My code won't work. It's supposed to alert whenever a user presses a key while focused inside of a textbox element!
$("#yourcode").keyup(function() {
alert("I found Hogwarts.");
});
You need to wait until the DOM is ready before adding the keyup handler. This can be achieved by calling .ready() after using $() to get a DOM reference to the document (i.e. $(document)). Also make sure you load jQuery before you load the script:
JS:
<script
src="https://code.jquery.com/jquery-3.2.1.min.js"
integrity="sha256-hwg4gsxgFZhOsEEamdOYGBf13FyQuiTwlAQgxVSNgt4="
crossorigin="anonymous"></script>
<script>
$(document).ready(function(){
$("#yourcode").keyup(function() {
alert("I found Hogwarts.");
});
});
</script>
HTML:
<textarea id="yourcode"></textarea>
Here is a working example (also available in this jsFiddle):
$(document).ready(function(){
$("#yourcode").keyup(function() {
alert("I found Hogwarts.");
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<textarea id="yourcode"></textarea>

Optimized my website with WP Rocket and delayed javascript execution with some exclusions. Excluded: /jquery-?0-9.(.min|.slim|.slim.min)?.js and js-(before|after) and my script which has code:
jQuery(document).ready(function() {
console.log('F Loaded');
jQuery('#div_id').bind('click', function() {
jQuery('#desired_element').css('display','block');
console.log('Clicked')
});
});
When I'm loading a website - getting first message in console "F loaded", but after click - action happens only after all rest scripts are loaded. Is there any way to avoid waiting for all other scripts and make that action (style add after click) immediately ? Tried with plain javascript but got same result.
You can use modern way to write click event outside the document ready you will be able to perform click outside document ready.
$(document).ready(function() {
console.log('F Loaded');
});
$(document).on('click', '#div_id', function(event){
jQuery('#desired_element').css('display','block');
console.log('Clicked')
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="div_id">Click me</div>
<div id="desired_element" style="display:none">TEST CONTENT</div>
<html>
<head><title>test</title></head>
<body>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="Clickme">Click me</div>
<div id="Contentsection" style="display:none">Test Content content....</div>
<script>
$('#Clickme').on('click', function(event){
$('#Contentsection').show();
console.log('Clicked')
});
</script>
</body>
</html>
ON the display page, I'm loading contents into a container div using ("#mydiv").load("myphpfile.php"); This works fine. My question is, how do I work with elements inside that loaded div?
Here is the code sample:
<div id="contents"></div>
<script type="text/javascript">
$("#contents").load("___server_side.php");
$("#message").click(function(){
console.log('clicked');
});
</script>
"#message" is an element in the loaded div. How do I access it and assign functions to it from the display page?
You can use your code as is, yet I would add a .ready().
<div id="contents"></div>
<script type="text/javascript">
$("#contents").load("___server_side.php");
$("#message").ready(function(){
$(this).click(function(){
console.log('clicked');
});
});
</script>
Another option is to add the event callback once loading is finished.
<div id="contents"></div>
<script type="text/javascript">
$("#contents").load("___server_side.php", function(){
$("#message", this).click(function(){
console.log('clicked');
});
});
</script>
Otherwise I would use the .on() option.
<script type="text/javascript">
$("#contents").on("click", "#message", function(){
console.log('clicked');
});
$("#contents").load("___server_side.php");
</script>
<div id="contents"></div>

Have an anchor tag, trying to click it from the javascript but not responding, while loading the page it should go to next.php without click anchor tag manually.how can I archive this?
<!DOCTYPE html>
<html>
<head>
<title></title>
<script src="jquery-2.0.3.js"></script>
<script type="text/javascript">
alert("hai");
$(document).ready(function() { $('#about').click(); });
</script>
</head>
<body>
<div>
click here
</div>
</body>
</html>
Use $('selector')[0], as $('selector') returns a jQuery object, so $('selector').click() will fire the click handler, while $('selector')[0].click() would fire the actual click.
$(document).ready(function () {
$('#about')[0].click(); //$('#about').get(0).click();
});
Demo
You can not use javascript to fire click event
It should use
<script type="text/javascript">
$(document).ready(function() {
document.location.href='/next.php'
});
</script>
Here is the code that can help you
$(document).ready(function() {
$(document).ready(function() {
$('a').trigger('click');
});
})
function abc() {
alert("");
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
click me not
If you want the recommended way then use this inside $(document).ready
window.location="where ever you want to go";
If you want the page to go to next.php without clicking then place the window.location directly into $(document).ready(function() { });
Click() function is used when you want to trigger click event. ie. when you want to trigger some action when anchor tag is clicked.
<script>
alert("hai");
$(document).ready(function() {
window.location = 'next.php'; //If you wish the page to automatically go to next page on page load.
$('#about').click( // If you wish to do something clicking anchor
function(){
alert("Hello");
});
});
</script>
$(document).ready(function() { $('#about').trigger('click'); });
Updated:
$(document).ready(function() { $('#about')[0].click(); });
<div id ="instant-view">
<textarea id="upload-data-text" placeholder="Copy & paste your data here"></textarea>
</div>
<script>
$("#instant-view").hide();
</script>
here the the id "#instant-view" not hiding, i am not getting whats going wrong.
i am using jquery though
Wrap your code inside document's ready event like,
$(document).ready(function(){
$("#instant-view").hide();
})
Working Fiddle
Add $(function () {});
<script>
$(function () {
$("#instant-view").hide();
});
</script>
You are missing $(document).ready(function(){});
Use,
$(document).ready(function(){
$("#instant-view").hide();
});
use the code inside document ready
$(document).ready(function(){
$("#instant-view").hide();
});
Try this
$(window).load(function() {
$("#instant-view").hide();
});
Firstly, make sure you've included jQuery or reference it properly, normally I'd use Google CDN:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
Secondly, if you put your code at the end of your page then it's fine, but if you place your jQuery code in the <head> section then you need to wrap it inside DOM ready handler $(function() {...}); to make sure all DOM elements have been loaded properly.
$(function() {
$("#instant-view").hide();
});
Your final code should look something like this:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<script>
$(function() {
$("#instant-view").hide();
});
</script>
I'm trying to figure out why my jQuery isn't working. I've got jQuery linked to, and then after that, I try to bind to the textarea content. I've used name=content and name=#content both.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script type="text/javascript">
$('input[name=content]').bind('keyup',function(){
$('#desctag').val($(this).length)
});
</script>
Why isn't it working?
Code is now:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$('input[name=#content]').bind('keyup',function(){
$('#desctag').val($(this).length)
})})
</script>
You need to put it in a document.ready function so it executes when the DOM is ready.
$(document).ready(function() {
$('input[name=content]').bind('keyup',function(){
$('#desctag').val($(this).length);
});
});
