Could you share the solution of substring methods from the input string using HTML+Javascript ?
<!DOCTYPE html>
<html>
<body>
<input type="text" value="test"></input>
<button onclick="myFunction()" id="testCode">Click</button>
<script>
function myFunction() {
document.getElementById("testCode");
var res = substring(0, 5).value;
document.write(res);}
</script>
</body>
</html>
Substring will return part of the string. Also, add the ID on input field to get the value but rather using the button id itself. See the following snippet
function myFunction() {
const test = document.getElementById("testInput");
var res = test.value.substr(0, 3);
document.write(res);
}<!DOCTYPE html>
<html>
<body>
<input type="text" value="test" id="testInput"></input>
<button onclick="myFunction()" id="testCode">Click</button>substring should be called on string variable
Docs: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/substring
Like so
const test = document.getElementById('your-id')
test.value = test.value.substring(0, 6);
