问题描述
我想从服务器中获取一些数据并追加一个jQuery-Listview,这是行不通的。 测试Chrome控制台时出现此错误:
未捕获的SyntaxError:意外的令牌i
我用来消耗来自服务器的Json字符串的代码:
$.ajax({
url: 'http://domain/GetArknr'
})
.done(function(data) {
$.each(JSON.parse(data), function(idx, obj) {
$('#listview').append('<li id="' + obj.ARKNR + '"><a href="#">' + obj.ARKNR + '</a></li>');
})
$('#listview').listview('refresh');
alert(data)
})
.fail(function() {
alert("Failed to fetch data");
})
和JSON:
[ { "arknr" : "0582",
"id" : "0582"
},
{ "arknr" : "0590",
"id" : "0590"
},
{ "arknr" : "0599",
"id" : "0599"

"id" : "1049"
},
{ "arknr" : "1050",
"id" : "1050"
}
]
在服务器端,我正在使用Spring 4.1.2。
响应在Chrome中以'xhr'列出-我不知道如何将响应声明为application/json
,我尝试对处理请求/GetArknr
的方法使用几种不同的注释:
@RequestMapping(value = "/GetArknr")
public ModelAndView getArknr() {
HashMap <String, Object> model = new HashMap();
List <Map<String, Object>> data = dataProvider.getArkNr();
model.put("table", data);
return new ModelAndView("json/arknrListJson", model);
}

通常,在Spring REST服务中,您不需要视图,而是希望使用并将生成的类型指定为“ application / json”
@RequestMapping(value = "/GetArknr", produces = "application/json")
@ResponseBody
public List<Map<String, Object>> getArknr() {
HashMap <String, Object> model = new HashMap();
List <Map<String, Object>> data = dataProvider.getArkNr();
return data;
}
然后在ajax调用中,您可以执行以下操作:
$.ajax({
cache : false,
type : 'GET',
url: 'http://domain/GetArknr',
dataType : 'json',
success : function(data) {
if (data == null) {
//error handling
}
$.each(data['something'], function(idx, obj) {
$('#listview').append('<li id="' + obj.ARKNR + '"><a href="#">' + obj.ARKNR + '</a></li>');
})
}
}
您也可以在$ .ajax调用中使用此请求以请求正确的数据格式(将Accept标头设置为“ application / json”)

jQuery通过智能方式选择.ajax数据变量类型,很有可能您不需要将数据解析为json,因为它已经是一个JavaScript对象。 您能告诉我们在function(data){之后显示什么console.log(data)吗?
