Issue with if statement on my JavaScript code

Question

I am trying to create an if statement for this code to only allow records with experience level 1-3 to show but not sure how to do it? this is partial code if need more let me know.

var table = document.getElementById('blueteam');

        table.innerHTML = ""; //Clears table
    if(explevel < 4){
        for (var i = 0; i < firstnames.length; i += 1) {
            var row = table.insertRow(0);
            var cell = row.insertCell(0);
            cell.innerHTML = firstnames[i] + " " + lastnames[i] + " Exp:" + explevel[i];
        }
    }
    };

I think you need to display more of the source code "Relevant source" I have no idea where explevel is being defined or firstnames. — NewToJS

try if(+explevel[i] < 4){ the if should also be in the for loop — Downgoat

Try the following code:

var table = document.getElementById('blueteam');

    table.innerHTML = ""; //Clears table

    for (var i = 0; i < firstnames.length; i += 1) {
        if(explevel[i] >= 1 && explevel[i] <= 3){
            var row = table.insertRow(0);
            var cell = row.insertCell(0);
            cell.innerHTML = firstnames[i] + " " + lastnames[i] + " Exp:" + explevel[i];
        }
    }
};

You were calling if explevel < 4 but since explevel is a list (explevel[i]), you cannot do that. Instead, check each iteration of explevel.

You can use the logical AND (&&) operator: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Logical_Operators

var table = document.getElementById('blueteam');

table.innerHTML = ""; //Clears table
for (var i = 0; i < firstnames.length; i++) {    
    if((explevel[i] >= 1) && (explevel[i] <= 3)){
        var row = table.insertRow(0);
        var cell = row.insertCell(0);
        cell.innerHTML = firstnames[i] + " " + lastnames[i] + " Exp:" + explevel[i];
    }
}

var table = document.getElementById('blueteam');

    table.innerHTML = ""; //Clears table
    var count = records.length;
    var record;
    for (var i = 0; i < count; i++) {
        record = records[i];
        if (reecord.explevel < 4) {
            var row = table.insertRow(0);
            var cell = row.insertCell(0);
            cell.innerHTML = record.firstname + " " + record.lastname + " Exp:" + record.explevel;   
        }
    }

I modified the data. I am not sure of firstnames, lastnames and explevel. I hope those should be present inside the record.

Sample Data

var records = [{
    "firstname": "",
    "lastname": "",
    "explevel": ""
}];
