空手道框架-为什么Javascript函数返回具有NaN值的数组? [英] Karate Framework - Why Javascript function returns an array with NaN values?

问题描述

我在空手道场景中编写了javascript函数，该函数将参数中的当前日期作为参数，并获取日期，年份，月份并将它们添加到数组中.但是由于某些未知原因，我得到了NaN值.请在下面查看我一直在使用的空手道步骤.

I wrote javascript function in Karate scenario and the function takes in current date in argument and gets date, year, month and adds them in a array. But for some unknown reason I get NaN values. Please see below karate steps that I have been using.

    * def dateArr2 = []
    * def dateParse =
        """
            function(myOrderDate)
            {
              dateArr2.add(myOrderDate); // this is for test purpose

              var today = new Date(myOrderDate);
              var dd = today.getDate();     
              var mm = today.getMonth()+1; //January is 0!
              var yyyy = today.getFullYear();
              dateArr2.add(yyyy);
              dateArr2.add(mm);
              dateArr2.add(dd);               
            }
        """ 
   * def ongoingDateTime = "2018-10-19T11:53:39.8795965Z"
   * eval dateParse(ongoingDateTime)     

请注意，如果我在js执行环境(例如sublime-text)中执行，类似的javascript代码对我有用.

Note, the similar javascript code works for me if I am executing in js execution environment such as sublime-text.

推荐答案

请保持简单并使用Java.文档中有示例: https://github.com/intuit/karate#java-interop

Just keep it simple and use Java please. There are examples in the doc: https://github.com/intuit/karate#java-interop

如果太麻烦了，请编写Java实用程序.

If it is too troubling, write Java utilities.

* def toDate =
    """
    function(s) {
      var SimpleDateFormat = Java.type('java.text.SimpleDateFormat');
      var sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS");
      return sdf.parse(s)           
    }
    """ 
* def raw = "2018-10-19T11:53:39.8795965Z"
* def date = toDate(raw)
* print date.day, date.month, date.year

只需查看java.util.Date的API，您现在就拥有了所有这些功能.

Just look at the API for java.util.Date and you have all of that now.
