Append Data to DIV

How to append data to

We can append data to an element using JavaScript by using the .innerHTML property to add content to the element. This can be done by using the += operator to add the new content to the existing content within the . We can also use the .appendChild() method to add a new child element to the .

is a block-level element that is used to create a division or section in an HTML document. The element is usually used to group elements together, such as paragraphs, headings, or images. The element can also be used to style a section of the document, such as adding a background color or border.

Approach

To append data to a div element using JavaScript, you would first need to select the element using a selector, then use the append() or appendChild() method to append data to the selected element.

Here is an example of how you would append a paragraph element to a div element −

var div = document.querySelector('div'); var p = document.createElement('p'); p.textContent = 'This is some data that will be appended to the div element'; div.appendChild(p);

Example

Assuming you have a div with an id of “content” −

Element: append() method

The Element.append() method inserts a set of Node objects or string objects after the last child of the Element . String objects are inserted as equivalent Text nodes.

• Element.append() allows you to also append string objects, whereas Node.appendChild() only accepts Node objects.
• Element.append() has no return value, whereas Node.appendChild() returns the appended Node object.
• Element.append() can append several nodes and strings, whereas Node.appendChild() can only append one node.

Syntax

append(param1) append(param1, param2) append(param1, param2, /* … ,*/ paramN) 

Parameters

A set of Node or string objects to insert.

Return value

Exceptions

Thrown when the node cannot be inserted at the specified point in the hierarchy.

Examples

Appending an element

let div = document.createElement("div"); let p = document.createElement("p"); div.append(p); console.log(div.childNodes); // NodeList [ 
] 

Appending text

let div = document.createElement("div"); div.append("Some text"); console.log(div.textContent); // "Some text" 

Appending an element and text

let div = document.createElement("div"); let p = document.createElement("p"); div.append("Some text", p); console.log(div.childNodes); // NodeList [ #text "Some text", 
] 

The append method is unscopable

The append() method is not scoped into the with statement. See Symbol.unscopables for more information.

let div = document.createElement("div"); with (div)  append("foo"); > // ReferenceError: append is not defined

Adding content to a div from javascript

I would like to load a script that contains the content of a div on my html page. I know this is possible, but I am struggling to understand how to do it. Here is my html:

What would script.js have to be for the html page to display something? I was thinking something like this (I know it’s incorrect, I’m a beginner at javascript.

function showText() < $("#helloWorld").html("
Hello World!
 ") $("#helloWorld").show(); > showText() 

4 Answers 4

$("#helloWorld").html(" 
Hello World!
 ") $("#helloWorld").show(); 

and you don’t need $(«#helloWorld»).show(); .

function showText() < document.getElementById("helloWorld").innerHTML="
Hello World!
 "; > showText() 

But remember to call showText() after the loading of the div in the DOM! (For example, call it just before tag).

function showText() < document.getElementById("helloWorld").innerHTML="
Hello World!
 "; > 

I think it does nothing (I assume) becaue your script tag is before the div itself. If you’re using JQuery, you should put your initial code into the ready function, in your case:

When your script loads, the HTML element » #helloWorld » still doesn’t exist.

function showText() < $("#helloWorld").html("
Hello World!
 ") $("#helloWorld").show(); > $(document).ready(function() < showText(); >); 

the syntax you are trying to use requires JQuery. You can download the latest JQuery library here http://jquery.com/

Then you can use the following in order to add text to your div:

$(document).ready(function() < var showText = function()< $("#helloWorld").html("
Hello World!
 ") $("#helloWorld").show(); >; showText(); >); 

Edited: I have added in the $ character at the start of (document), also, it is not necessary to have the .show() function on your div as it is already visible. If you do however set that div’s display to none, you should use .show() to display the div.

Javascript append data in div

# Append text to an Element (DIV, SPAN, P) in JavaScript

To append text to an element:

1. Use the document.createTextNode() method to create a text node.
2. Use the appendChild() method to append the text node to the element.
3. The appendChild method will add the text node to the end of the element’s list of children.

Here is the HTML for the examples.

Copied! 
DOCTYPE html> html lang="en"> head> meta charset="UTF-8" /> title>bobbyhadz.comtitle> head> body> div id="box"> bobby span style="background-color: salmon">hadzspan> div> script src="index.js"> script> body> html> 

And here is the related JavaScript code.

Copied! 
// ✅ Append text to element const box = document.getElementById('box'); const text = document.createTextNode(' tutorial'); box.appendChild(text); 

We selected the element we want to append text to using the document.getElementById() method.

The next step is to create a text node using the document.createTextNode method.

The method takes a string and creates a text node from it.

This is especially useful when taking user-provided data because the method escapes HTML characters and prevents XSS attacks.

The last step is to use the Node.appendChild method to append the text node to the end of the element’s children.

This approach can be used to append text to any element, e.g. div , span , paragraph, etc.

Alternatively, you can use the insertAdjacentText method.

# Append text to an element (DIV, SPAN, P) using insertAdjacentText()

You can also use the insertAdjacentText method.

The method takes a position and a string as parameters and inserts a new text node at the provided position relative to the element it was called on.

Copied! 
const box = document.getElementById('box'); box.insertAdjacentText('beforeend', ' new text'); 

The insertAdjacentText method takes the following 2 parameters:

1. position — the position relative to the element where the text should be inserted. Can be one of the following 4:

• beforebegin — before the element itself.
• afterbegin — just inside the element, before its first child.
• beforeend — just inside the element, after its last child.
• afterend — after the element itself.

1. data — the string from which to create a new text node to insert at the given position.

You can use the insertAdjacent method to append text to an element of any type, e.g. div , span , paragraph.

Which approach you pick is a matter of personal preference. I’d go with the insertAdjacentText method as it is more concise and direct.

# Append HTML to an element (DIV, SPAN, P) in JavaScript

If you need to append HTML to an element and not just text, use the insertAdjacentHTML method.

Copied! 
const box = document.getElementById('box'); box.insertAdjacentHTML( 'beforeend', ' New html', ); 

The insertAdjacentHTML() method takes the following 2 parameters:

• position — the position relative to the element where the HTML should be inserted. Can be one of the following:
  • beforebegin — before the element itself.
  • afterbegin — just inside the element, before its first child.
  • beforeend — just inside the element, after its last child.
  • afterend — after the element itself.

  It should be noted that you shouldn’t append HTML that is from user-generated input without escaping it.

  In the example, we inserted text just inside the div element, after its last child, but you can change the first argument depending on your use case.

  I wrote a book in which I share everything I know about how to become a better, more efficient programmer.
