从 JSON 对象的内部深度获取信息

我有一个来自CrunchBase API的JSON对象，给了我一堆来自给定公司的信息。现在我正在尝试浏览 JSON 对象并创建他们的投资者列表。投资者可以分为三类，"company", "financial_org", or "person"。所有三种类型都将附加到同一列表中，finalInvestorList

该脚本运行没有错误，但仅生成第一轮上市的投资者列表。我已经记录了我认为可能有帮助的所有内容。日志位于同一行注释中。

基本上我的问题是它只循环一次，因此只添加了第一轮的投资者。任何帮助将不胜感激。如果您需要更多信息，请告诉我！

  var investorList = function(data, num) {
        var fundingRounds = data["funding_rounds"];
        var finalInvestorList = []
        console.log(fundingRounds.length) // 3

        for (i=0; i < fundingRounds.length; i++) {
            var investments = data["funding_rounds"][i]["investments"];
            console.log(data["funding_rounds"][1]["investments"]); //correctly logs the index 1 round for spling (2nd round)
            var round = data["funding_rounds"][i];
            console.log('round' + i); //only logs round0, never loops around for round1, round2
            for (i=0; i < investments.length; i++) {
                var angelObject = round["investments"][i]["person"];
                if (angelObject != null) {
                    console.log("angel fired"); //fires for "Mitch Blumenfeld"
                    var angel = angelObject["first_name"] + " " + angelObject["last_name"];
                    finalInvestorList[i] = angel;
                }
                var financialOrgObject = round["investments"][i]["financial_org"];
                if (financialOrgObject != null) {
                    console.log("financial_org fired"); //fires for "Bucknell Venture Plan Competition"
                    console.log(financialOrgObject['name']); //Bucknell VPC
                    var financialOrg = financialOrgObject["name"]
                    finalInvestorList[i] = financialOrg
                }
                var companyObject = round['investments'][i]["company"];
                if (companyObject != null) {
                    console.log('company fired'); //i haven't bothered with this yet.. just logging it so ill know if its firing
                }
            }
        }
        console.log(finalInvestorList); //["Bucknell Venture Plan Competition", "Mitch Blumenfeld"]
    }

数据表示的JSON对象如下我只用需要的一点缩短了它。JSON 响应数据中的对象由 data["funding_rounds"] 表示此数据是使用 Crunch API 检索的，可以在 http://api.crunchbase.com/v/1/company/spling.js 中找到完整形式
