Getting Data out of a container

I wrote a function that creates new Input fields based on the number of input fields needed. That code is below.
for (i=0;i<number;i++){
container.appendChild(document.createTextNode("Guest " + (i+1)));
var input = document.createElement("input");
input.id = "Guest" + i;
container.appendChild(input);
container.appendChild(document.createElement("br"));
console.log(i.value);
It creates a new Id for each input field. In the function below,depending on the number you set for i, the function creates a generated message.
function sendInput ()
{
var guestNames = document.getElementById("Guest").value
var personName = document.getElementById("people").value;
var eventType = document.getElementById("event").value;
var date = document.getElementById("date").value;
var output = "Dear " + guestNames + " You have been invited to " + personName + "'s " + eventType + " on " + date + " Thank you for coming!!";
document.getElementById('output').innerHTML = output.repeat(i);
}
The problem is it is not collecting the data for guestNames. I am pretty new to JS but have searched and cannot find a solution to my problem. Any feedback wouls be helpful.

IDs are difficult to work with in a dynamic environment, classes are generally the simplest solution. This code will convert your inputs to have classes, then loop through them and collect the names.
So change:
input.id = "Guest" + i;
to
input.setAttribute("class","guest");
And change
var guestNames = document.getElementById("Guest").value
to:
var guests = document.querySelectorAll(".guest");
var guestNames = [];
guests.forEach(function(el){
guestNames.push(el.value);
});
guestNames = guestNames.join(",");
If you are wanting a message for EACH guest, then you would use the below function:
function sendInput ()
{
var personName = document.getElementById("people").value;
var eventType = document.getElementById("event").value;
var date = document.getElementById("date").value;
var guests = document.querySelectorAll(".guest");
var guestNames = [];
document.getElementById('output').innerHTML = "";
guests.forEach(function(el){
document.getElementById('output').innerHTML += "Dear " + el.value + " You have been invited to " + personName + "'s " + eventType + " on " + date + " Thank you for coming!!";
});
}

You try to get node by id var guestNames = document.getElementById("Guest").value
But all nodes have a different id, like a Guest0,Guest1 etc. I am trying to write my own code, but your snippet isn't full. I hope I helped you.

As far as I can see, when you try to fetch the guest name
var guestNames = document.getElementById("Guest").value
you won't get any element for two reasons because there's no element with id "Guest". In fact you generate them in the form "GuestN"
`input.id = "Guest" + i;`
You probably want to add a parameter i to sendInput () function, so that internally you can concatenate it to Guest as you did above and get the correct element with getElementById().

Your code is incomplete (as far as I can tell).
You do not specify the following elements anywhere:
'container', 'guest', 'people', 'event', 'data' or 'output'
I assume they should be defined somewhere in the HTML section (not provided)
To be able to create the variable displays, you need to define the 'container' you wish to initialize it before it is used in the for() loop that follows.
Example: var container = document.getElementById('container');
Within the loop, console.log(i.value) is invalid as i is not an element that has been assigne a value to display. It is a counter of the for() loop.
The function of sendInput(), I assume, is to collect the information from the user for each "Guest#" created by the first loop of your code. However you try to collect from "Guest" which has not been defined. For a number of 5, the collections should be for "Guest1", "Guest2", "Guest3", "Guest4", "Guest5". "Guest" only can not be found anywhere in your loop creation. Same goes for 'people, 'event' and 'date' which are referenced for value collection, but there are no elements named as such.
Not exactly sure why you are mixing DOM creation techniques (???).
You create the number of element for the guest, but then output the results with .innerHTML. You should use the DOM creation method, but I have used your code as you indicated you are a beginner.
Here is some (partially) corrected code that you can continue on with.

function init() {
var number = 5;
var container = document.getElementById('container');
for (i=0;i<number;i++) {
var value = "Guest " + (i+1)+' ';
container.appendChild(document.createTextNode(value));
var input = document.createElement("input");
input.id = "Guest" + i;
input.value = value;
container.appendChild(input);
container.appendChild(document.createElement("br"));
console.log(i); // .value);
}

