我的部分功能未执行，我知道代码很可怕，我试图使其更高效。
Chrome开发者控制台错误：
未捕获的RangeError：超出最大调用堆栈大小
我已尝试评论要完成的工作。我希望这有帮助。
我正在从网站上抓取数据（大量数据，大约6000个请求）。
该脚本需要从中获取信息，然后确定比赛是否结束，如果没有完成，它只是将比赛信息记录到我的数据库中，然后继续。
如果比赛没有结束，我需要通过ajax从我的域中获取用户ID，然后将信息保存到数据库中，然后移至下一条记录。
我不得不使用自定义循环，因为ajax搞砸了排序。
这是我的代码，如果您需要更好的解释，请告诉我
function getTournamentInfo(){
/**
* We need to create a loop that fires AJAX only after the first request
* has finished so the results don't get out of order and screwed up.
* Evaluate if the current tournamentid is greater than the ending id
**/

// with the funciton and get the tournament

最佳答案
您正在使用没有返回语句的递归函数（getTournamentInfo）。
那么发生了什么：
getTournamentInfo（）在永不中断的循环中调用getTournamentInfo（），直到Javascript解释器崩溃并引发“超出最大调用堆栈大小”错误为止。
