So Basicly if i click the burtton, it should change the variables to 1.
However, it dosen't print out "It's happening now" as it should.
Could someone please explain what's wrong with this??
Best regards daniel.
var reg_uname_done = 0;
var reg_pword1_done = 0;
var reg_pword2_done = 0;
var reg_email_done = 0;
$("#first_nav_bar li:first").click(function(event) {
reg_uname_done = 1;
reg_pword1_done = 1;
reg_pword2_done = 1;
reg_email_done = 1;
});
if(reg_pword1_done === 1 && reg_pword2_done === 1 && reg_email_done === 1 && reg_uname_done === 1) {
console.log('its happening now');
}
The reason why this is not happening is b/c the js file is going down, and you haven't "clicked" the <li> element yet, therefore your variables are still equal to 0. You have to set a function inside of that event.
See fiddle
var reg_uname_done = 0;
var reg_pword1_done = 0;
var reg_pword2_done = 0;
var reg_email_done = 0;
$("#first_nav_bar li:first").click(function (event) {
reg_uname_done = 1;
reg_pword1_done = 1;
reg_pword2_done = 1;
reg_email_done = 1;
check();
})
function check() {
if (reg_pword1_done === 1 && reg_pword2_done === 1 && reg_email_done && reg_uname_done) {
console.log('its happening now');
}
}

I have very little to no knowledge when it comes to using JavaScript. I have 24 of the same image given an id from q1 - q24. my code allows for the 24 images to be changed to image2 one at a time, but I need for it to stop and display a text/alert when image2 is clicked.
<script>
{
let num = 1;
function sequence()
{
let back = 1;
while (back < 25)
{
if(back == 1)
{
document.getElementById("q24").src = "question.jpg";
}
else
{
document.getElementById("q" + (back-1)).src = "question.jpg";
}
back++
}
document.getElementById("q" + num).src = "question2.png";
num = num + 1;
if(num > 24){num = 1;}
}
setInterval(sequence, 500);
}
</script>
Save the interval timer to a variable. Then add a click listener to all the images that stops the timer if the current image is the one showing question2.jpg.
{
let num = 1;
for (let i = 1; i <= 24; i++) {
document.getElementById(`q${i}`).addEventListener("click", function() {
if (i == num) {
clearInterval(interval);
}
});
}
let interval = setInterval(sequence, 500);
function sequence() {
for (let i = 1; i <= 24; i++) {
if (i == num) {
document.getElementById(`q${i}`).src = "question2.jpg";
} else {
document.getElementById(`q${i}`).src = "question.jpg";
}
num = num + 1;
if (num > 24) {
num = 1;
}
}
}
}
While I don't fully understand your use case, you could create a click event listener on the document and check the target's src in it.
document.addEventListener('click', function(e) {
if (e.target.src === 'question2.png') {
alert('Clicked question 2');
}
});
I am trying to use an empty array which fills when clicking on an image send the Image ID to a findMatch() function which in turn is used to insert the a match in a isMatch() function. My isMatch() function is not working correctly. I have tried debugging in Chrome but this is not helping. Any help or advice would be appreciated. I need to clear the array after 2 images are selected.
function isMatch() {
if ((count === 1) && (pic == 1)) {
cMatch.unshift(arrMatch);
match1 = imgID;
}
if ((count === 2) && (pic == 1)) {
// var index2=deClick(clicked);
cMatch.push(arrMatch);
match2 = imgID; {
if (cMatch[0] === cMatch[1]) {
bMatch = true;
cMatch.length = 0;
cMatch = [];
count = 0;
match1 = 0;
match2 = 0;
} else {
bMatch = false;
document.getElementById(match1).src = defaultImage;
document.getElementById(match2).src = defaultImage;
cMatch.length = 0;
cMatch = [];
count = 0;
match1 = 0;
match2 = 0;
}
//else{bMatch=false;}}
}
if (count > 2) {
document.getElementById(match1).src = defaultImage;
document.getElementById(match2).src = defaultImage;
count = 0;
return bMatch;
}
}
}
The code when stepping in Chrome seems to work but when I use in the browser it does not work at all.
The concept is simliar to a slider. Here is the JsFiddle
Each section is set to:
visibility: hidden;
until assigned the "anim-in" class. The issue is with var $currSection and $nextSection that need the var $rightCounter to correctly evaluate.
var $currSection = $rightCounter;
var $nextSection = $rightCounter + 1;
$rightCounter is updated in the counter function:
function counter (event){
var $counterSelect = $(this).attr('id');
if ( $counterSelect == "right") {
if ( $rightCounter >= 0 && $rightCounter <= 4){
$rightCounter += 1;
console.log($rightCounter);
if ($leftCounter <= 0) {
$leftCounter = 0;
console.log($leftCounter);
}
else {
$leftCounter -= 1;
console.log($leftCounter);
}
}
}
else {
if ($leftCounter >= 0 && $leftCounter <= 4){
$leftCounter += 1;
console.log($leftCounter);
if ($rightCounter <= 0) {
$rightCounter = 0;
console.log($rightCounter);
}
else {
$rightCounter -= 1;
console.log($rightCounter);
}
}
}
animOut();
return $rightCounter;
};
The animOut function uses $currSection and $nextSection to redistribute classes, but they are not updating with the $rightCounter?
