I have three variables that I need to put in the innerHTML of four spans. The variables I use are seconds, accurateclick, and inaccurateclick. The process I use to get these variables is fine. The problem is I can't figure out how to bring them over to another function. I will make a replica of what I have. This will be a simpler version.
var x;
var y;
var z;
function A(){
x = 1;
y = 2;
z = 3;
B();
}
function B(){
var a = "";
var b = "";
var c = "";
var d = "";
a += x;
b += y;
c += z;
d += (x + y + z);
}
What would happen is, instead of a being equal to 1, b being equal to 2, and c being equal to 3, they would all equal to undefined. I don't know why that is happening when x, y, and z are global variables. I thought they should change when set to a different value.
Here is my actual code:
var seconds;
var accurateclicks;
var inaccurateclicks;
var windowheight = window.innerHeight;
var windowwidth = window.innerWidth;

Whenever I run it, it works up to this point
MiddleLabelTwo.innerHTML += seconds;
MiddleLabelThree.innerHTML += accurateclicks;
MiddleLabelFour.innerHTML += inaccurateclicks;
MiddleLabelFive.innerHTML += seconds + accurateclicks + inaccurateclicks;
It says seconds, accurateclicks, and inaccurateclicks are all undefined. I don't know why this would happen given that they were defined in the previous function [Game()].
try writing,
x = 1;
y = 2;
z = 3;
function A() {
B();
}
function B() {
var a = "";
var b = "";
var c = "";
var d = "";
a += x;
b += y;
c += z;
d += (x + y + z);
console.log(a, b, c, d);
}
A();
Reason: 'var' defines variables locally!
You did make two html files and this caused the js file to reload. This is why the global variables are declared again and are renewed to undefined.The solution is to work with one html file and to only reload the body.
My syntax was right, but as #Julie mentioned, the variables were being reloaded. How to get JS variable to retain value after page refresh? this helped me solve my problem.

I am trying to make a pong like game in html, but every time one player try to move the other movement will stop.
//javaScript
var p1axis = 40;
var p2axis = 40;
function input(event)
{
var x = event.charCode || event.keyCode;
if(x == 115)
{
p1axis += 2;
document.getElementById("p1").style.top = p1axis + "%";
}
if(x == 119)
{
p1axis -= 2;
document.getElementById("p1").style.top = p1axis + "%";
}
if(x == 108)
{
p2axis += 2;
document.getElementById("p2").style.top = p2axis + "%";
}
if(x == 111)
{
p2axis -= 2;
document.getElementById("p2").style.top = p2axis + "%";
}
}
I expect that both players will be able to play freely.
instead only one can move at once.
You can create an array and add keys as they are pressed. You will have to remove them as the key is released. Also, I just used keydown with jQuery, you can also use keydown with JavaScript.
var bKeys = [];
$('body').keydown(function(e) {
if (bKeys.includes(e.which) === false) {
bKeys.push(e.which);
}
});
$('body').keyup(function(e) {
bKeys.pop(e.which);
});
setInterval(() => {
console.log(bKeys);
}, 15);
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
Remember to click in the body when you run the code
var k1 = false, k2 = false, k3 = false, k4 = false;
var p1axis = 40;
var p2axis = 40;
function input(event)
{
var x = event.charCode || event.keyCode;
if(x == 115 || x == 83)
{
k1 = true;
}
if(x == 119 || x == 87)
{
k2 = true;
}
if(x == 108 || x == 76)
{
k3 = true;
}
if(x == 111 || x == 79)
{
k4 = true;
}
}
function remove(event)
{
var x = event.charCode || event.keyCode;
if(x == 115 || x == 83)

}
if(x == 119 || x == 87)
{
k2 = false;

if(x == 108 || x == 76)
{

if(x == 111 || x == 79)
{

}
}
function move()
{
if(k1)
{
p1axis += 1;
document.getElementById("p1").style.top = p1axis + "%";
}
if(k2)
{
p1axis -= 1;
document.getElementById("p1").style.top = p1axis + "%";

