I am trying to find a way to search to see if there is a specific file located in the current directory on the server. 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.

Simple enough, checks to see if the image is accessible, I used it to check to see if my server had restarted yet, modify as you wish!
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.

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 1 Replies View RelatedUsing Javascript I need to figure out how to check if a URL actually exists. The problem is that the Javascript file may not always be there so I have I have to check every time I need it.
AJAX is not an option AND its has to cross browser compatible.
*NOTE The URL will always be pointing to a Javascript File

I'm trying the figure out how to check if a id exists.
I have tried this;
if(document.getElementById("theID")
Then do this
But that doesn't seem to work.
All I want to do is if it doesn't exist then don't run the function.
How can I check if a function exists in any of the scripts on my page?
I prefer if it can work for both Javascript & VBScript.
How do I check if an object exists in Javascript?
EG:
if (document.getElementById("product").value == null)
{
prodValue = "";
}
else
{
prodValue = document.getElementById("product").value;

This gives me an 'object required' error...
I'm using ccs3PIE with my site. What I want to do is check if a DOM element has a css property like border-radius and then add a class to it.
The problem I'm having is that I don't know how to check for the css property. I've been searching for it for a couple of hours now and I can't find anything that seems to work.
I found out how you can check if an array value exists but I can't seem to get it to work with the options array for some reason.
how I can find out if a certain select value exists?
I'm not entirely sure this is possible. I hope it is, and it doesn't seem to far-fetched or impossible.
With JS, how would one go about checking if a user has DivX Web Player installed?
Usually people put in code within the embed, so if it the player doesn't load, it would have the message behind stating the fact. However I haven't seen this used at all with DivX, instead, you see pop-up boxes, whether installed or not, stating "Don't have DivX Web Player? Get it here for windows or mac"
I find this extremely annoying, and would never want such informalities on my website.
If I have a form like so:
<form>
<input type="text" />
</form>
[code]....
One holds the form and the other the php Query process.Im using a small piece of javascript to POST the value to my php Query process scriptbut im finding it difficult to display a result by fading in a div based on the query response.For example if i type in a tag and the tag already exists i want the php to check the table and the return a faeIN div to say it "already exists" otherwise fadeIN a div to say "Tag inserted into database"But i also am using a little more JS to clear the input field value as well.All this is done without reloading the page.So basically if the tag "People" exists in the MYSQL table then i want the div #i2 to fade in and say "Already exists!"My code is below:The HTML
<form method="post">
<div>
<strong>Keyword: </strong> <input type="input" id="tag" name="tag"/> <input type="button" id="send"

In my page templates, which are included on every page, I have some javascript that is necessary to create some effects. However a couple of pages do not require the javascript, and because of this the page elements are not present. How would I add a check to ensure the element ID exists before running the javascript code? In other words, here's the code in question:
Code:
var thevar = document.getElementById("theid").getElementsByTagName("LI");
Is there a conditional that can be wrapped around that to prevent the javascript code from running if no elements named "theid" exist?
I would like to check if a function exists before define it. Does this make sense:

I have a jquery dialog with a registration form in it. My problem is: I want to check if the username (input) already exists in the database, if so I want to return a error.
I know I have to use AJAX... but how?
Explanation of my form:
(this is a dialog)
My form:
Username: testuser ERROR: username already exists
Password:
Name:
[Code]....
Let me explain the issue which I'm facing with an example.My URL is http://localhost/~gaurav/dstreetmantra/register.php.One of the anchor tags in my navigation bar is <a href="register.php">Register</a>.The code needs to be able to check whether the value in this very anchor tag's href attribute is present in the URL.If it is present, the word 'Register' register would be highlighted. If not, some other link would be highlighted.As I said, I'm doing this for the navigation bar. This way, it'll check which of the links' 'href' value is present in the URL, and thus highlight that link.I'm assuming this can be done using Regex, but I do not know how to use it.
