修改tree数组的键值（name改成myname）

var tree = {
    name: "root",
    children: [{
        name: "child1",
        children: [{
            name: "child1_1",
            children: [{
                name: "child1_1_1",
                children: []
            }]
        }]
    }, {
        name: "child2",
        children: [{
            name: "child2_1",
            children: []
        }]
    }, {
        name: "child3",
        children: []
    }]
};

function traverseTree(node) {
    var child = node.children,
        arr = [];
    arr.push({ myname: node.name, children: child });
    if (child) {
        child = child.forEach(function (tmp, index, arrr) {
            arrr[index] = traverseTree(arrr[index]);
        });
    }
    return arr;
}
var ss = traverseTree(tree);
console.log(ss);
