isset equivalent in javascript to find palindrome

I created a script in PHP to find a palindrome, but when I try to do the same in JavaScript, then it is not working as expected. It's not just a matter of checking if the string that is reversed matches, but any order of the string has to be checked as well.
In other words, "mom" should return as true, "mmo" should return as true, "omm" should return as true, etc..., which is what the PHP script does, but the JS script below doesn't even work for the first iteration for the string "mom"
The following is the PHP script:
<?php
function is_palindrom($str) {
$str_array = str_split($str);
$count = array();
foreach ($str_array as $key) {
if(isset($count[$key])) {
$count[$key]++;
} else {
$count[$key] = 1;
}
}
$odd_counter = 0;
foreach ($count as $key => $val) {
if(($val % 2) == 1) {
$odd_counter++;
}
}
return $odd_counter <= 1;
}
echo is_palindrom('mom') ? "true" : "false";
The following is what I have tried in JS:
var count = [];
var strArr = [];
var oddCounter = 0;
var foreach_1 = function(item, index) {
console.log("count[index]: " + count[index]);
if (typeof count[index] !== "undefined") {
count[index]++;
} else {
count[index] = 1;
}
};
var foreach_2 = function(item, index) {
console.log("item: " + item + " item % 2: " + eval(item % 2));
if (eval(item % 2) == 1) {
oddCounter++;
}
console.log("oddCounter: " + oddCounter);
return oddCounter <= 1;
};
var isPalindrom = function(str) {
strArr = str.split("");
console.log(strArr);
strArr.forEach(foreach_1);
console.log(count);
count.forEach(foreach_2);
};
I believe it is failing where I try to replicate isset in javascript, with the following code:
if (typeof count[index] !== "undefined") {
As a result, I have tried to write my own isset function, but still the same result, it is not working:
var isset = function(obj) {
if (typeof obj === "undefined" || obj === null) {
return false;
} else {
return true;
}
};
With the following function being called:
if (isset(count[index])) {
count[index]++;
} else {
count[index] = 1;
}
As usual, any help would be appreciated and thanks in advance
BTW, it's killing me that I cannot remember the word for several revisions or iterations of something - I know that it starts with "re"

My attempt:
let p1 = `No 'x' in Nixon.`
let p2 = `Was it a car or a cat I saw?`
let p3 = `A man, a plan, a canal, Panama!`
function is_palindrome (str) {
const normalize = str => str.replace(/[.,:;`'"!?\/#$%\^&\*{}=\-_~()\s]/g, '').toLowerCase()
const reverse = str => [...str].reverse().join('')
return normalize(str) === reverse(normalize(str))
? true
: false
}
console.log(is_palindrome(p1))
console.log(is_palindrome(p2))
console.log(is_palindrome(p3))

