JavaScript - How To Make Rollover Effect Ready To Go Onload?
Hi,
I used this link fader script on my website: http://www.javascriptkit.com/script/...inkfader.shtml. The browser activates this script when I move my mouse over the link - that's understood. But unlikely the browser needs 1 or 2 seconds to activated it (to read it) so the whole effect is delayed - it happens every first time I use the links after loading the page. Question: is there a way to make the browser "read and remember" the script before I use the link so no delays appear? Any onLoad formula? Thanks Similar TutorialsHi Guys, I hope this is a good place for me to post a question. I saw some responses referring to this and I hope as a newcomer my question is not booed! :) I am attempting to compound a rollover effect I have currently working at this page. The 4 numbered buttons make the larger image next to it change upon on roll over. I would like the buttons themselves also to have a rollover state. In my code below, I simply added a space in my JS script after the portion of the script that I know is working ends and added the newer code referring to 71, or rollimg71 (an arbitrary number). The area that says //button rollover effect is the code I added that does not break the site but does not work correctly. My JS <code> // JavaScript Document //gallery rollover effect if (document.images) { image0 = new Image; image1 = new Image; image2 = new Image; image3 = new Image; image0.src = 'ectonymimages/newsletter1.jpg'; image1.src = 'ectonymimages/newsletter2.jpg'; image2.src = 'ectonymimages/newsletter3.jpg'; image3.src = 'ectonymimages/newsletter4.jpg'; } else { image0 = ''; image1 = ''; image2 = ''; image3 = ''; document.rollimg = ''; } //button rollover effect if (document.images) { image71a = new Image; image71b = new Image; image71a.src = 'ectonymimages/newsletter1_link.gif'; image71b.src = 'ectonymimages/newsletter1_linkselected.gif'; } else { image71a = ''; image71b = ''; document.rollimg71 = ''; } </code> My HTML <code> <div style="float:left; padding:10px 0 0 25px;"> <span onmouseover="document.rollimg.src=image0.src;" onmouseover="document.rollimg71.src=image71b.src;" onmouseout="document.rollimg71.src=image71a.src;"><img src="ectonymimages/newsletter1_link.gif" alt="Newsletter 1 Button" name="rollimg71"/></span> <br /><br /><br /> <span onmouseover="document.rollimg.src=image1.src;"><img src="ectonymimages/newsletter2_link.gif" alt="Newsletter 2 Button" /></span> <br /><br /><br /> <span onmouseover="document.rollimg.src=image2.src;"><img src="ectonymimages/newsletter3_link.gif" alt="Newsletter 3 Button" /></span> <br /><br /><br /> <span onmouseover="document.rollimg.src=image3.src;"><img src="ectonymimages/newsletter4_link.gif" alt="Newsletter 4 Button" /></span> </div> <div style="float:right; padding-right:50px;"> <img src="ectonymimages/newsletter1.jpg" align="Newsletter Example" name="rollimg"/> </div> </code> Right now, my HTML only attempts to affect the first button, but I hope to have it affecting all 4 buttons. (Presumably if I keep this same format, they would be rollimg72, rollimg73, and rollimg74 added somewhere in the JS) Further, I'll also compound an onclick function, for both the buttons and the larger images, that will open a pop up HTML window. So, my priorities are that I'd love for the buttons themselves to have a rollover effect and then also an onclick function that opens a link in a new window in addition to the rollover effect currently being used. *If I mouse over a numbered button, that numbered button changes. *If I mouse over a numbered button, depending on the numbered button doing the affecting, a larger image is displayed next to it that changes on rollover. (This step already works correctly.) *If I click on a numbered button, 1 of 4 links would open. If I click on the larger image that changes, 1 of 4 links would open.

Any help is much appreciated! Gentlepeople, I ask your assistance. -Marcus I'm trying to add an image rollover effect, but when I put it into play, the first image slowly fades into the second image and stays at the second image before I even hover my mouse over it. I've tried multiple scripts and it still seems to be happening www.alternativeland.com Does anyone have an idea as to why? Hi, I found the following code on a web site. It displays text as if it were being typed but it only does it once. I have been trying to use various functions to make the effect continuous, i.e. make the header appear as typing text, clear the text, again make the header appear as typing text, clear the text, and so on. I wish this to continue for as long as the web page is open. But I just can't get it to work. I wonder if anyone has any suggestions? I would be very grateful for all help.

