Question

有SymbologyObject和ValuesArray：

var SymbologyObject = {};
var ValuesArray = [];

将一些东西放入其中，如下所示：

var ValueOfField = "tree";
ValuesArray[ValueOfField] = [];

var localStyle = {};
localStyle.fill = "#ffff";
localStyle.stroke = "#cccc";
localStyle.width = 3;
localStyle.value = ValueOfField;

ValuesArray[ValueOfField] = localStyle;

SymbologyObject.type = "Unique";
SymbologyObject.label = "test";

SymbologyObject.attr = "attribute";

SymbologyObject.values = ValuesArray;

当我使用console.log(SymbologyObject);输出时：

attr:"attribute"
label:"test"
type:"Unique"
values:
tree:{fill: "#ffff", stroke: "#cccc", width: "3", value: "tree"}

我将它转换为json：

JSON.stringify(SymbologyObject);

上述代码的输出：

{"type":"Unique","label":"test","attr":"attribute","values":[]}

但我想要低于输出：

{"type":"Unique","label":"test","attr":"attribute","values":[tree:{"fill": "#ffff", "stroke": "#cccc", "width": "3", "value": "tree"}]}

有什么问题？

Answer 1

首先，你的变量初始化是错误的你必须像下面这样初始化。

var SymbologyObject = {};
var ValuesArray = {}; //<< CHANGE

其次，请参阅下面的更改。

var ValueOfField = "tree";
ValuesArray[ValueOfField] = {}; //<<CHANGE

var localStyle = {};
localStyle.fill = "#ffff";
localStyle.stroke = "#cccc";
localStyle.width = 3;
localStyle.value = ValueOfField;

ValuesArray[ValueOfField] = localStyle;

SymbologyObject.type = "Unique";
SymbologyObject.label = "test";

SymbologyObject.attr = "attribute";

SymbologyObject.values = ValuesArray;

所以，输出将如下所示。

{"type":"Unique","label":"test","attr":"attribute","values":{"tree1":{"fill":"#ffff","stroke":"#cccc","width":3,"value":"tree1"},"tree":{"fill":"#ffff","stroke":"#cccc","width":3,"value":"tree"}}}

Answer 2

首先检查您的JSON，因为它不是有效的JSOn。 `

{
    "type": "Unique",
    "label": "test",
    "attr": "attribute",
    "values": [tree: {
        "fill": "#ffff",
        "stroke": "#cccc",
        "width": "3",
        "value": "tree"
    }]
}
