JavaScript - Continuous Loop?
Hi all!
I've been trying to figure this one out but am scratching my head..... So here's what I'm trying to do. Creat a continuous text fade-in / fade-out Basically I'm going to have a banner at the top of a page that loops through text from a db. So, I get my data and create the divs and a csv that I pass to js as an array, all good, that works. This is what it would look like: Code: <div id="div_one">
Text 1......
</div>
<div id="div_two">
Text 2......
</div>
<div id="div_three">
Text 3......
</div>
And then the js array is Array('div_1,'div_2','div_3') etc Now, this is where I'm getting mixed up, I want to loop that array of div id's and fade them in / out one by one, but I can;t seem to figure it out.... Here's what I've tried: Code: loop_running = false;
function start_loop(){
loop_running = true;
}
function end_loop(){
loop_running = false;
}
function loop(arr){
if(arr.length > 0){
for(i=0;i<arr.length;i++){
if(loop_running == false){
// set loop_running var to true
start_loop();
// fade in div
fadeIn(arr[i], 1000);
// pause for 3 seconds then fade out
var t = setTimeout("fadeOut('"+arr[i]+"'), 1000", 3000);
// now set another timer to end the loop after 5 seconds
var e = setTimeout("end_loop()", 5000);
}
// now check to see if we're at the end of our array, if we are we need to call this function again to repeate
if(i == arr.length){
// repeat
loop(arr);
}
}
}
}
But that just gets the first div and then stops after fading out.... I've tried other variations too but with no avail..... I need to be able to tell the for loop to take 5 seconds for every one, so as it's looping it'll get the first div (first one in the aray), fade it up over one second, pause for 3 seconds then fade out, then get the next index in the array and do it again until it gets to the end of the array then it'll repeat. Does anyone know what's wrong with the logic i'm using? I can't for the life of me see how to get this working. Any advise will be gratefully received as always! Similar TutorialsI'm new to Javascript and having some difficulty understanding why I cannot get this code to continuously loop the captions in the array on the screen. The first caption in the array with appear, hold as per the setTimeout cycle and then disappear, but the next caption never comes up. Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

I'm sure this is probably a simple fix, or at least I hope it is. So any assistance is appreciated. Thank you I am trying to run three continuous slideshows on the same page. The script I am currently using is written below. Can it be modified so I can run all three slides at once on the same page? <html> <head> <script type="text/javascript"> <!-- var image1=new Image() image1.src="firstcar.gif" var image2=new Image() image2.src="secondcar" var image3=new Image() image3.src="thirdcar.gif" //--> </script> </head> <body> <img src="firstcar.gif" name="slide" width="100" height="56" /> <script> <!-- //variable that will increment through the images var step=1 function slideit(){ //if browser does not support the image object, exit. if (!document.images) return document.images.slide.src=eval("image"+step+".src") if (step<3) step++ else step=1 //call function "slideit()" every 2.5 seconds setTimeout("slideit()",2500) } slideit() //--> </script> </body> </html> ***Solved***
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. [code] <h2 id="fly">Header</h2> <script type="text/javascript"> //Use "$" for linebreak //By default, set to just grab the text from element with ID="fly" message = document.getElementById("fly").innerHTML; // $ = taking a new line distance = 50; // pixel(s) speed = 200; // milliseconds var txt="", num=0, num4=0, flyofle="", flyofwi="", flyofto="", fly=document.getElementById("fly"); function stfly() { for(i=0;i != message.length;i++) { if(message.charAt(i) != "$") txt += "<span style='position:relative;visibility:hidden;' id='n"+i+"'>"+message.charAt(i)+"<\/span>"; else txt += "<br>"; } fly.innerHTML = txt; txt = ""; flyofle = fly.offsetLeft; flyofwi = fly.offsetWidth; flyofto = fly.offsetTop; fly2b(); } function fly2b() { if(num4 != message.length) { if(message.charAt(num4) != "$") { var then = document.getElementById("n" + num4); then.style.left = flyofle - then.offsetLeft + flyofwi / 2; then.style.top = flyofto - then.offsetTop + distance; fly3(then.id, parseInt(then.style.left), parseInt(then.style.left) / 5, parseInt(then.style.top), parseInt(then.style.top) / 5); } num4++; setTimeout("fly2b()", speed); } } function fly3(target,lef2,num2,top2,num3) { if((Math.floor(top2) != 0 && Math.floor(top2) != -1) || (Math.floor(lef2) != 0 && Math.floor(lef2) != -1)) { if(lef2 >= 0) lef2 -= num2; else lef2 += num2 * -1; if(Math.floor(lef2) != -1) { document.getElementById(target).style.visibility = "visible"; document.getElementById(target).style.left = Math.floor(lef2); } else { document.getElementById(target).style.visibility = "visible"; document.getElementById(target).style.left = Math.floor(lef2 + 1); } if(lef2 >= 0) top2 -= num3 else top2 += num3 * -1; if(Math.floor(top2) != -1) document.getElementById(target).style.top = Math.floor(top2); else document.getElementById(target).style.top = Math.floor(top2 + 1); setTimeout("fly3('"+target+"',"+lef2+","+num2+","+top2+","+num3+")",50) } } stfly() </script> [code] Ok, I'm nearly pulling my hair out with this one. I have been looking at this code for two evenings now, and rewrote it 4 times already. It started out as jQuery code and now it's just concatenating strings together. What I'm trying to do: Build a menu/outline using unordered lists from a multidimensional array. What is happening: Inside the buildMenuHTML function, if I call buildMenuHTML, the for loop only happens once (i.e. only for 'i' having a value of '0'.) If I comment out the call to itself, it goes through the for loop all 3 times, but obviously the submenus are not created. Here is the test object: Code: test = [
{
"name" : "Menu 1",
"url" : "menu1.html",
"submenu" : [
{
"name" : "menu 1 subitem 1",
"url" : "menu1subitem1.html"
},
{
"name" : "menu 1 subitem 2",
"url" : "menu1subitem2.html"
} ]
},
{
"name" : "Menu 2",
"url" : "menu2.html",
"submenu" : [
{
"name" : "menu 2subitem 1",
"url" : "menu2subitem1.html"
},
{
"name" : "menu 2subitem 1",
"url" : "menu2subitem1.html"
} ]
},
{
"name" : "Menu 3",
"url" : "menu3.html",
"submenu" : [
{
"name" : "menu 3 subitem 1",
"url" : "menu3subitem1.html"
},
{
"name" : "menu 3 subitem 1",
"url" : "menu3subitem1.html"
} ]
}
];
Here is the recursive function: Code: function buildMenuHTML(menuData,level) {
var ul;
if (level == 1) {
ul = "<ul id='menu'>";
} else {
ul = "<ul class='level" + level + "'>";
}
for (i = 0; i < menuData.length; i++) {
menuItemData = menuData[i];
ul += "<li>";
ul += "<a href='" + menuItemData.url + "'>" + menuItemData.name + "</a>";
if (typeof menuItemData.submenu != 'undefined') {
ul += buildMenuHTML(menuItemData.submenu,level + 1);
}
ul += "</li>";
}
ul += "</ul>";
return ul;
}
Here is how the function is called initially: Code: buildMenuHTML(test,1); This is it's return value (with indentation added for readability): Code: <ul id='menu'>
<li><a href='menu1.html'>Menu 1</a>
<ul class='level2'>
<li><a href='menu1subitem1.html'>menu 1 subitem 1</a></li>
<li><a href='menu1subitem2.html'>menu 1 subitem 2</a></li>
</ul>
</li>
</ul>
'Menu 2' and 'Menu 3' don't show up! I'm sure it's something small that I'm overlooking, but any help would be appreciated. Hi all I'm well aware that I can't post assignments here and expect an answer, however, I have been staring at this code for so long. I feel I am close to the solution (to get the correct output to the browser) but I just cannot get it to count how many moves it takes. I don't want an answer, but a nudge in the right direction would be very grateful. As you can see from the code and the output, it will attempt to write to the browser how many moves, but only '0'. Code: function rollDie()
{
return Math.floor(Math.random() * 6) + 1;
}
/*
*searches for a number in a number array.
