Correct Syntax For Getting Objects?

Dec 21, 2004

I'm used to just using getElementById to look stuff up in my own scripts but I'm doing an assignment and it would not look good to put id's everywhere to modify a html page when there are already name attributes in the elements.

In this page I can't refer to the Family Name input box using document.form1.familyName for some reason. Is it because it's inside a table after the form is opened? What syntax should I be using? Code:

Getting The Correct Parseflow Syntax?

Feb 20, 2011

I�m just writing a simple dynamic counter.

<form name="eqform">
<input name="ButtonLectureplus" value="+1" type="button" onclick="lectureplus(0.75)">
<input name="TextLecture" type="text" size="30" maxlength="30" readonly>


This works in a way that "number" isn�t used and 1 is added repeatedly. 2). Function:

function lectureplus(number)
{document.eqform.TextLecture.value = document.eqform.TextLecture.value + number;}

This doesn�t work because he shows me "0,750,750,75 .... " (and also "+=0.75" shows the same result)

alert (typeof document.eqform.TextLecture.value + number); show me "string0.75"

I tried to use parsefloat() to force "document.eqform.TextLecture.value" be a number but can not find the right syntax to make it work.

"parsefloat(document.eqform.TextLecture.value)" doesn�t work

Event Listeners Won't Use Correct Objects / What To Fix It?

Sep 27, 2011

I feel like I must be missing something simple but I can't put my finger on it...

I'm moderately new to JS (programmed in other languages though) and am working on a Google Maps project.

This piece of code should show an alert of the region's name when a map polygon is clicked. Instead, no matter what polygon is clicked, it only does the name for the LAST iterated placemark. code...

What am I missing? What would be a better way of handling this?

Get Correct Width Of TD?

Jul 9, 2009

I'm working on recreating a paper form as accurately as possible in XHTML. I can't keep my sanity with that man DIVs, so I'm using nested tables.

In most fields (TDs) I have a label and a text box, and I'd like to have the text box fit the width of the TD as accurately as possible, without going on to another line. As far as I've heard, the only way to do this is using JS to get the width of the TD and the label, and then adjust the width of the text box to fit.

I'm using FireFox 3.0.11 for development. For some reason, the width of the TDs is being reported incorrectly. I've tried .width, .style.width, .offsetWidth, .clientWidth and .scrollWidth. They all agree within a few pixels, but are horribly incorrect. My current screen resolution is 1400x1050, and I've taken a screenshot and measured that to confirm - the actual width of the TD is approx. 1130 pixels, but it's being reported by all of those JS functions as +/- 865 px.

None of the tables or TDs have widths defined, it's all just automatic sizing. The only width/size defined at all is an overall div with 2% margins on each side.

Correct Nesting Of UL, OL, LI Elements

Feb 16, 2007

I'm looking for opinion/facts/arguments on the correct nesting of UL,
OL, & LI elements.

For example, this is what I want (unordered list):

* Item 1
* Item 2
* Item 3
* Item 3a
* Item 3b
* Item 3c
* Item 4

Now, in my markup, I can do (A) or (B), and they both work.

<!-- Markup (A) -->
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
<li>Item 3a</li>
<li>Item 3b</li>
<li>Item 3c</li>
<li>Item 4</li>

<!-- Markup (B) -->
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3
<li>Item 3a</li>
<li>Item 3b</li>
<li>Item 3c</li>
<li>Item 4</li>

Now, I prefer, and think that Markup A, is the better representation
of the data... but... I can't find a spec, that dictates which one is
"officially" correct... (due in part to the fact that in old HTML
days, the closing tags were not needed... thus the confusion as to
"where" that closing tag goes, when nesting)

This gets very interesting in the JS/CSS world, trying to deal with

If I generate Markup A, then get a reference to the LI element for
"Item 3", called say... foo then I ask for foo.followingSibling, in
Mozilla, I get as expected, the UL element, but in IE, I get the LI
for "Item 4"... IE "moves" the UL node, to the .lastChild position of
the preceding LI element.

So, here's the questions...

1.) Which method (by vote, spec or whatever) is correct/better?
Method A or B?

2.) Based on (1), is the IE implementation a Bug, or a Feature?

3.) If you want to style the sub items, what CSS would you use for
Method A, or B... or does it matter?

PS I don't expect a unanimous answer to any of these, I'm just trying
to get a feel for how everyone else interprets how Nested Lists are
"supposed" to work.

Return Message If First Value Is Correct?

Jun 21, 2010

I'm trying to figure out how to make this work and I'm stumped. I wrote this code:

<script type=text/javascript>
function firstfunction();
document.form1.outputstate.value="this is a number";

I'm trying to doing something really simple but I can't seem to make it work. I'm trying have the textarea display a certain message depending on if the first input box says a certain word or number. So like in the code, if the user types "55" or "never" in the first box, then the second box should say a certain message. Then I used the else statement so that if "55" or "never" is not entered, then the second box says nothing. If you can spot my error or suggest a different way of going about writing the code

Not Returning Correct Display.

I've created a script that should display a certain image based on the day of the week and the time of the day. After uploading the page to the site I receive no errors, however I'm not getting the display I should be seeing. It always returns the image from the final "else" statement. I'm thinking the problem is that I have two "&&" operators in each "if" statement, and I don't have the proper syntax, or perhaps I'm not writing it properly. Code:

Using Javascript To Determine The Correct URL

Nov 16, 2005

I want to create a link to an email conference which is on 2 servers. Some users will only be registered on server1 and others will be registered on server2. however I don't know which users are on which server.

Is it possible to create some kind of JavaScript function which attempts to open a link to server1 and then if this fails default to server2. It would be far more user friendly.
