Jquery树形控件 $.fn.zTree.init(, setting, r.treeList)

zTree的配置
zTree的配置采用Json格式，按照配置的类型分为view（可视界面相关配置）、data（数据相关配置）、check（复选框相关配置）、callback（各类事件的回调函数配置）、async（zTree异步加载配置）

var setting = {
    data: {

            rootPId: -1
        },
        key: {

        },

    },
    callback: {
        onClick: zTreeOnClick
    }
