Get link href and apply it to another link jQuery - javascript

I have a set of DIVs, each contains an image with an empty anchor tag wrapped around it
Image is here
I then have a 'Continue reading' link just before the div closes
Continue reading <span class="meta-nav">→</span>
Is there a way with jQuery that when the page loads, I can that the href location of the continue reading button and apply that the empty anchor wrapped around my image?
Demo: http://jsfiddle.net/2hu66/1/

It is possible, but it is not a good idea. Links created with js are not visible for google crawers. The right way of doing this is creating a real link instead of "#".
Do the things right not interesting ;).

based on your HTML, you can do this:
​$(function(){
$('.card-prod').each(function(){ //for each item
var theLink = $('a[href^="?p"]',this).attr('href'); //get the link
$('a.cardclick',this).attr({'href':theLink}); //set to img link
});
})​​

You can loop through the "continue reading" links and copy their href, perhaps like this:
​$(​"div.card-prod a:contains('Continue reading')")​​​​​​​​​​​​​​​​​​​​​​​​​​.each(function() {
var $this = $(this);
$this.closest("div.card-prod")
.find("a.cardclick")
.attr("href", $this.attr("href"));
});​

The :contains selector that I used above is not going to be the most efficient way to do it, but it works. If it were my html I'd probably give those "continue reading" anchor elements a common class and select on that. Or you could select the "meta-nav" spans and then take their parent. (Lots of options, really.)

$('.card-prod').each(function() {
var cr = $(this).find('a:last');
$(this).find('.cardclick').attr('href', cr.attr('href'));
});

How to add an id to an existing div on click in css/js?

I'm new to html/css/js and I'm working on a small project where I have a few divs with the same classnames, for example:
<div class="imgBox">
Something here...
</div>
None of them have an unique id. What I want to do is to add an id to a single div after I click on it. It would allow me to modify the selected div and make it in css fullscreen or something like that.
Do you have any ideas how to create a function in js for it?
I couldn't find a proper solution on the internet, but if I missed something, let me know.
Not entirely sure of your logic for wanting to add the IDs after the element is created, but this would add the ID attribute when you click the div.
var global_id = 1;
// click on div
$('.imgBox').on('click', function(e){
existingID = $(this).attr('id');
if (typeof existingID == 'undefined'){
$(this).attr('id', global_id);
global_id++;
}
});

Store jQuery in a variable

I've got an FAQ page I'm building. Next to the question, there is a plus sign to expand the content. On click, I've added the class active, but there are many questions, and I don't want to repeat the same jQuery snippet for each question. I've figured out how to find the parent ID but I'm having trouble storing it in an variable to reuse in the jQuery script.
What I want to be able to do:
var element = $(this).parent().parent().attr('id')
$('.expand').click(function(){
$('element .expand').toggleClass('active')
})
Is there a way to do this? I get undefined when I do this:
$('.expand').click(function(){
console.log(element)
});
You can use the find() function to locate children of a selected element:
var element = $(this).parent().parent().attr('id')
$('.expand').click(function(){
$("#" + element).find('.expand').toggleClass('active')
});
However, looking at your code, it seems like you just want to toggle the "active" class of the clicked element. If that is the case, you can do this much more simply without a variable at all:
$('.expand').click(function(){
$(this).toggleClass('active')
});

JavaScript click href without ID

I'm on a site where I would like to grab all the href links and click it. I know I could do this. document.getElementById('yourLinkID').click(); how ever, the issue is the href dosen't have an id, only a title. Can I somehow click all the href by it's title?
Accessing the document.links array would be the solution you are looking for.
From there, though, clicking one would cause the page to navigate away to its target, and the script would stop executing. If you must click them all, what you could do is loop through them, and set the target of an iframe with the link's href attribute.
You can use document.querySelectorAll() with selector a[href] to retrieve all <a> elements having href attribute set, or [href] to retrieve all elements having an href attribute set; for..of loop to iterate collection
var hrefs = document.querySelectorAll("a[href]");
for (let elem of hrefs) {
// do stuff
console.log(elem.href);
}
use querySelectorAll:
document.querySelectorAll("[title=foo]")
Which will give you an array.
iterate through the array if your goal is to click all the links.
obviously, clicking a link will redirect you to that page and will pause script execution.
a dirty solution would be to use:
selectedElement.setAttribute('target', '_blank');
where selectedElement is the link's selector.
this makes the url open in a new tab.
No idea why you would want to do this as each <a href... will be activated and after the first one it will be up to the browser to work out what happens.
var aList = document.getElementsByTagName('a');
var i, max = aList.length;
for(i=0;i<max;i++) {
aList[i].click();
}
Hello
world
You can try the following solution,This will loop through each href and Click it.
$('a[href]').each(function ()
{
$(this).trigger('click');
});

Put li attribut on a span

I am a beginner in the wonderful world of dev and I need help from you. Let me explain :
I have a menu that deploys when pressing on the burger and thus reveals three items .
On the one hand I am that when you click on an item the menu closes
And on the other hand I am cut the item to appear in the SPAN :)
$('li').click(function() { alert($(this).attr('id'));})
Thank you for your help.
DEMO JSFIDDLE
Envoy Everybody
simple as this : jsfiddle
added this
$('li').click(function() {
$('h1 + span').text( $(this).attr('id') )
$('#overlay').removeClass('open');
$('#toggle').removeClass('active');
})
also removed the class open from #overlay so after you click the li the menu closes, and removed the class active from the button so it changes from X to the hamburger lines . you can exclude these two lines if you don't need them
You successfully got the value of the id; now you just need to get the element you want to add it to, and add it.
Instead of putting the value in an alert, you'll use the value in jquery's text() function (assuming that you want the ID to be inside the <span> tag).
First, get the <span> element you want:
$('.top')
This gets all the elements with the class "top".
Now call the text() function (more info here: http://api.jquery.com/text/) on the element:
$('.top').text('your text here');
Instead of 'your text here', put the value of the ID in, like this:
$('.top').text($(this).attr('id'));

Getting ALL First links in a specific class

So I know that using "a:first" will get the first link of a page. Lets assume we have the following:
<div class="masterclass">
Link 1
Link 2
</div>
<div class="masterclass">
Link 1
Link 2
</div>
Naturally I can use the following code to get the first "a" of the class "masterclass"
$('.masterclass a:first').click(function() {
alert('yayfirstlink');
});
However I do not understand how to get the first link of every "masterclass"
You need to use find() here because your selector will find all the anchor elements with in .masterclass then filter only the very first one. But when you use .find(), it will find all the .masterclass elements first then will find the first anchor element in each of them.
$('.masterclass').find('a:first').click(function() {
alert('yayfirstlink');
});
or if you are sure that the target element will be the first child of its parent then you can use :first-child
$('.masterclass a:first-child').click(function() {
alert('yayfirstlink');
});
Try this,
var oFirstAnchor = $(".masterclass a:first-child");
$(".masterclass a:first-child") is what you are looking for.
so:
$('.masterclass a:first-child').click(function() {
alert('yayfirstlink');
});
This is how u loop through each of the masterclass and get the first link of it.
i don't know what you want to do with it though so i can only provide this
$(document).ready(function(){
var fields = $('.masterclass a:first-child');
$.each(fields, function(index, val){
alert(index);
});
});
this alerts the current links array index
http://jsfiddle.net/kBd82/6/
I would recommend using the first of type selector for this.
$('.masterclass a:first-of-type')
This way it will always select the first anchor tag in each masterclass div even if you put other things in the div later.
