View 1 Replies View RelatedI think I have what is a simple question: I would like a checkbox to be checked if it is not already when a user types in the text area beside it. Form layout is demo'd below.
<table>
<tr>
<td><input type="checkbox" name="box[1]" value = "x"></td>
<td><textarea name="area[1]">
The subject says it all. Is that possible with jQuery?I would like to have a script that goes through a webpage when it loads and replaces all instances of [text] in the html with <a href="text.html">text</a>.
View 4 Replies View Relatedthe script at the bottom appends a text area with info onclick [URL] I wanted to know if it's possible to have a function (possible within the existing one?) that replaces text as well.
Something like this format would be perfect for what I'm tring to do:
<a href="#" onclick = "check('Replace this text', 'With this in the textarea')">Click Me to replace</a><br/>

If you've used the Google Gmail spell checker you know that it
'changes' the text area to another type of control that lets them show
hyperlinks for the incorrect words. How does Google change the
textarea? And what do they change it to? I know it should be pretty
simple, I just have no clue because I'm fairly new to DHTML. Any
examples would be greatly appreciated.
Here's a script to check if there's typed in a message into a textarea (at least I think it is...) :

And here's the form :

I would like to disable a feature on my site if someone is in a textarea or input text field. Yet I can't seem to figure out how to check for this... Could someone give me an example of how I can determine if a user does not have a text input or textarea selected? Can't seem to get anything I found via google working.
View 2 Replies View RelatedI'm using the following code (simplified version) to call a Json file, parse it and on each iteration, create a div with an ID of "tab". I'm using this with jQuery UI .tab() to create a listing with entries which have three tabs. Anyhow, the principle seems to work except that when I examine what's happening behind the scenes using Firefox console, I see that each href in the html code produced is causing the Json function to re-fire using the href as it's url target.

How would i change back to the default length of textarea?
I have this comment area that after clicking submit i will append the new comment in the list of comments through ajax... i got one problem though, everything is working perfectly well except for the textarea that won't change back to it's default size...
EXAMPLE:
The problem is that the textareawon't change back to it's default size // let's say that the default size is rows=3
I think this is just a dumb question, I'm missing some basic logic here about jquery "grammar".
I'm trying to do an image swap on hover that checks to be sure the thumbnail is not the active thumbnail. So mouseover, it swaps. Mouseout, swaps back, unless the thumb has been clicked.
Here's a snippet of the code that doesn't work:
How do I check that _li is not ".active" and replace the src if it isn't?
what code I can add to a webform textarea box that will replace all instances of " " with "\n" when a user pastes in JavaScript like this:
[Code]....
The form is on a .php page. The form posts via a .cgi script. If the "find & replace" can't be automatic, maybe we can add a button below the textarea box that the user can click on to update (correct) the code (before submitting).
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.
I want a function that when you check on a check box another check box appears.

<script type="text/javascript">
var str="Welcome to Microsoft! Microsoft Microsoft";
var stringToBeFound = 'Microsoft'
var ReplaceString = 'site'
document.write(str.replace(stringToBeFound , ReplaceString ));

My problem is im trying to use string.replace that is not case sensitive and replace every string found. I could use regular expression with it but my stringToBeFound is a dynamic variable im getting it from my database
i have a list of checkboxes, the number of checkboxes is dynamic. All the checkboxes have same name. i am trying to get the length of selected checkboxes.
<input type=checkbox name=name1 value=1>
<input type=checkbox name=name1 value=2>
........ get dynamically.
when i try to get the length in javascript like document.form.name1.length, it works fine if number of checkboxes selected are more than 1, but not for 1.
I have a code that I got from a tutorial website. The goal is when someone clicks the first check box with the value of yes then the two other sets of check boxes will autmatically be checked for no.
The issue is their are three sets of 2 check boxes each.
So here is my code code I am trying to use

Here is my form code

So Ideally when a representative clicks that the customer has three services (clicks the Yes checkbox) all the other checkboxes will default to No.

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']; ?>,

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.

What is a good way to switch a number at the end of a string?Im trying to change the value 0 to value 1 at the end of a URL when a button is clicked. (And vise-versa)So if I have this:<a class="important_ajax" href="projects/important_ajax/0"></a>Them the part here should be simple but im unsure of a good way to do this easily:
$(".important_ajax").click(function() {
$obj = $(this); // So I can use THIS object inside of other objects.
$url = $obj.attr('href'); // This is the URL: projects/important_ajax/0
[code]....
I am using an online e-commerce hosting solution and they wont let me get certain stored data because they have full control.Anyhow the link on the page looks like this:[URL]How do I match and then get the full value of the url. The important value is 12.
View 2 Replies View RelatedI have a page with dozens of anchored links. When you click on the link, the appropriate div becomes visible. Each div contains an image. Because each DIV has a large image associated with it, it takes entirely too long for the page to load. I would like to set the IMG SRC inside of the div when they click. Each anchor href is the exact same name as the image to be loaded - so #dali would contain dali.jpg. How dow I pass the HREF minus the hash mark (#)? This is as far as I've gotten:
$("a").click(function() {
var whichDiv = $(this).attr("href");
$(whichDiv).attr("src", "images/art/" + whichDiv + ".jpg");
});
