检查数组Javascript中是否存在一组值 [英] Check if a group of values exist in array Javascript

问题描述

我有一个像这样的表，其中有一些location值.如果此位置值包含除"California" "New york" ,"HQ" , "Florida"以外的任何其他值，则应显示警告消息，例如location无效. 我已经尝试过以下代码.

I have a table like this in which i have some values for location . If this location values contains any other values except "California" "New york" ,"HQ" , "Florida" it should show alert message like location is not valid . I have tried following code .

   tabledata.DataTable.forEach(function (data) {
       var locate = data.Location;
     if (locate.includes(data.BranchName)) {
       alert("Success");
      } else {
     alert("failure");
             }                            
      })

更新

branchDetails.forEach(function (data) {
       console.log(data.BranchName);
  });

此处data.BranchName包含"California" "New york" ,"HQ" , "Florida"，而locate包含表位置值.

here data.BranchName contains "California" "New york" ,"HQ" , "Florida" and locate contains the table location value .

我的问题是，即使表包含"HQ"，它也显示为失败

My issue here is even though the table contains "HQ" it is showing as failure

推荐答案

我认为您刚刚使用的方法有误.尝试使用:

I think you just used includes the wrong way. Try using:

data.Branchname.includes(locate)

编辑

您还可以安全地检查情况数据.分支名称未定义

You could also safe check in case data.Branchname is undefined

data.Branchname && data.Branchname.includes(locate)
