From Wicked musical, Glinda sings to Elphaba (For Good):
I've heard it said
That people come into our lives for a reason
Bringing something we must learn
And we are led
To those who help us most to grow
If we let them
And we help them in return
Well, I don't know if I believe that's true
But I know I'm who I am today
Because I knew you...
Like a comet pulled from orbit
As it passes a sun
Like a stream that meets a boulder
Halfway through the wood
Who can say if I've been changed for the better?
But because I knew you
I have been changed for good
I've heard it said
That people come into our lives for a reason
Bringing something we must learn
And we are led
To those who help us most to grow
If we let them
And we help them in return
Well, I don't know if I believe that's true
But I know I'm who I am today
Because I knew you...
Like a comet pulled from orbit
As it passes a sun
Like a stream that meets a boulder
Halfway through the wood
Who can say if I've been changed for the better?
But because I knew you
I have been changed for good
Local Storage Methods #2

Local Storage Management Methods #1
zhlédnutí 103Před 4 lety
We look at the useful methods and behaviours to manage local storage: setItem(), getItem(), removeItem(), clear() and key(). We also look at how we can loop around them in two ways (using for x in localStorage and key()). We look at the script and the actions in the development area obtained by F12 in Chrome. The script can be found at jsls ciphers.repl.co/
Local Storage JS Management #3
zhlédnutí 61Před 4 lety
Uses W3Schools' script to explain that local storage on the client-side has creation, editing, display and deletion facilities managing items that are a key-value associative array like a map. The key is unique but maybe named (as in this simple case) and the values are strings. Editing is done in the development system (F12 in Chrome). We look at localStorage() methods.
Curious Quadratic

A quadratic solutions seen in the film Hidden Figures (2016). Can you solve the one a 7-year old girl does back in the 1930's? Note: factorising a quadratic equation depends on the fact that the form is fixed. It requires only a little arithmetic and understanding negative numbers. The rules used provide shortcuts and doubtless young Kathy did that as mental arithmetic confirmed on the board bu...

We look at a product-order-customer entity relationship diagram and discuss its entity integrity, move to a brief schema showing referential integrity on orders table and implement with a script to show domain integrity. The examples are run in Oracle Database Express. Of course integrity is really important when using insert, update and delete SQL keywords. The tutorial notes are found in a PD...

I script is analysed step by step, each statement run in the SQl command facility. A simple pair of tables with a 1:M relationship is implemented (customers-orders) and primary and foreign key constraints added to enforce referential integrity. Some records are added to each table to show the power of the inner join primary to foreign key.

I love your video!!! Straight forward and easy to understand. Thanks
Im in a rush studying for a handson exam tomorrow and your vid is a life saviourrr. Thank you very muchhhhhh
Thank you!
Yo just wanna say that GOD loved the world so much he sent his only begotten son Jesus to die a brutal death for us so that we can have eternal life and we can all accept this amazing gift this by simply believing in him (Jesus) asking for the forgiveness of your sins and forming a relationship with heavenly father.

Awesome this was so much help.
This can be done via the NetBeans GUI itself. At the beginning of the video, on the top right, there's the Palette window and in it, the 2nd in the right column is the Button Group. After adding the Radio Buttons, drag a Button Group on to the canvas. It won't physically show anything and that's ok. Then go to the Properties of each of the Radio Buttons, and under "buttonGroup" select "buttonGroup1", assuming you didn't change the name of the Button Group.
Good observation. It will mask the mutual exclusivity property I was illustrating though. Other languages like JavaScript and forms in HTML have this necessary step but no GUI helper.
Thank YOu man
Doc
Very informative thanks.
Thankyou!
Sir using react js how to collect form fields and show them on the same page?
I do not think you would want to do so because the trick we do here is because we do not have a server-side script to handle the posted data. React boasts tools to do just that. We are looking at HTML and JavaScript forms.
Thank you soooooooo much! 😄
Thank you
Thanks for this! Straight forward and simple.
hi. does this still work on the time? cuz I use jspinner to record time but I don't know how to get the value/
You choose date instead of number, I would guess, Freyja. See www.roseindia.net/java/example/java/swing/ShowTimeJSpinner.shtml
@@GrahamRobertsGCR oh wow! Thanks for the reply! I'll look through the website. Tysm!
No bells, no whistles, just upfront good teaching. Thank you Sir ☺️
What I needed.
Sir, can you please explain how to display these entered datas in the next page ?
Take away the return false phrase in the submit button onclick handler and the data is thrown away! The page looks as if nothing happened. But the data was posted. Add this instead of the form header: <form name='myform' method='GET' action=''> When you run that app page you see something like this in the browser path bar: file:///C:/Users/graha/OneDrive/Desktop/jscode.html?name=Graham&favourite=Red&mycheckbox=on So, the data is sent but when not shown on the same page is thrown away because you do not capture it using the JavaScript check() function. This tutorial was about tricking form interaction to the same page. If it is captured on a different page you need what is called a server-side programming language like PHP. And that is a whole area known as server-side programming. It is essential to the database approach and modern so-called AI systems like Amazon's Echo Dot, although it hides that under a cloak of voice searching and population of the form.
@@GrahamRobertsGCR Okay, Thank you Sir😊👍
Please someone say how to display the values of selected checkboxes
The trick here is to know that the checkbox has a value that is true or false and to trap that and write a message that intelligently interprets that value. Also, note that you may benefit from exploiting the onclick event handler instead of a form submission, and using style (I avoided that complication) - see www.w3schools.com/howto/howto_js_display_checkbox_text.asp But that is not what you asked for! Here is my extended script fyi <script> function check() { //document.writeln('Hi '+document.myform.name.value); document.getElementById('f1').innerHTML = document.myform.name.value; document.getElementById('f2').innerHTML = document.myform.favourite.value; if (document.myform.mycheckbox.checked) { document.getElementById('f3').innerHTML = "I have deficient colour vision"; } else { document.getElementById('f3').innerHTML = ""; } } </script> <form name='myform'> <p>What is your name, please? <input type = 'text' name='name' value = 'Graham'> <p>What is your favourite colour, please? <select name="favourite"> <option value=Red>Red</option> <option value=Green>Green</option> <option value=Blue>Blue</option> <option value=Yellow>Yellow</option> <option value=Black>Black</option> <option value=White>White</option> </select> </p> I have deficient colour vision: <input type="checkbox" name="mycheckbox"> <p><input type = 'submit' onclick='check(); return false'></p> <!-- note that return false after the function call is vital to stop page refresh --> </p> </form> <p>Submit the form and I will show your name and your favourite colour below:</p> <p id='f1'>meaningless text to denote the holding id we call f1</p> <p id='f2'>meaningless text to denote the holding id we call f2</p> <p id='f3'>meaningless text to denote the holding id we call f3</p>
@@GrahamRobertsGCR Okay, Thank you Sir for explaining the program. God bless you.😀😊
This is creepy. Just knowing how everything is math and numbers and how numbers are the ultimate truth. Mathematics are already there. The values we add, the formulas we figure out, is just our discovery of this truth.

Thank you soo much sir.. It's really helpful to me
Many thanks Mr. Graham. am a beginner, and i have problems in algorithm, flowchart and pseudocode. i love this presentation. there wasn't any jargon to confuse beginners, simple English was used. You also took your time in the explanation, the ascent was clear to understand. but the lessons was too short. i have passion in coding but am thinking quitting because i don't understand the basis. please do you a have full video to help people like me or any website to learn more from you ? please help me. any contact to for private conversation?
