JavaScript - $10 For Solution

I am a govt. employee wanting to make a multi-user database. This is a replacement for the current solution:

1. Single-user Excel sheet on a shared network folder.

Here are my design limits:

1. The system uses Windows XP only.
2. I do not have communication with the network admins.
3. I will never have permission to install servers anywhere. They are forbidden.
4. I do not have permission to install any software on any computer.
5. My group only has access to one shared network folder.

I've brainstormed some solutions, including:

A. Marrying a VB Application with SQLite, with the SQLite file sitting in the shared folder.

B. Using how to use SharePoint to develop my application.

C. Using Microsoft Access as a client-side GUI which connects to another .mdb on the shared folder.

D. Using Internet Explorer with Javascript and ADO ActiveX Objects to manipulate records in a .mdb on the shared folder.

I choose D. Choice A is out because I can not install any software development tools. B may not work for me because my database is heirarchical in nature and I want more control over the GUI. Same reason for C, and Access is a little micky-mouse.

Amazingly, the security settings on IE allow the creation of ActiveX objects through Javascript. I can also develop with javascript because I have Wordpad. To test the code I can simply run it by launching the HTML. This allows users to open the same HTML file in the shared folder instead of distributing front-ends.

The javascript must all be client-side, including all data manipulation. However, I am not concerned about security issues because only our group will be using the system, and all traffic is already contained within Navy networks. So I don't care if I use window.location for storing variables since it works for this case.

Does anyone have anything to say about this? I'm looking for pointers, gotchas, guidelines, and any other, better solutions. Thanks.

Hi,

javascript method downloadUrl() is very very slow at chrome.

means, i am not able to see the data from mysql server at chrome browser..

But this works fine at IE.

Pls suggest me with some alternative javascript methods..

Hi,

Normally when i try to put a form in a html page i use the
Code:

<form action="http://www.site.com/test.php" method="post">

and so on with the respective input (Something i learn over here)

Today i was trying to create a html box whith the purpose of submiting to a external site but the problem i got is that the external site doesn't use the Code:

<form>

tag to submit and uses javascript in an onclick event. Is there any way i can still submit?

Note: I tried an iframe 0 to load up the site and the respective scripts and emulate the submition in the top page but didn't work out.

Thanks for all the help...

but I just can't figure it out. I have trawled the net for a solution and tried many different things that I have seen but still no luck. Maybe the answer is staring me right in the face and I just can't see it.

The code it executing the first time but as the setTimeout tries to start the second loop I get an error 'box is not defined'.

Any suggestions and explanations of what I am doing wrong much appreciated!

Code:

function expand(box) {

var box = document.getElementById(box);
var originalHeight = parseInt(box.style.height);
var inc = 5;

newHeight = (originalHeight + inc);
box.style.height = newHeight + "px";

int = setTimeout('expand(box)',100); }

I was trying to find a way to preload images using javascript or PHP or anything that would work - specifically I wanted a way to preload all images from a directory AND its sub-directories.

Well, there are solutions out there and some are pretty complex.

In the end I chose to do a simple thing which works well for particular image-heavy pages. It is so easy I am wondering why it isn't more often mentioned.

OK, it's simply including on a chosen "lead-in" page some almost invisible inline frames (1 px x 1px) of the image-heavy pages you want to preload the images from:

Code:

<iframe name="I1" src="index1.html" marginwidth="1" marginheight="1" scrolling="no" border="0" frameborder="0" width="1" height="1">
</iframe>
<iframe name="I2" src="index1b.html" marginwidth="1" marginheight="1" scrolling="no" border="0" frameborder="0" width="1" height="1">
</iframe>
etc.

Sure, you have to stay long enough on the lead-in page, but even if you don't, its a help.

Here is my solution in action: http://maraboni.aapress.com.au/html/...y/gallery.html

(my site went down just as I posted! but it'll be on in a short while, I hope!)

You can see that I have used a nice bouncing ball loader routine (pace.js) top right to partially alert the user to what is going on, but it is not essential.

Without the inline frames, clicking on the nav links at the top of the page will usually result in a less than optimum visual experience and a necessary page reload of the image-heavy pages.

I can't see any downside. Can anyone?
