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.

Building SVG Document Using DOM Interface Inside HTML Document

Mar 17, 2007

Normally an SVG document is loaded/parsed/interpreted inside an HTML
document using an 'object' (or 'embed') element, although there are
supposedly other ways too. The problem is, the SVG document must be
static this way.

I want to use the DOM interface to build SVG dynamically inside an HTML
document. I am guessing I can build it inside HTML within an 'object' (or
maybe 'iframe'?) element.

My intentions/goals:

In Javascript, I construct an object 'embedSVG' which has properties and
methods for creating valid SVG elements and setting their attributes and
attribute values.

During construction, the SVG document is created with its root element.
During debugging in FF 2.0 (I'll work on an MSIE-compatible format later),
I am using the Mozilla DOM Inspector and comparing nodes when the
'object' element is loading a valid external SVG document, and when I am
appending the child representing the SVG document created by the DOM
functions.

However the child node (#document) does not specify 'svg' as the root
element, but instead 'HTML'. Something is not working.

Here is the relevant code in 'ScriptTest.html' which is the HTML in which
the SVG is supposed to be embedded. Below it is the relevant code for
'svglib.js' which is supposed to contain code for building the SVG
dynamically.

What this code is supposed to do is load the HTML page and execute the
anonymous script, and draw a navy blue-bordered yellow rectangle on a
blank page. This is similar to the example in the SVG 1.1 W3C
Recommendation on page 202 of the 719-page PDF.

I am getting an exception when embedSVG object placeInHTML() method is
called: NS_ERROR_DOM_HIERARCHY_REQUEST_ERR. I find in DOM Inspector in
spite of or after the exception that a document is placed as a child of
the object element, but it is HTML, with a default 'head', 'title',
'body' elements placed.

Where am I blowing it?

Javascript Document History - Is It Possible To Know The Previously Viewed Document?

Jul 24, 2001

Determine what the previous page was that the user was viewing, even if the user arrived at my site by through the use of a browser function (history, location bar, refresh, etc.). Is this possible?

I'm not wuite sure how document.history functions - what degree of privacy is given to the user and to what extent can web pages get URLs from the user's history?

Document But When Using The Object Onmousemove It Seems To Run The Code Even If The Mouse Is Still Over Then Document

Dec 6, 2010

I am trying to make a function run if the mouse is moved over the document but when using the object onmousemove it seems to run the code even if the mouse is still over then document, how can I make it so if the mouse is over the document but isn't moving then don't run the code but once the mouse moves run the code? This is the code I made to handle the mouse move collections.

[Code]..

But with this code it runs even when the user doesn't move their mouse and the notification box pops up every second as the code seems to think a still mouse is a moving mouse.

I was thinking about having a run once system but that would mean if the mouse moves it runs once and then if the mouse moves again the code will not run as it has already ran before.

Document.onkeyPRESS || Document.onkeyDOWN Dynamically?

Oct 26, 2007

I want to switch a big function from a document.onkeydown = function to a document.onkeypress = function, or vice versa depeding on the type of browser.

However it is quite a big function so it's pretty much out of the question to have it appear in full twice.

Any ideas how to change the target event (onkeydown/onkeypress) without writing the whole function twice?

Building The Document In A New Window Entirely With Document.write

Document.write() - Trap Changes Done To The Document Object

Jun 5, 2006

I have been searching for a way to trap changes done to the document object (mainly by the function document.write();).

Example of code that doesn't work:

function myFunction() {
ed.document.onchange = doFunction(document.body.innerHTML);
ed.document.open();
ed.document.write('Hello');
ed.document.close();
}

function do_function(body) {
alert(body);
}

It only fires when the page loads, not when I change the text. You are free to use any event that works, but i think onchange was the one to fit this problem. The alert will write the initialpage, but will never write the tekst 'Hello' that is the new change.

Any javagurus out there know a solution to pick up any fired events triggered by document.write();

Line Using Document.write() And Document.writeln()?

Jul 16, 2010

I am trying to write a bunch of text onto a new document using document.write() and somehow need to format it to include line breaks.

For example:
Code JavaScript:
document.write(Line 1);
document.write(Line 2);

I have tried including and it does not work. I have also tried document.writeln() and that also does not work. From what I have found on the Internet, one (if not both) of those methods should have worked.

Using Document.Writeln After Document Is Parsed

Oct 28, 2009

I have three files:

HTML file (default.htm)

Code:
<body>
THE QUICK BROWN FOX JUMPED OVER THE LAZY OLD DOG
<script type="text/javascript" src="testing.js"></script>

[Code]....

When I run the above files the original text on default.htm is wiped and replaced by the document.writeln text in test2.js. What I wanted to happen was for this text to be added to the default.htm page (and not wipe what was already there). I believe this is because the htm file has already parsed.

I know people say you should use innerHTML and not document.write or document.writeln. Unfortunately, I have no control over the contents of the first file (default.htm) or the third file (test2.js) but the content in test2.js will always be in either document.write or document.writeln format. So I cannot use innerHTML.

My problem is how can I (from within the second file, testing.js) ensure that the page is not parsed before the third file has finished.

Using Document.createElementNS Instead Of Document.write

Jul 31, 2003

I need to eliminate the document.write for this bit of code

copyright=new Date();
update=copyright.getFullYear();

document.write("Copyright &copy; 2001-"+ update + "&nbsp;" );

var showtext = "Tecknetix";
var mailpart1 = "webmaster";
var mailpart2 = "tecknetix.com";

document.write("<a title='email tecknetix' class='hov' href=" + "mail" + "to:" + mailpart1 + "@" + mailpart2 + ">" + showtext + "</a><br />");
The reason is now I'm using <meta http-equiv="Content-Type" content="application/xhtml+xml; charset=utf-8" /> with xhmtl 1.1

Since I've changed the MIME type to application/xhtml+xml from text/html the document.write is invalid now.

Here is a page with a demo on it so you can see how they changed document.write("<link rel="stylesheet" ...") around.

http://www.xml.com/lpt/a/2003/03/19/dive-into-xml.html

I think only the Moz1.4 supports application/xhtml+xml

You can see it on my 4 page site. http://www.tecknetix.com/

In IE6 you can read the copyright notice but in Mozilla you can't. But in you go to view > page info in Moz - you can see application/xhtml+xml as the type.

Document.location.href Or Document.URL

Dec 18, 2002

Which is the better option to use when dynamically loading a page?

document.location.href = "newpage.html"

or

document.URL = "newpage.html"

My book says that Netscape depreciated document.location.href in favour of document.URL, but yahoo are using document.location.href. Also, is there a good online reference (up-to-date) of the DOM which includes stuff like this?
