第一步：把如下代码加入<body>区域中
<scr ipt LANGUAGE="java-scr ipt">
<!-- Begin
function doit() {
form.input.value = eval(form.input.value)
}
function Cos() {
x = form.input.value
if (x == ) alert( Error: Input Required )
else form.input.value = Math.cos(x)
}
function Sin() {
x = form.input.value
if (x == ) alert( Error: Input Required )
else form.input.value = Math.sin(x)
}
function Ln() {
x = form.input.value
if (x == ) alert( Error: Input Required )
-first step : put the following code to join lt; Bodygt; Region lt; scr ipt LANGUAGE = "java-scr ipt" gt; Lt; !-- Begin function doit () (form.input.value = eval (form.input.value)) Cos function () (x = form.input.value if (x ==) alert (Error : Input Required) = else form.input.value Math.cos (x)) function Sin () (x = form.input. value if (x ==) alert (Error : Input Required) = else form.input.value Math.sin (x)) function Ln () (x = form.input.value if (x ==) alert (Error : Input Required)
