JavaScript - Cloning Multiple Form Elements
Hello,
I'm in need of some help. I have a form that I want to clone and add up to 5 duplicates with slight changes. The changes a Add a second question and another set of related radio buttons for only the duplicates. Change the title in the Header to increment by 1 ex. Header 1, Header 2... I also would like to make the form elements "id" and "names" unique. Also, continue to use the add and remove button at the bottom. I hope this is doable. Any help will be appreciated. I have included my existing code. NOTE: for a visual, I mocked up the the original form and 1 copy of the fields in the html, not to be used.

-Cheers Similar TutorialsI have something like this var oneTest = new CustomObj({ prop1 : 'value1', prop2 : 'value2', prop3 : 'value3' }) var twoText = Object.clone(oneTest) twoText.prop2 = "newvalue2" And when I console log twoText I see something like +Data prop2 Inside Data is a prop2 that has the value of "value2". THAT is the one I want to change/override... yet the console shows me that the prop2 is outside of the data structure so when I am acting on the cloned obj I am not getting the results i need. I tried obj.extend etc.... and that didn't work, perhaps my syntax was wrong. Any advice? Normally I would just use document.getElementById to get anything I need but here is my problem: I have a zip code control that I load using AJAX. it has city, state, country, county and zip code. This gets loaded within a business application and at one point you can have both a bill to and ship to address forms on the screen at the same time, loading my zip control with the same fields, same ids and same name. This forced me to now pass in the form name that contains the control. I need to get to divs and spans within this form. Primarily as you type in a city or zip code, I am doing a hot search with a popup div that shows you results you can quickly choose from. The only time this becomes an issue is the situation I mentioned before when the zip code control is on the screen twice. I am not certain how to access the innerHTML of a span or div by way of the form name. Is this possible and if so what is the proper syntax? Here is a very basic example at its simplest form of my problem. Code: <form name="frm_billto" id="frm_billto"> <span id="myspan">Hello</span> </form> <form name="frm_shipto" id="frm_shipto"> <span id="myspan">World</span> </form> In the above example because the control was loaded twice, I now have 2 spans with the same ID. I want the innerHTML of the each span based on the form they are in. We wanted one control that we could use throughout the system that we could update in one place and the entire application be updated. Unfortunately we did not anticipate having it load more than once on the page. Thank you for any help I'm having a problem with the <CANVAS> element in JavaScript. here's what i'm trying to do: I need 3 different canvas elements for writing a signature to. they must all 3 be visible at the same time My problem that i'm having is that i can't seem to get the code to work which will write to more than one canvas. here's my code: Code: <html>
<head>
<script language="javascript">
function WriteSignature(element, event)
{
document.addEventListener("mousemove", PenHandler, true);
document.addEventListener("mouseup", upHandler, true);
event.stopPropagation();
event.preventDefault();
function PenHandler(event)
{
var x = event.clientX;
var y = event.clientY;
// mouse event goes here
var canvas1 = document.getElementById("Canvas1");
var ctx = canvas1.getContext("2d");
var PenSize = 2;
ctx.fillStyle = "Black";
ctx.fillRect (x, y, PenSize, PenSize);
event.stopPropagation();
}
function upHandler(event)
{
document.removeEventListener("mouseup", upHandler, true);
document.removeEventListener("mousemove", PenHandler, true);
event.stopPropagation();
}
}

hi, I am now building my website as a final project for my year. I am doing graphic design, so the website is actually some kind of portfolio. The idea of this website (which is not yet online) is this : it is some kind of big pasteboard on which i will display all the work i have done in my academy since a couple of years. The pasteboard is at the moment a background image/color field of given dimension (i figure that was the only way to do what i wanted...see further) Every works/image load on a random place and then can be dragged, and dropped (this part i already figured out). At the moment, every image (for every project), is inside a <div>. What i need help for is this: at the moment, my function successfully load 1 element at random position. I now want this function to work separately, for every <div>, so that every image is randomly placed on load, on the background image (and not the browser window, which is smaller). Here is the code i have for the moment (sorry for the mess, i really am just beginning! and truely, i don't get half of this, i just know it is working at the moment): Code: <head>
