On clicking a button my program will create a dynamic div with a class name dynamictextbox . There is a label with the class name mytxt and textbox with class name mytext inside this div which is also dynamically created.
When i create a new dynamic div it is overlapping with previously created div.
Below is the CSS i've used
.dynamictextbox{
width:50%;
position:relative;
padding:10;
}
.dynamictextbox .mytxt{
position:absolute;
left:0px;
right:50%;
}
.dynamictextbox .mytext{
position:absolute;
left:51%;
right:100%;
}
Below is the HTML code
<div id="Enter your name" class="dynamictextbox">
<label class="mytxt">Enter your name</label>
<input type="text" name="Enter your name_name" id="Enter your name_id" class="mytext">
</div>
<br />
<div id="bigData" class="dynamictextbox">
<label class="mytxt">Now this is a long text which will overlap the next div.Need solution for this. Please give me a solution for this</label>
<input type="text" name="bigData_name" id="bigDate_id" class="mytext">
</div>
<br />
<div id="div_temp" class="dynamictextbox">
<label id="txtlb" class="mytxt">Dynamic Label</label>
<input type="text" name="tb" id="tb" class="mytext">
</div>
<br />
What you need here, is to expand the element according to the content height. Unfortunately you cannot do this using CSS. So we'll have to move along with javascript.
Here goes the script
<script>
var max = 0;
function setHeight() {
var elements = document.getElementsByClassName('mytxt');
var height = 0;
for (var i = 0; i < elements.length; i++) {
height = elements[i].scrollHeight;
if (height > max) {
max = height;
}
}
elements = document.getElementsByClassName('dynamictextbox');
for (var i = 0; i < elements.length; i++) {
elements[i].style = "min-height: " + max + "px";
}
}
</script>
At the end of all the divs call the funtion setHeight().
<script>setHeight()</script>
So the output will look like this
P.S. I've added borders to the class dynamictextbox for testing purposes.
This may be helpful - JSFIDDLE
Just remove the .mytxt class from your CSS and increase the left attribute of .mytext class
.dynamictextbox .mytext{
position:absolute;
left:60%;
right:100%;
}
Update the code below. Is this what you where going after?
$("#add").on("click", function(){
// just a helper function for some random content
function dynamicText(){
var min = 1;
var max = 50;
var random = Math.floor(Math.random() * max) + min;
var text = "";
for(var i = 0; i < random; i++){
text += "text ";
}
return text;
}
// add to the container
var addMe = "\
<div class='dynamictextbox'>\
<label class='mytxt'>"+dynamicText()+"</label>\
<textarea class='mytext'>"+dynamicText()+"</textarea>\
</div>\
";
var container = $("#container");
container.append(addMe);
});
.dynamictextbox{
width:50%;
padding:10;
margin-top: 10px;
background: #CCC;
overflow: auto;
}
.dynamictextbox .mytxt{
position: relative;
float: left;
width: calc(50% - 10px);
}
.dynamictextbox .mytext{
float: right;
width: calc(50% - 10px);
height: auto;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>

