I believe the following is not possible without javascript/jquery but still wanted to confirm as I am not good in css/html/jquery.
I would like to apply certain style to an element but only when a particular url is accessed in my website.
I am using asp.net so a single aspx page template can cater to a host of urls so I cannot write the style in the html of the template.
If I write this style in a css file and include it in the template it will get applied to all urls.
I can selectively load this css file through jquery but I do not want to involve jquery into this as much as possible.
I can also use a asp.net literal control and load the css based on the url from code-behind but then addition of new urls would involve a code change. Also it sounds very messy.
Currently I am applying this through javascript/jquery as below on document.ready
if (window.location.href.toLowerCase().indexOf("/some-url/") > 0)
{
$('#some-element-id').attr('style', 'display:none');
}
But this shows the element for a split of a second before disappearing.
A solution involving jquery/javascript but resolving the above issue will also help.
I hope I was able to explain it properly.
Please let me know if any clarification is required.
It is probably showing at first because it is rendered at least a bit before the page is loaded, so it is shown until the jQuery ready() function is called on page load.
I would think the easiest fix would be to hide the element by default, then show it if it is in the URL:
#some-element-id{
display:none;
}
if (window.location.href.toLowerCase().indexOf("/some-url/") < 0)
{
$('#some-element-id').attr('style', 'display:block');
}
if #some-element-id is on a separate page then
add some-class to your element
define that class in a new .css file
only import that new .css file on the page you want the style
applied to
The URL is not part of the DOM so there’s no element to be selected by the CSS.
As you say the only way you can apply the css in a specific URL is using javascript.
The recommendation I can tell you is use addClass instead to use
.attr('style', 'display:none');
Or if you need to add a lot of css you also can include or replace the a full file like:
$('head').append('<link rel="stylesheet" href="youStilefile.css" type="text/css" />');
I hope it's helps!
the best solution is separate your css styles by codes that generated from server (independent from client).
Also you can test below code instead of $('#some-element-id').attr('style', 'display:block');
$('#some-element-id').hide();
and please insure that your jq lib imported successfully.

I am attempting to write a small script which will look at page URL and, based on what URL it sees, add a new class to an HTML element. More specifically, on this page:
http://pamaphilly.wpengine.com/volunteer/
I'm going to add a class for the active URL which will add an arrow marker to the appropriate left hand nav marker. I have tried this strategy: jQuery add class based on page URL and, when I used the script on a dummy page, it works fine. But when I try adding it to the Wordpress Template, nothing happens. I've tried adding the script at the bottom of the template file and just (as a test) embedding it in the php template. I'm guessing my failure relates to a Wordpress issues (probably a failure of knowledge on how to do this) but I would appreciate any guidance.
Thanks.
You need to include .slick before you can use it. (before script.js + in the same way you include your script.js file)
Why not do this with CSS and WordPress directly, and skip JavaScript?
You can use WordPress's body_class() function to dynamically add a class to the <body> of your page. Using CSS, you can then target your appropriate .volunteer .sidebar-member li via CSS.
I am using a python library to convert HTML page into PDF.
It does it correctly, except it only handles inline styling. It does not reflect the styling applied to DOM elements using external style sheets.
So, as a solution I am thinking of adding those CSS styling from all the external CSS stylesheets into the head tag of the html file and then send it to get converted into pdf.
But, I am not sure how? Can anyone give me any ideas or atleast suggestion on how to go around fixing that? Or, if they know a better solution.
Much appreciate
Is the python running outside or client-side? You can examine the solution here # http://www.xportability.com/XEPOnline/FOTestSuite.html. While this does a lot more, you can reach through that page to the included Javascript. Look for flattenstyle.js for inspiration.
Because our handling is different, we actually copy a selected div element to another hidden div and "flatten" the style by extracting styles we want. What you could do is run such a javascript on page load and save out the div and not destroy it, then you have most all the print styling in the HTML.
I have an image and i want, once i click it, that a particular html page is displayed into a specific div. I found several answer yet, but none of them seems to work.
I'm thinking something simple with jquery, like the answer given here: display html file in a div
What's your solution ?
Thanks in advance.
EDIT1
I want to load an internal html page ( not an external page from another webiste ) by clicking an image.
This is the code i used taking example from the answer on the link above.
<script type="text/javascript">$(document).ready(function(){$("mainscreen").load("/home/dontrythisathome/Programmazione/HTML/Progetto-Corso-Inglese/Misc/FILE/HTML/ChiSiamo.html");}</script>
"mainscreen" is the final div when i want to display the html page.
Inside the function .load() there is the path of the html page.
But no html page is displayed into the div.
EDIT2: I found the silly mistake. I use this structure: when the correct position of the elements is . I could remove also the element but i'm using CSS and i'm more comfortable to place elements than using tag options instead. Thanks for all your replies. Tomorrow i'll see if the code with jquery works.
