Rather than re-inventing the wheel, have you considered using one of the many existing libraries that provide this type of functionality?

<java>
I am trying to store user input (string values) into a 2d array but am unable to figure out how to do a for loop for String values.
User will input a First Name, Last Name, Phone, and Age
public class Lab2
{
public static void main(String[] args) {
//Example Data but need it entered by a user
String [][] array = {
{"Ryan", "Smith", "555555555", "12"},
{"George", "Young", "123456789", "52"},
{"Frank", "McDonnell", "555123789", "18"}
};
//Create a for loop for user input
//Displays the entire array
for (int row=0; row<array.length; row++){
="" for="" (int="" col="0;" <array[row].length;="" col++){
="" system.out.print(array[row][col]+"="" ");
="" }
="" system.out.println();
}
}
}

You could possibly fetch the RSS feeds from different news websites, like BBC etc. They all provide you with functionality to fetch the latest feeds from their servers and you can then render those RSS feeds on your website.
The website would then act as an RSS feed reader. Before you begin, I would recommend that you read about RSS[^], RSS feeds (same as RSS) and RSS Readers (the application which pulls the RSS feeds and then display them in the device). Understand them and them implement the service in your application.
Also, why would you like to pull it using JavaScript when you can pull it using your server-side language too? Which would be much more fast and efficient.

I want to load a png image in base64 to html5 canvas element. I have this code:
<html>
<head></head>
<body>
<canvas id="pageCanvas"></canvas>
<script type="text/javascript">
var canvas = document.getElementById("pageCanvas");
var ctx = canvas.getContext("2d");
var imageData ="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAIAAAACDbGyAAAAAXNSR0IArs4c6QAAAAlwSFlzAAALEwAACxMBAJqcGAAAAAd0SU1FB9oMCRUiMrIBQVkAAAAZdEVYdENvbW1lbnQAQ3JlYXRlZCB3aXRoIEdJTVBXgQ4XAAAADElEQVQI12NgoC4AAABQAAEiE+h1AAAAAElFTkSuQmCC";
var imageObj = new Image();
imageObj.src = imageData;
ctx.drawImage(imageObj, 50, 100);
</script>
</body>
</html>
The above code working well in IE, chrome, Microsoft edge. But in Firefox the image was not displayed. It display blank page. Sometime when we reload the page then it displayed an image in canvas.
Best,

There is no such code that works "sometimes". Code either works or doesn't work, but it can depend on the underlying libraries and stuff like that so the first time it doesn't work because the framework isn't ready and then works because everything is set up.
But it is still not convincing to believe that a reload fixes everything. Take this, press F12 and try to look for the error that this image gives. Console would log the error and you can see that error to find a solution, or post it here so we may help you.

I'm doing an assignment with an order form and was wondering if there is a function that will auto fill the cost field after entering the quantity field?
|
|
|
|

You really miss the point of having an assignment: you are supposed to figure it out, and in the process, learn!
You may wish to get used to that idea sooner, rather than later, as that's what this business is all about.
Here's something for you to consider that's an important part of figuring out how to answer your question: where is the cost-per-unit data located at the time the quantity is entered? A lot depends upon that.

Yeah - I noticed that when I tried to see what else he's been up to (i.e., aside from trying to get his homework done). I think what was most annoying is that I even gave him some suggestions rather than the tried-and-true "Do Your Own Homework".
Maybe someone can develop a CP-AI that would recognize the new accounts created by those who are thrown out of the hamster cage.

Lots of homework[^] it seems.

No. You have to write it yourself.

I still can believe the web runs on it! If there is any proof the devil exists javascript must be it.
It is so easy to make a mistake and not catch it until you are debugging.

I can understand your frustration. Maybe you want to take a look on TypeScript.
|
|
|
|
|
I've done some typescript and I absolutely love what Anders Hedjelsberg did.
The library I will be using still needs a typescript facade though , so I have to stick with javascript.
I can't help but wonder what were the twisted minds that created this devil-spawn language thinking when they were going through the design process.

I do believe they were thinking about making a language the ENTIRE web could run on. Not simply making the process easy or simple for you.

Auto-completion can't do it all.
In a compiled language, the compiler might catch an error - but not a bug.
In a scripted language, you need to run it.
If either of these routes is unsuitable, I would suggest finding an alternate language for your problems.

Well , of course not , but it's a great tool when you are learning a new library. Even after you have learned it's a big help.
In a compiled language, the compiler might catch an error - but not a bug.
In a compiled language the compiler will catch all syntax errors.
And it will spot some bugs ( dead code, unused variables , uninitialized variables).
If either of these routes is unsuitable, I would suggest finding an alternate language for your problems.
Of course they don't suite my needs, I'll be using typescript whenever I can unluckily for some cases there is no other choice than using javascript.

That's true for any language. But JavaScript does keep you on your toes. If you miss a closing bracket somewhere you may not notice it for quite a while. JS can be a pain.

I want to use buttons in tree. So I used the article Working on JSON objects in jQuery and MVC given by Dr. Song Li in 24 Nov 2010. I have taken button instead of textnode. The buttons work fine first time. But these buttons do not fire after addExamBySession or addExamByjson is clicked.

var dt = new Date(parseInt(dateStr.substr(6)));
return prependZero((dt.getMonth() + 1))
+ "/" + prependZero(dt.getDate())

+ " " + prependZero(dt.getHours())
+ ":" + prependZero(dt.getMinutes())
+ ":" + prependZero(dt.getSeconds());

var FixDateinJson = function (JsonStudents) {
$.each(JsonStudents, function (i, JsonStudent) {
$.each(JsonStudent.ClassesTaken, function (i, JsonClass) {

JsonExam.ExamTime = dateDeserialize(JsonExam.ExamTime);
