copy form data to clipboard

So I have a list of items, on html page, in fact in form, something like this:
ITEM 1 - ID - "checkbox" "number box"
ITEM 2 - ID - "checkbox" "number box"
I have around 400 items like this, and I found a code to copy selected items (where checkbox is selected) to clipboard and paste them where I want. But I can't make it work with quantity. So basicaly what I would like to achieve is to copy selected items with quantity to clipboard.
Can someone please help me about this problem?
<input type="button" id="prikaz" value="show" onclick="displayMaterial();" /> button for the script
<form id="myFrm" name="myFrm"> - form id
<div id="materialValues"></div> - this shows the selected item, where you can copy it
<ul id="myUL"> - ignore this this is just how i made a list
<li><span class="item"><div class=""><table><tr> <td> ARC 4012718 P2-HD-RXR-SA </td> <td> 160771 </td> <td> <input type="checkbox" id=" 160771 " name=" 160771 " value=" 160771 | ARC 4012718 P2-HD-RXR-SA "> </td> </tr></table></div></span></li>
this is just one item from my list
</ul>
and the code: (this is not my code, i found it somewhere and it works for this purpose, but I woud like to add quantity as well, but I don't have enaught knowledge to place part of the script that would handle that, somwhere around tha IF selected part.
<script type="text/javascript">
function displayMaterial()
{
var str = '';
var elem = document.getElementById('myFrm').elements;
for(var i = 0; i < elem.length; i++)
{
if(elem[i].checked)
str += elem[i].value +"<br>";
}
document.getElementById('materialValues').innerHTML = str;
}
</script>

How do I repeat the piece of html code 10 times by clicking on the same button using JS/Jquery?

I want to be able to display the same piece of html code 10 times under the div called: <div id="add_remove_product_name"> By clicking on the button called: <button id="add_another_product_name">. I think I need some kind of a for loop for the job but are not sure. Any suggestion will be helpful, thanks.
My HTML code:
<div id="product_name">
<input id="skriv_produktnavn" placeholder="Skriv Produktnavn her" required></label>
<button id="add_another_product_name">Tilføj endnu et produktnavn</button>
<div id="add_remove_product_name">
<input id="added_product_name" placeholder="Skriv Produktnavn her" required></label>
<button id="remove_product_name">X</button>
</div>

Use a for loop to concatenate 10 copies of the HTML code. Then use .after() to put this after the DIV.
$("#add_another_product_name").click(function() {
var html = '';
for (var i = 0; i < 10; i++) {
html += 'html code that you want to repeat';
}
$("#add_remove_product_name").after(html);
}

You can use jQuery clone() however when cloning an element all the attributes will be the same. Fo example they will all have the same id attribute which will cause problems and it is not valid html
So in order to do the clone correctly you have fix the cloned element
DEMO: http://jsfiddle.net/rpyt445e/
var $tpl = $('#product_name').clone();
var num = 0
$('#clone').click(function () {
num++;
var $cloned = $tpl.clone();
$cloned.attr('id', $tpl.attr('id') + '_' + num);
$(':not([id=""])', $cloned).each(function(){
$(this).attr('id', $(this).attr('id') + '_'+num);
});
$cloned.appendTo('#wrapper');
});
HTML:
<div id="wrapper">
<div id="product_name">
<input id="skriv_produktnavn" placeholder="Skriv Produktnavn her" required />
<button id="add_another_product_name">Tilføj endnu et produktnavn</button>
<div id="add_remove_product_name">
<input id="added_product_name" placeholder="Skriv Produktnavn her" required />
<button id="remove_product_name">X</button>
</div>
</div>
</div>
<button id="clone">Clone</button>

