The game is quite simple you click on the start button to begin then move your mouse along the track until you reach the end then the timer stops and shows you the score. If you go out of the track you get a score of zero.
Why don't my mouseOver functions work?
Link to my full code: http://www.codecademy.com/TictacTactic/codebits/AQBK4L/edit
Thank you in advance!
var score = 1000;
var timer = setInterval(countDown(), 1000);
$(document).ready(function() {
$('#start').click(function() {
$('#game').mouseover(function() {
stopTimer();
score = 0
$('#points').html(score)
});
$('#end').mouseover(function() {
stopTimer()
$('#points').html(score)
});
});
});
function countDown() {
score = score - 1;
}
function stopTimer() {
clearInterval(timer);
}
Most events are in lowercase, like mouseover, mouseout etc. There are also others that have capitals, like DOMContentLoaded. Most (if not all) programming languages are case-sensitive, watch out for these.
Try this
var clicked = false;
$('#start').click(function() {
if(!clicked){
clicked = true;
}
});
$("#game").hover(function(){
if(clicked){
stopTimer();
score = 0;
$("#points").html(score);
}
});
$("#end").hover(function(){
if(clicked){
stopTimer();
$("#points").html(score);
}
});
Then later if you don't want the hover event to work just set clicked to false I.E : clicked = false;

I can't for the life of my figure out how to get this to work bug free.
The button in the code below needs to do three things.
Start a countdown when clicked (works)
End the countdown automatically, and reset itself when it reaches 0(works)
Reset itself prematurely if its clicked in the middle of a countdown(works, sort of)
Bug: when clicked repeatedly it starts multiple countdowns, and more or less breaks. It needs to either reset itself or start a countdown if clicked repeatedly. There should never be more than one countdown.
It works fines as long as people press the button, wait a second, and then press it again to stop it.
The bug I'm running into is if someone spam clicks it, it starts multiple countdowns and generally just breaks the button. I've tried a lot of different methods to fix it, and this is the closest I've gotten.
var i = 29;
let running=false;
$("#startButton").click(function () {
if(running==false){
var countdown = setInterval(function () {
$("#startButton").text("Reset Timer");
running=true;
$("#stopWatch").html(i);
i--;
if (i <0)
{
$("#startButton").text("Start Timer");
running=false;
clearInterval(countdown);
i = 29;
$("#stopWatch").html(i);
}
$("#startButton").click(function () {
$("#startButton").text("Start Timer");
running=false;
clearInterval(countdown);
i = 29;
$("#stopWatch").html(i+1);
});
}, 1000);
}
});

Welcome to Stack Overflow #William!
I'm not sure what this means: Reset itself prematurely if its clicked in the middle of a countdown(works, sort of). But I managed to fix your bug on spamming button click and for item 3, i just do reset the countdown from initial state. See snippets below:
// Get attribute value from div `stopwatch`. This is for resetting from default value.
var initial = $('#stopWatch').attr("value");
// Assigned initial value to var i.
var i = initial;
$("#stopWatch").html(i);
let running = false;
// Created a separate function to call from button click.
function run(timer = true) {
if (timer) {
running = true;
$("#startButton").text("Reset Timer");
$("#stopWatch").html(i);
var countdown = setInterval(function () {
i--;
$("#stopWatch").html(i);
if (i <= 0) {
running = false;
$("#startButton").text("Start Timer");
clearInterval(countdown);
i = initial;
$("#stopWatch").html(i);
}
}, 1000);
} else {
running = false;
clearInterval(countdown);
i = 0;
$("#startButton").text("Start Timer");
}
}
$("#startButton").click(function () {
// Check if its not running and var i is not 0
if(!running && i != 0) {
run();
// Check if its running and var i is not 0 to ensure that if someone spam the button it just reset the countdown.
} else if (running && i != 0) {
// Will return the else{} on function run().
run(false);
}
});

Added some comments on the snippet. Feel free to ask if you have any questions.
I made a control (numeric spinner up and down), to work in a table:
JSFIDDLE: http://jsfiddle.net/Leandro1981/wn8vd/1/
and I want simulate the "mousedown, increment while mouse button is helding" but I can't do it. I tried to mix it with the following and functional script:
JSFIDDLE: http://jsfiddle.net/Leandro1981/kKW85/
but I couldn't make it.