How to apply style to selected text in CKEditor using JavaScript

I want to apply heading style (h1) to the selected text in CKEditor using JavaScript.
Here is my function:
function applyStyle()
{
var selection = CKEDITOR.instances.editor1.getSelection();
if(selection.getType() == 2) //where 2 will be Text type
{
var style = new CKEDITOR.style({element: 'h1'});
selection.applyStyle(style);
style.checkActive(editor1.elementPath(), editor1);
}
else
{
alert('Select text to apply');
}
}
But I can't get the style applied on the selected text,
Kindly someone solve this
Thanks

Its a cumbersome, but I found the solution for this ,see below
function applystyle(tagName)
{
var selection = CKEDITOR.instances.editor1.getSelection().getNative();
var oEditor = CKEDITOR.instances.editor1;
var openTag = "<" + tagName + ">";
var closeTag = "</" + tagName + ">";
var html = openTag + selection + closeTag;
var newElement = CKEDITOR.dom.element.createFromHtml( html, oEditor.document );
oEditor.insertElement( newElement );
}
I found the above code working well for me,
Thanks

Changing the content of all <pre> tags using JavaScript

I want to know how I change all the pre tags inside a document...
I'm using this:
var preContent = document.getElementById('code').innerHTML;
but this only changes the content of 1 pre tag... the one with the ID 'code'.
If you can show me how i can change all the pre tags using JavaScript I appreciate
Here's all the code:
window.onload = function () {
var preContent = document.getElementById('code').innerHTML;
var codeLine = new Array();
var newContent = '<table width="100%" border="1" '
+ 'cellpadding="0" cellspacing="0" >';
codeLine = preContent.split('\n');
for (var i = 0; i < codeLine.length; i++) {
newContent = newContent + '<tr><td class="codeTab1" >'
+ i.toString() + '</td><td class="codeTab2">'
+ codeLine[i] + '</td></tr>';
}
newContent = newContent + '</table>';
document.getElementById('code').innerHTML = newContent;
}
PS: This is to make a look like a normal compiler with numbers before the line
PPS: Each pre tag will have a different content and I want the same script to change it (if possible).

You can use getElementsByTagName:
var preElements = document.getElementsByTagName('pre');
for(var i = 0; i < preElements.length; ++ i)
{
var element = preElements[i];
/* modify element.innerHTML here */
}

First problem in you code . No two elements in a document can have same id .
So you can change it easily with jquery . look at the code .
$('pre').html("what ever text you want to show ");
Or with javascript you can do like this :
var x = document.getElementsByTagName('pre');
for(var i = 0; i < x.length; ++ i)
{
x.innerHTML = "what ever text you want to show";
}

Change name values with JavaScript

Been at this for a long time, and it seems so simple but I cannot get it to do what I want.
Each book has a 'getOrRequest' value that is selected using radio buttons. Every time a div is duplicated, the name value needs to be changed so that a book has its own getOrRequest value. I've finally got the duplicating down, but now renaming the correct inputs isn't cooperating.
What's really bugging me is that it works, but it's not changing the name values that I'm trying to grab. It has something to do with what parts of the array are being changed, but I can't get the values that I want, namely the last two getOrRequest names.
A working example of what I'm struggling with here.
My JS function:
function addAnotherPost(){
var bookInfo = document.getElementById('bookInformation');
var copyDiv = document.getElementById('addListing').cloneNode(true);
copyDiv.id = 'addListing' + idNumber;
bookInfo.appendChild(copyDiv);
var divID = 'addListing' + idNumber;
var newDiv = document.getElementById(divID);
var postType = document.getElementsByName("getOrRequest[]");
alert(postType[0].name + postType[1].name + postType[2].name + postType[3].name);
for(var i = 2; i < postType.length; i++){
postType[i].name = 'getOrRequest' + idNumber + '[]';
}
alert("got this far" + postType.length);
idNumber++;
}
The relevant chunk of HTML:
<div id='addListing'>
<table class='aListing'>
<tr>
<td>
<label>
<input type='radio' name='getOrRequest[]' value='1' />
Request</label>
<label>
<input type='radio' name='getOrRequest[]' value='0' />
Offer</label>
</td>
[...]
</table>
</div>

