一套前端设计语言和基于React的实现

export function getNodeChildren(options, value) {
    if (options && options.length > 0) {
        var currOptions = options.find(function (it) { return it.value === value; });
        if (currOptions && Array.isArray(currOptions.children)) {
            return currOptions.children;
        }
    }
    return null;
}
export function getNodeKey(node) {
    var n = node;
    var values = [];
    while (n) {
        values.unshift(n.value);
        n = n.parent;
    }
    return values.map(function (s, i) { return i + "$" + s; }).join('@');
}
export function getNodeDepth(node) {
    var depth = 1;
    var parent = node.parent;
    while (parent) {
        parent = parent.parent;
        depth++;
    }
    return depth;
}
