I have a table set up in the following way, with each cell containing a span and a textarea:
<table>
<tr><td class="title">Original File</td></tr>
<tr><td><span id='ogline' onscroll="og.scrollTop=scrollTop"></span><span><textarea onscroll="ogline.scrollTop=scrollTop" onkeyup="linenumber()" id='og' onfocusout="linenumber()"></textarea></span></td></tr>
</table>
Along with that I have the following CSS:
<style>
span {
width:93%;
height: 100%;
}
textarea {
width:92%;
height: 100%;
border-style:solid;
border-color:black;
border-width:2px;
font-size:13px;
}
table {
width:100%;
height:100%;
}
.title {
height:5%;
text-align:center;
background-color:#009;
color:white;
}
#ogline {
padding-top:4px;
overflow:auto;
font-size:12px;
line-height:14.99px;
width:6%;
}
</style>
What I am trying to do is have the scroll bar of the span and the scroll bar of the textarea synch up. I've somewhat accomplished this using the onscroll event listener with the following code:
onscroll="og.scrollTop=scrollTop"
onscroll="ogline.scrollTop = scrollTop
This has somewhat accomplished what I want it to, with the span being about a line off of where it should be. The greatest problem I am having though is when I paste a large amount of text into the textarea. This almost completely doesn't work, with both scrollbars being completely off until I hold one of the scrollbars down for a significant amount of time before the other scrollbar will try to play catch up with the other.
Any suggestions? Is there maybe a better approach to this issue that I should try? Any help would be appreciated.
This could work:
var scrolling=false;
function og_scroll(el)
{
if (scrolling && el!=scrolling) {
return;
}
scrolling = el;
var textareas = document.getElementsByTagName('textarea');
for (var i=0; i<textareas.length; i++) {
if (textareas[i].id.indexOf('og')==0) { // searching for id==og*
textareas[i].scrollTop=el.scrollTop;
}
}
scrolling = false;
}
function up(num)
{
var area = document.getElementById('og'+num);
if (area.scrollTop > 0) {
area.scrollTop -= 15;
}
}
function down(num)
{
var area = document.getElementById('og'+num);
if (area.scrollTop < area.scrollHeight) {
area.scrollTop += 15;
}
}
function fix_mouse_scroll() {
var textareas = document.getElementsByTagName('textarea');
for (var i=0; i<textareas.length; i++) {
if (textareas[i].id.indexOf('og')==0) {
if ("onmousewheel" in document) {
textareas[i].onmousewheel = fixscroll;
} else {
textareas[i].addEventListener('DOMMouseScroll', fixscroll, false);
}
}
}
}
function fixscroll(event){
var delta=event.detail? event.detail : event.wheelDelta; // positive or negative number
delta = delta>0 ? 15 : -15;
event.target.scrollTop += delta;
//console.log(delta, ' with ',event.target.scrollTop);
}
Html part:
<tr><td> <span onmousedown='up(1)'>[UP]</span> <span onmousedown='down(1)'>[DOWN]</span> <textarea id='og1' onscroll="og_scroll(this);"></textarea></td></tr>
<tr><td> <span onmousedown='up(2)'>[UP]</span> <span onmousedown='down(2)'>[DOWN]</span> <textarea id='og2' onscroll="og_scroll(this);"></textarea></td></tr>
<tr><td> <span onmousedown='up(3)'>[UP]</span> <span onmousedown='down(3)'>[DOWN]</span> <textarea id='og3' onscroll="og_scroll(this);"></textarea></td></tr>

I am trying to make all my divs the same height even if the browser is resized. I have 4 icon boxes. each box has an icon, a title, and a description. I want to make all of them same size. that means if the highest height of the icon container div is 100px all icon holder div will be 100px. the following code is working but if I resize the browser some time the height of the container divs is much bigger than the actual height. what I am doing wrong? (Note the resize will only happen screen size above 767px) thanks
function allSameHeight(sameSec, sameImg, sameTitle, sameDesc) {
jQuery(sameSec).each(function () {
let highestImg = 0;
let highestTitle = 0;
let highestTxt = 0;
jQuery(sameSec).find(sameImg).each(function () {
if (jQuery(this).height() > highestImg) {
highestImg = jQuery(this).height();
}
});
jQuery(sameSec).find(sameTitle).each(function () {
if (jQuery(this).height() > highestTitle) {
highestTitle = jQuery(this).height();
}
});
jQuery(sameSec).find(sameDesc).each(function () {
if (jQuery(this).height() > highestTxt) {
highestTxt = jQuery(this).height();
}
});
if (jQuery(window).width() > 768) {
jQuery(sameSec).find(sameImg).css("min-height", highestImg);
jQuery(sameSec).find(sameTitle).css("min-height", highestTitle);
jQuery(sameSec).find(sameDesc).css("min-height", highestTxt);
} else {
jQuery(sameSec).find(sameImg).css("min-height", "auto");
jQuery(sameSec).find(sameTitle).css("min-height", "auto");
jQuery(sameSec).find(sameDesc).css("min-height", "auto");
}
});
}
Give a class to all four items. I've used myItem for instance.
const setHeights = () => {
let highestHeight = 0;
//Loop through all elements and get the highest height
$('.myItem').each((index, element) => {
if($(element).outerHeight() > highestHeight) {
highestHeight = $(element).outerHeight();
}
});
//Set the height of all elements to highest
$('.myItem').height(highestHeight);
};
$(window).resize(() => {
//Run each time window is resized
setHeights();
});
.myItem {
width: 25%;
color: white;
float: right;
}
.one {
background: red;
}
.two {
background: blue;
}
.three {
background: purple;
}
.four {
background: orange;
}
h3 {
word-wrap: break-word;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div>
<button onclick="setHeights()">Make them equal</button>
</div>
<div class="myItem one">
<h3>

