I am trying to retrieve data from an XML using this code.
$.ajax({
type: "GET",
url: "http://beermapping.com/webservice/loccity/bb6c5a3fc5baea379be645636e8e6324/Barcelona",
[code]....
I have a following string:
var myHTML = "<html><body>testing hope this work in html</body></html>";
alert($(myHTML).children("body").html());
Why does the alert return NULL, instead of "testing hope this work in html" ???

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.

Suppose I have the following inside a function:Code JavaScript:document.getElementById('display_content').innerHTML = "hello";The above works.However, when I define it like the following it says display_content is null on firefox error console.

This seemed like it should be so simple. It works fine in Firefox, but not in IE. The goal is to disable the form's Submit button, until the question is answered. (The alert is for troubleshooting.)
Code:
Obviously, this HTML is in a form:
Code:
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?

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=/>
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)))$";

I'm trying to figure out the width of all the ul element inside a li, which works fine for the subnav. But the ul for the subsub nav always returns a width of 0, which is incorrect.You can see an example on this page. The second tab is the one that has a sub navigation.I use a simple line like this to get the with of the ul element
Code:
var e_size = $("#testnav ul").width();
//shows 95 with alert

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?
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.

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
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?
