{"0":[{"id":1,"fatherId":0,"typeName":"測試","typeIndex":0,"typeStatus":"1"}],

後臺將資料按照key-value的形式存入map，key值為父id，value為同一父id的Po組成的List中，傳入前臺，方便構建類別樹，其中data[0]為初始化的根，需要保證返回的資料按照層級的先後順序。

前臺處理：

前臺頁面新增一個 <ul role="tree" id="typeLiId0"></ul>容器，

執行以下js方法

function listTypeTree(id){
    doPost("/action/type/listTypeTree",{},function(objs){
        if(objs.success){
            var data = objs.data;
            if(null == data){
                showErrorMsg("","類別資訊失敗！");
                return;
            }
            var obj = $("#" + id + " > div");
            for (var item in data) {
                appendNodeToTree('typeLiId', data[item]);
            }
            bindEvent();
        }else{

        }
    });
}
 

function appendNodeToTree(id, data){
    for (var i = 0, l = data.length; i < l; i++) {
        $("#" + id + data[i].fatherId).append('<li data-content="'+data[i].id+'"><span><i class="icon-leaf"></i>'+data[i].typeName+'</span><ul id="typeLiId'+data[i].id+'"></ul></li>');
    }
}

 

/**從bootstrap-tree.js拷貝*/
function bindEvent(){
    $('.tree > ul').attr('role', 'tree').find('ul').attr('role', 'group');
    $('.tree').find('li:has(ul)').addClass('parent_li').attr('role', 'treeitem').find(' > span').attr('title', 'Collapse this branch').on('click', function (e) {
        var children = $(this).parent('li.parent_li').find(' > ul > li');
        if (children.is(':visible')) {
            children.hide('fast');
            $(this).attr('title', 'Expand this branch').find(' > i').addClass('icon-plus-sign').removeClass('icon-minus-sign');
        }
        else {
            children.show('fast');
            $(this).attr('title', 'Collapse this branch').find(' > i').addClass('icon-minus-sign').removeClass('icon-plus-sign');
        }
        e.stopPropagation();
    });
}
