Javascript condition not working as expected

I have a JS code which works fine when
checkQueryString != "M"
but When the value becomes checkQueryString == "M" it doesn't goes inside the loop
Here is my code.
function GridExpInfo_ClientAdd(record) {
var checkQueryString = '<%= Request.QueryString["Mode"] %>';
if (checkQueryString != "M") {
if ($('input:checked').length > 0) {
document.getElementById("GridExpInfo_tplRowEdit3_ctl00_txtExpRefNo").disabled = true;
document.getElementById("GridExpInfo_tplRowEdit3_ctl00_txtExpRefDt").disabled = true;
document.getElementById('GridExpInfo_tplRowEdit3_ctl00_ddlStageType').value = "";
var last_value = 0;
var last_text;
var checkboxlist = document.getElementById('ddlStatus');
var checkOptions = checkboxlist.getElementsByTagName('input');
var listSelected = checkboxlist.getElementsByTagName('label');
for (i = 0; i < checkOptions.length; i++) {
if (checkOptions[i].checked == true) {
last_text = listSelected[i].innerText;
last_value = checkOptions[i].value;
document.getElementById('GridExpInfo_tplRowEdit3_ctl00_ddlStageType').innerHTML = "";
var ObjPriOptionExp = document.createElement("OPTION");
ObjPriOptionExp.text = last_text;
ObjPriOptionExp.value = last_value;
document.getElementById('GridExpInfo_tplRowEdit3_ctl00_ddlStageType').add(ObjPriOptionExp);
}
}
}
if(checkQueryString == "M")
{
alert('Value is M now');
}
else {
alert('Kindly select the stage');
}
}
}
So my question is, why it doesn't goes inside if when it matches to M

Because
if (checkQueryString == "M") {
alert('Value is M now');
} else {
alert('Kindly select the stage');
}
Has inside if (checkQueryString == "M")
So try this
function GridExpInfo_ClientAdd(record) {
var checkQueryString = '<%= Request.QueryString["Mode"] %>';
if (checkQueryString != "M") {
if ($('input:checked').length > 0) {
document.getElementById("GridExpInfo_tplRowEdit3_ctl00_txtExpRefNo").disabled = true;
document.getElementById("GridExpInfo_tplRowEdit3_ctl00_txtExpRefDt").disabled = true;
document.getElementById('GridExpInfo_tplRowEdit3_ctl00_ddlStageType').value = "";
var last_value = 0;
var last_text;
var checkboxlist = document.getElementById('ddlStatus');
var checkOptions = checkboxlist.getElementsByTagName('input');
var listSelected = checkboxlist.getElementsByTagName('label');
for (i = 0; i < checkOptions.length; i++) {
if (checkOptions[i].checked == true) {
last_text = listSelected[i].innerText;
last_value = checkOptions[i].value;
document.getElementById('GridExpInfo_tplRowEdit3_ctl00_ddlStageType').innerHTML = "";
var ObjPriOptionExp = document.createElement("OPTION");
ObjPriOptionExp.text = last_text;
ObjPriOptionExp.value = last_value;
document.getElementById('GridExpInfo_tplRowEdit3_ctl00_ddlStageType').add(ObjPriOptionExp);
}
}
}
} else if (checkQueryString == "M") {
alert('Value is M now');
} else {
alert('Kindly select the stage');
}
}

Javascript in_array

In php this is a nice way of asking is a value is one of a few options
if( in_array($needle, [1,325,'something else']) ){
//do your thing
}
But in the world of javascript is there an equiv. that doesn't require writing a bespoke function such as:
function inArray(needle, haystack) {
var length = haystack.length;
for(var i = 0; i < length; i++) {
if(typeof haystack[i] == 'object') {
if(arrayCompare(haystack[i], needle)) return true;
} else {
if(haystack[i] == needle) return true;
}
}
return false;
}
function arrayCompare(a1, a2) {
if (a1.length != a2.length) return false;
var length = a2.length;
for (var i = 0; i < length; i++) {
if (a1[i] !== a2[i]) return false;
}
return true;
}
Use case of the above js bespoke function
if( inArray( somvar, [1,2,'something else']) ){
do the javascript thing
}
FROM THE COMMENTS
this is the most accurate answer: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/includes

var needle = 325;
if( [1,325,'something else'].indexOf(needle) !== -1 ){
//do your thing
};

