I managed to add an input(text-field of login) childNode to a label(login)
<script>
let wrapperr = document.getElementById("dynamic-field");
var label1 = document.createElement("label");
label1.appendChild(document.createTextNode("login"));
wrapperr.appendChild(label1);
linebreak = document.createElement("br");
label1.appendChild(linebreak);
var input1 = document.createElement("input");
label1.insertBefore(input1, label1.children[1]).style.width = "94%";
</script>
now I want to add to that input a childNode of label(password) and to that label another childNote for the password-field.
below is my try
<script>
var label2 = document.createElement("label");
label2.appendChild(document.createTextNode("password"));
line_break.insertBefore(label2, line_break.children[1]).style.width = "94%";
var input2 = document.createElement("input");
label2.insertBefore(input2, label2.children[1]).style.width = "94%";
</script>
You can't add a child to a BR element - only to its parent. Doing so, will automatically make it the last child, unless you specifically choose otherwise.

How to set DOM element as first child?

I currently have this code in JavaScript
function addTask() {
// Declaring Variables
var item = document.getElementById("text_field").value;
var text = document.createTextNode(item);
var list_element = document.createElement("li");
var checkbox = document.createElement("input");
checkbox.setAttribute("type", "checkbox");
list_element.appendChild(checkbox);
list_element.appendChild(text);
document.getElementById("todo-list").appendChild(list_element);
}
This works fine to create a list, but the list items are added at the bottom of the html list. How do I add the new user input to the top of the html list?
I think you can place them in an array then reverse them.
this will be an example below
function addTask() {
// Declaring Variables
var item = document.getElementById("text_field").value;
var text = document.createTextNode(item);
var list_element = document.createElement("li");
var checkbox = document.createElement("input");
checkbox.setAttribute("type", "checkbox");
list_element.appendChild(checkbox);
list_element.appendChild(text);
document.getElementById("todo-list").appendChild(list_element);
}
function reverseElement(){
var reversedElement = Array.from(document.getElementById("todo-list")).reverse()
}
Use prepend instead of append.
Here is the working example:
function addTask() {
// Declaring Variables
var date = new Date;
var item = document.getElementById("text_field").value;
var list_element = document.getElementById('tasks');
var li = document.createElement("li");
li.innerText = item + '\t|\t' + date.toISOString();
list_element.prepend(li);
}
<input id="text_field" />
<button onclick="addTask()">Add</button>
<div>
<h1>Tasks</h1>
<ol id="tasks"></ol>
</div>

What do querySelectorAll and getElementsBy* methods return?

