## Change Image Upon Entering Data Into Textbox?

Jun 18, 2010

I'm interested in learning how to do this. What I'm doing is I'm making a social networking site linked to a game called Habbo, and for the registration page, once they put in their Habbo Username, I want to be able to load the image next to it. [URL]...

That is the link to the image. So basically, once they enter a value into the textbox, I want to be able to use that value to replace the [TEXTBOX.DATA] part from the above link and use that as an image.

## How Do I Determine The Number Of Lines Displayed In Browser?

Oct 2, 2005

If I had a webpage that displayed a database in tabular form, it would
be nice to know how many lines of text the browser could display
without scrolling, then have the cgi script output the appropriate
number of lines of data to fill the screen.

I've seen examples of how to get the browser window size in pixels, but
is there a way to determine the number of lines that are displayed?

## How Can I Count The Total Number Of Results Displayed?

Dec 2, 2002

I'm currently working on a javascript form validator and have run into a problem. The validator is used to make sure that the customer has entered a number in the quantity input box of the item they wish to purchase.

Code:

function validateRE(fieldToCheck, strRegExp, msg, min, max) {
if (!min) { min = 0 }
if (!max) { max = 100 }

for (i=0;i<15;i++)
{
if (fieldToCheck[i].value) {
var re_pattern = strRegExp;
if (!re_pattern.test(fieldToCheck[i].value) || fieldToCheck[i].value.length < min || fieldToCheck[i].value.length > max) {
fieldToCheck[i].focus();
fieldToCheck[i].select();
return false;
}
}
}
return true;
}
Used with:

Code:
<form method="post" action="../some_URL"
onsubmit="return (

validateRE(this.quantity, /^[1-9]{1}\$|^[0-9]{2,3}\$/,
'Please enter a Quantity.', 1, 3)

);">
The part in question is the red highlighted section.
The number of items that is under a specific product is generated dynamically and can range from 2-20. How can I get javascript to count the total number of items and run "for i=0;i<total number" instead so it is different for each product page?

## Exif Displayed For First Image Only?

Jan 24, 2010

I have a page that displays the exif info of an image. Unfortunately it only works for the first image.

After 2 seconds you should see 2 lines: Wait 5 seconds, then click me!

GPSLatitudetag: 51,48,7.572668393782384

Then after clicking the link this line should be added: GPSLatitudetag: 51,48,7.495423197492163

However I get only this: GPSLatitudetag:

No exif info for the second image. Why?

You can download a copy for local testing here.

## On Click Event Requireing Redirection And An Image To Be Displayed Before Redirect

Mar 15, 2010

I am not sure if the JS forum is the right place for this, but suspect the solution might be JS based.

I need to fire a 1x1 image when a user clicks on a link. I thought about the onclick event but the requirement has some tricky needs:

1. The 1x1 should load (preferably fully) before the redirection happens - the redirection ideally being the src attribution of the anchor tag itself.

2. The 1x1 should fire at the bottom of the page, not adjacent to the link clicked.

Is this possible?

## Open A Pdf By Entering Reference

Jul 23, 2005

We're in the process of re-writing the Intranet at work, and my javascript
knowledge could be written on the back of a post card. ;-)

Can any of you point me in the direction of some code that would enable a
form to open a specific pdf file? Details are below.

--------------------
All of our purchase orders are saved back to pdf files. Each pdf has the
prefix "PO_" followed by the po reference, then the file extension ".pdf".
For example, our file would be called "PO_12345M.pdf".
Each set of files is archived into years (folders are called 2003, 2004,
2005 etc.) so it will probably need a drop down box to select year, unless
it can search through all the folders.

The visitor should only need to enter the PO reference, and the code puts
the "PO_" and the ".pdf" on the end of it, and hey presto Acrobat opens with
the PO, or you get an error dialog if the file cannot be found.
--------------------

## Parameters Not Entering Function?

Jul 20, 2005

I keep getting a runtime error stating that this
object. I've rewritten the Function everyway I could think of, and
couldn't find any thread examples of my problem.

Here is my Function;

<Script language="JavaScript">
<!--//hide

}

</script>

This calls the Function;

<input type="button" value="Make This My Dealer"
name="button">

When the code breaks and I bring up Microsoft Debugger it shows a
value in the parameter.

## Create A Pop-up Window Upon Entering A Website?

Jan 7, 2010

I'm wanting to create a pop-up window that shows upon entering on the website with two buttons that have different functions.

I'm wanting the first button, when clicked, stops the message from appearing again.
-Similar to the "do not show again" option that uses cookies from this thread.. [URL] the second button, when clicked, redirects the user to a URL

Is it as simple as using the code from the thread above and some simple javascript buttons?

## Prevent User From Entering Mistakes

Jul 3, 2009

<script type = "text/javascript">

function testfield() {
var un = document.getElementById("dir").value;
if (!/^(/ftp/nas)/i.test(un)) {
alert ("Invalid starting characters - must be /ftp/nas");
return false;
[Code]...

I have a code like above which doesn't allow the user to proceed with out starting the field with a "/ftp/nas" which should be the starting of a path. Is there any way to make it disabled and the user only can enter the rest of the path. for eg: user1 has directory path like /ftp/nas/user1/help

so when this user enters his path, on the field "/ftp/nas" should always be available and the user has to only enter the rest of the path. and the user is allowed to enter only / (// is not allowed) and [A-Za-z] in the field. this is just to secure the application from typing mistakes.

## Entering Language Version Gives Syntax Error In IE8

Jul 15, 2010

Basically, the script is an onMouseover slideshow which works fine. The problem is that in internet explorer, it says there is a syntax error relating to the javascript code. (this doesn't appear on chrome or firefox) here is the code:

Code:
<script>
<script language="JavaScript1.1">
var myimages=new Array()
</script>

basically, by putting the script language here, IE8 is saying there is a syntax error! removing it stops the error but stops the script from working. What can I do here? If I put it in an external .js file instead (right now it is in the head of the HTML page) will this solve the problem?

## Calendar Script For Entering Dates In Form?

May 6, 2011

I downloaded a calendar script that allows a user to just click on the date and have it populate the form input field- the problem is it lets you enter dates previous to today. I would like it so it could not enter any dates less than today.

Problem is, I know nothing about javascript. I am less than a noobie.

Would some kind soul have a look and see if it would be possible to do and show me what to do.

The code is below. There is also a css file which I did not include.

Code:
function positionInfo(object) {
var p_elm = object;
this.getElementLeft = getElementLeft;
function getElementLeft() {

## JQuery :: Number Behind In Pic Count (1/10) - Slideshow Never Counts The First Image

Feb 26, 2011

I am trying to create an image gallery, with two buttons next and previous which work fine, and with a counter like (1/10) etc. I've got it to work but for some reason the slideshow never counts the first image so therefore is always one image behind. Somebody pointed out to me it is probably that the array starts at 0 and something else at 1
