无法在对象中找到函数包含

Question

当我调用下面列出的代码时，我收到以下错误。

Cannot find function contains in object Is Patient Fasting?/# of Hours->Yes; 12 hours.

我的代码：

    var i = 0;

    var tempFastingQuest = "";
    var tempFastingAns = msg['OBR']['OBR.39'].toString();

    while (msg['NTE'][i] != null) {

           tempFastingQuest = msg['NTE'][i]['NTE.3']['NTE.3.1'].toString();

           if (tempFastingQuest.contains("Yes"))
                  tempFastingAns =  "Y";

           i = i + 1
    }

我在这里缺少什么？

假设这是JavaScript：字符串没有contains()方法，错误明确指出。也许您正在寻找search()方法：if (tempFastingQuest.search('Yes') > -1) ...
