Everything I've searched for has shown about making a full div clickable, what I'm wondering is, is it possible to make a div in to a clickable link using just JavaScript and the div ID?
I have a layout of boxes and if a value in my database, I want PHP to echo some values in to JavaScript and say if this box is taken, give this div (boxID) the link that relates to it from the database. Only, there aren't going to be links on every div, as some won't exist in the database.
I suppose the alternative to this is wrapping each div in a <a> tag and an if exists statement?
In pure JS:
document.getElementById('your-div').addEventListener('click', function() {
location.href = 'http://your-url.com'
}, false);
By jQuery
$('#your-div').on('click', function() {
location.href = 'http://your-url.com'
});
you can easily make it so that when you click your div you go to another page, like this (using jQuery)
$('#myId').click(function () {
window.location = 'newurl.php';
});
In html5 you can just do:
<div>test</div>
This solution is for html <= 4. For html5, please read #Spencer solution.
Since the javascript is probably not what you want (waiting for extra comments), here's a example of how to do this in pure html/css. An anchor tag that fills completely a div, making that div clickable.
html:
<div>
<a href = "http://whatever.com/">
</a>
</div>
css:
div {
width: 200px;
height: 200px;
position: relative;
background-color: red;
}
a {
display: block;
width: 100%;
height: 100%;
position: absolute;
top: 0;
left: 0;
background-color: rgba(0, 255, 0, 0.5);
}
Demo in jsfiddle (background-color added for demonstration purposes):

I'm trying to get the div to the bottom of the page but it's not working the way I want it to work for some reason. I've set the position of the div to relative, and the bottom to 0, but the thing is that if there are no text in between the div, the div doesn't go to the bottom. I need to div to be at the bottom when there are text in between and when there aren't text in between. How do I do that? Thanks.
div {
border: 1px solid black;
position: relative;
bottom: 0px;
}
<?php
while($num < 100) {
echo "Stuff<br>";
$num++;
}
?>
<div> Div </div>
If jQuery is an option you can do this.
(function($){
if($('div').is(':empty')) {
$('div').removeClass("bottom");
}
else{
$('div').addClass("bottom");
}
})(jQuery);
Here is a link. I made a small change to the CSS to the width as well.
You will need to use position absolute as stated by Lund.

Hope this helps.
If you want to use bottom: 0px; position has to be absolute.
I have made a div clickable using jquery. Is there a way to also tell the browser to display the target of the clickable div like it does for anchors? (example in the bottom left of the image below)
In answer to those suggesting using an anchor tag - That's not the question I asked. I want to avoid using anchor tags as that requires changing a lot of html, rather than a small amount of jquery. And even if changing the html to use anchors is the correct thing to do - it will still be useful to know if this is possible.
Edit it seems this is not easilly possible, but an alternative suggested by Pete, using jquery to wrap the div in an anchor works fine (better than I thought it would)
Just use a normal link and hide it:
a {
opacity: 0;
font-size: 100px;
}
div {
width: 100px;
height: 100px;
border: 1px solid red;
}
<div>
hidden link
</div>
jQuery is destroying me this week. I'm using fadeIn via jQuery on my portfolio site (http://www.codeisdna.com) to open up a section once it's clicked. Here's the HTML code I'm using:
<div class="project first project_name">
<div class="title">
Project Title!
<div class="date">2012</div>
</div>
<a class="expand" title="Click to expand the project." href="#project_1">Project Title!</a>
</div>
Which opens up a tab:
<div id="project_1" class="project_full pname"></div>
Using this js:
$(document).ready(function(){
$(".project").click(function() {
$("a.expand").removeClass("hovered");
$(this).find("a.expand").addClass("hovered");
$(".project_full").hide();
var selected_tab = $(this).find("a").attr("href");
$(selected_tab).fadeIn();
return false;
});
});
EDIT: Here is the CSS code for .project_full (the expanded tab -- the CSS code for .project is irrelevant):
.project_full {
display: none;
margin-top: 20px;
width: 100%;
max-height: 450px;
padding: 20px 0px;
text-align: center;
background: url(../img/code.jpg) top center no-repeat fixed #293134;
box-shadow: inset 0 0 10px rgba(0,0,0,0.5);
color: #fff;
overflow: hidden;}
.project_full .wrapper {position: relative;}
I've tried assigning a fixed height to a parent div, e.PreventDefault() doesn't work (I'm using anchor based tabs, so nothing of that sort will work), and so on. The page jumps on the first click and with each successive click. I know it jumps due to the missing content once the div is unhidden and "rehidden."
I'm wondering if HTML5 data attributes would remedy this? But then again, why would it as the anchor would still exist, albeit it being blank (#).
Hopefully someone with a lot more JS experience can help me!
Either change your handler adding preventDefault
$(".project").click(function(e) {
e.preventDefault();
$("a.expand").removeClass("hovered");
$(this).find("a.expand").addClass("hovered");
$(".project_full").hide();
var selected_tab = $(this).find("a").attr("href");
$(selected_tab).fadeIn();
return false;
});
Or change your a tag href attribute to be something like 'javascript:'
Or replace a tag with say span and let your click handler remain unchanged.
Or add name attribute to a tag (<a name='project_1'></a>) in right place as it is scrolling to this tag or beginning of the page as there is no ancor with corresponding name

As you can see there is a RED arrow located below the menu and what it is that I'm trying to achieve is... when I hover over a menu button the arrow moves to the same button I'm hovering over without reloading the page.
Ideally I'd like the arrow to move back to a default button.. and also for the default button to change if clicked on a different menu button.
If you know any links to examples etc... I would really appreciate it!
Thank you for your time,

