Javascript?:How to dynamically add text inputs/form fields to a HTML form?

Question

I am building a web form where there is a list of inputs. So far, so good.

However, how can I add a link/button to add say another 5 fields to the list. eg:

<input>
<input>
<input>
<input>

<a href="" onclick="">Add 10 more fields</a>

I have looked through many similar q's on this site, however none seem to describe how to add multiple fields.

Thanks for any help,

Harley

EDIT: Thanks all for help, looks like jquery append is the way to go. However I appreciate the alternative that does not use jquery.

  $("#anyDiv").html('<input id="id1"/>');

....

 $("#anyDiv").append('<input id="id2"/>');

@harley - I just discovered today that $("body").append(someContent) does not work in IE7 while $(someContent).appendTo("body") does work. Quirky I know, but it reminded about this question and thought I'd come back and update it. – hardba11 Aug 22 '12 at 20:45

Here's a js fiddle showing the example of adding 10 inputs using jQuery's append() function. I suggest only doing one addition per click as in user1301840's example though.

HTML

<div id="inputList"></div>
<input type="button" value="Add 10 Inputs" id="addInputs" />

Javascript

$('#addInputs').click(function() {
    for (i = 0; i < 10; i++) {
        $('#inputList').append('<input type="text" />');

    }
});

Sorry, another question- how could I make them into a list so they all sit on the left? – harley_woop Jul 13 '12 at 16:45
@harley: You could use `display: block` for the `input`s. Then each would have its own line. – FlyingMolga Jul 13 '12 at 18:20
Pay attention when copying code, I've gone crazy because of a invisible character at the end of the block. – Angelo Tricarico Sep 12 '14 at 15:34

While you already have answers, I thought I'd try and provide a non-jQuery solution:

function addInput(insertAt, formEl, num, inputType, defaultVal) {
    console.log(formEl);
    if (!formEl) {
        return false;
    }
    else {
        num = num ? num : 5;
        var fieldset = document.createElement('fieldset'),
            newInput;
        for (var i = 0; i < num; i++) {
            newInput = document.createElement('input');
            newInput.value = defaultVal || '';
            newInput.type = inputType || 'text';
            fieldset.appendChild(newInput);
        }
        formEl.insertBefore(fieldset, insertAt);
    }
}

var formEl = document.getElementById('theForm'),
    aElem = document.getElementById('aElement');

if (window.addEventListener) {
    // up to date browsers
    aElement.addEventListener('click', function() {
        addInput(this, formEl, 10);
    }, false);
} else if (window.attachEvent) {
    // legacy IE, <9
    aElement.attachEvent('onclick', function() {
        addInput(this, formEl);
    });
}

JS Fiddle demo.

I don't have IE to test, but the above should work with IE < 9 using the attachEvent fall-back, and >= 9, I think, implements the standard addEventListener().

I think I'm going to use the jquery append. I'll use your solution I I ever have to do this again with using the library! — harley_woop, Jul 13 '12 at 18:06

try use the JQuery .append() function

$("a").click(function(e){
 $("form").append("<input />");
})

Yep, jquery is the way to go here.

$("<input type='text'>").appendTo("#someContainer");

Good luck.

The following example add input box at click a link:

<div id="start">
    <input/><br/><br/>
</div> 
<a href="#" id="box">Add more fields</a>

$("#box").click(function(){
    var add="";
    add+='<input/>'+'<br/>'+'</br/>';
    $("#start").append(add);
});

<script type='text/javascript'>
    var counter = 1;
    var limit = 3;
    function addInput(divName) {

        var newdiv = document.createElement('div');
        newdiv.innerHTML = "<br><input type='text' name='myInputs" + counter + "'> <input type='text' name='myInputs" + counter + "'> <select><option value='88888'>888888888</option></select>";
        document.getElementById(divName).appendChild(newdiv);
        counter++;
    }
</script>

<form method="POST">
    <div id="dynamicInput">

        <input type="button" value="Add another text input" onclick="addInput('dynamicInput');">
</form>

Adding some explanation in English would be great – Manos Nikolaidis Feb 24 '16 at 17:22 — Manos Nikolaidis, Feb 24 '16 at 17:22
