JavaScript - Need Help Adding A "randomizer" To This Code.
Hi Everyone,
I'm using the code below to rotate between some testimonials for my website and I realized that it would be better to make the order random rather than always cycling the same each time to be sure the later ones get equal visibility on the home page. I found the code and tweaked it as I needed but I'm not familiar enough with java to know how to add a randomizing component. I'd appreciate any help offered since I hope it's straight forward enough for someone who knows the language well. Thanks a lot! [CODE] var quote=new Array(); quote[0]="An essential tool in preparation for any show. Valuable time is saved, refining vocals much earlier in the process."; quote[1]="Invaluable for learning vocal lines! A brilliantly simple and easy to use interface that saved me hours of time."; quote[2]="MixMyPart saved us almost a week of rehersal time. A brilliant invention. Singers come in less nervous and more focused."; <!-- quote[3]="An invaluble tool for learning vocal lines!

if( value.length<1 || value==field_values[$(this).attr('id')] || ( $(this).attr('id')=='cemail' && !emailPattern.test(value) ) ) {
$(this).addClass('error');
$(this).effect("shake", { times:3 }, 50);
error++;
} else {
$(this).addClass('valid');

I need to figure out the on page button code, what I need to add to the javascript file AND what I need to add in the CSS. (css is here) Thank you SO much to whoever can help. Can anyone please help integrating these two javascripts? http://milesich.com/ and http://javascript.internet.com/forms...-controls.html I want to allow visitors too choose as many dates as they want but when I try to integrate these two script timepicker stops working... Can anyone please help? Thanks in advance Hi, The following code adds an element to a page when a new address is inputted. Is there a way to remove all added elements with a Clear All button? I have a "Clear All" button with id="ClearAddresses" but I don't know how to remove all created elements - the code here only removes one at a time, since the element is created when the "Search" button is clicked.

I am trying to manipulate a an image gallery that functions well. Now, I have the ability to pull information from a user's preference pannel and need to place it in the an href="" // And other information in each of the "src" | "url" | "alt". Any ideas would be truly helpful. This is what I am working with at the moment and it doesn't work (obviously because it is adding code inside a span). Here is what I am starting from: [CODE] var title01Span = document.getElementById('title01Span'), //Finds the id that I want prefs = new gadgets.Prefs(), // Pulls from the user's preferences yourtitle01 = prefs.getString("title01"); // Pulls the correct string from those preferences title01Span.innerHTML = yourtitle01; // replaces the span.id with that text but I need to be able to do this in the src / href / url / etc. [CODE] Thank you so much! I seriously could use as much help as possible! Hey all, I'm trying to add rel="lightbox" somewhere in the slideshow I have on my client's site slideshow [www.bobbovanstudio.com/work.php] but anything I try is unsuccessful. Slideshow javascript piece for the picture's link: Code: this.hotlink = function() {
// This method jumps to the slide's link.
// If a window was specified for the slide, then it opens a new window.
var mywindow;
// If this slide does not have a link, do nothing
if (!this.link) return;
// Open the link in a separate window?
if (this.target) {
// If window attributes are specified,
// use them to open the new window
if (this.attr) {
mywindow = window.open(this.link, this.target, this.attr);
} else {
// If window attributes are not specified, do not use them
// (this will copy the attributes from the originating window)
mywindow = window.open(this.link, this.target);
}
// Pop the window to the front
if (mywindow && mywindow.focus) mywindow.focus();

