在div中显示响应

Question

我目前有resp显示在警报中。

如何在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

试试这个代码

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

Answer 4

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