I think your Problem is, that when you load another website using .load().
All the other websites CSS/JavaScript gets loaded and yours gets overwritten.
Could you tell us, what you are trying to accomplish?
Are you loading a html-page from your own website or an external url?
If you dont care for the styles that other website uses, you could do something like this:
.load("example.com/some.html #content");
This loads the url you specifies and just copys the content of the HTML-Element that corresponds to this selector into your target element. (ONLY INLINE-CSS will be applyed that way, you would need to do that styling manually)
EDIT: Thank you for updateing your question.
You are trying to load a file from your filesystem.
Add file:// in front of the path to your .html file.
NOTE: Especially when you are trying to use AJAX you should use a local website and work with relative paths! This makes it much easier to deploy the website afterwards as you do not have to rewrite all your URLs.
Here is jsFiddle
Your html code
<img class="img" src="http://www.lessons4living.com/images/penclchk.gif" width=100 height=100>
<div class="targetDiv"></div>
Your javascript
$(document).ready(function(){
$(".img").click(function(){ //capture the event and ignite your work
loadPage("http://fiddle.jshell.net/"); //call our function
});
});
function loadPage(link){
$.get(link,function(data){ //dont forget cross-browser rules.
$(".targetDiv").append(data) //appended in to your div
})
};
Or you can use .load function with link parametre.
Lets say you have the following HTML code.
<div id="mainscreen">click on the image to load html …</div>
<img id="js-image" src="http://cl.ly/image/0A1P1s3r2M0u/Bildschirmfoto%202014-05-24%20um%2021.59.23.png" />
And some JavaScript code (with jQuery).
var image = document.getElementById('js-image'),
mainscreen = document.getElementById('mainscreen');
$(image).on('click', function() {
$(mainscreen).load("http://fiddle.jshell.net/florianpircher/tmRy9/show/");
});
Demo: http://jsfiddle.net/florianpircher/6wXBu/1/
You can not use $("mainscreen") because that would select <mainscreen> and not #mainscreen. In jQuery, you need a CSS-selector (like $("#mainscreen")).
I need to have the old "resize fonts" option at the top of the site I'm building - one link that is the default size, one that makes fonts a size bigger, and one that makes them two sizes bigger. it only needs to affect some nav and body copy, so I'd like to simply make 2 extra stylesheets to just style those elements, and upon clicking one of the links, load an additional stylesheet into the header. when you click the "default" link, it will go back to the original size (with no additional stylesheets loaded).
Is there a way to do this in javascript? This is a Wordpress site.
Alternately, I could use js to add a tag to the body and target the elements that way.
What is the best way to do this?
You should just change the class of the elements. That will change their css to whatever is specified by that class in the stylesheet. Your first option is more complicated than it needs to be. If you use JQuery you can literally make this one line of code.
$("span#applicableId").each(function(){
$(this).class("theOtherClass");
});
You can dynamically add a stylesheet on the fly by using something like below:
function loadNewStyleSheet() {
var style = document.createElement('style');
style.type = 'text/css';
style.src = 'http://path/to/cssfile'
document.body.appendChild(style);
}
I would do this as an include statement in in a php tag. Then just have one php file you include on the top of each page.
php inlude info:
http://php.net/manual/en/function.include.php
then from there I bet there is some code out there you could reuse.
For example maybe this could be of some help? it is a php script that will ajust the css styling of the page and not interfer with other parts.
http://www.phpclasses.org/package/1296-PHP-Resizes-text-on-a-page-using-styles-and-sessions-.html
I guess that it is not possible to add it dynamically to head tag. Of course, you can do that, but this stylesheet won't be loaded. Maybe you should try to get it via ajax and append to a special script tag in your site. If user will choose another option, then you will load another content, clear this script tag and append new content there.
Lets say I put the following in <body>
<script src="https://gist.github.com/2059.js"> </script>
looking at that js file, the first line is:
document.write('<link rel="stylesheet" href="https://gist.github.com/stylesheets/gist/embed.css"/>')
I don't have write permission to that js file. Is it possible to dynamically swap out embed.css and swap in the href to another version of that CSS file? Can this be done such that it requires no user input - the page will load with my own CSS file and not embed.css?
The easiest option here is going to be to load your own CSS in a way that will override the Gist CSS - this is going to be much simpler than trying to dynamically change the code Gist provides. Two options for this:
Add !important to your CSS declarations.
Use the same selectors as the Gist CSS, but prefix them with another selector to make them more specific than the Gist CSS declarations, e.g. mycontentarea .gist-syntax .c
The second option is probably going to be more reliable, as long as you know a selector for an enclosing element. See a working example here (I've replaced the standard Gist string color with a nasty yellow): http://jsfiddle.net/aqGEc/