First, thank you for all the comments.
Second, I ran a var_dump on the count array in the PHP file and this was the result:
array (size=2)
'm' => int 2
'o' => int 1
Which lead me to understand that count in js has to be an object for this work and I would have to create indexes of the object, depending on the string entered.
One thing lead to another and a complete re-write, but it works, along with a spell checker - see link at the bottom for complete code:
var count = {};
var strArr = [];
var oddCounter = 0;
var objKeys = [];
var splitString;
var reverseArray;
var joinArray;
var url = "test-spelling.php";
var someRes = "";
var mForN = function(obj, strArr) {
for (var y = 0; y < strArr.length; y++) {
// console.log("obj[strArr[" + y + "]]: " + obj[strArr[y]]);
if (isset(obj[strArr[y]])) {
obj[strArr[y]]++;
} else {
obj[strArr[y]] = 1;
}
}
return obj;
};
var mForN_2 = function(obj, objKeys) {
for (var z = 0; z < objKeys.length; z++) {
/* console.log(
"obj[objKeys[z]]: " +
obj[objKeys[z]] +
" obj[objKeys[z]] % 2: " +
eval(obj[objKeys[z]] % 2)
); */
if (eval(obj[objKeys[z]] % 2) == 1) {
oddCounter++;
}
// console.log("oddCounter: " + oddCounter);
}
return oddCounter <= 1;
};
var isset = function(obj) {
if (typeof obj === "undefined" || obj === null) {
return false;
} else {
return true;
}
};
var isPalindrom = function(str) {
// reverse original string
splitString = str.split("");
reverseArray = splitString.reverse();
joinArray = reverseArray.join("");
var checking = checkSpellingOfStr(str);
if (str == joinArray) {
strArr = str.split("");
// console.log("strArr: " + strArr);
objKeys = makeObjKeys(count, strArr);
// console.log("filled count before mForN: " + JSON.stringify(count));
// create array of keys in the count object
objKeys = Object.keys(count);
// console.log("objKeys: " + objKeys);
count = mForN(count, strArr);
// console.log("count after mForN: " + JSON.stringify(count));
return mForN_2(count, objKeys);
} else {
return 0;
}
};
var makeObjKeys = function(obj, arr) {
for (var x = 0; x < arr.length; x++) {
obj[arr[x]] = null;
}
return obj;
};
var checkSpellingOfStr = function(someStr) {
var formData = {
someWord: someStr
};
$.ajax({
type: "GET",
url: url,
data: formData,
success: function(result) {
if (!$.trim(result)) {
} else {
console.log(result);
$("#checkSpelling").html(result);
}
}
});
};
Start everything with the following call:
isPalindrom("mom") ? demoP.innerHTML = "is pal" : demoP.innerHTML = "is not pal";
In my example, I have a form and I listen for a button click as follows:
var palindromeTxt = document.getElementById("palindromeTxt").value;
var btn = document.getElementById("button");
btn.addEventListener("click", function (event) {
isPalindrom(palindromeTxt) ? demoP.innerHTML = "is pal" : demoP.innerHTML = "is not pal";
});
The following is the php for spell check:
<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
if(!empty($_REQUEST['someWord']))
{
$someWord = $_REQUEST['someWord'];
}
$pspell_link = pspell_new("en");
if (pspell_check($pspell_link, $someWord)) {
echo trim($someWord) . " is a recognized word in the English language";
} else {
echo "Your word is either misspelled or that is not a recognized word";
}
You will need pspell installed on your server, as well as adding extension=pspell.so to your php.ini
This is what I did, to get it running locally on my mac:
cd /Users/username/Downloads/php-5.6.2/ext/pspell
/usr/local/bin/phpize
./configure --with-php-config=/usr/local/php5-5.6.2-20141102-094039/bin/php-config --with-pspell=/opt/local/
make
cp ./modules/* /usr/local/php5-5.6.2-20141102-094039/lib/php/extensions/no-debug-non-zts-20131226
sudo apachectl restart
check your phpinfo file and you should see the following:

TypeError in Javascript

function url_info()
{
var url_val=document.getElementsByClassName("spc-tab");
var current_s=0;
for(var i=0;i<url_val.length;i++)
{
var url_class=url_val[i].className.split(" ");
if(url_class[1]!=null)
{
if(url_class[1]=="selected")
{
current_s=i;
break;
}
}
}
var temp_1=url_val[current_s].text; //**Error here**
return(temp_1);
}
In this function url_info i am getting the TypeError But i don't know why?? .... as My var current_s is defined within the scope and integer...

why write this much of code when one line can do:
function url_info() {
var temp_1 = "";
var url_val = document.querySelector(".spc-tab.selected");
temp_1 = url_val[0].text > 0 ? url_val[0].text : temp_1;
return (temp_1);
}
and second, you don't require to convert your class name to string then split. You just can access them through classlist. Then use contains.
function url_info() {
var url_val = document.getElementsByClassName("spc-tab");
var current_s = 0;
for (var i = 0; i < url_val.length; i++) {
var isSelected = url_val[i].classList.contains("selected");
if (isSelected) {
current_s = i;
break;
}
}
var temp_1 = url_val[current_s].text;
return (temp_1);
}

Is there a javascript library that does spreadsheet calculations without the UI

I am working on a project that needs an excel like calculation engine in the browser. But, it doesn't need the grid UI.
Currently, I am able to do it by hiding the 'div' element of Handsontable. But, it isn't elegant. It is also a bit slow.
Is there a client side spreadsheet calculation library in javascript that does something like this?
x = [ [1, 2, "=A1+B1"],
[2, "=SUM(A1,A2"),3] ];
y = CalculateJS(x);
##############
y: [[1, 2, 3],
[2,3,3]]

