How to execute a javaScript url when a visitor clicks inside div
Like this example :
<html>
<head>
<meta charset="UTF-8">
<style>
.youtube .play,.youtube img{cursor:pointer;position:absolute}
.youtube{position:relative;padding-bottom:56.23%;height:0;overflow:hidden;max-width:100%;background:#000;margin:5px}
.youtube embed,.youtube iframe,.youtube object{position:absolute;top:0;left:0;width:100%;height:100%;z-index:100;background:0 0}
.youtube img{bottom:0;display:block;left:0;margin:auto;max-width:100%;width:100%;right:0;top:0;border:none;height:auto;-webkit-transition:.4s all;-moz-transition:.4s all;transition:.4s all}
.youtube img:hover{-webkit-filter:brightness(75%)}
.youtube .play{height:72px;width:72px;left:50%;top:50%;margin-left:-36px;margin-top:-36px;background:url(//i.imgur.com/TxzC70f.png) no-repeat}
</style>

<body>
<div class="youtube" data-id="YQHsXMglC9A"></div>
</body>
<script>
/* Light YouTube Embeds by #labnol */
/* Web: http://labnol.org/?p=27941 */
document.addEventListener("DOMContentLoaded",
function() {
var div, n,
v = document.getElementsByClassName("youtube");
for (n = 0; n < v.length; n++) {
div = document.createElement("div");
div.setAttribute("data-id", v[n].dataset.id);
div.innerHTML = labnolThumb(v[n].dataset.id);
div.onclick = labnolIframe;
v[n].appendChild(div);
}
});
function labnolThumb(id) {
var thumb = '<img src="https://i.ytimg.com/vi/ID/hqdefault.jpg">',
play = '<div class="play"></div>';
return thumb.replace("ID", id) + play;
}
function labnolIframe() {
var iframe = document.createElement("script");
iframe.setAttribute("src", "https://www.youtube.com/embed/" + this.dataset.id + "?autoplay=1");
iframe.setAttribute("frameborder", "0");
iframe.setAttribute("allowfullscreen", "1");
this.parentNode.replaceChild(iframe, this);
}

Html code + javascript :
<!doctype html>
<html>
<head>
<meta charset="utf-8">
</head>
<body>
<div id="a" style="background-color:#999; height:90px; width:250px;" >Click here</div>
</body>
</html>
Javascript :
<script type="text/javascript">
document.write("Hello World!");
</script>
Or :
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
How do I run javaScript url when a visitor clicks inside div ?
Something liked this would do it...
function clickMe() {
alert("You clicked me!")
}
<!doctype html>
<html>
<head>
<meta charset="utf-8">
</head>
<body>
<div id="a" style="background-color:#999; height:90px; width:250px;" onclick="clickMe()" >Click here</a></div>
</body>
</html>
First of all, instead of trying to run a script, you should try to run a function.
For example
function test(){
document.write("Hello World!")
}
function test2(){
document.getElementById("output").innerHTML = "Hello World!"
}
<div onclick="test()">
<p> Click me </p>
</div>
<div onclick="test2()">
<p> Click me (won't remove screen) </p>
</div>
<div id="output">
</div>
Clicking on the first div will call the test() function. This function will however overwrite everything on the screen, that's not what you want.
The second method doesn't do that, instead it sets the content of the third div to "Hello World!"
I believe you want to run a JavaScript function when your div gets clicked. You just need to add an onclick() event to your <div> tag and declare that function. So your div would be something like this:
<div id="a" style="background-color:#999; height:90px; width:250px;" onclick="writeFunction();">Click here</div>
And the function, with the same name as you declared on your onclick:
<script type="text/javascript">
function writeFunction(){
document.write("Hello World!");
}
</script>
As you have used document.write and i have kept that, it does not show the result that you have illustrated in your picture and your div is vanishing. In order to do as you have imagined, you have to add a <p> element which is initally blank:
<p id='text'></p>
and then ask your function to set its text, like this:
document.getElementById('text').innerHTML = "Hello World!";

i am trying to create this <div id="myid" >Hello Wordl!</div> in the body of the page but my code problem is , after waiting 10 seconds it will replace this <div id="myid" >Hello Wordl!</div> with whole content of my page so it will only show this div.