You are getting an object list for a specific name identifier:
var postType = document.getElementsByName("getOrRequest[]");
so postType is changing once you've renamed an element (Yes man that thing is inteligent)
console.log(postType.length); // = 4
postType[i].name = 'getOrRequest' + idNumber + '[]';
console.log(postType.length); // = 3
so basically the for loops changes because postType.length changes.
I guess what you want to do is something like:
postType[0].name = 'getOrRequest' + idNumber + '[]'; //ref changed.
postType[0].name = 'getOrRequest' + idNumber + '[]';
however thats bad style anyways you should clone from a marked source and rename by name before you append to something, like so ( http://jsfiddle.net/bHLZA/2/ ):
var bookInfo = document.getElementById('bookInformation');
var copyDiv = document.getElementById('addListing').cloneNode(true);
copyDiv.id = 'addListing' + idNumber;
postType = copyDiv.getElementsByTagName('input');
postType[0].name = 'getOrRequest' + idNumber + '[]';
postType[1].name = 'getOrRequest' + idNumber + '[]';
bookInfo.appendChild(copyDiv);

How to dynamically assign an id to an image

var intFields = 0;
var maxFields = 10;
function addElement() {
"use strict";
var i, intVal, contentID, newTBDiv, message = null;
intVal = document.getElementById('add').value;
contentID = document.getElementById('content');
message = document.getElementById('message');
if (intFields !== 0) {
for (i = 1; i <= intFields; i++) {
contentID.removeChild(document.getElementById('strText' + i));
}
intFields = 0;
}
if (intVal <= maxFields) {
for (i = 1; i <= intVal; i++) {
intFields = i;
newTBDiv = document.createElement('div');
newTBDiv.setAttribute('id', 'strText' + intFields);
newTBDiv.innerHTML = "<input placeholder='recipient" + intFields + "#email.com' type='text' name='" + intFields + "'/><a href='javascript:removeElement();'><img id='strImg + " + intFields + "' src='images/minus.png' alt='Add A Field'/></a><input type='text' value='" + newTBDiv.id + "'/>";
contentID.appendChild(newTBDiv);
message.innerHTML = "Successfully added " + intFields + " fields.";
}
} else {
for (i = 1; i <= maxFields; i++) {
intFields = i;
newTBDiv = document.createElement('div');
newTBDiv.setAttribute('id', 'strText' + intFields);
newTBDiv.innerHTML = "<input placeholder='recipient" + intFields + "#email.com' type='text' name='" + intFields + "'/><a href='javascript:removeElement();'><img id='strImg + " + intFields + "' src='images/minus.png' alt='Add A Field'/></a><input type='text' value='" + newTBDiv.id + "'/>";
contentID.appendChild(newTBDiv);
message.innerHTML = "Unable to create more than 10 receipient fields!";
}
}
}
My script here dynamically adds up to 10 fields where users will be able to enter an email address and to the right of the text box i add an image of a minus sign that calls another script. I'm having trouble working out how to assign and keep track of the minus signs. I need to be able to have the minus sign script's recognize the text box it is by and remove it. I can write the remove script easily enough but I'm unsure of how to tell the image which text box to remove. Any help, suggestions, or comments are greatly appreciated.
Thanks,
Nick S.

You can add a class to the field called minus and then check through like that. I would suggest using jquery for this.
To add the class
$("#element").addClass("minus");
To remove all elements with that class
$("body input").each(function (i) {
if($(this).attr("class") == "minus"){
$(this).remove();
}
});

The two best options, imo, would be 1) DOM-traversal, or 2) manipulating ID fragments.
Under the first way, you would pass a reference to the element where the event takes place (the minus sign) and then navigate the DOM from there to the get the appropriate text box (in jQuery you could use $(this).prev(), for example).
Under the second way, you would assign a prefix or a suffix to the ID of the triggering element (the minus sign), and the same prefix or suffix to the target element (the text box). You can then (again) generate the appropriate ID for your target element by simple string manipulation of the ID from the triggering element.
Is that sufficient to get you started?

Try adding a class to the field and the same class to the minus sign.
So add this right after the setAttribute id,
newTBDiv.setAttribute('class', 'field' + intFields);
then just remove any elements that have that class.
