Set Element Visibility Using Switch/Case?
Nov 19, 2010
So, I have a list of items that need to have a new preset list item appear based on what day it is. I have the date script working (to test, change the first case to some random date and change the third case to todays date - 10192010 - It will fire that document.write). What I need the cases to do though, is set the visibility of certain list items.
This is just an example, there will be around 20 list items in the final project. As you can see in the first two cases, I've tried a couple different routes to no avail.
The Code (class references are irrelevant to this example, they belong to the final project):
<html>
<head>
<script type="text/javascript" language="JavaScript">
/*

Is this sort of thing possible:
var X = 'Moe'
switch (X) {
case 'Curly'||'Moe'||'Larry':
alert('Found one of the Three Stooges');
case 'Chico'||'Harpo'||'Zeppo'||'Grouco'||'Gummo':
alert('Found one of the Marx Brothers');
default:
alert('No matches');
This gives 'No matches' unless I only put a single string in the 'case'
lines. I've just been using VB's Select Case which is a similar flow
control but which allows conditional arguments in the 'cases'. I just
wondered...
I realise you could put each set of names in an array and iterate
through each array, but that's a different issue.

I'm doing a bit of experimentation and would like a bit of advice if possible please.
In my switch statement I would like to use the || or operator, it works correctly it I set the case to 31, but if I try 1||31 it doesn't.code...

I am returning the present time - then using the .substr to remove all digits except the last two on the right (i.e effectively returning the value 32 from 65344532) I am then looping, subtracting 11 from that number until the value is less than 11. The intent being to then return the value from the appropriate matching array ID code...
The problem arises with evaluating two digit numbers beginning with zero - In cases where the last two numbers are greater than 09, the looping returns a 1 digit number for valuse less than 10, in cases where the last two digits begin with zero the loop will not begin. I have attempted to use the switch(n) to determine if any 01, 02, 03 ... etc exists but this is not evaluating correctly - is this due to using the date/time object and if so is there a good way to convert this to either a numeric or string datatype where the case can be evaluated correctly?

how to get this functionality going. I have a div name "footer". Within "footer" I have 4 links:
link1, link2, link3, link4
Is there anyway to write a function which will sense which link was clicked and then alert the id of that selected link. I have written the code but am not certain why isn't it working. here is my code.
$('#footer a').bind('click', function(){
//alert($(this).attr('id'));
var mId = $(this).attr('id');
switch(mId)

I know this does not work, but hopefully you can see what I am trying to do. Only the first value is tested, but I want all of them to be.
[Code]...
Pretend there are like 10 more cases with more numbers with them. Currently this will only text to see if x is 0 or 42. How do I get it to test for the other numbers?

I'm trying to figure out which elements of a document are visible as the user scrolls the Firefox browser. I haven't written the code yet but I think I should be able to do it by keeping track of the current display using the following properties:
window.content.scrollX, window.content.scrollY,
window.content.innerWidth, window.content.innerHeight. -- with these 4
I can determine which part of the document is visible.
Then for each element I can figure out its display position using, offsetWidth, offsetHeight, offsetTop, offsetLeft. This would entail traversing the DOM and perculating the offset values down to all the children.
While this would likely work, it seems inefficient. Do you know of any other ways to determine which elements are actually on the screen?

I found this little script and it works fine but the only thing is when the page first loads it displays the "This is foo" text. I would like it to not display the text until it is clicked. So instead of it displaying "This is foo" when the page loads I would like it to not display anything.
Here is the script:
Code:
<body>
<script type="text/javascript">
<!--
function toggle_visibility(id) {
var e = document.getElementById(id);
if(e.style.display == 'block')
e.style.display = 'none';
else
e.style.display = 'block';
}
//-->
</script>
<a href="#" onclick="toggle_visibility('foo');">Click here to toggle visibility of element #foo</a>
<div id="foo">This is foo</div>
</body>

In Bourne shell, you can do:
case ($x) in
foo*)
;;
*bar)
;;
esac
so that the first case matches any string starting with "foo", the
second any string ending in "bar", etc. In Tcl, you can:
switch -glob $x {
"foo*" {
}
"*bar" {
}
}
and accomplish the same thing. I'm struggling to do that in
JavaScript. switch seems to follow C semantics and do a full-length
match. And String.match() doesn't seem to do glob-style matching so I
can't do:
if ($x.match("foo*")) {
...
Is there a way to match on patterns in a JavaScript control structure?

