json到嵌套的无序列表 [英] json to nested unordered list

问题描述

我正在尝试将JSON转换为jQuery中的无序列表.这是我的JSON数据.

I am trying to convert a JSON into an unordered list in jQuery.This is my JSON data.

var myJSON = "{name:\"Director\",children:[name:\"Exe Director1\",name:\"Exe Director2\",name:\"Exe Director3\",children:[name:\"Sub Director1\",name:\"Sub Director2\",name:\"Sub Director3\",children:[name:\"Cameraman 1\",name:\"Cameraman 2\"]]]}";

预期输出为

<ul>
    <li>Director
        <ul>
            <li>Exe Director 1</li>
            <li>Exe Director 2</li>
            <li>Exe Director 3
                <ul>
                    <li>Sub Director 1</li>
                    <li>Sub Director 2</li>
                    <li>Sub Director 3
                        <ul>
                            <li>Cameraman 1</li>
                            <li>Cameraman 2</li>
                        </ul>
                    </li>
                </ul>
            </li>
        </ul>
    </li>
</ul>

我该怎么办！

干杯

推荐答案

这正是您所需要的:

使用jQuery模板API.它曾经是jQuery的一部分，但目前仅可作为插件使用.但是，我认为jQuery将很快再次采用这种技术或类似技术.

Use the jQuery template API. This was once part of jQuery but is currently only available as plugin. However, I think jQuery will adopt this or a similar technique again soon.

http://api.jquery.com/category/plugins/templates/

它超级好用:

$.tmpl("template", jsonObject)

这是一个小的基本模板示例:

Here a small basic template example:

$.tmpl(
    "<li><b>${Id}</b>${Name}</li>", 
    [{Id:1, Name:"Werner"}, {Id:2, Name:"Klaus"}]
);

这将导致以下jQuery HTML元素可以附加到任何地方:

1 Werner

2 克劳斯

This will result in the following jQuery HTML element that can be appended to anywhere:

1 Werner

2 Klaus

对于复杂数据，您还可以使用"{{each}}"模板表示法来迭代JSON子对象.这里是您的数据和模板的代码:

For your complex data, you can also iterate JSON sub objects using the "{{each}}" template notation. Here the code for your data and template:

var data = {name:"Director",children:[{name:"Exe Director1"},{name:"Exe Director2"},{name:"Exe Director3", children:[{name:"Sub Director3_1"},{name:"Sub Director3_2"},{name:"Sub Director3_3",children:[{name:"Cameraman3_3_1"},{name:"Cameraman3_3_2"}]}]}]};

var template = '\
    <ul>\
        <li>${name}\
            <ul>\
                {{each(childindex, child) children}}\
                    <li>${child.name}\
                        <ul>\
                            {{each(child2index, child2) child.children}}\
                                <li>${child2.name}</li>\
                            {{/each}}\
                        </ul>\
                    </li>\
                {{/each}}\
            </ul>\
        </li>\
    </ul>\
';

$('body').empty().append($.tmpl(template, data));

浏览器结果:

• 导演
  • Exe Director1

    Browsers Result:

    • Director
      • Exe Director1

        • Sub Director3_1
        • Sub Director3_2
        • Sub Director3_3
        • ...

        可以通过包括嵌套模板来对它进行调整以支持完整的递归...但是我是个懒惰的人，其余的都是您要做的.

        This can be tweaked to support full recursion by including nested templates... but im a lazy guy and the rest is todo for you.
