want to know Simply the javascript to overlay a div on centre of the page.
Just want to use plain java script to show and hide a div on the center of the page with "Please wait..." message and disable the background. Also this div shoud show on top of the other content of the page.
My div looks like this
<div id='mydiv' style="display:none;" ><img src="myimg.gif" /> Please Wait... </div>
On click of a button , I want to show the div content center aligned on the page.
I do not want to use jquery,extjs,,etc to achieve this.
I have seen a few examples on the web with lot of other features added to a modal popup, just looking for something simple and clean.The bare minimum JS required to do this.
The div you want to display needs to have an ID:
<div id="loaderdiv">
Then in your javascript, you display this div with the following code:
document.getElementById("loaderdiv").style.display = '';
Thats the bare minimum you'll need.
Centering the image can be done using CSS:
<div style="position:absolute;top:50%;left:50%;margin-top:-[imgheight/2]px;margin-left:-[imgwidth/2]px">
<div class="overlay_msg" id="overlay_msg" style="width:350px; height:100px; background-color:#ffffff; margin-left:300px; margin-top:20%; visibility:hidden; z-index:201; position:fixed; padding:15px; text-align:center;">
example.com<br />
</div><!--overlay_msg-->
<div class="my_overlay" id="my_overlay" style="background-color:#000000; opacity:.7; position:fixed; z-index:200; width:100%; height:100%; margin:0px; padding:0px; visibility:hidden;" onclick="hideMyOverlay()">
</div><!--my_overlay-->
<script type="text/javascript">
function showMyOverlay()
{
document.getElementById('my_overlay').style.visibility='visible';
document.getElementById('overlay_msg').style.visibility='visible';
}
function hideMyOverlay()
{
document.getElementById('my_overlay').style.visibility='hidden';
document.getElementById('overlay_msg').style.visibility='hidden';
}
</script>

Hi I a creating a button using three divs and all divs have background images. This is how it looks like.
Button Demo
The button is fine but how can i resize it ?? I am doing like
.btncontainer{
position:absolute;
top:120px;
left:120px; cursor:pointer;
display:inline-block;
width:120px;
height:20px;
}
But it is changing the button design. What can i do to resize it dynamically with the text?
i want to look like this if the size is changed for example this image has different sizes.
So when i changing the .btncontainer then it should change the width and height of the elements inside it but this is not happening
As you precised in an upper comment; In this special case, you have to use images for left and right divs. I suggest you to set a proper height to them, in the html code.
This is not the best practise, but will do the work regarding your needs.
Please see the following example.
Please note you will have to change the #backgrounddiv height and line-height to match.
See fiddle here
CSS
.btncontainer{
position:absolute;
top:180px;
left:10px; cursor:pointer;
display:inline-block;
}
#leftdiv{
float:left;
}
#backgrounddiv{
background:url("http://i.share.pho.to/0ffe9c14_o.png") top center repeat-x;
float:left;
height:40px;
padding:10px;
line-height:40px;
}
#rightdiv{
float:left;
}
HTML
<div class="btncontainer" id="button">
<a href="#">
<div id='leftdiv'>
<img src="http://i.share.pho.to/ff6cc4e3_o.png" height="70px" />
</div>
<div id='backgrounddiv'>CLick Me </div>
<div id='rightdiv'>
<img src="http://i.share.pho.to/245be416_o.png" />
</div>
</div>
I have a html page, having two div's.Left div contains all contents(INDEX of pages) with hyper-links.Now i want to display the content in the right div, that the user has clicked.In right div i have divided the page horizontally into 3 parts..10%,80%,10%.In that 80% horizontal div it shd display the content.I tried by using the target attribute in anchor tag, but it is not showing in that right div.How to solve this?
You can Try This:
css:
div {
width:90%;
height:800px;
position:relative;
background-color:blue;
}
a {
color:white;
font-size:24px;
}
html:
<div id="one">Top of Page</div>
<div id="two">Go to Top</div>
<div id="three">Go to Two</div>
You can try using Iframes. Can refer this site to get started: http://www.dtp-aus.com/frm_sets/frames.html
First of all i'm new at scripting and need your help. I'm trying to achieve the following:
I have four projects i want to show on my website. These projects are visable by images. When people hover over the image a div called "info" will show the additional information of the project they hover on.
So to be clear, data which will be triggered by hovering goes to the same div "info":
Hover over image 1 -> load information of project 1 to -> div "info"
Hover over image 2 -> load information of project 2 to -> div "info"
etc.
A friend told me to use ajax and xml, is that a good combination?
Thanks for the help
You are right that a good way to load content dynamically on a page is to use Javascript and XML. A great way to get into using JavaScript is to load a library to help you operate on the contents of an HTML page. I definitely recommend JQuery.
I would highly recommend not loading the information from separate files, unless the content is a whole bunch of very large images.
Take look at this video: JQuery for Designers they do some really great videos that helped me understand JQuery when I was first starting. The page that I just linked to has some great techniques for switching content into the same place, and will give you some important UX (user experience) tips as well.
Ajax is the best choice to get the data....
But the variations comes at what type of Data...
if you need values from database JSON would be my choice
or
never mind any data can be smoothly framed
if you dont have too much hand on scripting
Just use Jquery Plugins to retrieve data using simple calls
Fancybox plugin CLICK HERE...
and the GUIDE to how to use