Note: the console logs are there to show what the vars are evaluating to
Okay I successfully created a basic slideshow but I wanted to add more effects and such to make it look more realistic. I am doing some coding but I don't know what is wrong. I end up crashing my MOZILLA everytime I run the script. Can anyone help me do this correctly? And not to mention I don't want any kind of jQuery modification to my code
JavaScript
var img = new Array("a.jpg","b.jpg","c.jpg");
var len = img.length - 1;
var pos = 0;
function slid(e){
pos = pos + e;
if(pos < 0)
{
pos = len;
}
if(pos > len)
{
pos = 0;
}
var a = 1;
var i = 1;
while(i<=50)
{
function op(a) {
a -= 0.02;
if(a < 0)
{
a = 1;
}
document.getElementById("slide").style.opacity = a;
}
i++;
}
document.getElementById("slide").src = img[pos];
return false;
};
and yeah it's not fading(in this case changing opacity) help me on that too?
Take a look here:
while(i<=50)
{
function op(a) {
a -= 0.02;
if(a < 0)
{
a = 1;
}
document.getElementById("slide").style.opacity = a;
}
}
You are not incrementing your 'i' counter variable, resulting in an infinite loop, and hence browser crashing. Replace with this:
while(i<=50)
{
function op(a) {
a -= 0.02;
if(a < 0)
{
a = 1;
}
document.getElementById("slide").style.opacity = a;
}
i++; //increment the counter variable to prevent an infinite loop
}
I'm having some issues with this. For some reason, updateCurrentItem is always called with the same parameter regardless.
function updatePromoList(query) {
query = query.toUpperCase();
clearCurrentList();
var numItems = 0;
currentItem = 0;
result_set = cached[query.charAt(0)][query.charAt(1)][query.charAt(2)];
for(i in result_set){
if(numItems >= NUMBER_MATCHES){
$("<li/>").html("<span style='color: #aaa'>Please try to limit your search results</span>").appendTo("#possibilities").mouseover(function(event){ updateCurrentItem(numItems+1); });
break;
}
promo = result_set[i];
found_number = false;
if (!promo.client)
found_number = (promo.prj_number.toString().substr(0,query.length) == query) ? true : false;
if (query.length >= MATCH_NAME) {
if(promo.prj_name && typeof promo.prj_name == 'string'){
found_name = promo.prj_name.toUpperCase().indexOf(query);
} else {
found_name = -1;
}
if (promo.client)
found_client = promo.client_name.toString().indexOf(query);
else
found_client = -1;
} else {
found_name = -1;
found_client = -1;
}
if(found_client >= 0) {
var thisIndex = numItems+1;
console.log("setting", thisIndex);
$("<li/>").text(promo.client_name).bind('click',function(e){ updatePromoChoice(e,promo); }).appendTo("#possibilities").mouseover(function(event){ updateCurrentItem(thisIndex); }); } else if(found_name >= 0 || found_number) { var thisIndex = numItems+1;
console.log("setting", thisIndex);
$("<li/>").text(promo.prj_number+": "+promo.prj_name).bind('click',function(e){ updatePromoChoice(e,promo); }).appendTo("#possibilities").mouseover(function(event){ updateCurrentItem(thisIndex); });
}
if(found_number || found_client >= 0 || found_name >= 0){
numItems++;
}
}
}
function updateCurrentItem(i){
currentItem = i;
console.log("updating to", i);
}
The results of running this are:
setting 0
setting 1
setting 2
setting 3
setting 4
setting 5
setting 6
setting 7
setting 8
setting 9
setting 10
setting 11
setting 12
setting 13
then when I move my mouse over the content area containing these <li>s with the mouseOver events, all I ever see is:
updating to 4
Always 4. Any ideas?
You're creating a closure but it's still bound to the numItems variable:
function(event){ updateCurrentItem(numItems+1); }
What you should do is something like this:
(function(numItems){return function(event){ updateCurrentItem(numItems+1); }})(numItems)
Edit: I think I might have the wrong function but the same principle applies:
function(event){ updateCurrentItem(thisIndex); }
should be
(function(thisIndex)
{
return function(event){ updateCurrentItem(thisIndex); }
})(thisIndex)