A technique for adding the additional elements without having to create ugly strings of html in the JavaScript is to start with one hidden set of the elements in the html. At page load time, you remove that set, but keep a reference to it. Then when you want to add a set to the page, you clone the set you removed. All of this is easier if you add a container div around the additional inputs.
You also need to make sure id attribute values are unique. In the case of the remove buttons, you can replace the id with a class. As for the input id values, if you really need them, you can add an index value to them.
Since the remove buttons are dynamically added, I suggest using event delegation when binding the click-handler.
HTML:
<div id="product_name">
<input id="skriv_produktnavn" placeholder="Skriv Produktnavn her" required="required"/>
<button id="add_another_product_name">Tilføj endnu et produktnavn</button>
<div id="additional_product_names">
<div class="add_remove_product_name" style="display: none;">
<input id="added_product_name" placeholder="Skriv Produktnavn her" required="required"/>
<button class="remove_product_name">X</button>
</div>
</div>
</div>
JavaScript:
$(function() {
var MAX = 10;
var $addBtn = $('#add_another_product_name'),
$additionalContainer = $('#additional_product_names');
$TEMPLATE = $additionalContainer.children(':first').remove();
function update() {
var $additonalDivs = $additionalContainer.children();
// Enable/disable the add button.
$addBtn.prop('disabled', $additonalDivs.length >= MAX);
// Re-index the "id" attributes.
$additonalDivs.find('input').attr('id', function(i) {
return 'added_product_name[' + i + ']';
});
}
$addBtn.click(function() {
$TEMPLATE.clone().appendTo($additionalContainer).show();
update();
});
$('#product_name').on('click', '.remove_product_name', function() {
$(this).closest('.add_remove_product_name').remove();
update();
});
});

Increment of counter on dynamic addition of rows

I'm trying to add the rows dynamically plus auto-increment of a counter.I want to start with 1 then 2 then 3 and so on . I have added my code on plunker ,in which every time the max value is getting in first column like 4 then 1,1,2,3.Where am i going wrong ?i Want it to be 1,2,3,4.
Here is the plunker link http://plnkr.co/edit/GuDbJ3SHOPvWkHfNfd8E?p=preview
var _counter = 0;
function Add() {
_counter++;
var oClone = document.getElementById("template").cloneNode(true);
oClone.id += (_counter + "");
document.getElementById("placeholder1").appendChild(oClone);
document.getElementById("myVal").value=_counter;
}
<div id="placeholder1">
<div id="template">
<div>
Value:<input type="text" id="myVal" placeholder="1">
Quantity:<input type="text" placeholder="Qty">
<input type="button" onClick="Add()" value="Click! ">
</div>
</div>

I think it is because you have multiple divs with the id="myVal". The id attribute should be unique on the page. If not, your page will still load, but you may have unexpected behavior.
You are changing the id of the template div, but not the myVal div.

I assume you are looking for something like this:
var _counter = 0;
function Add() {
_counter++;
var oClone = document.getElementById("template").cloneNode(true);
oClone.id += (_counter + "");
document.getElementById("placeholder1").appendChild(oClone);
oClone.getElementsByClassName("myVal")[0].value = _counter;
}
<div id="placeholder1">
<div id="template">
<div>
Value:
<input type="text" class="myVal" placeholder="1">Quantity:
<input type="text" placeholder="Qty">
<input type="button" onClick="Add()" value="Click! ">
</div>
</div>
</div>
In your original you are cloning your template with the same id for the input. So when you do document.getElementById("myVal").value=_counter;, you only get the first input. I changed it to use class instead and get the input with the appropriate class that is a child of the cloned node.

Javascript Inserting a clone ordering issue

I am trying to clone and insert items in order in JS, I can clone and add elements but the order seems to be incorrect, I am trying to assign a value to the radio buttons so I can tie the radio buttons to the text fields as seen below:
<div id='1'>
<div class="template">
<div>
<label class="right inline">Response:</label>
</div>
<div>
<input type="text" name="responseText[]" value="" maxlength="400" />
</div>
<div>
<input type="checkbox" name="responsCheck[]" value="0" />
</div>
</div>
<div>
<input type="button" name="addNewRow" value="Add Row" />
</div>
</div>
JS:
var $counter = 0;
var $template = $('.template');
$('input[type=button]').click(function() {
var $elem = $template.clone();
$elem.find("input:text").val("");
$copy.find("input:radio").val($counter);
$elem.insertAfter($template);
});
If I add three rows for example, the Values of the checkbuttons are in the following order:
0
2
1
I need the Values to be in the following order:
0
1
2
anybody got any ideas? I think it must be the way I am inserting the clone? When I am using radio buttons this line seems to work:
$elem.insertAfter($('#1 .clone').last());
but when using checkboxes it doesn't seem to work any ideas?