*
*function takes two arguments
* the number to search for
* the number array to search
*function returns the array index at which the number was found, or -1 if not found.
*/
function findIndexOf(number, numberArray)
{
var indexWhereFound = -1;
for (var position = 0; position < numberArray.length; position = position + 1)
{
if (numberArray[position] == number)
{
indexWhereFound = position;
}
}
return indexWhereFound;

Many thanks. Hello... Thanks for reading... I am getting an undefined error when i try to get a value from this array in the interior loop... Code: // This is the array I am trying to access AuditTable [0] = ["Visio Modifed date","Word Modified Date","User Status","User Comment","Last Audit","Audit Status","Audit Comment"] AuditTable [1] = ["11/23/2009 8:52:18 AM","missing","OK","user comment number 1","1/1/2009","ok","audit comment number 1"] AuditTable [2] = ["11/24/2009 12:21:19 AM","missing","Out of Date","Changes from 2008 not implemented","1/2/2009","Out of Date","needs update"] AuditTable [3] = ["11/22/2009 9:24:42 PM","missing","Incomplete","Document doesnt cover all possibilities","1/3/2009","Inadequate","needs update"] I have hard coded values and had success such as: Code: data = AuditTable[1][0] But when I put the vars associated with the loop in I get an undefined error - AuditTable[i] is undefined: Code: // produces error data = AuditTable[i][j] //Works but retrieves wrong data data = AuditTable[j][i] //Works but retrieves wrong data data = AuditTable[1][i] //Works but retrieves wrong data data = AuditTable[j][2] I must be trying to access the array incorrectly or something... I have defined all the vars, and tried many combinations, alerted the values of both vars so I can prove it is not a scope issue... Am I missing something obvious? Thanks much... Code: var reportArray=new Array();
var reportData, title, subTitle, data;
for(i in parmarray)// loop thru AuditTable array and get values
{
title = '<div style="font-family:verdana; font-size:14px; font-weight:bold; margin:25px 0px 5px 30px">';
title += namearray[i][0];
title += '</div>';
reportArray.push(title);//Take compiled variable value and put it into array
for(j=0; j < AuditTable[0].length; j++)// loop thru AuditTable array and get values
{
subTitle = AuditTable[0][j];//points to first row of AuditTable where the labels are
data = AuditTable[1][0];//points to the current row where actual data is

it wont loop, as long as you enter something in the name field it will submit. also how do i stop from submitting if all fields are not filled out? any help will be appreciated) ====== function checkForm(form) { var len = form.elements.length; var h=0; for (h=0; h<=len; h++){ if ((form.elements[h].value==null) || (form.elements[h].value=="")){ alert("Please enter "+document.myForm.elements[h].name); document.myForm.elements[h].focus(); return false; } return true; } } ===body-== <FORM NAME="myForm" METHOD="post" ACTION="http://ss1.prosofttraining.com/cgi-bin/process.pl"> Name:<BR> <INPUT TYPE="text" size="30" NAME="name"><br> Email address:<BR> <INPUT TYPE="text" size="30" NAME="email address" onBlur="emailTest(this);"><br> Phone number:<BR> <INPUT TYPE="text" size="30" NAME="phone number"><br> Fax number:<BR> <INPUT TYPE="text" size="30" NAME="fax number"><p> <INPUT TYPE="submit" VALUE="Submit Data" onClick="return checkForm(this.form);"> <INPUT TYPE="reset" VALUE="Reset Form"> </FORM> Hi, I am doing some studying and we was to create a small loop using either the for loop, while loop or do while loop. I chose to do the for loop because it was easier to understand, but I want to know how to do the same using the while loop. Here is the for loop I have, but I cant figure out how to change to while loop. Code: for (var i = 0; i < 5; ++i)
{
for (var j = i; j < 5; ++j)
{
document.write(j + "");
}
document.write("<br />");
}
output is equal to: 01234 1234 234 34 4 How do you make the same using a while loop? Hey guys i've just been following a few tutorials and learnt how to do a for loop and a while loop, what is the major difference between the two? they seem quite similar? I know while loops are laid out a hell of a lot easier in my opinion!
