bootstrap-treeview.js自定义addNode和deleteChildrenNode方法

1，Tree主函数return添加以下代码；

// add and delete Children Node
addNode : $.proxy(this.addNode, this),
deleteChildrenNode : $.proxy(this.deleteChildrenNode, this),

2，添加Tree的prototype方法

/**
 * 给节点添加子节点
 * 
 * @param {Object|Number}
 *            identifiers - A valid node, node id or array of node
 *            identifiers
 * @param {optional
 *            Object} options.node;
 */
Tree.prototype.addNode = function(identifiers, options) {

    this.forEachIdentifier(identifiers, options, $.proxy(
            function(node, options) {
                this.setAddNode(node, options);
            }, this));
    this.nodes = [];//重置nodes为空，避免重复数据添加。
    this.setInitialStates({
        nodes : this.tree
    }, 0);
    this.render();
}

/**
 * 添加子节点
 */
Tree.prototype.setAddNode = function(node, options) {
    if (node.nodes == null)
        node.nodes = [];
    if (options.node) {
        node.nodes.push(options.node);
    }
    ;
};

/**
 * 删除子节点 置空子节点 刷新节点
 * 
 * @param node
 * @param options
 */
Tree.prototype.deleteChildrenNode = function(identifiers, options) {
    this.forEachIdentifier(identifiers, options, $.proxy(
            function(node, options) {
                if (node.nodes != null) {
                    node.nodes = null;
                    this.setInitialStates({
                        nodes : this.tree
                    }, 0);
                    this.render();
                }
            }, this));
};
