkAll').selectall('selectone');
        //删除选中，deleteAll为删除全部按钮的id  selectone 为每一行checkbox的class 后台接收参数ids 格式如： 1,2,3
        var url = "Home/Role/delall'";
        $('#deleteAll').delselect('selectone',url,function(data){
            DelAlert(data);
        },function(){
            layer.msg("没有选中内容",2,0);
        });
    })