Thanks in advance! Need some help here. I'm developing a non-server using form. The form sits on the users local computer, and generates an outlook email. There are boxes that are filled out, and each box is assigned a variable and gets transferred to an outlook email and gets plugged in to a pre-made email template. Here's what I'm trying to accomplish. I've been able to pre-populate the To: field using the variable var email = the CC: field using the variable &cc= and the BCC: field using the variable &bcc= . It would make sense that &from= or even &from: would work, but it doesn't. Appreciate the help. Hello, recently I have been to many government websites where I have noticed that the programmer has used window.open() method in JavaScript to link to different pages instead of using <a> tags! I was just getting curious to know whether it is normal or has it been used due to security concerns(if any, I don't know)? Any comments? Hello, I run a online gaming website, and I'm having problems with certain websites iframing our games. Actually I'm ok with iframing, as long as they include the banner ad located just beneath our games. But often times unscrupulous webmasters will iframe only the game, preventing us from generating any revenue from the banner ad (and costing us additional bandwidth charges). I'm hoping to find a way to detect the dimensions of the iframe, so that I may dynamically resize the game, in order to include the banner ad within the iframe. Does anybody know how to extract the "height" and "width" attribute values from an <iframe> tag sitting on a different site? Regards, Steve Hi all, I'm having a bit of a problem..

if its possible to make it do both in 1 function, please show an example. if you have to use 2 functions, then also show me an example. ANY help is GREATLY appreciated! From a database, I have a form that shows a list of items. These items have an order number that I can change on this form . I like to make a very simple button, that just adds +1 to the current values in the fields. The form fields are all named the same, "OrderNo" and let's call the form "MyForm", and the fields contain a number. In total there's about 20 input fields (all "OrderNo"), but it can sometimes be more or less. So in simple: A 1-click button, that adds "1" to ALL the field values. It sounds simple (and I think it has to be??), but cannot seem to figure it out. Anyone a suggestion on this? Thanks in advance! Hi All, I am very new to HTML programming and Javascripts. What I am trying to accomplish is I have a radio button "RequiredApprovalYesNo". When the selection is "Yes", I need fields "Approver" and "ApproverEmail" to be required upon submit. I also need to make sure that a selection is made with this radio button of either Yes or No. Here is my HTML code for these three fields and was wondering if someone could show me how to code this script or, give me an example of a Radio button selection resulting in additional fields being required or not. Thank you in advance. Code: <td>
<input type="radio" name="RequireApprovalYesNo" id="RequireApprovalYesNo" value="Yes">Yes
<input type="radio" name="RequireApprovalYesNo" id="RequireApprovalYesNo" value="No">No

Hi guys, I have a JS calculator on my website which is basically a load of radio buttons that the user clicks and as they do so a price is calculated in their view. At the moment - the price box starts with a blank box but is essentially "0". Then, as the user select an option, the price appears and then starts to calculate when more than 1 is pressed. All I want to do is have the price start at "300" instead of a blank box or "0". Then the rest of the options calculate onto that. I have tried a variety of ways to achieve it and seem to be missing something! I am pretty new to JS although do have a basic understanding ..... clearly not enough to do this thou! lol Basically imagine 300 is the initial price. That only gets charged once ... Here's my code .... In the <head> Code: <script type="text/javascript">
function getRBtnName(GrpName) {

var fnd = -1;
var str = '';
for (var i=0; i<sel.length; i++) {
if (sel[i].checked == true) { str = sel[i].value; fnd = i; }
}
return fnd; // return option index of selection
// comment out next line if option index used in line above
// return str;
}

