JavaScript - Having Difficulty With Loops

I've recently picked up HTML and CSS, and am getting to grips really quickly. The principles are really straight forward, you just need to understand a few key principles and then with practice you can remember most tags/elements/attributes etc, although I would rather have the understanding rather then not have the understanding and remember all the tags (I can remember most tags I need anyway.

So PHP and Javascript are obviously the next ports of call once I feel I am proficient with HTML and CSS.

How hard is it to understand the principles of Javascript and become effective in it?

i have been tryin for a long time to get both of the javascripts(for the thumbnail to main img swap and the navigational arrow swap) to work in synch

http://***.com/nn.html

it needs to be so that after clicking on a thumbnail then on an arrow, the correct image in the correct order appears. as of now they are running separately and one has no influence on the other. forgive me if im not being clear. i keep trying to replace the id that one script is looking for with the same id from the other but this will not work..why?

please help me...believe me ive tried to help myself by reading all i can understand on the web about this but im in the dark

thanks

I'm an online web design student and i'm currently taking a javascript class
Ive used java in the past but that was ten years ago so ive been spending time refamiliarizing myself with it
I've ran into a problem with the popup coding I was given to use
I have to take this image gallery and make the image thumbnails pop up into the larger view of the image using just the java pop up window, but somehow for some reason my coding is opening up the image in both windows, the window that the thumbnails are on and the separate window, its frustrating me to death! i have to keep hitting the back button on the main page whenever i click on an image link because it opens it in both windows simultaenously. i have to submit the project because it's due but i want to work on getting this problem resolved for the future. I've attached a plain text notepad document to my post so you can see the coding

Hi,
I am using following code--
Code:

<td>
<centre>
<select id=\"extenddays\"  size=\"1\" name=\"extenddays\">
<option value\=\"2\"> 2 </option>
<option value\=\"4\"> 4 </option>
<option value\=\"7\"> 7 </option>
</select>
<a href=?ext_days=\"extendform.extenddays.value\" & ?extfid=" . $data->{'fid'} ." \" >
<INPUT TYPE=\"SUBMIT\" NAME=\"extend\" VALUE=\"extend\" />
</a>
</centre>
</td>

Here, I want that when I click on 'extend' button, it should redirect to the url given in the href.. But while forming url run time , it is not retrieving the value of "extenddays" ( which is selected option value)..

Please help.

Cheers,

Hi,

I am a JavaScript novice, and appreciate any help you can give.

For design reasons, we did not like the appearance of a still video on our web page. So I write a short little script to replace a picture that we selected, with the code for a flash player, once the image was clicked.

The code works exactly as designed on IE and Chrome. It works *almost* as designed on Firefox and Safari -- but on those browsers the "fullscreen" button in the plugin doesn't work.

It is *not* a problem with the FlowPlayer code. If I simply put the FlowPlayer code into a web page, it works fine. I think that somehow some browsers do not want to let the FlowPlayer expend outside of the JavaScript object box I created -- though that is just an hypthesis.

If you have any insight or suggestions, I would appreciate it.

The code:

Hey Guys! I've previously done HTML, but now started to learn some aspects of Javascript but getting rather confused with Loops! I've done a some coding for the Loop question (probably doesn't make sense) but I was wondering if you could help me out? I'm about as confused as a cow on a Astro Turf so my code may look terrible!

- For this question you will: Draw a flow chart and write a javascript function which will use a for loop and allow the user to enter the details for four students when the program is run and display the average. Assume that they equal weighting. Hint: Javascript may assume that the value received from a prompt is a string so use parseInt() to make sure the number is an integer.

