JavaScript - Onclick Display Variable Content

I'm doing a school project and I am using JPlayer as a media player. The site is essentially a music jukebox with a search. I have the playlist set up in the jukebox with 5 songs from the start, but I need to make it so that when you do a search and click the plus sign button next to a song, it will change one of the songs in the playlist to that song.

I have the search and everything working but when I click the button it does not actually change the variable in the javascript. Any help or insight to this would be much appreciated.

Below is the javascript (with some PHP, but that shouldn't effect what I need).

Thanks in advance!!

Also, the code for the playlist is in the myPlayList array, which I'm referencing the title, artist, and filename with the javascript values. I'm trying to change them in the function loadSong(songID, artist, title). I get the alert popup that I have in there, but no values change as far as the songs.

So ill try best to describe what im doing,

I grab information from a database and it displays with its model number and a value. I use that value to put into a URL so it will go to the database and delete that values entry. It works excpet it ALWAYS grabs the last value(aka the last entry). So i need it to grab what ive selected rather than the last value.

Any help will be great!


Code:

<form name="addswitchtype" id="addswitchtype" action="<?php echo $this->url('system/switch_management/newtype'); ?>" method="POST">
<h4>Update Switch Model Information</h4>
<table>
        <select name"switchtypeid" id="switchtypeid">
                        <option value="">New</option>
                <?php foreach($this->switchtype as $switch_type): ?>
                        <option value"<?php echo $switch_type->switchtypeid; ?>"><?php echo $switch_type->switchmodel; ?></option>
                <?php endforeach; ?>
        </select>
 </table>

Hello, I am trying to access a dynamic asp variable with onclick either in a javascript function where I can use it globally or set another div id with this dynamic variable.

Any help is very much appreciated. Thank you!



<script>
function doSomething(article_id)
}
return article_id;

}
</script>

<a href="#test" onClick="doSomething("<%=rsHeadline("article_id")%>")">try here...</a>

<div id="test">
<%articleid = request.querystring("article_id") %>
<% Response.Write articleid %>
The article id is articleid</div>

I have a form, that when the user click Submit, I need a php variable to be echoed to the page.
This is for an upload page. So when they are waiting for the file to upload, it will say "Uploading..." until the upload is complete.

All I know so far is I need to create a javascript function and include it in the submit button. This is all I have so far in the submit button tag:
onClick="Transferring();"

Now I need to figure out the code to include in this function.

Any ideas?

from my spry sub.menu tab,
i'm trying to use "onclick" to post a new img in a specific div elsewhere on the page.

<li><a class="MenuBarItemSubmenu" href="#">CPQC</a>
<ul>
<li><a href="#" onclick="document.getElementById('cpqcRange').src='images/cpqc/cpqcHot.png';">Hot</a></li>
</ul>
</li>

<div id="cpqcRange">
<p>
<img src="cpqcLocation.png" alt="cpqcLocation" name="cpqcLocation" width="504" height="360" id="cpqcLocation" />
</p>
</div>

i think i'm close, but something is wrong.
can you just call up the div "cpqcRange" by name and slap a new img.src in there???????

cheers,
Paul

today's weather in Kalispell, MT, USA

it was about 18degF this morning

This is driving me crazy!

So I'm using a javascript file to switch out items when a thumbnail is clicked. This includes photo, title, description, price, size, quantity and add to cart button....

The original code on the html file works fine, but as soon as it is swapped by onclick, the 'add to cart' button does nothing!

Here is the code:

Code:

var addDisplay = document.getElementById('cart-add');
	addDisplay.innerHTML = "<a class='item_add' href='/' onclick='simpleCart.add(); return false;'><img src='images/shop/cart-add.jpg' width='118' height='26' border='0'></a>";

that is what shows in my javascript file...

here is what's on the html file:

Code:

<div id="cart-add"><a class='item_add' href='/' onclick='simpleCart.add(); return false;'><img src="images/shop/cart-add.jpg" width="118" height="26" border="0"></a>
                            </div>

and that adds the item to the cart just fine, but when a thumbnail is clicked on, activating the javascript file to switch out the item/elements, the 'add to cart' button no longer does anything... by the way, I am using simpleCart.js

PLEASE HELP, PLEASE!?

Please PM me if you need more info... or post here if you have a solution. Thanks!

Simply put, I need to take a variable (The number '20' in this case) that is displayed by an input box on my web page and plug it into a function so that whenever I click on a button, the number in the input box will decrease by 1.

