How do i link all this images to an array, so as this links can work when i click each image slide
jQuery(document).ready(function() {
var bgImageArray = ["banner1.jpg", "banner2.jpg", "banner3.jpg"],
var links = ['http://google.com', 'http://hotmail.com', 'http://yahoo.com', 'http://kimjoyfox.com'],
base = window.location.origin + "/wp-content/themes/fbnquest/img/home/",
secs = 4;
bgImageArray.forEach(function(img){
new Image().src = base + img;
// caches images, avoiding white flash between background replacements
});
The way I understand your problem is the following :
For each time you click on one of each of the images, you want to redirect the user to one of the URLs, changing the URL each time the user click on the image.
Is it what you want ? If not, please can you precise your problem
[EDIT]
So yes,
Here is my way of solving your problem, If you don't matter, I won't give you code, obviously, you do this for training, let's do it :
Create an eventListener on click that will trigger a function called ChangeImageUrl (for example) and assign that eventListener to all the img elements
Then create a function that will detect the current URL of the image clicked, using imgElement.src ( i advice you to devide the src string using split or equivalent, that way you can directly access by index the current url )
Once you have the URL Use yourUrlArray.indexOf(currentImageSrcUrl), to catch the index of the current URL in your array, store it and increment it ( bonus if the increment value is upper than the URL array length, set it to 0 )
access the new src using yourUrlArray[newindex]
assign current img element the new src that we juste have extracted
Tell me if this answer is good for you, I hope it will
I was trying to understand what do you really want and I did something that I hope help you.
Inside of the loop you can do in this way below.
var i = new Image();
i.src = base + img;

We desperately need help with writing a small code that allows you to take the current page URL and the parameter in the href="parm" and create the link by joining the two with a slash.
The reason we need to do this is because we need relative links to the current page. The CMS system that we are working removes trailing slash from the end of URL.
Which is a problem because if you are at a page
domain.com/fruit/apple
and create a link such as href="calories" or href="./calories"
it will point to domain.com/fruit/calories
Instead, we want it to point to
domain.com/fruit/apple/calories
Which is relative to the current page.
We don't want to change the way that our CMS works, therefore, the need JS solution.
Below you can see one example of what we are trying to accomplish but this only works on one link.
link
Start JS
var x = window.location.href; // Current page URL
var link = document.getElementById("relurl"); // store the element
var curHref = link.getAttribute('href'); // Get HREF paramter
link.setAttribute('href', x + "/"+ curHref);
End JS
The idea is to build relative links every time links with id="relurl" is used.
As per previous example this link: a href="home" id="relurl" target="_blank" title="This is a relative link!">link
at this page: domain.com/fruit/apple
it should point to domain.com/fruit/apple/home
Meaning the link structure is the currentpageURL + / + href
One page may have multiple relative links.
Thanks for any help.
While you could just use relative URLs in your links (with href="./page"), it sounds like the problem is that you are using duplicate IDs (which results in invalid markup). You can test that you have valid markup with the W3C Markup Validation Service.
When you have duplicate IDs, JavaScript only applies to the first element. This can be seen in the following:
var x = window.location.href; // Current page URL
var link = document.getElementById("relurl"); // store the element
var curHref = link.getAttribute('href'); // Get HREF paramter
link.setAttribute('href', x + "/" + curHref);

NOT Working
To resolve this, you should use classes instead of IDs for your links. You can then use document.getElementsByClassName to select the elements. Remember that this returns a NodeList collection of elements, so you'll need to set the new URLs inside of a loop, as can be seen in the following:
var x = window.location.href; // Current page URL
var links = document.getElementsByClassName("relurl"); // store the elements
for (var i = 0; i < links.length; i++) {
var curHref = links[i].getAttribute('href'); // Get HREF paramter
links[i].setAttribute('href', x + "/" + curHref);
}

Hope this helps! :)
This will update all links in the current page:
const updateNode = node =>
node.href = `${window.location}/${node.href}`
document.querySelectorAll('a').forEach(updateNode)
I've tried searching for several hours but cannot find an answer that works. I want to load a different image for each day of the year.
