JavaScript - Please Help - Need Prev And Next Btns Implemented In Existing Code
Hey,
I need help. I have my HTML/CSS/Javascript slideshow working fine, the images fades in and out nicely. Now I realized I'd like to implement next and prev buttons, but I don't know how to code this and what to refer to in the existing code. Please help? I have ten thumbnails total. Here's the Javascript: <script type="text/javascript"> slidePrefix = "slide-"; slideControlPrefix = "slide-control-"; slideHighlightClass = "highlight"; slidesContainerID = "slides"; slidesControlsID = "slides-controls"; slideDelay = 3000; slideAnimationInterval = 30; slideTransitionSteps = 10; function setUpSlideShow() { // collect the slides and the controls slidesCollection = document.getElementById(slidesContainerID).children; slidesControllersCollection = document.getElementById(slidesControlsID).children; totalSlides = slidesCollection.length; if (totalSlides < 10) return; //go through all slides for (var i=0; i < slidesCollection.length; i++) { // give IDs to slides and controls slidesCollection[i].id = slidePrefix+(i+1); slidesControllersCollection[i].id = slideControlPrefix+(i+1); // attach onclick handlers to controls, highlight the first control slidesControllersCollection[i].onclick = function(){clickSlide(this);}; //hide all slides except the first if (i > 0) slidesCollection[i].style.display = "none"; else slidesControllersCollection[i].className = slideHighlightClass; } // initialize vars slideTransStep= 0; transTimeout = 0; crtSlideIndex = 1; // show the next slide showSlide(2); } function showSlide(slideNo, immediate) { // don't do any action while a transition is in progress if (slideTransStep != 0 || slideNo == crtSlideIndex) return; clearTimeout(transTimeout); // get references to the current slide and to the one to be shown next nextSlideIndex = slideNo; crtSlide = document.getElementById(slidePrefix + crtSlideIndex); nextSlide = document.getElementById(slidePrefix + nextSlideIndex); slideTransStep = 0; // start the transition now upon request or after a delay (default) if (immediate == true) transSlide(); else transTimeout = setTimeout("transSlide()", slideDelay); } function clickSlide(control) { showSlide(Number(control.id.substr(control.id.lastIndexOf("-")+1)),true); } function transSlide() { // make sure the next slide is visible (albeit transparent) nextSlide.style.display = "block"; // calculate opacity var opacity = slideTransStep / slideTransitionSteps; // fade out the current slide crtSlide.style.opacity = "" + (1 - opacity); crtSlide.style.filter = "alpha(opacity=" + (100 - opacity*100) + ")"; // fade in the next slide nextSlide.style.opacity = "" + opacity; nextSlide.style.filter = "alpha(opacity=" + (opacity*100) + ")"; // if not completed, do this step again after a short delay if (++slideTransStep <= slideTransitionSteps) transTimeout = setTimeout("transSlide()", slideAnimationInterval); else { // complete crtSlide.style.display = "none"; transComplete(); } } function transComplete() { slideTransStep = 0; crtSlideIndex = nextSlideIndex; // for IE filters, removing filters reenables cleartype if (nextSlide.style.removeAttribute) nextSlide.style.removeAttribute("filter"); // show next slide showSlide((crtSlideIndex >= totalSlides) ? 1 : crtSlideIndex + 1); //unhighlight all controls for (var i=0; i < slidesControllersCollection.length; i++) slidesControllersCollection[i].className = ""; // highlight the control for the next slide document.getElementById("slide-control-" + crtSlideIndex).className = slideHighlightClass; } </script> And here's the HTML: <body onload="setUpSlideShow()"> <div id="slideshow"> <div id="slides"> <div class="slide"><img src="images/image1.jpg" width="1020" height="500"/>Slide content 1</div> <div class="slide"><img src="images/image2.jpg" width="1020" height="500"/>Slide content 2</div> <div class="slide"><img src="images/image3.jpg" width="1020" height="500"/>Slide content 3</div> <div class="slide"><img src="images/image4.jpg" width="1020" height="500"/>Slide content 4</div> <div class="slide"><img src="images/image5.jpg" width="1020" height="500"/>Slide content 5</div> <div class="slide"><img src="images/image6.jpg" width="1020" height="500"/>Slide content 6</div> <div class="slide"><img src="images/image7.jpg" width="1020" height="500"/>Slide content 7</div> <div class="slide"><img src="images/image8.jpg" width="1020" height="500"/>Slide content 8</div> <div class="slide"><img src="images/image9.jpg" width="1020" height="500"/>Slide content 9</div> <div class="slide"><img src="images/image10.jpg" width="1020" height="500"/>Slide content 10</div> </div> <div id="slides-controls"> <a href="#">1</a> <a href="#">2</a> <a href="#">3</a> <a href="#">4</a> <a href="#">5</a> <a href="#">6</a> <a href="#">7</a> <a href="#">8</a> <a href="#">9</a> <a href="#">10</a> </div> </div> Similar TutorialsI would like to know if anyone cane explain some javascript source code that i got from the chess.com website.