here's my javascript code
<script>
setTimeout(function(){
$("body").prepend("<div id='myid'>hello world</div>");
},10000);
},10000);
</script>
and my page is like this
<html>
<head>
<style type="text/css">
body {margin:0;padding:0;}
</style>
<title></title>
</head>
<body>
<script>
setTimeout(function(){
$("body").prepend("<div id='myid'>hello world</div>");
},10000);
</script>
<!-- New div created by javascript must be here -->
<div id="1">Keep This Div</div>
</body>
</html>
Working Code
<html>
<head>
<script src="https://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.2.1.min.js"></script>
<style type="text/css">
body {margin:0;padding:0;}
</style>
<title></title>
</head>
<body>
<script>
setTimeout(function(){
$("body").prepend("<div id='myid'>hello world</div>");
},10000);
</script>
<!-- New div created by javascript must be here -->
<div id="1">Keep This Div</div>
</body>
</html>
If you want to add an element to your html body you can just create it and then append it like this:
var elemDiv = document.createElement('div');
document.body.appendChild(elemDiv);
You can then add attributes and also innerHTML via Javascript like this:
elemDiv.id = 'myid';
elemDiv.innerHTML = 'Hello World!'
Nothing is overwritten in your code. You try to create element (in wrong way) and do nothing with it.
<div id="id1">Keep This Div</div>
<script>
setTimeout(function() {
var el = document.createElement('div');
el.id = 'myid';
el.innerHTML = 'Hello World!';
document.getElementById('id1').prepend(el);
}, 2000);
</script>
Note that id="1" is invalid value, I've changed it to id1 in my example.
I Have the following code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<script>
function myEvent(){
if(document.getElementById('demo2').innerHTML=="Hide Me"){
document.getElementById('demo1').src='none';
document.getElementById('demo2').innerHTML='Display Me';
}
else {
document.getElementById('demo1').src="deepika.jpg";
document.getElementById('demo2').innerHTML="Hide Me";
changeCSS();
}
}
function changeCSS(){
document.getElementById('demo1').style.height="500";
document.getElementById('demo1').style.width="400";
}
</script>
</head>
<body>
<img src="deepika.jpg" id="demo1" height="500" width="400"><br>
<button type="button" id="demo2" onclick=myEvent()>Hide Me</button>
</body>
</html>
After clicking on Hide Me button I get this page:
Now I want to completely remove the picture block and bring Display Me button to top of the page. How can I do so?
I want to use plain JavaScript only and no JQuery
If I understand the question properly, you want to toggle the display of image upon button click. You can use the below updated myEvent function:
function myEvent(){
if(document.getElementById('demo2').innerHTML=="Hide Me"){
document.getElementById('demo1').src='none';
document.getElementById('demo1').style.display = "none";
document.getElementById('demo2').innerHTML='Display Me';
}
else {
document.getElementById('demo1').style.display = "";
document.getElementById('demo1').src="deepika.jpg";
document.getElementById('demo2').innerHTML="Hide Me";
changeCSS();
}
}
I created this code so my page would be hidden until it finishes loading. But my code doesn't work as I expected. I expected this to hide the BODY until the OnLoad event was triggered.
However, instead, it just stays hidden.
Any help would be appreciated, if there is maybe another, better method of hiding the BODY until it finishes loading, or what's wrong with this one.
Here's what I've tried so far:
function unveil() {
var thebod = document.getElementById("testbody");
thebod.STYLE = "display: block;"
}
<HTML>
<HEAD>
<TITLE>HELLO</TITLE>
</HEAD>
<BODY ID="testbody" ONLOAD="unveil();" STYLE="display: none;">
<div align="CENTER">
HELLO WORLD!
</div>
</BODY>
</HTML>
The DOMContentLoaded event of the window object can do this. But, don't hide the body, hide a wrapper instead. And, when you set the style, make sure to set the style of a CSS property, not the style object itself.
window.addEventListener("DOMContentLoaded", function(){
document.getElementById("wrapper").style.display = "block";
});
#wrapper { text-align:center; background:#e0e0e0; display:none;}
<HTML>
<HEAD>
<TITLE>HELLO</TITLE>
</HEAD>
<BODY>
<div id="wrapper">
HELLO WORLD!