I have some js that creates a variable based on the date function. I concatenate this with other text strings to get this variable:
photo2load = http://www.example.com/photos/pic132.jpg
How do I then get this photo to load. What is the scripting required? I'm at a total loss.
Thanks in advance.
You need to add an id attribute to your image and then onload call a function with inside something like this:
function loadMyImage(){
var img = document.getElementById("id-of-image");
img.src = photo2Load;
}
Or if you want to pass directly your variable call the function like this
loadMyImage( photo2Load);
function loadMyImage(imgUrl){
var img = document.getElementById("id-of-image");
img.src = imgUrl ;
}
I'm trying to put a string and a number together so a variable is in an image link, and so the variable formed by the string and number's value would display in the link, but instead the raw name just displays, not the variable's value.
var link1 = 'restOfLink.gif';
var myFunction = function(number){
var imgLink = 'http://i60.tinypic.com/';
var randomNumber = Math.floor((Math.random()*5)+1);
$("div").append("<img src = '"+imgLink+'link'+randomNumber+"'/>");
}
randomNumber won't always be 1 but let's just assume it is.
The link shows up as http://i60.tinypic.com/link1.gif
Any help on that? I'm trying to make an app that displays a new random image when a div is clicked. (the code above isn't all of the code, but it's enough to cover my problem)
If you wanted to create a dynamic img element with a variable as the link or part of it you could do:
//These are just example variables, you can use your own the same way.
var imgPath = '/images/blog/';
var size = '200x450';
document.createElement('img').src = imgPath + 'yourImage' + size + '.png';
JsFiddle Demo.
For your example i would suggest creating an array of links that you can access using a random number, for example:
var links = ['restOfLink.gif', 'anotherexample.png', 'yetanother.jpg'];
To select a particular image from inside the links array you need to pass it the index it occurs at, with 0 being the first.
So for example:
links[0] --> "restOfLink.gif"
links[1] --> "anotherexample.png"
links[2] --> "yetanother.jpg"
See this JsFiddle demo using this method.
You should create the link string by concatenating the different parts in Javascript, and update the img src attribute afterwards. Something like:
var bar = 3;
var linkString = "http://www.foo.com/image_number_" + bar + ".jpg";
document.getElementById("yourImgId").src = linkString;
Best.
Dont know what you want. A JSFiddle would help as suggested but here is my try at a answer:
string = "lol";
number = 1;
source = string+number;
$(".element").attr('src', source+".jpg");
You need JQuery for this though.
//Setting up the Array
var arrayImg =['http://www.whattofix.com/images/PoliticalAnimal.jpg','http://www.fubiz.net/wp-content/uploads/2013/03/Fashion-Zoo-Animals26.jpeg','http://cdn.trendhunterstatic.com/thumbs/suit-animal-art-berkley-illustrations.jpeg','http://img1.etsystatic.com/016/1/7647665/il_340x270.411173311_ojy5.jpg'];
// creating the randomizing
var random = arrayImg[Math.floor(Math.random()*arrayImg.length)];
// image source looks for the attribute, by using the variable arraying
$('img').attr('src',random);
Above is my code. I currently have javascript set up this way. The current code has the piece where images are randomly replaced from an image from the array. I want to have the code state that switch every image with a new random image, not every image with the same time. I like how it is random every time, but I also want to random for each picture.
Set up a loop to go over each image, pick a random one, and then assign to that one:
var arrayImg =['http://www.whattofix.com/images/PoliticalAnimal.jpg','http://www.fubiz.net/wp-content/uploads/2013/03/Fashion-Zoo-Animals26.jpeg','http://cdn.trendhunterstatic.com/thumbs/suit-animal-art-berkley-illustrations.jpeg','http://img1.etsystatic.com/016/1/7647665/il_340x270.411173311_ojy5.jpg'];
$("img").each(function() {
var random = arrayImg[Math.floor(Math.random()*arrayImg.length)];
$(this).attr('src',random);
});
You can use a callback function with the attr method to calculate the value for each element:
$('img').attr('src', function(){
return arrayImg[Math.floor(Math.random()*arrayImg.length)];
});
Need help! I've been looking for a solution for this seemingly simple task but can't find an exact one. Anyway, I'm trying to add custom #id to the tag based on the page's URL. The script I'm using works ok when the URLs are like these below.
