First I realize ID's should be unique. But right now I can't do much about that. I have a javascript plug-in that is generating ID names and for one page it works great. The issue is in creating another page, it will start over using the same naming convention. For example:
Page 1
<ul id="1">
Page 2
<ul id="1">
So if I am trying to style ul#1 on Page 1 it will also style ul#1 on Page 2. So, any suggestions on how to separate our the two id's? This html is generated by the JS, otherwise I would just attach a class to it.
Thanks.
First, the unique ID suggestion is restricted to a page. It is perfectly fine to have multiple ID's on different pages. The best way to overcome this is to add a ID to the body.
Page1
<body id="Page1">
<ul id="1">
<li></li>
</ul>
</body>
Page2
<body id="Page2">
<ul id="1">
<li></li>
</ul>
</body>
CSS
#Page1 #1
{
//Some style for page 1, ID 1
}
#Page2 #1
{
//Some style for page 2, ID 1
}
Can you attach a class around it ? Have a div or span some other element surround your code that does the generation and assign a class to it.
I'd say you have to use different style sheets on each page if you need different styles for the same ids, but this will be a pain to maintain as you make styling changes.
Alternatively you could you assign a class to one of the page's UL tags and then create a style for that class.
First of all, the plugin is still not generating the correct ids because ids can't be numbers. To answer your question, try to figure out some parent element that might be different between the two pages probably in which case you can use CSS such as this:
#parent ul#1{
/* styles here */
}
#parent2 ul#1{
/* styles here */
}
page1:
<div id="parent">
<ul id="1">
............
page2:
<div id="parent2">
<ul id="1">
............
So you need to find out a some parent element of ul which is not common between the two pages. This is the only possibility that comes to my mind where you have no control over changing the ids or replacing them with classes since they are being generated by the plugin.
You need something to distinguish them if you want them styled separately. If you cannot modify those tag you could probably use some parent container like:
<div id="parent1">
<ul id="id1" />
</div>
<div id="parent2">
<ul id="id1" />
</div>
and then:
#parent1 ul {
...
}
#parent2 ul {
...
}
Also notice that an id cannot start with a number as in your case. You should probably consider switching/modifying this plugin.
One thing I commonly do is attach a class to the body for each page. <body class="home_section"> and then you could style based on that class .home_section ul#1 {}.
Also, IDs must begin with a letter.

I am fairly new to using html and css beyond the minor basics. I am trying to make a loading page for a website and can't seem to find an example for my exact case.
Here is the html I want to show only on loading:
<section id="hero">
<div id="mast">
<h1><img src="data:image/image/gif;base64/=" alt="bus" /></h1>
<h2>Let's Travel</h2>
</div>
<div class="arrow"><a data-scroll data-speed="750" data-easing="easeInOutCubic" data-url="false" href="#navigation"><i class="fa fa-angle-down"></i></a></div>
</section>
I saw an example on stackoverflow loading class of html like this:
<script src="js/jquery-1.12.3.min"></script>
<script type="text/javascript">
$(window).load(function() {
$(".classname").fadeOut("slow");
})
</script>
Is there away to have a section load by the id instead of just a css class?
In jQuery, you can use CSS style selectors. So, if I want to select all elements from a class I can do $('.classname'), if I want to select an element by id: $('#idname'), if I want to select all <p> tags, I could do $('p'). Hell, I could select all <bold> tags within <p> tags by doing $('p > bold').
Anyway, I'd take a look at how CSS selectors work, and then you'll now how to select anything in jQuery: https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Getting_started/Selectors
In your case, I'm guessing you want to use $('#hero').fadeOut()
I am very new to jQuery and not entirely sure what I'm doing. Will try my best to explain the problem I'm facing.
I'm trying to lock some content on a landing page until a user shares the link using FB, Twitter, LinkedIN or G+. The first version of the script I wrote (which worked fine) ran like this:
<head>
<script type="text/javascript">
...
$(document).ready(function()
{
$('.class').click(clearroadblock());
buildroadblock();
}
</script>
<style>
.class
{
[css stuff]
}
</style>
</head>
<body>
<div id="something">
<ul>
<li> Link1 </li>
<li> Link2 </li>
</ul>
</div>
</body>
The problem I'm now facing is changing out this code to replace the list elements with social share buttons. As they are no longer under .class, but classes like fb-share-button and twitter-share-button. Please help me understand what I need to modify to accommodate this? PS: This is not a Wordpress site.
function clearroadblock()
{
$('#roadblockdiv').css('display', 'none');
$('#roadblockBkg').css('display','none');
}
This is the way I'm clearing the overlay once a click is detected, BTW.
Can I wrap the social buttons in divs, assign them IDs and use those IDs to trigger the click like below?
<div id="Button">
Tweet
</div>
$('#Button').click(clearroadblock());
You can have multiple classes on an element by separating them with a space. Try the following:
class="class fb-share-button"
Your jquery will still work off the "class" class. I would recommend you change this name to something more meaningful though. Your css can target the "class" for general styles, but you can also target fb and twitter separately.
Update
I decided to create a quick JSFiddle for this.
Some of the styles etc won't be the same as what you're doing, but the problem is resolved. I've created a div with id main that contains the content that you want to hide. There's an absolutely positioned div over the top of this, this is the roadblock. The javascript is showing the roadblock (assuming that's what you wanted to do with buildroadblock()).
On click of a link in the ul with id socialMedia we call clearroadblock. Notice the lack of parenthesis. This hides the roadblock.