<!-- The following is only added to create a delay in the
parsing of the document -->
<script>
for(var i = 0; i < 100000000; ++i){ var x = i / 3.14; }
</script>
</div>
</BODY>
</HTML>
You're not setting the elements 'style' correctly:
You can either do:
element.style.display = "block";
Or
element.setAttribute('style', "display: block");
Here is a working example:
function unveil() {
var thebod = document.getElementById("testbody");
thebod.style.display = "block";
}
<HTML>
<HEAD>
<TITLE>HELLO</TITLE>
</HEAD>
<BODY ID="testbody" ONLOAD="unveil();" STYLE="display: none;">
<div align="CENTER">
HELLO WORLD!
</div>
</BODY>
</HTML>
Your issue is here:
thebod.STYLE = "display: block;"
which should read:
thebod.style.display = 'block';
Here is the complete approach (using unobtrusive javascript):
var body = document.getElementsByTagName('body')[0];
function unveil() {
body.style.display = 'block';
}
window.addEventListener('load', unveil, false);
body {
display: none;
}
div {
text-align: center;
}
<div>HELLO WORLD!</div>
<HTML>
<HEAD>
<TITLE>HELLO</TITLE>
</HEAD>
<BODY ID="testbody" onload="testbody.style.display = '';" style="display: none;">
<div align="CENTER">
HELLO WORLD!
</div>
</BODY>
</HTML>
I'm working on an application with modal overlays that appear within iFrames when the corresponding buttons are pressed. To close one of these modal overlays, the Cancel button is defined in the parent window this way:
Cancel
I'd like to replace this with a JavaScript function (let's call it onCancel() ) so I can reset some values if needed in addition to closing the overlay. What is the JavaScript equivalent to "#close"?
You can't close an iFrame, you either have to remove or hide it. The example below removes the iframe. If you just want to hide you can replace the last line (containing removeChild with this one frame.style.display="none"; You can then get it back by using this line frame.style.display="block";
<!DOCTYPE html>
<head>
<title>test</title>
<style type="text/css">
.top {
height: 100px;
width: 200px;
background-color: blue;
}
</style>
<script type="text/javascript">
function removeIFrame() {
var frame = document.getElementById("iframe");
frame.parentNode.removeChild(frame);
}
</script>
</head>
<body>
<div class="top" onclick="removeIFrame();"></div>
<iframe id="iframe" src="/" width="200" height="100"></iframe>
<div class="top"></div>
</body>
<!DOCTYPE html>
<head>
<title>test</title>
<style type="text/css">
.top {
height:100px;
width:200px;
background-color:green;
}
</style>
<script type="text/javascript">
function removeIFrame() {
var frame = document.getElementById("target");
frame.parentNode.removeChild(frame);
}
</script>
</head>
<body>
<div class="top" onclick="removeIFrame();"></div>
<iframe id="target" src="http://www.disney.com" width="100" height="100"></iframe>
<div class="top"></div>
</body>
The approach that works for me is to define the following JavaScript function in the parent page:
function onCancel()
{
var myIFrame = document.getElementById("myIFrame");
var myForm = myIFrame.contentDocument.myForm;
var stuffWasChanged = myIFrame.contentDocument.stuffWasChanged;
if (stuffWasChanged == "true")
myForm.action = "reset.do";
myForm.submit();
location.href = '#';
}
Note that if the stuffWasChanged flag was not set to true, then no action is defined for the form in question, so the modal overlay simply goes away without any servlet method being called.
This is inside my CSS:
div.hide {
display:none;
}
div.show {
color: #66CCFF;
}
This is in my HTML:
16:10
<script language="JavaScript">
function showText(show,hide)
{
document.getElementById(show).className = "show";
document.getElementById(hide).className = "hide";
}
</script>
<a name="16:10" onclick="showText('text1')" href="javascript:void(0);"></a>
<div id="text1" class="hide">This is your monitors aspect ratio.</div>
I'm trying to make the first link display the "This is your monitors aspect ratio." text lower on the page.
Any help is much appreciated.
