JQuery :: Width() On Newly Created Div Returns False Value?

May 18, 2011

When I create a new div and insert it with .append(ndiv) to an existing div ndiv.width() returns the width of the parent div instead of the actual value. This is the same in FF4 and IE9 so I suppose this is a regular behavior and I just don't realize how to deal with it.

Simple XmlHttpObject - Alert Returns A Value Of Null

Feb 10, 2010

When using the code below the alert returns a value of null. In the past this has never happened, it has always returned the xml file I'm requesting. I have noticed a strange difference between browsers. This script is used to fill a form automatically. In its current state it works perfectly in opera, but does not work in firefox or IE (used to work in all the browsers). I'm by no means a javascript expert, am I missing something here?

Textarea Populated But Post Returns Null

Jun 18, 2011

I have a form in which I preset some text inside a readonly, disabled textarea using javascript ('data' being the text):
document.getElementById("link_of_current_view2").value = data;

However, once I call my .php script to process the form, the element is null. How do I get it to pass along that data, which is in the textbox when the user views the form?
<div id="sendlink" class="contact_form" style="z-index:10;">
<a class="close" onclick="document.sendlink_form.reset();return false">CLOSE</a>
<form id='sendlink_form' name='sendlink_form' method="post" action="sendlink.php" >
<label for="link_of_current_view2">Link: </label>
<textarea id="link_of_current_view2" name="_of_current_view2" class="link_of_current_view" rows="2" disabled="disabled" wrap="soft" size="58" value="" readonly="readonly" value=/>

Regular Expression Match Always Returns Null

Feb 12, 2010

I found this regular expression on the internet and it works fine when I test it in various validators on the web.

Code:

^(((0?[1-9]|1[012])/(0?[1-9]|1d|2[0-8])|(0?[13456789]|1[012])/(29|30)|(0?[13578]|1[02])/31)/(19|[2-9]d)d{2}|0?2/29/((19|[2-9]d)(0[48]|[2468][048]|[13579][26])|(([2468][048]|[3579][26])00)))$

It's purpose is to check for valid date and allows formats mm/dd/yyyy, m/dd/yyyy, mm/d/yyyy or m/d/yyyy.

When I try it with the code below it always returns null.

Code:

function isValidDate(/* String */ p1_date) {
var x = "^(((0?[1-9]|1[012])/(0?[1-9]|1d|2[0-8])|(0?[13456789]|1[012])/(29|30)|(0?[13578]|1[02])/31)/(19|[2-9]d)d{2}|0?2/29/((19|[2-9]d)(0[48]|[2468][048]|[13579][26])|(([2468][048]|[3579][26])00)))$";

Double Ajax Calls, Using $F The Second Time Returns Null

Feb 11, 2006

I'm using the $F of the prototype library to send data through the Ajax
Request. I'm having problems using the $F to reference fields sent
back through an original Request. My first request sends a form back
to the user in the type such as <input text name=foo> and at the bottom
of the returned form I have a second ajax call to send the fresh data
to the another script. The problem is that the new data in the form
cannot be referenced from $F. My question is how can I pass the new
data in the javascript to another Ajax call either by $F or by other
means?

Accessing Width Variable - Returns Undefined

Feb 13, 2009

I am trying to access the width variable from my main page. Within the imageinfo.js script functions I can alert() the width value which returns 1024. But I can't seem to pass this variable to my main page or access it directly so that I can use document.write() to write the variable on the page. Whenever I try to call the 'width' variable directly from the main page I get undefined. How can I access this variable? However, with the test code below, I was able to get ducument.write() to write the 'width' variable on the page but now the page doesn't stop loading - there's an endless loop in the code...

Code:
BinaryAjax(url,function(http) {findEXIFinJPEG(http.binaryResponse);test(width)},null,useRange ? [0, Range] : null);

Main page
Code:
<html>
<head>
<script>
function test(width){
document.write('Image Width = ' + width)
} </script>

<script type="text/javascript" src="binaryajax.js"></script>
<script type="text/javascript" src="imageinfo.js"></script>
</head>
<body>
<script type="text/javascript">readFileData('image.jpg')</script>
</body>
</html>

Imageinfo script - This script uses the binaryajax script found below.
Code:
/*

ActiveXObject("Microsoft.XMLHTTP") Returns Null?

May 1, 2007

Just trying to create a basic xmlhttpobject.
However, the following always returns null

xmlhttpobj = New ActiveXObject("Microsoft.XMLHTTP")

(it is Microsoft. and not Msxml2. I've already narrowed that part
down; just trying to create the object now)

If I check for the value of xmlhttpobj, it is always null or
undefined.

IE settings aren't blocking any ActiveX

Document.getElementById Comes Out NULL Help!

Jul 20, 2005

Basically i'm trying to draw a box over an image which
is turning out to be a nightmare. The problem i'm getting at the moment
is that i'm creating a line with <div which works when it's not hidden
but I need to be able to make it hidden so I can use layers to show all
when it finished drawing to make it smoother. This is how some other
scripts are doing it that i've seen. So i've got it drawing a line and I
need getElementById to pick out the layer but it's only picking out NULL
with the one i've got enabled below. I've tried the others but they just
come out as errors. I need to get top2 which is the <div line to show
itself but I can't seem to reference it by getElementById. I use linux
mozilla so i need it working in mozilla as well as windows that's why
i'm using getElementById. My code is below any ideas anyone?

'document.myform.finish' Is Null Or Not An Object : Line 91, Char 2

Aug 31, 2005

I know for a fact that it is an object and I'm pretty sure that it isn't null. I will give you a link to the page that I'm troubleshooting even though it's embarrassingly ugly. Does anyone have
an idea of why it's not seeing the <select name=finish> on Line 183 in <Form Name="myform">?
