Question

我的字符串如下所示。但是当通过javascript / jQuery将其转换为JSON时，会收到错误＆＃34; Invalid Charater＆＃34;。请帮忙

'[{ color: "#8B0000",  data: [{ "y":  12000,  "x":  0}],  pointRange: 8,  type: "column",  name: "Segment1"}, { color: "#FFA500",  data: [{ "y":  11000,  "x":  10}],  pointRange: 12,  type: "column",  name: "Segment2"}, { color: "#11ddbb",  data: [{ "y":  10000,  "x":  19}],  pointRange: 6,  type: "column",  name: "Segment3"}, { color: "#8B0000",  data: [{ "y":  8000,  "x":  24}],  pointRange: 5,  type: "column",  name: "Segment4"}]'

这是我用来将其解析为JSON的代码。

var response ='[{ color: "#8B0000",  data: [{ "y":  12000,  "x":  0}],  pointRange: 8,  type: "column",  name: "Segment1"}, { color: "#FFA500",  data: [{ "y":  11000,  "x":  10}],  pointRange: 12,  type: "column",  name: "Segment2"}, { color: "#11ddbb",  data: [{ "y":  10000,  "x":  19}],  pointRange: 6,  type: "column",  name: "Segment3"}, { color: "#8B0000",  data: [{ "y":  8000,  "x":  24}],  pointRange: 5,  type: "column",  name: "Segment4"}]';
response=$.parseJSON(response);
alert(response);

Answer 1

原始的响应消息是无效的json。

选项1：

你拥有的是一个Javascript对象（如果你删除那些单引号）。你没有JSON字符串而是Javascript对象。

从开头删除引号后，它看起来像

var response = [{ color: "#8B0000",  data: [{ "y":  12000,  "x":  0}],  pointRange: 8,  type: "column",  name: "Segment1"}, { color: "#FFA500",  data: [{ "y":  11000,  "x":  10}],  pointRange: 12,  type: "column",  name: "Segment2"}, { color: "#11ddbb",  data: [{ "y":  10000,  "x":  19}],  pointRange: 6,  type: "column",  name: "Segment3"}, { color: "#8B0000",  data: [{ "y":  8000,  "x":  24}],  pointRange: 5,  type: "column",  name: "Segment4"}];

var jsonString = JSON.stringify(response);

您现在可以选择使用JSON.stringify()将其转换为JSON字符串。

您还有一个选项2：

为所有键值添加双引号，这也是有效的。这将使它成为一个JSON字符串。然后，您可以使用JSON.parse()将其转换为JSON对象。

var response = '[{ "color": "#8B0000", "data": [{ "y":12000, "x":0}], "pointRange": 8, "type": "column", "name": "Segment1"}, { "color": "#FFA500", "data": [{ "y": 11000, "x": 10}], "pointRange": 12, "type": "column", "name": "Segment2"}, { "color": "#11ddbb", "data": [{ "y": 10000, "x": 19}], "pointRange": 6, "type": "column", "name": "Segment3"}, { "color": "#8B0000", "data": [{ "y": 8000, "x": 24}], "pointRange": 5, "type": "column", "name": "Segment4"}]';

var jsonObject = JSON.parse(response);

Answer 2

如果您有时间，请访问http://www.json.org/。在那里你会发现JSON的规范。

你的一个问题是：对象中的键必须是双引号中的字符串。

例如： '{ color: "#8B0000" }'错了

必须是： '{ "color": "#8B0000" }'

Answer 3

以下可能是解决方案

var response ='[{ color: "#8B0000",  data: [{ "y":  12000,  "x":  0}],  pointRange: 8,  type: "column",  name: "Segment1"}, { color: "#FFA500",  data: [{ "y":  11000,  "x":  10}],  pointRange: 12,  type: "column",  name: "Segment2"}, { color: "#11ddbb",  data: [{ "y":  10000,  "x":  19}],  pointRange: 6,  type: "column",  name: "Segment3"}, { color: "#8B0000",  data: [{ "y":  8000,  "x":  24}],  pointRange: 5,  type: "column",  name: "Segment4"}]';
var Obj=eval(response);
var response=JSON.stringify(Obj);
alert(response);

Answer 4

在Javascript json字符串中将所有键转换为带引号的字符串，如颜色到“颜色”等。 < / p>

var response = '[{ "color": "#8B0000",  "data": { "y":  12000,  "x":  0},  "pointRange": 8,  "type": "column",  "name": "Segment1"}, { "color": "#FFA500",  "data": [{ "y":  11000,  "x":  10}],  "pointRange": 12,  "type": "column",  "name": "Segment2"}, { "color": "#11ddbb",  "data": [{ "y":  10000,  "x":  19}],  "pointRange": 6,  "type": "column",  "name": "Segment3"}, { "color": "#8B0000",  "data": [{ "y":  8000,  "x":  24}],  "pointRange": 5,  "type": "column",  "name": "Segment4"}]';
response=JSON.parse(response);
console.log(response);

Answer 5

@Monsta - 你在密钥中缺少双引号;代码应该是这样的：

var response ='[{ "color": "#8B0000",  "data": [{ "y":12000,  "x":0}],  "pointRange": 8,  "type": "column",  "name": "Segment1"}, { "color": "#FFA500",  "data": [{ "y":  11000,  "x":  10}],  "pointRange": 12,  "type": "column",  "name": "Segment2"}, { "color": "#11ddbb",  "data": [{ "y":  10000,  "x":  19}],  "pointRange": 6,  "type": "column",  "name": "Segment3"}, { "color": "#8B0000",  "data": [{ "y":  8000,  "x":  24}],  "pointRange": 5,  "type": "column",  "name": "Segment4"}]';
JSON.parse(response);

通过javascript或JQUERY将字符串解析为JSON？
