Need little help with the quiz app
I want to set time limit for each question in quiz module (say 30 seconds) and after that time, the
form will auto submit the question (auto submit = no option selected = unanswered).
There are 3 questions, so total time limit is 90 sec (30 sec each).
How to do that?
I'm doing this via XAMPP.
The link below provide the work so far
https://www.dropbox.com/s/4dzlgjtjzvs48vw/quiz.rar?dl=0
Thanks

You can use the setTimeout in JavaScript to trigger a function after a time. And once the next question has been loaded, again set the timer so that after exact 30 seconds it would again submit the form.
For example, to submit the form you might run this code,
setTimeout(submitForm, 30000);
function submitForm() {
document.myForm.submit();
}
Doing the same would submit them all. You can set the timeout to re-calculate the time once the question form is loaded again. It would be simple.

can you please elaborate by putting the code in the correct place
query($query) or die($mysqli->error.__LINE__);
$total = $results->num_rows;
//get a random question
if (empty($_SESSION['questionsUsed']))
{$questionSet = "SELECT * FROM `questions` ORDER BY RAND() LIMIT 1";}
else if ($total>count($_SESSION['questionsUsed'])) //there are more questions that haven't been asked
{
$questionsUsed = implode(',', $_SESSION['questionsUsed']);//join the array
$questionSet = "SELECT * FROM `questions` WHERE question_number not in ($questionsUsed)ORDER BY RAND() LIMIT 1";//get a random question that hasn't already been answered
}
else
{header("Location: final.php");
exit();}
$result = $mysqli->query($questionSet) or die($mysqli->error.__LINE__);
$question = $result->fetch_assoc();
//get random number
$random = $question['question_number'];
$_SESSION['questionsUsed'][] = $random;//add the question number to the list of questions asked
//get choices
$query = "SELECT * FROM `choices`
WHERE question_number = $random";
//get results
$choices = $mysqli->query($query) or die($mysqli->error.__LINE__);

Hi All,
I have an Unordered List which has many list items, and when we select a li, it opens up two spans, in one of the Span we have have radio buttons, I want to get the baseURL field that is attached to the li that I am selecting so that, can any one please help me any code snippet, link or even suggestion would be helpful. Thanks in advance.
All I want is either to get the report-url attribute or value of the span under the li that is selected or we can say active, I tried in the following ways but couldn't succeed, by the way I have to get these values when I click on the radio button that is within this list item, please help me.
var listitm = $("#li.report active");
var ttl = listitm.find('span.title').toString();
alert(ttl);
<li class="report active">

This line:
var listitm = $("#li.report active");
You're referencing "active" as if it's a tag. Add the "." before it, like so: "#li.report.active". You can chain the tag + classes.
Also, to read an attribute, you use jQuery's "attr()" method:
var title = listitm.find("span.title").text();
var url = listitm.find("span.title").attr("report-url");
djj55: Nice but may have a permission problem
Pete O'Hanlon: He has my permission to run it.

In Javascript document.activeElement will get the currently selected element.Or in the HTML you could add onclick="myFunction(this)".Or onchange="myFunction(this)" to the tag.

Hi All,
Can anybody let me know if I can hide a button without id or name, I am unable to hide neither the div or button from the following, I have used the below code, can anybody please help me in it.
I have been trying but not successful I am thinking that he was adding this div and close button in one popup and used in another popup, I am not sure how to handle in this situation as this person didn't use name nor id, any type of help, code snippet, any link or even suggestion would be helpful.
<div class="footer" style="position: absolute; bottom: 0px; width: 95%; margin-left: 2%; z-index: 3;">
<button style="width: 80px; background: url(http://localhost/ELMS/Image.axd?t=Close&r=211&g=211&b=211&p=20&h=25) 0% 0% no-repeat transparent;">Close</button>
</div>
<pre>
None of the following code hiding these html controls
<pre>
$('.footer').css('display', 'none');
$('.footer').hide();
$('.no-repeat.transparent;').css('display', 'none');

Why not to add an ID?
Skipper: We'll fix it.
Alex: Fix it? How you gonna fix this?
Skipper: Grit, spit and a whole lotta duct tape.

They are saying they want to run it only with class, if we add ids and if we use same id some where when we write functions or use popups we may get errors. Second this is what they are using here is we don't write jquery in aspx or ascx page but we have files called xx.js, common.js, Popup.js etc there we write all jquery, that is why we are not using ids.

Sure you can. You can get to any element in the html so long as you know it's position in relation to other elements.
I like to think of this approach as somewhat akin to climbing a tree with your eyes closed. So long as you've looked at the tree first and know where the branches are in relation to one another, you can climb away. It's fraught with danger though, because you can remember the relationships wrong or they can change from when you look at them to when you try to use them.
It may well be a poor analogy - but it works for me.
--
You can take advantage of a function querySelectorAll for this task. It allows you to pass in a string which would serve as a css selector for the element.
In your case, you want to target a button element that's contained in an element with the footer class. The css selector for this would be .footer button
See below for a short demo that allows you to hide/show the target button.
<!DOCTYPE html>
<html>
<head>
<script>
"use strict";
function byId(e){return document.getElementById(e);}
window.addEventListener('load', onDocLoaded, false);
function onDocLoaded()
{
byId('mHideShowBtn').addEventListener('click',onHideShowBtnClick,false);
}
function onHideShowBtnClick(e)
{
var tgtBtn = document.querySelectorAll('.footer button')[0];
if (tgtBtn.style.display == '')
tgtBtn.style.display = 'none';
else
tgtBtn.style.display = '';
}
</script>
<style>
</style>
</head>
<body>
<div class="footer" style="position: absolute; bottom: 0px; width: 95%; margin-left: 2%; z-index: 3;">
<button style="width: 80px; background: url(http://localhost/ELMS/Image.axd?t=Close&r=211&g=211&b=211&p=20&h=25) 0% 0% no-repeat transparent;">Close</button>

Please do not just dump all your code and expect people to explain it to you. You have been here long enough to know the procedure.

You'll have to look through the code for the carousel plugin and find the click event and instead change that code to run on a timer or however you want it to run.
There are only 10 types of people in the world, those who understand binary and those who don't.

Here is what I have so far. I cant get it to work.
This application stores the last name, first name, and score for one or more students and it calculates the average score for all of the scores that have been entered.
When the user clicks on the Clear button, this application clears the score data from this application.
When the user clicks on the Sort button, this application sorts the data in alphabetical order by last name.