For those who read my other thread I finally scratched together the code to take a value from an XML file and add it to a select box as an option. Ofcourse it only does it once so I need to loop it. It's kinda complex though, here's a function line to add one option: addOption(document.people_form.People,name2,office2) And here's the code in the head: <script type="text/javascript"> //load xml file if (window.ActiveXObject){ var xmlDoc = new ActiveXObject("Microsoft.XMLDOM"); xmlDoc.async=false; //Enforce download of XML file first. IE only. } else if (document.implementation && document.implementation.createDocument) var xmlDoc= document.implementation.createDocument("","doc",null); if (typeof xmlDoc!="undefined") xmlDoc.load("namedata.xml"); //Regular expression used to match any non-whitespace character var notWhitespace = /\S/ function getnames(){ //Cache "messages" element of xml file var nameobj=xmlDoc.getElementsByTagName("list")[0] //REMOVE white spaces in XML file. Intended mainly for NS6/Mozilla for (i=0;i<nameobj.childNodes.length;i++){ if ((nameobj.childNodes[i].nodeType == 3)&& (!notWhitespace.test(nameobj.childNodes[i].nodeValue))) { // that is, if it's a whitespace text node nameobj.removeChild(msgobj.childNodes[i]) i-- } } } if (typeof xmlDoc!="undefined"){ if (window.ActiveXObject) //if IE, simply execute script (due to async prop). getnames() else //else if NS6, execute script when XML object has loaded xmlDoc.onload=getnames } var name2=xmlDoc.getElementsByTagName("name")[0].firstChild.nodeValue; var office2=xmlDoc.getElementsByTagName("office")[0].firstChild.nodeValue; var officePH2=xmlDoc.getElementsByTagName("officePH")[0].firstChild.nodeValue; var mobile2=xmlDoc.getElementsByTagName("mobile")[0].firstChild.nodeValue; var email2=xmlDoc.getElementsByTagName("email")[0].firstChild.nodeValue; </script> <script type="text/javascript"> function addOption(selectbox,text,value ) { var optn = document.createElement("OPTION"); optn.text = text; optn.value = value; selectbox.options.add(optn); } </script> Could anyone give me a pointer on how to loop this so that it loads one option after another from the XML file? Thanks. I have a form that shows or hides divs based on what is chosen in a dropdown. There are 4 divs but only one is shown and the other 3 hidden based on dropdown selection. Inside each div are checkboxes with items for sale. I want to reset the checkboxes to unchecked and the line total values to 0 if the div is hidden. I've got the checkboxes to reset but I can't figure out how to set the line total values to 0 (There are 14 total so I'm trying to loop thru all of them and reset them.) This is what I have in the loop Code: for (var i = 0; i < form.elements.length; i++ ) {
if (form.elements[i].type == 'checkbox') {
form.elements[i].checked = false;
}
}
// set line_totals to 0
for (var j = 0; j< form.elements.length; j++ ) {
if (form.elements [j].name.substring(0,10) == 'line_total') {
form.elements[j].value = '';
}
}
I have the following code which is almost completely working the way I need it to with the exception of the "downloadFile" value...

