JavaScript - Duplicating An Element
Im trying to duplicate an image multiple times here is what I have
Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<script type="text/javascript">
var totalNumber = 1000;
function insert(num) {
var cont = document.getElementById("cont");
var img = document.createElement("img");
var percent = num/totalNumber;
var result = cont.offsetWidth * percent;
var dup = result/100*2;
img.src = "guy.jpg";
cont.appendChild(img);
}
</script>
<style type="text/css">
#cont {height:100px; width:500px;}
</style>
</head>
<body>
<div id="cont"></div>
</body>
<script type="text/javascript">
insert(3000);
</script>
</html>
So Im trying to get img to repeat the variable "dup" so you would see <img src="guy.jpg"> 30 times. Similar TutorialsOkay, so I've created a JavaScript form which allows the user to enter their name into the form and display it within the sentence, "Welcome to the site ______". It works on one page, but, problem is, I'd like it to be displayed on every page. I'm aware you cannot do this with getElementbyId (can only be used once), which is what I've used. I've tried using getElementsbyClass, but from my understanding, it's not as simple as that. Here's my code so far anyway: Code: <script type="text/javascript">
function inputname(){
var userInput = document.getElementById('userInput').value;
document.getElementById('welcome').innerHTML = userInput;
}
</script>
Code: <p>Welcome to the site <b id='welcome'></b> </p> <input type='text' id='userInput' /> <input type='button' onclick='inputname()' value='Enter Name'/> Dear all, Below are my current script. I need another few more sets of the triple drop down menu same as the below script... (Scenario: creating like a online shopping order form, where customers can have multiple orders.) Please guide me how to do so.. Thank you in advance. <script type="text/javascript"> /* Triple Combo Script Credit By Philip M: http://www.codingforums.com/member.php?u=186 Visit http://javascriptkit.com for this and over 400+ other scripts */ var categories = []; categories["startList"] = ["Wearing Apparel","Books"] categories["Wearing Apparel"] = ["Men","Women","Children"]; categories["Books"] = ["Biography","Fiction","Nonfiction"]; categories["Men"] = ["Shirts","Ties","Belts","Hats"]; categories["Women"] = ["Blouses","Skirts","Scarves", "Hats"]; categories["Children"] = ["Shorts", "Socks", "Coats", "Nightwear"]; categories["Biography"] = ["Contemporay","Historical","Other"]; categories["Fiction"] = ["Science Fiction","Romance", "Thrillers", "Crime"]; categories["Nonfiction"] = ["How-To","Travel","Cookbooks", "Old Churches"]; var nLists = 3; // number of select lists in the set function fillSelect(currCat,currList){ var step = Number(currList.name.replace(/\D/g,"")); for (i=step; i<nLists+1; i++) { document.forms['tripleplay']['List'+i].length = 1; document.forms['tripleplay']['List'+i].selectedIndex = 0; } var nCat = categories[currCat]; for (each in nCat) { var nOption = document.createElement('option'); var nData = document.createTextNode(nCat[each]); nOption.setAttribute('value',nCat[each]); nOption.appendChild(nData); currList.appendChild(nOption); } } function getValue(L3, L2, L1) { alert("Your selection was:- \n" + L1 + "\n" + L2 + "\n" + L3); } function init() { fillSelect('startList',document.forms['tripleplay']['List1']) } navigator.appName == "Microsoft Internet Explorer" ? attachEvent('onload', init, false) : addEventListener('load', init, false); </script> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>Untitled Document</title> </head> <body> <form name="tripleplay" action=""> <select name='List1' onchange="fillSelect(this.value,this.form['List2'])"> <option selected>Make a selection</option> </select> <select name='List2' onchange="fillSelect(this.value,this.form['List3'])"> <option selected>Make a selection</option> </select> <select name='List3' onchange="getValue(this.value, this.form['List2'].value, this.form['List1'].value)"> <option selected >Make a selection</option> </select> </form> </body> </html> Evening all, I am new here and seeking some helping modifying this existing code that I found so that it will allow me to run 3 scrollers within the same page.

I will include this within a php page and the menu contents will be dynamically pulled from a database, I can handle populating the menucontents however, I have failed to be able to have more than one scroller on the page at once.

