Compare String In Array

Jun 12, 2007

I need some advice regarding wrote a javascript function.
The function purpose is to check the variable "selectedSeat",

for e.g if the selectedSeat value is

var selectedSeat = "A:01|A:03|A:05|B:01|B:02|B:03";
var selectedArray = selectedSeat.split("|");

because row A is not in sequence , i will display alert box to
user,but row B is in sequence is ok.

Main purpose of function is check if the row is in the sequence.
I have been cracking my head about this , anyone have suggestion is
much appreciated.

Compare String With Numbers In Javascript

Jul 23, 2005

if (123 > 33) will return true

and

if ("123" > 33) will return true

So my question is, if the above behaviors are the same?? If string is
a number, and compare with another number, it will be the same behavior as compare 2 numbers?

In this case, it is comparing 2 strings that are numbers, so they are
string comparisons here. correct?

if ("123" > "33") will return true

In this case, "33a" is not a number, that's why when it compare with
another number, it always return false. correct?

if ("33a" > 33) will return false...

InnerHTML String Compare Not Working?

Jan 22, 2011

why the string comparison test doesn't work in this javascript function? It works if you use just text between the currentItem div tags, but not when you use html for an image. I even tried to use iso characters instead of angle brackets, as in "<img src=expand.png></img>" and still no dice. Why not?

Is it because of the way innerHTML manages html and it's not really a string? Is it because it doesn't have all the tags and some other representation?

Code:
<html>
<head></head>
<body>

[Code].....

XmlDom - Compare A String To A .nodeValue It Always Fails, Even If They Are Same?

Apr 13, 2011

I'm still pretty new to javascript and dom, but have been coding with other languages for a while.When I try to compare a string to a .nodeValue it always fails, even if they are same. From what I've read typecasting is automatic in javascript or is this incorrect? For instance

var myGreet = "Hello";
var myFrag = myXML.lastChild.firstChild.firstChild.childNodes[0].nodeValue; returns Hello
if(myGreet == myFrag){ always returns false
alert(myFrag);
}

Compare An Array To A Variable?

Mar 16, 2009

I'm trying to compare an array to a variable and see if it has the same value then output the second part of the array:

<script language="javascript">
var photoCaptionID0 = "13006";
var photoCaptionID1 = "24018";
var photoCaptionID2 = "13002";

[Code]....

So using this example. If any of the first section in the array captionID (24001, 13001, etc) has the same value as photoCaptionID0, then print the second part of captionID (Item 1, Item 2, etc).

Finding Place In List - Script - Read Through An Array Of Words And Compare Another Word

Feb 7, 2009

What I am trying to do is build a script that will read through an array of words and compare another word to the list to find where it would be placed alphabetically; between which two words would my word go.

Here is what I have come up with so far which doesn't work with words shorter than the shortest word in my list, or words spelled like the shortest word in my list except having a few more characters, plus more various issues.

Example: My list

If I use keywords "apex," or "as", this script fails.

What can I do to fix my code...

Process String Formatted As Array Into Array?

Mar 18, 2011

I get strings in this format:

([{"result":"-1","message":"Error","target":""},{"result":"-2","message":"Access Denied","target":""}])

this string will evaluate to a 2D array if I do this:var array = eval(string);But eval is not very safe.Is there a way to achieve the same effect (turn that string into 2d array) without using eval function?And I have no control over what string I am given, so will have to process this kind of a string =Right now I am thinking of writing a custom function which will split the string and then split again etc, but is there already something that can do this job?

Using A String As A Pointer To An Array?

Apr 26, 2011

So i've written up the code to do a lightbox esque overlay image gallery. everything is working smooth and fine. The only concern is that I have the following:

lets say that I have a page that has multiple galleries. Obviously I would have to make each literal array with the gallery data different names, ex:

var _gallery1 = {
'images': [
{ 'id' : 1, 'src' : "" }
]

[Code]....

obviously "galVariable" would be undefined... as i'm trying to get "_gallery2.images" but trying to use "galVariable" to point to "_gallery2"

I'm familiar with solving a problem like this in PHP, not so much javascript. is there a JS function that can be used to ensure that it's using whatever "galVariable" equals to, and then that array's content is? Or is there a different way to go on about this.

Updating String/array Items

Oct 16, 2007

I'm not entirely familiar with the norms and standard libraries of
JavaScript so if the answer to this is yesterday's news, please ignore.

I'm trying to write a simple text formatting function to make headings
proper case -- i.e. first letter of words capitalized.

I first tried this...

function inProperCase(s)
{
var result, i, k;
i = 0; result = s.toLowerCase();
while ((k = result.indexOf(' ', i)) -1) {
if (k - i 0) {
result[i] = result[i].toUpperCase();
}
i = k + 1;
}
if (result.length - i 1) {
result[i] = result[i].toUpperCase();
}
return result;
}

...but it didn't work. To my amazement, you cannot set a character in a
string by accessing that character with an index, like so:

s[i] = ch;

Must be because JavaScript strings are "Immutable" or "EtchedInStone" or
something. (Just kidding, no flames, please. I'm sure it is more
efficient.)

The only thing I could come up with was this (with some details, like the
"compound" while predicate, modified into a more readable form after being
called a "C-bigot" by a friend :)) which seems pretty heavy-handed with all
the string slicing and concatting:

function inProperCase(s)
{
var result = s.toLowerCase(),
i = 0, k = result.indexOf(' ', i);
while (k -1) {
if (k - i 0) {
result = result.substring(0, i) +
result[i].toUpperCase() +
result.substring(i+1, result.length);
}
i = k + 1;
k = result.indexOf(' ', i);
}
if (result.length - i 1) {
result = result.substring(0, i) +
result[i].toUpperCase() +
result.substring(i+1, result.length);
}
return result;
}

You call this as...

inProperCase(" madam i'm adam ");

...and you get...

" Madam I'm Adam "

Any suggestions for making this a bit more elegant?

BTW You may point me to a "library" with a super-efficient implementation
of this function, but that is not the point. My issue is, how do we update
single characters in a string (or single items in an array) in JavaScript?
Is it something like...

s.wouldYouCareToUpdateThisChar(i, ch); // :D (just kidding, calm
down...)

-or-

s.setCharAt(i, ch); ...
