I try to pass the content of a paragraph element into a field of a contact form using Javascript

So the problem is this:
I try to get the text that is inside a specific paragraph with a specific id name and pass it inside a contact form .
i tried this
var src = document.getElementById("ptext"),
dest = document.getElementById("inform");
src.addEventListener('input', function() {
dest.value = src.value;
}};
Where "ptext" is the id of the element with the text of the paragraph and the "inform" is the id of the field in contact form.
The above code will trigger when the user clicks a button.
I am new in Javascript so the code above is probably wrong or faulty.
UPDATE: The HTML Code is this :
<p id="pext">Hello this is the text that is to be imported inside the form field</p>
form field:
<input type="text" name="your-subject" value="" size="40" id="inform" aria-required="true" aria-invalid="false" placeholder="Subjext">

I'm not sure if this is what you were trying to do, but if you're trying to get the text of a paragraph into a form field on a button click (useful a lot of the time with hidden form fields), then here is a code snippet to help you:
var src = document.getElementById("ptext");
var dest = document.getElementById("inform");
var getText = function () {
dest.value = src.innerText;
event.preventDefault();
return false;
}
<p id="ptext">This is some fake text that we'll put into the form.</p>
<form onsubmit="getText()">
<label for="text">Info from paragraph:</label><br>
<input type="text" id="inform" name="text"><br><br>
<input type="submit" >
</form>

Hello and welcome to Stack Overflow :)
To get the text that is inside specific paragraph, use
var src = document.getElementById("ptext").innerText;
To assign the value to an input field (which is what I'm assuming you are trying to do), use
document.getElementById("inform").value = src;
If you supply us with HTML element we could be even more precise.

JavaScript- dynamically adding input to a page

i am using JavaScript to add a div on the fly. The div should contain a form input whose 'name' attribute WILL changes in value incrementally.
I have managed to do this- I however have two problems.
First Problem:
The first div that i created is cancelled out by the next dynamically created div.
thus, when i submit the form, the first dynamically created imput form is blank-
but subsequent ones have values on them.
MY CODE :
html
<div id="dynamicDivSection"></div>
<button id="addbutton">add box</button>
<div id="boxes">
<div class="box">
<input type="text" id='dynamic-imput' name="">
</div>
</div>
javascript
var addbutton = document.getElementById("addbutton");
var key = 1;
addbutton.addEventListener("click", function() {
key++;
document.getElementById('dynamic-imput').name = 'ser['+key+'][\'name\']';
var boxes = document.getElementById("boxes");
var head = document.getElementById("dynamicDivSection");
var clone = boxes.firstElementChild.cloneNode(true);
head.appendChild(clone);
});
i suspect that the problem is causing by this:
document.getElementById('dynamic-imput').name =
'ser['+key+'][\'name\']';
i.e when i create the dynamic div it creates several inputs on the page that contain the same Id. if i am correct, then perhaps teh solution is to change the Id of the newly created imput - however, i am not sure how to change the Id of a dynamically created Imput.
Second problem.
i want each dynamically created div to go to the top of the page; i.e to be placed before the earlier created dynamic div- however, at the moment each dynamically created div go directly under the first dynamically created div.

You can insert as the first child with:
parent.insertAdjacentElement('afterbegin', nodeToInsert);
You can get and set attributes such as id with setAttribute and getAttribute. Though I'm not sure why you even need an ID here, it would be simpler not to have one and select the element with a class.
var addbutton = document.getElementById("addbutton");
var key = 1;
addbutton.addEventListener("click", function() {
key++;
document.getElementById('dynamic-imput').name = 'ser['+key+'][\'name\']';
var boxes = document.getElementById("boxes");
var head = document.getElementById("dynamicDivSection");
var clone = boxes.firstElementChild.cloneNode(true);
var clonedInput = clone.firstElementChild;
clonedInput.setAttribute('id', clonedInput.getAttribute('id') + '-' + head.children.length);
head.insertAdjacentElement('afterbegin', clone);
});
<div id="dynamicDivSection"></div>
<button id="addbutton">add box</button>
<div id="boxes">
<div class="box">
<input type="text" id='dynamic-imput' name="">
</div>
</div>