Window.onload How can i get to know when document is ready to use using pure javascript? Hi there. I want to slide in (jquery) a link in the bottom right when the page loads that offers the user to be pushed back to the top of the page. So far all is well. I have it appearing at width 1024 or bigger. With a media query set in order for it not to appear for smaller devices: #totop { position: fixed; bottom: 0; right: 10px; background: #FFF; color: #000; padding: 10px; -moz-border-radius: 5px 5px 0 0; border-radius: 5px 5px 0 0; display:block; -moz-box-shadow: 10px 10px 5px #000; -webkit-box-shadow: 10px 10px 5px #000; box-shadow: 10px 10px 5px #000; } @media screen and (max-width: 1023px) { #totop { display: none; /* Remove to top button */ } Now I understand I want an if statement checking whether the css is to display block or none. Or if this doesn't work have an if statement checking the screen width itself rather than media queries. So far I have this: $(document).ready(function() { if( $('#totop').is(':visible') ) { ("#totop").slideDown("slow"); } else { ("#totop").hide(); } }); Please help! Hi Guys, I've written the below code which submits to a servlet, does a bit of processing and returns a JSON object. I'm reaching the servlet, but I never reach the alert("ready()") in the JavaScript. It looks as though the readyState never actually reaches state 4. Any ideas what is wrong ?? Thanks Code: function fetchhits() {
var httpRequest = null;
var url = "http://localhost:8080/Json/FetchTopHit?amount=1";
try {
httpRequest = new XMLHttpRequest(); /* e.g. Firefox */
} catch(e) {
try {
httpRequest = new ActiveXObject("Msxml2.XMLHTTP"); /* some versions IE */
} catch (e) {
try {
httpRequest = new ActiveXObject("Microsoft.XMLHTTP"); /* some versions IE */
} catch (E) {
httpRequest = false;
}
}
}
httpRequest.open("GET", url, true);
httpRequest.onreadystatechange = handler;
httpRequest.send(null);
}
function handler() {
alert("hander() start");
if (httpRequest.readyState == 4) {
alert("ready...");
if (httpRequest.status == 200) {
processJson (httpRequest.responseText);
}
}
}
function processJson(jsonObjectString) {
alert ("Process the Json Object");
}
I'm trying to diagnose the javascript part of an ajax script: Code: <form>
<ul id='May120128AM' name='apt_time' value='May120128AM'>
<input type="hidden" id='May120128AMhidden' name="user_id" value='May120128AM'>
</form>
<script type="text/javascript">
<!--
var request;
request = new XMLHttpRequest();
function checkData()
{
alert(request.readyState);
}
var apt_time = encodeURIComponent(document.getElementById(May120128AM').value);
var userid = encodeURIComponent(document.getElementById(May120128AMhidden').value);
var parameters = "apt_time"+apt_time //+"&"+"user_id"+userid;
request.open("POST", "/cgi-bin/my_script.php", true);
request.onreadystatechange = checkData;
request.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
request.send(parameters);
//-->
</script>
The checkData script puts each readyState in an alert box, so I know the javascript is firing. If I change the red line of code to this, the alert boxes no longer pop up, so I assume the javascript is not firing: Code: var parameters = "apt_time"+apt_time+"&"+"user_id"+userid; I thought name/value pairs were written like this: Code: name1=value1&name2=value2 I though that was exactly what the red line of code was doing. Does anyone know why it isn't firing? UPDATE: This works: Code: var parameters = "apt_time=+apt_time+&user_id=+userid"; I don't know why the above works and the other doesn't. They both look like they do the same thing - this: Code: apt_time=value1&user_id=value2 All, I currently have this code to make a post to my database: Code: var $dataString = 'name='+ $name + '&black_white=' + $black_white + '&color=' + $color + '&color=' + $other + '&other_text=' + $text;
$.post("save_edits.php", {image_save_string: $dataString}, function(result) {
$("#multiple_images").hide();
$("#result_success").html("<font color='red'>We've successfully saved your photo edits!</font><br><br>");
$("#image_divs").html(result);
});
Within the result I'm actually recreating the form for them to use if they want. I have a decent amount of jQuery that got initialized when the original page was loaded. Once I get my new form it doesn't work because it wasn't originally included in the page initialization. Is there a way just to call the document.ready function again to have it reinitialize my form elements again? Thanks in advance. I have a website which includes stories with multiple chapters. These chapters have a set of clickable arrows at top and bottom to take you forwards and back through the chapters, including a "last chapter" arrow. When a story is in progress, the URL of the last chapter changes with each chapter added. Rather than having to go back into every previous chapter and change the URL of the last chapter by hand, I set them up so that the "last chapter" arrow is actually in an inline frame. That way, I only have to change the URL once, in the file go_end.htm which is the source for the frame. So both the picture of the arrow and its hyperlink are being accessed from outside. My web pages are also set up to run on all major browsers and to detect the window width and resize all the artwork to fit, regardless of the browser and whether or not it accepts percentage sizes. Go_end.htm is no exception - it contains Javascript