The first thing is that you have a wrong DOCTYPE.
<!DOCTYPE html PUBLIC "">
This causes you page to load in quirk mode. Change it to
<!DOCTYPE html>
for HTML5 or use the complete one including the FSI & FPI.
Second is you are using a <table> for navigation. Nothing seriously wrong with it but people tend to use ul
For the :hover, you can simply use
#MenuPosition table tbody tr td:hover
{
background-image: url("/images/Arrow.jpg");
}
You might have to play with paddings and margins or maybe use display: block or display: inline-block to position the arrow correctly.
Make the "buttons" anchors. Using css set create a rule for :hover to set a background image that contains the arrow.
There are plenty of CSS tutorials out there, Nettuts and Webdesigntuts have a lot of navigation articles. Or if you are comfortable with emulating others, find a site you like and pick apart the source until you figure out how they did it.
Keep in mind that javascript is not at all necessary to accomplish what you are doing. Unless you want some animations, and even then CSS can handle most of that work, pure CSS in my opinion is the better approach.
PURE CSS SOLUTION
Check this answer.
Is there any way to hover over one element and affect a different element?
So it might be:
#thething {
margin: 0;
}
.classone:hover + #thething {
margin-top: 10px;
margin-left: 10px;
}
If they're adjacent siblings in a parent div.
Just move the arrow bymargin-left with respect to left of the td DEMO
$("#Arrow").css({"margin-left":$(this).position().left+($(this).width()/2)-2});
Tp do this Add jQuery libirary to the head section of your page
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
Add this code in a external js file and add it to head section of your page
$(function(){
$("#MenuPosition").on("hover","td",function(){
$("#Arrow").css({"margin-left":$(this).position().left+($(this).width()/2)-2});
});
});
EDIT : For restoring the arrow orignal position use
$(function(){
currentPos = $("#Arrow").css("margin-left");
$("#MenuPosition").on("hover","td",function(){
$("#Arrow").css({"margin-left":$(this).position().left});
});
$("#MenuPosition").on("mouseout","td",function(){
$("#Arrow").css({"margin-left":currentPos});
});
});
NOTE : PLEASE SEE THE CALCULATION PART AND CORRECT IT.
PS: cant correct is because its my log out time from office ;) . but i thing you got the logic to do it
You can do something like this:
Using a span to add the bg arrow below the nav/menu lis in the HTML:
<ul class="nav">
<li>
Menu 1
<span class="arrow"> </span>
</li>
<li>
Menu 2
<span class="arrow"> </span>
</li>
</ul>
The CSS:
.nav {
font-size: anypx;
list-style: none outside none;
margin: 0;
padding: 0;
position: relative;
}
.nav li {
background: #whatev;
display: block;
float: left;
height: anypx;
line-height: anypx;
padding: 0;
text-align: center;
}
.nav li a {
color: #any;
display: block;
padding: any;
position: relative;
text-decoration: none;
width: auto;
}
.arrow {
background: url("images/arrow.png") no-repeat scroll 0 9px transparent;
display: none;
height: anypx;
text-indent: -9999px;
width: whatevs;
z-index: 9999;
}
And Finally the JS/Jquery that makes it work:
$(document).ready(function(){
Your_menu();
});
function Your_menu(){
$(".nav li").hover(function(){
$(this).find('.arrow').css({visibility: "visible",display: "none"}).show();
},function(){
$(this).find('.arrow').css({visibility: "hidden"});
});
}
Here is a site that is showing this :)

OKay first off this is really really similiar to the http://dribbble.com homepage.
In the simplest form possible. I have an image, and i'm trying to CSS it so that when i hover over the image, a DIV shows up with some text and a partially transparent background color.
I have no idea how to do this..
Here is a start. IE6 won't do this, unless you make the parent an anchor (a).
HTML
<div class="container">
<img src="something.jpg" alt="" />
<div>some text</div>
</div>
CSS
.container div {
display: none;
opacity: 0.7; /* look into cross browser transparency */
}
.container:hover div {
display: block;
}
#alex, I think he wants the text to appear over the image, not under it. Two ways to fix this:
Add position:absolute to the div containing the text.
Use a background-image instead of an img tag.
I'd go with 1, as it's better semantically and better for accessibility to use img tags for content-bearing images.
If what you want to obtain is an effect like that on Dribbble page, then you do not need to create a div over an img.
It's sufficient to have 2 versions of the image, one normal and one desaturated and with luminosity increased (or something like that, to give the impression of "transparency").
Now you create a div with the image as background and on mouseover you switch background and add the text.
On mouseout you revert the changes.
EDIT: Of course in practice you will dynamically assign the images name (e.g. with PHP), but that's another story. You may even automagically generate the "transparent" image by using GD libraries I guess.
A little example:
CSS:
.squareImg
{
display: block;
width: 100px;
height: 100px;
background-image: url("100x100.jpg");
}
.squareImgOver
{
display: block;
width: 100px;
height: 100px;
background-image: url("100x100transp.jpg");
}
HTML
<div id="mydiv" class="squareImg" onmouseover="writeText();"
onmouseout="eraseText()"></div>
JS
function writeText()
{
var d = document.getElementById("mydiv");
d.className = "squareImgOver";
d.innerHTML = "something here!";
}
function eraseText()
{
var d = document.getElementById("mydiv");
d.className = "squareImg";
d.innerHTML = "";
}
</script>
I suggest using jQuery as it's easy to say "mouseover" triggers another thing to show up.
