The document describes a JavaScript function that validates user input of a character between 'd' and 'm'. The function gets the character value from an input field, checks if it is a character and between 'd' and 'm', and displays the result. The correct code to do this validation is the first option, which checks if the character is not NaN, and is greater than or equal to 'd' and less than or equal to 'm'.

1. <h1>JavaScript Can Validate Input</h1>
<p>Please input a char between 'd' and 'm':</p>
<input id="character">
<button type="button" onclick="myFunction()">Submit</button>
<p id="WEBT2300"></p>
<script>
function myFunction() {
var x, text;
//Get the value of the input field: id="numb"
x = document.getElementById("character").value;
// If x is Not a char
// or >= than 'd' or <= than 'm'
else {
// text is ok
}
document.getElementById("WEBT2300").innerHTML = text;
}
</script>
Which code will do the above?
Question 11 options:
if (!NaN(x) && x >= 'd' && x <= 'm') {
text = "Input not valid";
} else {

2. // text is ok
text = "Input OK";
}
if (!isNaN(x) && x > 'd' || x < 'm') {
text = "Input not valid";
} else {
text = "Input OK";
}
if (!NaN(x) && x >= 'd' || x <= 'm') {
text = "Input not valid";
} else {
// text is ok
text = "Input OK";
}
if (!isNaN(x) || x >= 'd' && x <= 'm') {
text = "Input not valid";
} else {
// text is ok
text = "Input OK";
}
if (!NaN(x) && x >= 'd' && x <= 'm') {
text = "Input not valid";
} else {

3. // text is ok
text = "Input OK";
}
if (!isNaN(x) && x > 'd' || x < 'm') {
text = "Input not valid";
} else {
text = "Input OK";
}
if (!NaN(x) && x >= 'd' || x <= 'm') {
text = "Input not valid";
} else {
// text is ok
text = "Input OK";
}
if (!isNaN(x) || x >= 'd' && x <= 'm') {
text = "Input not valid";
} else {
// text is ok
text = "Input OK";
}
