Question

以下是我的控制器，它返回String

@RequestMapping("/hello1")  
    public @ResponseBody  
        String hello1() {  
           String jsonString = "[{\"deviceId\": \"  e71b0be12218393e121cb728595af68995889fb9\",\"deviceName\": \"  Xcaliber?s iPad3\",\"serialNumber\": \"  DMPH9E74DJ8R\",\"modelNumber\": \"  MC706\",\"productType\":\"  iPad3,1\",\"deviceClass\": \"  iPad\"},{\"deviceId\": \"\", \"deviceName\": \"\",\"serialNumber\": \"\",\"modelNumber\": \"\",\"productType\": \"\",\"deviceClass\": \"\"}]";
return jsonString;
}

我在javascript中将此字符串作为响应。我正在尝试使用javascript中的代码

var deviceJsonDetails = $.parseJSON(response);
         for(var count = 0;count < response.length; count++){
                             var id = count+1;
                             alert(deviceJsonDetails[count].deviceId);
                             $("#deviceId"+id).html(deviceJsonDetails[count].deviceId);
                             $("#deviceName"+id).html(deviceJsonDetails[count].deviceName);
                             $("#serialNumber"+id).html(deviceJsonDetails[count].serialNumber);
                             $("#modelNumber"+id).html(deviceJsonDetails[count].modelNumber);
    }

但它在var deviceJsonDetails = $.parseJSON(response);上出错了错误：SyntaxError：JSON.parse：期望的属性名称或'}'

你能否告诉我在js中解析相同字符串的错误或替代解决方案在哪里？

检查http://jsonlint.com/

中的JSON字符串

您需要解析的正确字符串应为：删除“\”

[
    {
        "deviceId": "e71b0be12218393e121cb728595af68995889fb9",
        "deviceName": "Xcaliber?siPad3",
        "serialNumber": "DMPH9E74DJ8R",
        "modelNumber": "MC706",
        "productType": "iPad3,1",
        "deviceClass": "iPad"
    },
    {
        "deviceId": "",
        "deviceName": "",
        "serialNumber": "",
        "modelNumber": "",
        "productType": "",
        "deviceClass": ""
    }
]

无法在javascript中解析json String，这是java方法的响应
