javascript css without frameworks - javascript

I want to build a left sidebar that opens content in the right div when you click on a link without using a framework such as jquery.
Can you point me to a resource for this. I haven't been able to find a decent resource in Dynamic Drive or Google.
Also, I need resources to build other javascript and css tools without using frameworks.
Thanks in advance for your help.

For the left opening content in the right, you can set the left links to change the css of the right containers so they can be opened, something like:
<a rel="leftlink" onclick="openContent('content-2')>LInk 2</a>
<div id="content-2" class="visibility: hidden">I am a second right content</div>
And the js function should be:
function openContent(el_id) {
document.getElementById(el_id).style.visibility = "visible";
}
Once again, you will spend less time (and consequently less money) using a framework such as jQuery...

I'm assuming you want to have an iframe on the right and a left div with links that affect the iFrame?
To do this, you only have to change the "src" attribute of an iFrame element.
example:
var iFrameElement = document.getElementsByTagName('iframe')[0];
iFrameElement.setAttribute("src",new_page_source);
You would have to attach events to the links, and those events to change the attribute of the iFrameElement.

How do I use JQuery to wrap a specific image (located in the header) in an anchor tag?

I'm trying to use tag manager to inject jquery on a site in order to make an image in the header link to a specific page on the site. The code is working almost completely across the board, but not 100% (seems odd to me).
The image:
<img class="img-responsive margin-auto" src="/assets/misc/12345/image.png" alt="example" aria-label="example">
The JQuery:
<script type="text/javascript" id="img-link">
$(document).ready(function() {
$("img[src*='image.png']").wrap("<a href='example.com/image-related-page.html'></a>");
});
</script>
The image is a direct child of a div for mobile screen sizes and a list item for desktop screens (dealing with website platform here, which is the reason for tag manager.) what am I doing wrong?
Edit: the image is not clickable after the first visit to a certain page of the site (but works as expected on all other pages). unfortunately, due to me having to do this as a workaround the platform that this website is on, a minimal, complete, and verifiable example isn't really feasible.
If I understand what you are trying to do correctly it is to append an image to an anchor tag. You should give the anchor tag an Id: <a id="someId" href='example.com/image-related-page.html'></a> set a variable var img = $("<img>"); img.attr("src", "image.png"); and then with jQuery you could say $("#someId").append(img)
Try this:
$("img[src$='image.png']").wrap("<a href='example.com/image-related-page.html'></a>");
replaced * with $ according to Attribute Ends With Selector [name$=”value”]

jQuery UI Dialog: Dialog Element Disappearing from the DOM

I'm working on a project and I am attempting to create a modal dialog "pop-up" to capture data in a form. I haven't worked with jQuery UI's Dialog widget previously, but I've worked with others and it seemed straight forward.
I created the following very simple code snippet to test as I went along:
<div class="app-email">
<div>
<a href="#"
class="app-email-opener">
Click to add or edit your e-mail settings.
</a>
</div>
<div class="app-email-modal">
Oh, Hai.
</div>
</div>
$('.content').on({
click: function () {
console.log('I was totes clicked.');
var parent = $(this).parents('.app-email');
console.log(parent);
var target = parent.find('.app-email-modal');
console.log(target);
$(target).dialog('open');
}
}, '.app-email-opener');
$('.app-email-modal').dialog({
autoOpen: false,
modal: true,
show: false
});
For reference: the class 'content' is a higher level block to catch delegated events without having to go all the way up the DOM.
The issue I'm running into is that the div with class="app-email-modal" seems to flash onto the page and then disappear from the DOM completely. jQuery, therefore, isn't able to find it and do anything because at that point it simply doesn't exist.
The overall project is in ASP.NET MVC 4, using Visual Studio 2013.
Any information would be greatly appreciated.
So, finally discovered what's happening via this previously answered question:
Jquery Dialog - div disappears after initialization
//EDIT
For any possible future usefuless -
What was happening was that jQuery UI will move any DOM elements specified as Dialogs to the bottom of the page, rather than keep them in the location specified in the HTML markup. So, in my case, I was looking for things by class, but only within the scope of the app-email-openers parent app-email div.
To remedy this, I used templating (in my case, Razor) to add unique ids to each app-email-modal div, and added a data- attribute to associate the link with the specific unique id. This way they jQuery UI can move the elements as it sees fit, but there still easily accessible.
//END EDIT
I feel like that functionality should be better spelled out in the documentation. Even their own example doesn't operate like this.
Corollary: I attempted to use the appendTo option to have the DOM elements not be shifted to the bottom of the page, but they're still moved to the bottom. So, there's that.