I made a snake game that works almost completely. I have one snake head, and an array which contains the head and all of the tails. When the snake eats a food, the food moves location, but my tail isn't getting bigger when I eat the food. I don't have an IMMENSE understanding of arrays, perhaps I'm doing it wrong?
Here is the code:
setSize(400, 400);
var background = new Rectangle(getWidth(), getHeight());
background.setPosition(0, 0);
background.setColor(Color.black);
add(background);
// ------------------------------------------------
var gameTime = 0;
var snakeX = (Randomizer.nextInt(0, 19)) * 20;
var snakeY = (Randomizer.nextInt(0, 19)) * 20;
var foodX;
var foodY;
var snakeFood = new Rectangle(20, 20);
snakeFood.setColor(Color.red);
var food_eaten = 0;
var snakeSpeed = 20;
var keyLeft = false;
var keyRight = false;
var keyUp = false;
var keyDown = false;
var snake_size = 10;
var snakeHead = new Rectangle(20, 20);
snakeHead.setColor(Color.green);
var snakes = [snakeHead];
// ------------------------------------------------
function start(){
setup();
keyDownMethod(checkKey);
setTimer(counter, 250);
}
function counter(){
gameTime += 0.25;
updateSnake();
}
function setup(){
foodX = (Randomizer.nextInt(0, 19)) * 20;
foodY = (Randomizer.nextInt(0, 19)) * 20;
snakeHead.setPosition(snakeX, snakeY);
add(snakeHead);
snakeFood.setPosition(foodX, foodY);
add(snakeFood);
}
function checkKey(e){
if(e.keyCode == Keyboard.LEFT){
keyRight = false;
keyUp = false;
keyDown = false;
keyLeft = true;
}else if(e.keyCode == Keyboard.RIGHT){
keyLeft = false;
keyUp = false;
keyDown = false;
keyRight = true;
}else if(e.keyCode == Keyboard.UP){
keyRight = false;
keyLeft = false;
keyDown = false;
keyUp = true;
}else if(e.keyCode == Keyboard.DOWN){
keyRight = false;
keyLeft = false;
keyUp = false;
keyDown = true;
}
}
function updateSnake(){
if(foodX == snakeX && foodY == snakeY){
eat();
}
var dirX = 0;
var dirY = 0;
if(keyLeft == true){
dirX = -(snakeSpeed);
dirY = 0;
}else if(keyRight == true){
dirX = snakeSpeed;
dirY = 0;
}else if(keyUp == true){
dirY = -(snakeSpeed);
dirX = 0;
}else if(keyDown == true){
dirY = snakeSpeed;
dirX = 0;
}
// moving the snake head
snakeHead.setPosition(snakeX + dirX, snakeY + dirY);
snakeX += dirX;
snakeY += dirY;
// moving the snake body
if(snakes.length > 1){
for(var i = 0; i < snakes.length; i++){
var curr_body = snakes[i];
curr_body.setPosition(snakeX + dirX, snakeY + dirY);
}
}
}
function eat(){
foodX = (Randomizer.nextInt(0, 19)) * 20;
foodY = (Randomizer.nextInt(0, 19)) * 20;
var tail = new Snake(snakeX, snakeY);
snakeFood.setPosition(foodX, foodY);
}
function Snake(x, y){
var snakeBody = new Rectangle(20, 20);
if(keyLeft == true){
snakeBody.setPosition(x + snake_size, y);
}if(keyRight == true){
snakeBody.setPosition(x - snake_size, y);
}if(keyUp == true){
snakeBody.setPosition(x, y + snake_size);
}if(keyDown == true){
snakeBody.setPosition(x, y - snake_size);
}
snakeBody.setColor(Color.green);
snakes.push(snakeBody);
add(snakeBody);
}
In your eat() function, you assign a new Snake object to a var tail, but then do nothing with it. I think you need to add it to your snakes array (which I assume represents the entire snake?)