Send selected data back to original window

I have a file called bpSearch. Inside bpSearch, I have a MODAL window, called addNewModal. Within addNewModal, I have 2 INPUT fields called partnerName and partnerCode. I have a button that once clicked, opens into another MODAL window, called searchPartnerModal.
Here is the a portion of the FORM inside addNewModal:
<form action="bpSearch.php" method="get">
<input type="text" readonly id="partnerName" name="partnerName" />
<input type="text" readonly id="partnerCode" name="partnerCode" />
Go
</form>
When the user clicks GO, it opens searchPartnerModal.
searchPartnerModal is where the user will enter either a code or a name (doesn't have to be both). But upon hitting SEARCH, I use an AJAX call that returns JSON that I parse and eventually return in a UL field called pNames. We're still inside searchPartnerModal.
Here is the FORM inside searchPartnerModal:
<form action="bpSearch.php" method="get">
<input type="text" id="pNameSearch" name="pNameSearch" />
<input type="text" id="pCodeSearch" name="pCodeSearch" />
<input type="button" class="btn" id="pSearch" name="pSearch" value="search" />
</form>
When the user enters a name, I use jquery to send it over to a PHP script that will then return the data in a UL tag.
Here is the jquery that will search if the user enters a name:
$('#pSearch').on('click', function()
{
var partnername = $('#pNameSearch').val();
if($.trim(partnername) != '')
{
$.post('api/pNameSearch.php', {partnername: partnername}, function(data)
{
var obj = JSON.parse(data);
$('#pNames').empty();
var htmlToInsert = obj.map(function (item)
{
return '<li><a id="getPInfo" href="javascript:;"
onclick="getPInfo()" data-selname="'+item.FULL_NAME+'"
data-selcode="'+item.PARTNER_CODE+'">'
+ item.FULL_NAME + ' - '
+ item.PARTNER_CODE + '</a></li>';
}).join('');
$('#pNames').html(htmlToInsert);
});
};
});
With this code, I am able to send the name to search the database table for a valid name. The data is returned via JSON and is parsed and displayed inside the UL tag (called pNames) as LI tags, each with an A tag with their own data-attributes, called data-selname and data-selcode.
Now what I need to do is once the user clicks on one of the returned data links inside pNames, I need to send it back to the previous modal window, addNewModal.
This is where I'm stuck.
If you look inside the Jquery above, after I parsed the JSON, you will see that I created another Javascript function inside the A tag of each returned piece of data, called getPInfo().
Here is what I got so far for the function getPInfo() :
function getPInfo()
{
var selname = ($('#getPInfo').attr('data-selname'));
var selcode = ($('#getPInfo').attr('data-selcode'));
}
At this point, I can alert both variables (selname and selcode) and get them to display in an alert window.
What I want to do is send both of those variables back to addNewModal in the respective INPUT fields, called partnerName and partnerCode.
So selname will go to partnerName and selcode will go to partnerCode.
I didn't display the PHP script that returned the data.

Change the anchor id=getPInfo to class=getPInfo since you have multiple anchors. Next, handle the click event of the anchor and extract the data attributes and set the corresponding form elements in the addNewModal form. Following should work based on the markup i see so far.
$(function(){
$('body').on('click', 'a.getPInfo', function (e) {
var $a = $(e.srcElement || e.target);
$('#partnerName').val($a.attr('data-selname'));
$('#partnerCode').val($a.attr('data-selcode'));
$('#searchPartnerModal').modal('hide'); //assuming bootstrap modal
});
});

Is it possible to make input act like a link (Chrome)

I want an input type="button" act like a link to the browser (so, it is possible to right click on the input and see context menu for the links(open link in a new tab, open link in a new window etc).
I have a form with a submit button:
<input type="submit" value="Run Query"/>
In order to create a link and have this context-menu, I replaced input with:
Run Query
But this way "open link in a new tab" opens the same page(due to the href attribute).
I know that you can just ctrl+click on the <input type="submit"/> to open it in a new tab, but if the input tag is present, there is no context menu for it in Chrome.
Is it possible to create an input that would have the same context menu as a link? Or any trick to tell the browser to add this functionality to the input tag?

