If you're looking to dive into JavaScript, a great starting point can be found here. While creating an ASP project for a simple calculator could be an option, it's not necessary and might be more than what you need.
For those interested in jQuery, there is a fantastic tutorial for a jQuery calculator that can be accessed here.
If you're looking to create a simple calculator in a web browser, having knowledge of HTML is essential. Without it, you won't be able to have any input controls for your users. Fortunately, making a basic calculator with just a few lines of JavaScript - no jQuery required - is quite manageable. Here's an example:
<script type="text/javascript">
function calculate()
{
var v = document.getElementById("data");
alert(eval(v.value));
}
</script>
<input type="text" id="data" />
<input type="button" value="Calculate" onclick="calculate()" />
Simply enter your equation into the text box (e.g., 2 + 4 / 10) and click the button to get the result!
var counter = 0;
function addCounter(value) {
var inputValue = document.getElementById("text1").value;
var length = inputValue.length;
var lastChar = inputValue.charAt(length - 1);
if (lastChar != value) {
counter = 0;
}
counter = parseInt(counter) + parseInt(1);
if (counter <= 1) {
document.getElementById("text1").value += value;
} else {
document.getElementById("text1").innerHTML = '';
}
}
function event1(input) {
document.getElementById("text1").value += input;
var evalValue = document.getElementById("text1").value;
document.getElementById("text3").value = eval(evalValue);
document.getElementById("text1").value = eval(evalValue);
}
function event2() {
var x = document.getElementById("text1").value;
document.getElementById("text1").value = eval(x);
}
function event3() {
document.getElementById("text1").value = "";
document.getElementById("text3").value = "";
}
function event4() {
var inputValue = document.getElementById("text1").value;
var newInputValue = inputValue.slice(0, -1);
document.getElementById("text1").value = newInputValue;