if( !links[i].href.match(onsiteDomains) ){
unobtrusiveAddEvent( links[i], 'onclick' , function() { ntptEventTag('lk=1&ev=Exit Link'); });
}
}
}
...how do I grab the value of the href that was just clicked? links[i] is not working (it's just grabbing the href value of the last href in the loop). I am missing something simple for sure. Can anyone point out what I am missing? Thanks! Hello, I recently purchased a JavaScript book, and I am confused by one of it's examples. I was wondering if anybody could answer my question. Here is the example: for (loopCounter = 1; loopCounter<= 3; loopCounter++) { //execute this code } Now, what I need help with is the variable part. The book goes on to say: ""To keep track of how many times you have looped through the code, you need a variable to keep count" My question is: Why does the variable have the value of one and not another number? I'm very very new to JS, I understand that the loopCounter has to be les than or equal to 3 for the code to execute, and also that it is incremented by one each loop, but the book is not clear on why the value of the variable has been set to 1. If anybody could answer this question I would be very grateful, I hate moving onto the next stage of a book if I do not completely understand the previous topics. Thank you in advance Hello all. I am faitly new at programming and have run into a little problem. I want to create a script that creates 2 random numbers, stored in 2 different variables and then compare them to eachother. there is two possible outcome of that comparison, either they are different or they are alike. If they are different i want to randomize a new set or numbers and make a other comparement, also to keep track on how many times i have created numbers. If they are alike i want to display the numbers and how many tries it took to get a matching pair. atm it looks like this <html> <body> <script> var x=(Math.floor(Math.random()*6)+1); var y=(Math.floor(Math.random()*6)+1); //creates two random int between 1 and 6 var throws = 1; //keep tabs on how many times we have thrown the dices if(x!=y) { x=(Math.floor(Math.random()*6)+1); y=(Math.floor(Math.random()*6)+1); throws=throws+1 }else{ document.write("you have rolled a pair. Dice 1 is: " +x +" and Dice 2 is: " +y +" and it took " +throws +" tries to get a pair."); } </script> </body> </html> How to get that into a loop? a really confused newbie scripter Hi All, im trying to to use a for loop to loop through a drop down list of users and if there is a match between the user logged in and the drop down list i want to enable two fields, if the user logged in isnt in the drop down list i want to disable the two fields, but im having trouble looping through, iv tried ".value" with no avail.. heres my Script Code: var RequestingUser = document.getElementById('JoinersLeaversContent_cmbRequestingUser').text;
var Authorisers = document.getElementById('JoinersLeaversContent_ddlAuthoriseId');
for (var i = 0; i < Authorisers.length; i++)
{
if (RequestingUser.text == Authorisers.value) {
document.getElementById('JoinersLeaversContent_txtAuthoriserSig').disabled = false;
document.getElementById('JoinersLeaversContent_txtDateSignedOff').disabled = false;
}
else
{
document.getElementById('JoinersLeaversContent_txtAuthoriserSig').disabled = true;
document.getElementById('JoinersLeaversContent_txtDateSignedOff').disabled = true;
}
}
So just to be clear, if the user logged in appears in the drop down box i want to enable the two fields, if they dont appear i want to disable the two fields Please help. Thank you Ok so I have these elements on my page: Code: <input type="text" size="5" name="val[]" value="'.$NotaMaxima.'"> I want to loop through each one and take their number add it to another number set in a variable elsewhere and then alert that number. The amount of these elements on the page changes constantly, so I can't count on that. It has to loop through each one to find the values. I tried this: Code: var els,i,asig;
els=document.getElementsByTagName('val');
for(i in els) {
asig = parseInt(els[i].value) - parseInt(asig);
}
alert(asig);
But no go, any ideas? hi there here's my problem, I want to alert each innerHTML of the tag "a" when mouse over, but it only alert when i insert "return false;" in the end of the loop, what's the problem?

I have a dice rolling function. The user enters the number of sides, and the dice rolls 36000 times. I track the results, and then display the percentages of each number being rolled as well. I have it to where it displays but only for ONE die ( eg : a 5 sided die, it only displays up to 5, and not 10 ) But the function is rolling for both die, just not displaying. I'm thinking I need to change, in the rollDice function, <=d.side to <=rolled_value, but whenever I do this, I get NaN errors. Any help would be appreciated! Code:
<script type="text/javascript">
function Die(side) {
this.side = side;
