如何检查嵌套数组是否包含值? [英] How can I check If a nested array contains a value?

问题描述

所以我有这个数组:

   var watchesArray = [
        {
          model: "FR 10", 
          image:"",
          url: "",
          price: 129.99,
          sports: ["Running", "Fitness"],
          touchScreen:false,
          GPS:false,
          heartRateMonitor:false,
          hrZoneTraining:false,
        },
    ];

    if(watchesArray[0].sports(contains a specific value or values){
      do something
    } else {
       dont do anything
    }

我要做的就是检查这款手表是否具有特定的运动，如果确实有，则将其放在if语句中，以便我可以对其进行处理.

And all I want to do is check whether this watch has a specific sport and if it does then put it in an if statement so that I can do something with it.

我该怎么做?谢谢

推荐答案

使用 Array.indexOf 像下面这样

Use Array.indexOf like bellow

if(watchesArray[0].sports.indexOf('Running') > -1){
    do somwthing
}

注意:-:如果父母不存在，则会抛出错误.

NOTE:- In case of if parents doesn't exist it'll throw error.
