Writing A Function That Returns A String That Outputs A Branched Bulleted?

Jul 30, 2010

How would you go about writing a function that returns a string that outputs a branched bulleted list using <ul> and <li> tags of all the html elements in a page? The html elements don't all have id's or names, so I cannot reference them directly. I would like to do it recursively so that I can grab all the elements, not just those two or three levels deep.

Writing Recursive Function - Return All The Permutations Of A Given String

Oct 29, 2009

I'm trying to return all the permutations of a given string, so I wrote the following recursive function:

The problem is, I'm not getting all the permutations, and I don't know why.

For example, if string="bindle", the output I get is:

And then the function stops.

String.Length Function Returns Undefined?

Mar 27, 2011

When I run the following code, the .Length function returns "undefined."

var strTest = 'test';
alert(strTest.Length);

Using the typeof function, I know that JS is treating the variable as a string.

Writing String Value To A Separate Iframe Using Onmouseclick

Sep 19, 2010

I am currently trying to create a simple form based web-page (uploaded here [URL] that creates a query for a WMS (Web Map Service).

The page consists of about 10 different forms, which are all put together in a (string) variable named "compiledQuery" in a function named "compileRequest" which is activated via a button. I would like to print out this variable on the page so that the users can see the query for themselves. After doing some research I came to the conclusion that the best way to do this would be via an iframe (I do not want to use a pop-up). The function I use to do this is:

function printRequest()
{
var query_frame = document.getElementById('frame_compiled');
query_frame.document.write(compiledQuery);
}
"frame_compiled" is the name of my iframe:
<iframe name="frame_compiled" width="400" height="125">
</iframe>

I know that "compiledQuery" has been assigned a value (I used an alert with the value). Hence, I also know that the "prinRequest"-function works on principle... However, it seems as if I am having problem with retrieving the name of the iframe to the function (I tried doing an alert with the value, it was returned as null).

So, I suppose my question is this: How do I properly retrieve the value of the iframe, and am I on the right way using document.write to show the value of "compiledQuery" to the users? Or should I use another way of doing this completely?

JQuery :: Serialize And IE 7 And 8 - Returns An Empty String

Dec 21, 2011

I have a form with an id "modClassForm" when I try:$("#modClassForm").serialize() it returns an empty string ("") When I get the action attribute it's right so it is the form I was expecting. When I do the following:

$("#modClassForm input").val()

it returns "retret" (the contents of the input element in that form). So what is doing this? The only thing I can think of is that this form is loaded from ajax and then placed in the page using the .html(htmlString) method which is rather core to my design. This works in a whole lot of other browsers (IE 9, FF 6-8, Chrome 13-15 and Safari 5). So I know I could try to serialize the fields myself, but the form content has two modes and I'd have to construct a fairly large string and I'm not sure about encoding. Is there any other way to make serialize work? Some way to get it to recognize the contents of the form?

JQuery :: Function Returns The Code Inside The Function?

Aug 29, 2011

I am having a strange problem with a javascript function that does not return the value but returns the code inside the function. My best guess is that I am incorrectly calling the function hasLandedOn()and jquery is interpeting it. Why is this happening? I highlighted the parts in red.-Tom ReeseThe following is returned NOT the variable imageName.

function hasLandedOn(){
var selectorLoc = $("#selector").offset();
var imageName = "";

Writing A ToFixed Function

Jul 20, 2007

I'm not that familiar with javascript, and I am trying to write a
toFixed function.

The function takes two arguments, the number and the number of decimal
places we're interested in.

If the number of decimal places is negative, it's interpreted as the
number of significant digits.

Thus:

toFix(12345.6789,2) -12345.67
toFix(12345.6789,0) -12345
toFix(12345.6789,-2) -12000

I've hacked up a solution that so far works on all tested browsers for
the first 2 cases.

It's the last one I'm having trouble with... How do I get only the
significant digits?

It has to work for all of the following cases:
toFix(12345.6789,-2) -12000
toFix(12345.6789,-5) -12345
toFix(12345.6789,-7) -12345.67

Writing Function Output Values?

Jan 20, 2009

I've got a glitch somewhere and it's not obvious to me. Maybe someone can spot it.My problem is that the functions seem to return values but don't display them like they should. I'm testing returned values with a function called sayvalue(item). But when I test "DelTimeCode" the function returns "[Object]". I don't understand. I get returned values from DelTime and DelTitle.My approach is to select a radio button option, return a delivery title and a delivery price from the appropriate functions then write the information. I think I'm close. Any suggestions or observations of an error in my code?I have the following VARIABLES and FUNCTIONS:

<head>
var AmtSV;
var DelTimeCode="";

Use Of Speech Marks When Writing Function To HTML

Jan 13, 2009

I've been using the document.write function to loop through some xml and print the data within a HTMl table. I thought it would be useful to add a hyperlink to the table row, so I thought the best way to do this would to create a function (called popup), which takes an id as a parameter.