I am currently creating a meme generator app where the user can submit an image, as well as top and bottom text. I want to make it so that after form submission, the text is added onto the image and styled using CSS. I have already tried adding a class to the elements and adding css to it but that does not work. Here is my code:
JS
let form = document.querySelector('#meme-form');
let img = document.querySelector('#img');
let topTxt = document.querySelector('#top-txt');
let bottomTxt = document.querySelector('#bottom-txt');
form.addEventListener('submit', function(e) {
e.preventDefault();
let memePic = document.createElement('img');
//create the divs for the memes
let newDiv = document.createElement('div');
form.appendChild(newDiv);
topTxt.classList.add('top')
bottomTxt.classList.add('bottom')
memePic.src = img.value;
newDiv.append(memePic, topTxt.value, bottomTxt.value);
//set the textbox inputs equal to nothing
img.value = '';
topTxt.value = '';
bottomTxt.value= '';
})
CSS
div {
width: 30%;
height: 300px;
margin: 10px;
display: inline-block;
}
img {
width: 100%;
height: 100%;
margin: 10px;
display: inline-block;
}
.top{
color: blue;
}
#bottom-txt {
color: red;
}
HTML
<body>
<form action="" id="meme-form">
<label for="image">img url here</label>
<input id="img" type="url"><br>
<label for="top-text">top text here</label>
<input id="top-txt" type="text"><br>
<label for="bottom-text">bottom text here</label>
<input id="bottom-txt" type="text"><br>
<input type="submit"><br>
</form>
<script src="meme.js"></script>
</body>
</html>
You just need to fix up some of logic how the elements are being appended after form is submitted.
For that you need to div after your form which will hold you results and then order your element to be displayed. I have also added a line hr to have separator between each results displayed.
You can style your element the way you would like them to be - i have added some basic CSS to show some styling and an actual img url for demo purpose only.
Live Working Demo:
let form = document.querySelector('#meme-form');
let img = document.querySelector('#img');
let topTxt = document.querySelector('#top-txt');
let bottomTxt = document.querySelector('#bottom-txt');
let results = document.querySelector('.meme-results');
form.addEventListener('submit', function(e) {
e.preventDefault();
let memePic = document.createElement('img');
var hrLine = document.createElement('hr');
//create the divs for the memes
let newDiv = document.createElement('div');
let topText = document.createElement('span');
let bttomText = document.createElement('span');
//Top text
topText.classList.add('top')
topText.textContent = topTxt.value
//Img
memePic.src = img.value;
results.appendChild(topText);
results.append(memePic);
//bottom text
bttomText.classList.add('bottom')
bttomText.textContent = bottomTxt.value
results.append(bttomText);
results.append(hrLine);
//set the textbox inputs equal to nothing
//img.value = '';
topTxt.value = '';
bottomTxt.value = '';
})
.meme-results {
width: 30%;
height: 300px;
margin: 10px;
display: block;

img {
width: 100%;

<div class="range-wrap">
<input id="range" type="range" name="range" min="3" max="20" value="10" step="1">
<label id="rangevalue">10</label>
</div>
I to need to create range slider, where the values below 7 are labelled modest, 7 to 15 as moderate and anything above labelled as extensive. How I do add these labels to my range slide?
The idea will to be just simply get the value of existing slider and based on the value, do an if statement.
And to get the value when someone moves the slider, you can use oninput.
Try this:
First Answer Without The Partition
var slider = document.getElementById("range");
var display = document.getElementById("display");
var getVal = slider.value;
numVal.innerHTML = getVal; // If you don't want the number to be displayed, delete this. This is to show at which number the label will change
if(getVal<7) {
display.innerHTML = "Modest";
}
if(getVal>=7 && getVal<=15) {
display.innerHTML = "Moderate";
}
if(getVal>15){
display.innerHTML = "Extensive";
}
slider.oninput = function() {
numVal.innerHTML = this.value;// If you don't want the number to be displayed, delete this. This is to show at which number the label will change
var getVal = this.value;
if(getVal<7) {
display.innerHTML = "Modest";
}
if(getVal>=7 && getVal<=15) {
display.innerHTML = "Moderate";
}
if(getVal>15){
display.innerHTML = "Extensive";
}
}
<div class="range-wrap">
<input id="range" type="range" name="range" min="3" max="20" value="10" step="1">
<label id="display"></label>
<p id="numVal"></p> <!-- If you don't want the number to be displayed, delete this. This is to show at which number the label will change -->
</div>
ps: I've added comments in the code to hide the number if you don't want it. The numbers are there so you can see the change is happening at the right number. Delete the commented code accordingly to hide number values from displaying.
Updated Answer: (with partition)
You can use child elements to create a bar and push it on top of the slider using absolute and relative position. Its just a simple CSS trick.
The idea is to set a width for your range. Then, create 2 divs that looks like bars using border-right and then absolutely position it to your parent (which would be the range input)
Try this:
var slider = document.getElementById("range");
var display = document.getElementById("display");
var getVal = slider.value;
numVal.innerHTML = getVal; // If you don't want the number to be displayed, delete this. This is to show at which number the label will change
if(getVal<7) {
display.innerHTML = "Modest";
}
if(getVal>=7 && getVal<=15) {
display.innerHTML = "Moderate";
}
if(getVal>15){
display.innerHTML = "Extensive";
}
slider.oninput = function() {
numVal.innerHTML = this.value;// If you don't want the number to be displayed, delete this. This is to show at which number the label will change
var getVal = this.value;
if(getVal<7) {
display.innerHTML = "Modest";
}
if(getVal>=7 && getVal<=15) {
display.innerHTML = "Moderate";
}
if(getVal>15){
display.innerHTML = "Extensive";
}
}
#range-wrap {
position: relative;
}
input[type=range] {
width: 200px;
}
#range-bars {
width: 1px;
height: 10px;
border-right: 2px solid black;
position: absolute;
top: 13px;
left: 47px;
}
#range-bars-two {
width: 1px;
height: 10px;
border-right: 2px solid black;
position: absolute;
top: 13px;
left: 157px;
}
<div class="range-wrap">
<input id="range" type="range" name="range" min="3" max="20" value="10" step="1">
<label id="display"></label>
<p id="numVal"></p> <!-- If you don't want the number to be displayed, delete this. This is to show at which number the label will change -->
<div id="range-bars"></div>
<div id="range-bars-two"></div>
</div>

