I want to call a partial html page using jquery. I have seen this
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<script type="text/javascript" src="lib/jquery-3.1.0.min.js"></script>
<script type="text/javascript"> $('#result').load('Ajax/test.html'); </script>
<title>Home</title>
</head>
<body>
<div id="result"></div>
</body>
</html>
and in the path Ajax/test.html i have this test.html:
<h1>Hey World</h1>
The problem is it does not load the Hey World into the main page. Also, there is no error in console.
What is the problem?
As with $('#result'), jQuery is unable to find the element as DOM is not ready hence jQueryObject.load method is never invoked.
Wrap your script in $(document).ready or Place your <script> as last-child of <body>(Just before closing body tag(</body>))
There are also DOMContentLoad or window.onload events which makes sure that DOM is loaded but IMO, placing <script> just before </body> is easier option.
<div id="result"></div>
<script>
$('#result').load('test.html');
</script>
You are trying to append to an element that yet does not exists.
Try adding your code in a $(document).ready(), and just before the </body> closing tag.
Like this:
<script>
$(document).ready(function(){
$('#result').load('Ajax/test.html');
});
</script>
</body>
Try changing your <script> tag to include a document.ready:
<script type="text/javascript">
$(document).ready(function () {
$('#result').load('Ajax/test.html');
});
</script>

Can someone help me? I wrote simple code in javascript and it wont work for some reason. I tried to figure out but i cant see why. I have downloaded jquery and it is all ok with it, also i tried only javascript code and still same problem. Browser is ok it load jquery and javascript on file i made earlier but doesnt load on this.Here is code:
<!DOCTYPE html>
<html>
<head>
<title>Proba</title>
<script src="jquery-3.3.1.js">
$('#btn').click(function f() {
console.log(1);
});
</script>
</head>
<body>
<button id="btn">Click</button>
</body>
</html>
<head>
<title>Proba</title>
</head>
<body>
<button id="btn">Click</button>
<script src="jquery-3.3.1.js"></script>
<script>
$(document).ready(function(){
$("#btn").click(function(
console.log(1);
))
})
</script>
</body>
Try like this :)
You are binding your event handler, before the browser was able to parse your HTML. So #btn element is not in the DOM yet at this point.
Either wrap you code inside document.ready or move the script to the bottom of the body tag.
1st Approach
<head>
<title>Proba</title>
<script src="jquery-3.3.1.js"></script>
<script>
$(function() {
$('#btn').click(function f() {
console.log(1);
});
});
</script>
</head>
<body>
<button id="btn">Click</button>
</body>
2nd Approach
<head>
<title>Proba</title>
<script src="jquery-3.3.1.js"></script>
</head>
<body>
<button id="btn">Click</button>
<script>
$('#btn').click(function f() {
console.log(1);
});
</script>
</body>
Have you verified "jquery-3.3.1.js" really exists in the current directory? Try instead loading the script through a known host, like Google:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
EDITED: Added working code. Note button checking must be done when document has finally loaded.
<!DOCTYPE html>
<html>
<head>
<title>Proba</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("#btn").click(function() {
console.log(2);
});
})
</script>
</head>
<body>
<button id="btn">Click</button>
</body>
</html>
I already fail at a seemingly basic task in javascript - changing a div's content by a script. Please help me understand where I am going wrong. Here is a minimal example that's not working for me:
<!DOCTYPE html>
<html>
<head>
<script>
document.getElementById('id').innerHTML = "test";
</script>
</head>
<body>
<div id="id" >blub</div>
</body>
</html>
The Problem with you code it that the JavaScript code is executed before the div part is loaded fully. To fix this change you code to:
<!DOCTYPE html>
<html>
<head>
<script>
function changeDiv()
{
document.getElementById('id').innerHTML = "test";
}
</script>
</head>
<body onload="changeDiv();">
<div id="id" >blub</div>
</body>
</html>
The onload event will only fire when the html is fully loaded.
HTML files load starting at the top to the bottom of the html.
In your example, the javascript executes before the <body> tag exists in the DOM.
Moving the javascript to below the relevant html makes it work as you would expect.
Another option would be to keep the script inside the <head> but delay it from executing until the DOM is loaded
window.onload = function() {
document.getElementById('id').innerHTML = "test";
};
https://developer.mozilla.org/en/docs/Web/API/GlobalEventHandlers/onload
<!DOCTYPE html>
<html>
<head></head>
<body>
<div id="id" >blub</div>
<script>
document.getElementById('id').innerHTML = "test";
</script>
</body>
</html>
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<div id="id" >blub</div>
<script>
document.getElementById('id').innerHTML = "test";
</script>
</body>
</html>
put your script after the div.
You need to use window.onload to call your code when html is fully loaded:
<!DOCTYPE html>
<html>
<head>
<script>
window.onload = function() {
document.getElementById('id').innerHTML = "test";
};
</script>
</head>
<body>
<div id="id" >blub</div>
</body>
</html>
Your Dom is no not loaded.. Place your script tag at the end before
Just add the script tag before closing the body. It'll work.
You have to write the Javascript after the div-Tag. First the DOM needs to be loaded and after you can change the content inside the DIV.
Place your Javascript before the closing-body Tag
I'm tring to use the command innerHTML to change the text of my HTML code. it works if I put it at the HTML file, but not if I put in an external one.
The one that works:
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<p id="Monkey">Monkey</p>
<script>
document.querySelector("#Monkey").innerHTML="NoMoreMonkeys";
</script>
</body>
</html
Output: NoMoreMonkeys
The one that doesn't:
<!DOCTYPE html>
<html>
<head>
<script src="hello.js"></script>
</head>
<body>
<p id="Monkey">Monkey</p>
</body>
</html>
File "hello.js" :
document.querySelector("#Monkey").innerHTML="NoMoreMonkeys";
Output: Monkey
Can someone help me?
You should include js before end of body,
because if js run before DOM ready, #Monkey did not exist.
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<p id="Monkey">Monkey</p>
<script src="hello.js"></script>
</body>
</html>
Or use jquery document ready:
$(document).ready(function() {
document.querySelector("#Monkey").innerHTML="NoMoreMonkeys";
});
The solution is to manipulate the page, when it is safe to do.
For that add jQuery to your page and let your JS code execute, when thh document is ready.
$( document ).ready(function() {
document.querySelector("#Monkey").innerHTML="NoMoreMonkeys";
});
or select element with jQuery as well:
$( document ).ready(function() {
$( "#Monkey" ).html("NoMoreMonkeys");
});
i have created a simple jQuery program.i am new to jQuery technology..please provide me where am i wrong?

