javascript - 未捕获的类型错误 : Cannot set property 'nodeId' of undefined

Question

在为我的 boostrap-treeview 检索 JSON 数据时，我在 boostrap-treeview.js:267 上收到此错误。

$(document).ready(function() {
    $.ajax({ 
        url: "js/category_data.php",
        method:"POST",
        dataType: "json",            
        success: function(data) {
            $('#doctypesTree').treeview({ data: data });
        }    
    });
});

JSON数据如下:

{

            "id":"12",
            "text":"Certified copy",

我正在使用 Bootstrap Tree View

任何想法

您的 json 是一个对象。您必须将其转换为数组才能使树工作。您可以更改 php 以返回正确的数组，也可以使用 javascript 将其转换为数组，如下所示。

var data = {
  "2": {
    "id": "12",
    "text": "Certified copy",
    "Description": "",
    "root": "0"
  },
  "3": {
    "id": "13",
    "text": "Charter",
    "Description": "",
    "root": "0"
  },
  "4": {
    "id": "14",
    "text": "Codicil (will)",
    "Description": "",
    "root": "0"
  },
  "5": {
    "id": "15",
    "text": "Cohabitation agreement",
    "Description": "",
    "root": "0"
  },
  "6": {
    "id": "16",
    "text": "Collateral assurance",
    "Description": "",
    "root": "0"
  },
  "7": {
    "id": "17",
    "text": "Commercial invoice",
    "Description": "",
    "root": "0"
  },
  "8": {
    "id": "18",
    "text": "Complaint",
    "Description": "",
    "root": "0"
  },
  "9": {
    "id": "19",
    "text": "Conservation easement",
    "Description": "",
    "root": "0"
  },
  "10": {
    "id": "20",
    "text": "Consignee",

  "11": {

  },
  "12": {
    "id": "22",
    "text": "Contract",
    "Description": "",
    "root": "0"
  },
  "13": {
    "id": "23",
    "text": "Contractual term",
    "Description": "",
    "root": "0"
  },
  "14": {
    "id": "24",
    "text": "Contractual terms in English law",
    "Description": "",
    "root": "0"
  },
  "15": {
    "id": "25",
    "text": "Florence Annie Conybeare",
    "Description": "",
    "root": "0"
  },
  "16": {
    "id": "26",
    "text": "Copyright transfer agreement",
    "Description": "",
    "root": "0"
  },
  "17": {
    "id": "27",
    "text": "Countersign (legal)",
    "Description": "",
    "root": "0"
  },
  "18": {
    "id": "28",
    "text": "County Court judgment",
    "Description": "",
    "root": "0"
  },
  "19": {
    "id": "29",
    "text": "Credit Support Annex",
    "Description": "",
    "root": "0"
  },
  "20": {
    "id": "30",
    "text": "Customs declaration",
    "Description": "",
    "root": "0"
  },
  "21": {
    "id": "31",
    "text": "Bills",
    "Description": "",
    "root": "0",
    "nodes": [{
      "id": "4",
      "text": "Bill of costs",
      "Description": "This type gather all documents related to costs",
      "root": "31"
    }, {
      "id": "5",
      "text": "Bill of sale",
      "Description": "",
      "root": "31"
    }]
  }
};

var dataArray = [];
for (var key in data) {
    if (data.hasOwnProperty(key)) {
        dataArray.push(data[key]);
    }
};

$('#tree').treeview({data: dataArray});
