JavaScript - Need Help Creating Dynamic, Animated Buttons
Hi, I searched the web for a button that can be animated, as well as dynamic. but I couldn't find one, so I decided to try my hand at creating one.
My method is similar to a post made by Bram2: http://codingforums.com/showthread.php?t=153326, however, I have found my code to be unreliable and it doesn't apply only to the area where the table is, instead of spreading across the screen. The reason for trying to create a button this way is because I'm lazy, I don't want to create a new button in a graphics editor, spending hours trying to make it uniform with the rest of the buttons on the page, every time I want a new button. Doing it this way will also enable to have buttons with mulitple lines of text. I am fairly new to javascript, so I am wondering if anyone can give me a hand making it more reliable or pointing me to a script that has already been created. I put the button Here instead of filling the post with code. Please look at it before telling me it can be done with the <button> tag, because I tried before posting here. thanks, grayatrox Edit:I have managed to get the code to do what I wanted it to do, and more efficently too. Old code is commented out in the orginal webpage. This is a working example on how to impliment the buttons. javascript: Code: /*
Notes:
- Each button MUST have a unique name.
- You may need to create a secondary function that the button can activate like I did with the go(url) function below.
- Email me (grayatrox) at 238atrox@gmail.com for bugs, or to suggest improvements.
- Yes I know tables within tables is bad, if you read through my code carefully you will see where I am talking about.

Similar TutorialsHey all! So there I was newly hired and tasked with pouring through someone else's code to see what could be modified and brought up to date. After successfully finding the errors and correcting them and fulfilling the tasks my new supervisor assigned me, he slaps me on the back and says, "Well done! Now make it dynamic!" By which he meant the chapter buttons I spent hours creating from the existing code. Here's what he wants: the old code has an array, we'll call it someArray, that is assigned its values by the instructional developer as html pages are added to the course. So for example the code might look like this, Code: var someArray = new Array(4);
someArray[0] = "video1/video1.html";
someArray[1] = "video2/video2.html";
someArray[2] = "video3/video3.html";
Now, each page has an associated chapter button. So video1/video1.html would have ch1Btn, video2/video2.html would have ch2Btn and so forth. Each button in turn calls a specific function which does only one thing - sets the currentPage variable to page associated with that button/array contents. For example, I have created the following functions to call each page: Code:
function doCh1(){currentPage = 0; goToPage();}
function doCh2(){currentPage = 1; goToPage();}
function doCh3(){currentPage = 2; goToPage();}
I should mention that all this is being done from within an html wrapper that calls each page into an iframe. The currentPage variable is assigned the url of one of the elements from the pageArray. My supervisor wants to be able to manually add pages to the pageArray and have the javascript code generate the associated buttons and function calls so when the learner clicks on one of the dynamically created buttons, s/he is taken to the correct page. Currently I'm using static images with the onclick calling the correct function to set my currentPage value and send the learner on his/her merry way. Is there a way to do all of this dynamically? If so, can you help me get my head around this by providing some examples? Sorry for the long post. Thank you, M Everything works but I'm afraid that it might be slow due to my heavy use of setAttribute for my dynamically created buttons. This is the only place I've needed it because I was able to use this bit of code Old Pedant came up with. Here's what I'm trying to improve upon Code: span.setAttribute("onMouseOver","ShowPage(type_num,\"all\",1);ShowPage(type_num,\"y"+z+"\",1);");
Quote: Originally Posted by Old Pedant Code: xxx.setAttribute("itemnum",itemnum);
xxx.onclick = function() { return showRapidText(this.getAttribute("itemnum")); };
I don't understand how to apply that ^ to this > Code: span.setAttribute("onMouseOver","ShowPage(type_num,\"all\",1);ShowPage(type_num,\"y"+z+"\",1);");
My working version is here ... and the next bit is what I've tried and had no success with. Code: for (z=1920; z<=2010;z++){
var li = document.getElementById("Dynamic_Year_Filter_Reference");
var span = document.createElement("SPAN");
var text = document.createTextNode(z);
span.id = "y"+z+"_mainmenuimg"
span.className = "mainmenuimgyear"
span.setAttribute("onMouseOver","ShowPage(type_num,\"all\",1);ShowPage(type_num,\"y"+z+"\",1);");
