Question

在我的控制器中我有：

  def rate
    @konkurrencer = Rating.where(:IP => @ip, :konkurrencer_id => params[:id])
    if @konkurrencer.empty?
    render :nothing => true
    else
    render :status => 500, :text => "This server hosted at sadasa"
    end
   end
end

我的ajax电话：

 jQuery.ajax({
             url: frm.attr('action'), //your server side script
             data: frm.serialize(), //our data
             type: 'POST',
             success: function (data) {
            $('.warning').fadeIn(500).css({display: 'block',
                position: 'absolute',
                left: position.left + 50,
                top: position.top - 25
            }).html('Du har stemt').fadeOut(1000),
            $(ri).next('.ratingcount').html('asdasdasd')
            },
             error: function (msg) {
                 alert(msg); //something went wrong.
             }
         });

问题是警告中显示的消息是[object Object]而不是文字This server hosted at sadasa

Answer 1

这可能主要是因为jQuery ajax的错误函数可能有3个参数：error(jqXHR, textStatus, errorThrown)。第一个是XMLHttpRequest对象。查看更多：http://api.jquery.com/jQuery.ajax/

<强>解决方案尝试将您的错误功能替换为：

error: function (responseObject) {
    alert(responseObject.responseText); //something went wrong.
}

希望有所帮助！

Answer 2

将alert(msg)更改为alert(msg.responseText)

Rails ajax错误调用文本未显示