To me problem looks like that on adding second entry $template still points to the first entry.
I would try by moving $template initialization inside click handler and changing it like below.
var $counter = 0;
$('input[type=button]').click(function() {
var $template = $('.template:last');
});
This way $template should point to the last template inserted and it should work as expected.

Maybe you need to use:
$("#1").append($elem);
instead
$elem.insertAfter($template);
Or select the last every time.
var $template = $('.template').last();

Put them into a js array and sort them by val:
function SortByValue(elem1, elem2){
var e1 = Number($(elem1).val());
var e2 = Number($(elem2).val());
return ((e1 < e2) ? -1 : ((e1 > e2) ? 1 : 0));
}
var sortedValues = $.makeArray($(jQSelector)).sort(SortByValue);

Show/hide forms using buttons and JavaScript

I need to show a form using a button, and hide it when the user presses another button, because the other button shows another form. I did a similar thing with a select box, but I can't figure out how to do this.

Use the following code fragment to hide the form on button click.
document.getElementById("your form id").style.display="none";
And the following code to display it:
document.getElementById("your form id").style.display="block";
Or you can use the same function for both purposes:
function asd(a)
{
if(a==1)
document.getElementById("asd").style.display="none";
else
document.getElementById("asd").style.display="block";
}
And the HTML:
<form id="asd">form </form>
<button onclick="asd(1)">Hide</button>
<button onclick="asd(2)">Show</button>

There's something I bet you already heard about this! It's called jQuery.
$("#button1").click(function() {
$("#form1").show();
};
It's really easy and you can use CSS-like selectors and you can add animations. It's really easy to learn.

If you have a container and two sub containers, you can do like this
jQuery
$("#previousbutton").click(function() {
$("#form_sub_container1").show();
$("#form_sub_container2").hide(); })
$("#nextbutton").click(function() {
$("#form_container").find(":hidden").show().next();
$("#form_sub_container1").hide();
})
HTML
<div id="form_container">
<div id="form_sub_container1" style="display: block;">
</div>
<div id="form_sub_container2" style="display: none;">
</div>
</div>

There's the global attribute called hidden. But I'm green to all this and maybe there was a reason it wasn't mentioned yet?
var someCondition = true;
if (someCondition == true){
document.getElementById('hidden div').hidden = false;
}
<div id="hidden div" hidden>
stuff hidden by default
</div>

Would you want the same form with different parts, showing each part accordingly with a button?
Here an example with three steps, that is, three form parts, but it is expandable to any number of form parts. The HTML characters « and » just print respectively « and » which might be interesting for the previous and next button characters.
shows_form_part(1)
/* this function shows form part [n] and hides the remaining form parts */
function shows_form_part(n){
var i = 1, p = document.getElementById("form_part"+1);
while (p !== null){
if (i === n){
p.style.display = "";
}
else{
p.style.display = "none";
}
i++;
p = document.getElementById("form_part"+i);
}
}
/* this is called at the last step using info filled during the previous steps*/
function calc_sum() {
var sum =
parseInt(document.getElementById("num1").value) +
parseInt(document.getElementById("num2").value) +
parseInt(document.getElementById("num3").value);
alert("The sum is: " + sum);
}
<div id="form_part1">
Part 1<br>
<input type="number" value="1" id="num1"><br>
<button type="button" onclick="shows_form_part(2)">»</button>
</div>
<div id="form_part2">
Part 2<br>
<input type="number" value="2" id="num2"><br>
<button type="button" onclick="shows_form_part(1)">«</button>
<button type="button" onclick="shows_form_part(3)">»</button>
</div>
<div id="form_part3">
Part 3<br>
<input type="number" value="3" id="num3"><br>
<button type="button" onclick="shows_form_part(2)">«</button>
<button type="button" onclick="calc_sum()">Sum</button>
</div>
