jQuery UI：如何在drop事件中从数组中获取数据

Question

假设我有一个数组

<script>

    sectionsP = {
        "test": {
            "sections": {
                "1": {
                    "name": "test1",
                    "html": "<div id='test1-id'>Test 1 Hello</div>"
                }
                "2": {
                    "name": "test2",
                    "html": "<div id='test2-id'>Test 2 Hello</div>"
                }
            }
        }

        "dummy": {
            "sections": {
                "1": {
                    "name": "dummy1"
                    "html": "<div id='dummy1-id'>Dummy 1 Hello</div>" 
                }
                "2": {
                    "name": "dummy2"
                    "html": "<div id='dummy2-id'>Dummy 2 Hello</div>" 
                }
            }
        }
    }

</script>

我想知道如何在drop事件上增加数据。例如，如果我有拖放测试2，那么我想要测试的数组 - ＆gt;部分 - ＆gt;以html格式删除的2个值。
