I have problem rendering vector layer on map only when is viewed from server. Local all is fine.
I'm using openlayers in combination with gpx file and txt for poi loations around route.
Look my code.
Here is link on webpage: [url]
Here is link on function: [url]
So. there should be red vector line reprizenting route from gpx file, but it is not. That is problem. when viewing localy on my pc, everithing is fine and working.
I am developing extension which should upload currently displayed html as a file to a remote web server, unfortunatelly so far i haven't suceeded. I think this should be done through XMLHttpRequest(), but neither I know how to upload files through XMLHttpRequest nor how to convert string to file.
The HTML form that uploads a file:
But as I said i need my plugin to do it automatically and file must be made from html code.
Layer writing in Netscape. This is pretty straightforward >> However I'm trying to write to a <div> layer within a <div> layer.
My div:
Code:
<div id="blah">
<div id="aight">

</div>
I'm trying to write to "aight"
How should my code look?
A while ago I wrote a "Vector data type" script
using DOM interface to select.options.
That was a (beautiful) mind game :-) rather than
a practical thing to use.
Here is another attempt open for criticism, this
time dead serious. I really need an effective
Vector emulator for a project (as much effective
as something not implemeted in language but
emulated by means of the language itself is: a
productivity impact is imminent, the question
is to minimize it).

I have created a floating layer using Javascript that remains always on top of page on scrolling.Issue is,at some point while scrolling,the layer flickers continuously.
The html page is as follows:
Many common software systems, JavaScript has a history of security problems. Many of these problems could allow a person with malevolent intent to steal sensitive information from a visitor. The number and type of such holes in security vary among browsers and operating system versions. Most JavaScript security holes have been caught and fixed, but new ones are being discovered all the time. For a list of current security holes check out your browser's and operating system's Web pages. As a Web site author, it is your responsibility to keep up-to-date on the current status of known security holes in the applications you create.
Signing Scripts. In Chapter 11, I explained that JavaScript does not provide the ability to directly access files on the client computer. This can be a very large hurdle to overcome if you're trying to upload a file to a server from the client computer. Fortunately, file uploading is one of many functional enhancements that signed scripts provide. Signed scripts are specially packaged scripts that have been verified and signed to be correct and non-threatening. These scripts have additional rights on the client computer that allow a programmer to do many things that he wouldn't otherwise be able to.
With the introduction of Netscape 4.0, a new security model was put in place that would allow digitally signed scripts to bypass some of the restrictions that had previously been placed on them. A signed script can request expanded privileges from the visitor and, with the visitor's permission, gain access to restricted data. A signed script requests these additional permissions through LiveConnect, which allows your JavaScript code to communicate with the Java Capabilities API. The security model allows JavaScript to access certain classes in Java in order to extend its functionality while still maintaining tight security for the client.
A digital signature is a fingerprint of the original programmer, and it allows the security model of the browser to detect where (or from whom) it originated. A script signer can be a person or an organization. By signing a script, you acknowledge yourself as the author and accept responsibility for the program's actions. A signed script contains a cryptographic checksum, which is just a special value that ensures the signed script has not been changed. When a digital signature is detected, you are assured that the code has not been tampered with since the programmer signed it.
Once you finish writing a script, you can use the Netscape Signing Tool to digitally sign it. Signing a script does the following:
Unambiguously assigns ownership of the script to a person or organization.
Allows an HTML page to use multiple signed scripts.
Places the signed script into a Java Archive (JAR) file.
Places the source of the script in the JAR file.
Once a user confirms the origin of the script and is assured that it has not been tampered with since its signing, he or she can then decide whether to grant the privileges requested by the script based on the validated identity of the certificate owner and validated integrity of the script.
JAVASCRIPT FILE IS AS FOLLOWS:
AND CSS FILE IS AS FOLLOWS:
At some point while scrolling,the div 'movable' flickers continuously,while at some other point,it is perfectly stable.
I can't figure out this math problem. I have two points p1(30, 20) and p2(30, 221) and the parametric equation of the vector is (x-30)/(30-30)=(y-20)/(20-221)=t x=30, y=20-201*t
I'm thinking t is the magnitude or the distance. For a point P which is 10 pixels away from p1 on the vector, x=30, y=20-201*-10 (should be around -0.85) which is not the right P i'm looking for. Where am i doing wrong?
I have the following JavaScript (see below). The script requests an XML file from the server and displays it on the page.
The script works fine when the requested XML file is stored on the same server as the script.
The problem is when I try requesting an XML file from an external server such as the National Weather Service. I get an error. If I take the XML file from the National Weather Service and save it to my server it works. Why can't I use my script to request XML files stored on external servers?
Javascript Code
window.onload = initAll;
var xhr = false;
function initAll() {
document.getElementById("makeTextRequest").onclick = getNewFile;

I'm trying to write a script that will be loaded from one server into a website on another server. This script is trying to talk (ajax) to the server that it comes from but I'm getting "Access Denied" errors. I'm well aware that cross-domain calls are not allowed for security reasons so my question is how does Google Analytics work because essentially thats what I'm trying to accomplish. I can embed a Google Analytics script into my website and it'll gather data and send it back to Google.