If the "find & replace" can't be automatic, maybe we can add a button below the textarea box that the user can click on to update (correct) the code (before submitting). I am not a programmer... so any specifics you can give me will be much appreciated. Thank you. I need to do an input text validation which include opening parenthesis and closing parenthesis, what I need to validate is the opening parenthesis match with closing parenthesis. Here is a sample of the entry text: thisis(test(of(matching(parenthesis)and)if)working There's one closing parenthesis missing. I would like to warn the user to correct it before submit, but not quite sure how to do it with javascript. Please advice. Thanks JT This is a common issue, however, I haven't found anything ( yet ) that points out a solution that I can find in my code. As usual, this site works with every single browser known to man ...........except for any version of IE. I have tried using IE's devel tools to no avail ....though I'm a complete newb, so that isn't saying much. Code??? Here's the section IE complains about: Code: function display(str)
{
var nodeList = xmlDoc.getElementsByTagName("item");
var cnt = 0;
var list = "<hr />";
for(var i=0; i< nodeList.length; i++)
{
cnt++;
// Get vars from XML
title = nodeList[i].getElementsByTagName("title")[0].childNodes[0].nodeValue;
author = nodeList[i].getElementsByTagName("author")[0].childNodes[0].nodeValue;
pubDate = nodeList[i].getElementsByTagName("pubDate")[0].childNodes[0].nodeValue;
call = nodeList[i].getElementsByTagName("call")[0].childNodes[0].nodeValue;
cover = nodeList[i].getElementsByTagName("cover")[0].childNodes[0].nodeValue;
link = nodeList[i].getElementsByTagName("link")[0].childNodes[0].nodeValue;
summary = nodeList[i].getElementsByTagName("summary")[0].childNodes[0].nodeValue;
style = nodeList[i].getElementsByTagName("class")[0].childNodes[0].nodeValue;
page = nodeList[i].getElementsByTagName("page")[0].childNodes[0].nodeValue;
category = nodeList[i].getElementsByTagName("category")[0].childNodes[0].nodeValue;
I opened this with Firebug and I see nothing of interest. Specifically, IE complains about line 86: Code: summary = nodeList[i].getElementsByTagName("summary")[0].childNodes[0].nodeValue;
Thanks for reading ~ Bub **** UPDATE ***** Well ...it looks like I can't have null values in any elements ( in the xml document ). How do you experts satisfy this requirement in an elegant fashion. Since there is no data for certain elements, I'm looking for a reasonable failover solution. Empty quotes? ..... still experimenting. A script produces the xml file from a database so some elements do not have data for certain child elements. **** UPDATE 2 ***** Using the Unicode non-breaking space in the xml file for empty child elements. Works, but if you have a cooler solution, let me know. Thanks! I have created a basic Javascript function to check that all fields in the contact form that are required have information from the user. It works fine with input fields but not with textarea. Even when I dont insert message into textarea, the script allows to submit the form. I have given the name for textarea "userinput". Could anyone look at the code, and tell me what could possible be wrong with it? Thank you so much. function required() { user_message=document.contact_form.userinput.value; user_name=document.contact_form.name.value; user_email=document.contact_form.email.value; user_phone=document.contact_form.phone.value; if (user_name=="" || user_email=="" || user_phone=="" || user_message=="") { document.getElementById("notification").innerHTML="Please enter all required fields"; return false; } else return true; } Hi there! I'm trying to load up an array of images in HTML5, which will mimic a "video". I've put together code for creating an array of images, which will be drawn by the draw() function, but I'm struggling to find the best way to achieve a setInterval ie make the "video" of images run at 30 fps. At present, when I click the "Draw" button, the images load up, one after the other, just as in a video, but I can't seem to control this loading up speed. Can anyone help? I'm sure I'm very close to a solution! Here is my code: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

. SOURCE: Here Code: 1 document.onmousemove = mouseMove;
2
3 function mouseMove(ev){
4 ev = ev || window.event;
5 var mousePos = mouseCoords(ev);
6 }
7
8 function mouseCoords(ev){
9 if(ev.pageX || ev.pageY){
10 return {x:ev.pageX, y:ev.pageY};
11 }
12 return {
13 x:ev.clientX + document.body.scrollLeft - document.body.clientLeft,
14 y:ev.clientY + document.body.scrollTop - document.body.clientTop
15 };
16 }
#1: How is it that "mouseMove" is assigned to "document.onmousemove" from right-to-left? What exactly is taking place here? #3: How can "mouseMove" be declared as a function afterwards? #3: I periodically see "e" being placed in functions. Is "ev" taking the place for "e"? If so is "ev" or "e" a global object? Where do they initially come from and how do they work? . Code: for(i=0;i<document.getElementsByName('checkresult_".$i."').length;++i){
if(document.getElementsByName('checkresult_".$i."')[i].checked){
thisurlext+=document.getElementsByName('checkresult_".$i."')[i].value;
checkedlength++;
if(i+1<document.getElementsByName('checkresult_".$i."').length){
if(document.getElementsByName('checkresult_".$i."')[i+1].checked){
thisurlext+='+';
