JavaScript - For Loop Question
How do I re-write this from VBA to JAVASCRIPT?
Code: For i = 0 To num_fields - 1 Forgive me, im still new at this stuff. Thanks. Jay Similar TutorialsSo I am wanting to loop through a set of data an undefined amount of times. For this I need a while loop. However, I want the loop to check for the given condition and continue looping on true, but when it breaks on false - to then execute a different command. Code: while(localStorage.getItem(x) != null)
{
x++;
if(localStorage.getItem(x) == null)
{
localStorage.setItem(x, account.join(";"));
break;
}
}
}
This works by continuing to loop everytime with the x++ and the nested if statement inside. The problem gets messier as now I need to perform a separate while loop around the entire thing checking for a different condition. To sum things up, what is the most efficient way to perform a while loop and have one action be performed on success and another if it breaks or reaches a defined condition. I have a dice rolling function. The user enters the number of sides, and the dice rolls 36000 times. I track the results, and then display the percentages of each number being rolled as well. I have it to where it displays but only for ONE die ( eg : a 5 sided die, it only displays up to 5, and not 10 ) But the function is rolling for both die, just not displaying. I'm thinking I need to change, in the rollDice function, <=d.side to <=rolled_value, but whenever I do this, I get NaN errors. Any help would be appreciated! Code:
<script type="text/javascript">
function Die(side) {
this.side = side;
this.roll = function () {
var result;
result = parseInt(((Math.random() * 1000) % this.side) + 1 );
return result;
}
// <![CDATA[
this.validateNum = function (side) {
if (side > 1 && side < 101)
return true;
else
return false;
}
}
function rollDice() {
var d = new Die(document.getElementById('number').value);
if (d.validateNum(d.side) == true) {
var numCount = new Array(d.side);
var percent;
var rolled_value;
for (var i=1; i<=d.side; i++)
numCount[i] = 0;
for (var j=0; j<36000; j++) {
rolled_value = d.roll() + d.roll();
numCount[rolled_value] = numCount[rolled_value] + 1;
}
for (var k=1; k <= d.side; k++)
document.writeln("Number of" + " " + k +"'s" + " " + "rolled" + ' : ' + numCount[k] + '<br/>' );
for (var l = 1; l <= d.side; l++) {
percent = new Number(parseFloat(numCount[l] / 36000) * 100).toFixed(2);
document.writeln("Percentage of" + " " + l + " " + "being rolled" + ' : ' + percent + '% <br/>');
}
}

Hello, This seems like it should be extremely easy, I think I am missing something fundamental however. First, I have some XML: Code: <aaaaag> <parent text="this is the parent 0"> <child text="zero" /> <child text="one" /> <child text="two" /> <child text="three" /> <child text="four" /> <child text="five" /> </parent> <parent text="this is the parent 1"> <child text="zero" /> <child text="one" /> <child text="two" /> <child text="three" /> <child text="four" /> <child text="five" /> </parent> </aaaaag> And here is a snippet of my js: Code: aaaaag = xmlDoc.getElementsByTagName("aaaaag");
var x = aaaaag[0].childNodes[1].childNodes;
cCompA.innerHTML = aaaaag[0].childNodes[1].attributes.getNamedItem("text").nodeValue;
// I would have expected childNodes[0] instead !!
for (i=1;i<x.length;i+=2)
// I would have expected: (i=0;i<x.length;i++) instead !!
{
cCompB.innerHTML = x[i].attributes.getNamedItem("text").nodeValue + "<br />";
}
I really have two questions here, but the first may answer the second. Also it may be worth mentioning I am just trying to work with the "parent 0" for the moment. First, I seem to have hidden nodes in my XML. When accessing the first child as an object, the index is 1, the second is 3 (I have tested this by manually putting in 1,3,5,7,9 etc as the indexs) and so on, rather than starting at 0. I'm not seeing where the hidden nodes are though, and I've run my xml through a validator on W3Cschools.com. I've seen someone recommend not using attributes and instead using a <text>one</text> format, but I am really hoping this isn't the problem as my xml file is fairly long, and it would take quite a bit of effort to rewrite it. The second question is, my for loop only outputs the last child, rather than all the previous children. If anything, I would really expect the last one NOT to get output, because of the i+=2 I am having to do because of the hidden children problem. I'm guessing this is somehow related to the first problem though. Thanks in advance! I have done a basic while loop code but I can not figure out how to make the output print in 4 lines containing 5 numbers each. Can anyone tell me how to specify the number of output that appears on each line? Code: <?xml version="1.0" encoding="UTF-8"?>