Closed 6 years ago.
Pretty Straight forward. My button is not creating the input I need after the click event. I need the fields populated where the class "household" is. I cannot edit HTML only Javascript. Any ideas?
HTML:
<ol class="household"></ol>
<div>
<button class="add">add</button>
</div>
JS:
document.getElementsByClassName("add").onclick = function() {
createinput()
};
count = 0;
function createinput() {
field_area = document.getElementsByClassName('household')
var li = document.createElement("li");
var input = document.createElement("input");
input.id = 'field' + count;
input.name = 'field' + count;
input.type = "text"; //Type of field - can be any valid input type like text,file,checkbox etc.
li.appendChild(input);
field_area.appendChild(li);
//create the removal link
var removalLink = document.createElement('a');
removalLink.onclick = function() {
this.parentNode.parentNode.removeChild(this.parentNode)
}
var removalText = document.createTextNode('Remove Field');
removalLink.appendChild(removalText);
li.appendChild(removalLink);
count++
}
document.getElementsByClassName gives you object of all child elements which have all of the given class names . You will have to attach the event on each element by iterating over the array or by using index.
Here you can use document.querySelector for your example which returns the first Element matching with the selector.
https://developer.mozilla.org/en-US/docs/Web/API/Document/querySelector
document.querySelector(".add").onclick = function() {
createinput()
};
count = 0;
function createinput() {
field_area = document.querySelector('.household')
var li = document.createElement("li");
var input = document.createElement("input");
input.id = 'field' + count;
input.name = 'field' + count;
input.type = "text"; //Type of field - can be any valid input type like text,file,checkbox etc.
li.appendChild(input);
field_area.appendChild(li);
//create the removal link
var removalLink = document.createElement('a');
removalLink.onclick = function() {
this.parentNode.parentNode.removeChild(this.parentNode)
}
var removalText = document.createTextNode('Remove Field');
removalLink.appendChild(removalText);
li.appendChild(removalLink);
count++
}
<ol class="household"></ol>
<div>
<button class="add">add</button>
</div>
It should be document.getElementsByClassName("add")[0].onclick
As Document.getElementsByClassName():
Returns an array-like object of all child elements which have all of
the given class names. When called on the document object, the
complete document is searched, including the root node. You may also
call getElementsByClassName() on any element; it will return only
elements which are descendants of the specified root element with the
given class names.
document.getElementsByClassName("add")[0].onclick = function() {
createinput()
};
count = 0;
function createinput() {
field_area = document.getElementsByClassName('household')
var li = document.createElement("li");
var input = document.createElement("input");
input.id = 'field' + count;
input.name = 'field' + count;
input.type = "text"; //Type of field - can be any valid input type like text,file,checkbox etc.
li.appendChild(input);
field_area.appendChild(li);
//create the removal link
var removalLink = document.createElement('a');
removalLink.onclick = function() {
this.parentNode.parentNode.removeChild(this.parentNode)
}
var removalText = document.createTextNode('Remove Field');
removalLink.appendChild(removalText);
li.appendChild(removalLink);
count++
}
<div>
<button class="add">add</button>
</div>
x.getElementsByClassName()
getElementByClassName returns a collection.
x.onclick
onclick is meant for single elements and cannot be directly applied to a collection. Thats why your code is not working.
If you wanted to use a collection then a loop would work as suggested by one of the other answers.
I would have a think about the approach you want to take see this answer on .getElementsByClassName().
I am a still a newbie so sorry for any mistakes. I have searched a lot and couldn't solve my problem. I dynamically created this radio input:
var radio_input = document.createElement('input');
radio_input.type = "radio";
radio_input.name = "test_input"
radio_input.value = "teeest";
radio_input.appendChild(my_form);
However I can't get the input value to show up. I get something similar to this:
(but one instead of 3)
I want to have "test" written in the left side of the input... Can someone help me?
As #RobertoLinare said in his comment, you can create a div and append the label:
var radio_input = document.createElement('input');
var label = document.createElement('label');
var div = document.createElement('div');
radio_input.type = "radio";
radio_input.name = "test_input"
radio_input.value = "teeest";
label.innerHTML = "Label";
document.getElementById("my_form").appendChild(div);
div.appendChild(label);
div.appendChild(radio_input);
<form id="my_form">
</form>
Html :
<form id="my_form"></form>
JS :
var myForm = document.getElementById("my_form");
// Clear previous contents of the container
while (myForm.hasChildNodes()) {
myForm.removeChild(myForm.lastChild);
}
var radio_input = document.createElement("input");
radio_input.type = "radio";
radio_input.name = "test_input";
radio_input.value = "teeest";
var label = document.createElement('label');
label.innerHTML = "Label Title ";
myForm.appendChild(radio_input);
myForm.appendChild(label);
I'm building a small to do list and everything worked fine so far until I included a checkbox. now when I click on the button, nothing happens and neither do I see a checkbox. There must be something wrong with the order of code-does someone know how I need to rearrange the code and WHY?
Html code:
<body>
<h1>To Do List</h1>
<p><input type="text" id="textItem"/><button id="add">Add</button></p>
<ul id="todoList">
</ul>
</body>
Javascript code:
function addItem() {
var entry = document.createElement("li");
var checkBox = document.getElementById("input");
checkBox.type = "checkbox";
var span = document.createElement("span");
span.innerText = entry;
var textItem = document.getElementById("textItem");
entry.innerText = textItem.value;
var location = document.getElementById("todoList");
entry.appendChild(checkBox);
entry.appendChild(span);
location.appendChild(entry);
}
var item = document.getElementById("add");
item.onclick = addItem;
UPDATED - I've spotted 4 issues . Follow Below :
1st : When you create the check box you should be using setAttribute method to specify input type : checkbox.setAttribute("type" , "checkbox")
2nd : Your checkbox variable should be creating an input element : var checkBox = document.createElement("input");
3rd : You should be using innerHtml instead of innerText as you are referencing a list ELEMENT stored in your entry variable : span.innerHtml = entry;
4th: Really minor but you should grab your item and attach an event to the item before your function :
var item = document.getElementById("add");
item.addEventListener("click" , addItem)
Just change your javascript to the following :
var item = document.getElementById("add");
item.addEventListener("click" , addItem)
function addItem() {
var entry = document.createElement("li");
var checkBox = document.createElement("input");
checkBox.setAttribute("type" , "checkbox");
var span = document.createElement("span");
span.innerHtml = entry;
var textItem = document.getElementById("textItem");
entry.innerText = textItem.value;
var location = document.getElementById("todoList");
entry.appendChild(checkBox);
entry.appendChild(span);
location.appendChild(entry);
}

