Auto Size Textarea Rows

Jul 20, 2004

I have a bunch of dynamically generated (PHP) text area tags, and I want to put buttons next to them that automatically change their number of rows to the number of rows of text that appear in the text area.

So if there are 10 lines of text (wrapped, with an occasional line break), I want my javascript function to figure that out, and then set the appropriate value.

Here's what I came up with so far. taID is passed into the function as the ID tag value of the text area.

Code:

document.getElementById(taID).rows = parseInt(document.getElementById(taID).value.length/document.getElementById(taID).cols);
The problem (I think) is that when it encounters a line break, it only counts that as one character, whereas in theory I want it to count as the remainder of the line.

Can't figure out how to pull this off, though. Any ideas?

JQuery :: JqModal - Auto-size And Auto-center The Modal On The Page?

Aug 29, 2009

Using the very basic jqModal example, isn't it supposed to auto size and auto center the modal on the page? I placed a table that was wider than the modal's default settings and it's off the page and does not create scroll bars on the page to see the hidden section of the modal.

The default class is

Now, I know I can change the width of the modal but what about the positioning?

Auto-resizing - Proportional Background Image With Minimum Size Preset

Aug 12, 2011

I'm close, but the issue is that if the window is opened at a size that is SMALLER than the original image, it wont scale down to the smaller size until i first make the window bigger, THEN size it down smaller. The image itself is big (its fashion photography so it needs to be high res) and the js sets the minimum width at 1070. Id like to have the image as big as possible and then on page load automatically drop down to as low as 1070px if the window size is small. Here is the js:

Accessibility: Possible To Determine Browser-chosen Point Size Of A Relative Font-size?

Jul 23, 2005

All my font-sizes are set as relative sizes in CSS (large, medium, small,
x-small, etc). Let's say something is set in CSS to be xx-large, but a
visually impaired user wants it displayed even bigger. Can a script
determine an element's absolute size, *as it is being rendered by the
browser*, and then increment the element's font-size in absolute terms?

Resizing DIV - Makeweb Page That Adapts To Size Of Your Browser Size When Maximized

Jul 19, 2010

I'm attempting to make a web page that adapts to the size of your browser size when it maximized. Because I'm only 15 I'm not such a great programmer or coder. I've done my best with the resources I have though (Fluent in Lua and a natural ability to pick languages syntax up quickly)

Here is what I have so far, it doesn't work and it is starting to puzzle me. As it seems correct as I look at it. I'm sorry if this question show my ignorance. I try my best to hide it.

Some of it is Copy pasted from sources on Google. But only for educational purposes, I learn off reading, examining and testing out snippets.

I'm basically trying to get the max size of the window and resize the div accordingly.

Limit File Size Or Request Size

May 27, 2010

I developed a web application and it is working fine, except for one issue. The application includes uploading files from a JSP to my servlet, and the issue is that i would like to have a limit for the uploaded files on the client side (before actually uploading it).

I investigated alot and found some ways like changing my JSPs to PHPs, which is not feasable for my application. I would also like to add that using the Flash component ("<object>") for uploading is not feasable also at this time. Using ActiveX does not work also (for some security issues in javascript, it can not access the system information, also ActiveX works only on IE).

I would like to add that I have my application running on Oracle application Server, JSPs for displaying the forms, MultiPart Java API for getting the form input values and files to my servlet and everything is developed in JAVA.

Either by limiting the file size or the limiting the whole request size sent to the servlet.
