Remote Javascript Hanging My Pages?
Oct 28, 2002
I'm not sure what this is called, I think it's remote script execution, but I could be wrong, so bear with me.
I have a call that I make for an adserver:
<script src="http://www...."></script>
That populates the page at that point with some text. When it works, it works great, the text comes back, and everything is good. However, when the remote server does not return right away, or maybe the connection is down, my page hangs on it.
So my question is, is there a way to structure the call on my end so that my page continues loading even if this call doesn't return?

My HTML pages have a <SCRIPT SRC=http://remote/script> at the top'ish
of each page. Sometimes the remote host (probably due to heavy load or
flaky network connectivity) doesn't respond for a long time. This
causes the whole page to appear hanging without anything loading.
Is there some trick I can use with settimeout() so that if the remote
script cannot be loaded after, say, 30 seconds, then I can tell the
page/browser to cancel loading that script?

A newly added, not-quite-wanted function of my job is remotely
debugging JavaScript errors on other people's web applications. I have
tried finding a JavaScript debugger that would allow me to do that, but
other the Microsoft Script Debugger, I couldn't find any other.
Are there such programs? Basically, what I'd like to be able to do is
trace commands step by step and view the values of certain variables.
I was unable to figure out how to get Microsoft Script Debugger to
work. I read the documentation and executed it, but I keep getting
"Syntax error" messages whenever I want to see the value of a variable.
Add to that the fact that I am not a developer and I do not know
JavaScript (other than to read it, which is enough for me to figure out
what the problem is) and you see my problem.
I have read about the option of adding message boxes all over the
place, but this would not work out for me either, since I would need to
make changes to this code on the web server, where I don't have access,
and it would be a lot more tedious.
For those skeptical as to why I still expect to be able to debug
problems:
The problems are caused in most cases by the proxy we add on their web
servers, and they are due to values being changed on the fly. I only
need to find out where the code breaks and read the values of the
variables, which gives me the solution ("do not change this variable").

I want to populate my client's webpage (Remote Server) automatically
through my Server and Database by having him just paste a javascript
on his webpage.
I have read up about Microsoft Remote Scripting but the documentation
states the following : "The server which you make remote scripting
calls must be the same server from which you requested the client page
containing the requests."
In my case , the client and server pages are on two seperate servers
which means that I cannot use MS Remote Scripting.Is there an alternate
approach in any scripting language ???
Any suggestions, tutorials , websites , code snippets will be
appreciated while i continue to research on this...

I'm trying to use a remote file for the purpose of setting the value of a single variable. It contains a single line of code:
var rev_date = "R10-03-07";
In the HTML, it is called like this:
<script language="javascript" src="http://some.domain.com/revdate.js"></script>
There is a function in the head:
function setRevdate() {
document.getElementById("revdate").innerHTML = rev_date;
}
In the Body:
<body onload="setRevdate();">
Then where I want to place the text:
<span id="revdate">--</span>
The problem is that the page loads and the onload event seems to happen before the rev_date string object is created and produces a "rev_date not defined" error. If I hit the browser refresh, however, everything works fine and the text is displayed between the span tags. It continues to work thereafter as long as the browser session is not destroyed.
How can I program this to force the browser to wait for the script to be read in and the variable initiated before calling the function?

I want to redirect all pages from one website to another. They will be permanent redirects, but I am looking for a way to make it look cool.
Is it possible (It does not HAVE to be a 301 redirect) that when someone goes to a page on the old website, they automatically go to the new website with a message explaining the transfer, and everything around the message goes grayscale until the user clicks ok...?

Does anyone know of a handy way to disable a user from downloading javascript when they save a page?
Here is my problem. I have javascript that disables right clicks on a page. However the user could just "save" the page to there desktop and remove the function that disables right clicks.
Anyone know of a good work around? I've heard of other complex ways, but I was looking for a simple solution.

