访问 Yahoo YQL 财务查询

Question

我在尝试使用 yql 语句时收到错误消息。控制台显示存在语法错误，但我没有看到错误。我已经发布了所有代码，因此可以复制并粘贴以重复错误。

Answer 1

我发现了我遇到的错误。现在这是正确的行：

var data = encodeURIComponent("select * from yahoo.finance.historicaldata where symbol = '" + symbol + "' and startDate = '" + dateInput + "' and endDate = '" + dateInput + "'");
