Note: I am not a developer. More of a hobbyist (read n00b).
I have tried searching for an answer to this but so far have not found anything that provides an answer to this specific scenario.
I know this is relatively basic but, I am trying to create a page with three hidden elements that are revealed either after a time delay or a mouse click. What I am struggling with is getting all three elements to run on the same page.
Required:
Element 1: Hidden image to be revealed 10 seconds after page load
Element 2: Hidden div to be revealed 10 minutes after page load
Element 3: Button image inside element 2, when clicked reveals another hidden div
I am using the following setTimeout function to reveal element 1, but I can't get a second setTimeout command to run after this.
<script language="javascript" type="text/javascript">
var pop=10;
function showIt() {
document.getElementById("hid").style.display = "block";
}
setTimeout(showIt, 10000);
</script>
I tried repeating this code for the second element changing the Element ID to "hid2" but it will not run. Do I need to use a cleartimeout function to end the first settimeout?
I then need some code for element 3 to run on a mouse click after element 2.
Getting all three bits of JS to play nicely together seems to be beyond me.
Your help would be much appreciated!
I believe this is what you're asking for.
<img id="hid" src="img/darkred.jpg" style="width: 20px; display: none;"/>
<div id="hid2" style="display: none;">div 2
<input type="button" value="show div3"/>
</div>
<div id="hid3" style="display: none;">div 3</div>
function showIt(hid) {
document.getElementById(hid).style.display = "block";
}
function revealEl(id, delay){
setTimeout(function(){
showIt(id);
}, delay);
}
revealEl("hid", 4000);
revealEl("hid2", 6000);
$("#hid2 input"").on("click", function(){
showIt("hid3");
});

Not sure how to approach the task or what specific code would work but am thinking a nested function might do it.I just don't know exactly how to properly implement it.
I can create the button in HTML and have it display the picture but am unsure how to code/incorporate the setDuration (I'm assuming here) function part. Being somewhat new to JS so looking for best practices for a hopefully simple task. Sincerely appreciate any assistance/input!
you can use on click event to show picture and hide it using setTimeout.
HTML:
<!-- button -->
<button id="btnId">Hey Click me!</button>
<!-- image to hide and show -->
<img src="img_path_here" alt="" id="imageID" style="display: none" />
Javascript
// add click event to button
document.getElementById("btnId").addEventListener('click', function() {
//show image
document.getElementById('imageID').style.display='block';
// hide image after 1 sec.
setTimeout(function() {
document.getElementById('imageID').style.display='none';
}, 1000);
});
Give your image an id and use:
setTimeout(()=>{
document.getElementById("id").remove();
},200)
You can use setTimeout to time when your picture will disappear. It will something like this.
function displayPicture() {
// code that displays picture
image.display = "block";
setTimeout(()=> {
// code that hides the picture
image.display = "none";
// the picture will disappear in 5 seconds
}, 5000);
}
I have a website where there is a side menu filled with links. On top of that are some Next and Prev buttons for the user to switch between the menus of links.
I want to change this so that the menu will automatically change after x amount of time.
I thought something like this would do it:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
function delayer(){
window.location = "http://www.google.com" }
</script>
</head>
<body onLoad="setTimeout('delayer()', 1000)">
</body>
</html>
Basically, instead of opening google, I want the page to run the "Next" button which is represented by:
<div class="navBtns mar9 s3">
<span></span>
<span></span>
</div>
Any idea on how to do this? Thanks!!
If you'd like to "click" the next button, then you can do that programatically with JS.
var nextbutton = document.getElementsByClassName('next');
nextbutton.click();
Getting element by class like that only works on post-IE8 browsers.
<span></span>
This hyperlink does nothing by itself. Somewhere on the site, there is a javascript function bound to the click event of this link. You need to either trigger a click event on the link, or call the javascript directly.
Without seeing the rest of the javascript / knowing what frameworks are in use on the page, it's impossible to give a more precise answer.
-- EDIT --
Based on your comment, you may be able to do something along these lines:
<script type="text/javascript">
setTimeout(function() {
$('#page_HOME .slider .next').click();
}, 1000);
</script>
As long as those hyperlinks are contained inside the slider element, the above code will trigger a change in your side menu after 1000 milliseconds
You could find the HREF of the link you want based on the class name of the link, using plain old JS.
window.location = document.querySelector(<link class name>).getAttribute("href");
This will redirect the browser to whatever the href attribute is set to.
If you wanted to keep a function like you have, you could use this:
function delay(link, time) {
setTimeout(function() {
window.location = document.querySelector("." + linkClass).getAttribute("href");
}, time);
}
Then to use it, just say:
delay("next", 5000); // go to the href of the link with the class "next" after 5 seconds.
I have a little jQuery function in my Asp.Net MasterPage that fades an image out after 3 seconds. It works fine, but I'm having difficulty getting it to fade back in. I've tried several things as I'm new using jQuery, and I know there's something I'm doing or not doing. I can't put my finger on it. Here's what I have:
<script src="/Scripts/jquery-2.1.1.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function (){
setTimeout(function (){
$('#Image1').fadeOut('slow', function(){
$('#Image1').remove();
});
}, 3000);
});
var fadeBack = function () {
$('#Image1').fadeIn();
};
fadeBack();
</script>
Like I said, it fades out with no problem, but I cannot find the right code structure to bring it back in. I'm thinking maybe an If statement block about the opacity is needed?
The real trick is that I want alternate images in 3 boxes I have as seen here:
I have about 12 images total, and just want them to fade one image out, and bring another in. Being more specific, I mean the following:
Column (1): Image1.FadeOut(); Image2.FadeIn(); Image2.FadeOut(); Image3.FadeIn(), and etc.
