show and hide several random divs using jquery - javascript

i am developing a jquery application. I have 10 divs with quotes. I am trying to create a function that takes a number and randomly displays that number of quotes from the 10 divs for 10 seconds and hide the divs. Then repeat the process again. I have not been able to do it please help me out. here is my code:
$(document).ready(function(){
var div_number = 4;
var used_numbers = new Array();
var todo = setInterval(showQuotes(),3000);
function showQuotes(){
used_numbers.splice(0,used_numbers.length);
$('.quotes').hide();
for(var inc = 0; inc<div_number; inc++) {
var random = get_random_number();
$('.quotes:eq('+random+')').show();
}
$('.quotes').fadeOut(3000);
}
function get_random_number(){
var number = randomFromTo(0,9);
if($.inArray(number, used_numbers) != -1) {
get_random_number();
}
else {
used_numbers.push(number);
return number;
}
}
function randomFromTo(from, to){
return Math.floor(Math.random() * (to - from + 1) + from);
}
});

Changes I made:
hide the .quotes on launch via a stylesheet
run showQuotes() once before setInterval(showQuotes,10000), and
add a .delay() before fading the quotes out
Py's 'return' added to get_random_number
http://jsfiddle.net/cMQdj/1/
the changed JavaScript:
$(document).ready(function () {
var div_number = 4;
var used_numbers = new Array();
showQuotes();
var todo = setInterval(showQuotes, 10000);
function showQuotes() {
used_numbers.splice(0, used_numbers.length);
$('.quotes').hide();
for (var inc = 0; inc < div_number; inc++) {
var random = get_random_number();
$('.quotes:eq(' + random + ')').show();
}
$('.quotes').delay(6000).fadeOut(3000);
}
function get_random_number() {
var number = randomFromTo(0, 9);
if ($.inArray(number, used_numbers) != -1) {
return get_random_number();
} else {
used_numbers.push(number);
return number;
}
}
function randomFromTo(from, to) {
return Math.floor(Math.random() * (to - from + 1) + from);
}
});
and add to your stylesheet:
.quotes {display:none}

I didn't test everything, but i already see one point that might block you, the get_random_number does not always return a number. To do so, it should be
function get_random_number(){
var number = randomFromTo(0,9);
if($.inArray(number, used_numbers) != -1)
{
return get_random_number();
}
else
{
used_numbers.push(number);
return number;
}
}
Hope that helps.

JS random order showing divs delay issue

I got function within JS which is supposed to show random order divs on btn click.
However once the btn is clicked user got to wait for initial 10 seconds ( which is set by: setInterval(showQuotes, 10000) ) for divs to start showing in random order which is not ideal for me.
JS:
var todo = null;
var div_number;
var used_numbers;
function showrandomdivsevery10seconds() {
div_number = 1;
used_numbers = new Array();
if (todo == null) {
todo = setInterval(showQuotes, 10000);
$('#stop-showing-divs').css("display", "block");
}
}
function showQuotes() {
used_numbers.splice(0, used_numbers.length);
$('.container').hide();
for (var inc = 0; inc < div_number; inc++) {
var random = get_random_number();
$('.container:eq(' + random + ')').show();
}
$('.container').delay(9500).fadeOut(2000);
}
function get_random_number() {
var number = randomFromTo(0, 100);
if ($.inArray(number, used_numbers) != -1) {
return get_random_number();
} else {
used_numbers.push(number);
return number;
}
}
function randomFromTo(from, to) {
return Math.floor(Math.random() * (to - from + 1) + from);
}
Question: How to alter the code so upon the btn click divs will start showing right away without initial waiting for 10 seconds? (take in mind I want to keep any further delay of 10 seconds in between of each div being shown)
Thank you.
Call it when you begin the interval
todo = setInterval((showQuotes(),showQuotes), 10000);

