Add icons inside textbox area onfocus event, using bootstrap and javascript

Does anybody knows how can I add some bootstrap icons to my textarea. Icons should show on focus and hide on focus out. This textarea is similary, if not the same as Facebook Add new status textarea.
All I was able to do is to expand and shrink textarea onfocus/focusout events, using JavaScript.
This is the code I have:
HTML:
<div class="jumbotron" style="height:150px">
<div class="col-lg-12">
<textarea class="expand" rows="3" cols="20"></textarea>
</div>
</div>
JS:
<script type="text/javascript">
$('textarea.expand').focus(function () {
$(this).animate({ height: "4em" }, 500);
});
$('textarea.expand').focusout(function () {
$(this).animate({ height: "2em" }, 500);
});
</script>
CSS:
.expand
{
height: 2em;
width: 50%;
}
I've also try using .css in JS and trying to add icon, but I suppose I don't do this right way, cause nothing gets shown.
$('textarea.expand').focus(function () {
$(this).animate({ height: "4em" }, 500);
$(this).css('glyphicon glyphicon-camera');
});
Textarea should behave like this:
OnFocusOut:
OnFocus:
Can someone help me, and give me an idea on how to do this...Because I'm pretty bad in JS.

One Simple answer can be creating a sibling div element to the textarea which will contain all the icons, show the div of focusing the textarea and hide it on focusout of the textarea

This example is using the selector
.parent:hover .links{}
but could be edited to
.parent:focus .links{}
if desired. However, to show you this in action, i've designed a simple demo below:
.parent{
height:100px;
width:70%;
background:red;
position:relative;
}
.parent:hover .links{
display:block;
}
.links{
display:none;
position:absolute;
bottom:0;
}
<div class="parent">
<div class="child">
<div class="links">
facebook twitter etc
<img src="http://placekitten.com/g/20/20" alt="" />
</div>
</div>
</div>
An example using Sibling selectors
Here is a working example of using the sibling selector
input:focus + .items
which selects the class .items of which has a sibling of 'input' which has a focus (i.e. what you're looking for)
#parent{
height:100px;
width:80%;
background:red;
position:relative;
}
.items{
bottom:0;
padding:5px;
display:none;
}
input:focus + .items{
display:block;
}
<div id="parent">
<input type="text" placeholder="enter text"/>
<div class="items">
<img src="http://placekitten.com/g/20/20" alt=""/>
<img src="http://placekitten.com/g/20/20" alt=""/>
<img src="http://placekitten.com/g/20/20" alt=""/>
</div>

How to change img src link mouse hover?

HTML
<div module="product_listnormal">
<ul>
<li>
<input type="checkbox" class="{$product_compare_class} {$product_compare_display|display}">
<div id="prdImgWrapper">
<img src="{$image_medium}" alt="" class="prdImgImg"/>
</div>
.....
So i Add onmouseover in img tag
<img src="{$image_medium}" onmouseover="this.src={$image_medium} + 'aaa'" alt="" class="prdImgImg"/>
but it doesn't call {$image_medium}aaa link what's wrong?
ex) if $image_medium = 111.png
$image_medium + aaa = 111aaa.png

I use on mouse over and on mouse leave function like this
onmouseover='this.src = this.src.replace(".jpg","_2.jpg")' onmouseleave='this.src = this.src.replate("_2.jpg", ".jpg")'
this source can use every picture

You have two links image_medium and image_medium2.
Say image_medium="a.jpg" and image_medium_2="a_2.jpg";
Using pure JavaScript
1) You can add listener for the same using mouseenter and mouseleave events if you know values
var divToBeHovered=document.getElementById("prdImgWrapper");
//add listener
divToBeHovered.addEventListener("mouseenter",function(){
var imgEle=document.querySelector("#"+this.id+" img");
imgEle.src="a_2.jpg"; //image_medium_2
},false);
divToBeHovered.addEventListener("mouseleave",function(){
var imgEle=document.querySelector("#"+this.id+" img");
imgEle.src="a.jpg"; //image_medium
},false);
2)If you don't know values i.e src of image is dynamic then you can create one function and call it both on mouseenter and mouseleave event.
<a href="/product/detail.html{$param}" class="prdImg">
<img src="{$image_medium}"
onmouseenter="changeURLOfImage(this,'{$image_medium}aaa')"
onmouseleave="changeURLOfImage(this,'{$image_medium}')"
mouseralt="" class="prdImgImg"/></a>
function changeURLOfImage(imageElem,url){
imageElem.src="url"
}
3)Assign direct values to src
<img onmouseenter='this.src ={$image_medium}aaa' onmouseleave='this.src ={$image_medium}'/>

This can be done using pure CSS by using two images and changing the display on hover state.
a.prdImg > img {
display: inline-block;
}
a.prdImg > img + img {
display: none;
}
a.prdImg:hover > img {
display: none;
}
a.prdImg:hover > img + img {
display: inline-block;
}
<div module="product_listnormal">
<ul>
<li>
<input type="checkbox" class="{$product_compare_class} {$product_compare_display|display}">
<div id="prdImgWrapper">
<img src="http://media-cache-ak0.pinimg.com/736x/65/7e/a2/657ea254eb522135fbd59e0656a2e1dd.jpg" alt="" class="prdImgImg"/><img src="http://baconmockup.com/400/300" alt="" class="prdImgImg"/>
</div>
.....
By the way; wouldn't cause this.src={$image_medium} + 'aaa' the src to change from 111.png to 111.pngaaa?

