Use strict equality operators ( === ) to compare two strings in JavaScript if the condition. The “regular” == operator can have very unexpected results due to the type-coercion internally, so using === is always the recommended approach.
if (string1 === string2) {
console.log("Matching strings!");
}if (title === "LastName")
doSomething();Compare two strings in JavaScript if the condition
Simple example code.
<!DOCTYPE html>
<html>
<body>
<script>
var string1 = "Hello World";
var string2 = "Hello world.";
if (string1 === string2) {
console.log("Matching strings!");
}
else {
console.log("Strings do not match");
}
</script>
</body>
</html> Output:
it is possible that there is a whitespace to the left and or right of one string. So, just put a .trim() at the end of strings before comparing:
if(s1.trim() === s2.trim())
{
// your code
