The simplest way to do compare strings ignore case is to call toUpperCase method in JavaScript. We can call it case insensitive string comparison.
Just use === operator
str1.toUpperCase() === str2.toUpperCase()JavaScript compares strings ignore-case
Simple example code compares strings without being case sensitive.
<!DOCTYPE html>
<html>
<body>
<script>
var str1 = "aBc";
var str2 = "AbC";
if (str1.toUpperCase() === str2.toUpperCase())
{
console.log("Both string have same text")
}
</script>
</body>
</html> Output:
Or you can both string lowercase.
var string1 = "aBc";
var string2 = "AbC";
if (string1.toLowerCase() === string2.toLowerCase())
{
#stuff
