if statement of button found

My goal is, if a page contains the specified button, click it, and increase the amt_clicked by 1. When amt_clicked is greater than 15, wait for 60 seconds and reset amt_clicked. I have no idea how do this if statement. Example:
var amt_clicked = 0;
while (1) {
while (amt_clicked < 15) {
if (button found) { // this is where I am lost
iimPlay("TAG POS={{amt_clicked}} TYPE=BUTTON ATTR=TXT:Get");
amt_clicked++;
}
}
iimPlay("WAIT SECONDS=60");
amt_clicked = 0;
}

This will run 20 times per second, using the window.setInterval() function:
var amt_clicked = 0;
var amt_cooldown = 1200;
setInterval(function(){
if (amt_cooldown === 0)
amt_cooldown = 1200;
else if (amt_cooldown < 1200)
amt_cooldown -= 1;
else if (amt_clicked > 15) {
amt_clicked = 1;
amt_cooldown -= 1;
} else {
amt_clicked -= 1;
//Click
}, 50);

You can use combination of setInterval and setTimeout.
I have added comments to code for you to understand.
var amt_clicked = 0;
var setTimeoutInProcess = false;
//processing the interval click function
setInterval(() => {
checkButtonAgain();
}, 200);
function checkButtonAgain() {
var element = document.getElementById('iNeedtoBeClicked');
//if clicked 15 times then need to wait for 60 seconds
if (amt_clicked === 15) {
if (!setTimeoutInProcess) {
setTimeoutInProcess = true;
setTimeout(function() {
//resetting the amt-clicked
amt_clicked = 0;
setTimeoutInProcess = false;
}, 60000);
} else {
console.log('waiting');
}
} else if (typeof(element) != 'undefined' && element != null) {
//triggering click and increasing the amt_clicked
element.click();
amt_clicked++;
}
console.log(amt_clicked);
}
<button id="iNeedtoBeClicked">Click ME Button</button>

why two $scopes updates at the same time, duplicate data

I have this piece of code
$scope.addToOrder = function(index) {
var tempItem = $scope.item;
if (tempItem[index].validate == true){
if (_.isEmpty($scope.item2) == true) {
$scope.item2.push(tempItem[index]);
} else {
for (var i = 0; i < $scope.item2.length; i++) {
if ($scope.item2[i] == tempItem[index]) {
break;
}
if (i == $scope.item2.length - 1) {
$scope.item2.push(tempItem[index]);
}
}
}
}
}
I want to push data from one object to other (item to item2), it works well, but when i change data from item also item2 updates i dont want this.
What i missing?

As is, you are using an object reference. Then if modify one, the othes one is modified too.
You could use angular.copy
$scope.addToOrder = function(index) {
var tempItem = $scope.item;
var itemCopy = angular.copy(tempItem[index]);
if (tempItem[index].validate == true){
if (_.isEmpty($scope.item2) == true) {
$scope.item2.push(itemCopy);
} else {
for (var i = 0; i < $scope.item2.length; i++) {
if ($scope.item2[i] == tempItem[index]) {
break;
}
if (i == $scope.item2.length - 1) {
$scope.item2.push(itemCopy);
}
}
}
}
}

use angular.copy to cope by value
angular.copy($scope.item1, $scope.item2);
or
$scope.item1 = angular.copy($scope.item2);

javascript for loop dosn't loop through users created

OK so I am making a register and login for a forum using javascript and localstorage. "School assignment" My problem is that when i created multiple user and store them in the localstorage, my for loop does not loop through them all, only the first one. So i can only access the forum with the first user i create.
function login () {
if (checklogin()) {
boxAlert.style.display = "block";
boxAlert.innerHTML = "Welcome" + "";
wallPanel.style.display = "block";
} else {
boxAlertfail.style.display = "block";
boxAlertfail.innerHTML = "Go away, fail";
}
}
function checklogin (){
for (var i = 0; i < aUsers.length; i++){
if (aUsers[i].email == inputLoginMail.value && aUsers[i].password == inputLoginPassword.value){
return true;
}else{
return false;
}
}
}

how about:
function checklogin() {
var validLogin = false;
for (var i = 0; i < aUsers.length; i++) {
if (aUsers[i].email == inputLoginMail.value
&& aUsers[i].password == inputLoginPassword.value) {
validLogin = true;
break;
}
}
return validLogin;
}