My last attempt here:
http://jsfiddle.net/Leandro1981/S8Zt9/1/
Maybe the wrong is the
timeout = setInterval(function () {
But I couldn't figure out. I'm using bootstrap 3, so I can't use some JQuery UI plugins...
Any help will be preciated!
Please comment below if you have any question, comment or anything to improve this question, and sorry for my english :)
Please be free to use my code/control in any way.
Thanks and kind regards
Write a factory to set up each control so you get a closure over the variables, now it's just a matter of being able to make it work given the relevant elements. For this, you'll need to
Listen for mousedown on the up and down nodes to set off the changes
Start a timeout loop to keep doing your change
Listen for mouseup on window to ensure you cancel the timeout loop (you may also want to listen for mouseout/loss of focus)
So all together,
function spinFactory(node, up, down) { // I wrote this vanilla :D
var spinning, delta;
window.addEventListener('mouseup', stopSpin);
function spin() {
node.value = +node.value + delta;
spinning = setTimeout(spin, 500);
}
function stopSpin() { // maybe also invoke this on mouseout/loss of focus
window.clearTimeout(spinning);
delta = 0;
}
up.addEventListener('mousedown', function spinUp() {
delta = 1;
spin();
});
down.addEventListener('mousedown', function spinDown() {
delta = -1;
spin();
});
}
// apply to your control, used a bit of jQuery to make life easier
$('.PNET-spinner').each(function () {
spinFactory(
this.getElementsByTagName('input')[0],
$(this).find('.btn:first-of-type')[0],
$(this).find('.btn:last-of-type')[0]
);
});
DEMO
I have updated the Fiddle here ... Please check this and it might helps you..
Script
$('.PNET-spinner .btn:first-of-type').on('mousedown', function (e) {
var timer, proxy = this;
timer = setInterval(function () {
increment(proxy);
}, 200);
$(document).one("mouseup", function () {
increment(proxy);
if (timer) clearInterval(timer);
});
});
$('.PNET-spinner .btn:last-of-type').on('mousedown', function () {
var timer, proxy = this;
timer = setInterval(function () {
decrement(proxy);
}, 200);
$(document).one("mouseup", function () {
decrement(proxy);
if (timer) clearInterval(timer);
});
});
function increment(proxy) {
var numupdown = $('.PNET-spinner input', $(proxy).closest("tr"));
var inputValue = parseInt($(numupdown).val(), 10);
inputValue++;
$(numupdown).val(inputValue);
}
function decrement(proxy) {
var numupdown = $('.PNET-spinner input', $(proxy).closest("tr"));
var inputValue = parseInt($(numupdown).val(), 10);
if (inputValue > 1) {
inputValue--;
$(numupdown).val(inputValue);
}
}
You simply need to take care of two things. First, your function to increment and decrement the value in the textbox should be called again and again till user do mouseout or mouseup. Second, make surethis has the right value in var numupdown = $('.PNET-spinner input', $(this).closest("tr"));
Following code shows how to do it for the increment button. Similar thing, you can implement for decrement button.
var timeout;
var inc = function () {
var myThis = this;
var numupdown = $('.PNET-spinner input', $(this).closest("tr"));
var inputValue = parseInt($(numupdown).val(), 10);
inputValue++;
console.log(inputValue);
$(numupdown).val(inputValue);
clearTimeout(timeout);
timeout = setTimeout(function(){
//http://stackoverflow.com/questions/3630054/how-do-i-pass-the-this-context-to-a-function
inc.apply(myThis, arguments);
}, 1000);
};
var incStop = function(){
clearTimeout(timeout);
}
$('.PNET-spinner .btn:first-of-type').on('mousedown', inc);
$('.PNET-spinner .btn:first-of-type').on('mouseup', incStop);
$('.PNET-spinner .btn:first-of-type').on('mouseout', incStop);
Check this DEMO here.
This is a followup to this question, where I found out how to make code be repeated every x seconds. Is it possible to make an event that can change this? I.e. I have a checkbox which is meant to control whether this is repeated or not, so I figured I'd need something like this:
$(checkbox).bind("change", function() {
switch(whether if it is ticked or not) {
case [ticked]:
// Make the code repeat, while preserving the ability to stop it repeating
case [unticked]:
// Make the code stop repeating, while preserving the ability to start again
}
});
I have no idea what I could put in the cases.
