用数学方法将时间字符串解析为数字可能更为优雅，例如： 常数timeStringToValue=timeStr=>{ 常数[，小时，分钟，安培]=timeStr.match/\d+：\d+[ap]m/； 常数ampmHourModifier=ampm=='pm'？12:0； 返回次数小时+安培小时修改器+分钟/60 }; 控制台：logtimeStringToValue'10:00AM'；
控制台：logtimeStringToValue'3:30 pm'；嘿，谢谢，我实际上是在尝试给时间赋值，因为最后我希望能够计算出这个值，所以我做了一个切换案例，给它们赋值。你知道如何使用这些值吗？不清楚你在寻找什么额外的功能-在答案中，timeStr是动态的，任何东西都可以使用需要解析的任何时间字符串调用timeStringToValue，一个下拉菜单将有时间，它将引用一个值，这些值将被计算得到总小时数。如果这有助于将从timeStringToValue检索到的所有值相加..？谢谢，抱歉，我只是在多次发布之前不理解您的答案，但是调用函数的愚蠢问题是它是console.logtimeStringToValueconst finishMonTimeStr=$'。完成时间星期一选项：selected'。text；我不是技术人员哈哈
