I'm working on a Greasemonkey script, and I have roughly the following:
Javascript:
var togglingLink = document.createElement("a");
$(togglingLink)
.attr('href', 'somelink')
.html('<div>foo</div><div style="display:none">bar</div>');
$(togglingLink).children().toggle();
// Then I insert it into the page.
Which makes this HTML:
<a href="somelink">
<div>foo</div>
<div style="display:none">bar</div>
</a>
The $().toggle() is only making the hidden div visible, it's not hiding the visible div. What am I missing here?
James' jsfiddle does work. But the same code in my Greasemonkey script isn't working.
Per bobek's answer, I also tried changing the divs into spans, and that didn't fix it for me.
I finally figured this out. I was actually running $().toggle(); prior to appending the element to the page. This is what was causing jQuery to not toggle as expected. Once I made it the $().toggle(); happened after appending, then it worked properly.
Having a <div> inside <a> is not valid in HTML < 5 and some browsers might not be able to work with it. Change your <div> to <span> and see if it works then.

When someone opens the page a <div> gets full width (1200px+). If I reload the page, the width is changed to the right one (550px). The browsers have their cache cleared, so this isn't a cache issue.
First visit:
After refresh:
This is a "custom HTML code" module in a Joomla 2.5 site. This is the code of divs that have their widths swapped:
<div class="art-nostyle">
<div class="custom">
<div id="script_nn_tabs54bfa417561de" class="script_nn_tabs" style="display:none;"></div>
<div id="nn_tabs_container_1____685___" class="nn_tabs_container outline_handles outline_content align_left nn_tabs_container_1_">
<div class="nn_tabs_nav" style="display: block;"></div>
At first sight I thought that the div id="nn_tabs_container_1____685___" was the problem, so I added this jQuery script at the end of the module :
var j = jQuery.noConflict();
j(document).ready(function () {
j("div[id^='nn_tabs_content_1____']" ).css("width","550px");
});
After it failed to fix it, I noticed that the problem was at the <div class="art-nostyle">. That div has no style at all! I can't use the above script for the art-nostyle div because it is added before every single module in the site. Could someone explain how it is possible when this probably isn't a cache issue - an element getting fixed width after a page refresh? I tried it on 5 different PCs that never visited the url before.
P.S. I can't recreate the problem in JSFiddle: that's why I didn't post a fiddle link.
Edit: Link of the site if someone want to check with his own eyes. Its the in middle of the index.
Edit2: I noticed that if i disable cookies the div wont change width after refresh. It will keep the full width.
If you're using jQuery, maybe you could remove the ".art-nostyle" class that may be inheriting weird styles from Joomla. You could give the one <div class="art-nostyle"> a unique ID (e.g. id="navigationLinks"), and then use this:
$(function() {
$("#navigationLinks").removeClass("art-nostyle");
$("#navigationLinks").css("width","550px");
});
You could also check to see if there's any other Javascript that references this div, because it seems weird that the problematic div would inherit the strange behavior just from HTML/CSS.
I had the same issue. However, I have found the answer. Use $(window).load() out instead of $(document).ready().
See also: window.onload vs $(document).ready()
I've tried editing this code a number of ways (using if statments and each statements) with nothing working. The idea is so simple; if a div contains this specific text, I want to change the src attribute of the image in that div only.
I can't seem to figure out what I'm missing. The code below changes all the images in all divs with that class rather than just the ones that contain the specific text. I've tried to work in 'this' but apparently don't understand how it affects the function.
$(document).ready(function(){
$('.my-content').filter(':contains("Top")').find('img').attr("src", "http://www.samplestuff.com/kids/test.png");
});
Could someone kindly point me in the right direction of what I need to change to make the script target only images in the div that contain the text instead of all div with that class because one of the div did contain that text (I think that's what triggers it; I may be off about that too).
Try this:
$(document).ready(function(){
$('.my-content:contains("Top")').find('img').attr("src", "http://www.samplestuff.com/kids/test.png");
});
See jQuery :contains docs
Edit
Actually I think your answer should work as well. Seems to work fine in this jsfiddle, can you post your markup?
