检查数组Javascript中是否存在一组值

Question

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");
             }                            
      })

UPDATE

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

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

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

Answer 1

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

data.Branchname.includes(locate)

EDIT

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

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

Answer 2

You just need to reverse the includes() as it is array.includes(value)

 tabledata.DataTable.forEach(function (data) { var locate = data.Location; var branch = data.BranchName; //if branch is string you need to do like this /* var branch = data.BranchName.split(','); */ if (branch.includes(locate)) { alert("Success"); } else { alert("failure"); } })