Thank you all for the response.
I solved the problem temporarily by using the technique given by Mark, using html and css. But, i think using javascript could make things easier and more organised. My knowledge about scripting is not good enough. I posted my html for others underneath.
I still have the question how to use the id of a image as a parameter for retrieving a specific part of information. For example: i have an image with id=img1 and a xml file containing with sub parameters. So when i hover over the image js gets the id of that image and then loads the specific part of the xml onto the "info"div and not the whole xml. (to answer the question of adam, the data type is just text)

<body>
<div class="maincontent">
<div class="leftcol">
<p>
Hover over the blue divs in the middle
</p>
<p>
This trick uses the > to find children of an element.
The children are only displayed when hovering over the parent element.
Look at the CSS how that is done. for instance for the left div it is
div.square:hover > div.left_content
</p>
<p> something inside the left column</p>
</div>
<div class="rightcol">
<p>something inside the right column</p>
</div>
<div class="middlecontent">
<div class="square">
<!--
this div has two children
a div with class="left_content" and
a div with class="right_content"
-->
<div class="left_content">
<p> first div </p>
<p> something as left content </p>
</div>
<div class="right_content">
<p> first div </p>
<p> something as right content </p>
</div>
</div>
<div class="square">
<div class="left_content">
<p> second div </p>
<p> something as left content </p>
</div>
<div class="right_content">
<p> second div </p>
<p> something as right content </p>
</div>
</div>
<div class="square">
<div class="left_content">
<p> third div </p>

basically, what i am trying to achieve is the following layout;
http://farm9.staticflickr.com/8256/8746793625_d3fed90c54_b.jpg
I have tried using tables, but could not get the images to 100% of the page height.
I have tried crating an unordered list with display:inline and the images resized correctly, but I could not 'centre' on the "main" or second item in my list.
I am limited by the fact that I can't specify the dimension's of the images.
I would like to stick to CSS of possible, unless maybe there is a way of testing the window size with Jquery and feeding that in somehow? (im pretty new to this)
I'm all out of ideas, can anyone help?!?!
Cheers!
This is as close as I got;
<body>
<div class="wrapper" style="position:absolute; width:100%; height:100%; margin:0; padding:0; top:0; left:0;">
<table style="position:absolute; width:100%; height:100%; margin:0; padding:0; top:0; left:0; text-align:center; white-space: nowrap; overflow:hidden;">
<td style="width:20%" ><img style="position:relative;width:auto;max-height:100%" src="http://shellsuitzombie.co.uk/wp-content/uploads/2013/04/Brad-Rose-I-never-finish-anything.jpg"></td>
<td style="width:60%" ><img style="position:relative;width:auto;max-height:100%" src="http://shellsuitzombie.co.uk/wp-content/uploads/2013/04/Brad-Rose-I-never-finish-anything.jpg"></td>
<td style="width:20%" ><img style="position:relative;width:auto;max-height:100%" src="http://shellsuitzombie.co.uk/wp-content/uploads/2013/04/Brad-Rose-I-never-finish-anything.jpg"></td>
</tr></table></div></body>
The problem should be in your arrangement of tables
will you please check out the table and where you sending your upload file . weather is calling the jQuery or not your jquery function is called or not and put the image width and height to 100% and if you give me your site link I will do for you.
I am new to CSS and Javascript. I want to create a specific area (I use the div tag) in the page where once a link is clicked within, the area will expand and an additional content would be displayed. I managed to create a code which does the job only partially: the new content is displayed after the click but this content is not displayed within the area border. In few words the area is not expanded, only a new content is displayed...any suggestion?
I really like this jQuery accordion method:
Live Demo: http://jsfiddle.net/kbZDv/1/
It's easy to use, style and looks good.
All you need to do is include the latest version of jQuery:
<script type="text/javascript" src="http://code.jquery.com/jquery-latest.js">
Here is the HTML markup:
<p class="trigger">Click here to expand and reveal more information</p>
<div class="toggle_container">
<div class="block">
<p>Content goes here.</p>
</div>
</div>
The basic (yet to be styled) CSS:
p.trigger{
margin-bottom:7px;
margin-top:-5px;
}
.toggle_container{
margin-bottom:10px;
}
.toggle_container p{
margin:0px;
}
.toggle_container{
background:#f0f0f0;
clear: both;
font-size:100%;
}
And the all important jQuery to make it work:
$(".toggle_container").hide();
$("p.trigger").click(function(){
$(this).toggleClass("active").next().slideToggle("normal");
});
You could use a jquery plugin like div expand?
http://plugins.jquery.com/plugin-tags/div-expand
or perhaps a jquery exander plugin