Static content in website

I've got a website and I'd like to make a part of it static. What happens is that the header, the menu bar and the footer are consistent in every page. I'd like to have them always loaded and when I click the menu button, it will only reload what is the body of the site.
Is there a simple chunck of code that can early achieve this? Something in js or ajax? I'm sorry but I don't have enough experience in these languages to accomplish something on my own. I've already tried to check jQuery library but it's still pretty confusing to me.
Thank you.
I think you don't even need Ajax or css!! Just use iFrames!! They are awesome, what happens is that u only design one page as the holder of your static content (Header-Menu ...) and put one iFrame in there as a place holder for any page you want to load in it, u should use proper css code to place the iFrame where you want, now, for every link in your menu, just set the "target" attribute equal to your iFrame's name and all the links will be loaded in that iFrame and your page won't be reloaded with every link click... I'll be back with some code...
Just add in every page a div container with ID for header, menubar and footer and just load it with this:
$(document).ready(function(){
$('#header').load('header.html');
$('#menubar').load('menubar.html');
$('#footer').load('footer.html');
});
Just make sure that the html files don't have html, head or body tags within, only the HTML-Code you would write inside the div. It's just like the include function in PHP.
EDIT:
For easy and simple implementation store the code above inside a .js file (e.g. include.js) and add this inside every head just below the include of all other scripts of your html files:
<script type="text/javascript" src="include.js"></script>
EDIT2:
Another solution ist to load the content of the page instead of the header, menubar, footer.
Here you take the same specifications (no html, body, etc. tags inside your content html files)
Name your content div e.g. <div id="content"></div>
Your navbar for example:
<div id="navbar">
Content1
Content2
</div>
JavaScript Code:
$(document).ready(function() {
//Click on a link that's child of the navbar
$('#navbar > a').click(function() {
//Get the html file (e.g. content1.html)
var file = $(this).attr('href');
//Load this file into the #content
$('#content').load(file);
return false;
});
});
You should consider the use of Server Side Included : http://httpd.apache.org/docs/current/howto/ssi.html
It's not quite easy to understand (as it refer to apache configuration), but this is a really great solution.
In a nutshell, you include parts of html code in you main page :
<!--#include virtual="/footer.html" -->
You won't have to use or understand all JQuery Framewol, user agent won't have to parse (if they are able to !) Javascript.
This is a pretty good replacement of PHP / ASP / Java for this kind of purpose.
You could use ajax to request the body of each page. But this is only one possibility - there are many. An other approach could be to create you page content using a script language (php, perl) serverside and employ a function there which adds footer, header and anything else to each page.
If you have an idea of Jquery then use click event on menu links to load the page in a div like the following syntax may help you.
$(document).ready(function(){
$("a.menu").click(function(){
$("#bodyContent").load("http://abc.com/your-linked-page.html");
});
});
To load the url dynamically use the following code:
In your menu bar the link looks like:
Home
In your Jquery code:
$(document).ready(function(){
$("a.menu").click(function(){
url = $(this).attr("title"); // here url is just a variable
$("#bodyContent").load(url);
});
});
Step 1: Add Jquery file into your html page.
Step 2: Use the above jquery code and change your menu link to the new what i said here.
Step 3: If you done it correctly, It will work for you.
How about a traditional iframe?
In your menu:
<a target="body" href="URL_to_your_Menu1_page">Menu1</a>
and then further in the document:
<iframe name="body" src="URL_to_homepage"></iframe>
You may use frameset and frames and organize you pages accordingly. So, frames containing menus can always be at display and while displaying contents on click of menu u may set target to frame in which you would like to load the contents.

