Bootstrap treeview增加或者删除节点

参考（AddNode： http://blog.csdn.net/qq_25628235/article/details/51719917，deleteNode：http://blog.csdn.net/u012718733/article/details/53288584）

Bootstrap treeview增加或者删除节点

功能说明：展开节点时，新增子节点。选中节点时，删除节点

第一步：在bootstrap-treeview.js文件中，在Tree主函数return {/*在这里添加addNode的入口*/ 和 {/*在这里添加deleteNode的入口*/}

 //添加节点
            addNode: $.proxy(this.addNode, this),
            //删除节点
            deleteNode: $.proxy(this.deleteNode, this),
            setDeleteNode: $.proxy(this.setDeleteNode, this),

第二步：添加Tree的prototype方法

Tree.prototype.addNode = function(identifiers, options) {
        this.forEachIdentifier(identifiers,options,
            $.proxy(function(node, options) {
                    this.setAddNode(node, options);
                },
                this));

        this.setInitialStates({ nodes: this.tree }, 0);
        this.render();
    }

    Tree.prototype.setAddNode = function(node, options) {
        if (node.nodes == null) node.nodes = [];
        if (options.node) {
            node.nodes.push(options.node);
        };
    };

    Tree.prototype.deleteNode = function (identifiers, options) {
        this.forEachIdentifier(identifiers, options, $.proxy(function (node, options) {
            var parentNode = this.getParent(node);
            this.setDeleteNode(parentNode, node, options);
        }, this));
    };

    Tree.prototype.setDeleteNode = function (node, deletenode, options) {
        if (node.nodes != null) {
            for (var i = node.nodes.length - 1; i >= 0; i--) {
                var mynode = node.nodes[i];
                if (mynode.id === deletenode.id) {
                    node.nodes.splice(i, 1);
                }
            }
            this.setInitialStates({ nodes: this.tree }, 0);
            this.render();
        }
    };

第三步 调用

<div id="tree1"></div>

Json数据

  function getTree() {
             var data = [
                 {
                     text: "p1",
                     id: '0',
                     nodes: [
                         { text: "p1-1", id: '1' },
                         { text: "p1-2", id: '2' },
                         { text: "p1-3", id: '3' },
                         {
                             text: "p1-4",
                             id: '4',
                             nodes: [
                                 {
                                     text: 'p1-1-1',
                                     id: '5'
                                 }
                             ]
                         }
                     ]
                 }
             ];
             return data;
         }

绑定Treeview

 $("#tree1")
                         .treeview({
                             data: getTree(),
                             showIcon: false,
                             showCheckbox: true,
                             onhoverColor: "#E8E8E8",
                             showBorder: false,
                             showTags: true,
                             highlightSelected: true,
                             highlightSearchResults: false,
                             selectedBackColor: "#8D9CAA",
                             levels: 2,
                             onNodeSelected: function(event, data) {
                                 alert(data.nodeId);
                                 if (data.nodes === undefined || data.nodes === null) {
                                     return;
                                 }
                                 $("#tree1").treeview("deleteNode", [data.nodeId, { silent: true }]);
                                 //nodeData是checkedNode或者selectedNode，选中或者checked这个节点， 该节点如果有父节点的话就会被删除。
                             },
                             onNodeExpanded:
                                 function(event, data) {
                                         $.ajax({
                                             type: "Post",
                                             url: "/Bootstrap/GetExpandJson?id=" + data.id,
                                             dataType: "json",
                                             success: function (result) {
                                                 for (var index = 0; index < result.length; index++) {
                                                     var item = result[index];
                                                     $("#tree1")
                                                         .treeview("addNode",
                                                         [
                                                             data.nodeId,
                                                             { node: { text: item.text, id: item.id }, silent: true }
                                                         ]);
                                                 }
                                             }
                                         });
                                 }
                         });