While changing image src is not possible with css you can have 2 images(one hidden) and a container and on container mouse hover hide first image and show the second image.
something like this:
Html:
<div>
<span>This could be an image</span>
<span>This could be an image</span>
</div>
CSS:
div{
float:left;
width:200px;
height:200px;
}
div span{
width:100%;
height:100%;
display:none;
background-color:red;
}
div span:first-child{
display:block;
background-color:lime;
}
div:hover span:first-child{
display:none;
}
div:hover span:nth-child(2){
display:block;
}
have a look:
http://jsfiddle.net/mzvaan/fs6mc952/

html code like
<img src="sample1.png" id="newimg">
script like this
$(document).ready(function(e) {
$("#newimg").hover(function() {
$("#newimg").attr('src', 'sample2.png');
})
});

Muliple hidden fullscreen divs?

I'm working on my portfolio website, but can't solve the following problem.
The website is basically just pictures, if you click on one,
a semi-transparent fullscreen div opens with information (more pics and some text).
If you click again the div will close.
jQuery for hiding and showing:
<script>
$(function()
{
$('.masonryImage').click(function()
{
$('.hiddenDiv').show();
$("body").css("overflow", "hidden");
});
$('.hiddenDiv').click(function()
{
$('.hiddenDiv').hide();
$("body").css("overflow", "auto");
});
});
</script
HTML:
<div class="masonryImage">
<img src="images/pic1.jpg" alt="">
</div>
<div class="hiddenDiv">
<div class="text">
<p>Lorem ipsum...</p>
</div>
<div class="pics">
<img src="images/pic2.jpg" alt="">
</div>
</div>
So far it works with one picture, but when I'm adding another,
the new hidden text will overlay the first one, same with the pictures.
Is it because I'm using the same class ("masonryImage")?
Or isn't my Javascript removing the divs properly?
Many thanks.
Edit: CSS might be usefull:
.hiddenDiv {
position:fixed;
top:0;
left:0;
background:rgba(255,255,255,0.8);
z-index:900;
width:100%;
height:100%;
display:none;
overflow: scroll;
}
.masonryImage {
margin: 20px 20px 20px;
display: inline-block;
cursor: pointer;
}

here is how I modified your code :
DEMO
HTML
<div class="masonryImage">
<img src="..." alt="">
<div class="hiddenDiv">
<div class="text">
<p>Lorem ipsum...</p>
</div>
<div class="pics">
<img src="..." alt="">
</div>
</div>
</div>
I put the hiddenDiv inside the masonryImage so every masonryImage will have a custom hiddenDiv to show/hide.
JQUERY
$('.masonryImage').click(function()
{
if ($(this).find('.hiddenDiv').toggle().is(":visible")) {
//alert('hiddenDiv is visible !');
$("body").css("overflow", "hidden");
}
else {
//alert('hiddenDiv is hidden !');
$("body").css("overflow", "auto");
}
});
You can just use .toogle() to show/hide the div. $(this) refers to the clicked masonryImage and .find('.hiddenDiv') to its child (you can also use .children('.hiddenDiv') ).
Then you can test if the clicked div is hidden or visible with .is(":visible"), to apply your body custom css :)
Hope I helped you.

How to change size of image in a active jQuery UI Tab?

I'm using jQuery UI tabs, and have an image inside the anchor of each tab list item (li). What I want to happen is for the image size to be a certain size for each inactive tab, and a larger size for the single active tab. I can't figure out how to do it. I'm not great with javascript and can't figure out how to get the script's if statement (see below) to be correct...all I was thinking I needed to do was to make it so that when there's a selected tab, the image inside that tab gets the larger dimensions.
Here's the script that I have:
<script type="text/javascript">
$(function() {
$( "#tabs" ).tabs();
if( $('#tabs .ui-tabs-active').attr('active') ) {
$('.theLogo').css({'width' : '120px' , 'height' : '60px'});
}
else {
$('.theLogo').css({'width' : '90px' , 'height' : '45px'});
};
});
</script>
Here's the HTML for the tabs:
<div id="tabs">
<ul>
<li><img src="picture1.png" alt="Picture 1" name="photo" id="photo" class="theLogo" /></li>
<li><img src="picture2.png" alt="Picture 2" name="photo2" id="photo2" class="theLogo" /></li>
<li><img src="picture3.png" alt="Picture 3" name="photo3" id="photo3" class="theLogo" /></li>
</ul>
<div id="tabs-1">
<iframe class="resultFrame" src="http://www.fakesite123.net"></iframe>
</div>
<div id="tabs-2">
<iframe class="resultFrame" src="http://www.fakesite1234.net"></iframe>
</div>
<div id="tabs-3">
<iframe class="resultFrame" src="http://www.fakesite1235.net"></iframe>
</div>
</div>
Thanks for any help!