Assigning number to .find(type) in Jquery

I have a function that allows me to select a random radio button and click on it. But on different pages I have different .find(type). Example:
Page1.html: controlTypeToIterateOn='label'
Page2.html: controlTypeToIterateOn=':radio'
//Radio button
function randomNumberGenerator(max, min) {
var randomNumber = Math.floor(Math.random() * (max - min + 1) + min);
return randomNumber;
}
function SelectRandonRadioButton(radioButtonContainer, controlTypeToIterateOn) { //Genereal function
var radios = $(radioButtonContainer).find(controlTypeToIterateOn);
if (controlTypeToIterateOn == ':radio')
controlTypeToIterateOn = 1;
else if (controlTypeToIterateOn == 'label')
controlTypeToIterateOn = 0;
var randomnumber = randomNumberGenerator(radios.length - 1, 0);
//randomizing number
$(radios[randomnumber]).click();
return $(radios[randomnumber]);
}
function SelectLiveRandomRadioButton(radioButtonContainer, controlTypeToIterateOn) {
var elem = SelectRandonRadioButton(radioButtonContainer, controlTypeToIterateOn);
$(elem).mousedown();
}
function call() {
$(".YesNoRadio").each(function() {
SelectLiveRandomRadioButton($(this), 1);
});
}
call();
My if condition that checks the input type does not seem to work. I want to assign a numeric value that I can pass in my SelectLiveRandomRadioButton() function that's inside the call function. For example if I pass '0',my controlTypeToIterateOn = 'label', if I pass 1, my controlTypeToIterateOn = ':radio'. Anyone who can help me with this? Thanks.
I am not sure what you are trying to do, but from looking at your code, I guess you might want to do something like this:
function SelectRandonRadioButton(radioButtonContainer, controlTypeToIterateOn) {
var toFind;
if (controlTypeToIterateOn === 1) {
toFind = ':radio';
} else if (controlTypeToIterateOn === 0) {
toFind = 'label';
}
var hits = $(radioButtonContainer).find(toFind);
var randomnumber = randomNumberGenerator(hits.length - 1, 0);
$(hits[randomnumber]).click();
return $(hits[randomnumber]);
}
function call() {
$(".YesNoRadio").each(function() {
// where 1 would find radio, and 0 label
SelectLiveRandomRadioButton($(this), 1);
});
}
call();

JavaScript function dosen't work correct

I have a function that checking board is there a searching element.
First script creating a board with different elements. Element in the square next to board is element that user has to find on the board and click them.
User has to click (as quick as possible) all searching elements. After click on element function checking a board, is there more elements. If yes then nothing happen and user has to click another one. If on board there isn’t searching elements then function display a time and new board create.
But some reason function works correct only first time after page load. Latter function ignore more then one element on board or see element that doesn’t exist on board any more.
Can you tell me what is wrong.
Part of code bellow and there is a link to testing page.

Js and Divs, (even <div> is difference)

I Have find a javascript code that works perfectly for showing a DIV.
but this code works only for showing one div for each page.
i want to include many DIVS for hiding and showing in the same page.
I was try to replace the div id and show/hide span id with a rundom php number for each include, but still is not working.
so how i have to do it?
the JS code:
var done = true,
fading_div = document.getElementById('fading_div'),
fade_in_button = document.getElementById('fade_in'),
fade_out_button = document.getElementById('fade_out');
function function_opacity(opacity_value) {
fading_div.style.opacity = opacity_value / 100;
fading_div.style.filter = 'alpha(opacity=' + opacity_value + ')';
}
function function_fade_out(opacity_value) {
function_opacity(opacity_value);
if (opacity_value == 1) {
fading_div.style.display = 'none';
done = true;
}
}
function function_fade_in(opacity_value) {
function_opacity(opacity_value);
if (opacity_value == 1) {
fading_div.style.display = 'block';
}
if (opacity_value == 100) {
done = true;
}
}
// fade in button
fade_in_button.onclick = function () {
if (done && fading_div.style.opacity !== '1') {
done = false;
for (var i = 1; i <= 100; i++) {
setTimeout((function (x) {
return function () {
function_fade_in(x)
};
})(i), i * 10);
}
}
};
// fade out button
fade_out_button.onclick = function () {
if (done && fading_div.style.opacity !== '0') {
done = false;
for (var i = 1; i <= 100; i++) {
setTimeout((function (x) {
return function () {
function_fade_out(x)
};
})(100 - i), i * 10);
}
}
};
Check out the Fiddle, you can edit code based on your needs ;)
$(function() {
$('.sub-nav li a').each(function() {
$(this).click(function() {
var category = $(this).data('cat');
$('.'+category).addClass('active').siblings('div').removeClass('active');
});
});
});
finaly i found my self:
<a class="showhide">AAA</a>
<div>show me / hide me</div>
<a class="showhide">BBB</a>
<div>show me / hide me</div>
js
$('.showhide').click(function(e) {
$(this).next().slideToggle();
e.preventDefault(); // Stop navigation
});
$('div').hide();
Am just posting this in case someone was trying to answer.