You can use Array.prototype.find():
var data = ['Lorem', 'Ipsum', 'Sit']
var foundSit = data.find(function(item){
return item == 'Sit';
});

Using the input box instead of pop function

How can I use an input box instead of prompt on this code?
Code is
here.
Once I click on the link; a prompt pops up and asks to type a number or Q to quit. How would I change that to input box?
function Stack() {
var items = [];
this.push = function(element){
items.push(element);
};
this.pop = function(){
return items.pop();
};
this.peek = function(){
return items[items.length-1];
};
this.isEmpty = function(){
return items.length == 0;
};
this.size = function(){
return items.length;
};
this.clear = function(){
items = [];
};
this.print = function(){
alert("Stack Elements are:"+items.toString());
};
}
Declare stack object:
var stack = new Stack();
while(1)
{
var element = prompt("Enter stack element,(q or Q to exit)", "");
if(element == 'q' || element =='Q')
{
break;
}
else
{
if(element=='*'
|| element=='+' || element=='-' || element=='/')
{
//Check if stack is empty
if(stack.isEmpty() || stack.size<2 )
{
alert("Invalid Operation, Stack is empty or size is less than 2");
}
else
{
var op1 = stack.pop();
var op2 = stack.pop();
if(element=='*')
{
var res = op1 * op2;
}
else if(element=='+')
{
var res = op1 + op2;
}
else if(element=='-')
{
var res = op1 - op2;
}
else if(element=='/')
{
var res = op1 / op2;
}
stack.push(res);
stack.print();
}
}
else
{
stack.push(element);
stack.print();
}
}
}

try following example :
FIDDLE
var stack = new Stack();
function Stack() {
var items = [];
this.push = function(element) {
items.push(element);
};
this.pop = function() {
return items.pop();
};
this.peek = function() {
return items[items.length - 1];
};
this.isEmpty = function() {
return items.length == 0;
};
this.size = function() {
return items.length;
};
this.clear = function() {
items = [];
};
this.print = function() {
theList.options.length = 0;
for (var i = 0; i < items.length; i++) {
var theOption = new Option(items[i]);
theList.options[theList.options.length] = theOption;
}
};
}
function pushStack(newVal) {
if (newVal == '*' || newVal == '+' || newVal == '-' || newVal == '/') {
//Check if stack is empty
if (stack.isEmpty() || stack.size < 2) {
alert("Invalid Operation, Stack is empty or size is less than 2");
} else {
var op1 = stack.pop();
var op2 = stack.pop();
if (newVal == '*') {
var res = op1 * op2;
} else if (newVal == '+') {
var res = op1 + op2;
} else if (newVal == '-') {
var res = op1 - op2;
} else if (newVal == '/') {
var res = op1 / op2;
}
stack.push(res);
}
} else {
stack.push(newVal);
}
}
function popStack() {
var popVal = stack.pop();
if (popVal == undefined)
return "Empty stack!";
else
return popVal;
}
function showStack() {
stack.print();
}
<FORM>

Tic Tac Toe with Minimax and Javascript

I am attempting to create a Tic Tac Toe game using Javascript as part of my learning on FreeCodeCamp and after my 5th attempt still haven't managed to get it to work. I think i'm doing the correct thing, but the computer AI is still making very stupid decisions and loosing.
Here is my entire AI function, which can be called using a console log to see the recommended move from the AI. However when i hard code values for moves already taken and ask for the next move, it doesn't pick what i would expect.

I've checked the scoring function and from what i can see it is returning the expected score for any move i try, but because of the shear number of possibilities calculated it's very hard to debug efficiently.
Any help/pointers on this would be most appreciated as i have really hit a brick wall with this, can't see the forrest for the trees e.t.c
If you would like to test this with the GUI, it's on codepen at - http://codepen.io/gazzer82/pen/yYZmvJ?editors=001

So after banging my head against this for day, as soon as i posted this i found the issues. Firstly using the wrong variable for minormax in my reduce function, so it wasn't flipping correctly and not setting the winOrLoose value correctly for a score of -100. Here is the corrected version.