Is there some reason you must do it with JS?
ul#tabs li a img {width: 90px; height: 45px;}
ul#tabs li.ui-tabs-active a img {width: 120px; height: 60px;}

Figured it out by using CSS instead of javascript. I put the following CSS:
.ui-state-default img {
width:90px;
height:45px;
}
.ui-state-active img {
width:120px;
height:60px;
}
I hope this helps someone who runs into the same problem.
Anyone that finds a javascript solution for this is more than welcome to post it!

Change image source on mouseover of parent div element

I have an image and rollover image. Using jQuery or CSS, I want to show/hide the rollover image when the onmousemove/onmouseout event happen on the parent div (containing the image).
How can I do it?
Edit: HTML posted below by request. Not relevant to the question, but as an FYI HTML is built on a 30 column fluid grid.
Upon hover of the top div (row-fluid) the image (image.png) should change to a different source image (imagehover.png).
<div class="row-fluid" style="padding-top:1em">
<div class="span4">
//Random content
</div>
<div class="span8 offset1">
//Random content
</div>
<div class="span9 offset3">
<ul>
<li>//Random content</li>
<li>//Random content</li>
<li>//Random content</li>
</ul>
</div>
<img src='../../images/image.png>
<div>

You want to do something like this: full_path_to_css parent:hover child
full_path_to_css parent:hover child {
styles for your item
}
eg:
html (the div.img can be anything):
<div class="parent">
<div class="img">
</div>
</div>​​​​​​​​​​​​​​​​​​
css:
div.​parent​ {
width:200px;
height:200px;
background-color:red;
}
div.img {
width:100px;
height:100px;
background-color:blue;
}
div.parent:hover div.img {
background-color:green;
}​
if you want to test check here: http://jsfiddle.net/NicosKaralis/kd6wy/
just to remember, the div with img class can be any element, doesn't need to be div and you can change the css styles as you wish, the only thing you need to watch is the parent:hover child
EDIT
Just to clarify one thing: the item with :hover is the parent on witch you want to detect the hover action, and the child is the item on witch you want to change the css rules
EDIT AGAIN
<div id="parent" class="row-fluid" style="padding-top:1em">
<div class="span4">
//Random content
</div>
<div class="span8 offset1">
//Random content
</div>
<div class="span9 offset3">
<ul>
<li>//Random content</li>
<li>//Random content</li>
<li>//Random content</li>
</ul>
</div>
<img class="child" src='../../images/image.png>
<div>
on your code you will need:
div#parent.row-fluid img.child {
display:none;
}
div#parent.row-fluid:hover img.child {
display:block;
}
this will make your image only show up if the mouse is over your div

Should just be as easy as attaching a mouseover and mouseout event handlers to the parent div and then manipulating the containing img element.
var rolloverImage = ...
var origImage = ...
$("#parentDivId")
.mouseover(function() {
$("#parentDivId img").attr("src", rolloverImage)
})
.mouseout(function() {
$("#parentDivId img").attr("src", origImage)
})

Try:
$('div.row-fluid').hover(function() {
$(this).find('img').attr('src', 'http://dummyimage.com/100x100/000/fff');
}, function() {
$(this).find('img').attr('src', 'http://www.placekitten.com/100/100');
});​
jsFiddle example

Without having any html to test with, this is just something I thought up in my head. Not sure if it will work or not, but I don't see why it wouldn't.
$('div').mouseenter(function() {
var image = $('img', this);
$(image.attr('src', 'new-image-src.jpg');
}).mouseleave(function () {
var image = $('img', this);
$(image).attr('src', 'old-image-src.jpg');
});

You can use this code to "show/hide the rollover image"
#parentDiv > img {
display: none;
}
#parentDiv:hover > img {
display: block;
}
The > allows you to select img tags that are the direct descendents of #parentDiv (I gave the outer div that ID). Then we're just setting a different style for it on regular and hover states.

Answering my own question, as I used elements of others' comments and answers to create a hybrid: a sprite, totally CSS solution. I find this to be optimal.
Per #gilly3 "Image swaps are best done with a sprite, so that there is never any delay switching between the images. Put both versions of the image side by side in a single file. Set that image to be the background of a div, and adjust the background position to display one or the other image." For this example, I will use a 96px (height) by 27px (width) sprite, using my em values.
In HTML replace img line with:
<div class="sprite-image"></div>
CSS:
.sprite-image {
{
background-image: url(../../images/image.png);
height: 3.7em;
width: 27px;
}
.row-fluid:hover .sprite-image
{
background-position: 0px -3.7em;
}