I found this and it worked just excellent for me! I just want to share it because it wasn't easy to find.
I created a js document with code:

Now, I can use this js within a html like this:
HTML Code:
You may change your machine date/time and check both dates.
I would like to open an html file locally (not fetch it from a server) and somehow use javascript to fetch the relative resources from the server. One solution would be to convert all of the relative links to absolute links. I can convert the html source file anyway I wish, but ideally I would like to modify the html source as little as possible, for example insert a function that modifies the result of the src attribute. How would I go about this? Is there any trick I can use to define where the relative home is? Am I going to get into any scripting security gotchas?
View 3 Replies View RelatedI am creating an XML document on my page with javascript. My question
is, is it possible to save that xml file on the server (I have write
permissions) only using javascript, ie no server code? This task would
be trivial using server code, but I was wondering if I can do it all
with client code and post backs? Well, any input?
I already have a server connected to clients, clients send msgs and it echoes back to all of them and now i want when a client sends a msg it echoes on his server and the other server too .. so when any of the clients on any of the servers sends a msg it is broadcasted all over the servers to all clients

How can I make the button call the click event so that the server side method btnExecute_Click() can be called? Also, this button calls a javascript function before server side even.
I am trying to make a banner the size of the with of my screeen, in
a layer.
BUt I also want to fade it to a complete transperency to reveal the contents
of what's behind it (my page ofcourse) and possible close or hide the faded
layer.
I've seen stuff like that happen in a flash everonment. I was thinking about
using a transition at first to go from one page to another with an
introductory page.
But I rather have everything on one page and just fade the introdutory layer
into the page. Is that too much work for jscript?
I have a strange behaviour when applying onmouseout to a layer. it is
not trigged when the pointer goes out of the _layer_ but when it goes
off the _text within_ the layer.
I want to create a layer that 100% wide, 200 px high and stays at the
bottom of the screen, even when the page is scrolled, how do I do this?
I have seen it on websites but can't find any example code ...
Can someone please tell me how to print a single layer?
View 3 Replies View RelatedI have written a javascript routine that populates a parent document
with a series of <iframe>s. Each <iframe> receives its contents from a
series of separate smaller HTML files. Of course my NN 4.8 browser
doesn't deal well with the <iframe> so I wrapped the code that generates
the <iframe> in <ilayer> tags. NN now recognizes the contents.
However within each of the 'content' files I have another javascript
routine that basically displays the file name (via document.URL &
document.write) of the content file. My IE 5.5 & Mozilla 1.5
understands this perfectly. However my NN responds to the document.URL
with the wrapper/parent document's URL, not it's own unique file name.
I've named/ID'd the iframes & ilayers. If the document.URL fails I can
still make use of the ilayer ID but I need to know the index into the
layers array. I can hard-code a index value into the
document.layers[x].name but given that the position of the particular
content file is dynamic within the parent, the index is going to be
wrong 9 out of 10 times. There doesn't seem to any way for an i/layer
to know who it is Code:

I am using javascript to open a new window like this:
printpreview=window.open('printview.php','printpre v','width=600,height=600');

I have an image on a web page within a css layer:
<DIV ID=MyLayer
STYLE = "position: absolute;top:68px; left:563px;
width:640px;height:480px;">
<IMG src="ReportImageBox_12.54.52.png" width=640 height=480></IMG>
</DIV>
I need that the parts of this layer which have a certain color
(for instance "white") be rendered transparent.
My question. Is it possible to have a simple javascript function
to incorporate in the web page which does this?
I was wondering if it was possible (and if so how) to put a layer ontop
of frames. What I mean is that I would be able to put anything,
including tables ontop of frames so that it could go ontop of two
frames at once, independent of everything else.
Also if it is possible, how would I make it stay still, evenwhen the
page is scrolled... like so that it doesn't even giggle or anything it
stays fixed..
Also, on another subject how would i make it appear next to the top
right hand corner of a cell in a table?
Can someone help me figure out how to show a hidden layer *ONLY* if the
browser is IE for windows? I want it to remain hidden for everything else,
Netscape, Opera, Mozilla and anything for Mac. I'm not having much luck
out here.
this is driving me nuts. I'm not new to programming, except that I've been avoiding Javascript for long time and now it's biting me back.
I have form in which I have among other element a series of checkboxes. These have different id, and values but same name attributes. These attributes are populated with good old ASP spaghetti code.
When I check the box, I want a Div tag called "floatleyer" to populate with a duplicate checkbox and it's value ( a string). So now we have pair of check boxes one the page and a matching one in the div area. If you un-check either box of the matching pair the other member of the given pair gets un-checked as well. In addition, the box and value string from the floatleyer is completely removed.