A div is not an image container. Replace with img in the createElement fixes this.
Another big problem is the margins you use.
I've made a few adjustments
replaced margin-left with float: right for the select
put margin auto for left and right on the box.
imageObj = new Image(128, 128);
// set image list
images = new Array();
images[0] = "final_images/wcoat.jpg";
images[1] = "final_images/wcoat.jpg";

You need to use an image tag instead of a div. You could also load images with CSS but thats probably not what you want.
starting on this line:
var holder = document.getElementById("holder");
var image = new Image(128, 128);
if (document.getElementById('selectBox').value == "womens") {
image.src = images[0];
holder.appendChild(image);
holder.appendChild(document.createTextNode(" Women's coat"));
} else if (document.getElementById('selectBox').value == "mens") {
image.src = images[1];
holder.appendChild(image);
holder.appendChild(document.createTextNode(" Men's coat"));
}
Let me elaborate.
In the JavaScript code you are creating a div element here
newdiv = document.createElement('div'); //create a div
newdiv.id = 'holder';
mainDiv.appendChild(newdiv);
and then you are searching for element with Id holder and setting new image url.
var holder = document.getElementById("holder");
// holder is <div></div> element
if (document.getElementById('selectBox').value == "womens") {
holder.src = images[0] + " Women's coat";
} else if (document.getElementById('selectBox').value == "mens") {
holder.src = images[1] + " Men's coat";
}
holder is a div tag now. it has no src attribute
But div element do not have attribute with name src. so the above code will just add one more attribute to your div tag. but browser will not interpret it.
So if you want load image by setting src attribute, then you probably have to create holder as img tag which has attribute src. like this.
newdiv = document.createElement('img'); //create a img
newdiv.id = 'holder';
mainDiv.appendChild(newdiv);
holder is a img tag. now it has src attribute
now it will work with no problem.
Here I want to randomly change the CSS of each character of text.
Like if I input Stack I will get S in red, t in blue, a in green... etc on the bottom of the input field.
var myModel = {
name: "Mayur",
};
var myViewModel = new Vue({
el: '#my_view',
data: myModel
});
span{
color:green;
font-weight:600;
font-size:20px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/1.0.26/vue.min.js"></script>
<div id="my_view">
<label for="name">Enter name:</label>
<input type="text" v-model="name" id="name" name="name" />
<p>Welcome, <span>{{ name | uppercase }}</span></p>
</div>
I haven't worked with Vue and I'm not familiar with its internal events and processes, but here's a tiny prototype i made in plain JavaScript:
document.querySelector('button').onclick = function (){
let span = document.querySelector('span.letters'),
text = span.textContent;
span.innerHTML = '';
Array.from(text).map(function(l){
let color = document.createElement('span');
color.innerHTML = l;
color.style.color = 'rgb(' +
randInterval(0, 255) + ',' +
randInterval(0, 255) + ',' +
randInterval(0, 255) + ')';
span.appendChild(color);
});
}
function randInterval(min,max)
{
return Math.floor(Math.random()*(max-min+1)+min);
}
<div><span class="letters">STACK</span></div>
<button>Random colors</button>
I've purposefully placed the function that randomizes each value of rgb() in a function, so you can alter it easily (now the colors are trully random). If you want to make the darker, you need to lower the max values. If you want the colors lighter, you need to increase the mins.
Html:
<div>Type something here, then click on the white space beneave.</div>
<input type="hidden" id="hidden">
Javascript:
$("div").prop("contentEditable", true).blur(function(){
var chars = $(this).text().split("");
$("#hidden").val($(this).text());
this.innerHTML = "";
$.each(chars, function(){
$("<span>").text(this).css({
color: "#"+(Math.random()*16777215|0).toString(16)
}).appendTo("div");
});
});
Css:
div{
border: 1px solid black;
width: 400px;
height: 20px;
padding: 2px 3px;
overflow: hidden;
}
You can visit http://jsfiddle.net/DerekL/Y8ySy/ for the implementation!
Both html and css codes are given in the link.
It gives the colour to the characters randomly but it can be manipulated easily or if you want them to run randomly, you can use it directly.

