Setting a dynamic drop down value in JavaScript

I've been working on this issue for days and feel like I'm at a dead end so hoping someone can help out.
I have a form that's used to log calls. The form has two drop downs Reason and Resolution which are created using an array.
When a call is dropped for whatever reason I want the user to click a button called Lost Call and have it fill out the form with specific information.
It works for every field but the Resolution field. I can't get that one to populate.
The lost call button calls a function using onClick.
<Input type="button" value="Lost Call" onClick="LostCall()" />
All my code is HTML5 and JavaScript.
Here is my HTML code:
<select id="Reason"><option value=" "></option></select>
<select id="Resolution"><option value=" "></option></select>
The script I use to create the drop downs I got from here:
http://jsfiddle.net/bdhacker/eRv2W/
Other then changing the Variable names to suit my form and less options the code is the same.
The Question is how can I make it to where someone clicks lost call the form is filled out including the Reason and Resolution with specific values when the Resolution values are dynamically generated?
Here is the script for the Lost Call Button:
function LostCall() {
var Reason = document.getElementById("Reason");
Reason.Value = 'Misc/Other';
var Resolution = document.getElementById("Resolution");
Resolution.Value = 'Lost Call';
Using the above Reason is populated but not Resolution. Also note both Misc/Other and Lost Call are options available in the array I'm using.

EDIT: Updated fiddle.
Hmm, your code is working, as I've tried it in this quick fiddle
Are you simply missing a closing } or was that just a simple mistake when typing this question?

if the value you are assigning in the list of options, try this approach:
function LostCall() {
document.getElementById("Resolution").selectedIndex = "2";
}

Javascript code after choosing a file

I need to execute certain piece of code after user chooses file from file input. The tricky part is I cannot check the input for it, so:
$('input').change ->
is out of the question, I need to detect user clicking "Open" button. Is it possible?

You'd need to check the file input's FileList.
<input type="file" id="file">
$('#file').on('change', function() {
return console.log($(this)[0].files);
});
Worth bearing in mind that if you were to select a file and then go back in and choose the same file a second time, the function will not fire as the input hasn't truly changed.
In this scenario you'd need to set a flag somewhere that resets when you click the input (or something similar).

basic live text input without html <input>'s

I'm trying to start a project that requires that the javascript know every word that's typed in. An example of something I would try to accomplish would be that you would type 4 + 4, the interpreter on the webpage knows what you mean, and automatically puts = 8 on to the end of that line to show it's computed it, without having to submit anything or press any button.
I've looked into the element, but I don't want to reinvent the wheel or go against what the spec says. With putting a <textarea> as input on top of a canvas, the javascript on the page can only know what is in the textbox when the user submits the text. Is there anything out there that would help with this?
Thanks in advance!

To get the value of a textarea you can just access it via the DOM:
var textArea = document.getElementById("id-of-textarea");
To the textarea you can attach different eventlisteners, and in your case I would use onkeypress
textArea.onkeypress = function () {
var ta_value = textArea.value;
alert(ta_value);
}
Of course you'd have to write your own interpreter, I wouldn't recommend running eval on the input...

try adding a hidden input element and give it the focus when the page load is complete, and use the onkeyup handler to do whatever u want.

Passing a dynamic text input into a link via javascript

So i've been at this for hours and havn't figure it out and I know there is an easy solution so I figured I would ask here. I am trying to pass the value of a text area into a link as part of a twitter share button. I think the problem is with global scopes I am able to get the variable from within my external javascript but not from my main php file. For example.
Here is the html:
<div id="share_twitter">
Friends Twitter Username (optional) <input type="text" name="friends_twitter" value="#" />
<script type="text/javascript">
window.document.write('');
</script>
Then I have the Javascript in extenral.js which is suppose to get the value of "friends_twitter" and send it back to the main page which will allow me to make a dynamic link to that persons twitter.
I tried this var friends_twitter_input = $("input[name=friends_twitter]"); but got undefined if i do window.friends_twitter_input = $("input[name=friends_twitter]"); it works a bit better but still not as intended.
I also wrote code to detect key change which works but only if it's placed inside of external.js
I may be going about this all wrong but I can't seem to get it staight. Anyhelp would be great.
Update
I'm getting the error "friends_twitter_input is not defined" in firebug but not sure why
inside custom.js
$(document).ready(function(){
var friends_twitter_input = $("input[name=friends_twitter]").val();
$(".twitter-share-button").click(function() {
var friends_twitter_input = $('input[name=friends_twitter]').val();
});
}
inside index.php
<script type="text/javascript">
window.document.write('');
</script>
I think i need to not write the share link until the input has a value or define the value as null.
Thanks for all the help.

