This example works, but if i create local file like this:
<script src="jquery-big.js"></script>
<div id="test">
<div id="hello">click</div>
<div id="no-hello">click</div>
</div>
<script>
$('#test').click(function() {
if ($('#hello').is(':hover')) {
$('#hello').html($('#hello').html()+' strange ');
}
});
</script>
(removed all utf-8 bug-symbols from jsfiddle) - nothing works, and no errors in console. checked in Google Chrome 19.0.1084.46.
try like this~
<!DOCTYPE HTML>
<html lang="en-US">
<head>
<meta charset="UTF-8">
<title>question</title>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>

$(document).ready(function() {
$('#test').click(function() {
if ($('#hello').is(':hover')) {
$('#hello').html($('#hello').html()+' strange ');
}
});
});
</script>

<!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");
}
});
I am making a form validation and I set the property of other checkboxes disable if the owner checkbox is not checked but it is not working.
Here's my html cod:
<!DOCTYPE html>
<html>
<head>
<title>jQuery</title>
<script src="script.js"></script>
<script src="min.js"></script>
</head>
<body>
Owner:<input type="checkbox" id="owner">
<hr>
<div id="check">
bicycle:<input type="checkbox" id="bicycle"><br>
bike:<input type="checkbox" id="bike"><br>
car:<input type="checkbox" id="car">
</div>
<script>
</script>
</body>
</html>
and in it min.js is jQuery installation file and ,
here is script.js :
$(document).ready(function(){
var $checkbox = $("#check").find("input[type=checkbox]");
$checkbox.prop('disabled', true);
$("#owner").click(function(){
var $ownercheck = $(this);
if ($ownercheck.prop('checked') === true) {
$checkbox.prop('disabled', false);
}
else
{
$checkbox.prop('disabled', true);
}
});
});
You have to put min.js above the script.js,
and your html code will look like this :
<!DOCTYPE html>
<html>
<head>
<title>jQuery</title>
<script src="min.js"></script>
<script src="script.js"></script>
</head>
<body>
Owner:<input type="checkbox" id="owner">
<hr>
<div id="check">
bicycle:<input type="checkbox" id="bicycle"><br>
bike:<input type="checkbox" id="bike"><br>
car:<input type="checkbox" id="car">
</div>
</body>
</html>
You must always load the library first. For issue to be fixed, script.js must go after min.js. Your code is working perfectly fine: http://jsfiddle.net/zb3m3/1/
<script src="min.js"></script>
<script src="script.js"></script>
having an issue with some JS where the cookie is setting as soon as the page is loading, when it should only be setting when I've click to close the box.
Any help would be appreciated. Code below:
<!doctype html>
<html lang="en">
<head>
<title></title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
<script type="text/javascript" src="http://resources.site.co.nz/scripts/jquerycookie.js"></script>
<script type="text/javascript">
$(function() {
$('a.close').click(function() {
$(this).parent().fadeOut(1500);
$.cookie('hidden', 'true', { expires: null});
alert($.cookie('hidden'));
return false;
});
if($.cookie('hidden','true')){
$('#errororganinfoinchide-this').hide();
}
});
</script>
</head>
<body>
<div id='boxes'>
<aside class='warning' id='errororganinfoinchide-this'>
<a href='#errororganinfoinchide-this' class='close'><img src='http://resources.site.co.nz/backgrounds/close.png' /></a>
<img src='http://resources.site.co.nz/backgrounds/icon_warning.png' class='messageimg' />
<h4>Warning - Organisation Info</h4>
<p>Sorry, there was an error opening the "Organisation Info" Box. Please try again later.</p>
</aside>
</div>
</body>
Doesn't the line "if($.cookie('hidden','true')){" set the cookie instead of reading it?
It should probably be something like this instead...
if($.cookie('hidden') == 'true'){
<html>
<head>
<script>
function view_more(pg_no){
alert(pg_no);
}
</script>
</head>
<body>
<span onClick="view_more('1')"></span>
</body>
</html>
Here, I can't understand why it say always
[ReferenceError: view_more is not defined]
I got the same problem today.