span.setAttribute("onMouseDown","l_num=\"y"+z+"\";pg_num=1;ShowPage(type_num,l_num,pg_num);");
span.setAttribute("onMouseOut","ShowPage(type_num,l_num,pg_num);");
li.appendChild(span).appendChild(text)
}
}
Code: span.setAttribute("type_num", type_num);
span.onmouseover = function() { ShowPage(this.getAttribute("type_num"),"all",1);ShowPage(this.getAttribute("type_num"),"y"+z+"",1); };
Hi, I have an HTML table dynamically populated with data from a coldfusion query and having radio buttons - see code following below. I need javascript to see the radio buttons and the user's selection - "approved"; "denied"; or, "N/A". If the user selects "approved" for multiple rows and then Submit the information will update the database table and remove those rows. However, if the user selects "approved" and "denied" then I need to update the "approved" rows and stop the update at the "denied" row and show a dialog box which informs the user that the "Reason for Denial" text box must be entered. Then the Submit button can be engaged and the "denied" selection processed. Only one "denied" at a time will be updated - but all "approved" entries can be denied similtaneously - unless a "denied" intervenes. I do have javascript code for the "denied" selection with empty "Reason for Denial" text box - see below: Code: <script type="text/javascript">
function rationale() {
var denInfo = document.getElementById("denialReason");
if(denInfo.value == ""){
alert("Please enter reason for denial in Rationale for Request Denial");
return false;
denInfo.focus();
}
}
</script>
The overall action seems like it would need some extensive javascript coding and I haven't a clue how to do it. Any help is GREATLY APPRECIATED. Code: <table border="1" cellspacing="1" cellpadding="2" style="position:relative; left:50px;" width="1000">

Thank you, John I am developing a site that adds multiple dynamic buttons. I would be ideal if the event these buttons trigger could pass a 'variable' (the passed variable is constant with respect to each button). My attempt... myButton.setAttribute("onClick", "myFunction(" + myVar +")"); ...doesn't seem to work. Can anyone help out? hi i am newbie to js please help me like a newbie thanks. i want to make a form. the form will have three text fields and with two buttons. what i want with this form is when the user enters the first three fields and if he wants to add more then he will click on add more button and on the same page three more fields will appear below the first three fields. the user will then enter these three fields then if he wants to add more then he will click on add more button. so three more fields will appear below the first six fields. user will enter these fields. he will be allowed to enter upto eight or less than eight times. once he finishes with this then he will click the second button to insert this data into db. Hello, I'm trying to create a webpage where users can click on a dynamically generated set of questions: <?php do { ?> <p><?php echo $row_rsQuestions['question_text']; ?><?php echo $row_rsQuestions['question_type']; ?></p> <?php } while ($row_rsQuestions = mysql_fetch_assoc($rsQuestions)); ?> and by clicking on a particular question, there will be an update for their particular listing of personal questions in a MySql database. I know how to create the database update part, but I think that I would need to javascript to: 1) tell my page that it's time to update (i.e. add a particular question as soon as they click it) 2) pass along the correct variable to the database update portion of the page. Any help on these two items would be appreciated. Thank you! My application reads an array of URLs in Javascript and displays them in a table. I need to create mouseover events for each of the links (just an alert message for now.) I have tried this a few ways, but for each one the mouseover event fires for each link before anything else is loaded on the page, and when the page is loaded, no link is displayed. Here are the two ways I've tried: Code:
var cell1 = document.createElement("TD");
cell1.innerHTML = '<A HREF= ' + url + 'onMouseOver="' + alert("my alert box"); + '"> my page </A>';
Code: cell1.innerHTML = '<A HREF= "' + url + '"> my page </A>';
cell1.onMouseOver = alert('alert');
I have also tried many variations of these including: Code: cell1.innerHTML = '<A HREF= "' + url + '"> my page </A>';
cell1.onMouseOver = function(){alert('alert');};
Code:
var cell1 = document.createElement("TD");
cell1.innerHTML = '<A HREF= " ' + url + ' " onMouseOver=" alert("my alert box"); "> my page </A>';
But they all yield the same result, so any help would be much appreciated! Hi! I installed the Animated Information Bar found on http://www.javascriptkit.com/script/.../infobar.shtml Now there is a option to display the bar once per session but this isn't working... Code: infobar.setfrequency('session') //Uncomment this line to set information bar to only display once per browser session!
