Reading Barcodes
Apr 25, 2007
I'm trying to create a javascript barcode API, that reads from my USB barcode reader and calls an action upon completion. The reading itself is not complicated at all, since the barcode reader functions exactly as typing the same numbers on my keyboard. So scanning a barcode with; 5050500
would be the same as typing it on my keyboard, but of course much faster. The problem lies in my "API" which dosn't always respond to the barcode length correctly, hence executing the actions at the wrong time (see code below).
A scenario in my application would be to separate multiple barcodes with a semicolon, which is what I'm trying to do with the code below. Copy paste the following code, and run it in your browser: Code:

I'm trying to find a simple step-by-step on how to read a simple XML file
like this one, which will work in IE 6 and Firefox 0.x.
<?xml version="1.0" encoding="ISO-8859-1"?>
<CATALOG>
<CD>
<TITLE>Empire Burlesque</TITLE>
<ARTIST>Christopher Santee</ARTIST>
<COUNTRY>USA</COUNTRY>
<COMPANY>Columbia</COMPANY>
<PRICE>10.90</PRICE>
<YEAR>1985</YEAR>
</CD>
<CATALOG>
The problem is every example, I find that it will work in IE but not Firefox
or visa versa, could someone please point me to a how to that will work with
both browsers. I just spent two weeks reading the Microsoft Press Book "XML
Step by Step", only to find out that the technology only works with IE.

Can someone give me some pointers on how I can read one or more
arguements from a url, using js?
Why? I'm working on a LAMP based project and when a user successfully
registers, the header redirects to the login screen - I'd like to check
for the value of register, if read from:
http://www.mydomain.com/index.html?register=success
A pointer/hint as opposed to a solution should be sufficient because I'm
doing pretty well learning javascript.

I'm extremely new to XML, tell me what needs to be fixed in my XML file
as well as in my javascript.
My XML file looks like this:
<?xml version="1.0" encoding="iso-8859-1"?>
<imapmail>
<message>
<subject>Testing, 123</subject>
<sender>Name <email@example.com></sender>
<date>1/2/03</date>
<size>640 KB</size>
<read>0</read>
</message>
</imapmail>
I'm accessing it with this javascript:
var sender =
xmlDocument.getElementsByTagName("sender").item(0).firstChild.data;
I ultimately want to user to see that the sender is "Name
<email@example.com>". With the way the XML file is currently set up
(sender is Name <email@example.com>), the only that shows up
on the javascript end is Name. Is the way I'm storing it in my XML file
the best way to be doing it?

I'm trying to write code that will read an XML file. I've found several examples but I can't get them to work. Am I missing a DLL file? The errors I commonly get are "object required" (as with the code below) or "permission denied". Any insight would be helpful and appreciated. Here is what I'm trying:
<script language="JavaScript">
function importXML(file)
{
xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.onreadystatechange = function () {
if (xmlDoc.readyState == 4) createTable()
};
xmlDoc.loadXML(file);
}
function createTable()
{
var doc=xmlDoc.documentElement;
var x = xmlDoc.getElementsByTagName("Employee");
for (i=0;i<x[0].childNodes.length;i++)
{
alert(i); //enter code to process stuff here
}
}
</script>
<INPUT TYPE=button VALUE="import XML"
onClick="importXML('C: mpzip est1.xml')">

I am having problems reading the value of a text Node. I think it has to do with the fact that the text is in a <span> tag.
I have a table and in each <td> I have text + a checkbox. I want to retreive the text next to the checked checkboxes and concatenate it.
Here is my Code:

From javascript, I am opening a popup window and requesting a url, which sends a xml as a response to the popup window. From this javascript, I want to read that xml content:
<?xml version="1.0" encoding="ISO-8859-1"?>
<aaa>
<vvvv><![CDATA[1]]></vvvv>
</aaa>
I tried
del_window=window.open("http://abc.com/_xmlservice","","width=1,height=1");
var ele = del_window.document.documentElement; //this is returning "HTML"
...
and
del_window.document.getElementsByTagName("xxx")
But nothing worked out.

reloading an XML file that I'm reading with AJAX. I'm looking for a way to refresh this XML when the page is refreshed so I know that the data is up to date. It only needs to happen when the page is reloaded. one solution suggested something like this
Code:
var xmlhttp;
function loadNewsContent(url)
{

But that doesn't work at all and I don't know why.

Is there a way to download another web page using javascript and read
through it.
I am not too concerned with displaying the web page just downloading
it. Has anyone done anything like this? the closest I have found was a
procedure used by grease monkey "GM_xmlhtt" which is what I am looking
for.

I was working with Gdata to access the data in my google calander.
I want to do this with a simple HTML-JS page, no server side scripting
(hitherto dont know if this is practical).
For this I need to read the HTTP headers for a GET response. Can anyone
tell me if its possible to read the HTTP headers with Javascript or by
some other method on client side.

In my applications I've a ton of scripts that use remote XML file to fill forms and evaluate contents; In these scripts I always use the method SelectNode (that, with some workaround, works fine also in Mozilla).
I've just found out that this method doesnt work in Safari browser, therefore my applications are not usable by this browser. Can anyone provide me any solution or workaround to be able to read XML
files in Safari wihout rewriting all of my scripts?

I have this:

What I would want to do at that point is get either the
contentWindow.document or the contentDocument depending on whether this
was IE or Mozilla. (Thanks Lasse.)

I have been using document.cookie to write and read cookies.
Unfortunately, when I open my page in Internet Explorer, I don't see
what I wrote to my cookie while in Netscape Navigator. Similarly, my
page that I opened in Netscape doesn't see what I wrote to the cookie
while in IE.
Surely there must be away for IE and Netscape to read the same
cookie information ??. Otherwise, what happens if a user just happens
to be browsing my page in both browsers? They'll expect things to be
there, and they won't be there because one browser doesn't see what
was written in the other.
Any ideas on how to get Netscape to read cookies written by IE, and
visa versa?

I am having an issue reading from a div that is being changed. The div in question was initially empty. A function that was called upon the selection of something in the drop down list creates another drop down list within that div (sets the inner html). Now, I have another function that needs to read from this new drop down list. However, when I use alert(document.getelementbyid('divid').innerhtml) in the function it returns undefined. The drop down list is created successfully and populated by the relevant data. The method of creation was calling another php file that created the list after querying a database.

I need to use a javascript variable when reading a value from a asp array. Currently I have a windows app that has a webbrowser. The windows app invokes a javascript method through the webbrowser and this javascript method returns an object. This object is built in the javascript function using values which exist inside a classic asp array. The function that sits on the relevant asp page, is invoked from my windows app and then returns the object to the windows app is below.
function item(count){
var pid;
var description;
var fullprice;
var discountprice;
var quantity;
var size;
this.pid = '<%=SBagArray(0,count) %>'; //ProductId
this.description = "<%=SBagArray(1,count)%>"; //description
this.fullprice = <%=SBagArray(8,count) %>; //Fullprice
this.discountprice = <%=SBagArray(9,count) %>; //Discountprice
this.quantity = <%=SBagArray(6,count) %>; //Quantity
this.size = <%=SBagArray(2,count) %>; //Size
this.getPid = function() { return this.pid; }
this.getDescription = function() { return this.description; }
this.getFullprice = function() { return this.fullprice; }
this.getDiscountprice = function() { return this.discountprice; }
this.getQuantity = function() { return this.quantity; }
this.getSize = function() { return this.size; }
}
My problem is that the variable 'count' is not recognised by the asp. So, how can I use this variable in such a way that it works?