We are downloading a few thousand rows of data for users to choose from
and need to speed up the operation. The data is related in four levels.
The current design allows the user to select the first level from about
20 choices and then the next level's choices are retrieved from the
server. This is taking about 4 seconds. We are required to make it
faster.
We need to be able to download all the data once and save it for use
any time this particular page is visited. The app is a support app and
the page will be used throughout the day. The obvious idea is to cache
it in a Java applet but we are not allowed to use applets. The other
idea is to embed it in JavaScript arrays but we have tried this and the
performance penalty is about the same and will be incurred on other
lookups on the page becuase the page reloads for these other lookups
(we are using WebLogic netui).
What we need is a cookie that is not submitted unless the page
explicitly sends it; that is, some data needs to be downloaded once per
session and remain in the browser memory/on the disk throughout the
session. It would be nice if we could write to a temp file or access a
heap - can we? Any ideas?

Has anyone tried sending web pages containing javascript to another user
also using Outlook Express?
Mine don't work on the other end - although I'm not sure if this is because
they don't have Javascript enabled in MS Explorer 6. I save the entire HTML file + script into my Stationery folder. Then I select Message/New Message Using [select stationery file]. Should it work? Say I sent this by email:
<html>
<head>
<script>
alert("Hi there!");
</script>
</head>
<body>
<p>Can you see the alert box? Let me know.</p>
</body>
</html>

And am putting it between <script type="text/javascript"> and </script> tags in the <body> section of my site. But, it only works in certain areas of the page.

I am remote scripting using javascript to an XML gateway, the XML file I get back changes state i.e. either the car registration number exists (and it includes certain fields in the XML) or it doesn't exist (and it doesn't include certain fields).
When my code tries to display the result I am getting the 'object required' error because I am trying to access an xml element which doesn't exist.
For example this line would break if the plate didnt exist but work perfectly if it did:
var fuel = response.getElementsByTagName('Fuel')[0].firstChild.data;
Is there anyway to stop it throwing an error if it doesn't exist and just set a regDoesntExist flag or something?

I have a PHP script that displays my online status and shows a window
if I am online, or doesn't show anything if I am offline.
I'd like to include the content of this remote PHP file inside a web
page using JS. I have created an xmlHttpRequest script to do that but
it doesn't work as expected... It should work just like the status.php
file, but instead, the content doesn't show up in IE, and in Opera, it
it stuck in the upper-left corner...

I am trying to use asp for remote validation instead of php. But it did not work. This is whatI tried.
$(document).ready(function() { var validator = $("#Member_Form").validate({
rules: { Member_Name: {
required: true,
minlength: 2,
remote: "users.asp"
}, },
messages: { Member_Name: {
required: "Enter a username",
minlength: jQuery.format("Enter at least {0} characters"),
remote: jQuery.format("{0} is already in use")
}, }});
Also how is the member name passed to the asp page. I tried reading it as query string. But it did not work.

I am writing a javascript based tool that other people can call on their webpages. I was wondering if I have gzip enabled on my server and they call my javascript file will it still have the benefits of gzip or will the fact it's being called remotely cause a problem.
The reason I ask is because the file is 54kb normally and 18kb when gzip is enabled on the server.

Basically i want to grab some data from the royal mail(UK) site, to use within a CMS, so the sales team can easily find the tracking info about a customers order.
Royal mail have recently allowed get requests which populates the track and trace form field and auto submits the page via a 302 redirect e.g.
royalmail.com/portal/rm/track?trackNumber=x
With X being the tracking number. Try: [URL]
(the links above should have www and http etc on but sitepoint won't allow to post them like this because of the spam filters)
So what i would like to do, if it is possible, is to use jquery to grab that page and possible grab a certain paragraph (in this case the first p of the class "track-right-box") so that the sales team don't have to go to the site every time they want to trace the order.
Now a figured i could use $.load or $.get in jquery to do this but firebug is throwing up the error: Access to restricted URI denied" code: "1012
Which i'm guessing is something to do with the security setting on firefox.
