I am having trouble comparing strings in this array. For some reason, the strings are never equal.
var person = ["Sam", "John", "Mary", "Liz"];
var searchedName = prompt("Enter name");
var resultMessage = "";
for (index in person) {
var currentName = person[index];
if (currentName === searchedName){
resultMessage = "Found Person";
} else {
resultMessage = "No match found!";
}
}
console.log(resultMessage);If you are looking to find a specific person in an array, you can utilize the Array#some method.
var people = ["Sam", "John", "Mary", "Liz"];
var firstName = prompt("Please enter a name");
var personFound = people.some(person => person === firstName);
var message = personFound ? "Person Found" : "No match found!";
console.log(message);
This code snippet essentially checks if at least one person in the 'people' array matches the input name provided by the user.
Try this out...
const people = ["Sam", "John", "Mary", "Liz"];
const inputName = prompt("Enter a name");
let outputMessage = "";
people.forEach((name) => {
if (inputName.toLowerCase() === name.toLowerCase()) {
outputMessage = "Person found";
return false;
} else {
outputMessage = "No match found!";
}
});
console.log(outputMessage);
This code has been tested and works properly.
I made some modifications to your code, hopefully it will now function as intended.
var individuals = ["Sam", "John", "Mary", "Liz"];
var userInput = prompt("Please enter a name");
var outputMessage = "";
for (name in individuals) {
// var firstName = individuals[name];
if (name.localeCompare(userInput)) {
outputMessage = "No match found!";
} else
{
outputMessage = "Person Found";
}
}
console.log(outputMessage);
var members = ["Jake", "Sarah", "Michael", "Emily"];
var searchName = prompt("Please enter a name:");
var result;
for (var i in members) {
console.log(searchName);
console.log(members[i]);
if (searchName === members[i]) {
result = "Found Member";
} else {
result = "Not Found";
}
console.log(result);
}
Here's a simple way to check if a specific string is present in an array:
console.log(members.includes(searchName)); // This returns true or false
Make sure to delete the line that reads var firstName = person[x];
View a working demonstration here
for (var x in person) {
// var firstName = person[x];
if (firstName == person[x])
{
message = "Person Found";
break;
}
else
{
message = "Not Found";
}
//console.log(firstName);
}
console.log(message);
