Javascript Title Insurance Calculator - HELP

demiurgik · Jul 25, 2003

the formula for the title insurance calculator is as follows:

up to the first $100,000 $5.75 per $1,000.00

over 100,000 and up to $1 Million $5.00 per $1,000.00

over $1 Million and up to $5 Million $2.50 per $1,000.00

over $5 Million and up to $10 Million $2.25 per $1,000.00

over $10 Million $2.00 per $1,000.00

it is divided into fraction of $100.00 however, any fraction of $100 should be considered as a full $100.00 for purpose of Calculating Premiums.

This will give us the promulgated rate we then want a separate column to show what they would be saving with us. We will then discount by 40% so a $1,000 policy would cost $600

I have code for the entire thing except the discounted 40% - I need help with this part.

Can anyone please help me?

Math is fun!

Before you do that final (*0.6) multiplcation, multiply everything by some fixed number such that all your operations happen in integers to avoid any floating point errors.

Edward,
Thanks for your tip, do you think I could post the code and you could help me with the last portion.
My partner bailed on the project so now I'm left with something I don't really understand.

I know that I have to take the answer from the first part of the equation and multiply that by the .60, but I'm not quite sure how to display it in a corresponding text box.

Any help would be greatly appreciated!!!

EdwardMartinIII · Jul 25, 2003

Yeah, post what you feel like posting and I'll take a look.

When you post it, please put it between "

Code:

" blocks so it doesn't get all Ashcrofted.

Oy, I mean to hit "Preview" to make sure the codes didn't get invisibled, but the darn flesh was unwilling.

Be sure to post code between

The last part I need to do is to take the Purchase Price Cost and multiply that by .60 and display it in a text box already named NDTECost. Thanks so much for your time.

Function:
calcFLInsurPremium

Description:
This function will calculate Mortgage Premium Cost on the given mortgage amount.

The algorithm used is:

POLICY AMOUNT
Up to $100,000.00 (Amount/1000.00) * 5.75)
Over $100,000.00 up to 1,000,000.00 575.00 + ((Amount-100,000.00/1000.00) * 5.00)
Over $1,000,000.00 up to 5,000,000.00 5075.00 + ((Amount-1,000,000.00/1000.00) * 2.50)
Over $5,000,000.00 up to 10,000,000.00 15075.00 + ((Amount-5,000,000.00/1000.00) * 2.25)
Over $10,000,000.00 up to 10,000,000.00 26325.00 + ((Amount-10,000,000.00/1000.00) * 2.00)

If minimum premium cost to charge is always $100.00.

This is really ugly. I'm digging through...

Does this actually run on the web or on a nonIE browser? There are pathnames with spaces and all those lines in the JS file pop up as errors all over the place.

I think your first problem is that you're using FrontPage to create a website. I highly recommend you find some other tool.

I'll let you know what I find, but I'm letting you know now that to even get the thing to run without errors, I'm dinkin' with all sorts of fiddly bits of code.

Cheers,

EdwardMartinIII · Jul 29, 2003

Okay, it's a mess and it fails to function because it can't find some other function.

I printed the code out and tacked it to the wall and threw a dart and it landed on this line:

Code:

txTmp = nCost.toString();

so I guess you can try changing that to

Code:

txTmp = (nCost * 0.6).toString();

Alternately, you can preceded it like this:

Code:

nCost =* 0.6;
txTmp = nCost.toString();

Cheers,

Edward

here is how the calculator should work:

http://www.ndte.com/Rate

Calculator1.htm

the last box i need to take the middle box's number and multiply that by .60.

EdwardMartinIII · Jul 31, 2003

A URL with a space is an invalid URL.

Did the line change work?

demiurgik · Jul 31, 2003

sorry - try this link:

http://www.ndte.com/RateCalculator1.htm

not really quite sure what the line change is doing, i need to take the answer that is produced in the middle box and multiply that by .6 and then display that number in the third box.

EdwardMartinIII · Jul 31, 2003

Is it supposed to always display "0.00" in the third box, no matter what I type?

When you run this from the link you posted above, what do you see in the other two boxes when you enter "500000000" in the first box and then click on the yellow image?

Have you tried running this under any browser other than IE?

Cheers,

[monkey]

Edward

"Cut a hole in the door. Hang a flap. Criminy, why didn't I think of this earlier?!" -- inventor of the cat door

demiurgik · Jul 31, 2003

i have not been able to program the code for the third box to display the correct information.

when you put 50000000 in the first box, the output in the second box is : 1006325.00

now based on 1006325.00 the third box should take that number and multiply it by .60 to get 603795.

i have not tried it in any other browser yet as i havent gotten the code complete.

EdwardMartinIII · Jul 31, 2003

I would suggest that you download a copy of Mozilla (for example) and try running your page under that as well. While you're still developing it. This way, you discover problems "early" and can fix them before you publish the page.

I realize you inherited this code. It is a complete mess and a real pain to trace through. Are you sure this isn't one of the runners-up in a most-obfuscated code contest?

As far as I can tell, there is no place at all where a value is even assigned to this text box except when it is constructed, where the "0.00" is assigned to it as a value.

Are you telling me that a person enters a single number in the first box, the second box gets populated by the formula in your first post, and then the third box gets populated by 60% of the second box? Is that all you want to do?

Cheers,

[monkey]

demiurgik · Jul 31, 2003

yes that is all that i want to do! ;-)

EdwardMartinIII · Aug 1, 2003

Okay.

Find the code in your .js file that looks like this:

Code:

		} /**** rnd2DecPlaces ****/

and replace it with this:

Code:

                  var NDTECostValue = (txObjTo.value / 100) * 60;
                  if (!Number.prototype.toFixed)
                  {
                    Number.prototype.toFixed = function(decimals)
                    {

                    var decimals = decimals || 2 // defaults to two
                    var catalyst = Math.pow(10, decimals);

                    var fixedNum = Math.round(parseFloat(this) * catalyst) / catalyst;
                    var sFixedNum = new String(fixedNum)
                    var aFixedNum = sFixedNum.split(&quot;.&quot;)

                    var i = (aFixedNum[1]) ? aFixedNum[1].length : 0
                  // append decimal point if needed
                    if (i == 0) { sFixedNum += &quot;.&quot; }
                  // append zeros if needed
                    while (i < decimals) {
                      sFixedNum += &quot;0&quot;
                      i++
                      }
                    return sFixedNum 
                    }
                  }
                  document.ratescalc.NDTECost.value = (new Number(NDTECostValue).toFixed(2));
		} /**** rnd2DecPlaces ****/

Copy the code exactly from this post. It'll do the calculation and round to the nearest penny.

I'm using a method Xutopia posted in thread216-518499, which was a damn handy piece of code. All I did was wade through this spaghetti to figure out where to drop it.

Hope that helps!

demiurgik · Aug 4, 2003

do i place that whole code infront of what is already existing.

replace the existing variables for that section?

EdwardMartinIII · Aug 4, 2003

Just find the code line I specified and replace it the code I supplied.

You are replacing a single line of code with a bunch of lines of code. I even kept one line (the line you're replacing) as a reference point. This is as it should be. Do not change anything else in any other file at all. These are the files I downloaded from your website. I got the thing to work, so I know it's good.

I would recommend highly against monkeying around with other bits of the code. It is very messy. FrontPage is simply one of the best reasons I've encountered for the necessity of inventing some sort of a long-range slapping device. Wait, what am I thinking -- FrontPage is a long-range slapping device! [lol]

Hope that gets you where you want to be.
