ERROR - Uncaught ReferenceError: myclick is not defined
http://jsfiddle.net/hiteshbhilai2010/33wLs160/6/
I have checked with already existing question here but my problem is happening when I am trying it in jsfiddle
Can some one please help me ....thanks
You need to select No library (pure JS) and No wrap - in head. Then it will work as a simple HTML with javascript page.
This will be inserted in a <script> element in the <head>:
function myclick(){
alert("myclick")
}
See demo
As others said, for first case you have to set No wrap - in <head> or No wrap - in <body> as javascript panel settings (the blue link at js panel top-right).
For the second (your Edit) question, your code inside a function and the js will run it (within a new context), but it will do nothing as you just define a function and ignore it without any call or assignment.
if you call alert(myclick) you will see all the code is executed and its defined at that point. see this fiddle
$(document).ready(function() {
//alert("ready is executed");
function myclick(){
alert("myclick is called")
window.location.reload(true);
}
alert(myclick); //this will show the myclick is a defined function!
//document.getElementsByTagName("input")[0].onclick = myclick;
})
if you call this:
document.getElementsByTagName("input")[0].onclick = myclick;
in that $(document).ready({...}) scope, it will be assigned to the button and works as you wish.
<input value="press" id='a' type="button">
document.getElementById('a').onclick = function() { alert(1); }
http://jsfiddle.net/gs6rehnx/12/
This one is working. Just remove it from document ready event. Also semicolons are optional in javascript but i advice to use them.
function myclick() {
alert("myclick");
window.location.reload(true);
}
<input value="press" type="button" onclick="myclick();">
<script>
alert("home");
</script>
Here is the fiddle.
Select "No wrap - bottom of " in "Load Type" of the scripting panel.
This is the solution for Jsfiddle (till 17 december 2019).

Can't add a comment yet, nothing's wrong with the code, but to make it work in jsfiddle change onLoad to noWrap
Description of what each of the settings does: http://doc.jsfiddle.net/basic/introduction.html#frameworks-and-extensions
Basically you need it to be in a simple <script> tag, not in the onLoad event
Fiddle with the code you provided: http://jsfiddle.net/Sam88/YEPm3/12/
Since you mentioned jQuery in your tags, I thought I'd give a jQuery solution: Fiddle
Html:
<input type="button" id="saveFavPunch" name="saveFavPunch" value="save" />
Javascript:
$("#saveFavPunch").on("click", function () {
alert('hello2');
});
:)
Edit
Javascript Not Running On JSFiddle is a possible duplicate of your question. I am quoting the selected answer:
The functions you define are defined in an onload function, so whereas before they were referenceable, because they are defined in that function they can only be referenced from within that function. You reference them as globals in your HTML. You have three options
a) ( easiest, quickest, not ideal ) - change function blah(){} to window.blah = function(){}; making the functions global.
b) ( ideal way ) - use unobtrusive Javascript to attach behaviour to DOM elements from within the JS solely, meaning separate HTML from JS.
c) Make the jsfiddle not wrap the stuff onload. Change onLoad to no wrap ( body or head ).
So instead of you'd do var e = document.getElementById('foo'); e.onclick = lol; in the JS only.
I recommend b as it encourages best practices.
Just one change — JSFiddle setting from "onLoad" to "No wrap - in " and it works:
http://jsfiddle.net/3f7PT/
The problem with the onLoad option is that this is what it outputs in the results:
//<![CDATA[
window.onload=function(){
function saveFavPunch(){
alert('hello2');
}
}//]]>
So your function gets unintentionally wrapped in another function which stops it being found from that onclick call.
Hope this helps.
The following entire script works properly in Chrome for me.
<html>
<head>
<script>
function saveFavPunch(){
alert('hello2');
}
</script>
</head>
<body>
<input type="button" id="saveFavPunch" name="saveFavPunch" value="save" onClick="saveFavPunch()" >
</body>
This works
document.getElementById("saveFavPunch").addEventListener("click", saveFavPunch);
function saveFavPunch(){
alert('hello2');
}
http://jsfiddle.net/6sg9R/
Ye JSFiddle is very finicky about Alerts. It works no problem as Spassvogel shows but your way should work as well from file as opposed to on JSfiddle.
Even those you having this type of problem then use div tag
<div id="saveFavPunch" style="height:30px; widht:100px; display:block;" onClick="saveFavPunch()">Save</div>
I think Using this code Your problem will solve.
This question already has answers here:
JavaScript not running on jsfiddle.net
(4 answers)
Closed 8 years ago.
this is probably stupidly easy but I'm very new to JavaScript and it's driving me nuts.
My question, why doesn't this work:
http://jsfiddle.net/Ye9tG/
<input type="button" id="butt" value="Button" onclick="getThought();"/>
It works fine if I add the onclick directly into the JavaScript:
document.getElementById("butt").onclick = getThought;
Thanks in advance.
Your getThoughts function isn't defined, because your JavaScript is set to execute onLoad. See the dropdown menu in the upper left of jsFiddle. Select "No wrap - in <head>" to resolve the issue: http://jsfiddle.net/Ye9tG/1/
Also, always take a look at your browser's console to check for errors. In this case, you'll see a Uncaught ReferenceError: getThought is not defined error when clicking the button.
