<option value="fiat">Mercedes</option>

</select>
</form>

The best I could do so far is replace onload with onMouseOver but then it does not allow you to type the letter of a name for quick searching if you have a very long list. Any advice?
THanks.
Write your code into $(document).ready(); function.
include jquery-1.9.0 framework.
Try below code.
<script>
$(document).ready(function(){
alert("open the dropdownbox automatically onload");
optionsSelect.focus();
// Other statements
});
</script>
// The rest of your code.

I've tried multiple variations of importing jQuery, but nothing is working. When I run it, everything in the body shows up, but the jQuery function doesn't work.
Here is my current code:
<!DOCTYPE html>
<html>
<head>
<script type='text/javascript' src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script type='text/javascript'>
$(window).load(function(){
$('select').on('change',function(){
var value=$(this).val();
var output='';
for(var i=1;i<=value;i++)
{
output+='<div>Your Text</div>';
}
$('#test').empty().append(output);
});
});
</script>
</head>
<body>
<select>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="10">10</option>
</select>
<span id="test">
</span>
</body>
</html>
What can I do to fix it?
Here are the errors I'm getting in my console:
The resource from
“https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.mi%C3%A2%E2%82%AC%C5%92%C3%A2%E2%82%AC%E2%80%B9n.js”

ReferenceError: $ is not defined[Learn More]
The character encoding of the HTML document was not declared. The
document will render with garbled text in some browser configurations
if the document contains characters from outside the US-ASCII range.
The character encoding of the page must be declared in the document or
in the transfer protocol.
Do below steps:-
Copy the jquery library code (https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js) code and save it with the same name in your current working directory (jquery.min.js):-
Now use this code:-
<!DOCTYPE html>
<html>
<head>
<meta content="text/html;charset=utf-8" http-equiv="Content-Type">
<meta content="utf-8" http-equiv="encoding"><!-- this is for removing character encoding error-->
<script type='text/javascript' src="jquery.min.js"></script><!-- see the change here -->
</head>
<body>
<select>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="10">10</option>
</select>
<span id="test">
</span>
</body>
</html>
<script type = "text/javascript">
$(document).ready(function(){
$('select').on('change',function(){
var value=$(this).val();
var output='';
for(var i=1;i<=value;i++)
{
output+='<div>Your Text</div>';
}
$('#test').html(output); //html will do everything(removing and then adding)
});
});
</script>
Note:- You can once try like this:-
<script type='text/javascript' src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
here is my html code.....
<!DOCTYPE html>
<html>
<title>Plot</title>
<head>
<script type="text/javascript" src="d3.min.js"></script>
<script>
function refilter()
{
var ch = document.getElementById('Choice').value;
//do something
}
</script>
</head>
<body>
<form action="save.php" name="myform" method="POST">
Select any station:<select id="Choice" name="choice">
<option value="None">Select</option>
<option value="option1">DELHI</option>
<option value="option2">MUMBAI</option>
</select>
<input type="button" onclick="refilter()" value="Submit!">
</form>
</body>
</html>
I wish to do two things:
1.save the "choice" entered by user, since I have to do further task using it and
2.call the "refilter" function.
As of now, I tried using php and store the "choice" in a text file but for that i need to change "input type=submit" and if I do so,
1.The function is not called.
2.the save.php file opens up, which i dont want. I wish to stay on the html page only.
I am a beginner to javascript and html and knew a little php, so tried my hand at that.
Is there anyway I can do both the tasks together?
You can do following with your code:
<!DOCTYPE html>
<html>
<title>Plot</title>
<head>
<script type="text/javascript" src="d3.min.js"></script>
<script>
<script>
window.onload = function() {
document.getElementById('test').onclick = function(event) {
document.getElementById('myform').submit();
// Do somthing
}
}
</script>
</script>
</head>
<body>
<form action="save.php" name="myform" id="myform">
Select any station:<select id="Choice" name="choice">
<option value="None">Select</option>
<option value="option1">DELHI</option>
<option value="option2">MUMBAI</option>
</select>
<input type="button" value="Submit!" id="test">
</form>
</body>
</html>
or you can follow: http://www.formget.com/form-submission-using-ajax-php-and-javascript/
Thanks.
The problem is that you want to have both the default behavior as well as your custom behavior.
Here's a simple solution you can try.
<form action="save.php" name="myform" method="POST" id="myform">
<input type="button" id="submit-btn" value="Submit" />
In javascript,
window.onload = function() {
document.getElementById('submit-btn').onclick = function(event) {
event.preventDefault();
refilter();
document.getElementById('myform').submit();
}
}
This will redirect the page to save.php anyway. If you don't want that, you can send a POST request via AJAX. Please find more about AJAX and post if you still face problems
I am looking for help in putting a cookie into this script so the browser remembers the background image selected when the browser is closed or changed page. Any help would be much appreciated!
function changeTheme()
{
var e = document.getElementById("themes");
var theme = e.options[e.selectedIndex].value;
console.log(theme);
document.getElementById("shelf").style.backgroundImage = "url("+theme+")";
}
<body id="shelf">
<select id="themes" onChange="changeTheme()" name="ChangeBG">
<option value="images/background1.jpg" selected="selected">Default</option>
<option value="images/background2.jpg">Heart</option>
<option value="images/background3.jpg">Earthly</option>
<option value="images/background4.jpg">Sunflowers</option>
<option value="images/background5.jpg">Mountin</option>
</select>
It looks like the only piece you are missing is the setting and getting of the cookie. Here is a post about setting and getting cookies using both jquery and javascript.
This is jquery but it gets the job done.
<html>
<head>
<script type="text/javascript" src="https://code.jquery.com/jquery-2.1.1.min.js"></script>
<!--download jquery.cookie from here http://plugins.jquery.com/cookie -->
<script type="text/javascript" src="images/jquery.cookie.js"></script>
<script type="text/javascript">
$(document).ready(function(){
var theme = $.cookie("backgroundImage");
if (theme){document.getElementById("shelf").style.backgroundImage = "url("+theme+")";}
$("#themes").change(function() {
theme = $(this).val();
$.cookie("backgroundImage", theme);
document.getElementById("shelf").style.backgroundImage = "url("+theme+")";
});
});
</script>
</head>
<body id="shelf">
<!--<select id="themes" onChange="changeTheme()" name="ChangeBG">-->
<select id="themes" name="ChangeBG">
<option value="images/background1.jpg" selected="selected">Default</option>
<option value="images/background2.jpg">Heart</option>
<option value="images/background3.jpg">Earthly</option>
<option value="images/background4.jpg">Sunflowers</option>
<option value="images/background5.jpg">Mountin</option>
</select>
</body>

