Resize textarea after deleting text - javascript

If you write text, a textarea increases in size, but when you delete this text then nothing happens. Is it possible to dynamically decrease the height of a textarea if you are deleting text?
$('textarea').on('input', function() {
var scrollHeight = parseInt($(this).prop('scrollHeight'));
$(this).height(scrollHeight);
});
.OuterDiv
{
width:200px;
height:300px;
border:1px solid #000;
position:relative;
bottom:0;
}
.text
{
resize:none;
width:198px;
height:45px;
max-height:145px;
background-color:rgba(90,90,180,1);
font-size:16px;
font-family:Arial;
overflow-y:auto;
padding:0;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="OuterDiv">
<textarea class="text" placeholder="Write some text..."></textarea>
</div>

Set the height style instead of the property, and use an initial height so as to always start at 45px.
$('textarea').on('input', function() {
$(this).css('height', "45px");
$(this).css('height', this.scrollHeight+"px");
});
.OuterDiv
{
width:200px;
height:300px;
border:1px solid #000;
position:relative;
bottom:0;
}
.text
{
resize:none;
width:198px;
height:45px;
max-height:145px;
background-color:rgba(90,90,180,1);
font-size:16px;
font-family:Arial;
overflow-y:auto;
padding:0;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="OuterDiv">
<textarea class="text" placeholder="Write some text..."></textarea>
</div>

You could use a div with contentEditable instead it will auto-resize depending on the contentno need for any script :
.OuterDiv
{
width:200px;
height:300px;
border:1px solid #000;
position:relative;
bottom:0;
}
.text
{
resize:none;
width:198px;
min-height:45px;
height:auto;
max-height:145px;
background-color:rgba(90,90,180,1);
font-size:16px;
font-family:Arial;
overflow-y:auto;
padding:0;
}
[contenteditable=true]:empty:before{
content: attr(placeholder);
display: block; /* For Firefox */
color: grey;
}
<div class="OuterDiv">
<div class="text" contentEditable="true" placeholder="Write some text..."></div>
</div>

Background shows progress of input characters

I have an input field and I want that the background of the input field fill every time when some type something in. So the background shows the progress of the input field.
<input class="controlinput" id="title" maxlength="156" data-class=".title" type="text">
156 characters are the 100%;
$("#title").on('keyup', function(){
var maxlength = $(this).attr("maxlength");
var percentage = Math.floor($(this).val().length / maxlength * 100) + '%';
$("#percentage").text(percentage);
$("#bg").css({width: percentage});
})
.container {
position:relative;
display:inline-block;
}
#bg {
position: absolute;
left:0px;
background-color:lightblue;
width:0%;
height:16px;
top:1px;
z-index:0;
}
#title {
padding-right:30px;
position:relative;
z-index:1;
background:transparent;
}
#percentage {
font-size:10px;
color:#777;
position:absolute;
right: 5px;
top:3px;
z-index:2;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Jquery textcomplete div

Hi everyone i have one question about jquery textcomplete.
I think this is easy but i don't know how can i do that.
I created this DEMO without jquery
So what is my question. I want when i write in textarea open parenthesis ( then .textBox div automatically open.
How can i do that anyone can tell me?
<div class="container">
<div class="textarea_wrap">
<textarea id="textarea" class="text"></textarea>
<div class="tagBox"></div>
</div>
</div>
CSS
.container{
width:300px;
height:300px;
margin:0px auto;
margin-top:30px;
}
.textarea_wrap{
width:100%;
box-sizing:border-box;
position:relative;
}
.text{
width:100%;
height:100px;
box-sizing:border-box;
outline:none;
border:1px solid #999999;
}
.tagBox{
width:300px;
height:100px;
background-color:red;
position:absolute;
top:100px;
display:none;
}
You can do something like this.
UPDATED
$(document).ready(function(){$('#textarea').keyup(function(){
if(($('#textarea').val() =="(" || $('#textarea').val().indexOf("(")>0) && $('#textarea').val().lastIndexOf("(") == $('#textarea').val().length-1 ){
$('.tagBox').show();
}else{
$('.tagBox').hide();
}
});
});
.container{
width:300px;
height:300px;
margin:0px auto;
margin-top:30px;
}
.textarea_wrap{
width:100%;
box-sizing:border-box;
position:relative;
}
.text{
width:100%;
height:100px;
box-sizing:border-box;
outline:none;
border:1px solid #999999;
}
.tagBox{
width:300px;
height:100px;
background-color:red;
position:absolute;
top:100px;
display:none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
<div class="textarea_wrap">
<textarea id="textarea" class="text"></textarea>
<div class="tagBox"></div>
</div>
</div>
See the Working Fiddle Using regex instead of several conditions :
JS :
$(function(){
$('#textarea').keyup(function(){
if($(this).val().match(/([(]$)/g)){
$('.tagBox').show();
}else{
$('.tagBox').hide();
}
});
})

CSS with right border - Nested

I am attempting to nest some divs. Each div is a unit which contains a right div and a left div. The left div can contain more units or single non-child units. Basic tree structure. However, I can't seem to get the css to work for what I'm going for.
I've created a js fiddle for it, listed below. The code is also below. I've also included a picture of what I'm going for. Any help is appreciated. I am open to jquery/javascript solutions.

