动态嵌套对象数组的递归迭代

如果我对您的理解正确，那么您希望每个“子代”都有一个

parentID

0

index

function normalize(parent) {    if (parent && parent.children) {        for (var i = 0, l = parent.children.length; i < l; ++i) { var child = parent.children[i]; child.index = i; if (!child.parentId) child.parentId = parent.id || '0'; normalize(child);        }    }}normalize(data);
