codemonkey

codemonkey is fun and teaches basic programming in a way that is accessible to kids

APS fail

I can not watch the video for bitsbox due to connection issues that I believe are the result of APS blocking YouTube.

codecombat

I'm not sure how well codecombat teaches programming concepts. However it is extremely addicting. It may get some students interested in programming. However I find it lacking and if I knew nothing of programming I would just find this annoying

finally

finally finished my project for Khanacademy, now moving on to animation

apearently it will not overwrite a session once it is saved the first time

grrrr

saved and improved

I got it back to where it was and gave it a red beak

grrr

my stupid project didn't save, so I have to start over

my plan

I plan to finish the current and following units in Khan academy this week

my first spin off in Khan academy

Khan academy

I will explore the Khan academy JS course and compare it to codeacademy

so I really like Khan academy, you are actually taught by other people and there is much more collaboration also you get to have more variety in what you can do

5/5

I am going to work on codeacademy Javascript lesson Arrays and Objects in JS

5/1

finally found a way to incorporate && and || into my Javascript Choose Your Own Adventure 2. While Codeacademy said it worked, there is at least one logical error in my code. I put the code on the server and the problem still exists. Here is the source code.

alert("You are on a quest to seak the Holy Grail.");
alert("You approch a bridge.");
alert("Suddenly ...");
alert("Stop!  Who would cross the Bridge of Death must answer me these questions three!  Ere the other side he see.");
var user = prompt("What is your name?");
user.toUpperCase();
switch(user)
{
    case 'SIR LANCELOT' :
        var quest = prompt("What is your quest?");
        quest.toUpperCase();
        var color = prompt("What is your favorite color");
        color.toUpperCase();
        if (quest === "TO SEAK THE HOLY GRAIL" || color === "BLUE") {
            alert("You cross the bridge.");    
        }
        else {
            alert("You are cast into the Gorge of Eternal Peril.");
        }
        break;
    case 'SIR GALAHAD' :
         var quest = prompt("What is your quest?");
        quest.toUpperCase();
        var color = prompt("What is your favorite color");
        color.toUpperCase();
        if (quest === "I SEAK THE GRAIL!" && color === "GREEN") {
            alert("You cross the bridge");
        }
        else {
            alert("You are cast into the Gorge of Eternal Peril.");
        }
        break;
    case 'SIR ROBIN' :
        var quest = prompt("What is your quest?");
        quest.toUpperCase();
        var Assyria = prompt("What is the capital of Assyria?");
        Assyria.toUpperCase();
        if (quest === "TO SEAK THE HOLY GRAIL" && Assyria === "NINEVEH") {
            alert("You cross the bridge.");
        }
        else {
            alert("You are cast into the Gorge of Eternal Peril.");
        }
        break;
    case 'ARTHUR KING OF THE BRITAINS' :
        var quest = prompt("What is your quest?");
        quest.toUpperCase();
        var swallow = prompt("What is the average air speed of an unleaden swallow?");
        swallow.toUpperCase();
        if (quest === "TO SEAK THE HOLY GRAIL" && swallow === "AFRICAN OR EUROPEAN")  
        {
            alert("The Bridgekeeper is cast into the Gorge of Eternal Peril and you cross the bridge");
        }
        else 
        {
            alert("You are cast into the Gorge of Eternal Peril.");
        }
        break;
    default :
        var quest = prompt("What is your quest?");
        quest.toUpperCase();
        var color = prompt("What is your favorite color");
        color.toUpperCase();
        if (quest === "TO SEAK THE HOLY GRAIL" || color === "GREY") {
            alert("You cross the bridge.");    
        }
        else {
            alert("You are cast into the Gorge of Eternal Peril.");
        }
        break;
};

4/29

finally fixed the problem in jQuery, although still no idea why it gave me the results it did

4/22

adding elements

.append

makes the added element a last child

.prepend

makes the added element a first child

.appendTo

does the same as .append except that the added element is in front of the method

.prependTo

does the same as .prepend except that the added element is in front of the method

4/21

object = $(' ') and is followed by a .event

objects inside jQuery events must be inside a function

4/13

more than one selector can go inside of the $(' ')

this refers to whatever is above it

Chose your own adventure game, stuck

I started with a question simply asking "What is your name?" but now I can't see a place for && and ||.

OK this is getting really annoying! Chrome keeps giving me the "He's dead Jim" blue screen of death every time I visit Codacademy's jQuery course

jQuery variables

jQuery variables are done just like JavaScript variables except the are conventionally preceded by a "$" to show that the contain a jQuery object.

intro to jQuery.

jQuery is mostly like JavaScript except that it actually manipulates a website's source code. The overall syntax is the same except that jQuery has a unique syntax for its objects. It appears to be organized like HTML and CSS in the sense that it is like a tree, with object function sets within object function sets.

logical operators

&&

and - true only if all are true, false if only one is false:

true && true // = true
true && false // = false
false && true // = false
false && false // = false

||

or - true if only one is true, false only if all are false:

true || true // = true
true || false // = true
false || true // = true
false || false // = false

!

not so !true = false and !false = true

switch

• switch appears to be a form of if else statement except it is a loop of sorts
• case is like if/else if of the loop, it checks to see if the condition is equal to the variable and then moves to the next case, unless their is a break
• default is always run unless the program breaks, functions like the else

var answer = prompt("What do you do in your free time?"); switch(answer) { case 'play games': console.log("you like me and probably have no life"); break; // Add your code here! case 'program': console.log("you are like me and have no life, but you at least have a skill for a job"); break; case 'skate': console.log("seems like you get around"); break; case 'hang out with friends': console.log("you are lucky to have so many"); break; default: console.log("well that's interesting"); }

set up index and minimal page in jQuery today

dragon slayer

var slaying=true; var youHit=Math.floor(Math.random()*2); var damageThisRound=Math.floor(Math.random()*5 + 1); var totalDamage=totalDamage+damageThisRound; while(slaying) { if (youHit===1) { console.log("you hit the dragon"); if (totalDamage>=4) { console.log("you slew the dragon!"); slaying=false; } else { youhit=Math.floor(Math.random()*2); } } else { console.log("the dragon burnates you, you are dead"); } slaying=false; } play this game on my site

while loops

While loops continue to run as long as there condition is true

do is used to run something at least once and then as long as the following while loop is true

for loops and arrays

I finally found out the problem with my js. One must be sure to have the correct String being pushed

var text=":LJSDFkl as;jdfk Jonathan LKSJFDkjasfjioodsj kdjfoa[jsdif oajdfioasdjfjkads ioah fidha oiioreah iodsajfoi;dhadoi g Jonathan ] alksjdfkasjdfiojadsiojfioajsdifojsdaiojfioajsdofijaoispjf Jonathan"; var myName = "Jonathan"; var hits = []; for (var i = 0; i < text.length; i++) { if (text[i] === myName[0]) { for (j = i; j <= i + myName.length; j++) { hits.push(text[j]); } } } console.log(hits);

Arrays

arrays are sets of data, both strings and numbers can be in an array at the same time, arrays are stored in variables

var myarray[4, "annoying", "food" 5]