The script you've written isn't supposed to go inside the jquery script tag. It needs to go in its own one.
<script type="text/javascript" src="jquery-1.4.2.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
alert("jQuery tutorial for beginners Example");
});
</script>
The first one is to load jquery itself - it's like saying "instead of me writing some javascript here, load it from this file instead", the second one is for your own code since you've put code between the script tags.
A script element can have one script. That script can go between the start tag and the end tag or it can go in another file and be referenced with a src attribute.
If there is a src attribute, then the content of the element will be ignored.
If you want two scripts, then you need two script elements.
<script src="jquery.js"></script>
<script>
// Your code
</script>
Example: Jsdiffle
This is a example with last library of Jquery.

For the above mentioned code click event is not firing. I used JSFiddle it works fine.
It works fine in case of delegation. The code I used for delegation is below
<!DOCTYPE HTML>
<html>
<head>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.7.2.js"></script>
<script type="text/javascript">
$(document).on("click","button",function(){
alert('myBtn Clicked');
});
</script>
</head>
<body>
<button type="button" id="myBtn">Sample</button>
</body>
Help me in solving this....
Read http://docs.jquery.com/How_jQuery_Works
So for you it would be:
$(document).ready(function(){
$("#myBtn").on("click",function(){
alert('myBtn Clicked');
});
});
Put your code inside document.ready()
<!DOCTYPE HTML>
<html>
<head>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.7.2.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("#myBtn").on("click",function(){
alert('myBtn Clicked');
});
});
</script>
</head>
<body>
<button type="button" id="myBtn">Sample</button>
</body>
</html>
Now in second case your code worked because document is loaded first in the page and attaching may be done to it without document.ready but at that time html element may be loading so event can't be attached to them
Try to put it on Initiliaze function. Maybe javascript of jquery is not loaded
$(function () {
$(document).on("click","button',function(){
alert('myBtn Clicked');
});
});
Simples: your DOM isn't loaded yet when you are adding the listeners! Make sure the DOM is loaded first by either
use the ready event
move the script tag to the end of your body
$( document ).ready(function(e) {
// add listeners here
});
