When you load [url] the searchbox contains the words "search reddit". Once it receives the focus by tabbing or clicking, the contents are cleared. However, there is no onfocus event, onclick event or any other script within the tag for this textbox. How is a textbox cleared without explicitly using an event?

I am having a dickens of a time figuring out how to add an event handler that clears my text fields when the clear button is clicked. This is the code that I've done but to no avail.
var $ = function (id) {
return document.getElementById(id);}
var calculate_click = function () {
var investment = parseFloat( $("investment").value );
var annualRate = parseFloat( $("rate").value );
var years = parseInt( $("years").value );
$("futureValue").value = "";
if (isNaN(investment) || investment <= 0) {
alert("Investment must be a valid number\nand greater than zero.");
} else if(isNaN(annualRate) || annualRate > 20) {
alert("Annual rate must be a valid number\nand less than or equal to 20.");
} else if(isNaN(years) || years > 50) {
alert("Years must be a valid number\nand less than or equal to 50.");
} else {
var monthlyRate = annualRate / 12 / 100;
var months = years * 12;
var futureValue = 0;
for ( i = 1; i <= months; i++ ) {
futureValue = ( futureValue + investment ) *
(1 + monthlyRate);
}
$("futureValue").value = futureValue.toFixed(2);
}}
var clear_click = function () {
var investment = parseFloat();
var annualRate = parseFloat();
var years = parseInt();
}
window.onload = function () {
$("calculate").onclick = calculate_click;
$("investment").focus();
}