Image for Reference
I have used nested classes and nth-child or nth-of-type basing on your html structure.
Bear in mind I have used padding-bottom: 22px to take into account of your 2px border.
You can try:
#main{
width:600px;
height:600px;
position:relative;
}
.inmain{
width:100%;
position:relative;
height:100%;
}
.inmain:nth-of-type(2){
border:2px solid black;
position:relative;
height:100%;
width:96%;
}
.inmain:nth-child(1) .inleft{
background:white;
position:relative;
width:100%;
margin-right:20px;
height:100%;
padding-bottom:22px;
}
.inmain:nth-child(2) .inleft{
background:blue;
position:relative;
width:100%;
margin-right:20px;
height:100%;
padding-bottom:0;
}
.inmain .inleft .inmain .inright{
background-color:#00FF00;
position:absolute;
width:20px;
right:0px;
top:0px;
height:100%;
padding-bottom:0;
}
.inmain .inright{
background-color:#00FF00;
position:absolute;
width:20px;
right:0px;
top:0px;
height:100%;
padding-bottom:22px;
}
Check this DEMO: http://jsfiddle.net/atsFA/12/
Using the below JQuery method with the css worked. The 22px less on the width is to account for a scroll bar, if one is used.
function setConstructSizes(element) {
//Set split group heights
element.find(".inthing").each(function () {
var hR = $(this).parent().parent().children(".inright").first().height();
if (hR > $(this).height()) {
$(this).height(hR);
}
});
//Set width of all inner lefts
element.find(".inleft").each(function () {
var p = $(this).parent();
var w = p.width();
$(this).width(w - 22);
});
//Set height of all inner rights
element.find(".inright").each(function () {
$(this).height($(this).parent().height());
});
}
.inmain
{
position:relative;
width:100%;
border-top:1px solid black;
border-bottom:1px solid black;
text-align:left;
}
.inleft
{
position:relative;
}
.inright
{
text-align:center;
border-left:1px solid black;
border-right:1px solid black;
width:20px;
position:absolute;
right:0px;
top:0px;

Image resizing issue in Slides

The problem is, in one of my pages I have a slide, where my images are 1920x1080 while the slide is just set to 1350 as width. My images are not getting centered, you just see about 1/3 of the picture's top left-middle-ish. The slide also doesn't reach out to the ends (<---->) of the screen, there's this tiny space there. Any solutions?

The solution is very simple actually.
You need to set a width to your images to 100% in your CSS.
.bjqs img {
width:100%;
}
Hope that helps, good luck

How to hide the div on any click outside

I am starting up on jquery and was tryin to create a simple div hide and show effect. The effects seem to work fine but i need that when user clicks on any other part of the document(i. except the hide/show box), the box should hide back. This is the jsfiddle :
http://jsfiddle.net/39DzJ/. I have not styled it properly. I wanted the effects to work first.
Can anyone help me out ?
Here's the HTML code :
<style>
#mail_floater
{
background:#fce8bd;
height:88px;
width:342px;
border:1px solid #b7ad02;
border-radius:5px;
position:absolute;
left:200px;
top:50px;
border-top:none;
z-index:100;
padding:0;
}
#subscribe_user
{
width:248px;
height:16px;
border:1px solid #b7ad02;
}
#cust_care_floater
{
background:#fce8bd;
height:12px;
width:108px;
border:1px solid #b7ad02;
border-radius:2px;
border-bottom-left-radius:2px;
position:absolute;

top:30px;
border-top:none;
z-index:100;
clear:both;
font-family:Tahoma, Geneva, sans-serif;
font-size:10px;

#closer
{
float:right;
margin-right:5px;
margin-top:2px;
width:19px;
height:19px;
background:url(../images/close.png) no-repeat;
}
</style>
</head>
<body>
Subscribe
Customer care
<div id="mail_floater">
<h5>Email</h5>
<div id="closer"></div>
<div id="email_input"><form><label>Enter E-mail : </label><span><input type="text" id="subscribe_user" /></span>
<input type="submit" id="subscribe_me" value="Done" /></form></div>
</div>
<div id="cust_care_floater">
<span style="padding:0px 10px 0 10px;">033-993-99920</span>
</div>
</body>​
The javascript code :
$(document).ready (
function()
{
var disp_box=$('#mail_floater');
var sub_link=$('#subscribe');
var disp_box_2=$('#cust_care_floater');
var sub_link_2=$('#customer_care');
disp_box.hide();
disp_box_2.hide();
sub_link.click
(
function()
{
disp_box.show();
});
disp_box.find('#closer').click
(
function()
{
disp_box.hide();
});
sub_link_2.click
(
function()
{
disp_box_2.show();
});
});​
$(document).on('click', ':not(.hideDiv)', function(e){
if($(e.target).is(':not(.hideDiv)')) { //extra check for good measure
$('.hideDiv').hide();
}
});​
