在div中显示响应

Question

我目前在警告中显示resp。

如何在我的span中显示class错误？

代码：

if(resp == '')
        {

        }else{
            alert(resp);
        }
    },

Answer 1

if(resp == '')
        {

        }else{
                                //!!!! set your response --                                     
           $("span.error").html(resp);
//here select span ^^^^ with class error
        }
    },

Answer 2

if(resp != null && resp != ''){
    var span = document.createElement('span ');
    span .className = 'error';
    span .innerHTML = resp ;
    document.getElementById('parentDivId').appendChild(span);

}

Answer 3

试试这段代码

if(resp == '')
{//some code.
}else{
    $(".error").text(resp);
}

Answer 4

if(resp == '')
        {
           // Do whatever your want
        }else{
            $('.errorspan').text(resp);
        }
    }