changing dynamically the "onlink" id in css

I made a navigation bar as tabs in my website, and I used the onlink identity to specify the current tab with certain characteristics. My problem is that when I change tabs, I don't know how to make the previous tab id set as none and the current one set as onlink.
Here's the navigation bar code:
<div id="indNavBar">
<div id="indHolder">
<ul>
<li><a onclick="DisplayDIV('IndPage');HideDIV('DoubleInd')" id="onlink">Single Indicator</a></li>
<li><a onclick="DisplayDIV('DoubleInd');HideDIV('IndPage');">Double Indicators</a></li>
</ul>
</div>
</div>
There's a simple ways but it's somehow stupid, which is to make each current tab as a whole page and when I click another tab, it's just given the url of clicked tab which goes to the page with specified onlink id, but this requires reloading the whole page that's why I'm seeking a better solution.
You can get the control being clicked by passing this in javascript method
onclick="DisplayDIV('IndPage', this);
function DisplayDIV(IndPage, sourceObj)
{
alert(sourceObj.id);
}
Are you ok do use the jQuery Library?
If so you can avoid putting inline javascript into your html and use toggleClass http://api.jquery.com/toggleClass/
You are trying to use HTML ids in the wrong way.
Ids are unique identifiers for HTML tags. They should not change at runtime.
Instead, apply CSS classes to the tab you want to be visible.
CSS
.hide {display:none;}
Javascript
var indpage = document.getElementById("IndPage");
if (!indpage.classList.contains("hide")) {
indpage.classList.add("hide");
}
Then your HTML at runtime will change to
<div id="IndPage" class="hide">...</div>
This is the standard approach.
And you can do much more with this idea.
I agree that making a tab a whole page is not a good idea. You can use javascript to apply CSS classes to hide and remove that class to show again.
Its also a good idea to learn how to separate your javascript from your HTML. Please read some more tutorials on this. One for instance: Unobtrusive Javascript
Here is a jquery way to do it: http://jsfiddle.net/surendraVsingh/HyAhL/
$('#indHolder a').click(function(){
$(this).attr('id', 'onlink');
$(this).parent().siblings().find('a').removeAttr('id');
});​
I took hints from the answers above and it worked as the following:
function putOnlink(x){
document.getElementById('onlink').id = "none";
$(x).attr('id','onlink');
}
and the tabs code is:
<div id="indNavBar">
<div id="indHolder">
<ul>
<li><a onclick="DisplayDIV('IndPage');HideDIV('DoubleInd');putOnlink(this);" id="onlink">Single Indicator</a></li>
<li><a onclick="DisplayDIV('DoubleInd');HideDIV('IndPage');putOnlink(this);document.getElementById('onlink').id='none'">Double Indicators</a></li>
</ul>
</div>
</div>
I just wanna not that in the second link I had to change the id of the first link twice because it didn't work once, maybe cause its id is set in the tag not just when clicked.

Show/Hide On Click

I have one area of space and two body's of text to show. I have two "hyperlinks" above this area and would like to use those to show/hide the text below. Upon first loading the page, nothing will be showing except for the two links. When you click one link it shows the body of text. When you click the other link it will hide the previous body of text and show the new text. There are only two hyperlinks, but I would like for the user to be able to toggle back and forth at their convenience. Is this possible? Previously I was using javascript to unhide the text because they were in two different areas. I am not too experienced with writing code. I have found some other answers on this topic useful but most of them use buttons and on click listeners. Is there a way to do this using a hyperlink? Code examples are very much appreciated!
You could define a class in CSS that says "Don't show the text in here" then use JS from the hyperlink click to switch the class of the element?
so your html will contain:
<a onclick="showText('text1','text2')" href="javascript:void(0);">Show Text 1</a>
<div id="text1" class="hide"> text1 </div>
<a onclick="showText('text2','text1')" href="javascript:void(0);">Show Text 2</a>
<div id="text2" class="hide"> text2 </div>
Your CSS would contain:
div.hide { display:none; [your properties]; }
div.show { [your properties]; }
and the your JS would look something like this:
function showText(show,hide)
{
document.getElementById(show).className = "show";
document.getElementById(hide).className = "hide";
}
Does this help at all?
<a id="myLink" href="javascript:void(0)" onclick="javascript:myLinkButtonClick();"> </a>
in javascript you can do this if you use jQuery:
function myLinkButtonClick()
{
$("#myDiv").hide();
}
or
function myLinkButtonClick()
{
$("#myDiv").show();
}
Alternatively you can do .toggle
function myLinkButtonClick()
{
$("#myDiv").toggle();
}
Many will agree that using anchor tags to execute Javascript (and do nothing else) is a little on the messy side, since, among other things, it generates a hash tag in the address bar which can confuse users. That isn't to say that they don't have their place in JS execution.
It is very possible to achieve this however. Here is one possible solution:
Link1
Link2
<div id="div1">Text1</div>
<div id="div2" style="display:none;">Text2</div>
<script>
var currentDiv = document.getElementById("div1");
function show(divID) {
var div = document.getElementById(divID);
currentDiv.style.display = "none";
div.style.display = "block";
currentDiv = div;
}
</script>
The script tag defines a variable and a function: currentDiv, which references the currently displayed div element and a show function, which is used for hiding the currently displayed div and showing a new one.
The anchor tags at the top, when clicked, call the show function, replacing the currently shown element with the one the anchor tag specifies.
In order to get elements to show/hide, the code changes the element's CSS display attribute. A value of block shows the div element, and a value of none hides it. The second div has its display property set to none when the page loads. Javascript will change this attribute when a link is clicked.
No, you do not need JQuery to do this, but it can help.
There's a nice jQuery script that does something along these lines, have a look to see if it's any good for you:
http://api.jquery.com/slideToggle/
This is possible, but a more user friendly way of doing this would be with something like jquery tabs. It's very easy to do it with jquery UI's tab feature, it's all HTML markup with a script that just runs .tabs(); as the function on the ID of the tab element.
Here is a link: Jquery Tabs
Tabs would be the best way to do this. There's plenty of tutorials around for jQuery tabs - here's a fairly basic one which outlines the concepts pretty well, and here's a more advanced one (which goes into using CSS to generate rounded corners on tabs).