So I have some code like:
if (document.Insurance.State.selectedIndex == 1)
{
ifIll();
}
else if (document.Insurance.State.selectedIndex == 2)
{
elseKan();
}
else if (document.Insurance.State.selectedIndex == 3)
{
elseInd();
}
I am trying to replace the if-else statements with case statement as
follows:
var index = document.Insurance.State.selectedIndex;
switch (index)
{
case 1:
ifIll()
break
case 2:
elseKan()
break
case 3: elseInd()
break
}
This code doesn't work ! Am I missing something here?

I'm working on developing an RSS/RDF/Atom Parser in JavaScript. I've already successfully implemented complete support for RSS 0.9x and 2.0. So far, so good. However, I've run into two minor problems. One is mentioned here, and one is in another post.
The issue that I'm coming across is the case-sensitivity of getElementsByTagName() when parsing standard RSS (XML) tags.
Danny Goodman's JavaScript Bible says that the tag name string that gets passed as the parameter in getElementsByTagName() is case-insensitive. However, this is speaking in terms of HTML and the HTML DOM. I'm working with XML, and getElementsByTagName is handling the XML tags as being case-sensitive.
Can someone suggest a way around this? Can a regular expression be used as the parameter? If so, what would the syntax be (as I'm not very familiar with regex)? For example, I want a <textinput> tag to be handled the same as <textInput> (which is the correct syntax).

I am writing some javascript code and just wanted to check if a case statement could have OR / AND. If yes, what would the syntax be like.
What I need is this:
switch (country) {
case "US" || "Canada":
//do something
break;
case "Australia" || "UK":
//do something
break;
}
I can alternatively use IF statement but was curious.

I'm experimenting with creating SVG dynamically and am finding that document.createElement is changing the case of the tags I input. This is breaking because, apparently SVG tags are case sensitive. For example, when I try to create a linear gradient element like so:var grad = document.createElement('linearGradient');what appears in the view source is:<lineargradient ...> (Note the lowercase "g")The tag doesn't work if the "G" is lowercase. Is there any way to specify in the <html> tag (or somewhere else) that the document should preserve tag case?

If I want to send something simple to the server and I don't need a response, instead of using AJAX, I use this:
<html>
<head>
<script type="text/javascript">
function sendToServer(someText) {
var fakeImg = new Image();
fakeImg.src = "http://localhost/takeparam.asp?param=" + escape(someText);
}
</script>
</head>
<body>
<input type="button" value="press me" onclick="sendToServer('baloney');" />
</body>
</html>
Is there anything inherently "wrong" with this? I know that it requires javascript enabled. As far as I can tell it will work on more platforms that AJAX so that should be a good thing, right?

I want to write a javascript that converts the (each) first character occuring after space in a string to lower case e.g abc def ghi jkl to abc Def Ghi Jkl
I have tried document.getElementByID and then checking for spaqce by putting the element in the Array but it does not work.

this is what im trying to do:
Code:
var field01 = document.getElementById("Field01").value;
field01[0] = field01[0].toUpperCase();
it doesnt work, the first letter of the field stays lower case BUT when I do this:
Code:
alert (field01[0].toUpperCase());
then it converts the first character to uppercase, well only in the alert box, the actual one still unchanged.
so i figure thats because it needs to be triggered somehow, it wont work by assigning it. i cant use it as return. are there any trigger methods that would just let me capitalize the first letter without any pop ups or anything?

I am putting together a simple edit in place script. For some reason, in order for for the editEffect function I've created to work I need to use the alert function as seen in the code below. I can't figure out the cause of the problem and I believe the root cause is also creating other problems - i.e. in the cancelEdit function the argument "targetElement" is not alerted, but it is successfully submitted as an argument to another function.
/* Edit in place javascript code */
function editLightOn(element){
element.style.backgroundColor = "#ffc";
}
function editLightOff(element){
element.style.backgroundColor = "#FFFFFF";
}