I have recently used this tutorial: http://net.tutsplus.com/tutorials/ph...-confirmation/ to develop a more complex sign up form for a competition for a client. Basically, the way the validation has been done is different to many other validation methods I've used before and don't understand how to implement it, for some additional requirements. This is an example of the PHP validation code that I have altered, to suit my form requirements: Code: //quick/simple validation
if(empty($code)){ $action['result'] = 'error'; array_push($text,'You forgot to enter your entry code'); }
if(empty($name)){ $action['result'] = 'error'; array_push($text,'You forgot to enter your name'); }
if(empty($email)){ $action['result'] = 'error'; array_push($text,'You forgot to enter your email address'); }
This code only validates that there is content in those fields. But, for example on the 'entry code' field, I would like to put a maximum character input there and restrict certain characters, as well as a standard 'email' validation, so that the form is sent through to the database correctly. If anyone knows how I can do this, with this sign-up form in particular, please assist me, as every other method I've tried to work with this form hasn't worked and caused the form to error. Thank you in advance. I followed a tutorial on Lynda for a simple HTML5 slideshow and altered it so that it doesn't auto play and has next and previous button controls. I can't quite figure out the previous button. Code: </script>

This doesn't quite work. If you click on the back button it goes forward one slide then back Then when you click the next button you have to click it several times before it will go forward again. Any help would be greatly appreciated Hi all ! I was searching for this problem over and over in here adn other websites but coudn't find any solution. Ok here is the problem: I made a video playlist in XML. Here is how it looks like: Code: <videotemplate> <videoblock> <video id="1"> <title>test1</title> <src>sd.webm</src> <img>diagnoza.jpg</img> </video> <video id="2"> <title>test2</title> <src>video.webm</src> <img>resident.jpg</img> </video> <video id="3"> <title>test3</title> <src>sd.webm</src> <img>resident.jpg</img> </video> </videoblock> <videoblock> <video id="4"> <title>test4</title> <src>video11.webm</src> <img>resident.jpg</img> </video> <video id="5"> <title>test5</title> <src>video4.webm</src> <img>resident.jpg</img> </video> <video id="6"> <title>test5</title> <src>video5.webm</src> <img>resident.jpg</img> </video> </videotemplate> Them I am using this javascript + XLST to play next file: Code: <script type="text/javascript">
function nextSrc<xsl:value-of select="@id" />() {
var myvideo = document.getElementsByTagName('video')[0];
myvideo.src="file://d:/cis/guide/<xsl:value-of select="videoblock/video/following::src" />";
myvideo.load();
}
</script>
When I use nextSrc function video flips to next xml record with <src> tag but it only does that once! How to make it flip to next video every time ?? Please help ! Hi I've got a javascript that searches for a Youtube video. This script gets called by a window.onload action. The function actually works just fine, but IE (not in FF) still throws me an "Not Implemented" error at my window.onload action. the code is this: Code: window.onload = GetYoutubeVideo('Alice Cooper Poison');
Find it he http://www.muzikum.eu/en/123-3496-44...son-lyric.html I can't seem to get rid of it. Can anyone explain me why it's triggered? Even as the code does get executed it's still annoying me. thanks in advance Walter I am in the process of learning 'JavaScript' and I am having a problem understanding how to delete cookies. I understand that to do delete a cookie you want to set the expiration attribute of the cookie to delete, to any date in the past. My confusion lies in the exact syntax of how to do this. In the example s I have seen in books and on the internet it appears that you must submit the "exact" name/value pair that you originally set the cookie with to delete it. For an example: var UserId = "MrJones", password = "secret"; var currentDate = new Date(); currentDate.setFullYear(currentDate.getFullYear()+1); document.cookie = encodeURI("userid=" + UserId " + "; " + "password=" + password + "; expires=" + currentDate.toUTCString()); What is the minimum syntax I would need to delete the cookie above? Also, I need clarification on the terminology. Is a single cookie a collection of name/value pairs(also known as crumbs) or is each name/value pair considered a cookie unto itself? Why does the ECMA board allow people on drugs to be part of settings standards for programming languages that will be used by the entire world? I've been reading a book on JavaScript and have had no problems understanding anything until reaching Chapter 9 and the subject of cookies. This syntax is crazy. And the way you add to a cookie by using just an assignment operator? How about a cookie.Add() and a cookie.Delete() method? Hi guys, I'm trying to make a "mini image slider" and I want to create a next