This isn't a great way of preventing someone from seeing information, you might want to think about pulling the content down from the server when the action is performed, however, I think this answers your question.
Suppose i have this structure of elements:
<div class="parent">
<div class="something1">
<div class="something2">
<div class="something3">
<div class="something4"></div>
</div>
</div>
</div>
</div>
And code like this:
$(".something4").click(function(){
//i could do it like this...
$(this).parent().parent().parent().parent().parent();
});
But that seems to be stupid, is there a better way to do this?
also i can't just say $(.parent) because there are many divs like this with class parent in my page.
Use .closest(selector). This gets the first element that matches the selector, beginning at the current element and progressing up through the DOM tree.
$('.something4').click(function() {
$(this).closest('.parent');
});
Use .closest():
$('.something4').click(function() {
$(this).closest('.parent');
});
I think you should try this
$(this).parents(".parent");
But I don't know where on the page are the other divs with this class :)
You could always use .parentNode (standard JavaScript). It's generally a bad idea to use class names that coincide with function/variable names from the library you're using (this goes for any language). Making your class names more unique is a better approach (for instance, "scparent" instead of "parent", if the name of your application was "Super Calculator" or something). This avoids conflicts such as the one you're describing.
I would caution using .closest(), simply because you may create a function like this:
function getParentElem() {
return $(this).closest('div');
}
And it would grab the parent div's in your code just fine, but if down the road you add a table for displaying data, and you run the function through a child element of the table, you will have to create another implementation that selects the table element, because that's what you now want:
<div id="tableParent">
<table id="dataTable">
<tr id="target1">
<td>Some data.</td>
</tr>
</table>
</div>
By using your function getParentElem() on the tr element, you'll end up grabbing the div with id="tableParent", rather than the actual parent, which is the table element. So, unless you've delineated your parent classes appropriately all the way through your code (which can be a pain and isn't always efficient), you may run into problems. Especially if at any point you're creating elements programmatically, or reading in data from another 3rd-party library or script.
Not saying it's not good to use .closest()... just pointing out a possible "gotcha".
i would suggest adding to the div parent an id like 'parent_1' etc. and in every son you keep the id in the rel attr
<div id="parent_1" class="parent">
<div rel="1" class="something1">
<div rel="1" class="something2">
<div rel="1" class="something3">
<div rel="1" class="something4"></div>
</div>
</div>
</div>
</div>
$(".something4").click(function(){
//i could do it like this...
$('#parent_' + $(this).attr('rel'));
});
Here is the portion of HTML in question as well Javascript related to it:
HTML first:
<div id="menu">
<ul>
<li>click</li>
</ul>
</div>
Javascript goes:
$("#menu a").click(function(){
var link=encodeURI($(this).attr("href"));
$("#divtobeloadedwith").load(link);
return false;
});
content.html structure:
<div id="wrapper">
<div id="diviwant">stuff</div>
<div id="dividontwant">stuff</div>
</div>
Upon clicking on link it loads all the content instead only specific div.
Fundamentally the problem is that you want two different things:
When running without Javascript, you want to use the link content.html#diviwant, as that will load the page content.html and then jump to the element with the ID diviwant.
When running with Javascript, you want to pass content.html #diviwant to jQuery's load() method, as that tells jQuery to load only the fragment with the id diviwant from the target page.
I'd probably use content.html#diviwant as the link, as you've got, then interpret that in the jQuery like this:
$("#divtobeloadedwith").load(link.replace('#', ' #'));
...to add the necessary space for the load().
You need to remove the space between content.html and #diviwant in the href of your link.
<li>click</li>
You also need to make sure that "divtobeloaded" exists.
<div id="menu">
<ul>
<li>click</li>
</ul>
</div>
<div id="divtobeloaded"></div>
I've been having nothing but problems with this script for a simple hide/show gallery of testimonials.
I think the java is somewhat self explanatory...
When the page loads, I tell it to show the first testimonial in the line up (as the css is display:none) and gives it a selected class name. Works fine in across the board.
On click I want it to remove the selected class place it to another, and then hide the first testimonial and pull up a corresponding one. Except all that happens here is the first testimonial disappears (hide) and the selected class is added.
<script type="text/javascript">
$(document).ready(function(){
$(".testimonial:first").show();
$("li.testID:first").addClass("selectedName");
$("li.testID").click(function(){
$("li.testID").removeClass("selectedName");
$(this).addClass("selectedName");
$(".testimonial").hide();
$(this).next(".testimonial").fadeIn("slow");
});
});
</script>
Example of markup
<ul id="testName">
<li class="testID">Persons Name</li>
<blockquote class="testimonial">
<span class="bqStart">“</span>
Testimoinal here
<span class="bqEnd">”</span><br /><br />
<span class="testAuthor"><b>Name</b><a target="_blank" href="#">Website</a> Company</span>
</blockquote>
As a side note this is working fine in FF and Safari
Your help is greatly appreciated.
Thanks.
It's probably not working in IE because it's not valid markup: you can't have a blockquote as a direct child of a UL, so IE probably stores them in some weird place in the DOM tree which means .next doesn't find them. Can you move the blockquote elements into the li?
Is .testimonial the class you have given to your lists? <ul> or <ol>
It seems as if you are trying to get the next testimonial list to show, when infact you are actually getting the next <li> which has a class of .testimonial which I suspect is incorrect as you are using .testID as the class for your list items.
Please try this instead:
$(this).parent().next(".testimonial").fadeIn("slow");