Seems simple enough, though for hours I've been going at it with no luck. Skipping the rest of my code - I currently have:
Code:

 <head>
   <title> Online Slots </title>
   <script type="text/javascript" 
           src="http://dave-reed.com/book/random.js">
   </script>
   <script type="text/javascript">
     function DoSpin()


     {
       var count;
	   count = 20
	   document.getElementById("countBox") = count - 1;
  }

	

   </script>
 </head>

 <body>

   <div style="text-align:center"> 
     <input type="button" value="Click to Spin" onclick="DoSpin()" />
	 <br /><br />
	    Current Funds: 
     <input type="text" id="countBox" size="4" value="20" onfocus="blur();" />
   </div>

 </body>

The entire code is a slot machine project that's supposed to be extremely simple where you hit the button and it spins 3 wheels, 3 of the same image and you win. Every spin takes $1, every win gives $13.

The majority of the code is already working, however for some reason I appear to be failing badly at getting the read out to show a decrement of $1 every time you push the button.

I know this is a bit newbie of a question to be asking; but I've tried so many different ideas that I've found across w3schools, webdevelopersnotes, dave-reed, ect - and so far I haven't been able to get any of them to work correctly.

Any help would be great!

Below is the code that is using the name FFF in
various places. The effect of all this is that the onclick function is not executed.
I would expect a pop up alert when clicking the submit button.

This only happens if I rename either the form id or the js variable.
Can anyone explain what is going on here ?

Code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>Title</title>
    </head>
    <script type="text/javascript">
        function newobject(){
            this.exec=exec;
            function exec(){
                alert("exec");
            }
        }
         FFF  = new newobject();
    </script>
    <body>
        <form id=" FFF " name="somename" action="" method="GET">
            <input type="text" id="someid" name="somename" value="value">
            <input onclick=" FFF .exec()" type="submit" id="submitid" name="somesubmit"  value="xxx">
        </form>
    </body>
</html>

Well, I'm a beginner to coding, so I need some help.
I'm trying to create a short, html/javascript mario text game.
Now, in the beginning, he fights a goomba.
He has a health and energy number as variables:
Code:

<p><img src="http://img253.imageshack.us/img253/9202/mariodisplayidlefront.png" align="middle" hspace=20>
<font size=3 color="red">
Health:
<script language= "javascript">
var mariohealth = '20';
document.write(mariohealth);
</script>
</font>
<br><font size=3 color="green">
Energy:
<script language= "javascript">
var marioenergy = '20';
document.write(marioenergy);
</script>
</align>
</font>

And the goomba has health:
Code:

<p><br><img src="http://img23.imageshack.us/img23/9438/goombafrontdisplay.png" align="middle" hspace=20>
<font size=3 color="red">
Health:
<script language= "javascript">
var goombahealth = '10';
document.write(goombahealth);
</script>
</font>

And then, there will be different buttons for different attacks. However, the only one created is "Punch", with this code:
<FORM>
<INPUT type="button" value="Punch" name="Mario Punch" onClick="?">
</FORM>

What would I put in the onClick function to make it subtract 4 health from the goomba and 2 health from Mario

Hello all,

I'm trying to set up a web page to display a video when a user clicks on a link. So far, it works fine in IE and Chrome, but it won't work in Firefox. Any ideas?

I have a html page with a lot of thumbnails. The idea is that when the user clicks on an image the onClick event is to display another detailed form and deliver to that form the name of the image in a variable. In the detailed php-form there is a query to MySQL to retrieve a record. The record will be retrieved by a Query based on the name of the picture.
Apparently the PHP cannot do the job. I had an idea to make the thumbnail page as a form and to use use a hidden field with the thummnail name which should be carried on with the $_POST array through the submit button but i do not want to have a submit button. The more elegant way is just by clicking the picture the detailed page is opened and the variable is transferred
where my php code can make use of the variable for the query.
I have never used java before so you have to excuse for the lack of knowledge.
Can anyone gie me an idea how i should implemnt this
Best regards

Hey all, I'm using a fairly simple accordion script. When I went to take a gander at the page in IE I found that the onclick function of the script doesn't respond. It works in FF, Safari, Chrome and Compatibility Mode in IE 8

the error message IE gives me is
Quote:
Message: 'h' is null or not an object
Line: 13
Char: 77
Code: 0
URI: http://proposalfor.us/js/script.js
The problem line (as far as I can tell) is:
Code:

this.a[s]={}; this.a[s].h=h=T$$(e,v)[0]; this.a[s].c=c=T$$('div',v)[0]; h.onclick=new Function(this.n+'.pr(0,'+s+')');

Any help would be greatly appreciated!

Hi,
I have created three tabs to display different content in each.

Although I can click and go to the specific tab, but except the first 1 the other two tabs don't display any content or html that I have.

Can anyone find any problem in the code?

I have attached just the html. please excuse the structure of the code as it needs to be that way.

thanks