The problem with this, is that when writeing using the onClick, the speech marks seem to all get messed up.

Code:

onclick='popup('"+mailID+"')'

I'm 99% sure it's just the speech marks, i'm just not sure of the right combination, and it's doing my head in

If someone could even point me in the right direction, even the proper name as to what this is called would be great, as googleing it is proving to be a nightmare!

Here's the whole section of code if it's more useful:

Code:

var mailID = x[i].getElementsByTagName("mailid")[0].childNodes[0].nodeValue;
if (r == "unread") { //email is unread
document.write("<tr onclick='popup('"+mailID+"')' title='test'>"); } else { //else is read, so add colour

Time Function - Output Returns Nothing

Feb 21, 2010

I am trying to taking this embedded script
Code:
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
var strDay;
if ((now.getDate() == 1) || (now.getDate() != 11) && (now.getDate() % 10 == 1)) // Correction for 11th and 1st/21st/31st
strDay = "st ";
else if ((now.getDate() == 2) || (now.getDate() != 12) && (now.getDate() % 10 == 2)) // Correction for 12th and 2nd/22nd/32nd
strDay = "nd ";
else if ((now.getDate() == 3) || (now.getDate() != 13) && (now.getDate() % 10 == 3)) // Correction for 13th and 3rd/23rd/33rd
strDay = "rd ";
else
strDay = "th ";
document.write(dayName[now.getDay()] .....
// End -->
</script>
and turn it into a function called time.

XHTML Source
Code:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "[URL]">
<html xmlns="[URL]" xml:lang="en">

Code:
function time() {
var strDay;

strDay = "nd "; .....

But when I do the out put returns nothing. Why this might be. I initially thought that I had the formattingsyntax wrong for the function it self but this doesn't seem to be. [URL]

RotateSwitch Function - Value Incorrectly Always Returns One

Sep 4, 2010

I have four images:
Code:
<div class="main_view">
<div class="window">
<div class="image_reel">
<a href="#"><img src="images/1.png" alt="" /></a>
<a href="#"><img src="images/2.png" alt="" /></a>
<a href="#"><img src="images/3.png" alt="" /></a>
<a href="#"><img src="images/4.png" alt="" /></a>
</div></div>

When rotateSwitch() is called on launch, it assigns the second image to the $active variable (given that the first image was given active class in beginning of script). Then rotate() function is called and we get 1 (2-1) and then multiply by imageWidth. Now the second time the rotateSwitch() function is called, we should get 2 (3-1), but the alert still only returns 1 and the fourth time it only returns 1 as well:
Code:
$(document).ready(function(){
$(".paging").show();
$(".image_reel img:first").addClass('active');
var imageWidth = $(".window").width();
var imageSum = $(".image_reel img").size();
var imageReelWidth = imageWidth * imageSum;

$(".image_reel").css({'width' : imageReelWidth});
rotate = function(){
var triggerId = $active.attr('src').substring(7,8);
var image_reelPosition = (triggerId - 1) * imageWidth;
alert('the value is ' + triggerId);
$(".image_reel img").removeClass("active");
$active.addClass("active");

$(".image_reel").animate({
left: -image_reelPosition
}, 500);
};
rotateSwitch = function(){
play = setInterval(function(){
$active = $(".image_reel img.active").next();
if ($active.length === 0){
$active = $('.image_reel img:first');
}
rotate();
}, 7000);
};
rotateSwitch();
});

Execution Of Function Bar - Returns Undefined

Dec 12, 2011

Suppose we have following javascript codes: Case 1.
var foo = function (){
var x = "hello";
var bar = function () {
alert(x);
} return bar;
} var bar_ref= foo();
document.write(bar_ref()); // it pops up "hello" and print-outs "undefined".

If we modified above code slightly, shown as follow: Case 2.
var foo = function (){
var x = "hello";
var bar = function () {
alert(x);
} return bar();
} var bar_ref= foo();
document.write(bar_ref()); // it only pops up "hello".

As you can see, Case 2 modified the return value from "return bar" to "return bar()," which won't cause the "undefined" output. To me, it looks like when the JS interpreter executes the line "bar_ref();" it triggers the execution of function "foo", besides both "return bar" and "return bar()" do the same job which is to execute function body of "bar".

The only difference is that after the execution of function bar, its function body does not exist anymore, so when the interpreter executes the line "return bar;" it follows the function identifier "bar" and ends up with "undefined". This is why the Case 1 gives us "undefined", but I am not quite clear about why the Case 2 can trace down to the function body of "bar". Do you have any ideas about such difference outputs?