I'm playing around with jQuery, and am having some trouble alerting a message on change of my select drop down element:
html:
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="script.js"></script>
</head>
<body>
<div>
<select id="fruits">
<option selected>Choose a fruit</option>
<option name="orange">Orange</option>
<option name="mango">Mango</option>
</select>
</div>
</body>
</html>
my js:
$('#fruits').on('change', function() {
alert('Hello!');
});
When I run this in Chrome, I don't get any warnings in my console, and changing the select option does nothing. Any idea what I'm doing wrong?
Put your code in document ready:
$(function () {
$('#fruits').on('change', function() {
alert('Hello!');
});
});
jsFiddle Demo.
try below code:
1.you must call js function or you can write code in ready function
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="script.js"></script>
<script>
$(document).ready(function(){
$('#fruits').on('change', function() {
alert('Hello!');
});
});
</script>
</head>
<body>
<div>
<select id="fruits">
<option selected>Choose a fruit</option>
<option name="orange">Orange</option>
<option name="mango">Mango</option>
</select>
</div>
</body>
</html>
you can try this too:
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="script.js"></script>
</head>
<body>
<div>
<select id="fruits">
<option selected>Choose a fruit</option>
<option name="orange">Orange</option>
<option name="mango">Mango</option>
</select>
</div>
<script>
$('#fruits').on('change', function() {
alert('Hello!');
});
</script>
</body>
</html>
I seem to get this null or not an object error over and over when I try to code in javascript. This is an simple example where I'm just trying to make a window pop up that displays the name of the option. How can I avoid getting this error when I'm coding?
The code returns this error in Internet Explorer:
Error: 'document.forms.0.questions' is null or not an object
<!DOCTYPE html>
<!-- HTML5 style -->
<head>
<title>Challenge Question</title>
<script type="text/javascript">
/* <![CDATA[ */
window.alert(document.forms[0].questions.pet.name);
/* ]]> */
</script>
</head>
<body>
<form action="get" >
<select name="questions">
<option value="pet" name="pet">What is your pet's name?</option>
</select>
</form>
</body>
</html>
The element must be added to the DOM first, then you can access it. Now you're trying to access an element that does not yet exist :
<!DOCTYPE html>
<html>
<head>
<title>Challenge Question</title>
</head>
<body>
<form action="get">
<select name="questions">
<!-- Element is added here -->
<option value="pet" name="pet">What is your pet's name?</option>
</select>
</form>
<script type="text/javascript">
/* and can be accessed here, after it's added */
console.log(document.forms[0].questions.options['pet']);
</script>
</body>
</html>
FIDDLE
I have tested the code. It works fine.
<script type="text/javascript">
function func1()
{
var index = document.getElementById("pet").selectedIndex;
var value = document.getElementById("pet").options[index].text;
alert(value);
}
<form action="get">
<select name="questions" id="pet" onchange="if (this.selectedIndex) func1();">
<!-- Element is added here -->
<option value="pet" name="pet" >What is your pet's name?</option>
<option value="pet" name="pet" >What is your pet's 1?</option>
</select>
</form>
