you can not write to client machine using javascript. You can use other technologies such as ActiveX to write to client machines, but they need explicit permission of the user.

where you want to save the log i.e. on server or client machine.
If client machine, then you need to use ActivX and need client permissions(As Yusuf said)
If server, then use the AJAX to send request and save the strokes in the file

Hi,
You can use javascript _doPostBack function to forcefully postback and let code-behind do the writing part to the log file. But this may not be a best practice.

Hi,
What is the goal of having the alt property in the image tag? When I hover over the image in IE7 then the text displays, in Firefox it does not display. Why is this? And what is a replacement for it?
Regards
|
|
|
|
|
the primamry purpose of alt is to show the text in case the image is not shown, or if image is not supported, such as text only browsers.
In IE, it used as tooltip as well, but that is IE's implementation and it is outside of the intended usage.
for more info see here[^]

Another reason for it is so that people who are unable to see the image can mouseover it and recieve an audible description of the image. See "screen readers"

Hi,
I am developing a donation website and I want to use paypal as the payment method, this is my first time to use paypal as a receiver, so I have a few technical questions:
1. How can I automatically accept payments?
2. How can I programmatically detect that someone has paid "some amount"?
3. I want the user to provide some information with his payment, such as Name, Gender, Country so how can this be done and how can it be linked to the payment??
any help please?
Thanks alot!
And ever has it been that love knows not its own depth until the hour of separation

Hi,
answer to your question:
1. You must have a member of paypal and your country must have a paypal unless you have a creadit card that accept paypal payment.
2. If you have a database that detect if someone pay you. But the quickest thing to know if someone paid you, logon to your account in paypal.
3. In your account at paypal.
Hope this one can help.
Thanks

1) You can make buttons in the "merchant" area of the paypal website.
2) You can use ipn and pdt. This is quite a big task so set aside some time - there are free scripts which you can find on paypal & google to help you. Involves using basic sockets.
3) ONce again you can use ipn &/or pdt. Alternatively you can make all the forms on your site and POST the info to Paypal.
IPN = Instant Payment Notification
PDT = Payment Data Transfer

I have html which contain iframe in it.
I have a button in my html which will call javascript(ajax) function and I will get server response from php script.
Normally if I want to display it in my main html, I can use:
var spantag=document.getElementById("displayCamera");
spantag.innerHTML=xhr.responseText;
How can I display the result into other html file/my iframe(let say I have span id in html of the iframe).
|
|
|
|
|
try window.iframeID.spanID
where iframeID is the id of your iframe and spanID is the id of your span.
|
|
|
|
|
Its done by
window.frames["displayCatalog"].document.getElementById("displayCamera").innerHTML = xhr.responseText;
So I have to change the iframe's attribute to name and not id.
Thanks though for the heads up.

try jquery or similar frameworks - easier than making your own scripts.

I want to use a script on my website that scores a multiple choice test, and what I have works pretty well. Before I use this script I want to make sure I understand everything it's doing. I understand most of what is happening, but I don't understand this particular loop:
for (i = 0; i < numberOfQuestions; i++) {
currentElt = i * numberOfChoices;
for (j = 0; j < numberOfChoices; j++) {
currentSelection = form.elements[currentElt + j];
if (currentSelection.checked) {
if (currentSelection.value == correctAnswers[i]) {
numberCorrect++;
break;
}
}
}
}
I understand that the first for loop is running through each question, but what is currentElt and why is it equal to the question times the number of answers? What is the second for loop doing with the numberOfChoices variable. The full script is below:
<script type="text/javascript">
var numberOfQuestions = 10;
var numberOfChoices = 4;
var correctAnswers = new Array(10);
correctAnswers = ["a", "b", "b", "a", "d", "a", "b", "b", "a", "c"];
function scoreQuiz(form) {
if (outOfTime == true) {
window.alert("You have exceeded the time limit of the test." + "\n" + "Please try again.");
return true;
}
var numberCorrect = 0;
var currentElt;
var currentSelection;
for (i = 0; i < numberOfQuestions; i++) {
currentElt = i * numberOfChoices;
for (j = 0; j < numberOfChoices; j++) {
currentSelection = form.elements[currentElt + j];
if (currentSelection.checked) {
if (currentSelection.value == correctAnswers[i]) {
numberCorrect++;
break;
}
}
}
}
form.correct.value = numberCorrect;
form.percentage.value = ((numberCorrect / numberOfQuestions) * 100) + "%";
}
var remainingTime = 600000;
var outOfTime = false;
function timeLeft() {
if (remainingTime <= 0) {
outOfTime = true;
}
else {
setTimeout("timeLeft()", (remainingTime));
remainingTime -= 1;
}
}
</script>
If anyone can help me understand this, or show me a better (simpler?) method of achieving the same thing I would greatly appreciate it.

dude,
your code is pretty wonky,
try this out to make a quiz
http://www.cj-design.com/products/free_downloads/javascript/cjmultiplechoicequiz[^]
your time calculation will never work since it is declared at the end of the function.
cullentElt is "current Element"
you are navigating to all the controls in your form and cheking one by one if they are checked or nor, if they are they shall be matched with the correct answer.
i would rather suggest you to use event, for change in option, calculate the score at that time itself,
it will make your code hardly 5-10 line.
read about "events" in javascript.