and prev buttons to show hidden images. Ex: I have a list with images and when I click on the next button I want to show the next hidden image. I've tried to do it with jquery but I can't. Code: <ul> <li><img src="image" alt="" 1="">Image 1</li> <li><img src="image" alt="" 2="">Image 2</li> <li><img src="image" alt="" 3="">Image 3</li> <li><img src="image" alt="" 4="">Image 4</li> <li><img src="image" alt="" 5="">Image 5</li> </ul> Can some one help me to achieve that? I have inherited some Javascript code from a colleague that was laid off recently, and I know very little about Javascript. I'm hoping someone here can help me out. I'm getting a Javascript error in IE for "Not implemented". Here is the full error that I get: Line: 34 Char: 1 Error: Not implemented Code: 0 And here is the Javascript code that I'm working with. It is located in a separate .js file. I'm not sure why the person who wrote it didn't use semicolons - I thought these were necessary. Anyway, the Javascript: Code: // List all the image files below with the corresponding HTML code
var item=new Array()
item[0]="<p><a href='case_study.pdf' target='_blank'><img src='graphics/frame1.gif' border='0'></a></p><p class='homepage_quotes_para_pad'><b>“</b>It translates to a quick learning curve and fast product development.<b>”</b></p><p class='homepage_box_para_pad'><i>Developer</i><br>Foo Inc.</p>"

var current=0
var ns6=document.getElementById&&!document.all
function changeItem(){
if(document.layers){
document.layer1.document.write(item[current])
document.layer1.document.close()
}
if(ns6)document.getElementById("customer_logos").innerHTML=item[current]
{
if(document.all){
customer_logos.innerHTML=item[current]
}
}
// The number of images being rotated is list here
if (current==2) current=0
else current++
setTimeout("changeItem()",10000) // Set the time between rotations
}
window.onload=setTimeout("changeItem()",10000)
//-->
Now I've looked around the web, and it seems like the error is happening because of that last line (the "window.onload") -- IE doesn't like the way it's written, I guess. I've tried some different suggestions that I found, but they all seem to break the functionality that the Javascript is used for (rotating an image and quote). Any help you can give me is greatly appreciated. Thanks in advance. I have an iframe. I load a page within it. The page I load is a php page that I build with a table with the id of 'readmail_table'. My iframe is 'readmail_frame'. Someone clicks on a message title outside of the iframe and I load the contents of the message in the iframe from the database in my table. Sometimes this takes longer than others depending on how large the message is. What I am doing here is letting the contents load then calculating the width and height of the table and then increasing the iframe's size so there are no scrollbars. This works 98% of the time but I ran into an issue where the table does not exist yet in the iframe and the JS code errors out. So what I did then was add a local var, set it to false then had a while loop check for the table and once it finds it, set the var to false and run my code. Again, mixed results. Sometimes this works then others I get that the table id I am looking for is null but my if statement in the while loop is checking to see if != null line 159 is where it is breaking The error I am getting in firebug is Code: window.frames.readmail_frame.document is null Line 159 Code: 156 var temp = false;
157 while ( !temp )
158 {
159 if ( window.frames[ "readmail_frame" ].document.getElementById( 'readmail_table' ) != null )
160 {
161 //height of the table that holds the actual message
162 var tempheight = window.frames[ "readmail_frame" ].document.getElementById( 'readmail_table' ).clientHeight;
163 //height of the from, to, subject and date section
164 var tempheight2 = window.frames[ "readmail_frame" ].document.getElementById( 'readmail_heading' ).clientHeight;
165 var tempwidth = window.frames[ "readmail_frame" ].document.getElementById( 'readmail_table' ).clientWidth;
166 document.getElementById( 'readmail_frame' ).style.width = tempwidth + 'px';
167 //add up the table for the message, table for from, to, date and icon for print and some extra to ensure enough room
168 document.getElementById( 'readmail_frame' ).style.height = ( tempheight + tempheight2 + 130 ) + 'px';
169 temp = true;
170 }
171 }
I have also tried Code: if ( window.frames[ "readmail_frame" ].document.getElementById( 'readmail_table' ) ) and Code: if ( window.frames[ "readmail_frame" ].document ) Like I said, most of the time this works exactly how I need it. I just need a fool proof way to determine that this table is in fact on the page. I am not sure why it works sometimes and not others since I am looping until it is there Thank you for any help with this. I know for sure that lastRowTD_s[i] does not have "textarea" element ! The whole page is html valid. Code: else if (lastRowTD_s[i].getElementsByTagName('textarea'))
{
alert(lastRowTD_s[i].id);
//checked, it is the row that does not have "textarea" element.