<!--// function random start position-->
<script>
var aDOM = 0, ieDOM = 0, nsDOM = 0; var stdDOM = document.getElementById; if (stdDOM) aDOM = 1; else {ieDOM = document.all; if (ieDOM) aDOM = 1; else { var nsDOM = ((navigator.appName.indexOf('Netscape') != -1) && (parseInt(navigator.appVersion) ==4)); if (nsDOM) aDOM = 1;}}
function xDOM(objectId, wS) { if (stdDOM) return wS ? document.getElementById(objectId).style: document.getElementById(objectId); if (ieDOM) return wS ? document.all[objectId].style: document.all[objectId]; if (nsDOM) return document.layers[objectId]; }
// More Object Functions
function setObjVis(objectID,vis) {var objs = xDOM(objectID,1); objs.visibility = vis;}
function moveObjTo(objectID,x,y) {var objs = xDOM(objectID,1); objs.left = x; objs.top = y;}
// Browser Window Size and Position
function pageWidth() {return window.innerWidth != null? window.innerWidth: document.body != null? document.body.clientWidth:null;}
function pageHeight() {return window.innerHeight != null? window.innerHeight: document.body != null? document.body.clientHeight:null;}
function posLeft() {return typeof window.pageXOffset != 'undefined' ? window.pageXOffset:document.documentElement.scrollLeft? document.documentElement.scrollLeft:document.body.scrollLeft? document.body.scrollLeft:0;}
function posTop() {return typeof window.pageYOffset != 'undefined' ? window.pageYOffset:document.documentElement.scrollTop? document.documentElement.scrollTop: document.body.scrollTop?document.body.scrollTop:0;}
// Random Position Script
var xxx = Math.floor(Math.random()* (pageWidth()-230));
var yyy = Math.floor(Math.random()* (pageHeight()-50));
function start()
{var x = (posLeft()+xxx) + 'px';
var y = (posTop()+yyy) + 'px';
moveObjTo('myobj',x,y);
setObjVis('myobj','visible');}
window.onload = start;
window.onscroll = start;// JavaScript Document
</script>
</head>
<body bgcolor="#9A9B95" background="../website/background.jpg">
<div id="myobj" style="position:absolute" >
<img src="oblique strategies holes.jpg" width="595" height="842" style="position:absolute" class="dragme"/>
</div>
<div id="div2">
<img src="oblique strategies choices.jpg" width="842" height="595" style="position:absolute" class="dragme" />
</div>
</body>
now, what i really want is this function to work for every <div> but i know there are also some flaws (that i'm unfortunately unable to fix myself): the integers "230 and 50" in the "random position script" should be replaced byt the width and heigh of the image/div (so i guess i should find a function that can get those numbers, name them "ImgWeidth" and "ImgHeigh" so that those integer can be called in this "random position" function. also, once the div 'myobj' is loaded, randomly, it behaves like if position=fixed (so stays on the spot when i scroll down the window). I think this is because it calculates the position according to the browser window and not my background. this has be fixed, because i don't want all my images to load only in the browser window (but on the whole pasteboard/background image). well, i guess this is already 3 questions in one. so i will let it like that for the moment. Sorry if i'm saying too much/not enough... beginners mistake!:confused: thanks in advance for any help you will give me! Hello I've been struggling trying to get a small order form to work the way I want it to. Here is a link to the live page: http://www.watphotos.com/introductio...otography.html And here is the code in question: Code: <script src="js/jquery-1.4.2.min.js" type="text/javascript"></script>
<script type="text/javascript" charset="utf-8">
$(document).ready(function(){
var initial = 0
var total = 0;
var services = 0;
function addServices()
{
initial = 150
total = initial
services = 0;
$("input:checked").each(function(){
value = $(this).attr("value");
services += parseInt(value);
});
}
$(function()
{
addServices();
total += services;
$("form").before('<p class="price"></p>')
$("p.price").text("Total Price: US$" + total);
});
$("input:radio, input:checkbox").click(function () {
addServices();
total += services
$("p.price").text("Total Price: US$" + total);
});
});
</script>
I have two questions... Question 1 How can I make this piece of script act a little smarter. Look at the order form, I'm catering for up to 4 people and providing lunch for them. If they select 3 people and the spaghetti bol for lunch, it's only adding $10 where it should be adding $30. Obviously this is simple multiplication but since the values in my form are prices it makes it a little tricky. I'm guessing an onselect on the first part of the form which changes the pricing of the other items would be the way to go, but how do I do this? Question 2 The "Total Price" is placed before the <form> tag by the script. This is ok but it's not where I want it. How can I position this text elsewhere in the document? Thanks in advance! I'm using the jquery plugin found here. I love the look but I have a form that uses functions like this: Code: function cascadeCountry(value) {
