I have an iframe on which it opens a page which has three links.
I want to show the div on one of its links. Please suggest what to do.
Here is my code:
<div id="divTest" runat="server" >
this is a test div // Hide this div
</div>
<div class="inner-ca" style="width: 981px;">
<div class="main" style="width: 932px;">
<div id="page_FAQ">
To have a full view click here
<h2>Locate Us</h2>
<div class="box1_bot">
<div class="box1_left">
<div class="box1_right">
<div class="box1" style="border:0px;">
<iframe src="Default.aspx" width="100%" height="675" style="position: relative;"></iframe>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
Please suggest..!!!
Plain JS assuming both pages from same origin.
I gave the iFrame an ID and an onload
Working example
function assignHandler() {
var ifr = document.getElementById("iframe1");
var iframeDocument = ifr.contentDocument || ifr.contentWindow.document;
var links=iframeDocument.getElementsByTagName("a");
for (var i=0;i<links.length;i++) {
links[i].onclick=function() {
var div = parent.document.getElementById("divTest");
if (div) div.style.display=this.href.indexOf("Locker")!=-1?"block":"none";
return false; // remove when link is needed
}
}
}

I am trying to create multiple popups on one page that would appear after clicking a button corresponding to them. I currently have them under the same class, as in here:
<div>
<!-- Popup -->
<div class="popup">
<div class="popup-content">
Some text here
</div>
</div>
<!-- Button -->
<img src="button.png" class="popup-button"/>
</div>
The problem is that I am struggling to access individual elements with my javascript code. I am not sure what to replace the manual array accessing ( [0] right now ) with.
<script>
// Get the popup
var popup = document.getElementsByClassName("popup")[0];
// Get the button that opens the popup
var btn = document.getElementsByClassName("popup-button")[0];
// When the user clicks the button, open the popup (hidden by default)
btn.onclick = function() {
popup.style.display = "block";
}
</script>
Now, I could create multiple scripts and access the arrays manually for each element but of course I am trying to automate it, so that script would run depending on which button was clicked. Say, if 5th button was clicked, 5th popup appears. Thank you!
Best way to link multiple elements in Javascript is using an id through the dataset of the elements.
// Get the popup's btn list
var popupsBtn = document.getElementsByClassName("popup-btn");
// Go through the popup's btn list
for (var i = 0; i < popupsBtn.length; i++) {
// Define the onclick event on popup's btn
popupsBtn[i].onclick = function() {
// Get the popup associated to the btn with the data-popup-id
var popup = document.getElementById("popup-" + this.dataset.popupId);
// Use a class to toggle popup visible or not
popup.classList.toggle("visible");
}
}
.popup {
display: none;
}
.popup.visible {
display: block;
}
<!DOCUMENT html>
<html>
<head></head>
<body>
<div>
<div id="popup-1" class="popup">popup 1 here</div>
<img src="button.png" class="popup-btn" data-popup-id="1" />
</div>
<div>
<div id="popup-2" class="popup">popup 2 here</div>
<img src="button.png" class="popup-btn" data-popup-id="2" />
</div>

<div id="popup-3" class="popup">popup 3 here</div>
<img src="button.png" class="popup-btn" data-popup-id="3" />
</div>