code which resizes the arrow so it is the same size as the ones which are actually in the parent page, outside the frame. This setup works perfectly in IE and Netscape, but Google Chrome either fails to display the arrow or makes it huge so it doesn't fit the frame. This seems to be because their superfast new Javascript editor is *too* fast. If I bung an alert command into go_end.htm, asking it to say the value of picWidth (the variable which sets the width of the arrow) as it loadfs, what happens is this. Google Chrome displays an alert saying that picWidth is zero, then loads the first instance of the inline frame with no got-to-end arrow. Then it displays an alert giving a proper value for picWidth and loads the second inline frame with the arrow correctly displayed and sized. If I take out the alerts, it doesn't load the arrow in *either* frame. It's obvious that inserting the alert command somehow forces it to recognise the value of the variable which it then retains for long enough to load the arrow on the second pass. Any ideas for some command other than alert which would trick it into not loading the image until it's recognised the variable? If I put a time delay on loading the frame I can't see that that would help - the problem is that from the point at which it starts actually loading the frame it needs to wait for the variable to be set. Hello all. I have fairly simple questions regarding modifying this script: http://papermashup.com/create-a-dynamic-form-preview/ to dynamically show different parts of a form on another part of the page. I am looking to use it on most parts of my form and would like a little clarification. First is the use of $(document).ready(function() or $(function(). It works using either, my question is which is preferred? As I understand it using $(document).ready(function() starts the DOM immediately on page load and is useful if you need something right away. I am also using this script: http://www.dynamicdrive.com/dynamici...formwizard.htm for the form. Since the preview script is being used with the form to wizard, I don't really need it until the rest of the form loads. Another question would be, is there a cleaner way to go about using the preview script on say 10 different form inputs independently? For example in a single function rather than 10 different function/updates? I have an example of what I am trying he http://jsfiddle.net/anhyG/1/ Thank you in advance for any help! Hi all I would like the img src to be populated after page load I'm not sure this is doing what I would like it to do. I have done this. (tag shortened for post) Code: <img src="" id="testImg2" onload="(this.src='images/USA.jpg')"/> Is this populating the img src after page load or when the img tag is loaded? LT I have this code: Code: <script type="text/javascript" src="http://s7.addthis.com/js/250/addthis_widget.js#username=xa-4c7b22470e521876"></script> I want this JavaScript code above to be executed when all My page finished loading (maybe by using JavaScript onload) So how can I do that? Am I saying the onload event wrong or something? PHP Code: <input type="button" value="Mouse" onload="popup_show('popup', 'popup_drag', 'popup_exit', 'mouse', -10, -10);" /> Other events like onmouseover and onClick work Hi, I'm looking to create a box that shows to IE6 users or lower, to tell them that my site does not render properly in the IE6 browser and that they should therefore upgrade to a newer version or alternative browser. Basically I would put whatever the code to show the box into these tags: Code: <!--[if lte IE 6]> INSERT HERE <![endif]--> to enable it to only appear to IE6 or below users. Preferably when this box appeared, it would be nice if it could fade the page behind it. Does anyone have a script for this or know of a tutorial I could use? The box would also need buttons at the bottom that said "Ok, upgrade me" (this would load another window with links to alternative browsers) or "No thanks" (or "Close") Thanks in advance. Hi there, I'm trying to port a pretty old javascript to a brand new Joomla website. I didn't create the original site that the javascript comes from, and haven't been able to locate it in my Google searches either. I'm assuming it's quite old. That being said, it seems to *want* to load up correctly. Since this is in an individual Joomla article, I didn't want to set the template to always try and load this script from <body>, so I'd found what I thought might be a workaround by calling it from another javascript within the article. It *looks* like it starts to want to call the required images, but then they disappear. I am not a javascript programmer in any way. I really don't do more than copy & paste various scripts of that nature. So I'm a little flummoxed here. Any help you can afford will be appreciated. Here is the development page: Mixes Thanks in advance. ~Laura hi guys, how can i get this code to load on body onload? without fading in and out? Code: <html>
<head>
<!-- For ease i'm just using a JQuery version hosted by JQuery- you can download any version and link to it locally -->
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script>
$(document).ready(function() {
$("#responsecontainer").load("response.php");
var refreshId = setInterval(function() {
$("#responsecontainer").load('response.php?randval='+ Math.random());
}, 9000);
$.ajaxSetup({ cache: false });
});