if (document.getElementById("srchlookstate_province") != null) {
http.open('get', 'cascade_search.php?a=country&v=' + value );
document.getElementById('srchlookstate_province').innerHTML=" "+loadingTag;
http.onreadystatechange = handleResponse;
http.send(null);
}
}
So, when you select a country and it retrieves the state/province text input, the jquery css is not applied to it. Is there something I need to add to the code above or to the jquery initialization code he Code: $(function() {
$("form.jqtransform").jqTransform();
});
Hi Folks - I have a form that has an array of input values: <input type="text" name=txtValue[] /> <input type="text" name=txtValue[] /> I do this so I can loop through the values in php... now...that's the easy part... the hard part comes to this: next to each of those boxes is a search button that allows the user to open up a popup window that they can search for an item, and select the item. Once they select the item it should populate that particular input box with the selected item. I can easily do this with a uniquely named input box, but can't seem to figure out how to do it with an array of input boxes... any idea? Here is the code in question: Code: for (var x = 2; x < 6; x++) {
var form = document.playerAction["action" + proNum];
form[x] = null;
form[x] = z[x-2];
if (Player[x-1].health == 0) { form.splice(x-2,1) }
}
The code retrieves document.playerAction["action1"] (A select input type) and removes options 2-end (there is a max of 6). Then, if a certain player (x-1 causes it to loop 1-4) has a health of 0, it splices out that element). Everything works fine, except I get an error saying that "Object #<an HTMLSelectElement> has no method 'splice' " and it refuses to execute the if. How do I work around this? Hi there I have a form with elements named (& id) 1 through 5 Why can't I loop through all my form elements like this... Code: function toggle(){
for (var i=1;i<=5;i++)
{
var y = document.getElementById(i);
y.style.backgroundColor = '#FFFFFF';
}
}
The error I get is y is null??? If I hard code the id's like this... var y = document.getElementById('2'); it works fine?? Please Help NEWB Hi, I'm pulling my hair out to create a simple function! I am creating an array based on form elements. I then am trying to create an IF (and nested IF) statement to check if the fields are empty and then with the nested IF statement use certain fields to create mathematical functions. So far I have this: function QuantityMWh(form) { var formchk = document.forms[0] for (i = 0; i < formchk.elements.length; i++) { if (formchk.elements[1].value == "" && formchk.elements[2].value == "") { alert("Please fill out all fields.") break } } } It's only checking the first field and not the second, and vice versa. i.e. if only one field has text then it passes. What am I doing wrong? Thanks. Hi all. I have a form named "theForm". How can I loop through this form elements that have an "id" ATTRIBUTE to them and then populate my ids array? var ids = new Array; for(i=0; i<document.theForm.elements.length; i++) { IF ELEMENT HAS AN ID ATTRIBUTE POPULATE ids array } Hi all I have a form with one or more DIV elements inside it. When I try to count form elements I get result=0? How is this possible? See the example: Code:
<html>
<head>
<script language="javascript">
function Count()
{
alert(document.frm1.elements.length);
for(i=0; i<document.frm1.elements.length; i++)
{
alert(document.frm1.elements[i].name);
}
}
</script>
</head>
<body>
<form id="frm1" name="frm1">
<div id="div1" name="div1">.</div>
</form>
<input type="button" onclick="Count();" />
</body>
</html>
If I put other element (textbox) inside the form, the count result is correct. Is DIV not an element?! How can I count one or more DIV and inner DIV's? Thanks for your help. Z. I am trying to develop a function that creates a certain number of form elements based on a certain number that a user inputs. It does not do what I want it to do (obviously). The problem lies within the TextBoxAppear() function. The function worked when I tested it by adding just text (document.getElementByID('leftcolumn').innerHTML = "<p>test function</p>" so I know for a fact whatever I added to the function is the problem. What has been added to the function and needs fixing is in BOLD Code: <!DOCTYPE html>
<html>
<head>
<meta charset = "utf-8">
<title>Exercise 4</title>
<style type = "text/css">
#leftcolumn { width: 300px; border: 1px solid red; float: left}
#rightcolumn { width: 300px; border: 1px solid red; float: left}
</style>
<script>
function start()
{