$('div').filter(':contains("Top")').css("color", "red")
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>Top</div>
<div>Right</div>
<div>Bottom</div>
<div>Left</div>
I am creating a JavaScript bookmarklet to toggle the visibility of an HTML Element on a page, but it seems like just hiding the element is troublesome:
http://codepen.io/anon/pen/HtkzL
Code:
<div id="hideme">
<p>I am a div that needs to be hidden</p>
</div>
<p>I am a paragraph that doesn't need to be hid.</p>
<blockquote>
I am a blockquote that the whole world must see
</blockquote>
Click me to hide the div.
what's happening is that every the anchor link is clicked, the entire page goes blank and says "none".
When I inject the exact same code in the <a> ... </a> in a JS console, it works just fine.
Any possible fixes for the problem?
It actually is hiding the element, but it's also following your anchor right after (to nowhere). You can return false, or a falsy value. I'd wrap it in void which will return undefined, but either will work. Here's your codepen and the code: http://codepen.io/anon/pen/dsgKk
Click me to hide the div.
(This would also work, but is less clean, imo):
Click me to hide the div.
getElementById('hideme');a.style
Offhand, I'd say because the browser is confused with your variable name;
also, the code would be:
getElementById('hideme').style.display.....
I have a problem with a very simple JavaScript pop-up script.
I have this example page: http://www.onofri.org/example/example4/
At the end of this page there is a box containing some flags including the British flag that is reprsented by the #reportEng div (inside the engLink link).
What I want is that when the user clicks on this element a pop0up message will show.
So I have add to the page this simple script:
<script>
var test = document.getElementById('engLink');
test.addEventListener('click', function() {
alert('clicked');
});
</script>
I have put the script inside the body section of the page and not in the head section because this is only a test page and the final result will be put into a page of a CMS in which I do not have access to the template (so I can't put the script in the head section).
The problem is that it does not work. If I click on the English flag the page is reloaded and the pop-up not shown.
Can you help me?
Thank you,
Andrea
I went a completely different approach. The addEventListener is pretty cool, but I'm a bit OLD and I've defaulted to nasty habits. This works just fine for me.
<script>
function myExample(){
alert("BaZing! It works!");
}
</script>
And for the HTML part...
<div id="reportEng" onClick="myExample()"></div>
I also want to point out that this 'fix' is a bit taboo (see here)
You don't prevent the link from being followed, so when you click the link which has an empty href, you simply reload the current page.
There are many ways to prevent the defaul link behaviour, but here is the old school way:
<div id="reportEng"></div>
Also on a side note I don't think a div element is allowed inside an a in HTML or XHTML.
FIDDLE
You are using a <a> tag, change it to use a <div> tag, or remove <a> tag at all
You can follow this to make div clickable.
Sample Code of my error
So as you can see in the above example, next to where it says "Disclaimer Question111", there is an expand/contract link. The script works halfway, in that the text change occurs, but it does not change the display css for the div its anchored to.
Any idea why? I don't see any page errors.
The code that triggers this is in my site.js file but i pulled it out here so you can see:
$('.accordion-trigger-settings').click(function(){
var target=$(this).attr('href');
if($(target).css('display')=='none')
{
$(target).show();
$(this).text('Collapse Settings');
}
else
{
$(target).hide();
$(this).text('Expand Settings');
}
return false;
});
It applies to this block:
Expand View
<div class="padding5"></div>
<div class="accordionContent" id="accordion-season5160">
<textarea name="str_disclaimer_header5160" id="str_disclaimer_header5160"></textarea>
</div>
Using the Chrome web inspector I see you have two elements with id accordion-season5160. So, the text is changing because it applies to this but the show() method is modifying (showing/hiding) the first element with id accordion-season5160.
Make sure the id is unique.
See the image!
Hope it helps!
Actually you have two <div id="accordion-season5160"...> on the page. One of them is hidden (inside hidden <div class="hide_div">).
You can find them both using console:
document.querySelectorAll('#accordion-season5160')
You will see both of them. To see the element you can right click on it in the console and click 'Reveal in elements panel' (in Chrome)
The best way to solve this issue is to make ids unique. However you can try a quick way to solve the issue that does not require uniqueness of ids:
Replace
var target=$(this).attr('href');
with
var target=this.nextElementSibling.nextElementSibling;