What it's saying isn't actually true (I don't think)... this is how the section is laid out: Code: <div id="submenu1" class="anylinkcss"> <ul> <li class="contact-pm"><a href="/index.php?do=pm&act=new&to=$RateViewProfileUserName$&returnurl=$ReturnURL$">PM me</a></li> <li class="contact-email"><a href="/index.php?do=email&id=$RateViewProfileUserId$">E-mail me</a></li> <li class="contact-msn" id="msn1">$RateViewProfileUser-profile_msn$</li> <li class="contact-yahoo" id="yahoo1">$RateViewProfileUser-profile_yahoo$</li> <li class="contact-skype" id="skype1">$RateViewProfileUser-profile_skype$</li> <li class="contact-facebook" id="facebook1"><a href="$RateViewProfileUser-profile_facebook$"><span id="fbook-add"></span></a></li> </ul> </div> <script type="text/javascript" src="/html_1/js/contact-information.js"></script> Does anyone know why this might error in just IE? Hi, I'm relativly new to JS and brand new to the forum so you might need to dumb down your replys for my slightly lacking knowledge. That being said I do have a very solid grasp of html, css and am getting there with JS and its various frameworks. I'm integrating wordpress into an existing site for a friend and currently have the main blog page appear in a DIV. This is the best way to integrate in this case due to many reasons mostly of way the site is constructed. Code: <div class="scroll-pane" id="scrollbox"> WORDPRESS BLOG </div> My issue is that links within that DIV, in the blog, when clicked redirect the page. The simple answer to this would be to have them just open in a new page, which I can easily do with the below code. Code: function Init()
{
// Grab the appropriate div
theDiv = document.getElementById('scrollbox');
// Grab all of the links inside the div
links = theDiv.getElementsByTagName('a');
// Loop through those links and attach the target attribute
for (var i=0, len=links.length; i < len; i++) {
// the _blank will make the link open in new window
links[i].setAttribute('target', '_blank');
}
}
window.onload = Init;
But what I'd rather it do is have any link clicked inside the DIV to reload in that same DIV, similar to an iframe, but obviously without using an iframe, due to it's compatibility issues. Is this possible by editing the above code? If not what do I need? Thanks in advance for any help! I have the following code Code: <div class="thdnrml"> <td><a href="somelink">fonfof</a></td> </div> what i want to do is this: Code: <div class="thdnrml"> <td><a href="somelink">fonfof</a><a href="anotherlink">another_link</a></td> </div> how can i go about achieving this? Hi, (new to javascript) Code: digAudio = document.createElement("audio");
digAudio.setAttribute('src',hypeDocument.documentName()+'_Resources/'+'digging.m4a');
digAudio.id = "diggingAudio";
newAudio = document.getElementById("diggingAudio"); //returns null
the audio element is added (I can play the audio) but I can't get it by its id ? thank you Hi I have DropdwonList with elements, 1,2,3 and 4.. and I have another DropdownList with options Normal, Standard, Emegency, and Expendited. Can you help me with a code, so that when I select "1" option on the first dropdown, the "Emegency" option on the second dropdown is set/selected. Thanks in advance Hello I am fairly new to Javascript and found this code online but can't seem to get it to work right. here is the code I am using it is suppose to apply a style attribute the the id "toplink" but I can't seem to get it to work right. Code: $(document).ready(function(){
menuYloc = parseInt($(name).css("top").substring(0,$(name).css("top").indexOf("px")))
$(window).scroll(function () {
var offset = menuYloc+$(document).scrollTop()+"px";
$("#toplink").animate({top:offset},{duration:500,queue:false});
});
});
Thanks in advance So, I have this javascript that works just fine... But... PHP Code: <script language="javascript"> function addBtn() { element = document.createElement("input"); element.setAttribute("type", 'button'); element.setAttribute("value", 'Track'); element.setAttribute("name", 'element'); element.onclick = function() { alert("Tracking"); }; var btn = document.getElementById("gs-track-btn"); btn.appendChild(element); } </script> <div id="gs-track-btn"></div> How would I target that div if the " gs-track-btn " id was a class? I am using a jQuery slider for a website but the W3C comes up with invalid because: document type does not allow element "div" here .before('<div id="buttons">') Code: <script type="text/javascript">
$(document).ready(function() {
$('#slider')
.before('<div id="buttons"></div>')
.cycle({
fx: 'fade', // choose your transition type, ex: fade, scrollUp, shuffle, etc...