var button = document.getElementById( "submitButton" );
button.addEventListener( "click", TextBoxAppear, false );
}
function TextBoxAppear()
{
var numberOfValuesInput = document.getElementByID( 'NumberOfValuesField' );
var numberOfValues = parseFloat( numberOfValuesInput.value );
var textBoxCreation = "<form action ="http://www.deitel.com"><p>";
for ( var i = 1; i < numberOfValues; ++i )
{
textBoxCreation += "<label>Value" + i + ":<input id = 'Value" + i + "' type = 'text'></label>";
}
textBoxCreation += "<input id = "calculateButton" type = "button" value = "Calculate"></p></form>
document.getElementById('leftcolumnn').innerHTML = textBoxCreation;
}
window.addEventListener( "load", start, false );
</script>
</head>
<body>
<form action ="http://www.deitel.com">
<p><label>Number of values to be calculated:
<input id = "numberOfValuesField" type = "text"></label>
<input id = "submitButton" type = "button" value = "Submit"></p>
</form>
<div id ="leftcolumn"><p>test left column</p></div>
<div id ="rightcolumn"><p>test right column</p></div>
</body>

I wanted to know if document.getElementById works while accessing form elements. I tried doing this just for testing purposes This code doesnt work function validateForm() { var val = document.getElementById("id_login").getAttribute("value"); alert(val); return false; } but this does function validateForm() { alert(document.myForm.text_login.value ); return false; } Why doesnt document.getElementByid work with form objects.it works with all non form HTML objects.. Guys, For some reason my script only works when I have at lease two checkboxes. To simulate the problem just run it once with two html input checkbox elements -> check one checkbox and press submit -> it works -> Now remove one input checkbox field and check the remaining checkbox & submit -> Bamm doesn't work... What am I doing wrong ? Code: <html>
<head>
<script>
function Check(chk)
{
for (i=0; i < chk.length; i++) chk[i].checked=document.ListActionForm.Check_ctr.checked ;
}
function desubmit()
{
if(get_args()==false) {alert("nothing_selected");return false;}
if(labelling(true)) return false;
}
function labelling(s) {return true;}
function get_args()
{
s=chkboxa2str(document.ListActionForm['listaction[]']);
if(s)alert(s);
if(s.length<8)return false;
else return s;
}
function chkboxa2str(chkbox_a) {
var list = "";
for(var i = 0; i < chkbox_a.length; i++){ if(chkbox_a[i].checked) { list += chkbox_a[i].value + " "; } }
return list;
}
</script>
</head>
<body>
<form action="?h=1296078874" method="post" name="ListActionForm" onsubmit="return desubmit()">
<input type='checkbox' name='listaction[]' value='2010102909103530'> Testbox 1<br>

Hi all, I had posted earlier on the NaN issue. I have worked some more on my test file. Basically I want the user to select an option depending on whether he/she has Paracetamol in syrup or drops form. Once this is selected, automatically a different div for syrup or for drops should be seen depending on what the user selected earlier. After this on pushing the calculate button, the output should be appropriate depending on the strength of the solution either for drops or syrup. I have put together what I think code that should work but it stubbornly refuses to do otherwise. I have attached the relevant file. If it doesn't work, obviously there is something wrong but what it is eludes me. Any help will be appreciated greatly, Thanks, I am very new to javascript. I have a problem getting to any element from this form generated by the jsp page using struts. Please show me how to get to item[0].totalAmount for example, so that I can create a function to calculate the calculateTotal(). So far, when I do the alert, it is only valid up to document.myForm.item; the document.myForm.item[0] is invalid according to the alert. Any help is very much appreciated. function calculateTotal(){ alert(document.myForm.item); } <form name="myForm" method="post" action="/myAction.do"> <table id="display" border="1"> <tr> <th scope="col" id="totalAmount">Total Amount</th> <th scope="col" id="adjustmentAmount>Adjustment Amount</th> <th scope="col" id="newAmount">NewAmount</th> </tr> <tr> <td><input type="text" name="item[0].totalAmount" id="totalAmount" value="100" readonly="readonly"></td> <td><input type="text" name="item[0].adjustmentAmount" id="adjustmentAmount" value="" onblur="javascript:calculateTotal();" readonly="readonly"></td> <td><input type="text" name="item[0].newAmount" id="newAmount" value="" readonly="readonly"></td> </tr> <tr> <td><input type="text" name="item[1].totalAmount" id="totalAmount" value="350" readonly="readonly"></td> <td><input type="text" name="item[1].adjustmentAmount" id="adjustmentAmount" value="" onblur="javascript:calculateTotal();" readonly="readonly"></td> <td><input type="text" name="item[1].newAmount" id="newAmount" value="" readonly="readonly"></td> </tr> </table> </form> |