My situation was like this:
.html file:
<head>
<script type="text/javascript" src="js/jquery-1.9.1.js"></script>
<script type="text/javascript" src="js/functions.js"></script>
</head>
<body>
<div class="lc-form-holder">
<form action="#" method="post">
[...]
<span onclick="myFunction();">NEXT</span>
</form>
</div>
</body>
and .js file:
$(document).ready(function() {
function myFunction() {
console.log('click click');
}
});
When I clicked on <span> I got an error Uncaught ReferenceError: myFuncion is not defined.
But when I do this in .js file (no document.ready):
function myFunction() {
console.log('click click');
}
Everything work just fine.
I don't know is this helpful but I wanna share it if someone check this question in future.
Try this first
<body>
<span onClick="alert('1');"></span>
if the above code works then there must exists others javascript which are actually got error prior to execute your code.
<span onClick="view_more('1')">Test</span>
Add text and then click on text
Working at my end
This is my code --
<html>
<head>
<script>
function view_more(pg_no){
alert(pg_no);
}
</script>
</head>
<body>
<span onClick="view_more('1')">gfgf</span>
</body>
</html>
EDIT
try using this code --
<html>
<head>
<script type="text/javascript">
function view_more(pg_no)
{
alert(pg_no);
}
</script>
</head>
<body>
<span onClick="javascript:view_more('1');">gfgf</span>
</body>
</html>
First off here is the code!
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<link href="content/wmd.css" rel="stylesheet" type="text/css" />
<title>some title </title>
</head>
<body>
<div class="main">
<form>
<h2>Only teaxt area</h2>
<div id="wmd-editor-uno" class="wmd-panel">
<div id="wmd-button-bar-uno" class='wmd-button-bar'></div>
<textarea name='id-uno' id='id-uno'></textarea>
</div>
</form>
</div>
<script type='text/javascript' src="Scripts/mootools-yui-compressed.js"></script>
<script type='text/javascript' src="Scripts/moowmd.js"></script>
<script type="text/javascript">
var MyConfig = [
{
input: 'id-uno',
postfix: '-uno'
}];
window.addEvent('domready', function() {
window.MyMooWMD = new mooWMD.WMD(window.MyConfig);
window.MyMooWMD.start();
});
</script>
</body>
</html>
Bam!
My problem is this, it doesn't work like the example at mooWMD tutorial all I get is an empty text area with the wmd.css style applied to it. I cant figure out what I could be doing wrong. All the file locations are correct but i get 'mooWMD' is undefined. I am at a loss any and all suggestions are appreciated.
The problem (for later generations) is IE does not accepts the following syntax:
{
att1: 'value',
att2: 'value'
}
Where other browsers do.
I changed it to
{
'att1': 'value',
'att2': 'value'
}
And it is fine now.
(using the mailing list would have gotten my attention earlier)
The code in the local javascript tag executes as soon as the tag is processed. This may happen before moowmd.js has completed loading.
Wrap the code in a function:
<script type="text/javascript">
function loaded() {
var MyConfig = [
{
input: 'id-uno',
postfix: '-uno'
}];
window.addEvent('domready', function() {
window.MyMooWMD = new mooWMD.WMD(window.MyConfig);
window.MyMooWMD.start();
});}
</script>
Then add an onload handler to your body tag:
<body onload="loaded();">
The onload handler will not fire until all the javascript, images, css, etc have loaded.
<head>
<title>some title </title>
<link rel="stylesheet" type="text/css" href="Content/wmd.css" />
<script type="text/javascript" src="Scripts/showdown.js"></script>
</head>
<body>
<div class="main">
<div id="wmd-editor" class="wmd-panel">
<div id="wmd-button-bar">
</div>
<textarea id="wmd-input"></textarea>
</div>
<div id="wmd-preview" class="wmd-panel">
</div>
<div id="wmd-output" class="wmd-panel">
</div>
</div>
<script type="text/javascript" src="Scripts/wmd.js"></script>
</body>
The root of the problem ended up being the moowmd editor just didn't work consistently in IE. The reason I was tiring to go with the moowmd was I liked how he handled setting up multiple editors. I ended up just switching to stackoverflow's branch of wmd it is working well so far.
