I'm new to javascript and PHP and I am wondering if there is a method or function to capture a 404 error in the event a particular html file cannot be found. I want to redirect that error to another page or design the code to send me an email telling me what page was selected and not found. In other languages I can trap such an error and respond to it.

I won't lie to you. I'm trying to get data from html source from a 3rd
party website. I'm NOT interested in stealing code,hacking,sending
spam or anything sinister like that. I just want the content that is
displayed but I need to get it automatically via VB. It's only
publicly available price information but I don't think the website
wants everyone to be scraping their info into a database.
Apart from the base URL, the site concerned navigates solely through
javascript functions and session variables. I suppose what I'm asking
is, is there anything out there that tells me (the syntax) of what my
browser is actually sending to a website when I click a javascript
toolbar/button/dropdown within IE.
I have designed a site. It's working properly in locally.Now I want to insert a special javascript on my home page.The job of that special javascript is, makes some errors in the site when site is going to publish on internet.

I am having troubles finding a way to use JavaScript to see if a file exists before an ASP file upload script runs. Is there an Exists check for JavaScript? I thought I found an ObjectName.Exists but doing this did not work.

If a folder contains file1.txt or file2.txt and depending on which file is in that folder change a certain javascript variable. What it comes down to is, is there a way to search for specific files on the server and limit that to the current directory/folder.

I sell didjeridoos and handdrums.
I was hoping to create small html program for each drum, somthing like this....
<script>
thisdrum=new Image()
thisdrum src=drum001.gif
price=100
rim=12
height=24
</script>
<script src=createpage.js>
</script>
and saved as drum000 to drum999
Now I need a function included in the creatpage.js, that checks if a file exists,(eg drum000.html) if it does, go there, if it doesn't, try drum001.html
any suggestions on how I could go about it?

This is probably going to show how new I am to jQueryI have a form with an input text field for entering a URL. The user will most likely paste a URL and I want to automatically verify it's status once the user leaves the field. Basically just make sure the page loads ok.I've found dozens of topics that are close to this, but my lack of jQuery skills is hindering me from adapting any of them properly.

View 6 Replies View RelatedThis is a follow up with a new question from a post I did last week. [Code]... I have an experimental website where I have music recordings. url removed When you open the site, each page uses a piano keyboard graphic to navigate between pages. If you click on a key that says "Jukebox" it will open a small window and continuously play tunes. The way the jukebox works basically is, when you click the jukebox key it calls an html file which contains the information needed to play the first song. When that song is finished it calls another html file with the information to play the second song and so on. Each html file contains an embedded Windows Media Player in it.
I would like to give visitors the option to use the QuickTime player. So I can have one key in the keyboard graphic that say “Jukebox – for Windows Media Players” and then another key in the graphic that would say “Jukebox – for QuickTime players”. I would like to use both keys to call the same html file. So, in the file I would like to:
1. Determine which key was pressed in the graphic. (how to send a parameter from the keyboard graphic file indicating which key was pressed) 2. With that parameter I would then like to invoke the appropriate player. (how to receive that parameter)

I call methods in a Java applet with javascript code like this:
document.myApplet.methodName();
This works great when the applet has loaded (the JVM has started and dowloaded all the jars) but it fails if the applet hasn't loaded yet, at which point it gives an error:
Quote:
Error: Object doesn't support this property or method
Is there a way to determine that the applet is loaded or not so that I can use it in an if statement? For instance, like so:
Code:
if (isAppletLoaded()) {
document.myApplet.methodName();
}
I tried
Code:
document.myApplet == null
but that didn't work.

I have a JS file on site A which needs a few parameters from a short text file on site B. Since crossing domain boundaries in JS is problematic, the way I do it is that the JS actually opens an intermediate PHP file on site A which redirects to the destination page in site B. Here's how it goes:

The problem is that this takes a long time. I would really like to speed this up. For example - I thought of using a direct IP address, so that there won't be any need a DNS server (using
Code...
) but this would expose me to hackers as it would make my Hostgator username visible. According to HG support the above format is the only way to access my subsite via direct IP.
Any ideas on how to speed this up, either by bypassing DNS (but without exposing username) or by offering another way of reading data across sites?