If I understand your problem correctly, you want to submit the form to a new tab?
Then you could use target="_blank" on the form element.
<form action="" method="POST" target="_blank" >
<input type="submit" />
</form>

This will use the query string to pass the value of each input field to a new window or tab and submit it. It won't work if you're posting files (a workaround would be to immediately upload the file when selected, give it an id and store that in a hidden field, so the file id is the one being posted).
Note that this is an example and you should use something better for dealing with query strings and browser compatibility (it's only tested on Chrome). You should test it thoroughly in other browsers before shipping this! I also have no clue how it's going to work in browsers for iOS/Android/Windows Phones etc. What I'm trying to say is that you probably shouldn't use this.
<body>
<form action="http://google.com">
<input type="text" name="stuff" value="" />
<input type="text" name="q" value="" />
Submit
</form>
<script>
!function () {
var form = document.querySelector("form")
var submitButton = document.querySelector("a")
var queryString = location.search.slice(1).split("&").reduce(function (seed, str) {
var pair = str.split("=")
seed[pair[0]] = decodeURIComponent(pair[1])
return seed
}, {})
Object.keys(queryString).forEach(function (qsKey) {
var formEl = form.querySelector("[name='" + qsKey + "']")
if(formEl)
formEl.value = queryString[qsKey]
})
if(queryString.submit)
form.submit()
submitButton.addEventListener("contextmenu", updateHref) // Update on right click
submitButton.addEventListener("click", function (e) {
if(e.altKey || e.ctrlKey || e.shiftKey || e.which === 2 /* middle mouse button */) {
updateHref()
} else {
e.preventDefault()
form.submit()
}
})
function updateHref() {
var values = [].slice.call(form.elements).map(function (el) {
return el.name + "=" + encodeURIComponent(el.value)
})
submitButton.href = location.pathname + "?submit=1&" + values.join("&")
}
}()
</script>
</body>

Persisting textbox value using jQuery

I'd like to save the newly entered values, so I could reuse them. However, when I try to do the following, it does not work:
// el is a textbox on which .change() was triggered
$(el).attr("value", $(el).val());
When the line executes, no errors are generated, yet Firebug doesn't show that the value attribute of el has changed. I tried the following as well, but no luck:
$(el).val($(el).val());
The reason I'm trying to do this is to preserve the values in the text boxes when I append new content to a container using jTemplates. The old content is saved in a variable and then prepended to the container. However, all the values that were entered into the text boxes get lost
var des_cntr = $("#pnlDesignations");
old = des_cntr.html();
des_cntr.setTemplate( $("#tplDesignations").html() );
des_cntr.processTemplate({
Code: code,
Value: val,
DivisionCode: div,
Amount: 0.00
});
des_cntr.prepend(old);
This is the template:
<div id="pnlDesignations">
<script type="text/html" id="tplDesignations">
<div>
<label>{$T.Value} $</label>
<input type="text" value="{$T.Amount}" />
<button>Remove</button>
<input type="hidden" name="code" value="{$T.Code}" />
<input type="hidden" name="div" value="{$T.DivisionCode}" />
</div>
</script>
</div>

You want to save the previous value and use in the next change event?
This example uses .data to save the previous value. See on jsFiddle.
$("input").change(function(){
var $this = $(this);
var prev = $this.data("prev"); // first time is undefined
alert("Prev: " + prev + "\nNow: " + $this.val());
$this.data("prev", $this.val()); // save current value
});
jQuery .data

If you want old/Initial text box value, you can use single line code as follows.
var current_amount_initial_value = $("#form_id").find("input[type='text']id*='current_amount']").prop("defaultValue");
If you want current value in the text box, you can use following code
$("#form_id").find("input[type='text']id*='current_amount']").val();
