Trying to figure out a problem with the "Optional" values in a list box so I am going to keep it as simple as I can..
I am trying to calculate the optional value of a list box in stead of programming it the long way around.
I created a list box with several peoples names, like John, Sue, and Mary.
I have assigned each name a numeric "optional" values
I know the code in the list box should be:
Normally, I would code this along the lines of:
But I want to figure out how to select the Optional Value from the list, and multiply it by time instead of doing the SELECTEDNAMELISTBOX=="John" route..
The exercise problem is to "MODIFY the code in the "calculate_click" event so interest is added to future value just once each year for the number of years that they were entered by the user". The calculation as you see it below assumes an amount is invested MONTHLY (not just once), and the interest is calculated accordingly. This is what I think the problem is trying to calculate: using a $100 one time investment at 10% interest (compounded once annually) for one year = $110 as the future value. For two years, the future value should equal $121 (110 + (110*.10)). Okay, if my math is wrong, let me know. This is what I'm trying to get it to match to.
I have been able to modify the calculate_click function to compound the interest annually (it does it monthly now). Cool. I cannot get it to stop adding $100 annually. See my math above? I think that's the answer. My manipulation of the code yields $110 for the first year, $231 for the second year, etc. The $231 is incorrect cuz it adds an extra $100. See, this is a simple interest calculator I can't figure out! The original code is below that calculates the investment as a monthly investment as opposed to one-time. To avoid confusion, I did not include any of my modifications. But yeah. I know that the major culprit is how the "for" loop is being executed. I've highlighted where I think the code needs to be changed, but I haven't changed it here. Note the first function is a shortcut to execute getElementbyID.
The Code:
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 = ""; .....

This is a makeshift sort function for a table. I want to replace a div contents with a javascript function call. It works fine if I define the individual case, but the general case doesn't work.

The following script works fine in IE6. In FF 1.0.7, it doesn't display the response text. The alert()'s in the script show that:
1) the script successfully creates the request object
2) 'http_request.status' starts off equal to 0
3) the readystate displays: 1, 1, 2, 4
4) an error occurs when the script tries to access the .status property of the request object after the request has been sent and the readyState reaches 4(line marked in red below).

I'm having some trouble trying to get a simple GET to work.
I have a page called 1.php with the following code:
This all works fine when I link directly to the page (I.e [url]), however when I load this page through jquery (so the url becomes [url]) the GET functionality stops working.
I've tried to address this issue multiple times, and yet IE 8 simply ignores it. I know jquery has the capability of operating correctly with other examples, but the below code just doesn't seem to satisfy it.[code]

I've got a form textarea on my site, which after being submitted is stripped by my php file.
Then my javascript kicks in and does some analysis of the entered text. However everytime the user entered a hard return within the textarea my javascript gives me an error 'tekenreeks niet afgesloten' which means something like 'string is not closed'.
Therefore I decided to replace all occurences of chr(10) and chr(13) with ok2 (just some random characters), I did this with php which worked fine, and I didn't get the javascript error.
However I need to reshow the entered text (original) to the user, so I need to restore the old values. I tried result.waarde.replace('ok2', 'chr(13)'); but it doesn't work, as it still displays ok2.
I'm no expert in javascript, but how can I replace those characters by the hard returns?
Oh yeah I'll show some more coding, perhaps the error can be found there code...
I've done some small adjustments to my clients site, but it won't show properly in IE (the shadowbox js at least.).
