jump/dropdown menu input form on current page. 1

I posted this in the html forum and was told I would have better luck here.

I am wondering if a jump/dropdown menu can insert a form onto the current page (below the dropdown menu).

For example I have my default page with a dropdown with 8 selection options. Right now each option goes to a specific calculation page. Each calculation page is just a form with different calculations. I don't want to have to format each calculation page if I don't have to. I think an include file would work well, but I am not sure if it is possible to do.

Any suggestions or ideas would be appreciated.

Oh, and the page can be reloaded when the dropdown menu is selected if it is easier that way.

Does each calculation page have the same fields and just different methods of calculating? If so, then the method is easier.

Otherwise, you would have to have the contents of each form on the page:

Code: 
<html>
<head>
<title>Forms</title>
<script type="text/javascript">
<!-- hide

var last=null;

function setShown(index)
{
  var obj = document.getElementById("formdiv" + index);
  if (last != null)
  {
    last.style.display="none";
  }
  last = obj;
  obj.style.display = "block";
}

// end hide -->
</script>
<style type="text/css">
<!--

.formdiv {
    display: none;
    }

-->
</style>
</head>
<body>
<a href="javascript:setShown(1)">Form 1</a><br>
<a href="javascript:setShown(2)">Form 2</a><br>
<a href="javascript:setShown(3)">Form 3</a><br>
<div id="formdiv1" class="formdiv">
<form name="form1">
<textarea name="txtarea">Form 1</textarea>
</form>
</div>
<div id="formdiv2" class="formdiv">
<form name="form2">
<input type="radio" name="radio1">Radio 1<br>
<input type="radio" name="radio1">Radio 2<br>
</form>
</div>
<div id="formdiv3" class="formdiv">
<form name="formdiv3">
<input type="checkbox" name="check1">Checkbox 1<br>
<input type="checkbox" name="check2">Checkbox 2<br>
</form>
</div>
</body>
</html>

Yes, each form has the same fields and just different methods of calculating.

How do I go about this way, or is this what your code does?

Add in your own functions and fields.

Code: 
<html>
<head>
<title>Forms</title>
<script type="text/javascript">
<!--

var method = "calc1";

function setMethod(newfunc)
{
  method = newfunc;
}

function doMethod()
{
  eval(method + "()");
}

function calc1()
{
  // Calculate the first way
}
function calc2()
{
  // Calculate the second way
}
function calc3()
{
  // Calculate the third way
}

// end hide -->
</script>
</head>
<body>
<form name="topform">
<input type="radio" name="method" value="calc1" onclick="setMethod(this.value);">Method 1<br>
<input type="radio" name="method" value="calc2" onclick="setMethod(this.value);">Method 2<br>
<input type="radio" name="method" value="calc3" onclick="setMethod(this.value);">Method 3<br>
</form>
<br><br>
<form name="calcform" onsubmit="doMethod();">
Field 1<br>
<input type="text" name="field1"><br>
Field 2<br>
<input type="text" name="field2"><br>
Field 3<br>
<textarea name="field3"></textarea><br>
</form>
</body>
</html>

That kind of looks like what I want. The only thing, is I have several functions on each of my calculation page. I am having trouble getting this to work correctly. Here is the code on 1 of my calculation pages.

Code:

var max_units = 10000; // quantities in excess of max_units all have the same unit price
var currency = "$"; // currency sign used in 'formatMessage()'

Now each other calculation page is identical, with different numbers applied. Since this has multiple functions I can't get your code to work with this.

I know this code isn't great either, I found a free javascript and changed it to what I needed to do. I know the ideal would to have 1 page calculate based on what is selected, but that is beyond my javascript abilities.

Is findPrice the only function that is different for each page?

If so, copy each different version of it into the first page, along with the other functions once. Change the names of the function so they are different (probably findPrice1, findPrice2, etc.). Change the values of the radio buttons to reflect the new names, and reply if there is any problem.

