Here is a really simple JavaScript calculator - with just 5 functions! (Add, subtract, multiply, divide, and power) This example can help you see how JavaScript evaluates math functions! Check it out!


Insert into <HEAD>
<SCRIPT LANGUAGE="JavaScript"> <!-- Original: Rick Johnson --> <!-- Web Site: http://members.tripod.com/~RickJohnson --> <!-- Begin function a_plus_b(form) { a=eval(form.a.value) b=eval(form.b.value) c=a+b form.ans.value = c } function a_minus_b(form) { a=eval(form.a.value) b=eval(form.b.value) c=a-b form.ans.value=c } function a_times_b(form) { a=eval(form.a.value) b=eval(form.b.value) c=a*b form.ans.value=c } function a_div_b(form) { a=eval(form.a.value) b=eval(form.b.value) c=a/b form.ans.value = c } function a_pow_b(form) { a=eval(form.a.value) b=eval(form.b.value) c=Math.pow(a, b) form.ans.value = c } // End --> </SCRIPT>

Insert into <BODY>
<CENTER> <FORM name="formx"><input type=text size=4 value=12 name="a"> <input type="button" value=" + " onClick="a_plus_b(this.form)"> <input type="button" value=" - " onClick="a_minus_b(this.form)"> <input type="button" value=" x " onClick="a_times_b(this.form)"> <input type="button" value=" / " onClick="a_div_b(this.form)"> <input type="button" value=" ^ " onClick="a_pow_b(this.form)"> <input type="number" size=4 value=3 name="b"> = <input type "number" value=0 name="ans" size=9> </FORM> </CENTER>
