I try to find a way to execute script after load dynamic script,
but I don't know How can I do that, and I hope to find help to solve this issue
my example:
index.html
<!DOCTYPE html>
<html>
<head>
<script src="./script/dynamic.js"></script>
<script>
$(document).ready(function () {
$("button").click(function () {
$("div").animate({
left: '250px',
height: '+=150px',
width: '+=150px'
});
});
});
</script>
</head>
<body>
<button>Start Animation</button>
<p>By default, all HTML elements have a static position, and cannot be moved. To manipulate the position, remember
to first set the CSS position property of the element to relative, fixed, or absolute!</p>
<div style="background:#98bf21;height:100px;width:100px;position:absolute;"></div>
</body>
</html>
dynamic.js
let myScript = document.createElement("script");
myScript.setAttribute("src", "./jquery/jquery-3.6.0.min.js");
document.head.appendChild(myScript);

As you may know, I'm very new to HTML and JS.
I tried to make an image move when you click on it, but for a some reason it doesn't work. Can someone take a look at it?
(It's my first day of learning Javascript! Please keep this in mind)
Javascript
var main = function() {
$('document.Image').click(function() {
$(this).animate({
left: "100px"
}, 200);
});
};
HTML
<html>
<head>
<title>JS Test</title>
</head>
<body>
<img height="25px" width="25px" src="https://webdesignfromscratch.com/snippets/html-css-javascript.gif">
<script type="text/javascript" src="app.js"></script>
</body>
</html>
You need to invoke/call main function
documemt.Image was invalid selector. Give class as .image to element which can be selected using $('.image')
To apply left css property in .animate(), element must be absolute/relative/fixed positioned. Review the updated css
var main = function() {
$('.image').click(function() {
$(this).animate({
left: "100px"
}, 200);
});
};
main();
.image {
position: absolute;
left: 200px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<img class='image' height="25px" width="25px" src="https://webdesignfromscratch.com/snippets/html-css-javascript.gif">
there is multiple mistake in your code... here is the code.
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>
<script>
$(document).ready(function(){
$('img').click(function(){
$(this).animate({'margin-left': "300px"})
});
});
</script>
</head>
<body>
<img style='margin-left:100px' src='' alt='no image' />
</body>
</html>
i m sure it helps u...
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
if (document.getElementById("popup")) {
window.alert("hi");
}
</script>
</head>
<body>
<h1 id="popup">dfdfs</h1>
</body>
</html>
i have a simple javascript which shows alert when the h1 id exits ,but i am not getting the alert message.code in jquery also can help.
Put your <script> tag at the end of the body:
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<h1 id="popup">dfdfs</h1>
<script type="text/javascript">
if (document.getElementById("popup")) {
window.alert("hi");
}
</script>
</body>
</html>
Write your script after the element so that it runs after element is present. See the code:
<!DOCTYPE html>
<html>
<body>
<h1 id="popup">dfdfs</h1>
<script type="text/javascript">
if (document.getElementById("popup")) {
window.alert("hi");
}
</script>
</body>
</html>
Plunkr for the same is: "http://plnkr.co/edit/0fznytLHtKNuZNqFjd5G?p=preview"
Because, you're executing the script before document is completely loaded, the element #popup is not found.
Use DOMContentLoaded
Use DOMContentLoaded to check if the DOM is completely loaded.
<script type="text/javascript">
document.addEventListener("DOMContentLoaded", function(event) {
console.log("DOM fully loaded and parsed");
if (document.getElementById("popup")) {
window.alert("hi");
}
});
</script>
Using jQuery ready
Using jQuery, you can use ready method to check if DOM is ready.
$(document).ready(function() {
if ($("#popup").length) {
window.alert("hi");
}
});
Moving script to the end of body
You can move your script to the end of body.
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<h1 id="popup">dfdfs</h1>
// Move it here
<script type="text/javascript">
if (document.getElementById("popup")) {
window.alert("hi");
}
</script>
</body>
</html>
Your script is above the h1 element that you're trying to retrieve. Because of this, it is being run before the element actually exists.
Either move the script to the bottom of the page, or wrap it in a jQuery ready block. And consider moving it to an external file.
$(function() {
if(document.getElementById("popup")) {
window.alert("hi");
}
});
try this easy way. no need of jquery.
<html>
<head>
</head>
<body>
<h1 id="popup">dfdfs</h1>
<script type="text/javascript">
if(document.getElementById("popup")) {
window.alert("hi");
}
</script>
</body>
</html>
It is good practice to use the <script> tags in <body> because it improves the performance by loading it quicker.
And then use
<body>
<script>
$(function() {
if(document.getElementById("popup")) {
window.alert("hi");
}
});
</script>
</body>
Below code gives you solution
$(document).ready(function() {
if (document.getElementById("popup")) {
window.alert("hi");
}
});
Alright so I'm pretty new to JavaScript coding in particular and have only been working with HTML and CSS for a few months so I apologize if this comes off as ridiculously simple.
I'm trying to use basic embedded JavaScript (jquery) to get a hyperlink to move to a new position each time you mouse over it, kind of like a cat following a laser-pointer dot.
When I run this code, the "moveAway" method doesn't appear to move the link at all when it is being hovered over. Just wondering if anyone could help identify the problem here:
<html>
<head>
<!-- Sheet references -->
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.6/jquery.min.js"></script>
</head>
<body>
<div id="link">
Click!
</div>
<script>
function moveAway()
{
$('#link').moveTo(0,100);
}
$('#link').hover(moveAway);
</script>
</body>
</html>
Do you wanna do something like this?
You can use left and top random too.
More information in Jquery documentation
<html>
<head>
<!-- Sheet references -->
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.6/jquery.min.js"></script>
</head>
<body>
<style>
#link
{
position:absolute;
}
</style>
<div id="link">
Click!
</div>
<script>
function moveAway()
{
$('#link').animate({
left: "+=50",
top: "+=50"
});
}
$('#link').hover(moveAway);
</script>
</body>
</html>
$('#link').hover(function(e) {
$(this).css('top', '0px');
$(this).css('left', '100px');
$(this).css('position', 'absolute');
});
I'm not sure if that's what you want.
See : http://jsfiddle.net/MHzYF/
You can make it a little fun by intro ducting Math.random() to generate x and y coordinates, and use jQuery's animate method. You can replace 100 with whatever offset you like.
jQuery
$('#link').on('mouseover', function(){
x = Math.floor((Math.random()*100)+1);
y = Math.floor((Math.random()*100)+1);
$(this).animate({
top: x,
left: y
});
});
HTML
Click!
CSS
#link { position: absolute; }

