Question

任何人都可以帮我解决为什么这不起作用？当我通过浏览器提交URL时，我有一个返回以下JSON的URL：

我已经在JSONLint中验证了JSON，它报告一切都很好。但是，当我从下面的ajax调用中调用相同的URL时，它会错误地将jqXHR textStatus和errorThrown错误地称为“parsererror”和“SyntaxError：Unexpected token”。

Per this stackoverflow post，我在服务器端使用了application / json标头，但是parseJSON仍然失败。我得到的最后一个警告是“数据不为空”......然后什么都没有。它甚至不会触发try / catch警报。这是ajax电话：

$.ajax({
    url: strUrl,
    type: "GET",
    dataType: "json"
})
    .fail(function( jqXHR, textStatus, errorThrown){
        alert("error: "+textStatus+" : "+errorThrown);
    })
    .done(function(data) {
        alert("success");

        if( !data || data === ""){
            alert("Server returned bad or empty data");
            return false;
        }else
            alert("data not null");
        var json;
        try {
            json = $.parseJSON(data);
        } catch (ex) {
            alert("There was an error translating the report XML. "+ex);
            return false;
        }

        alert("json.Name: "+json.Name);
    });

Chrome会报告错误：“未捕获的TypeError：无法读取属性'名称'为null”尽管我在发布“数据非空”后立即执行了try / catch。

我遇到同样的问题。您只需删除dataType: 'json',。