Not quite sure about the structure of all your code but a few things that may help.
To get the value from the input button this is the code you need.
var friends_twitter_input = $("input[name=friends_twitter]").val();
Also make sure that the code that tries to read the value of the input text is executed after the input text is in place.
To execute your javascript after the page load use this:
$(document).ready(function() {
//All your javascript here.
});
To hook up to the oncahnge event of the input text do this (inside the ready handler)
$("input[name=friends_twitter]").onchange(function() {
var friends_twitter_input = $(this).val();
});
Please note that the code in the onchange event is just for demo purposes you should probably want to use onblur or better hook up in the onclick event of the submit button.

Calling a javascript file (.js) via Excel VBA?

How to call a javascript file (.js) via Excel VBA?
So as i am opposed to the same kind of problem i'll try to submit you guys my case.
I am trying to automate datas extraction from valeo's catalogue using excel vba macro.
I have a list of références attached to valeo's automotive products (huge list, as more than 3000 thousands items). And i would like to import directly informations from the catalogue wich seems to run under javascript.
The datas i need is the list of every vehicules attached to a reference.
Here is the url: http://outcat-cs.tecdoc.net/ows/en/7FA2A0C501BC34CA4BECB04095663CF1.ows_cs2.srv?view=VIndexFramesetJsp
I'd like to access to the "Direct Article Search" tab, in order to copy a reference directly from an excel tab's cell and then simulate a clic on the reference in order to display the "linked vehicules section" and then to copy them in a new excel sheet.
I already succeede in doing this with html pure programmed webpage (oscaro.com) using the following code :
Set maPageHtml = IE.document
Set Helem = maPageHtml.getElementsByTagName("input")
For i = 0 To Helem.Length - 1
If Helem(i).getAttribute("name") = "toFind" Then Helem(i).Value = "819971" '819971 is the valeo reference searched
If Helem(i).getAttribute("name") = "submit" Then Set Monbouton = Helem(i)
Next
Monbouton.Click 'this does the click on my button Monbouton
But this technique can't be used with valeo website since I am not able (or at least I don't know yet how to do it) to select/click a button when the page is made on javascript, since it doesn't have a name, value or id for the button.
Also it seems that the url in the address field is the same before clicking on the "Direct Article Search" button and after having clicked....
Hope i am clear enought in spite of my english...
Greetings

All the previously suggested approaches sound hacky to me.
For a more reliable solution, embed the Javascript in a COM component via Windows Script Components, and call the Javascript-based COM component as you would any other COM component.

I don't think that there is a direct way to run JavaScript code in VBA.
What you could try to do is to embed the JavaScript code in an HTML form which you could open in a (hidden) browser control. Then fill the form controls via the DOM of the browser control and submit the form. The submit triggers the JavaScript function that you want to call.
Sample (not tested):
VBA:
oIE.Document.frmMain.param1.Value = 5
oIE.Document.frmMain.param2.Value = "6"
oIE.Document.frmMain.submit.click ' this line will call the JavaScript function
HTML:
<div id="submit" > Do Action</div>
<script>
function doAction()
{
// do whatever the code should do
}
</script>

You mean through windows scripting host?
You can shell (use the shell command) out to wscript.exe with the name of the .js file.
But this javascript object model won't be like the one you get in the browser.
It would be helpful if you told us what the javascript was supposed to do.