This is the script, located at http://churchofcwa.wikia.com/wiki/MediaWiki:Common.js/bglinks.js, that I am encountering an error with css, this script was copied from https://www.biblegateway.com/public/link-to-us/tooltips/bglinks.js and is not made by me. The issue I am encountering is via the css page (MediaWiki:Common.css) when changing the color of the script by
.bg_popup-content-bible {color:#000000}
The font color of the p tag within that div does not change. Originally I had it set to the p tag specifically of that div, but a css checker said that styling would be overqualified, and it was not functional nevertheless. What the script does is take all Bible verses listed on a page, and automatically links them to Biblegateway and creates a preview popup when hovering. However, the font is very unreadable and so I have tried to change it to black.
The popup currently has a near-white font (that blends with the popup)
and needs to have a black font, with the rest of the page content needs the near white font. When the script runs through it generates a div surrounding each bible verse, and the js applies to it (the div in which the Bible verse text appears is in the bg_popup-content-bible with a <p> tag), making it popup like so.
I have noted that in the script there is a section that calls for a "addedCSS"
var addCSS = function() {
if (!addedCSS) {
var css = document.createElement('link');
css.type = "text/css";
css.rel = "stylesheet";
if (browser.search('MSIE 6.0') != -1) {
browser = 'ie6';
css.href = cdHost + '/theme/bglinks-ie.css';
} else {
css.href = cdHost + '/theme/popover.css';
}
css.media = "screen";
var n1 = document.getElementsByTagName("head")[0].childNodes[0]
n1.parentNode.insertBefore(css, n1);
addedCSS = true;
}
}
I do not believe it is possible to change the url that the addedCss pull from, from the MediaWiki:Common.css, as this script was not made for the specific system being used (when removing or altering the variable the script does not work). I don't know if this is not happening because of a javascript issue (which is beyond me, and it's difficult to alter the script without breaking it) or if it's just a matter of incorrect css, but I have been working on this for several months here and there, and would like to get this final detail to work.
Try changing it to
.bg_popup-content-bible {color:#000000 !important;}
Ignore the CSS specificity checker. I have tested the below css on your site and it works. Make sure to put it in your site.css.
.bg_popup-content-bible p {
color: #000000;
}
It needs to be written as above because it has to override the <p> styling you've already set earlier in site.css:
p {
color: #f5f5f5
}
EDIT
It is not a problem with the script. Based on what you have said in the comments it seems like you are unable to actually edit / output css. So the other option is just to modify the script you've posted above:
Change this:
tooltip.innerHTML = '<div class="bg_popup-header"><div class="bg_popup-header_title"><strong>'+reference_display+' '+tooltip_content.version+'</strong></div></div><div class="bg_popup-content"><div class="bg_popup-content-bible"><p>'+tooltip_content.text+' <a class="bg_popup-copyright" href="'+bgHost+tooltip_content.version_url+'" target="_blank">('+tooltip_content.version+')</a> <a class="bg_popup-more" href="'+bgHost+'/passage/?search='+tooltip_content.reference+'&version='+tooltip_content.version+'&src=tools" target="_blank">More</a></p></div></div><div class="bg_popup-footer"><a class="bg_popup-bglogo" href="'+bgHost+'/" target="_blank"></a></div>';
to this:
tooltip.innerHTML = '<div class="bg_popup-header"><div class="bg_popup-header_title"><strong>'+reference_display+' '+tooltip_content.version+'</strong></div></div><div class="bg_popup-content"><div class="bg_popup-content-bible"><p style="color:#000000">'+tooltip_content.text+' <a class="bg_popup-copyright" href="'+bgHost+tooltip_content.version_url+'" target="_blank">('+tooltip_content.version+')</a> <a class="bg_popup-more" href="'+bgHost+'/passage/?search='+tooltip_content.reference+'&version='+tooltip_content.version+'&src=tools" target="_blank">More</a></p></div></div><div class="bg_popup-footer"><a class="bg_popup-bglogo" href="'+bgHost+'/" target="_blank"></a></div>';
Given the way Stack formats the code above, to make it very clear you are editing the part of the line above that says:
<p>'+tooltip_content.text+'
and making it:
<p style="color:#000000">'+tooltip_content.text+'
I have a problem i want to check a variable.If its 0 then gain ++ after 1.5s.If its 10 then gain ++ after .4s.Its complicated.It doesnt really work.My code so far:
if(road == 1){setInterval(function(){stamina = stamina+1;document.getElementById("stamina").innerHTML = stamina;},1400);}
else if(road == 2){setInterval(function(){stamina = stamina+1;document.getElementById("stamina").innerHTML = stamina;},1300);}
else if(road == 3){setInterval(function(){stamina = stamina+1;document.getElementById("stamina").innerHTML = stamina;},1200);}
else if(road == 4){setInterval(function(){stamina = stamina+1;document.getElementById("stamina").innerHTML = stamina;},1100);}
else if(road == 5){setInterval(function(){stamina = stamina+1;document.getElementById("stamina").innerHTML = stamina;},1000);}
else if(road == 6){setInterval(function(){stamina = stamina+1;document.getElementById("stamina").innerHTML = stamina;},900);}
else if(road == 7){setInterval(function(){stamina = stamina+1;document.getElementById("stamina").innerHTML = stamina;},800);}
else if(road == 8){setInterval(function(){stamina = stamina+1;document.getElementById("stamina").innerHTML = stamina;},600);}
else if(road == 9){setInterval(function(){stamina = stamina+1;document.getElementById("stamina").innerHTML = stamina;},400);}
else if(road == 10){setInterval(function(){stamina = stamina+1;document.getElementById("stamina").innerHTML = stamina;},200);}
else{setInterval(function(){stamina++;document.getElementById("stamina").innerHTML = stamina;},1500);}
And the code to build a road is this:
function build_road() {
if ((wood + tavern) >= 29 && stone > 4 && road < 10) {
road++;
document.getElementById("road_count").innerHTML = road;
wood = (wood + tavern) - 20;
stone = stone - 5;
document.getElementById("wood").innerHTML = wood;
document.getElementById("stone").innerHTML = stone;
exp = exp + 20;
var x = document.getElementById("PROGRESS");
x.setAttribute("value", exp);
x.setAttribute("max", max);
if (exp == 100) {
exp = 0;
level++;
document.getElementById("level").innerHTML = level;
}
alert("Congratulations,You've create a Road,Now you gain stamina slightly faster.");
}
else {
alert("You need: 30Wood,5Stone .Maximum 10 Roads.")
}
}
Make reusable functions (it's often a good practice, when you a difficulties with a piece of code, to break it into small functions):
var staminaIncreaseTimer = null;
function configureStaminaIncrease(delay) {
if (staminaIncreaseTimer !== null)
clearInterval(staminaIncreaseTimer);
staminaIncreaseTimer = setInterval(function () {
increaseStamina();
}, delay);
}
function increaseStamina() {
stamina += 1;
document.getElementById("stamina").innerHTML = stamina;
}
Solution with an array (suggested by Jay Harris)
var roadIndex = road-1;
var ROAD_DELAYS = [1400, 1300, 1200, /*...*/];
var DEFAULT_DELAY = 1500;
if (roadIndex < ROAD_DELAYS.length) {
configureStaminaIncrease(ROAD_DELAYS[roadIndex]);
} else {
configureStaminaIncrease(DEFAULT_DELAY);
}
Solution with a switch instead of you if-elseif mess:
switch (road) {
case 1:
configureStaminaIncrease(1400);
break;
case 2:
configureStaminaIncrease(1300);
break;
case 3:
configureStaminaIncrease(1200);
break;
//and so on...
default:
configureStaminaIncrease(1500);
}