alert(lastRowTD_s[i].getElementsByTagName('textarea'));
// gives me [Object HTML collection] !?
alert(lastRowTD_s[i].getElementsByTagName('textarea')[0]);
//gives me "undefined", heh where has it gone since previous line ?
}
Hey CF, I've been meaning to learn the answer to this question for a long time, I guess now is the time and place to hopefully have it answered. I'm wanting to know if there is a technique one can use to have Ajax request live data from a database as it happens but I want it to do this with out having to request a bunch of other information with it. Imagine you come to a webpage and there is the latest 10 comments on a video. Let's say that I want new comments to arrive as they happen (say every 5 seconds we will do an Ajax hit on the server). Let's say for sake of argument there is 2 new comments. Is there a way to make Ajax only request and display the latest 2 comments with out having to refresh the 10 latest as well? If this sounds confusing, try imagine the 10 comments as an array. I just want to pop one off the end and push a new one onto the front. Any tips in the right direction would be great to hear. Hi guys! As title says I need to create variable named with value of other variable! So is that possible? What exactly I need is something like this: Code: for(var i=0; i<11; i++){
var Img[i] = ""
}
Im trying to add to each element within an array. In this program I have an existing array which is called aScores. I have copied its contents into another array called aScores using slice. Now Im trying to add the value of variable called classCurve to each element of aCurve using a for loop (see under the Curve Scores functrion section). However, it does not seem to add the two together(e.g 78 + 5). Any advice would be very helpful. Here is my code: Code: <?xml version="1.0" encoding="UTF-8"?>

I'm not really much of a javascript programmer, but I occasionally use javascript that I've found here and there. But I'm unable to find anything that helps me in what I'm trying to do now. I regularly use a snippet of code that pops up a small window to display an image or a very small html file. Using the window.open() function, I'm able to disable scrolling, resizing, etc., and size it to my needs. I'll have a window.close link somewhere on the page. But in my current project, my customer's page has several links related to other companies. When you click on the link, an that company's ad pops up in a small window. At this point, the viewer can simply close the window, or they should be able to click on the ad and be taken to that company's website. I'm able to have it close the window and open that new url in the parent browser window, but my website customer doesn't want their site to go away. They want the new company's website in a new window. Or I can simply NOT close the popup window, but now the new company's website is in a relatively small browser window, unable to scroll, resize, etc. Is there a way for me to somehow modify an existing window with an onclick directive - something similar to the window.open() function, OR open a new browser window with window.open() AND close the popup window? If I haven't made myself clear, let me know and I'll try to explain myself better. Thanks in advance for any help. I am working on a site which is pretty old school.. i have a vertical drop down menu using javascript which uses <img src tag>.. Check the tab fountains at http://www.texaslakesandponds.com/index_html.html (it has a vertex and kasco dropdown) I want to add a similar dropdown for Aerators with the same format and color. I dont know how to do that since it uses a <ul><li> format and the image is called in the css class. Can someone please help me with the code. Hi all and hope you can help. I have a form validication function that checks a variety of form inputs which appears to be working fine. Trouble is that if I deliberately throw it some non-valid entries it clears the form with the data I've already supplied. Can anyone suggest a method for preserving the input the user has already made so that this doesn't need to be re-input when the user has input invalid data? My thanks Rog Here's my validation code. which checks.. Whether a user has input their full name - entering full name is optional and if not true will negate subsequent checks, i.e. doesn't bother checking any other inputs. Whether a user has supplied both first and last names, fail message pops up if not. Whether a user has suppllied a full name but not an email or telephone number, fail message pops up if not. Whether a user has supplied a valid email address, fail message pops up if not. Whether a user has supplied a valid telephone number, fail message pops up if not. If we've passed all these tests, O.K. - submit. Code: function check_id(){
var status = false;
var emailRegEx = /^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/i;
var telRegEx = /^\s*\(?(020[7,8]{1}\)?[ ]?[1-9]{1}[0-9{2}[ ]?[0-9]{4})|(0[1-8]{1}[0-9]{3}\)?[ ]?[1-9]{1}[0-9]{2}[ ]?[0-9]{3})\s*$/;
// 1st test, are the name fields blank, this is valid if the user doesn't want to enter the draw?