</div>
<div class="myItem two">

<div class="myItem three">

<div class="myItem four">

For this case there are multiple approaches, I'll mention the two most common (in my opinion):

I have a div in which I can write any text up to 20 characters. But the text is getting out of the div.
I am setting it by decreasing font-size property on character count but it is not applicable on all cases.
Is there any way to do it by applying any twitter bootstrap rule?
<div id="overlay_image_text"></div>
if(cs < 6)
{
if(this.engravingFontCaseSenstiveOptions(cText) == "Lower")
{
$('#overlay_image_text').css({'margin-top':'-170px'});
$('#overlay_image_text').css({'font-size':68+'px'});
}
else if(this.engravingFontCaseSenstiveOptions(cText) == "Upper"){
$('#overlay_image_text').css({'margin-top':'-154px'});
$('#overlay_image_text').css({'font-size':48+'px'});
}
else{
$('#overlay_image_text').css({'margin-top':'-170px'});
$('#overlay_image_text').css({'font-size':64+'px'});
}
}
else if(cs > 5 && cs <= 7)
{
if(this.engravingFontCaseSenstiveOptions(cText) == "Lower")
{
$('#overlay_image_text').css({'margin-top':'-152px'});
$('#overlay_image_text').css({'font-size':47+'px'});
}
else if(this.engravingFontCaseSenstiveOptions(cText) == "Upper")
{
$('#overlay_image_text').css({'margin-top':'-140px'});
$('#overlay_image_text').css({'font-size':35+'px'});
}
else
{
$('#overlay_image_text').css({'margin-top':'-152px'});
$('#overlay_image_text').css({'font-size':47+'px'});
}
}
CSS for parent element
element.style {
display: block;
font-family: Cherokee;
}
Would need to see the CSS code of the parent element containing it but try
#overlay_image_text {
width:100%;
font-size: auto;
}
Hope you get the idea. Also, apply padding/margin in % as needed.
Are you looking for this?
Basically, I take advantage of the scale() in CSS and make the text fit in its parents. Please comment if you need further explanation ;)
$(function(){
$("#text").on("input", function(){
var thisWidth = $(this).width();
var parentWidth = $(this).parent().width();
var scalingFactor = parentWidth/thisWidth;
if (thisWidth > parentWidth) {
$(this).css("transform", "scale("+scalingFactor+")");
} else {
$(this).css("transform", "scale(1)");
}
});
})
#box {
width:400px;
background:#D8557F;
border:10px solid #D8557F;
height:100px;
}
#text {
font-size:54px;
white-space: nowrap;
float:left;
transform-origin:left;
}

I want to make a lot of slides in a one-page scrolling site. A neat way to do this was with a code from Stano. My problem is that this code was only meant to occur once per page. In order to make it fit my needs I made it into this fiddle. I realized that this would accumulate very fast into some rather messy coding if I had 20+ of these:
$(document).ready(function() {
var divs = $('.divs>div');
var now = 0; // currently shown div
divs.hide().first().show(); // hide all divs except first
$(".next").click(function() {
divs.eq(now).hide();
now = (now + 1 < divs.length) ? now + 1 : 0;
divs.eq(now).show(); // show next
});
$(".prev").click(function() {
divs.eq(now).hide();
now = (now > 0) ? now - 1 : divs.length - 1;
divs.eq(now).show(); // show previous
});
});
Is there any way to create a common ID/class for the divs and clickers (previous, next) or a container that ensures that the slider functions by itself without interrupting other sliders?
For example creating a variable with the ID of the container
var test = $('.container').attr('id') )
Implementing the ID in the divs
var divs = $(test).attr( 'id',$(test).attr('id') );
Implementing the ID in the next (and prev), so that when they are being clicked they will only affect the divs with the same ID
$(".next",test).click(function () {...
Maybe have a wrapper with a specific ID where the 3 divs (divs, prev and next) are includes and tell the script that they need to be in the same wrapper in order to affect each other.
<div ID="wrap1">
<div class="prev"></div>
<div class="next"></div>
<div class="divs"></div>
</div>
I do not know how the script will change. Maybe including .child() or .parent()?
I am very new at java scripting and hope that my question is understood properly. Please let me know if there is anything that needs to be clarified.
Check my code, each slider has now a function at document ready, not mixing thing around, and a jquery higher version was used.
$(document).ready(function () {
function FirstSlider(){
var divs = $('.div1>div');
var now = 0; // currently shown div
console.log(divs);
divs.hide().first().show(); // hide all divs except first
$(".nex1").click(function () {
divs.eq(now).hide();
now = (now + 1 < divs.length) ? now + 1 : 0;
divs.eq(now).show(); // show next
});
$(".pre1").click(function () {
divs.eq(now).hide();
now = (now > 0) ? now - 1 : divs.length - 1;
divs.eq(now).show(); // show previous
});
}
function SecondSlider(){
var divs = $('.div2>div');
var now = 0; // currently shown div
divs.hide().first().show(); // hide all divs except first
$(".nex2").click(function () {
divs.eq(now).hide();
now = (now + 1 < divs.length) ? now + 1 : 0;
divs.eq(now).show(); // show next
});
$(".pre2").click(function () {
divs.eq(now).hide();
now = (now > 0) ? now - 1 : divs.length - 1;
divs.eq(now).show(); // show previous
});
}
FirstSlider();
SecondSlider();
});