Here is my code: (I'm using Aptana) Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"
   "http://www.w3.org/TR/html4/strict.dtd">
   <html>
   	<meta http-equiv="Content-Type" content="text/javascript; charset=utf-8"/>
   	<title>Average Marks</title>
   		 	<!-- Date: 2011-10-27 -->
                               <head>
   		 		<script type="text/javascript">
   		 			function marks () {
   		 				
   		 				var mark1 = 10;
   		 				var mark2 = 25;
   		 				var mark3 = 50;
   		 				
   		 			for(var mark1 = 10; mark1<20; mark1++)
   		 			   (var mark2 = 25; mark2<50; mark2++)
   		 			   (var mark3 = 50; mark3<90; mark3++)
   		 			{
   		 				alert(mark1 + "<br /> ");
   		 					 (mark2 + "<br /> ");
   		 					 (mark3 + "<br />" );
   		 				console.log(mark1)
   		 				console.log(mark2)
   		 				console.log(mark3)
   		 			}
						  
						}
						
						function average () {
						  
						  parseInt()
						}
   		 	</script>
   		 	<body onload="marks()">
   		 	</body>
   			</head>
   			</html>

P.S. I'm not using the prompt for the user to enter their details yet, as I wanted to test it with the marks already set.

Hello, i am new here however my knowledge is not that limited like that one guy wolf who oldMaster was helping with i read the RULES and his thread lol

so my question is, i have made a for loop and in side the for loop i wrote document.write(<td>date</td>"<td class = 'amt'>amount</td>);
where date, amount, firstName, and lastName, are the values of the date, amount, firstName, and lastName arrays for the index indicated by the current value of the for loop counter varible


so questions : i have spent the past 3 days looking online for the correct answer
document.write(<td>date</td>"<td class = 'amt'>amount</td>); ?

		<script type ="text/javascript">
		
	   function amountTotal(){
	   //i dont think we need an array made because we have called the external file called list.js which holds the arrays
	   
	   //sets the variable to 0
	   var total = 0; //new Array("firstName", "lastName", "street", "city", "state", "zip", "amount", "date");
	   
			//that loops through all the values in the amount array, at each point in the loop add the current value of the array item to the value of the total variable
		   for(var i = 0; i < amount.length; i++)
		   {	
				total = total + amount[i];
				
		   }//enf forloop
		   
		   //i must return the sum of all the values in the amount array
			
			return total;

Hello all.

I've spent a few days now browsing this forum along with guides on the net, I'm new to JS and I'm having a bit of trouble with loops. I just don't seem to get them, I was wondering if anyone had any tips or methods (the simpler the better ) for getting these learnt and done with?

Would appreciate any tips

Thanks

I am working on making 2 for loops of 2 arrays to get the total of them. Then I need to get the average heights. This is for a test, yet I have not got a clue, so I need clues as I cant get it to work and I am a new coder to javascript.

Code:

var heights = [15,16,17,18,19];
var numbers = [2,1,6,4,2];
var average = new Array(5);

average = 0

for (var heights = 0; heights <= 5; heights = heights+ 1)
{
total = 0
}
for (var numbers = 0; numbers <= 5; numbers = numbers + 1)
{
total = 0
average = heights / numbers;
}

document.write('The average height is ' + average);

Am I on the right road? I need to use this format and not functions. I have got 2 for statements but maybe I could do this with one, it is so tricky this javascript.

I created a For Loop and counter starts at 0, then increase in increments of 1
after each iteration of loop i run a command
1( add html code such as Code:

<td>named (part)</td>
<td class= 'num'>votes</td>

Then create variable of named percent use totalV for value of sum parameter

then i add html code of Code:

<td class='num'>(percent%(</td>

then i add a function named createBar(0 using race[0], name1, party1, and votes1 in parameter values

this is my coding
Code:

for (var i=0; i < name.length; i++)
{
document.write("<tr>");
document.write("<td>" name[i] + "(" + party[i] + ")</td>");
document.write("<td class='num'>" + votes[i] + "</td>");
 
var percent=calcPercent(votes[i], totalV)
 
document.write("<td class='num'>(" + percent +"%)</td>");
 
createBar(party[i],percent)
document.write("</tr>");
}
document.write("</table>");
}
</script>

</head>

so any improvements or what i am missing in my functions.

Hey Guys,

I'm currently a seasoned programmer who is in a programming class at my school. We're currently learning advanced JavaScript, and we're on the topic of nested loops.

After teaching us about for and while loops, my teacher gave us a little puzzle to solve. It's kind of difficult to explain, but I'll give you guys my current code and what it outputs.