Anyone has installed this bar and knows why this isn't working? I use IE8 greetings Jardin Holland Hello This is brilliant and good to work with, there is one issue i have if someone can help please.

I copied the div and now have 2 collapsible divs next to each other, which nearly do exactly what i need. I have lined up the 2 divs next to each other they both open, but the one on the left pushes the right one out to the right and i don't know how to do that. here is the code thanks the animatedcollapse.js is too long to put but can be found here http://www.dynamicdrive.com/dynamici...edcollapse.htm Code: <script type="text/javascript">

Hey guys, I'd like to think this is fairly simple but unfortunately my knowldege of jquery is limited to using prebuilt scripts and changing a few variables to get what i need. I created a drop down menu with a slide down/up animation for submenus, which worked out just as I wanted. I ran into troubles though when trying to add a nested menu to the drop down, but with a slide animation going from left to right. I'm sure my explanation isn't very clear, so please take a look http://www.palousehillscomputing.com...rop/index.html The nested submenu I am speaking of should only open when hovering occurs on the 'Item 01' link, but as you can see it also opens when hovering over the buyers link. Secondly, my attempt to slide from left to right on this ul is not working. It seems to be sliding down even though this was not defined in the code. I've tried playing around with it for a while now and can't seem to figure this out so I'd appreciate if someone pointed me in the right direction. Thanks Hi I am trying to include an animated banner on my website but it wont work is there anyone out there who can look at my code and tell me where I am going wrong? Code:

I think the problem is that I have 2 onload functions in the body tag *<body onload="showCookies(); startBanner();">* does anyone know how I can fix this? Also when I put the Javascript into external files they won't work! but when I included the show cookies file in the html it works does anyone know where I am going wrong? Hi there, I just recently took over a site that has some java code on it I'm unfamiliar with. If you go to smalltowngossipmusic.com, you'll see what this code does. Go to the pages "Sounds" or "Travel", and once your mouse leaves the main image at the top of the page, you should see those pages shrink. This is some code that was implemented on the site (which is wordpress) in the header.php template. Here is the code: Code: <script type="text/javascript">
/* <![CDATA[ */
var $ = jQuery.noConflict();
$(document).ready(function () {
headerImage();
});
var speed = 500;
var origMT = 0, origHeight = '120px';
function expandHeader(obj) {
$('.headerImage').animate({height: '436px'},speed);
$('.headerImage img').animate({'margin-top': '-2px'},speed);
}
function shrinkHeader(obj) {
$('.headerImage').stop().animate({'height': origHeight},speed);
$('.headerImage img').stop().animate({'margin-top': origMT},speed);
}
function headerImage() {
origMT = $('.headerImage img').css('margin-top');
origHeight = $('.headerImage').css('height');
$('.headerImage img').css('margin-top','0');
$('.headerImage').css('height','436px');
setTimeout(shrinkHeader,speed*2);
$('.headerImage').hover(expandHeader, shrinkHeader);
}

If you look at the page source for each page, you'll see that there is nothing out of whack (at least, not that I can find). However, for some reason, this shrinking script only works on the two pages I mentioned - on every other page, it either doesn't work at all, or it only works about half-way. I have made sure the page.php and header.php templates both have accurate picture information in them, and can not find anything wrong anywhere. Is there any advice anyone here can give me on how to fix this? I've been doing html and css for awhile, but am relatively new to javascript and php, so am a bit out of my element on this. I'm willing to post any more code, snippets, whatever needed, just let me know what you need if you think you can help. Thanks, Brandon Hello, i wanna make animated news bar like the one in the top of site alibaba.com, so how can i do that, anybody have any kind of tutorial for any thing like this please ? thanks I have an animated gif of a door opening on my site. The animated gif is triggered onclick. (It's