Hi, I am very new to javascript. What I am trying to do, is change the x-position of a div when another div (NavigationForward or NavigationBackward) is clicked. However it does not appear to do anything at all. Basically if the div with name forward is clicked, I want to translate the VideoWrapper -100% from it's current position and +100% when "back". The css div itself VideoWrapper has a width of 300%. Inside this div as you can see is a SlideShowItem which is what will change. Perhaps I am adding and subtracting 100% the wrong way?
EDIT:
Thanks everyone for helping me out with this...I had just one more query, I am trying to hide the arrows based on whether the wrapper is at the first slide or the last slide. If its on the first slide, then I'd hide the left arrow div and if it's on the last, I'd hide the right arrow, otherwise display both of em. Ive tried several ways to achieve this, but none of em work, so Ive resorted to using copies of variables from the function that works. Even then it does not work. It appears that my if and else if statements always evaluate to false, so perhaps I am not retrieving the position properly?
function HideArrows()
{
var wrapper2 = document.getElementById("VideoWrapper");
var offset_x2 = wrapper2.style.left;
if(parseInt(offset_x2,10) == max_x)
{
document.getElementById("NavigationForward").display = 'none';
}
else if(parseInt(offset_x2,10) == min_x)
{
document.getElementById("NavigationBackward").display = 'none';
}
else
{
document.getElementById("NavigationForward").display = 'inline-block';
document.getElementById("NavigationBackward").display = 'inline-block';
}
}
//html is the same except that I added a mouseover = "HideArrows();"
<div id = "ShowReelContainer" onmouseover="HideArrows();">
To achieve this type o slider functionality your div VideoWrapper must have overflow:hidden style, and your SlideShowItemdivs must have a position:relative style.
Then to move the slides forward or backward you can use the style left which allows you to move the divs SlideShowItem relative to it's parent VideoWrapper.
I've tested this here on JSFiddle.
It seems to work as you described in your question, although you may need to do some adjustments, like defining the width of your slides, how many they are and so on.
For the sake of simplicity, I defined them as "constants" on the top of the code, but I think you can work from that point on.
CSS
#VideoWrapper{
position:relative; height:100px; white-space:nowrap;width:500px;
margin-left:0px; border:1px solid #000; overflow:hidden; }
.SlideShowItem{
width:500px; height:100px;display:inline-block;position:relative; }
#NavigationForward, #NavigationBackward{
cursor:pointer;float:left; background-color:silver;margin-right:5px;
margin-bottom:10px; text-align:center; padding:10px; }

After you analyze and test the code, I don't really know what's your purpose with this, I mean, you maybe just playing around or trying to develop something for a personal project, but if you are looking for something more professional avoid to create things like sliders on your own, as there are tons of plugins like this available and well tested out there on the web.
Consider using jQuery with NivoSlider, it works like a charm and is cross browser.
I would recommend using jQuery, this will reduce your coding by quite a bit. Can read more here: http://api.jquery.com/animate/
I've created a simple fiddle for you to take a look at. This example uses the .animate() method to reposition two div elements based on the CSS 'left' property.
CSS:
#container {
position: absolute;
left: 1em;
top: 1em;
right: 1em;
bottom: 1em;
overflow: hidden;
}
#one, #two {
position: absolute;
color: white;
}
#one {
background: pink;
width: 100%;
top:0;
bottom:0;
}
#two {
background: blue;
width: 100%;
left: 100%;
top:0;
bottom:0;
}
HTML:
<div id="container">
<div id="one">Div One</div>
<div id="two">Div Two</div>
</div>
JavaScript/jQuery:
var one, two, container;
function animateSlides(){
one.animate({
left : '-100%'
}, 1000, function(){
one.animate({
left : 0
}, 1000);
});
two.animate({
left : 0
}, 1000, function(){
two.animate({
left:'100%'
}, 1000);
});
};
$(function(){
one = $('#one');
two = $('#two');
container = $('#container');
setInterval(animateSlides, 2000);
});