You can do it by assigning your setInterval function to a variable.
var interval = setInterval(function() { }, 1000);
and then you can stop setInterval by
clearInterval(interval);
p.s.
to start your interval you need to call var interval = setInterval(function() { }, 1000); again
You can either stop and start the interval:
var timer;
function start() {
timer = window.setInterval(function(){
// do something
}, 1000);
}
function stop() {
window.clearInterval(timer);
}
start();
$(checkbox).bind("change", function() {
if ($(this).is(':checked')) {
start();
} else {
stop();
}
});
Or you can have a flag causing the interval to skip the code:
var enabled = true;
var timer = window.setInterval(function(){
if (!enabled) {
// do something
}
}, 1000);
$(checkbox).bind("change", function() {
enabled = $(this).is(':checked');
});
function fooFunc() {
$('#foo').text(+new Date());
}
var id;
var shouldBeStopped = false;
$('input').change(function() {
if (shouldBeStopped)
clearInterval(id);
else
id = setInterval(fooFunc, 200);
shouldBeStopped = !shouldBeStopped;
});
Live DEMO
I have this button which is not working correctly for hold button for a period (but it works like click only).
Where i was trying to do if the button is hold for greater/equal then 2 seconds then callfunction1, if the button was pressed less then 2 seconds then callfuntion2.
var clickDisabled = false;
function clickLocker() {
/* #Button: 2 seconds */
clickDisabled = true;
setTimeout(function(){clickDisabled = false;}, 2000);
}
function callfunction1() { // you have hold he button for greater then or equal 2 second }
function callfunction2() { // you have hold the button less then 2 second }
$('.button').live("click",function()
{
if (clickDisabled) {
alert("locked for 2 second");
return;
}
clickLocker();
});
I think this solution should work. I have not tested it but it should give you the right idea.
var startTime;
function callfunction1() { // you have hold he button for greater then or equal 2 second }
function callfunction2() { // you have hold the button less then 2 second }
function buttonDownEvent() {
var Time = new Date();
startTime = Time.getTime();
}
function buttonUpEvent() {
if(new Date().getTime() - startTime < 2000)
callfunction2()
else
callfunction1()
}
$('.button').live("mousedown",function()
{
buttonDownEvent();
});
$('.button').live("mouseup",function()
{
buttonUpEvent();
});
Listen for both events, mousedown and mouseup, measuring the time between both:
var timeDown;
var timeUp;
$('.button').live("mousedown",function(){
timeDown = event.timeStamp;
});
$('.button').live("mouseup",function(){
timeUp = event.timeStamp;
time = timeUp-timeDown;
if (time>2000){
function1();
}else{
function2();
}
});
please note that event.timeStamp wont work well in firefox. For firefox you can do (new Date).getTime();
You can do this using events to the mouseup and mousedown events and timing the difference between them. Also, you need to remember which element caused the click - if the user released the mouse on a different element then it should just do the "non 2-second hold" function. A JSFiddle showing this working is available here: http://jsfiddle.net/35rw3/6/.
That was a great suggestion from slash. This is how you can do this
var clickstart;
var clickstop;
$("a").on('mousedown', function(e) {
clickstart = e.timeStamp;
}).on('mouseup', function(e) {
clickstop = e.timeStamp- clickstart
if(clickstop >= 2000) two()
else one();
});

Updates:
It might be necessary to track the mouse movement like #MarkRhodes wrote in his comments. So for that, check this update
I have a div that appears when the user's mouse leaves the document with a survey about my site.
I don't want to ask them to do the survey if they move their mouse out in the first couple of minutes while browsing around, so I was wondering if I can set a timeout/sleep on when this mouseleave function would activate.
Here is my code without the timeout:
$(document).mouseleave(function () {
document.getElementById("Overlay1").style.display = "";
});
Thanks a lot!
You can use window.setTimeout to enable the function after a certain time.
Example:
window.setTimeout(function(){
$(document).mouseleave(function () {
console.log('mouse leave');
document.getElementById("Overlay1").style.display = "";
});
console.log('initiated');
},5000);
you could call the same function encapsulated in asetTimeout function call :
$(document).mouseleave(function() {
var seconds = 3;
//execute the function in 3 seconds
setTimeout(function(){
document.getElementById("Overlay1").style.display = "";
},seconds*1000);
});
