I'm working on a page that has a div with the id "exam" and a button with the id "copy". The div includes the text "Exam 1" and has a 2px double black border around it. When the button is clicked, the div element is supposed to be duplicated and displayed below each time the button is clicked. I have gotten that part to work, however, it doesn't seem to be copying the div element's CSS, only the text inside the element, so each time I click the button, it's only displaying "Exam 1", but not the border.
Here is my HTML (this also includes the Javascript and CSS):
<html>
<head>
<title>Exam 1 Tanner Taylor</title>
<style type="text/css">
#exam {
border: 2px double black;
}
</style>
</head>
<body>
<div id="exam">
Exam 1
</div>
<input type="button" id="copy" value="Make Copy" onclick="copy()" >
</body>
<script type = "text/javascript">
var TTi = 0;
var TToriginal = document.getElementById("exam");
function copy() {
var TTclone = TToriginal.cloneNode(true);
TTclone.id = "exam" + ++TTi;
TToriginal.parentNode.appendChild(TTclone);
}
</script>
</html>
There's more to it, but I cut out the portions that didn't deal with this particular issue. Any ideas as to why it's not displaying the border around the text when the button is clicked?
The css is only targeting the id exam and all clones are changing that id. A possible solution would be to use [id^="exam"].
^= says if it starts with "exam" then use this style.

<div id="exam">

var TToriginal = document.getElementById("exam");
function copy() {
var TTclone = TToriginal.cloneNode(true);
TTclone.id = "exam" + ++TTi;

I have created a webpage with a button. When you click it, it turns from the default black to pink and when you click it again, it turns purple. For some reason, it is taking two clicks to turn from the default black button to pink. Please help me figure out how to make it so it changes on the first click (or if you know a better way to carry this out)
HTML
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Events Lab</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<h1 id="changeh1"> Clicking the button will change its color <h1>
<button onclick="changeStyle()" type="button" name="button" id="buttonStyle">My color will change!</button>
<script src="script.js"></script>
</body>
</html>
JavaScript
function changeStyle() {
//sets variable "button" to connect to HTML ID "buttonStyle"
var button = document.getElementById("buttonStyle"),
click = false;
button.onclick = function() {
click = !click;
//toggles background color back and forth between pink and purple when you click button
button.style.background = click? "#ff0066": "#9933ff";
//toggles text back and forth between "I am now pink!" and "I am now purple!"
document.getElementById('buttonStyle').innerHTML = click? 'I am now pink!': 'I am now purple!';
}
}
let buttonClick = document.getElementById('buttonStyle');
buttonClick.addEventListener('click', changeStyle);
CSS
body{
text-align: center;
font-family: Helvetica;
}
button {
width:350px;
height: 125px;
background-color: black;
color:white;
border: 5px solid black;
font-size: 20px;
}
In your javascript, you wrote the below codelines.
let buttonClick = document.getElementById('buttonStyle');
buttonClick.addEventListener('click', changeStyle);
Also in your html you wrote the code like the below.
<button onclick="changeStyle()" type="button" name="button" id="buttonStyle">My color will change!</button>
Meaning, when you click the My color will change! button, the changeStyle function will be called twice.
Why?
One from the event defined in html code and the other one from the event defined in javascript code.
In case you remove the above 2 codelines in javascript it will work correctly.
Or else, you can remove the onclick event in the html code like this :
<button type="button" name="button" id="buttonStyle">My color will change!</button>
You added eventListener two times, one in HTML onclick, the other one in Javascript with addEventListener.
You can make Javascript code as simple as follows:
var click = false;
let buttonClick = document.getElementById('buttonStyle');
function changeStyle() {
click = !click;
//toggles background color back and forth between pink and purple when you click button
buttonClick.style.background = click? "#ff0066": "#9933ff";
//toggles text back and forth between "I am now pink!" and "I am now purple!"
buttonClick.innerHTML = click? 'I am now pink!': 'I am now purple!';
}
body{
text-align: center;
font-family: Helvetica;
}
button {
width:350px;
height: 125px;
background-color: black;
color:white;
border: 5px solid black;
font-size: 20px;
}