I am trying to make a mouse effect with a gif file and I found the following code:
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js">
</script>
<script>
$(function(){
$("body").mousemove(
function(e){
$("<img src='http://www.favicon.cc/logo3d/618187.png' />")
.css({
'position':'absolute',
'top':e.pageY+5,
'left':e.pageX+-15,
'width':'30px',
'height':'30px'
}).prependTo( $(document.body))
.fadeOut(100, 'linear', function(){
$(this).remove();
});
});
});
</script>
</body>
When I ran the html file I cannot see anything, for it, I think I am making a mistake in the code, Could anybody help me to fix?
Attach the mouse listener to $(document) instead of $('body').
Also in your code you are missing your closing </head> and start <body> tag (that you were using in the selector).
Demo here
While you have few errors in the code, it works fine.
The reason you don't see anything in firefox is that the body of the HTML is empty and the stars won't show up unless there's content.
It works fine on chromium and rekonq.
Just add content, and it will work fine
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js">
</script>
<script>
$(function(){
$(function(){
$("html").mousemove(
function(e){
for(i = 0; i < 5; i++){
$("<img src='http://www.favicon.cc/logo3d/618187.png' id='hover_" +i+"' />")
.css({
'position':'absolute',
'top':e.pageY+i*5,
'left':e.pageX+i*10,
'width':'30px',
'height':'30px'
}).prependTo( $(document.body))
.fadeOut(100, 'linear', function(){
$(this).remove();
});
}
});
});
});
</script>
</head>
<body>
<h1> Add content </h1>
<p> some content </p>
</body>
</html>
Test jsfiddle
you can change the dimensions as you want. If you want you can create an array with the given dX and dY changes and use that to position the images.

EDIT I Found the solution! credit goes entirely to the assistance I received from Mixel. For those who find themselves in the same predicament of needing to pull a div from an iframe without using onload here is the entire working code that I am using:
<html>
<head>
<title>Main page</title>
<style type="text/css">#hiddenframe {display:none;}</style>
<script type="text/javascript">
window.onload = function () {
var myUrl = "test.html"
document.frames['hiddenframe'].location.href = myUrl;
}
</script>
</head>
<body>
<div id="parent-div"></div>
<iframe id="hiddenframe"></iframe>
</body>
</html>
And the Child Page:
<html>
<head>
<title>Child Page</title>
<script type="text/javascript">
window.onload = function () {
parent.document.getElementById('parent-div').innerHTML = document.getElementById('daughter-div').innerHTML;
}
</script>
</head>
<body>
<div id="daughter-div">
This is the Child Div!
</div>
</body>
</html>
Thank you once again to Mixel for his help and patience in finding a solution
That's because you reload hiddenframe in onload handler. Reloading triggers onload event, then onload handler reloads hiddenframe. And this happens again and again...
Edit:
May be I do not understand what you want to do in your code, but if you want to load iframe when parent window is loaded you need this:
window.onload = function () {
document.getElementById('hiddenframe').setAttribute('src', 'test.html');
}
And there is window.onload handler of test.html page:
window.onload = function () {
parent.document.getElementById('parent-div').innerHTML = document.getElementById('daughter-div').innerHTML;
}
Edit2:
That's html of main page:
<div id="parent-div"></div>
<iframe id="hiddenframe">
</iframe>
And that's test.html:
<div id="daughter-div">
Child div!
</div>
