Dynamically changing string - correct value not being submitted?

I recently posted another question about how to add content to a string (Dynamically change string with JS?), and I made progress on that front but it seems the updated variable is not being submitted. Am I missing something?
Here is my code:
<script type="text/javascript">
var selections = 'Gender, ';
jQuery(".add-to-form").click(function () {
var title = jQuery(this).attr("title");
selections += title + ', ';
console.log(selections);
});
var ss_form = {'account': 'XYZ', 'formID': 'XYZ'};
ss_form.width = '100%';
ss_form.height = '1000';
ss_form.domain = 'app-XYZ.marketingautomation.services';
ss_form.hidden = {'field_XXXXX': selections };
</script>
This works great in that the correct values are showing up in the console log, but when I submit the form and look in SharpSpring the only value getting through is the initial variable value (Gender, ). Do I need to somehow refresh the variable value in the hidden field?
All help is appreciated, thank you!

The following line is executed on page load:
ss_form.hidden = {'field_XXXXX': selections };
This assigns the value of selections as it is at that moment. The field_XXXXX property is a separate variable that will not change when you assign a different value to selections later.
So when the click event fires, and you assign a new (longer) value to selections, then only that variable changes. It is not connected to the property above.
How to solve? Just do another assignment to the ss_form.hidden.field_XXXXX property within the click handler:
jQuery(".add-to-form").click(function () {
var title = jQuery(this).attr("title");
selections += title + ', ';
ss_form.hidden.field_XXXXX = selections; // <-------
console.log(selections);
});
I assume that ss_form.hidden is some API driven way to set a hidden input element, and that this works. If not, make sure to identify the input element that needs to get a new value, which could look like this:
$('#id_of_hidden_input').val(selections);

How to get the Value of a Dropdownlist in Javascript

This is a really simple problem I can't figure out. I am trying to get the value of a dropdownlist using Javascript. I have 4 digit job codes in my dropdownlist. On a button click I got to this function and am trying to get the value of what was selected when a button was pushed.
function jobCodeToAdd() {
var jobCode = document.getElementById("<%=jobCode.ClientID%>"));
var selectedJobCode = jobCode.options[jobCode.selectedIndex].value;
What am I doing wrong? Thank you for your help.

I think what you are looking for is .text
var jobCode = document.getElementById("<%=jobCode.ClientID%>"));
var selectedJobCode = jobCode.options[jobCode.selectedIndex].text;

crm 2011 xrm.page.getattribute returns null when there is value

I'm not really skillful with JScript but I've written the following code within a function webResource that is supposed to run when the form loads (OnLoad)
var creationDateName = "createdon";
var today = new Date();
var creationDateAttr = Xrm.Page.getAttribute(creationDateName);
if(creationDateAttr!=null)
{
/* Some more code */
}
The problem is that Xrm.Page.getAttribute(creationDateName) returns null when there is a value on the field (the field is not being displayed in form but when looking up it has a value). Funky thing about it is that in my test organization the same code worked like a charm, but when I copied and paste it on the production organization to release the solution it doesn't work properly that's what confuses me a lot. Any idea what might be happening?

You need to use getValue to return the value in the field. Your code is merely checking that the field exists on the Page.
You also need to be aware that in Create mode, these values are not set, so you can't retrieve them. In Update mode they will work. So you need to check that the Page is in Update mode too:
var formType = Xrm.Page.ui.getFormType();
if (formType === 2) // Update
{
var creationDate = Xrm.Page.getAttribute(creationDateName).getValue();
}

it gives you the attribute not the value..
to get the value you have to write code as below
var creationDateAttr = Xrm.Page.getAttribute(creationDateName);
var valueDateAttr=creationDateAttr.getValue();
OR
var creationDateAttrValue = Xrm.Page.getAttribute(creationDateName).getValue();
hope this will help

Silly me, I forgot to add the field I was looking for that's why it return null but thanks to Donal for the answer, actually I was trying to verify if the field was full or was null. Thanks

changing the value of a select box by only having the xpath

I am currently using robotium to record a load of actions in an android web view. There is a known bug in robotium that doesnt let you change the value of a select box. in order to combat this when the test is running i am creating another javascript injection to change it. It works with name and Id but it needs to be able to use xpath as well in case a name or id arent available.
At the moment I can do this using the name and Id of the select box using:
selectBox = document.getElementById(identifyingValue);
or
selectBox = document.getElementByName(identifyingValue);
After this I can create a method to change the value of the select box the value that I want. The issue is that sometimes i cannot get the id or name of the select box and there isn't a similar method to do this via an Xpath ie:
selectBox = document.getElementByXpath(identifyingValue);
My code currently looks like this:
var selectBox;
var identifyingAttribute = ('$identifyingAttribute');
var identifyingValue = ('$identifyingValue');
var selectedIndex = '$selectedIndex';
if (identifyingAttribute === 'id') {
selectBox = document.getElementById(identifyingValue);
} else if (identifyingAttribute === 'name') {
selectBox = document.getElementByName(identifyingValue);
} else if (identifyingAttribute === 'xpath') {
selectBox = document.getElementByXpath(identifyingValue);
}
selectBox.selectedIndex = selectedIndex;
if (selectBox.onchange) {
selectBox.onchange();
}
So far you can see that I am trying to use the id and name first and the xpath as a last resort.
Is they a away that I can select an element by its Xpath and then change its value or perform a similar action. Any help or input would be greatly appreciated.

you can use document.querySelector() and select the property with a css selector.
documentation can be found here: https://developer.mozilla.org/en-US/docs/Web/API/document.querySelector

I have found a solution to the problem using document.evaluate()
The statement works for me:
selectBox = document.evaluate(identifyingValue, document, null , 9, null).singleNodeValue;

Change textbox value in javascript

I want to update the value of text box from where I'm getting initial value to add product to cart.
Now I'm applying round function & I want to update the value of text box that is because I'm using ajax & if I'm applying round function, user must know how system calculated everything.
Here's my simple code:
<script>
$(document).ready(function(){
$(document).delegate('.purchasenow','click', function(e){
var buynow=this;
var productid = $(this).attr('id');
var quantity = $('.quo_'+productid).val();
var quantity = Math.round(quantity);
alert(quantity); //This gives the value
$('.quo_'+productid).value = quantity; //This is not working
});
});
Can anyone tell why it's not working? It's very simple but I'm not able to find out the cause.

Have you tried
$('.quo_'+productid).val(quantity);
The jQuery selector returns a wrapped object, not the actual DOM element. I don't think wrapped object has the .value property

you are almost correct the only thing why it is not working because your syntax is wrong
this is the correct syntax for jQuery
$('.quo_'+productid).val(quantity);
if you want it in javascript
var txt = document.getElementById("quo_"+productid);
txt.value = quantity;