css javascript style sheet disabled?
(3 answers)
Closed 4 years ago.
I have an question about modify the tag type attribute problem. In my case, I want to dynamicly change the type to make it work or disabled.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<style r = "1" type = "text/css">
h1 {
font-size: 20px;
}
</style>
<style r = "2" type = "not work">
h1 {
font-size: 40px;
}
</style>
</head>
<body>
<script>
var style1 = document.querySelector('[r="1"]')
var style2 = document.querySelector('[r="2"]')
</script>
<h1>this text can be either 20px or 40px</h1>
<input type="button" value="make text 20px" onclick = "style1.type='text/css';style2.type='not work'">
<input type="button" value="make text 40px" onclick = "style2.type='text/css';style1.type='not work'">
</body>
</html>
So here's the example : click me
It works on chrome, but nor work in ie11, safari. Anybody can help ? Thanks a lot.
Addition: What i am doing is to change page style depends on some condition, say: language. In some reason I cant use mvvm framework.
That's not how you do it, actually. It's bad practice to change styles this way. It's better to change just one element style and not whole page style
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<style type = "text/css">
h1 {
font-size: 20px;
}
</style>
</head>
<body>
<script>
function changeStyle(fontSize) {
var heading = document.querySelector('h1')
heading.style.fontSize = fontSize;
}
</script>
<h1>this text can be either 20px or 40px</h1>
<input type="button" value="make text 20px" onclick = "changeStyle('20px')">
<input type="button" value="make text 40px" onclick = "changeStyle('40px')">
</body>
</html>
Is there any change to have input element similar like is on my screenshot.
I would like to change value via javascript and highlight part of text with different color if it will be wrapped with *
Thanks for any help.
You cannot do it with an input element. Here is one alternative:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>JS Bin</title>
<style>
/*style it to look like input element*/
[contenteditable] {
border: 1px solid gray;
}
</style>
</head>
<body>
<div id="contentDiv" contenteditable>sdfsdtokendfdfsdfs</div>
<br/>
<input type="button" onclick="test()" value="Click me"/>
<script type="text/javascript">
function test() {
// this is our token
var valueToSelect = "tokendfdf";
var contentDiv = document.getElementById('contentDiv');
// check if div contains wanted token
if (contentDiv.innerHTML.indexOf(valueToSelect) >= 0) {
// create span with wanted color
var replaceString = '<span style="color: red">*' + valueToSelect + '*</span>';
// replace the string with colored span
contentDiv.innerHTML = contentDiv.innerHTML.replace(valueToSelect, replaceString);
}
}
</script>
</body>
</html>
Here is JS Bin example
Following is the html-javascript code for setting the background image and background image.
<html>
<link rel="stylesheet" type="text/css" href="try2.css">
<body>
Choose the color<br>
<div class="foo" id="#13b4ff" style="background-color:#13b4ff;"></div>
<div class="foo" id="ab3fdd" style="background-color:#ab3fdd;"></div>
<div class="foo" id="ae163e" style="background-color:#ae163e;"></div>
<br><br>
<div id="myframe1" style="padding:5px;width:300px;height:400px;border:1px solid black;">
<p><img src="img-thing.png" style="width:200px;height:200px;"/><p>
</div>
<script type="text/javascript" src="http://jqueryjs.googlecode.com/files/jquery-1.3.2.min.js"> </script>
<script type="text/javascript">
$(document).ready(function(){
$('.foo').click(function(){
var str1 = $(this).attr('id');
var myframe = document.getElementById('myframe1');
myframe.style.backgroundColor=str1;
myframe.style.width=300;
myframe.style.height=400;
});
});
</script>
<div><input type='file' onchange="readURL(this);" />
<img id="blah"/></div>
<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
<script type="text/javascript">
function readURL(input) {
if (input.files && input.files[0]) {
var reader = new FileReader();
reader.onload = function (e) {
$('#myframe1').css({
'background':'url('+e.target.result +')',
'background-size':'310px 410px'
});
};
reader.readAsDataURL(input.files[0]);//To display images uncomment this
}
}
</script>
</body>
</html>
The CSS FILE FOR COLORS IS(just in case you need to look at that as well)
.foo {
float: left;
width: 20px;
height: 20px;
margin: 5px 5px 5px 5px;
border-width: 1px;
border-style: solid;
border-color: rgba(0,0,0,.2);
}
Now the problem is:
I want that user may click upload image option first and upload the image as a background. But once that is done it not allowing user to se color as a background. How to fix that? On the contrary if color is choosen and then image, image can override as background.I want that both must be able to override each other. For convenience I also the fiddle link : here Also one more issue in the fiddle, other colors are not showing up, but they are working in my html file.
First of all correct your id name of class foo . use # in all ids ok
next empty the background of the div while on clicking of color div by
myframe.style.background="";
: Here is your corrected working code now
I think you can achieve by adopting two DIVs, one of them is used to render background images and the other render background color.
By changing 'z-index' of DIV, you can display COLOR at top or bottom.
Hope this can help you .
The following code should work under mainstream browser.
Take a try.

