Uncaught ReferenceError: $ is not defined when is defined

Background I'm making 4 calendars:

  • The Current Calendar
  • Next Month's Calendar
  • Last Month's Calendar
  • 2 Month's From now Calendar //$dateInt = date("U", strtotime("+2 months"));

I had the calendars building just fine, including the dynamic loading of values from my SQL Database Table (I'll just call it DB henceforth) . I have been doing PHP off and on since the late 90s but for whatever reason, I'd forgot the concept of class, so I switched my "functions.php" page where the calendar loads and added the class and __constructor instead.

The calendars still build just fine, but the dynamic loading and adding of the values from DB has stopped and is now throwing the Uncaught ReferenceError: $ is not defined at calendar.php:466:29 error. I did not move the JQuery portion of the code at all (other than it's inside a class now instead of a function...

The Code

<?php
$currentCal = new Calendar("Current");
$nextCal = new Calendar("Next");
$priorCal = new Calendar("Prior");
$wipCal = new Calendar("WIP"); //2 Month's from $currentCal

if (isset($_POST['cal'])) {
    new Calendar($_POST['cal']);
    unset($_POST);
}

class Calendar
{
    function __construct($cat)
    {
        include "assets/system/connect.php";
        try {
            //A LOT OF REDACTED SCRIPT FOR BUILDING THE CALENDAR BUT HERE'S THE FORMATTING FOR THE IDs ON THE FIELDS
            echo "  <tr class='content'>

                    $display = "<span class=location>$location</span><br/><span class=content>$department: $provider/$staff</span>";
                } else {
                    $display = "<span class=location>$location</span><br/><span class=content>$department: $provider</span>";
                }
                echo "<script>\$('#$tdID').html('$display');</script>"; //THIS IS WHERE THE ERROR IS FLAGGED
                //VALUE ON FIRST RUNTHROUGH IS:
                //$('#CentralCurrent11NonFlight').html('<span class=location>Big Timber</span><br/><span class=content>Cardio: Who/Staff</span>');</script>
        //REDACTING REMAINDER

I'm sorry the for the length - I tried to take out everything I didn't think was absolutely necessary. I can provide the full code if desired, just give me somewhere to send it to - it's over 100 lines.

I did check the Dev Console and Sources sections in Chrome and did find that CentralCurrent11NonFlight does exist:

<tr class='content'>
    <td class='nonFlight' id='CentralCurrent8NonFlight'></td>
    <td class='nonFlight' id='CentralCurrent9NonFlight'></td>
    <td class='nonFlight' id='CentralCurrent10NonFlight'></td>
    <td class='nonFlight' id='CentralCurrent11NonFlight'></td> //WINNER WINNER
    <td class='nonFlight' id='CentralCurrent12NonFlight'></td>
    <td class='nonFlight' id='CentralCurrent13NonFlight'></td>
    <td class='nonFlight' id='CentralCurrent14NonFlight'></td>
</tr>

Originally I thought the problem was that the first $ was being echo'd as a variable, so I added the \ character to remove that: echo "<script>\$('#$tdID').html('$display');</script>"; It didn't fix the problem, but I'm going to leave it as it seems more... appropriate... within the echo.

Any thoughts would be helpful.

Thank you!

ValueError: X has 10 features, but LinearRegression is expecting 1 features as input

So, I am trying to predict the model but its throwing error like it has 10 features but it expacts only 1. So I am confused can anyone help me with it? more importantly its not working for me when my friend runs it. It works perfectly fine dose anyone know the reason about it? cv = KFold(n_splits = 10) all_loss = [] for i in range(9): # 1st for loop over polynomial orders poly_order = i X_train = make_polynomial(x, poly_order) loss_at_order = [] # initiate a set to collect loss for CV for train_index, test_index in cv.split(X_train): print('TRAIN:', train_index, 'TEST:', test_index) X_train_cv, X_test_cv = X_train[train_index], X_test[test_index] t_train_cv, t_test_cv = t[train_index], t[test_index] reg.fit(X_train_cv, t_train_cv) loss_at_order.append(np.mean((t_test_cv - reg.predict(X_test_cv))**2)) # collect loss at fold all_loss.append(np.mean(loss_at_order)) # collect loss at order plt.plot(np.log(al...

Sorting large arrays of big numeric stings

I was solving bigSorting() problem from hackerrank: Consider an array of numeric strings where each string is a positive number with anywhere from to digits. Sort the array's elements in non-decreasing, or ascending order of their integer values and return the sorted array. I know it works as follows: def bigSorting(unsorted): return sorted(unsorted, key=int) But I didnt guess this approach earlier. Initially I tried below: def bigSorting(unsorted): int_unsorted = [int(i) for i in unsorted] int_sorted = sorted(int_unsorted) return [str(i) for i in int_sorted] However, for some of the test cases, it was showing time limit exceeded. Why is it so? PS: I dont know exactly what those test cases were as hacker rank does not reveal all test cases. source https://stackoverflow.com/questions/73007397/sorting-large-arrays-of-big-numeric-stings
