var json = {

            "id": "1", "name": "1", "data": "0,3048", "children": [{ "id": "11", "name": "11", "data": "0,3048", "children": [{ "id": "111", "name": "111", "data": "0,3048", "children": [] }, { "id": "112", "name": "112", "data": "0,3048", "children": [{ "id": "1121", "name": "1121", "data": "0,3048", "children": [] }, { "id": "1122", "name": "1122", "data": "0,3048", "children": []}]}] }, { "id": "12", "name": "12", "data": "0,3048", "children": [] }, { "id": "13", "name": "13", "data": "0,3048", "children": [{ "id": "131", "name": "131", "data": "0,3048", "children": [{ "id": "1311", "name": "1311", "data": "0,3048", "children": []}] }, { "id": "132", "name": "132", "data": "0,3048", "children": []}] }, { "id": "14", "name": "14", "data": "0,3048", "children": []}]
        };

如何使用 HiddenField 将这些数据提供给 json？我的假设是：

JSonID.Value = "{""id"":""1"",""name"":""1"",""data"":""0,3048"",""children"":[{""id"":""11"",""name"":""11"",""data"":""0,3048"",""children"":[{""id"":""111"",""name"":""111"",""data"":""0,3048"",""children"":[]},{""id"":""112"",""name"":""112"",""data"":""0,3048"",""children"":[{""id"":""1121"",""name"":""1121"",""data"":""0,3048"",""children"":[]},{""id"":""1122"",""name"":""1122"",""data"":""0,3048"",""children"":[]}]}]},{""id"":""12"",""name"":""12"",""data"":""0,3048"",""children"":[]},{""id"":""13"",""name"":""13"",""data"":""0,3048"",""children"":[{""id"":""131"",""name"":""131"",""data"":""0,3048"",""children"":[{""id"":""1311"",""name"":""1311"",""data"":""0,3048"",""children"":[]}]},{""id"":""132"",""name"":""132"",""data"":""0,3048"",""children"":[]}]},{""id"":""14"",""name"":""14"",""data"":""0,3048"",""children"":[]}]""}"

和var json = document.getElementById('JSonID').value;

它不起作用。（JSonId.value 是 VB 代码，所以我使用 " 作为转义字符。）

【解决方案1】：

var json = document.getElementById('JSonID').value;

将简单地将元素中保存的字符串分配给json 变量。您需要将其解析为对象：

var json = JSON.parse(document.getElementById('JSonID').value);

JSON.parse是现代浏览器中的原生方法，但如果需要支持旧的，可以使用json2.js

非常感谢。有用。接受时间结束后，我会接受这个答案。
@user14570 好的。如果您经常在 .Net 中处理 JSON，您可能需要查看 Json.net
是的，我是 json 的初学者。我会看看。谢谢