Ouch! You are returning false on very first attempt. The best way is to set a variable and then check for it.
function checklogin() {
var z = 0;
for (var i = 0; i < aUsers.length; i++) {
if (aUsers[i].email == inputLoginMail.value && aUsers[i].password == inputLoginPassword.value) {
z = 1;
break;
} else {
z = 0;
}
if (z == 1) {
// User logged in
} else {
// Fake user
}
}

Javascript setInterval unwanted pause

I am trying to create an animation with a few images in javascript and I have the code working, but after it runs through images in reverse then it pauses slightly before it starts going forward again. I'm wondering how I get rid of the pause?
Here is the code in action http://isogashii.com/projects/javascript/ch10/dp10-6.html
HTML
<img id="pin" src="assets/pin0.gif" alt="pin animation" />
Javascript
var pin = new Array(9);
var curPin = 0;
var x = false;
// caching images
for (var imagesLoaded=0; imagesLoaded < 9; ++imagesLoaded) {
pin[imagesLoaded] = new Image();
pin[imagesLoaded].src = "assets/pin" + imagesLoaded + ".gif";
//starts pinF function when all images are cached
if (imagesLoaded == 8) {
setInterval("pinF()", 120);
}
}
function pinF() {
if (x == true) {
--curPin;
if (curPin == 0) {
x = false;
}
}
if (x == false) {
++curPin;
if (curPin == 8) {
x = true;
}
}
document.getElementById("pin").src = pin[curPin].src;
}

in the x == true portion of the if statement, you should set the curPin to be one otherwise you are duplicating the curPin = 1.
http://jsfiddle.net/A77cx/
function pinF() {
if (x == true) {
--curPin;
if (curPin == 0) {
curPin = 1;
x = false;
}
}
if (x == false) {
++curPin;
if (curPin == 8) {
x = true;
}
}
document.getElementById("pin").src = pin[curPin].src;
}

Currently, you do two "frames" of pin1. Change the logic of pinF not to do that.
To be specific, the first time x == true and curPin == 2, the first if executes, reducing curPin to 1.
The second time, x == true still, the first if brings curPin down to 0 and inverts x. Then, the second if increments curPin back to 1.

Simulating shuffle in js

All,
I have three cards which can be shuffled by the user, upon hover, the target card pops to the top, the last card on top should sit in the second position. While with the code below, I can have this effect in one direction (left to right), I am struggling to come up with logic & code for getting the effect to work in both directions without having to write multiple scenarios in js (which doesnt sound like very good logic).
Hopefully the demo will do a better explanation.
Code:
$(".cBBTemplates").on (
{
hover: function (e)
{
var aBBTemplates = document.getElementsByClassName ("cBBTemplates");
var i = 2;
while (i < aBBTemplates.length && i >= 0)
{
var eCurVar = aBBTemplates[i];
if (eCurVar === e.target)
{
eCurVar.style.zIndex = 3;
} else if (eCurVar.style.zIndex === 3) {
console.log (eCurVar);
eCurVar.style.zIndex = 3-1;
} else
{
eCurVar.style.zIndex = i;
}
i--;
}
}
});

Try this:
$(function(){
var current = 2;
$(".cBBTemplates").on (
{
hover: function ()
{
var target = this,
newCurrent, templates = $(".cBBTemplates");
templates.each(
function(idx){
if(this === target){
newCurrent = idx;
}
});
if(newCurrent === current){return;}
templates.each(function(index){
var zIndex = 0;
if(this === target) {
zIndex = 2;
}
else if (index == current) {
zIndex = 1;
}
$(this).css('zIndex', zIndex);
});
current = newCurrent;
}
});
});
