View 4 RepliesI have a form and I need to validate a field against three rules:
1) The field need to be between 6 and 12 characters
2) It can only have letters, numbers, and the underscore
3) It cannot contain a space or other special characters
I want the validate to happen in real-time. I have the first rule working great. Here is the code for that:
var username = document.getElementById('registerUsername');
if((username.value.length < 6) || (username.value.length > 12))
{
document.getElementById('usernameValidate').innerHTML="Incorrect.";
[Code]....
I want to check if the user enters alphabet or numbers only in the
text box. If the user enters non-alphabet or non-numbers, I should pop
up a message and doesn't allow the user to do that. I am using regular
expression to do the checking. But it seems it always return false...
How can i validate string with alphanumeric, space, dash and dot in regular expression ?

View 4 Replies View Relatedwhy the string comparison test doesn't work in this javascript function? It works if you use just text between the currentItem div tags, but not when you use html for an image. I even tried to use iso characters instead of angle brackets, as in "<img src=expand.png></img>" and still no dice. Why not?
<html>
<head></head>
<body>
<script language="JavaScript">
function toggleValue()
{
if(document.getElementById("currentItem").innerHTML != "<img src=expand.png></img>")

I'm using the standard module pattern and the problem is once you set a private variable, trying to test that object independently becomes a nightmare as the next test is polluted by the actions of the previous.So, the options are to have some reset method (which is horrible), setters on everything (defeats the point) or delete object and re-load script (hideous).

I'm trying to debug my expression that matches an alphanumeric with any
number of dashes (including none), except at the ends and obviously
disallowing two or more consecutive dashes.
Here it is: /w+(-?w+)*/
Test cases that I expect to pass are failing:
"01234abcdef" true
"0123-412-8370" false (should've been "true")
"asdkfjakfj" true
"0-1" false (should've been "true")
"-" false
"--" false
"-ABC123" false
"00230-" false
"ABC-123" false (should've been "true")
"1-" false
"111223333" true
Would anyone lend a hand?

sort Alphanumeric and alphabets present in the same column.Numbers should be sorted first,and then the words with number in the beginning should follow it and then words in the sorting order.
View 3 Replies View RelatedI have used this script:Code:someString.replace(/[^A-Za-z0-9 .]/g, '')...many times to remove non-alphanumeric and non "." and " " characters but am having to re-think its use as I start working on non-American English languages for string replacement. The reason for this is that this RegExp also pulls out special characters such as "ó" and "ñ". I'm not certain, but I think it would also remove all double-byte characters such as various Asian-language words.Has anyone run into this problem and have they found a simple coding solution to catch all non-English special characters?
View 7 Replies View RelatedWe have been using the following js/regex to find and replace all non-alphanumeric characters apart from - and + outputString = outputString.replace(/[^w|^+|^-]*/g, "");
However it doesn't work entirely - it doesn't replace the ^ and | characters. I can't help but wonder if this is something to do with the ^ and | being used as meta-characters in the regex itself.
I've tried switching to use [W|^+|^-], but that replaces the - and +. I thought that possibly a lookahead assertion may be the answer, but I'm not very sure how to implement them.
I'm working on a script that will take the selected div and add an input to it.
If the div id="3" then when I alert it it works right but if the div id="post_3" then I get an alert of "object HTMLdivElement"
The javascript is simple(so far)
function create_reply_input(post_id){
alert(post_id);
}
And here's the php i'm using to populate the page with the posts
<li><a href='javascript:create_reply_input(post_$div_id);'>Reply</a></li>
JQuery seems to be giving an error when trying to pass an alphanumeric parameter like so:
[Code]...
when the above method is called, the error callback is called. However when I change the eventID parameter to a purely numeric value, it works fine and the success callback is called. I would like to pass an alphanumeric value to a server method and this doesnt seem to work.
The .find() method does not seem to match on input fields by using a class. The ti This problem seems to be only visible on input fields. The following is a demonstration of the issue:
Example at [url]
I want input in format "A-xxxx-xxx". where 'x' is any alphanumeric character.
View 1 Replies View RelatedI have the following code that test the target element of a mouse
movement to check if its and Image and the Parent is a Div element. It
works perfect in Fire Fox, however IE does not allow access to test the
target against instance of HTMLImageElement or the Div Element.
Is there a property that I can use to get the object type that will
return "image" or "div" or anthing else that I can use. The typeof
function only returns "object" which is totally useless in my
application.
DragObject.prototype.mouseMove = function(ev){
ev = ev || window.event;
var target = ev.target || ev.srcElement;
var dragObj = target.getAttribute('DragObj');
if ( target instanceof HTMLImageElement && target.parentNode
instanceof HTMLDivElement){
target = target.parentNode;
dragObj = target.getAttribute('DragObj');
}
}
I have Javascript on my site and will not work at all if JS is disabled.How do I notify my users that the pull down menus use javascript and will not work unless they turn it on?
View 2 Replies View RelatedI have a form on a page that the user fills out. When he's done and it's validated, I need the contents along with some other stuff to be printed before it's sent to the server. To accomplish this I'm using window.open on the Print button, then I intend to reference the fields from the page which opened it using the window.opener.formname.fieldname.value .
Problem is I have couple sets of radio buttons on the form that was filled out and I would like to print all the radio buttons showing the selected one so that the user acknowledges on the hard copy what his choices were.
If I was doing it server-side(ASP), I'd test the value of the incoming form value by executing a function, and I'd like to do it that way too, but I can't seem to figure out how to do that without putting <SCR IPT>function...</SCR IPT> tags with every radio button <INP UT> tag.
This also applies to where I'd like to write the values as HTML.
