maxlength

I got a simple input field which has a maxlength="2" attribute. The code looks like this below: <input id="txtLoginName" maxlength="2"> It works fine on most Android devices. However, on the HTC One M7, it does not work. On this device, it just allows me to enter as many characters as I want. Any suggestion? I think it should be a device specific issue so far. Thanks in advance. Try this one: var $input = $('input') $input.keyup(function(e) { var max = 5; if ($input.val().length > max) { $input.val($input.val().substr(0, max)); } }); I've noticed this issue on a couple of projects. I think

See title​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​ Michael Aaron Safyan Short Answer: No Long Answer: Yes, it has to be small enough that it will fit in memory, but otherwise no, not really. If there is a builtin limit (I don't believe there is) it is so huge you'd be really hard-pressed to reach it. Actually, you got me really curious, so I created the following Python program to generate code: #! /usr/bin/env python2.6 import sys; cppcode=""" #include <iostream> #include <cstdlib> int main(int argc, char* argv[]) { int %s = 0; return 0; } """ def longvarname(n): str="x"; for i in xrange

First things first: I'm storing multiple domains to a database, after I've converted each and every domain name to it's IDNA version. What I need to know the maximum length such an IDNA-converted domain name can have so I can define the database field's max length. Known fact: Now, I know the maximum number of characters in a domain name (including any subdomains) is 255 characters. Where I lost it: That's easy at first glance, but... does this mean regular ascii characters of international characters (think UTF-8 encoding)? To give you an example: The domain "müller.de" has 9 characters when

I want to store PHP's microtime as my timestamp in MySQL. I've been told it's best to store it in DECIMAL , but I can't find an ideal size. Does anyone know what the maximum size microtime(true) returns, so I can put that as my data type length? Should I choose variable DECIMAL length? tl;dr. Use microtime(false) and store the results in a MySQL bigint as millionths of seconds. Otherwise you have to learn all about floating point arithmetic, which is a big fat hairball. The PHP microtime function grabs the Unix timestamp (currently about hex 50eb7c00 or decimal 1,357,609,984) from one system

I am using TinyMCE for <textarea> . My requirement is to limit the character size to 2000 and also to show the remaining characters somewhere below the tool bar. I somehow managed to get the characters number; now I am stuck with displaying the remaining characters and prevent from exceeding limit. Here is my TinyMCE code tinyMCE.init({ // General options mode : "textareas", theme : "simple", plugins : "autolink,lists,pagebreak,style,table,save,advhr,advimage, advlink,emotions,media,noneditable,visualchars,nonbreaking, xhtmlxtras,template", // Theme options theme_advanced_buttons1 : "bold

Why can not I create a deep path whose characters in path is more than 255 in NTFS File System? It seems a limits of FAT32, but also exist in NTFS? Can anyone provide some documents? Many Thanks! The 260 character limitation is not a limitation of the file system, but of the Win32 API. Win32 defines MAX_PATH as 260 which is what the API is using to check the length of the path passed into functions like FileCreate, FileOpen, etc. (which are used by .NET in the BCL). However, you can bypass the Win32 rules and create paths up to 32K characters. Basically you need to use the "\\?\C:

I want to find the longest VARCHAR in a specific column of a SQL Server table. Here's an example: ID = INT IDENTITY DESC = VARCHAR(5000) ID | Desc ---|----- 1 | a 2 | aaa 3 | aa What's the SQL to return 3? Since the longest value is 3 characters? aweis Use the built-in functions for length and max on the description column: SELECT MAX(LEN(DESC)) FROM table_name; Note that if your table is very large, there can be performance issues. for mysql its length not len SELECT MAX(LENGTH(Desc)) FROM table_name Watch out!! If there's spaces they will not be considered by the LEN method in T-SQL. Don't
