JavaScript - Loops In Javascript
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 Similar TutorialsThis is a final loops in an exercise here is my code Code: <script type="text/javascript">
var counter;
for (counter=0; counter<amount.length; counter++) {}
{
document.writeIn(counter+"<br/>");
document.writeIn("<tr><td>"date"[counter]"</td>");
document.writeIn("<td class = 'amt'>myArray</td>");
document.writeIn("<td>"firstName[counter]"</td>");
document.writeIn("<td>"lastName[counter]"</td>");
document.writeIn("<td>"street[counter]"<br />");
document.writeIn("<td>"+street[counter]+" "+city[counter]+" "state[counter]+" "+zip[counter]+"</td></tr>);
Total=total+amount[counter];
document.writeIn("<table>");
}
</script>
This is what i have, what do i need to do to make this more proper and written properly? thanks Hi, Which among the following for iterating objects in JavaScript is better in terms of performance & usage? A) property enumeration: for (var propName in someObject) { var value = someObject[propName]; } B) Array protocol for (var i=0; i<someObject.length; i++) { var value = someObject[i]; } C) forEach method Can forEach method be used across various browsers and OS? K Hi guys, I am new to learning javascript and have a test tomorrow on for loops. I know the answers to the three following loops but i wondered if anyone could take the time to explain to me how to find the answer from the code as I have no idea on how to find the answers (the answer is what is displayed in the alert). Many thanks, Mike The loops are these three: 1. var a=4;b=6; for(var c=0;c<=a;c++){b=b+c;} alert(b); (answer is 16) 2. var v=1; for(i=1;i<5;i++) for(j=2;j<5;j++) v+=1; alert(v); (answer is 13) 3. var s=0; for(i=0;i<=8;i++) if((i%2)==0)s+=1; alert(s); (answer is 5) We have created this function with loops and arrays Problem is the loops work only when I take out the function when the function is in place, nothing works, it is part of exercise anyone have suggestions here is my code Code: title>Congressional Races</title>
<link href="results.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="votes.js"></script>
<script type="text/javascript">
function totalVotes(votes){
var total=0;
for (var i = 0; i <votes1.length; i++) {
total = total + votes1[i];
}
document.write(total);
}
</script>
}

thanks all who can help This is driving me crazy. I simply want to display the values of the checkboxes with a specific name. This loop executes only once, then stops, showing no error msg. I have found no similar problem elsewhere on the net and have done a ton of tests, but cannot find out why it won't continue to loop. I've included the whole html file. Please Help! Code: <HTML>
<SCRIPT language="JavaScript">
function test1()
{
var chkLen=document.frmTable.CHK0.length;
for (k=0;k<chkLen;k++)
{
//execution stops after one loop. no error msg.
document.write(document.getElementsByName('CHK0')[k].value);
}
}
</SCRIPT>
<FORM NAME=frmTable>
<TABLE BORDER=1>
<TR>
<TD><INPUT TYPE=CHECKBOX NAME=CHK0 VALUE='one'>1</TD>
<TD><INPUT TYPE=CHECKBOX NAME=CHK0 VALUE='two'>2</TD>
<TD><INPUT TYPE=CHECKBOX NAME=CHK0 VALUE='three'>3</TD>
</TR>
</TABLE><BR>
<INPUT TYPE=BUTTON VALUE='Go' onClick=test1()>

I want to learn javascript and I found codecademy.com which seems like a great way to learn the language. Before the first lesson it says Quote: You should be comfortable with loops, if statements, functions, and objects before attempting this course. Can someone explain what these are or point me in the direction where I can find the answers? I tried searching with google, but I havent found anything that clearly states what exactly the loop, object, etc. is. 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>); ?

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. Regards I have the following nested for loops: Code: for (i;i<tag('entry').length;i++) {
content = content + '<tr>';
for (x;x<tag('header').length;x++) {
content = content + '<td style="width:' + tdWidth + '%; border:solid 1px #000;">' + tag('item')[x].firstChild.nodeValue; + '</td>';
}
x+=tag('header').length;
content = content + '</tr>';
}
For some reason, it seems to only loop the outer for loop once. BTW, tag() is defined, I just didn't include it. Help is appreciated. Thanks, Julian 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> Hi everyone. I have a loop question. This is my assignment for my Comp Apps class. The whole thing is a store selling guitar picks. What I'm missing now is a loop. After the costumer places the order, he has the choice to go back and buy more or complete the order. In the end all the order the costumer placed adds up to the total. This is what I have so far: PHP Code: <script type="text/javascript"> var name = prompt("Welcome to Pick Center. Please enter your name", " "); alert("Hello " + name + "! Please look through our list of picks before placing your order."); var product = prompt("What would you like to buy?", ""); var quantity = prompt("How many " + product + " would you like to order?", ""); var confirming = confirm(""+ name + " you ordered " + quantity +" " + product +" picks. Is this correct?"); var price = " "; var item_discount = " "; if ( confirming == true ) { } else { alert("Refresh the page to reload and place a new order.")} if ( product == "dirtbag" ) { price = "5"; item_discount = "0.3";} else if ( product == "delrin" ) { price = "7"; item_discount = "0.2";} else if ( product == "speedpick" ) { price = "10"; item_discount = "0.5";} else if ( product == "stubby") { price = "25"; item_discount = "0.25";} else { alert("Sorry," + name + ". You entered an invalid product. Refresh the page to reload and place the order again.");} var cost_of_order = price * quantity; var discount = price * item_discount * quantity; var total = cost_of_order - discount; document.write("<br><h1> Your Order: </h1></br><br>"); document.write("Thank you for placing an order with us, <b>" + name + "</b>.<br><br>"); document.write("The cost of buying " + quantity + " " + product + " picks is <b>$" + cost_of_order + "</b>.<br><br>"); document.write("The discount for this purchase is <b>$" + discount + "</b>.<br><br>"); document.write("With discount, your total order cost is <b>$" + total + "</b>.<br><br>"); </script> I've tried reading around and I bought a couple of books but I just can't get a grasp on loops. Can someone please help me with this? 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? Hey everyone! I am pretty new to JS and I am having a problem figuring this loops structure out - any help would be appreciated. I am trying to add a password to an html page via an external JS file. (I know this isn't an ideal solution for securing a page - I am just trying to use this for trying to understand loops.) What I am trying to do is prompt the user to enter a password before the html page loads. If the password is correct they can enter the page. If they guess wrong the user is looped back to a prompt box to try again. If they fail 3 times they should be told via an alert box and sent off somewhere else. I have tried using a for & do while loop and was unsuccessful. I think this is the best way to go. This is what I have so far: Code: var password = prompt('All women a ',' ');
var pass1 = "Psycho";
var counter = 0;
if (counter < 3) {
if (password = pass1) {
alert('Password Correct! Click OK to enter!');
counter++
}
else {
alert("Password Incorrect!!!");
window.location="Lab5Part2.html";
}
}
else {
alert("You have failed 3 times!");
window.location="http://www.google.com";
}
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. 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">

<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 type="text/javascript">

</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 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. I'm having trouble getting this nested loop to work. It only outputs the last image and I want it to loop through the images. Code: function loadgallery (){
var picarray= new Array ()
picarray[0]="pic1.jpg"
picarray[1]="pic2.jpg"
picarray[2]="pic3.jpg"
picarray[3]="pic4.jpg"
picarray[4]="pic5.jpg"
picarray[5]="pic6.jpg"
for (j=0;j<picarray.length ;j++ ){
pic=picarray[j]
var tdarray = document.getElementsByTagName("td");
for (i=0;i<tdarray.length;i++ ){
tdarray[i].innerHTML='<select name="select1"><option value="1">1</option><option value="2">2</option><option value="3">3</option><option value="4">4</option><option value="5">5</option><option value="6">6</option></select><img src="pics/'+picarray[j]+'">';
}
}
}
window.onload=loadgallery;
How does my array look so far? thanks I think so what i was supposed to do was insert a script element that contains the function amountTotal() then add commands to the function such as 1 declare variable named total, set intial value to 0 2 create a FOR LOOP that loops all values in amount array. add current value of array item to value of total variable 3 when completed return value of total variable This is what I came up with tell me if this makes sense Thanks Quote: title>The Lighthouse</title> <link href="lhouse.css" rel="stylesheet" type="text/css" /> <script type="text/javascript" src="list.js"></script> <script type="text/javascript"> function amountTotal() { totalAmount=0; for(var i=0; i<amountTotal.length; i++){ total+=amount(i); { return total; } </script> </head> Does this seem right or is my format all wrong? if so what should i have instead? thanks |