Actually what is different on each page is this

Code: 
var interval_0 = 0;
var interval_500 = 111;
var interval_1000 = 123;
var interval_1500 = 136;
var interval_2500 = 146;
var interval_5000 = 215;
var interval_10000 = 336;
var max_units = 10000; // quantities in excess of max_units all have the same unit price
var currency = "$"; // currency sign used in 'formatMessage()'
// Edit this function to reflect your discount prices! 
function getDiscountPrice(units) {
// Note: It is important to work your way down from max to min amounts!
if (units > 5000) return 0.0242;
if (units > 2500) return 0.0276;
if (units > 1500) return 0.01;
if (units > 1000) return 0.026;
if (units > 500) return 0.024;

if (units <= 0) return 0;
}

what is messing me up is the variables. I assume I will have to make all the variables on this page, then adjust the functions to call the specific variable I want. Such as the formatMessage and add a bunch more else if statements? Can you point me in the right direction? You have been a big help so far.

I should mention it is just the values of the variables that are different the names are all the same. The same is true for what is returned by the if statements. Just the values are changed, not the intervals.

Here you go... Untested, but should work.

/* Edit this to reflect each set of intervals. Page 1 includes
 * function 1, and has intervals found in the first section, etc. */

var intervals = new Array();

/*
Repeat for each page. Each one should have increasing numbers, so the second one would be intervals[1][0], the third, intervals[2][0], etc.
*/

intervals[0] = new Array(); // Do not change
intervals[0][0] = "getDiscountPrice1"; // Name of function
intervals[0][1] = "$"; // Currency
intervals[0][2] = 0; // interval_0
intervals[0][3] = 111; // interval_500
intervals[0][4] = 123; // interval_1000
intervals[0][5] = 136; // interval_1500
intervals[0][6] = 146; // interval_2500
intervals[0][7] = 215; // interval_5000
intervals[0][8] = 336; // interval_10000

// Repeat the above

var index = 0; // Default function is 0

/*
Here, add in all the functions that stay the same (all but getDiscountPrice). In all functions, replace the interval variables with the equivalent in the array: intervals[index][2] is interval_0, intervals[index][5] is interval_1500, etc.

function getDiscountPrice1(units) {
// Note: It is important to work your way down from max to min amounts!

}

/*

// Do not change this.

function setMethod(i)

}

// end hide -->

What do I do with the getDiscountprice in this function. How do I determine which discountprice to pull from?

Code: 
function findPrice() {
var units = getNumberOfUnits();
var unit_price = getDiscountPrice(units);
var alt_units = getAltUnits(units);
var alt_unit_price = getDiscountPrice(alt_units);
var result;
if (units < 500) result = formatMessage0(0,0);
else if (units == 10000) result = formatMessage10000(0,0);
else if (units == 5000) result = formatMessage5000(0,0);
else if (units == 2500) result = formatMessage2500(0,0);
else if (units == 1500) result = formatMessage1500(0,0);
else if (units == 1000) result = formatMessage1000(0,0);
else if (units == 500) result = formatMessage500(0,0);
else if (units > 10000) result = formatMessage10000(units, unit_price);
else if (units > 5000) result = formatMessage5000(units, unit_price);
else if (units > 2500) result = formatMessage2500(units, unit_price);
else if (units > 1500) result = formatMessage1500(units, unit_price);
else if (units > 1000) result = formatMessage1000(units, unit_price);
else if (units > 500) result = formatMessage500(units, unit_price);
else if ((units * unit_price) < (alt_units * alt_unit_price)) 
result = formatMessage500(units, unit_price); 
else
result = formatMessage500(alt_units, alt_unit_price);
showResult(result);
}

Sorry, didn't mention that.

Code: 
var unit_price = eval( intervals[index][0] + "(" +  units + ")" );

It Works!!! Thank you very much. If I could give you more than 1 star I would.

Another quick question, is there a way to have the form reset or recalculate when the user clicks on a different button. Right now when you select radio button 1, then input the units it works fine, but when you go back up and change the button radio button, the price remains.

Thanks!

If you want to trim your code down more (cut all of those repeating formatMessages), just reply.

Sure if you would like to help me out, I would gladly take the help. Also I don't know if you saw my previous post about the reseting of the form when a new button is selected, but I would like that as well.

never mind about the selecting different buttons, I figured it out.