if (document.feedback.first.value =="" && document.feedback.second.value =="") {
status=false;
confirm("You will not be entered in our free prize draw unless you supply your full name and email address or telephone number. Is that O.K?");
return status;
}
// 2nd test, has the user supplied both a first name and surname?
else if (document.feedback.first.value =="" || document.feedback.second.value =="") {
status=false;
alert("You need to supply your full name to enter the draw.");
}
// 3rd test, has the user supplied a full name but not supplied an email address or tel number, this isn't valid.
else if (document.feedback.email.value =="" && document.feedback.tel.value ==""){
status=false;
alert("You need to supply either a valid email address or telephone number to enter the draw.");
}
// 4th test, user has supplied an email address and / or an email address and tel, check each.
else if(document.feedback.email.value !=""){
// 4th test part 1, user has supplied an email address, check it is valid.
if (document.feedback.email.value.search(emailRegEx) == -1) {
alert("Please enter a valid email address.");
status=false;
}
else {
alert("Thank you. You will be entered into our free prize draw. Good luck!");
status = true;
}
return status;
}
// 4th test part 2, has the user supplied a tel number, this is a valid option, check it.
else if (document.feedback.tel.value !="" ) {
if (document.feedback.tel.value.search(telRegEx) == -1) {
alert("Please enter a valid telephone number.");
status=false;
}
else {
alert("Thank you. You will be entered into our free prize draw. Good luck!");
status = true;
}
return status;

If i have an existing HTML Select statement with options specified, and then based on an even, i want to rebuild that options list, how do I wipe the existing options parameters in order to add new ones? Is that even possible?

Can anyone advise a solution for this please? Thanks alot Joe Hi there, I'm looking for some help with modifying an existing function which controls the highlighted states of a multi level js accordion menu. I have had to use javascript due to certain css elements not working in safari browsers. My problem is due to the multi level aspect as when a sub link is clicked, the parent link above it then deselects. I need the parent link to stay active when its sub links are clicked and only deselects when a link outside of that list is clicked upon. I understand the theory of adding a conditional statement but simply don't know how to apply it correctly within the function...any help would be very much appreciated. Here is the existing function which tells a link to be active or selected: Code: var Lst;
function CngClass(obj){
if (Lst) Lst.className='.topnav';
obj.className='selected';
Lst=obj;
}
and here is the menu code: Code: <ul class="topnav"> <li><a href="#">Home</a></li> <li><a onclick="CngClass(this);" href="#">Top Link 2</a> <ul> <li><a onclick="CngClass(this);" href="#">Cookies</a></li> <li><a onclick="CngClass(this);" href="#">Events</a></li> <li><a onclick="CngClass(this);" href="#">Forms</a></li> <li><a onclick="CngClass(this);" href="#">Games</a></li> <li><a onclick="CngClass(this);" href="#">Images</a></li> <li><a onclick="CngClass(this);" href="#">Navigations</a> <ul> <li><a onclick="CngClass(this);" href="#">CSS</a></li> <li><a onclick="CngClass(this);" href="#">JavaScript</a></li> <li><a onclick="CngClass(this);" href="#">JQuery</a></li> </ul> </li> <li><a onclick="CngClass(this);" href="#">Tabs</a></li> </ul> </li> <li><a onclick="CngClass(this);" href="#">Tutorials</a> <ul> <li><a onclick="CngClass(this);" href="#">HTML</a></li> <li><a onclick="CngClass(this);" href="#">CSS</a></li> <li><a onclick="CngClass(this);" href="#">JavaScript</a></li> <li><a onclick="CngClass(this);" href="#">Java</a> <ul> <li><a onclick="CngClass(this);" href="#">JSP</a></li> <li><a onclick="CngClass(this);" href="#">JSF</a></li> <li><a onclick="CngClass(this);" href="#">JPA</a></li> <li><a onclick="CngClass(this);" href="#">Contact</a></li> </ul> </li> <li><a onclick="CngClass(this);" href="#">Tabs</a></li> </ul> </li> <li><a onclick="CngClass(this);" href="#">Contact</a></li> <li><a onclick="CngClass(this);" href="#">Upload script</a></li> </ul> Thanks for any help or advice. |