Given your HTML, it would probably be easiest to just access the previous sibling of the clicked button to get to the .popup, and then change its style:
document.querySelectorAll('.popup-button').forEach(button => {
button.onclick = () => {
button.previousElementSibling.style.display = 'block';
};
});
.popup {
display: none;
}
<div>
<div class="popup">
<div class="popup-content">
Some text here1
</div>
</div>
<img src="button.png" class="popup-button" />
</div>
<div>
<div class="popup">
<div class="popup-content">
Some text here2
</div>
</div>
<img src="button.png" class="popup-button" />
</div>
<div>
<div class="popup">
<div class="popup-content">
Some text here3
</div>
</div>
<img src="button.png" class="popup-button" />
</div>
You can use other attributes to identify the button. You could not rely on the className alone.
You can use data-id attribute and pass it in the method. using this.
Depending on your HTML structure, there are multiple possibilities.
Anyway, I suggest you to use .querySelectorAll() to get your elements, and then use a .forEach() to execute your code.
I tried to use much of your code to make it work correctly.
With a parent div
// Get all the buttons that opens the popups
var btns = document.querySelectorAll(".popup-button");
btns.forEach(function(btn, index) {
// When the user clicks the button, open the popup that is in the same parent div
btn.onclick = function() {
btn.closest('div').querySelector('.popup').style.display = "block";
}
});
.popup {
display: none;
}
<div>
<div class="popup">
<div class="popup-content">Pop-up 1</div>
</div>
<img src="button.png" class="popup-button" />1
</div>
<div>
<div class="popup">
<div class="popup-content">Pop-up 2</div>
</div>
<img src="button.png" class="popup-button" />2
</div>
<div>
<div class="popup">
<div class="popup-content">Pop-up 3</div>
</div>
<img src="button.png" class="popup-button" />3
</div>
Without a parent div
// Get the popups
var popups = document.querySelectorAll(".popup");
// Get the buttons that opens the popups
var btns = document.querySelectorAll(".popup-button");
btns.forEach(function(btn, index) {
// When the user clicks the button, open the popup (hidden by default)
btn.onclick = function() {
popups[index].style.display = "block";
}
});
.popup {
display: none;
}
<div class="popup">
<div class="popup-content">Pop-up 1</div>
</div>
<img src="button.png" class="popup-button" />
<br>
<br>
<div class="popup">
<div class="popup-content">Pop-up 2</div>
</div>
<img src="button.png" class="popup-button" />
<br>
<br>
<div class="popup">
<div class="popup-content">Pop-up 3</div>
</div>
<img src="button.png" class="popup-button" />
This solution withour parent div will work even if the popups and the buttons are not next to each other. But the order (and index) of the elements need to be the same. See it here:
// Get the popups
var popups = document.querySelectorAll(".popup");
// Get the buttons that opens the popups
var btns = document.querySelectorAll(".popup-button");
btns.forEach(function(btn, index) {
// When the user clicks the button, open the popup (hidden by default)
btn.onclick = function() {
popups[index].style.display = "block";
}
});
.popup {
display: none;
}
<img src="button.png" class="popup-button" />1
<img src="button.png" class="popup-button" />2
<img src="button.png" class="popup-button" />3
<div class="popup">
<div class="popup-content">Pop-up 1</div>
</div>
<div class="popup">
<div class="popup-content">Pop-up 2</div>
</div>
<div class="popup">
<div class="popup-content">Pop-up 3</div>
</div>
Hope it helps.
I am getting unwanted class (.page) as the page loads with css property display: none, which makes the content invisible. I haven't inserted any class(.page). I have tried to undo the css property none to block via a JS but its not working. I can't figure out the problem. Its strange.
Here is the html that I actually coded:
<div class="deck-background"></div>
<div id="page">
<div id="main">
<div id="content" class="column" role="main">
<a id="main-content"></a>
<the main html content sits here>
</div>
</div>
</div>
This I am getting as the page loads. Please note two new divs with class (.page).
<div class="deck-background"></div>
<div id="page">
<div id="main">
<div id="content" class="column" role="main">
<div class="page" style="display: block;">
<a id="main-content"></a>
</div>
<div class="page" style="display: none;">
<the main html content sits here>
</div>
</div>
</div>
</div>
Here is the JS:
<script type="text/javascript">
window.onload = function() {
function showHide(id) {
var el = document.querySelectorAll('.page')
if( el && el.style.display == 'block')
el.style.display = 'none';
else
el.style.display = 'block';
}
}
</script>
Here is the JS
window.onload = function() {
var nodes = document.querySelectorAll('.page');
[].forEach.call(el, function(el){
el.style.display = "block";
});
}
I'm trying to remove the src values from all my iframes and then on click load the srcs to the ones matched by a selector.
Right now I have a block of code that empties the src of my iframes and creates a variable with the src info.
After that I'm trying to check if an iframe src is empty and if so, have a function that on click of a link will add the corresponding src values to the returned iframes.
The code is as follows, but the click part is not working.
Naturally I'm not sure about the IF part, as well, since the thing as a whole is not working.
$j=jQuery.noConflict();
var iframesa = $j('iframe');
iframesa.each(function() {
var srca = $j(this).attr('src');
$j(this).data('src', srca).attr('src', '');
});
$j(document).ready(function(){
if($j('iframe').attr('src') == '') {
$j('.evento-more').click(function() {
$j(this).next().children('iframe').attr('src', function() {
return $j(this).data('src');
});
});
}
});
The HTLM structure is something like this
<div class="evento-feed">
<div class="wrapper">
More
<div class="evento-desc">
<div class="slide-text">
<p>
<iframe src="https://www.youtube.com/embed/xxxx"></iframe>
</p>
</div>
<div class="slide-text">
<p>
<iframe src="https://www.soundcloud.com/embed/xxxx"></iframe>
</p>
</div>
</div>
</div>
</div>
<div class="evento-feed">
<div class="wrapper">
More
<div class="evento-desc">
<div class="slide-text">
<p>
<iframe src="https://www.mixcloud.com/embed/xxxx"></iframe>
</p>
</div>
</div>
</div>
</div>
And so on. The whole .evento-feed block gets repeated a few more times, although the content may vary
Is there anyone that can help me?
I have a page in which there is an anchor tag: jump to div2.
This anchor tag opens tut.html, which has a div with id=div2:
<div class="container">
<div class="row">
<div class="col-lg-8 col-lg-offset-2 col-md-10 col-md-offset-1">
<div id="div1">
--some content--
</div>
<div id="div2" style="display:none;">
--some content--
</div>
</div>
</div>
</div>
By default, the contents of div2 are hidden. How can I display or fade in its contents when a user clicks on a hyperlink in another page?
You can easily check the hash that is passed in and use that to display the appropriate block:
window.onload = function(){
var element = document.querySelector(location.hash);
if(element) element.style.display = "block";
}
your href link should not link to the page, just to the anchor :
<a class="myButton" href="#div2">link</a>
<div class="container">
<div class="row">
<div class="col-lg-8 col-lg-offset-2 col-md-10 col-md-offset-1">
<div id="div1">
--some content--
</div>
<div id="div2" style="display:none;">
--some content--
</div>
</div>
</div>
</div>
Using jQuery, you should have a function in the bottom of your document which would handle your click like this :
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"> </script>
<script>
$(function () {
$('a.myButton').on('click', function(event){
event.preventDefault();
$('div2').fadeIn('slow');
return false;
})
});
</script>
If the link goes to a new page:
link
On the bottom of the new page 'tut.html' :
<script>
$(function () {
var hash = window.location.hash;
if(hash == '#div2') $(hash).fadeIn('slow');
});
</script>

All I want to do is have a link on the same page that activates the reviews tab (id="reviews") and is also known as the body2.
all I have so far for my link is:
Reviews
Help. My brain hurts...
You just need to set the link up so that it doesn't take the user to a new page, and then setup a click event to open the tab up. Example:
HTML:
<a href='javascript:void(0);' id='reviewLink'>Review Tab</a>
JavaScript:
$('#reviewLink').click(function() {
$('.shortcode_tab_item_body').css({display:'none'});
$('.body2').css({display:'none'});
});
