Retrieving Form Value

Jul 23, 2005

I have:

1 form on the page. (no name, no id value set.)
3 hidden form elements named: catalog, vwoidc, oid

!!! I can only include the javascript right after the body tag. The
form is found near the end of the loaded page.

<form action="actionURL" method=post>
<input type=hidden name=catalog value=store>
<input type=hidden name=vwoidc value=69a6e1deb02417250691>
<input type=hidden name=oid value=60323></form>

Everything I've tried needs to have the javascript executed after the
page has been fully loaded.

Retrieving The ID Names From Within A Form

Jul 20, 2005

Is their a way of iterating thru each tag within a form and returning the
value given in the id property, by that I mean the below html would return
the values idBoxOne, idBoxTwo, idBoxThree from the FormXX form.

<form name="FormXX" method="post" action="default.htm">
<input id="idBoxOne" name="bxOne" type="text">
<input id="idBoxTwo" name="bxTwo" type="text">
<input id="idBoxThree" name="bxThree" type="text">
</form>

Up to this point I've only used JavaScript to change CSS properties,
innerHTML and outerHTML so I'm rather new to the game.

Retrieving Form Values In Javascript

Sep 29, 2006

I am trying to create a form for authorised users to upload photos to
an image gallery. I'm attempting to perform simple validation of the
fields by ensuring the fields aren't empty and that the extensions are
right. However, I can't seem to access the actual values of the fields
to start with.

If I simplify my problem, can anyone tell me why this would work in a
Javascript alert:

alert(document.form.Photo1.value);
//This outputs 'D:/images/x.jpg'

but this won't:

var photonumber = "Photo" + 1;
alert(document.form.photonumber.value);
// I get "undefined"

The reason I'm doing this is because I'm looping through a finite set
of images and need to check each one is valid.

Is it because I'm not initialising the "photonumber" string correctly?

CPU 100% On A Loop While Retrieving Form Values

Jul 20, 2005

I have a form with a lot's of number of Text and Hidden Fields. I just do a simple loop to get each value for each attribute. I have about more than 2000.

if i do something simple like :

for (var i=0; i<2000; i++)
aValue = i+10;

it runs well. But if i do something like
for (var i=0; i<2000; i++)
aValue = document.myForm.elements[i].value;

it gives me 100% CPU for a long time before i submit the form.

Retrieving Dom Element Number In Form

May 27, 2004

Is there a way to retrieve the DOM element number in a form? For instance if I had 5 checkboxes with the same name and an event was fired to gather data, could I determine the DOM element number for each checkbox checked? I know this may seem like meaningless information, but I need it to do some other work on the page.

Retrieving Values From Html Form?

Aug 18, 2010

So I'm a novice coder and have been trying to piece together a (seemingly) simple function. I want the user to be able to enter in a certain amount of time into a form, and then when they click submit, it opens a new page and closes after that amount of time.There is a very simple form on the first page that accepts input and looks like so:

<form action="onbreak.php" target="_blank" method="POST"><p class="fillable">I would like to view <input type="text" name="url" id="url" value="" size="30"/> for <input type="text" name="timeinput" id="timeinput" value="" size="3"/> minute(s). <input type="submit" value="Break Me!"/></p></form>

Retrieving Value Of Dynamically Generated Form Fields In Firefox?

Mar 1, 2009

So, I have a form that, when the user clicks on a link, uses J/S to generate extra form fields for extra information. I can retrieve the value of the dynamically generated fields using $_POST in I.E., but it doesn't work in Firefox (no value is returned). Retrieving values for the static fields is fine in both I.E. and Firefox.

Here's the code - is there a function I'm using that could be replaced with something more friendly to Firefox?:

<script type='text/javascript'>
var i = 1;
function addArea() {
var newArea = addElement();

Retrieving Cookies

May 15, 2006

I have the code below that will retrieve a cookie that was placed by the server (ie: joes.com) that the document resides on. I want to be able to retrieve a cookie set by another server (ie: freds.com) but I want to retrieve it from a page served by joes.com. This code apparently using 'document.cookie' determines the server that the document resides on and looks for cookies from that server. Anybody know of code that will let you determine the server?

var name = "cookie";
function getCookie(name) {
var cname = name + "=";
var dc = document.cookie;

if (dc.length > 0) {
begin = dc.indexOf(cname);
if (begin != -1) {
begin += cname.length;
end = dc.indexOf(";", begin);
if (end == -1) end = dc.length;
return unescape(dc.substring(begin,
end));
}
}
return null;
}

Working With XML And Retrieving Nodes

Nov 14, 2004

function Xml_feed(file)
{
this.load = function()
{
var txt, str, title;
var threads = xml.getElementsByTagName('thread');
var len = threads.length;
var box = document.getElementById('box-a');
while (len-->0) {
txt = document.createElement('button');
title = threads[len].getElementsByTagName('title');
str = threads[len].getElementsByTagName('author');
txt.setAttribute('label', title[0].childNodes[0].nodeValue + ' by ' + str[0].childNodes[0].nodeValue);
box.appendChild(txt);
}
};

var xml = document.implementation.createDocument("","",null);
xml.onload = this.load;
try {
xml.load(file);
} catch (e) {
alert('There was a problem loading the XML file');
}
}
var feed = new Xml_feed('blah.xml');


in the red:

Is that how I should be retrieving the value from a child node? (the getElementsByTagName)..

in the blue:

I tried doing this.xml but had problems with doing that, i.e,
this.xml = document.implementation.createDocument("","",null);
this.xml.onload = this.xml.load;
try {
this.xml.load(file);
} catch (e) {
alert('There was a problem loading the XML file');
}
I'll guess that text in the red is why..
btw, this was in an XUL app.. not sure how much that would matter though..

Retrieving Certain Text From A Webpage

Dec 27, 2010

For a personal project, I want to see if I can make a Greasemonkey userscript (or eventually a Firefox add-on) to list how far a certain ad on Craigslist is from where the user is (by the city listed beside the ad). My question is really just looking for ideas on how I can parse out the city's from the webpage text (with javascript or some other language?). Not even sure if this is possible.

The city's or ads aren't their own div elements or anything (nothing can ever be so simple) - but the city's listed are formatted by <font size="-1"></font>, and each ad is in it's own paragraph tag.. maybe I can use that somehow?

Retrieving The Value Of A Readonly Text Field

Jul 20, 2005

I'm not sure why I'm having problems with this but if I try to retrieve the
value of a readonly text form I get back that the object is undefined.

The reason the text is readonly is because it's a date which I set via a
calendar javascript program (associated with a button) only so the user
can't put something silly in requiring validation.

The form send the data correctly when submitted it just doesn't seem to be
able to be read.

Retrieving Keyword In Alert Box To Welcome Visitor

Aug 13, 2010

I am looking to insert a keyword in to a javascript alert box when someone visits my website, so say they came from codingforums, it would say "Welcome, CodingForums.com Visitor". My keyword will be passed from the ad platform I am working with and shows up correctly in the tracking, so I'd imagine it's just a case of having the snippet of code for it to show in the alert, correct? If there is no keyword, I would just like it to say "Welcome Visitor" or something.
