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),
View Code

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();
        }
    };
View Code

第三步 调用

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

 Json数据

 1  function getTree() {
 2             var data = [
 3                 {
 4                     text: "p1",
 5                     id: '0',
 6                     nodes: [
 7                         { text: "p1-1", id: '1' },
 8                         { text: "p1-2", id: '2' },
 9                         { text: "p1-3", id: '3' },
10                         {
11                             text: "p1-4",
12                             id: '4',
13                             nodes: [
14                                 {
15                                     text: 'p1-1-1',
16                                     id: '5'
17                                 }
18                             ]
19                         }
20                     ]
21                 }
22             ];
23             return data;
24         }

 2                         .treeview({

10                             highlightSearchResults: false,
11                             selectedBackColor: "#8D9CAA",

15                                 if (data.nodes === undefined || data.nodes === null) {
16                                     return;

18                                 $("#tree1").treeview("deleteNode", [data.nodeId, { silent: true }]);
19                                 //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。