Good Luck!
EDIT:
Currently using this javascript code, it works for the plus box but not the minus. (changed code fragment from the below.
// Create buttons for creating and removing inputs
var newAddButton = document.createElement('input');
newAddButton.id= "submit2";
newAddButton.type = "button";
newAddButton.value = " + ";
var newDelButton = document.createElement('input');
newDelButton.type = "button";
newDelButton.value = " - ";
newAddButton.id= "submit2";
I've got a javascript form, two buttons and a form is created when the plus is clicked, I was just wondering if the buttons that appear can be set to the same CSS style as the button next to the drop down lists.
So in short a css style attached to the buttons made through a javascript
HTML
<div id="mainContainer">
<div>
<select name="text[]">
<option value="t1">t1</option>
<option value="t2">t2</option>
<option value="t3">t3</option>
</select>
<input name="none" type="button" id="submit2" onClick="addNew();" value=" + ">
</div>
</div>
JAVASCRIPT
var counter = 0;
function addNew(e) {
var countAll = document.getElementsByTagName("select").length - 1;
var lastSelectBox = document.getElementsByTagName("select")[countAll];
var items = lastSelectBox.innerHTML;
// Get the main Div in which all the other divs will be added
var mainContainer = document.getElementById('mainContainer');
// Create a new div for holding text and button input elements
var newDiv = document.createElement('div');
// Create a new text input
var newText = document.createElement('select');
newText.type = "select";
newText.setAttribute("name", "text[]");
newText.innerHTML = items;
//for testing
// Create buttons for creating and removing inputs
var newAddButton = document.createElement('input');
newAddButton.type = "button";
newAddButton.value = " + ";
var newDelButton = document.createElement('input');
newDelButton.type = "button";
newDelButton.value = " - ";
// Append new text input to the newDiv
newDiv.appendChild(newText);
// Append new button inputs to the newDiv
newDiv.appendChild(newAddButton);
newDiv.appendChild(newDelButton);
// Append newDiv input to the mainContainer div
mainContainer.appendChild(newDiv);
// Add a handler to button for deleting the newDiv from the mainContainer
newAddButton.onclick = addNew;
newDelButton.onclick = function() {
mainContainer.removeChild(newDiv);
};
};
There are a number of things wrong with the fiddle.
To get your question out of the way, the CSS has an extraneous }, which causes the style for #submit3 to be ignored. Remove it.
The Javascript in the fiddle should not be wrapped in an onload handler; set it to "No wrap - in head" or "No wrap - in body". Otherwise clicking the button won't work.
The newly created buttons all have the same IDS. This is a no-no. Make the Javascript remember how many buttons there are and give them a unique ID based on the count. (Something like ++numberofbuttons; id = 'submit'+(numberofbuttons*2); for the one, and same plus +1 for the other.)
Oh, and your fiddle differs from the example code in the question. Don't do that.