triggered only when the user clicks on a certain part of the door, hence the image map). This is the current code: <img src="img/door_admin_static.gif" width="229" height=401" alt="admindoor" usemap="#admin" name="animate"> <map name="admin"> <area shape ="rect" coords ="65,165,236,501" onClick="document.images.animate.src='img/door_admin.gif'; return true" href ="admin.html" rel="nofollow" target="_self" alt="admin" /> </map> What is supposed to happen is that after the user clicks, the animation of the door opening runs, and then the user is taken to the page linked to that door (in this case, admin.html). As it is now, the user is taken immediately to the admin.html page, so they never get to see the animation run. I need some kind of code that makes it so that the user is taken to the admin.html only after the animation is complete. Any help would be greatly appreciated!! I am trying to do what I thought was a very simple animated menu. I have a heading at the top of a website - which is just a png. I have a menu that is simply a div with a few options on it arranged horizontally. There's no submenus, it's just a very simple horizontal list. All I am trying to do is to hide the menu and then when you mouseover the heading, it will drop down. When you mouseout, it will move back up. It would be great if it faded in as it moved down too. Am sure it's probably very simple, but I've looked all over Google and I can't find a simple solution that doesn't do X, Y and Z that I don't want or need in this project. I just need a very simple script that I stand half a hope of understanding! The 2 sites below are animated scrolling pages which I know how to do, What I am looking for is how do they make the effect like the pages are sliding independent "like an overlaid effect" of each other If anyone can show me how they get that effect or if there are any demo or examples to help me figure it out http://www.sketchtravel.com/ http://www.foofighters.com/us/discography thanks for your help -rob Does anyone have an explanation for why animated .gifs might not animate in FF, Chrome, etc.? Only IE does it right for me. I suspect it might have something to do with tables squeezing the graphic (if the .gif is inside a table with a 100% width cell... but even giving the cell with the .gif a width doesn't seem to help.) Is it true? I realise tables are not best used for this purpose, but did this also happen in the good old tables days? Hi there. I'm relatively new to coding in javascript, so I'm hoping that some kind souls could help me out! I'm trying to make an animated image height changer (example: changing an image's height from 50px to 500px). I'm working on a new web site using HTML5 and want to add some Flash-like animation to my page using javascript and <canvas>. The animation would only need to "play" one time once the web page has loaded. No looping is required and no user interaction (ie mouseovers, etc) is needed. Any help would be greatly appreciated. If anyone knows of similar examples online please send me a link. If you're interested in helping, please let me know if more information is needed. Thanks. I'm using some free javascript for my website and I'm trying to edit it slightly to behave the way I want on my site. Right now it works fine apart from one thing... It remembers the last active div that was open... then when you visit the site again or refresh the page... that div stays open and doesn't close when toggling the other animated divs like it is supposed to. How would I remove the last active div function or get it to close again when toggling other animated divs.. Thanks so much if you can help Here is the site: www.gjoob.terryarchonship.com here is where the last active div java is Code: showhide:function(divid, action){
var $divref=this.divholders[divid].$divref //reference collapsible DIV
if (this.divholders[divid] && $divref.length==1){ //if DIV exists
var targetgroup=this.divgroups[$divref.attr('groupname')] //find out which group DIV belongs to (if any)
if ($divref.attr('groupname') && targetgroup.count>1 && (action=="show" || action=="toggle" && $divref.css('display')=='none')){ //If current DIV belongs to a group
if (targetgroup.lastactivedivid && targetgroup.lastactivedivid!=divid) //if last active DIV is set
this.slideengine(targetgroup.lastactivedivid, 'hide') //hide last active DIV within group first