Pure CSS Answer
Ok, if you just want to append text after you have moved to a position in a page using an anchor tag, you could do it with nothing but CSS similar to the following:
a:target:after{
content: " Test";
background-color: #ccffcc;
}
What this does is appends the text "Test" after the active anchor and colors. Here is an example page with implementation:
<!DOCTYPE html>
<html>
<head>
<title>Link Printer 2</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width">
<style>
a:target:after{
content: " Test";
background-color: #ccffcc;
}
.bigSection{
height: 200px;
}
</style>
</head>
<body>
<div class="bigSection">
<div><a name="first">First</a></div>
<div>To First</div>
<div>To Second</div>
<div>To Third</div>
</div>
<div class="bigSection">
<div><a name="second">Second</a></div>
<div>To First</div>
<div>To Second</div>
<div>To Third</div>
</div>
<div class="bigSection">
<div><a name="third">Third</a></div>
<div>To First</div>
<div>To Second</div>
<div>To Third</div>
</div>
</body>
</html>
Answer using JavaScript
You need to bind an eventListener and prevent it from moving to the next page. Here is a way to do it with JavaScript or CSS. The JavaScript way will actually set the text to whatever you want. The CSS way will hide actually hide the element.
<!DOCTYPE html>
<html>
<head>
<title>Link Printer</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width">
<style>
.hide{
display: none;
}
</style>
<script>
function jsShowText(event) {
var divToManip = document.getElementById("text");
if (divToManip.innerHTML === "") {
divToManip.innerHTML = "Hello";
}
else {
divToManip.innerHTML = "";
}
event.preventDefault();
}
function cssShowText(event) {
var divToManip = document.getElementById("text");
if (divToManip.className === "") {
divToManip.className = "hide";
}
else {
divToManip.className = "";
}
event.preventDefault();
}
function setListeners() {
document.getElementById("jsPrinter").addEventListener("click", jsShowText, false);
document.getElementById("cssPrinter").addEventListener("click", cssShowText, false);
}
window.onload = setListeners;
</script>
</head>
<body>
<div><a id="jsPrinter" href="" onclick="showText();">Click With JavaScript</a></div>
<div><a id="cssPrinter" href="" onclick="showText();">Click With CSS</a></div>
<div id="text">I'm text</div>
</body>
</html>
"showText" must receive an id parameter to be used with the call to "document.getElementById"
Try this, just 1 link that will display the text below after click:
<a name="16:10" onclick="showText('text1')" href="javascript:void(0);">16:10</a>
<script language="JavaScript">
function showText(id)
{
document.getElementById(id).style.display = "block";
}
</script>
<div id="text1" style="display:none;">This is your monitors aspect ratio.</div>
I'm just using style display to hide/show the element. Hope it helps.
just change your css like this:
div.show {
display:block;
color: #66CCFF;
}
Here I am going to provide an example with something that I was working, thank you Alberto Montellano for the example, that gave me an idea, however what was required at the end was something a little different, with the option not to show the data and display it only when I click and make it disappear when click again. In this example I am going to give you two options; you can have a button or a link to trigger the JS function to display and hide the body text, you can choose if you want the button or link that is way I put a comment (optional), both behave as the same, it is up to you which one you want to use.
<!DOCTYPE html>
<html>
<head>
<!-- CSS -->
<style>
#myDIV {
width: 100%;
padding: 50px 0;
text-align: center;
background-color: lightblue;
margin-top:20px;
}
</style>
</head>
<body>
<!-- text before the button or link -->
<p>Click the "PIN" button (or link) to display PIN options:</p>
<!-- The Pin button (optional) -->
<button type="button" onclick="myFunction()">PIN button:</button>
<!-- The Pin link (optional) -->
</br></br></br>
<a onclick="myFunction()" href="javascript:void(0);">PIN link:</a>
<!--Data will display or hide (toggle)-->
<div id="myDIV"style="display:none;">
These are the steps to get your PIN number: Bla bla bla.
</div>
<p><b>Note:</b> The text display when you click the button or link will take space, if you click again will be toggle.</p>
<!-- JS -->
<script>
function myFunction() {
var x = document.getElementById('myDIV');
if (x.style.display === 'none') {
x.style.display = 'block';
} else {
x.style.display = 'none';
}
}
</script>
</body>