I'm not aware of any (although I haven't really looked), but if you wish to implement your own, you could do something along these lines (heavily unoptimized, no error checking):
functions = {
SUM: function(args) {
var result = 0;
for (var i = 0; i < args.length; i++) {
result += parseInt(args[i]);
}
return result;
}
};
function get_cell(position) {
// This function returns the value of a cell at `position`
}
function parse_cell(position) {
cell = get_cell(position);
if (cell.length < 1 || cell[0] !== '=')
return cell;
return parse_token(cell.slice(1));
}
function parse_token(tok) {
tok = tok.trim();
if (tok.indexOf("(") < 0)
return parse_cell(tok);
var name = tok.slice(0, tok.indexOf("("));
if (!(name in functions)) {
return 0; // something better than this?
}
var arguments_tok = tok.slice(tok.indexOf("(") + 1);
var arguments = [];
while (true) {
var arg_end = arguments_tok.indexOf(",");
if (arg_end < 0) {
arg_end = arguments_tok.lastIndexOf(")");
if (arg_end < 0)
break;
}
if (arguments_tok.indexOf("(") >= 0 && (arguments_tok.indexOf("(") < arg_end)) {
var paren_amt = 1;
arg_end = arguments_tok.indexOf("(") + 1;
var end_tok = arguments_tok.slice(arguments_tok.indexOf("(") + 1);
while (true) {
if (paren_amt < 1) {
var last_index = end_tok.indexOf(",");
if (last_index < 0)
last_index = end_tok.indexOf(")");
arg_end += last_index;
end_tok = end_tok.slice(last_index);
break;
}
if (end_tok.indexOf("(") > 0 && (end_tok.indexOf("(") < end_tok.indexOf(")"))) {
paren_amt++;
arg_end += end_tok.indexOf("(") + 1;
end_tok = end_tok.slice(end_tok.indexOf("(") + 1);
} else {
arg_end += end_tok.indexOf(")") + 1;
end_tok = end_tok.slice(end_tok.indexOf(")") + 1);
paren_amt--;
}
}
}
arguments.push(parse_token(arguments_tok.slice(0, arg_end)));
arguments_tok = arguments_tok.slice(arg_end + 1);
}
return functions[name](arguments);
}
Hopefully this will give you a starting point!
To test in your browser, set get_cell to function get_cell(x) {return x;}, and then run parse_cell("=SUM(5,SUM(1,7,SUM(8,111)),7,8)"). It should result in 147 :)

I managed to do this using bacon.js. It accounts for cell interdependencies. As of now, it calculates values for javascript formula instead of excel formula by using an eval function. To make it work for excel formulae, all one has to do is replace eval with Handsontable's ruleJS library. I couldn't find a URI for that library... hence eval.

XML Javascript undefined error in ie9

I have a 'jargon buster' on my site that uses an xml file to load an A-Z of words which when clicked display a brief short explanation of each word. This works fine in all browsers bar the latest ie's which i get an 'undefined' error with. The jscript im using is below

In terms of how im calling the jscript im using <li>a</li>
which loads a list of all items that begin with f then when i click one of items from that list say "Fiduciary" it triggers javascript:Jargon.showDef('f1'); which in turns loads the and into a definition div
however in ie9 it displays "undefined" . It works in all other browers
Example of the XML below:
<letter id="f"> -<jargon id="f1"> <name>Fiduciary</name> <desc>in a position of trust. This includes people such as trustees looking after trust assets for the beneficiaries and company directors running a company for the shareholders' benefit.</desc> </jargon> -<jargon id="f2"> <name>Forfeiture</name> <desc>the loss of possession of a property because the tenancy conditions have not been met by the tenant.</desc> </jargon> -<jargon id="f3"> <name>Freehold</name> <desc>describing land that only the owner has any rights over.</desc> </jargon> -<jargon id="f4"> <name>Free of encumbrances</name> <desc>no one else having any rights over something. When property is owned by someone and nobody else has any rights over it, it is owned free of encumbrances.</desc> </jargon> </letter>

First, Firebug is your friend, get used to it. Second, if you paste each function and some supporting lines, one by one, you will eventually get to the following.
var DebugMode = (getQueryVariable("debug")=="1")
function getQueryVariable(variable)
You can't execute getQueryVariable before it is defined, you can create a handle to a future reference though, there is a difference.
There are several other potential issues in your code, but putting the var DebugMode line after the close of the getQueryVariable method should work fine.

It would help if you gave more context. For example, is
Failed to load source for:
http://localhost/js/m.js
the literal text of an error message? Where and when do you see it?
Also, does that code represent the contents of http://localhost/js/m.js? It seems that way, but it's hard to tell.
In any case, the JavaScript that you've shown has quite a few statements that are missing their semicolons. There may be other syntax errors as well. If you can't find them on your own, you might find tools such as jslint to be helpful.

make sure the type attribute in tag is "text/javascript" not "script/javascript".

I know it is more than a year since this question was asked, but I faced this today. I had a
<script type="text/javascript" src="/test/test-script.js"/>
and I was getting the 'Failed to load source for: http://localhost/test/test-script.js' error in Firebug. Even chrome was no loading this script. Then I modified the above line as
<script type="text/javascript" src="/test/test-script.js"></script>
and it started working both in Firefox and chrome. Documenting this here hoping that this will help someone. Btw, I dont know why the later works where as the previous one didn't.
