I want to be able to add multiple rows to a div and also removing them. I have a '+' button at the top of the page which is for adding content. Then to the right of every row there is a '-' button that's for removing that very row. I just can't figure out the javascript code in this example.

This is my basic HTML structure:

<input type="button" value="+" onclick="addRow()">

<div id="content">

</div>

This is what I want to add inside the content div:

<input type="text" name="name" value="" />
<input type="text" name="value" value="" />
<label><input type="checkbox" name="check" value="1" />Checked?</label>
<input type="button" value="-" onclick="removeRow()">

Another solution is to use getDocumentById and insertAdjacentHTML.

Code:

function addRow() {

 const  div = document.getElementById('content');

 div.insertAdjacentHTML('afterbegin', 'PUT_HTML_HERE');

}

Check here, for more details: Element.insertAdjacentHTML()

Please explain your code a bit for the questioner. :)

@Aezaz Desai 2020-05-19 11:28:33

In this code we can easily ADD and REMOVE specific Textbox.

@Austin Brunkhorst 2013-07-15 09:29:11

You can do something like this.

function addRow() {
  const div = document.createElement('div');

  div.className = 'row';

  div.innerHTML = `
    <input type="text" name="name" value="" />
    <input type="text" name="value" value="" />
    <label> 
      <input type="checkbox" name="check" value="1" /> Checked? 
    </label>
    <input type="button" value="-" onclick="removeRow(this)" />
  `;

  document.getElementById('content').appendChild(div);
}

function removeRow(input) {
  document.getElementById('content').removeChild(input.parentNode);
}

I want to be able to add multiple rows. My question was a bit unclear so I edited it.

@Austin Brunkhorst 2013-07-15 09:38:33

This supports multiple rows.

@Daniel Tovesson 2013-07-15 09:43:53

Oh, that's right. Just made a error trying your code. It's working now. Cheers!

@Daniel Tovesson 2013-07-15 10:05:38

Although, it's not working when wrapping the inputs in a div like <div class="options_part"></div>

@Austin Brunkhorst 2013-07-15 10:07:47

What does javascript look like? Note that you have to put a back slash at the end of each line when setting the innerHTML or else you'll get a syntax error.

@Daniel Tovesson 2013-07-15 10:19:09

Posting a shorted code-snippet. div.innerHTML = '<div class="options_part"><input type="button" value="-" onclick="removeRow(this)"></div>'; And just by removing the div it's working again.

@Austin Brunkhorst 2013-07-15 10:29:02

Oh got ya. You have to remove a child from the parent, so change input.parentNode to input.parentNode.parentNode in removeRow(). A reminder that if you add any more parents to the remove buttons you'll have to change removeRow accordingly like I just did.

@Hoffmann 2018-08-01 12:45:19

To my most biggest surprise I present to you a DOM method I've never used before googeling this question and finding ancient insertAdjacentHTML on MDN (see CanIUse?insertAdjacentHTML for a pretty green compatibility table).

So using it you would write

function addRow () {
  document.querySelector('#content').insertAdjacentHTML(
    'afterbegin',
    `<div class="row">
      <input type="text" name="name" value="" />
      <input type="text" name="value" value="" />
      <label><input type="checkbox" name="check" value="1" />Checked?</label>
      <input type="button" value="-" onclick="removeRow(this)">
    </div>`      
  )
}

function removeRow (input) {
  input.parentNode.remove()
}
<input type="button" value="+" onclick="addRow()">

<div id="content">
</div>

@Arun 2013-07-15 09:30:09

You can use this function to add an child to a DOM element.

function addElement(parentId, elementTag, elementId, html) 

 {


// Adds an element to the document


    var p = document.getElementById(parentId);
    var newElement = document.createElement(elementTag);
    newElement.setAttribute('id', elementId);
    newElement.innerHTML = html;
    p.appendChild(newElement);
}



function removeElement(elementId) 

{

    // Removes an element from the document
    var element = document.getElementById(elementId);
    element.parentNode.removeChild(element);
}

@user2503896 2015-03-06 10:27:16

To remove node you can try this solution it helped me.

var rslt = (nodee=document.getElementById(id)).parentNode.removeChild(nodee);

@Aarif Qureshi 2013-07-15 09:33:46

please try following to generate

 function addRow()
    {
        var e1 = document.createElement("input");
        e1.type = "text";
        e1.name = "name1";

        var cont = document.getElementById("content")
        cont.appendChild(e1);

    }

@dashme 2013-07-15 09:29:09

make a class for that button lets say :

`<input type="button" value="+" class="b1" onclick="addRow()">`

your js should look like this :

$(document).ready(function(){
  $('.b1').click(function(){
      $('div').append('<input type="text"..etc ');
  });
});
