jquery - 当#div.load 出错时向div 添加一个类？(Jquery)

Question

当 div.load 出错时，我需要用 red 显示我的错误消息，如代码所示。如果成功，我会按原样呈现内容，我该怎么做？

$('#TermsAndConditions').load(termsconditionsurl, null, function (response, status, xhr) {
    if (status == "error") {
        var msg = "Sorry there was an error: ";
    $(this).addClass("error");

            $("#TermsAndConditions").html(msg + xhr.status + " " + xhr.statusText);


    }
});

谢谢，阿达什

假设根据您的选择器，div 的 ID 为“TermsAndConditions”，您可以这样做:

if (status == "error") 
{         
  var msg = "Sorry there was an error: ";     
  $(this).addClass("error")
} 

在 css 中有:

.error
{
  color: red;
}

编辑:

你应该把它放在文档就绪函数中:

$(document).ready(function() {
  var div = $("#TermsAndConditions");

  if (status == "error")
  {
   var msg = "sorry there was an error:";
   div.val(msg);
    div.addClass("error");
  }
});