pager: '#buttons'
});
});
</script>
Any help with this would be appreciated thanks. I'm trying to add an input element to all forms using appendChild. The script first searches for input elements with the name of "myinput". If it finds an input element with that name, it assigns the value "myvalue". If it can't find an input element with that name, it tries to create a new one for all forms. Code:
if (document.getElementsByName('myinput')) {
var testcode = document.getElementsByName('myinput');
for (var i=0; i < testcode.length; i++){
testcode[i].value = "myvalue";}
}
else {
var z = document.createElement("input");
z.type = "hidden";
z.name = "myinput";
z.value = "myvalue";
z.id = "mycode";
var d = document.getElementsByTagName('form');
for (var i=0; i < d.length; i++){
d.appendChild(z);}
}
What's wrong with my code? Thanks! Hi, Would someone here please help me with this script. I know I am a complete hack at this, but I need to get it to work. Your help is appreciated. As you can see, based on the if statement, I need to leave the Div element below hidden, or un-hide it. I know the first part works. The second part (after "else" ) is where I am having the problem. Code: <td>
<script type="text/javascript">
if ([fieldXX]==1)
{
document.write("<a href='page1.asp?itemid=1234'><img src='images/btn-choose.gif' border='0' alt='choose button'</a>");
}
else
{
var id = 'hide-buy-btn';
var item = document.getElementById(id);
if (item) {
item.className=(item.className=='hidden')?'unhidden':'hidden';
}
}
</script>
<div id="hide-buy-btn" class="hidden">
x
xother button code
x
</div>
</td>
Hello. I am setting up a simple registration page for a community arts project, but I am new to JS and having some issues. Right now I have a list of check boxes like this: Code: <input type="checkbox" id="HA0001" onclick="updateTotal()" /> Wendy Day <input type="checkbox" id="HA0002" onclick="updateTotal()" /> Al Benne <input type="checkbox" id="HA0003" onclick="updateTotal()" /> Julie Steppe What I would like to do is GET the input boxes ID value - which will be different for every checkbox. That value will correspond with a variable of the same name in my javascript code, that will be added or subtracted from the users total cost. So when a box is clicked, I need my variable (called "currentId") to update to the ID value, such as "HA0001" - etc. I was thinking something along the lines of this, but I know it is incorrect: Code: var currentId = document.getElementById.id; All the other add/subtract stuff I will figure out, but I am having a problem getting the ID value from a checkbox when it is clicked. Can anyone help me figure this out? THANKS! -AJ 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 ?
}
Hi all Not sure how to tackle this. I haven't done any DOM manipulation and this is a tag within a tag. Another thing is submit is Ajax and therefore can be hit many times --- so I guess I need to also check if element already exists. The result comes back from PHP and I think wipes out anything in the result area. I want to create this: Code: <span id="loading"><img src="loading.gif" /></span> Code: <div id="results">which should populate here</div>
<script type="text/javascript">
function loading(){
?
</script>
<input type="button" name="submit" id="submit" onclick="loading();"/>
How do I begin this? Help appreciated. LT oh this is my Ajax just in case what i'm trying to do should be done from here. Code: <script type="text/javascript">
$(document).ready(function() {
$('#submit').click(function(){
//Get the values
var amount = $('#amount').val();
var from = $('#from').val();
var to = $('#to').val();
var params = "amount=" + amount + "&from=" + from + "&to=" + to;
$.ajax({
type: "POST",
url: "change.php",
data: params,
success: function(data){
$('#results').html(data).fadeIn("slow");
}
});
});
});
</script>
Hi all i have the following code. Code: $(document).ready(function(){
$("ul, li, a, p, img").hover(
function(){
var origBorder = $(this).css("border");
var elementID = $(this).attr("id");
$(this).css("possition", "absolute").css("z-index", "100").css("border", "1px solid red");
},
function(){
$(this).css("border", "none").css("z-index", "1");
}
);
});
it is suposed to outline the element that i am hovering over. Yet if I hover over say an <li> it will outline the li and the ul. Any ideas on how to just outline the element im hovering over? I am trying to have it so that when someone choose a value from the select box, it then displays it in the html. The problem is im not very good with javascript, and my error keeps coming up as undefined where as before it was coming up as "[object HTMLSelectElement]". Can anyone tell me whats up? PHP Code: <html> <head> <script type="text/javascript"> function moveValue() { var no=document.getElementById("no"); var option=no.options[no.selectedIndex].numberr; document.getElementById('numberr').innerHTML = option; } </script> </head> <body> <form> Select numbers:<br /> <select id="no"> <option>0</option> <option>1</option> <option>2</option> <option>3</option> <option>4</option> <option>5</option> <option>6</option> <option>7</option> <option>8</option> <option>9</option> </select> <input type="button" onclick="moveValue()" value="-->"> <i id="numberr">Testing</i> </form> </body> </html> and now that i look at it, i suspect that the reason that it is not working is that i should have "ID"'s or value's on each of the options but i do not know for certain HI I want to write a search for my site .I make a new panel in the left of my menue and it has a text input and an image which when that user click on it javascript opens a new window which is a php page.The part I don't know how to do is when the user click on the image it should get the content of the text input and pass it to the url.For the hyperlink of the image I use "<a href="javascriptpen_window('includes/func/search.php?id=" But I don't know what should I write after that to get the content of the text input and put it in the next of the id. How can I do so? Thanks Alright, this is going to sound strange, but bear with me here... Code: <input type="text" name="_F0827U" size="015" maxlength="015"> <input type="submit" class="cmdkey" name="_K040827" value="..."> Say I have multiple isntances that look similar to the above. However, I have no possible way of identifying them uniquely (because I don't know the name prior to generation). Is it posable, using JS, to snag the previous element and strip it of it's tags then rewrite a new element isntead of the two originals, say using an onClick() event on either of the elements? |
