问题描述

我正在寻找一种使用标题中提到的嵌套< div> 的JSON树。这里是一个数据样本(树中最多有8个层次):

  {
儿童:{
细菌:{
儿童:{
Verrucomicrobia:{
children:{
Methylacidiphilae:{
children:{
Methylacidiphilales:{
children:{},
count:2,
level:order,
name:Methylacidiphilales,
分数:1.46
}
},
count:2,
等级: class,
name:Methylacidiphilae,
分数:1.46
}
},
count:2,
level:phylum,
name:Verrucomicia,
score:1.46

$ count $ b $ level
$ level $ b $ name
$ b $分数:1.46
}
},
count:0,
level:root,
name:Root,
score:0.0
}

我可以得到/解析JSON树并保存到一个变量。现在我需要递归地遍历树:


  1. 使每个节点都可以呈现为HTML格式。

  2. 创建一个新的 div 节点并添加到新树中。

但是怎么样?

解决方案

b
$ b

 函数json2html(json){
var i,ret =;
ret + =< ul>;
for(i in json){
ret + =< li>+ i +:;
if(typeof json [i] ===object)ret + = json2html(json [i]);
else ret + = json [i];
ret + =< / li>;
}
ret + =< / ul>;
return ret;
}

只需使用您的对象调用该函数,它将返回HTML作为嵌套列表集合 - 当然,如果您愿意,您可以将其更改为仅使用< div> s。

编辑:这里是一个使用DOM元素的版本,并且返回一个可以用 appendChild 或类似符号插入的节点:

  function json2html(json){
var i,ret = document.createElement('ul'),li;
for(i in json){
li = ret.appendChild(document.createElement('li'));
li.appendChild(document.createTextNode(i +:));
if(typeof json [i] ===object)li.appendChild(json2html(json [i]));
else li.firstChild.nodeValue + = json [i];
}
return ret;
}


I am looking for a way to render a JSON tree using nested <div> as mentioned in the title. Here is a sample of the data (there is a max of 8 levels in the tree):

{
    "children": {
        "Bacteria": {
            "children":{
                "Verrucomicrobia":{
                    "children":{
                        "Methylacidiphilae":{
                            "children":{
                                "Methylacidiphilales":{
                                    "children":{},
                                    "count":2,
                                    "level":"order",
                                    "name":"Methylacidiphilales",
                                    "score":1.46
                                }
                            },
                            "count":2,
                            "level":"class",
                            "name":"Methylacidiphilae",
                            "score":1.46
                        }
                    },
                    "count":2,
                    "level":"phylum",
                    "name":"Verrucomicrobia",
                    "score":1.46
                }
            },
            "count":2,
            "level":"kingdom",
            "name":"Bacteria",
            "score":1.46
        }
    },
    "count":0,
    "level":"root",
    "name":"Root",
    "score":0.0
}

I can get/parse the JSON tree and save it to a variable. Now I need to traverse the tree recursively and either:

  1. Make each node into something that can be rendered as HTML.
  2. Create a new div node and add to a new tree.

But how?

解决方案

You could do this in raw JS with little to no difficulty:

function json2html(json) {
    var i, ret = "";
    ret += "<ul>";
    for( i in json) {
        ret += "<li>"+i+": ";
        if( typeof json[i] === "object") ret += json2html(json[i]);
        else ret += json[i];
        ret += "</li>";
    }
    ret += "</ul>";
    return ret;
}

Just call that function with your object, and it will return the HTML as a set of nested lists - you can of course change it to use just <div>s if you prefer.

EDIT: And here's a version that uses DOM elements and returns a node that can be inserted with appendChild or similar:

function json2html(json) {
    var i, ret = document.createElement('ul'), li;
    for( i in json) {
        li = ret.appendChild(document.createElement('li'));
        li.appendChild(document.createTextNode(i+": "));
        if( typeof json[i] === "object") li.appendChild(json2html(json[i]));
        else li.firstChild.nodeValue += json[i];
    }
    return ret;
}