So for now, I just need help with how to do this in Column One, and I'll see if can string something together to make the other Columns 2 and 3 follow up. The timing would be 3 second for each.
Lastly, could I use an array to store other images which aren't in the Column One box already and call them into the slideshow fade sequence? I appreciate you help for this knowledge, so I can lock this in mind. Thanks.
Use this code, it will hide the image after 3 seconds and after that 1 sec, it will show image back.
$(document).ready(function (){
setTimeout(function (){
$('#Image1').fadeOut('slow');
}, 3000);
setTimeout(function (){
$('#Image1').fadeIn('slow');
}, 4000);
});
if you want like a slideshow use this code
<div class="yourimg_container">
<img src="http://localhost/app/img/off.png" id="Image1"/>
</div>
/* make an array containing your images path (you can fetch images from database using asp.net/php query)*/
var ss= ["http://localhost/app/img/off.png",
"http://localhost/app/img/on.png",
"http://localhost/app/img/slider.png"];
window.setInterval(function(){
slideshow();
}, 3000);
function slideshow(){
var im=$("#Image1").attr("src");
for(i=0;i<ss.length;i++){
if(ss[i]==im){
if(i==ss.length-1) $('#Image1').attr("src",ss[0]);
else $('#Image1').attr("src",ss[i+1]);
}
}
}
additionally you can use other effects like this
function slideshow(){
var im=$("#Image1").attr("src");
for(i=0;i<ss.length;i++){
if(ss[i]==im){
if(i==ss.length-1) {
$('#Image1').fadeOut(500);
$('#Image1').attr("src",ss[0]);
$('#Image1').fadeIn(700);
}
else {
$('#Image1').fadeOut(500);
$('#Image1').attr("src",ss[i+1]);
$('#Image1').fadeIn(700);
}
}
}
}
Your fadeBack() is launched immediately whereas the fadeOut has 3 sec delay. Set a timer for your fadeBack grater than 3 sec and the img will appear.
There is a function $('#Image1').remove(); Applied. It mean once fade over, the html block will be removed. Then you can't access the object. Because fade in and fade out accessing same id #Image1. So comment the line. It may work.
I am still new to javascript.
I have an application that has two buttons on the page. One is a cpu_vs_player button that displays one game and the other is a player_vs_player button that displays a different game. The problem is that all the code is located in one application.js file. There is no need to load the player_vs_player on $(document).ready(function(){}); if I were to play cpu_vs_player.
Any ideas on how I can get them to load only if I chose that game? (I am only using one route with all the information being hidden / shown based on the click).
The document.ready is nothing more than the moment after the page has rendered and the document needs to be populated with event listeners. Frankly there are multiple way of skinning this cat.
You can either do the jQuery way where you keep javascript and HTML divided:
<button id="button1">cpu_vs_player</button>
<button id="button2">player_vs_player</button>
And for JavaScript:
Assuming you have a function for each gameplay:
function cpu_vs_player() {
// start the game
}
function player_vs_player() {
// need another player
}
Add event listeners the jQuery way:
$(document).ready(function() {
$("#button1").click(function() {
cpu_vs_player();
});
$("#button1").click(function() {
player_vs_player();
});
});
OR you could use the method #Techstone shows you, though you could do it more direct. It all works though.
<button onclick="javascript:cpu_vs_player();">cpu_vs_player</button>
<button onclick="javascript:player_vs_player();">player_vs_player</button>
Adding another option you can apply
In Javascript:
var Main = {
cpu_vs_player: function() {
alert("start cpu_vs_player");
},
player_vs_player: function() {
alert("start player_vs_player");
}
}
In your HTML:
<button onclick="javascript:Main.cpu_vs_player();">cpu_vs_player</button>
<button onclick="javascript:Main.player_vs_player();">player_vs_player</button>
And yes, there is more ... ;-)
image that your two button and js definition like below
function LetsRock(Playmate) {
....
}
<input type='button' value='cpu_vs_player' id='cpu_vs_player' onclick='javascript:LetsRock(this.id);' />
<input type='button' value='player_vs_player' id='player_vs_player' onclick='javascript:LetsRock(this.id);' />
Try to use the function with parameters (i.e. 0 to cpu v/s player, 1 to player v/s player), and send from the menu page to the $(document).ready(function(){});
I'm new in javascript, now I'm trying to do that, as the title, I've a page which has a div at the top that is as big as the page with a video in it, followed by several sections like this:
<div id="first" style="height:100%; width:100%"></div>
<section id="second" style="height:100%; width:100%"></section>
<section id="third" style="height:100%; width:100%"></section>
Now I need 5 seconds after the page is loaded to scroll automatically the page to #second.
I've tried many ways but have failed and haven't found nothing that works properly.
Thanks
I'm feeling generous, so I'll just give you the code this time.
$(window).load(function () {
//normally you'd wait for document.ready, but you'd likely to want to wait
//for images to load in case they reflow the page
$('body').delay(5000) //wait 5 seconds
.animate({
//animate jQuery's custom "scrollTop" style
//grab the value as the offset of #second from the top of the page
'scrollTop': $('#second').offset().top
}, 300); //animate over 300ms, change this to however long you want it to animate for
});
Use this at the end of your codes
setTimeout(function(){window.location.hash = '#second';},5000);
Note that those height:100%; are wrong.
You could use
window.location.hash = '#second';
This will set the focus. I'll leave you to put in some work on a timer solution.
Also, I would discourage any forcing of the user to focus on a particular div. This is not a very good UX practice and can lead to chasing users off your site, especially because they may not understand why the page is scrolling up.
$(function () {
setTimeout(function () { goToSecondTab(); }, 5000);
function goToSecondTab() {
window.location.hash = '#second';
}
});
Add HTML to this line in zzzzBov's script to make it work properly in FF:
$('html, body').delay(5000) //wait 5 seconds