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<title>Word Reversal</title>

<script type="text/javascript">

var ask = prompt("How many words do you want?","");

while (ask < "1")

{

	alert("You have to have at least one word!");

	var ask = prompt("How many words do you want?","");

}

var num = parseInt(ask) + 1;

var final = "";

for (var i=1; i < num; i++)

{

	var word = prompt("What's word " + i + "?");

	final = final + "Word " + i +": " + word + "<br/>";

}

</script>

</head>

<body>

<script type="text/javascript">

document.writeln(final);

</script>

</body>

</html>

The current output, when the user wants two words, and word 1 is one and word 2 is two, comes out to be:
Code:

Word 1: one
Word 2: two

Which is great, but the only problem is, this is what the output's supposed to be:
Code:

Word 2: two
Word 1: one

I'm stumped. I've had numerous programming challenges in my life which I've solved, but I'm not sure where to go next on this one. The script is supposed to use a nested loop, but what goes in what loop to reverse the order of the user's input?

I asked my teacher for help, but he told me "Ask someone else." I asked another seasoned programmer in my class, who was just about as stumped as I was, so I went back to my teacher. "Well, ask another person" he replied. And can you believe this guy has a Master's Degree of Computer Science? So I'm asking you guys: the community. I hope someone will be able to help me.

On top of that, I have to help and tutor two special education students in my class on this kind of stuff during class, and they can't get the project done until I get it done, as they learn from analyzing and copying my work (which my teacher told me to do). They get upset when they have nothing to code, and they end up goofing off the entire period, or using it as a study hall. I need to get them back on track, so we can move on to the next project.

Please help me with this code - it would be greatly appreciated.

Thank you!

I am doing practice problems for class (not homework), and I've gotten most of the coding down except for one stipulation. The exercise reads:

"Write a program that reads input of the number of hours an employee has worked and displays the employee's total and average (per day) number of hours.
The company doesn't pay overtime, so cap any day at 8 hours.

Sample Run:
How many days? 3
Hours? 6
Hours? 12
Hours? 5
Employee's total paid hours = 19
Employee’s average paid hours = 6.3333333"

I can't figure out how to include the bolded stipulation.
I've tried adding:
Code:

 if ( sum >8 ) {
            sum = 8; 
}

but I know that isn't right, and I can't think of any other solution. Can someone advise me on my work?


Code:

    public static void main(String[] args) {
        
    Scanner keyboard = new Scanner(System.in);
   System.out.println("How many days worked? ");
   int count = keyboard.nextInt();
   int i = 1;
   int sum = 0;
    
  while (i <= count) {
      System.out.println("Hours? ");
      sum += keyboard.nextInt();     
      i++;
       
    }
  
  System.out.println("Employee's total paid hours= " +sum);
  System.out.println("Employee's average paid hours= " +(double)sum/count);
  
  
  

}
}

Also! If anyone can explain to me why there has to be an initialization of " int sum = 0 ", that would be great. I just know I have to include it for this loop.

I've been asked to create a program which allows meteorologists to input a certain amount of data inputs of snowfall, and then the individual snowfall of each input itself.


In my mind this should prompt me for a data input as many times as their are inputs, however, it works only for the first data input, then it returns to blank page without prompts for the second input...

Any clues as to where I'm going wrong?

Hello codingforums.com!

Right, this is probably going but such a stupid newbie thread but here goes..

I've finally got myself into gear to start learning javascript. I've been watching video tutorials, learning from websites and simply learning by error.

I understand the concept of for loops, but the whole nested thing doesn't seem to click for some reason. I thought i understood and managed to write a piece of code that constantly writes '*' across the screen.

Could someone with some pretty damn good knowledge of javascript be able to walk me through step by step of my script to explain what actually is happening? It would help loads.

here is the script, many thanks!!

<script type="text/javascript">
var counter = 0;

function writeStars(){
for(i=0;i<1;i++){


for(a=0;a<=counter;a++){

document.write("*");

}
counter++
document.write("<br />");
}
}

setInterval("writeStars()", 200);
</script>
