How To Get / Check Size Of DIV

Jul 18, 2009

I am wondering if it's possible to run a bit of Javascript to check the size of a div with an assigned class. For example - I'm running a vBulletin forum and users can't have a signature above 400px in height. So, when the page renders, I would like to run a javascript condition that checks to see if the height exceeds 400px. If so, add style="overflow:hidden; height:400px" to the div.

How To Check The Input File Object File Size On Client Side?

Dec 20, 2004

I have a form with three Input File form objects in which the user can add image files. But I am worried about the problems these controls can lead, because to check the file size the server needs to receive the entire file, so serious problems may happen, for example:

1. Malicious user trying to collapse the website sending big files.

2. Users that have not seen the warning “Maximum size: 100 KB&#65533; for each image, and try to send three image files consisting in 1,5 MB each one. These users will have a bad experience waiting one hour or more to upload the images, and after that receive an alert saying “Oooops! Your image files are too big.&#65533; And also, web server will waste an important amount of resources. The same case with 100 users at the same time can be a nightmare!


I have been searching a way to check the file size on client side without having to force user to install anything, but I think that there isn’ t nothing to do with javascript. But I found an interesting PHP article that explains a way to do it with this server side language. The technique consists in:

“A hidden field (measured in bytes) that precede the file input field, and its value is the maximum filesize accepted. This is an advisory to the browser, PHP also checks it. This form element should always be used as it saves users the trouble of waiting for a big file being transferred only to find that it was too big and the transfer failed. Code:

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.

How To Get Window Size (not Viewport Size)

Apr 6, 2010

I'd have thought this would be easy but I've been looking for hours and all I can find is info on getting the viewport size, which is normally useful but not in my situation.

In this case I need the actual browser size, including the scrollbars, toolbars, status bars etc. to get an idea of browsers which aren't maximised/full screen and how big they are, and to calculate the amount of the screen taken up by toolbars etc too.

JQuery :: Uncheck And Check (re-check) A Radio Input On Page Load?

Oct 4, 2011

Here is the HTML: [URL] I'm trying to uncheck the selected radio button, then set the value to 1 (Yes), basically overwriting theinitialvalue to 1. I've looked at prop(), val(), and attr(), and just don't know where to start. Should I select $('#set_q157 input') or$('#set_q157 input:radio'), or each individual radio?

Do I need to each them, and check if its checked, then change its value, or is there a way to select all three inputs as just one radial button? It would also need to work if the input has not yet been checked.

Code To Check Quantity For Button, But It Will Not Check For Enter Key?

Nov 9, 2011

I am a php programmer and not a Javascript programmer and I am trying to help a friend out with his shopping cart. The original programmer (who wrote this years ago and is no longer around) has a button that looks up the quantities in the database for the submitted items, and then displays a prompt if you selected a quantity that is less than the minimum purchase amount.The issue is if the user enters a smaller amount than allowed and hits the enter key instead of the "Buy" button, it allows the order.how to use the current code to also check for an Enter key submission.I can handle the PHP and the db lookup for minimum quantities. Here is the page code and the Javascript code.

Code:
<a href="javascript:checkQuantity(document.form<?php echo $formCount; ?>,
<?php echo $row_rsProduct['lotQty']; ?>,

Check Before Posting The Form (including A Botdetect Check)?

Jul 18, 2009

I have an .asp page for my customers which does just accepts e-mail information and passes this information to another .asp page. But before passing the info, a javascript checks whether the entered e-mail does match some certain rules. Rule1: If any input has been made at all, Rule2: If an "@" sign is there, if the"." is there and so on. upon pressing the submit button, the first rule works but the second rule does not. Could not figure it out why.

[Code]...

It is the function control() which validates the e-mail field. But it just validates whether the e-mail has been entered or not. The second check (with the @ sign) is not being made.

URL Size

Nov 14, 2007

I have a page where multiple fields can be edited:

Name Age DOB
[name1] [age1] [dob1]
[name2] [age2] [dob2]
[name3] [age3] [dob3]
[name4] [age4] [dob4]
[name5] [age5] [dob5]

Where you can type in any of the fields etc and with one click all
these get updated by Javascript concatenating them into one variable,
escaped and passed through GET.

However I've discovered that when there are LOTS of entries, I have a
problem - I.E. seems to restrict the length of a URL to 2KB whereas FF
appears to be much higher.

Is there an alternative way to somehow send this data to my PHP
script? Would POST face the same restrictions and is it better/worse
than using GET for AJAX?