I'd like to display a div on a webpage when a user clicks on a button.
Does someone know how to do this ?
My code, so far, is :
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso 8859-1" />
</head>
<body>
<input id="text" type="text" size="60" value="Type your text here" />
<input type="button" value="When typing whatever text display the div balise on the page" onclick="check();" />
<script type="text/javascript">
function check() {
//Display my div balise named level0;
}
</script>
</body>
</html>
Thanks,
Bruno
EDIT: All my code (I've erased it because it was too long and not very clear)
You can use document.createElement("div") to actually make the div. Then you can populate the div using innerHTML for the text. After that, add it to the body using appendChild. All told, it can look like this:
function check() {
var div = document.createElement("div");
div.innerHTML = document.getElementById("text").value;
document.body.appendChild(div);
}
This will add a div every time the button is pressed. If you want to update the div each time instead, you can declare the div variable outside the function:
var div;
function check() {
if (!div) {
div = document.createElement("div");
document.body.appendChild(div);
}
div.innerHTML = document.getElementById("text").value;
}
If you have the div already in the page with an id of "level0", try:
function check() {
var div = document.getElementById("level0");
div.innerHTML = document.getElementById("text").value;
}
A quick search on google gave me this example:

The source-code for that example is:

border: #0000cc 2px dashed;
display: none;
}
</style>
<script language="JavaScript">
function setVisibility(id, visibility) {
document.getElementById(id).style.display = visibility;
}
</script>
</head>
<body>
<input type=button name=type value='Show Layer' onclick="setVisibility('sub3', 'inline');";><input type=button name=type value='Hide Layer' onclick="setVisibility('sub3', 'none');";>
<div id="sub3">Message Box</div>
<br><br>
</body>
</html>
Paste this code somewhere in your body
<div id="myDiv" style="display:none">
Hello, I am a div
</div>
Add this snippet into your check() function to display the otherwise-hidden content.
document.getElementById("myDiv").style.display = "block";
You could also change the div content programmatically thus:
document.getElementById("myDiv").innerHTML = "Breakfast time";
... would change the text to 'Breakfast time'.
You might want to look into jquery, it'll make your life 100 times easier.
Jquery is a javascript library (script) that you include and it allows you to manipulate the DOM very easily.
Start by adding the latest Jquery to your head which will allow you to use something like $(document).ready( )
The function inside .ready( fn ) is a callback function; it get called when the document is ready.
$("#lnkClick") is a selector (http://api.jquery.com/category/selectors/)
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready( function() {
$("#lnkClick").click( function() {
$("#level0").attr("style", "display: block;width: 100px; height: 100px; border: solid 1px blue;");
});
});
</script>
</head>
<body>
<div id="level0" style="display:none;">
</div>
Click me
</body>
</html>
Of course this code can be made cleaner. You want to check: http://api.jquery.com/click/
There are plenty of examples.
Best of luck with Jquery!
you really should be using jquery , there's a little bit of a learning curve but once you get it, developing web apps is much easier.
<html>
<head>
<script src="http://code.jquery.com/jquery-1.5.2.min.js"></script>
<script>
$(document).ready(function() {
$("#show_div_button").click(function() {
$("#div_to_show").show();
return false;
});
});
</script>
</head>
<body>
Click Me to Show the Div
<div style="display:none" id="div_to_show">I will be shown when the link is clicked</div>