- http://localhost.com/index.html
- http://localhost.com/page1.html
- http://localhost.com/page2.html
-> on this level, <body> gets ids like #index, #page1, #page2, etc...
My question is, how can I make the body #id still as #page1 or #page2 even when viewing subpages like this?
- http://localhost.com/page1/subpage1
- http://localhost.com/page2/subpage2
Here's the JS code I'm using (found online)
$(document).ready(function() {
var pathname = window.location.pathname;
var getLast = pathname.match(/.*\/(.*)$/)[1];
var truePath = getLast.replace(".html","");
if(truePath === "") {
$("body").attr("id","index");
}
else {
$("body").attr("id",truePath);
}
});
Thanks in advance!
edit: Thanks for all the replies! Basically I just want to put custom background images on every pages based on their body#id. >> js noob here.
http://localhost.com/page2/subpage2 - > my only problem is how to make the id as #page2 and not #subpage2 on this link.
Using the javascript split function might be of help here. For example (untested, but the general idea):
var url = window.location.href.replace(/http[s]?:\/\//, '').replace('.html', '');
var segments = url.split('/');
$('body').id = segments[0];
Also, you might want to consider using classes instead of ID's. This way you could assign every segment as a class...
var url = window.location.href.replace(/http[s]?:\/\//, '').replace('.html', '');
var segments = url.split('/');
for (var i = 0; i < segments.length; i++) {
$('body').addClass(segments[i]);
}
EDIT:
Glad it worked. Couple of notes if you're planning on using this for-real: If you ever have an extension besides .html that will get picked up in the class name. You can account for this by changing that replace to a regex...
var url = window.location.href.replace(/http[s]?:\/\//, '');
// Trim extension
url = url.replace(/\.(htm[l]?|asp[x]?|php|jsp)$/,'');
If there will ever be querystrings on the URL you'll want to filter those out too (this is the one regex I'm not 100% on)...
url = url.replace(/\?.+$/,'');
Also, it's a bit inefficient to have the $('body') in every for loop "around" as this causes jQuery to have to re-find the body tag. A more performant way to do this, especially if the sub folders end up 2 or 3 deep would be to find it once, then "cache" it to a variable like so..
var $body = $('body');
for ( ... ) {
$body.addClass( ...
}
Your regex is only going to select the last part of the url.
var getLast = pathname.match(/./(.)$/)[1];
You're matching anything (.*), followed by a slash, followed by anything (this time, capturing this value) and then pulling out the first match, which is the only match.
If you really want to do this (and I have my doubts, this seems like a bad idea) then you could just use window.location.pathname, since that already has the fullpath in there.
edit: You really shouldn't need to do this because the URL for the page is already a unique identifier. I can't really think of any situation where you'd need to have a unique id attribute for the body element on a page. Anytime where you're dealing with that content (either from client side javascript, or from a scraper) you should already have a unique identifier - the URL.
What are you actually trying to do?
Try the following. Basically, it sets the id to whatever folder or filename appears after the domain, but won't include a file extension.
$(document).ready(function() {
$("body").attr("id",window.location.pathname.split("/")[1].split(".")[0]);
}
You want to get the first part of the path instead of the last:
var getFirst = pathname.match(/^\/([^\/]*)/)[1];
If your pages all have a common name as in your example ("page"), you could modify your script including changing your match pattern to include that part:
var getLast = pathname.match(/\/(page\d+)\//)[1];
The above would match "page" followed by a number of digits (omitting the 'html' ending too).