javascript countdown with showing milliseconds

I want to do a count down and want to show like format as Minutes:Seconds:Milliseconds. I made a count down with jquery plug-in countdown but it shows just Minutes:Seconds format.
Is there any way to make it right?
Many Thanks!
Hi guys I have developed a code for my self use the following code
counter for 20 seconds
var _STOP =0;
var value=1999;
function settimer()
{
var svalue = value.toString();
if(svalue.length == 3)
svalue = '0'+svalue;
else if(svalue.length == 2)
svalue = '00'+svalue;
else if(svalue.length == 1)
svalue = '000'+svalue;
else if(value == 0)
svalue = '0000';
document.getElementById('cn1').innerHTML = svalue[0];
document.getElementById('cn2').innerHTML = svalue[1];
document.getElementById('cn3').innerHTML = svalue[2];
document.getElementById('cn4').innerHTML = svalue[3];
value--;
if (_STOP==0 && value>=0) setTimeout("settimer();", 10);
}
setTimeout("settimer()", 10);
Try this: http://jsfiddle.net/aamir/TaHtz/76/
HTML:
<div id="timer"></div>
​
JS:
var el = document.getElementById('timer');
var milliSecondsTime = 10000;
var timer;
el.innerHTML = milliSecondsTime/1000;
timer = setInterval(function(){
milliSecondsTime = milliSecondsTime - 1000;
if(milliSecondsTime/1000 == 0) {
clearTimeout(timer);
el.innerHTML = 'BOOOOM';
}
else {
el.innerHTML = milliSecondsTime/1000;
}
},1000);
​
If you want to make your own timer.
read this earlier question
How to create a JQuery Clock / Timer
Try setting the format parameter - http://keith-wood.name/countdownRef.html#format
On further reading, this plugin doesn't do milliseconds. At this point, you either have to edit the actual plugin code or find a new plugin.
I completely agree with #Matt Ball's comment.It may also cause the browser to crash.
Why don't you try this solution instead
jQuery 1 minute countdown with milliseconds and callback
I did it like this (generic counter from N to X (X > N)):
var dynamicCounterAddNewValue = 20;
var currentDynamicUpdater;
function dynamicCounterForValueForControlUpdater(_updaterData) {
_updaterData.from += dynamicCounterAddNewValue;
if (_updaterData.from > _updaterData.to) {
_updaterData.from = _updaterData.to;
}
_updaterData.c.html(_updaterData.from.toString());
if (_updaterData.from < _updaterData.to) {
currentDynamicUpdater = setTimeout(
dynamicCounterForValueForControlUpdater,
10,
{
c: _updaterData.c,
from: _updaterData.from,
to: _updaterData.to
}
);
}
else {
clearTimeout(currentDynamicUpdater);
}
return;
}
// _c -> jQuery object (div,span)
// _from -> starting number
// _to -> ending number
function dynamicCounterForValueForControl(_c, _from, _to) {
clearTimeout(currentDynamicUpdater);
dynamicCounterForValueForControlUpdater(
{
c: _c,
from: _from,
to: _to
}
);
return;
}
EDIT: Updated version (more flexible - for N elements one after another):
(input element is Array of elements for making them dynamic-counts)
var dynamicCounterTimeout = 10;
var currentDynamicUpdater;
function odcArray(_odca) {
this.odca = _odca;
return;
}
function odc(_c, _from, _to) {
this.c = _c; // $('#control_id')
this.from = _from; // e.g. N
this.to = _to; // e.g. M => (M >= N)
var di = parseInt(_to / 45, 10);
if (di < 1) {
di = 1;
}
this.dynamicInc = di;
return;
}
function dynamicCounterForValueForControlUpdater(_odca) {
if (
_odca.odca === null
||
!_odca.odca.length
) {
clearTimeout(currentDynamicUpdater);
return;
}
var o = _odca.odca[0];
o.from += o.dynamicInc;
if (o.from > o.to) {
o.from = o.to;
_odca.odca.shift(); // Remove first element
}
o.c.html(o.from.toString());
currentDynamicUpdater = setTimeout(
dynamicCounterForValueForControlUpdater,
dynamicCounterTimeout,
_odca
);
return;
}
function dynamicCounterForValueForControl(_odca) {
clearTimeout(currentDynamicUpdater);
// SETUP all counters to default
for (var i = 0; i < _odca.odca.length; i++) {
_odca.odca[i].c.html(_odca.odca[i].from.toString());
}
dynamicCounterForValueForControlUpdater(
_odca
);
return;
}
