So I have a php which gets set of coordinates from the database , I want it to run through a jquery variable.
This is the PHP -
$sql = "SQL that works";
$vari = mysqli_query($con,$sql);
while($row = mysqli_fetch_array($loc))
{echo "[";
echo "''";
echo $row['cor1'];
echo ",";
echo $row['cor2'];
echo "]";
}
This is the jquery that I want it to pass through in this form -
var markers = [
['', 51.503454,-0.119562],
['', 51.499633,-0.124755]
];
Actually you have to change your php code like below:-
$sql = "SQL that works";
$vari = mysqli_query($con,$sql);
$data = array(); //create an rray variable
while($row = mysqli_fetch_assoc($loc)){ // use assoc for lighter $row array
$data[] = array('',$row['cor1'],$row['cor2']); // create sub-array and assign to final array
}
echo json_encode($data); //return final data to ajax
Note:-Now decode this json in your jQuery via parseJSON() and do further code.
If you don't want to use ajax, you can do something like this.
For the PHP,
...
$vari = mysqli_query($con,$sql);
$coOrds = mysqli_fetch_array($loc);
$coOrds = json_encode($coOrds);
?>
For the JS,
var coOrdsJson = <?php echo $coOrds; ?>;
var coOrds = $.parseJSON(coOrdsJson);
var markersArr = [];
for (var i=0; i < coOrds.length; i++ ) {
markersArr[] = "['', " + coOrds[i].cor1 + ", " + coOrds[i].cor2 + "]";
}
var markers = markersArr.join(',');
markers = "[" + markers + "]";
I've written the conditions down in JavaScript and if it's a down arrow then I want to update the database whereas currently it's not falling into the javascript condition and updating the database at server level. Any help will be appreciated.
Code:
<script language="javascript">
$(document).ready(function() {
totalgames=<?= $totalgames ?>;
//scoress = 0;
previous_s=0;
for(xx=totalgames; xx>=1; xx--){
score_ele = 'scores'+xx;
tdid_ele = 'tdid'+xx;
var tdd = document.getElementById(tdid_ele);
var scoress = document.getElementById(score_ele);
if(previous_s == 0){
tdd.innerHTML = "<img src='images/bullet.png'/>";
}else{
if(parseFloat(previous_s) > parseFloat(scoress.value)){
tdd.innerHTML = "<img src='images/arrow_up.png'/>";

The way you should execute you PHP-code using ajax is by moving the server side code to a separate file which you call apon in the ajax-request, the url.
One example is using jQuery.
$.ajax({
type: "POST",
url: "some.php",
data: { name: "John", location: "Boston" }
}).done(function( msg ) {
alert( "Data Saved: " + msg );
});
This documentation is located here
You send the information needed to execute the PHP-code in the data. These are then accessed by $_POST or $_GET depending on which type you chose.
If you're not intending to use jQuery, you can look here: Getting Started with AJAX - Updating Form via PHP.
Here are some good practices using ajax
I made a TicTacToe Game! Just for fun. It works and all, but can't tell once someone has won. I used .inArray to look for winning solutions on the current board. The idea is once a winning combination of squares is on the board, an alert will pop up ("You won Bruh"). Maybe the inArray is comparing the win arrays to the chosen elements opposed to the elements of the win arrays to the chosen elements? I'm stumped. Check out the jsfiddle if you're interested and leave a response if you've figured it out. Thanks. http://jsfiddle.net/QH6W9/7/
//UPDATE
I ended up using a magic square and checking if combinations of 3 added to 15 and implemented self teaching and basic AI using possible combinations and a MySQL db. I used a second script to let the computer play itself and build up the database. It's not the most perfect code but see for yourself..

At first glance, it looks like in
$(wins).each(function(){
var maybe = $.inArray(this,xs); //if Xs match combos win
...
}
you're checking if the array xs is found in the currently checked winning combination instead of just comparing this to xs (both 1-dimensional arrays). [Tried $.inArray(wins, xs) but it won't work.]
Could this be it?
UPDATE: this version works: http://jsfiddle.net/QH6W9/9/
I fixed your code to retrieve the ids of the X'ed fields with this:
var xs = $(".x").map(function(i, el) {
return parseInt($(el).attr('id'))
}).get(); // get ids as array
And also the detection of the win situation:
$(wins).each(function() {
var found = true;
for(var i =0; i<this.length; i++) {
found &= ($.inArray(this[i], xs) > -1);
}
if (!found) return;
alert("You Won Bruh");
var all = $(".square");
$(all).addclass('clicked'); //stops more turns
return;
});
You have a couple of issues.
First, you are putting all of the locations of .x into an array, and then seeing if that array is in the wins array.
Unfortunately, $.inArray() will only return an index if the items are the same item, not if they have matching values.
$.inArray([4,5,6], [[1,2,3], [4,5,6]]) // returns -1
var ary1 = [1,2,3];
var ary2 = [4,5,6];
$.inArray(ary2, [ary1, ary2]); // returns 1
$.inArray(ary2, [ary1, [4,5,6]]); // returns -1
Secondly, if you are at a state in the game where you have more than 3 X's, you will never match a winning position:
X O _
X X O
X O _
In this case xs will equal [1,4,5,7]. This is a winning position, but will not match any of your arrays.
There are a number of other ways to go about this. The easiest, given your wins array, is to iterate through each and check if the div at each location in the array is an X. If so, stop and declare a win.
Demo: http://jsfiddle.net/jtbowden/4BDwt/1/
Note, I cleaned up some other code in this example.
Removed the redundant clickable class, and use
.square:not(.clicked).
Replaced .click() with .on().
Removed the .square IDs and just use the div order in XOs as the location, using .eq() with the array position. IDs shouldn't start with numbers, and it is better to store data in a jQuery data attribute, like <div data-location="1">, and retrieve it with .data('location'). But, in this case, it wasn't needed as the div order tells us where it is.
Replaced $(array).each(function(){}) with $.each(array, function(){}). This is the correct way to iterate over a normal array that is not jQuery objects.
You had two problems in your program:
First, you had the following:
parseInt(number);
xs[i] = number;
xs[i] was still getting a string because parseInt() does not modify its parameter. Instead, it returns the numeric value. So I changed that code to the more compact:
xs[i] = parseInt(number);
Secondly, in your $(wins).each() loop, you were using $.inArray(), but you already have the individual array, so you really wanted to do an array subset comparison there. Since Javascript/jQuery has no built-in array subset function, I just compared each element in the array:
$(wins).each(function(){
console.log( 'template: ' + this );
var allIn = true;
for( var i=0; i<this.length; i++ ) {
console.log( this[i] );
if( $.inArray( this[i], xs ) == -1 ) allIn = false;
}
if ( allIn ){
alert("You Won Bruh");
And now it works. I only did it for X's, not for O's...I'll leave that up to you! You can see my jsfiddle solution here:
http://jsfiddle.net/HxGZE/2/
EDIT: my solution now works. See the jsfiddle for proof.