In the top left corner of jsfiddle you'll see that your fiddle is set to run your js code "onLoad". What that really means is that jsfiddle creates this for you:
<script type='text/javascript'>//<![CDATA[
window.onload=function(){
// YOUR CODE HERE
}//]]>
</script>
As a result, your function is only accessible within that onload function. Change the value to "no wrap head" and you'll see that it works.
Your other option would be to make your function explicitly global:
window.getThought = function(){
// ...

I am trying to understand the difference between JQuery and JavaScript.
And apologies if this is a silly question.
This is my attempt at JQuery. On pressing the button the text in <p> should change as requested. I cannot get this to work.
http://jsfiddle.net/QaHda/7/
this is my JavaScript attempt. I cannot get this to work either
http://jsfiddle.net/aLhb8/1/
Can someone please help me with
my jQuery above to get it working.
my jscript above to get it working.
I was trying to get to a point where I could write my JQuery in such a way that it could be written in javascript. Can anyone help me do this?
Thanks
EDIT
Thanks for all the answers/corrections: what I was looking for part 3 was this enter link description here which basically does part 1 using javaScript,I think. In future I should be careful,using left hand pane, to include Jquery library and to make sure jsript is wrapped in head/body
jQuery
You need to include jQuery library to your page by selecting a jQuery version in the first dropdown in the left panel
Demo: Fiddle
JS Sample
The problem is since your function is defined within the onload callback, it was not available in the global scope causing an error saying
Uncaught ReferenceError: myFunction is not defined
The solution is to add the script to the body elements, instead of inside the onload callback by selecting No Wrap - in <body> in the second dropdown in the left panel
function myFunction()
{
alert("Hello World!");
}
Demo: Fiddle
jQuery is library of javascript function and you need to add jquery file in html file that y jquery function was not working and for javacript function you need to change the setting in jfiddele left to no-wrap in head
http://jsfiddle.net/aLhb8/1/
http://jsfiddle.net/hushme/QaHda/10/
here is code
$("button").on("click", function () {
$("p").text("this text will now appear!!")
});
If you have internet connection, This should work
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
$(document).ready(function() {
$('button').click(function() {
alert("This is a simple alert message");
});
});
But if don't then just download the jquery framework and include into your page
Hope it helps and anyway jquery is a framework of javascript, so they are both or they are the same. Don't confuse yourself.
Here is a JavaScript version - http://jsfiddle.net/aLhb8/4/
JavaScript
var myButton = document.getElementById('myButton');
myButton.addEventListener('click', function(){
alert(myButton.textContent);
});
Check this link out if you want to start learning more about JavaScript - http://javascriptissexy.com/how-to-learn-javascript-properly/
For the pure JS code, on the top left panel, select 'No wrap - in body'. This will make your code run without a problem.
In the jQuery code, make sure you've selected the jQuery library, as opposed to pure JS. You hadn't selected this before, so your code was invalid.
A simple JavaScript onclick event is not working but I don't understand why, here is the code:
<button onclick="removeLol()">remove style</button>
function removeLol() {
alert("hello");
}
and here is a simple example: http://jsfiddle.net/YNQg6/1/
That's only because of the way how jsfiddle inserts the javascript.
Jsfiddle wraps your code into a function which limits the scope and protects the global namespace:
window.onload=function(){
function removeLol() {
alert("hello");
element.className = element.className.replace(" lol ", "");
}
}
If you tell jsfiddle to inject the code into the document body it works:
http://jsfiddle.net/YNQg6/13/
Or you could turn your "local" function in a global one:
window.removeLol = removeLol;
The code works just fine (just tried it on my server). Check your console for other errors that may be causing the script to not run
I have the following javascript -
function onLoad() {
if (!(document.applets && document.VLVChart && document.VLVChart.isActive())) {
setTimeout('onLoad()', 200);
return;
}
objChart = document.VLVChart;
PollEvent();
}
function fan() {
objChart.reorganize();
}
And then when the HTML page is loaded -
<body onLoad="onLoad()">
and have a button within the HTML that execute the fan() function -
<input type='button' value='Fan' onClick='fan();'>
Is it possible for me to activate the fan() function within the onload event so that a user does ont have to click the button?
EDIT
After trying the provided answers, on debugging the code breaks on the line -
objChart.reorganize();
Within the fan() function with the error -
SCRIPT5007: Unable to get value of the property 'reorganize': object is null or undefined
This is odd as when I manually click the button on the page, the function works fine.
Solution
After much head scratching I have realised that I was trying to load the fan() function before the page (and more specifically the objChart) had fully loaded. Hence why adding the function in the onLoad event was not working. I added a setTimeout -
function Fan()
{
setTimeout(function(){objChart.reorganize();},3000);
}
<body onload='onLoad(); fan();'>...
However inline JS is best avoided and you would do well to begin looking into centralised event management. There are various advantages to this.
An answer I wrote yesterday to another question outlines why this is. Something like jQuery makes this trivial if it's new for you.
$(function() {
$('body').on('load', function() {
onLoad();
fan();
});
});
Reading your question I assume you didn't even have tried. Just call that function from within your onLoad()-function:
function onLoad()
{
fan();
/* … */
}
Yes.
You can use <body onload='onLoad(); fan();'> as Utkanos suggests.
If you use jQuery, you can also stick a script in the head containing:
$(function(){
...
});
The jQuery function actually fires earlier, as is explained here.
