Retrieving Value Of A Dynamically Created Input Field

Feb 12, 2011

I've dynamically created a new field by using appendTo.

i.e.

PHP Code:

$("<input type='text' id='field' value='1'>").appendTo("body"); 

If I try to access the value of this dynamically generated field (i.e. $("#field").val()), I don't have any value returned. I understand this may be because jquery doesn't detect it as being a part of the DOM or something along those lines.

Creating And Writing Variable To Form Input Field

Apr 10, 2011

I am working on a javascript for my blackberry. I am trying to capture the latitude and longitude of that phone. I am able to get the coordinates in an alert box but am having a little trouble writing it to a form input field.

<!DOCTYPE html PUBLIC
"-//W3C//DTD XHTML 1.0 Strict//EN" "[URL]">
<html xmlns="[URL]" xml:lang="en" lang="en">
<head><title>GPS Testing</title>
</head><body>
<script type="text/javascript">
if(blackberry.location.GPSSupported){
document.write("Your device supports GPS locating");
blackberry.location.onLocationUpdate(window.alert("Latitude: " + blackberry.location.latitude + " Longitude: " + blackberry.location.longitude));
var lat = blackberry.location.latitude();
var lng = blackberry.location.longitude();
blackberry.location.refreshLocation();
document.write(lat);
}
</script></body></html>

I am only able to test with Blackberry. I was trying to create a couple of variables with the "var lat =" and var lng =".
With this script I get the alert window and when I click ok it writes "Your device supports ...".

JQuery :: Two Input Fields / Give Second Input Field Always Same Value As Input Field One

I am having a form with two input fields. I want to enter some text in the first input field and then the second field should get the same text. Is there a simple way (maybe a plugin) to do this with jQuery? It would be perfect if I even could output all these input fields values as normal text in <p> or <li> tags.

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.

Js Stop Working - Show Google Suggestion While Typing In An Input Field

Dec 12, 2011

I had a beautiful script written by @rnd me that looks like this:

Code:
<body>
<input id='inp' /> <select id='sug' />
<script type='text/javascript'>
function el(tid) {return document.getElementById(tid);}
function addScript(u){
var head=document.getElementsByTagName('head')[0],
[Code]....

This script made it possible to show Google suggestion while typing in an input field. The Google suggestions are retrieved over here: [URL] The problem is that all of the sudden it stopped working! For apparently no reason because Google is still 'providing' the suggestions online. So I have two questions: Why is it stopped working? Did Google restrict the suggestions to third parties?

Retrieving A Variable And Then Incrementing And Displaying Onclick?

Feb 10, 2010

Simply put, I need to take a variable (The number '20' in this case) that is displayed by an input box on my web page and plug it into a function so that whenever I click on a button, the number in the input box will decrease by 1.

Seems simple enough, though for hours I've been going at it with no luck. Skipping the rest of my code - I currently have:

<head>
<title> Online Slots </title>
<script type="text/javascript"
src="http://dave-reed.com/book/random.js">

[Code].....

The entire code is a slot machine project that's supposed to be extremely simple where you hit the button and it spins 3 wheels, 3 of the same image and you win. Every spin takes $1, every win gives $13.

The majority of the code is already working, however for some reason I appear to be failing badly at getting the read out to show a decrement of $1 every time you push the button.

I've tried so many different ideas that I've found across w3schools, webdevelopersnotes, dave-reed, ect - and so far I haven't been able to get any of them to work correctly.

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..
