I am trying to figure out how to make this work. Please let me know if there is something I can change to make this code work without changing it completely.
<select name="fontPick">
<option value="0">Font</option>
<option value="1">Calibri</option>
<option value="2">Candara</option>
<option value="3">Tahoma</option>
</select>
<script type="text/javascript">
document.querySelector('[name="fontPick"]').addEventListener('change', function () {
var fonts = this.options[this.selectedIndex].textContent;
document.body.style.fontFamily = fonts;
});
</script>
<script type="text/javascript> you forgot the closing " make it
<script type="text/javascript">

I am trying to replicate this simple example but for the life of me cannot get it to work. The first picture displays, but it doesn't ever change. Forgive me if this is basic, I am pretty new with javascript.
<html>
<head>
<script src="/js/jquery-1.11.2.js"></script>
<script type="text/javascript">
var pictureList = [
"http://lorempixel.com/400/200/sports/1",
"http://lorempixel.com/400/200/sports/2",
"http://lorempixel.com/400/200/sports/3",
"http://lorempixel.com/400/200/sports/4",
"http://lorempixel.com/400/200/sports/5", ];
$('#picDD').change(function () {
var val = parseInt($('#picDD').val());
$('img').attr("src",pictureList[val]);
});
</script>
</head>
<body>
<img src="http://lorempixel.com/400/200/sports/1" />
<select id="picDD">
<option value="1" selected>Picute 1</option>
<option value="2">Picute 2</option>
<option value="3">Picute 3</option>
<option value="4">Picute 4</option>
<option value="5">Picute 5</option>
</select>
</body>
</html>
You need to place your code in :
// A $( document ).ready() block.
$( document ).ready(function() {
// Your code here.
});
Else your code wont work. In jsfiddle you can see on the left the javascript is loaded onDomready
$( document ).ready(function() {
$('#picDD').change(function () {
var val = parseInt($('#picDD').val());
$('img').attr("src",pictureList[val]);
});
});
In the jsFiddle, you don't have to specify the document ready function as it is done dynamically. Try this, it should work for you.
i have this simple html code
<html>
<body>
<select name="country" id="country">
<option value="1">Falkland Islands (Malvinas)</option>
<option value="2">canada</option>
<option value="3">Finland</option>
<option value="4">France</option>
<option value="5">United Kingdom</option>
<option selected="selected" value="12">United States</option>
</select>
</body>
</html>
if this dropdown menu is in the bottom of a webpage, and whenever the user selects one of the options on the menu, the user automatically go to the top of the webpage without reloading, i know it's simple but i could't do it, hope you help me guys, thanks.
In the head of your file, place this little snippet:
<script type="text/javascript">
window.onload = function(){
document.getElementById("country").onchange = function(){
window.scrollTo(0, 0);
};
};
</script>
There's no need to load jQuery for a simple action such as this; it's pointless to include such a large file for something Vanilla JavaScript can handle with ease.
This should take care of it for you... Add this to your <head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script type="text/javascript">
$(function() {
$("select#country").change(function() {
$("html, body").animate({ scrollTop: 0 }, "slow");
return false;
});
});
</script>
in my script, I have a select-field:
<select name="src[jumpMenu]" id="jumpMenu" onchange="ChangeImage(this.value,'preview');">
<option value="A">AStyle</option>
<option value="B">BStyle</option>
<option value="C">CStyle</option>
</select>
and I got this Javascript below:
<script language="Javascript" type="text/javascript">
<!--
function ChangeImage(newimage,imageid) {
if(document.getElementById(imageid).src != newimage)
document.getElementById(imageid).src = newimage;
}
// -->
</script>
and here is my problem:
I can't change the values because of the dependence for the other files (which I won't change).
Do you know any solution how to switch "A" to "img/src/A_top.png" for example and get it working with this script?
Thanks.
document.getElementById(imageid).src = "img/src/"+newimage+"_top.png";
Re-Edited:
I went over to W3schools and played around in there javascript editor window to see what was going on. Here is a shorter script.
<html>
<body>
<script type="text/javascript">
var eType = document.getElementById("Type")
</script>
<select class="field select addr" id="Type">
<option value="Type:L" selected="selected">Location</option>
<option value="Type:C">Corporate</option>
<option value="Type:R">Remittama</option>
<option value="Type:M">Mailing</option>
</select>
<script type="text/javascript">
document.write(eType);
</script>
</body>
</html>
I did what ThiefMaster suggested on how to get the element by not using the .text or .value but as you can see if you run this code I still get a null at this step of the process. From what I can see and many suggestions I am doing this correctly. I know I must be missing something. Can anyone see it?
You're trying to get the element before you've actually put it on the page. Fix the order, and don't use document.write.
<html>
<body>
<select class="field select addr" id="Type">
<option value="Type:L" selected="selected">Location</option>
<option value="Type:C">Corporate</option>
<option value="Type:R">Remittama</option>
<option value="Type:M">Mailing</option>
</select>
<script type="text/javascript">
var eType = document.getElementById("Type")
document.body.appendChild(document.createTextNode(eType));
</script>
</body>
</html>
Your second code block is almost correct; you need to use the select element itself instead of its (non-existent) value:
var elem = document.getElementById("Type");
var type = elem.options[elem.selectedIndex].value;
Demo: http://jsfiddle.net/ThiefMaster/nw3nN/
If you had jQuery available you could drastically reduce the amount of code necessary:
var type = $('#Type').val();
Could someone please tell me how to get this code working on a webpage? Particularly what should go in the header?

Sorry if this is a basic question...steep learning curve!
Thanks
Your code is using the jQuery JavaScript library ... so your head will need to contain :
<script type="text/javascript" src="<jquery url>"></script>
Replace the <jquery url> with a valid url to the jQuery library. I suggest you use the Google CDN for the url or alternatively download a copy and store it on your server -> http://docs.jquery.com/Downloading_jQuery#Download_jQuery
Then to ensure your code runs once the DOM is ready wrap all of your JavaScript within the following :
$(document).ready(function() {
// your code here
});
Docs for ready() here
If your going to be using jQuery more I suggest you start reading here http://docs.jquery.com/How_jQuery_Works and if you going to learn JavaScript, you can't go wrong with reading this too -> https://developer.mozilla.org/en/JavaScript/Guide
Copy the code below, save it with a .html extension (e.g. test.html) and then double click to open.
<html>
<head>
<title>Page Title here</title>
</head>
<body>
<select id="t_dermal_name">
<option value="t_default_dermal">-- Choose --</option>
<option value="1" rel="30">Between Eyebrows</option>
<option value="7" rel="30">Individual Line Softening</option>
<option value="2" rel="30">Lip Contouring</option>
</select>
<select id="t_wrinkle_name">
<option value="t_default_wrinkle">-- Choose --</option>
<option value="1" rel="30">Between Eyebrows</option>
<option value="7" rel="30">Individual Line Softening</option>
<option value="2" rel="30">Lip Contouring</option>
</select>
<span id="output"></span>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js"></script><!--You can use a local version of jquery-->
<script type="text/javascript">
$(document).ready(function(){
function onSelectChange(){
var total = 0,
dermal = $("#t_dermal_name").find('option:selected'),
wrinkle = $("#t_wrinkle_name").find('option:selected');
if(value = dermal.attr('rel')){
total += parseInt(value);
}
if(value = wrinkle.attr('rel')){
total += parseInt(value);
}
$("#output").html(total);
}
$("#t_dermal_name").change(onSelectChange);
$("#t_wrinkle_name").change(onSelectChange);
});
</script>
</body>
