JQuery :: Find() And Counting Non-empty Textareas On A Tab?
Dec 10, 2010
I need to count the non - empty fields on a JQuery tab. The following works to tally non-empty text fields and selects. How do I do the same for non-empty textareas?
I want to test if a input field is empty or not, if it is I don't want to execute the rest of the script. After googling I thought I might of found a solution but it doesn't appear to be working :( Even if the input field is empty my script still executes.The solution I found How do I test whether an element exists?The only thing I really add was:
if ($('#phone').length) before $('#search_customer').blur(function() to test the input field add_reservation.php
Just a quick one here I want a regular expression that tests a string to find out if not empty. I am currently using /^[a-zA-Z0-9]+$/ which allows all alphanumeric characters, however unfortunately does not allow white space. As I am trying to use the RE for a form name input and I don't wish to separate first and last name, I want to allow users to enter their full name including spaces. Can anyone tell me an RE that allows all alphanumeric characters and white space in a string but does not allow an empty string
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:
So far i managed to show/hide (the only) 1 textarea if an option is selected, using javascript. How can i show all textareas in form if an option is selected (lets say <option name="active">) and hide if option selected is name="passive"?
I'm trying to write a small little bookmarklet to insert some text into a textarea on a website I frequent. The first problem I ran into was that while the textarea I wanted to mess with was named, the form wasn't. To get around this I tried:
window.document.forms[0].comment_body.value which, for some reason, sometimes worked. But not every time. Then I found getElementsByName but I can't seem to get that working either. Here's my latest attempt:
javascript:function wlcauto() {elements = document.getElementsByName(comment_body);V = 'bla bla bla bla bla'elements.value = V;}wlcauto();void(null)
Is it possible to have text formatting inside textareas? I mean, can you show parts of text in a textarea as bold, italic, underlined, or such? If so, how's that work?
I'm trying to move data between two textareas. I have a script i found but it isn't doing exactly what i need it to do. I believe this would be an easy fix for somebody that knows more about javascript then i do (which is limited) Code:
There are other types of records but I am only interested in the ones which start with "|Note|". The field after "Pos:" will be compared to members of:
Basically i have a function that depending on which picture you click (one for "yes" and other for "no") it will make visible a textarea .
However right now if i click in "yes" it will display me the textarea for yes, and afterwards if i click "no" it will display both textareas, for yes and no. I want everytime i click on yes it will hide the "no" textarea and the same for when i click the "no" textarea, it will hide the "yes" textarea.
I am trying to add some sort of score system to my script, but I have no idea how to get this working. I have two files 1php and 1 javascript (which gets implemented in the php file)
What do I need?

I have some Javascript code that reads and sometimes sets the content of a textarea. I want this to be reasonably browser and platform independent. My question is, what characters should I expect to find at the end of a line? I suspect that I need to cope with either "" or""; can someone confirm?
Setting the content is more of a challenge. I don't want to have nasty browser detection to select what to use for newlines. Is there one newline pattern that is safe for all browsers?
I'm using a form where a user enters data in a textarea which is then copied to all other textareas on the page. Currently I have it working for 2 textareas using this code:
