我正在尝试找出将某些JSON数据转换为bootstrap-treeview请求的格式的最佳方法。我最初的想法是创建某种递归函数来完成并修改所有内容,但我在实现这一点时遇到了一些真正的困难。任何建议将不胜感激!
这是我的服务返回的数据的控制台日志:
Object

London: Object
Bayerische Staatsbibliothek: Object
Cod. arab. 1251: Array[1]

这是boostrap-treeview需要的格式:
var tree = [
{
text: "Parent 1",
nodes: [
{
text: "Child 1",
nodes: [
{
text: "Grandchild 1"
},
{
text: "Grandchild 2"
}
]
},
{
text: "Child 2"
}
]
},
{
text: "Parent 2"
},
{
text: "Parent 3"
},
{
text: "Parent 4"
},
{
text: "Parent 5"
}
];
这是我尝试使用递归函数来完成此任务:
function format_for_treeview(node) {
for (var key in node) {
// skip loop if the property is from prototype
if (!node.hasOwnProperty(key)) continue;
if (typeof node === 'object') {
format_for_treeview(node[key]);
if (Array.isArray(node)) {
node[key]['text'] = node[key]['bibliography_text'];
} else {
node[key]['text'] = key;
}
}
}
}

在following link的帮助下,我发现d3的nest()函数几乎完全符合我的需要。但是,我确实必须分叉d3.js文件并重命名'键'和#'价值观' nest()中的键名 - > entries()映射函数。
此外,我修改了服务以返回对象数组,而不是尝试在服务中进行分组。
var withText = jsondata.map(function(i) {
i['text'] = i['bibliography_text'];
return i;
});
var nestedData = d3.nest()
.key(function(d) { return d.country; })
.key(function(d) { return d.city; })
.entries(withText);
结果输出给出了一个与上面列出的var tree = [...]
完全相同的数组。

如果您需要bootstrap treeview
并希望将任意JSON
数据解析为其格式。您可以使用此递归function
。我刚刚对原始代码进行了一些更改。
function format_for_treeview(node) {
for (var key in node) {
// skip loop if the property is from prototype
if (!node.hasOwnProperty(key)) continue;
if (typeof node === 'object') {
format_for_treeview(node[key]);
if (Array.isArray(node)) {
node[key]['text'] = node[key]['bibliography_text'];
} else {
node[key]['text'] = key;
}
}
}
}
更改此功能会像您预期的那样工作。 (请参阅下面的代码段。)
function format_for_treeview(data, arr) {
for (var key in data) {
if(Array.isArray(data[key]) || data[key].toString() === "[object Object]") {
// when data[key] is an array or object
var nodes = [];
var completedNodes = completeNodes(data[key], nodes);
arr.push({ text: key, nodes: completedNodes });
} else {
// when data[key] is just strings or integer values
arr.push({ text: key + " : " + data[key] });
}
}
return arr;
}
var data = {
"title": "Person",
"type": "object",
"properties": {
"firstName": {
"type": "string"
},
"lastName": {
"type": "string"
},
"age": {
"description": "Age in years",
"type": "integer",
"minimum": 0
}
},
"required": ["firstName", "lastName"]
};
$(document).ready(function() {
function format_for_treeview(data, arr) {
for (var key in data) {
if (Array.isArray(data[key]) || data[key].toString() === "[object Object]") {
// when data[key] is an array or object
var nodes = [];
var completedNodes = format_for_treeview(data[key], nodes);
arr.push({
text: key,
nodes: completedNodes
});
} else {
// when data[key] is just strings or integer values
arr.push({
text: key + " : " + data[key]
});
}
}
return arr;
}
$("#my-treeview").treeview({
color: "#428bca",
expandIcon: "glyphicon glyphicon-stop",
collapseIcon: "glyphicon glyphicon-unchecked",
showTags: true,
data: format_for_treeview(data, [])
});
});
<link href="https://jonmiles.github.io/bootstrap-treeview/bower_components/bootstrap/dist/css/bootstrap.css" rel="stylesheet" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script src="https://jonmiles.github.io/bootstrap-treeview/js/bootstrap-treeview.js"></script>
<div id="my-treeview"></div>
您可以自定义push
部分,通过在它们之间插入HTML字符串使“key:value”更加显着。如下所示。
arr.push({ text: "<span class="key-stub"> + key + "</span>", nodes: completedNodes });
就个人而言,如果您只需要一个将JSON
转换为树视图的功能,那么您就不必为此而烦恼。只需考虑使用this one.无需转换。