I am new to javascript and I am trying to do a featured content slider something like the top banner in this website http://www.homeplus.co.kr
As you can see, the top big banner changes automatically & also will change when user hovers over one of the list at the right.
Right now I am able to do the hovering part, but I am still stuck at the automatic changing content part.
Here's a sample jsfiddle: http://jsfiddle.net/StormSdq/5tWPy/2/
<div class="pi">a</div>
<div class="pi">b</div>
<div class="pi">c</div>
<div class="pi">d</div>
<div class="c1">I DREAM</div>
<div class="c1">OF LLAMAS</div>
<div class="c1">JUMPING AROUND</div>
<div class="c1">EATING BUSHES</div>
css:
.pi {
font-size:12px;
color:#000;
font-weight:700;
width:30px;
height:25px;
margin-right:10px;
background:transparent;
border-bottom:solid 1px black;
}
.c1 {
border:1px solid blue;
background:lightskyblue;
width:200px;
height:200px;
float:right;
margin-right:430px;
margin-top:-100px;
color:red;
font-size:25px;
text-align:center;
display:none;
}
javascript:
div = document.getElementsByClassName('c1');
div[0].style.display = 'block'
B = document.getElementsByClassName('pi');
B[0].onmouseover = function () {
blip(0);
};
B[1].onmouseover = function () {
blip(1);
};
B[2].onmouseover = function () {
blip(2);
};
B[3].onmouseover = function () {
blip(3);
};
function blip(y) {
div = document.getElementsByClassName('c1');
for (x = 0; x < (div.length); x++) {
div[x].style.display = 'none';
}
div[y].style.display = 'block';
}
Any help will be greatly appreciated
Try this:
var cur = 0; // current index
setInterval(autoAnim, 2000); // auto change every 2s
function autoAnim(){
if(cur > 3) cur = 0;
blip(cur);
cur++;
}
Here is jsfiddle
You can use the function setTimeout to call something after XX miliseconds.
var number=0;
setTimeout(automatic,5000); // every 5 seconds
function automatic(){
blip(number);
number++;
if (number > 4)
number=0;
alert("Hello");
setTimeout(automatic,5000);
}
You will probably want to make the function sleep when mouse is hover and some others condtions
I have two pages with almost the same code. Both have this CSS code and the two divs:
<style type="text/css">
.visfarve { position:relative; float:left; padding:5px; border:1px solid #666; }
.farver { border:1px solid black; width:75px; height:10px; }
.valgtfarve { width:95px; height:15px; display:block; background-color:white; text-align:center; }
</style>
<div id="vis" style="display:block; font-size:11px;">
Vis farver
</div>
<div id="skjul" style="display:none; font-size:11px;">
Skjul farver
</div>
One page then has this construct:
<table style="width:730px;">
<tr>
<td width="510px">
<div id="visfarve" style="display:none; margin-top:11px;">&npsp;</div>
</td>
<td id="viser" style="border-radius:10px; width:220px; height:inherit"></td>
</tr>
</table>
The other page has this obstruction:
<div id="visfarve" style="display:none; margin-top:11px;"> </div>
<div id="viser" style="margin-top:50px; border-radius:10px; display:none;"> </div>
They share these two js functions:

When I use the div construct the floating divs lies niceley next to each other with 5 divs in each line and breaks when the container div edge is reached. However, inside the td the divs insists on each having the full width of the td - resulting in only one div per line.
How do I get divs inside a td to keep width and float left?
Let's start from a jsFiddle link : Here
I think it's a good practice when you post question.
Please explain where is the problem, in the jsfiddle page I don't see your bug.
I did only little modification, no relevant code changes.
I only defined the variable
var skriv = "";