I was wondering what the best way to make a smaller simpler version of this code is? Would it be using a loop? If so can you help me with how to I have a simple issue that I cannot fix. The code bellow, is a while-loop with RGB color. It displays the word Hello 10 times id 10 different colors. The problem is I cannot get the correct colors displayed. I want the first Hello to be red and end up green in the last one. For some reason I cannot get the color combination correct, even after I put 255 for red and 192 for green. Can you please have a look and tell me what am I doing wrong?

Hello, In the below script syntax, a simple table converts Celsius degrees into Fahrenheit, using the For loop and integrating it into a table. Code: <html>
<head>
<title>Celsius-Fahrenheit Converter</title>
</head>
<body>
<table border=3>
<tr><td>CELSIUS</td><td>FAHRENHEIT</td></tr>
<script language="javascript">
for (celsius=0; celsius<=50; celsius=celsius+1)
{
document.write("<tr><td>"+celsius+"</td><td>"+((celsius*9/5)+32)+"</td></tr>");
}
</script>
</table>
</body>
</html>
My questions are about the following script inside the <td> tags: <td>"+celsius+"</td> <td>"+((celsius*9/5)+32)+"</td> 1) why is the script inside the above <td> tags placed between " " ? 2) why is the script inside the above <td> tags placed between + + ? Thanks a lot for your explanation to an absolute Javascript beginner...! Ok, I'm nearly pulling my hair out with this one. I have been looking at this code for two evenings now, and rewrote it 4 times already. It started out as jQuery code and now it's just concatenating strings together. What I'm trying to do: Build a menu/outline using unordered lists from a multidimensional array. What is happening: Inside the buildMenuHTML function, if I call buildMenuHTML, the for loop only happens once (i.e. only for 'i' having a value of '0'.) If I comment out the call to itself, it goes through the for loop all 3 times, but obviously the submenus are not created. Here is the test object: Code: test = [
{
"name" : "Menu 1",
"url" : "menu1.html",
"submenu" : [
{
"name" : "menu 1 subitem 1",
"url" : "menu1subitem1.html"
},
{
"name" : "menu 1 subitem 2",
"url" : "menu1subitem2.html"
} ]
},
{
"name" : "Menu 2",
"url" : "menu2.html",
"submenu" : [
{
"name" : "menu 2subitem 1",
"url" : "menu2subitem1.html"
},
{
"name" : "menu 2subitem 1",
"url" : "menu2subitem1.html"
} ]
},
{
"name" : "Menu 3",
"url" : "menu3.html",
"submenu" : [
{
"name" : "menu 3 subitem 1",
"url" : "menu3subitem1.html"
},
{
"name" : "menu 3 subitem 1",
"url" : "menu3subitem1.html"
} ]
}
];
Here is the recursive function: Code: function buildMenuHTML(menuData,level) {
var ul;
if (level == 1) {
ul = "<ul id='menu'>";
} else {
ul = "<ul class='level" + level + "'>";
}
for (i = 0; i < menuData.length; i++) {
menuItemData = menuData[i];
ul += "<li>";
ul += "<a href='" + menuItemData.url + "'>" + menuItemData.name + "</a>";
if (typeof menuItemData.submenu != 'undefined') {
ul += buildMenuHTML(menuItemData.submenu,level + 1);
}
ul += "</li>";
}
ul += "</ul>";
return ul;
}
Here is how the function is called initially: Code: buildMenuHTML(test,1); This is it's return value (with indentation added for readability): Code: <ul id='menu'>
<li><a href='menu1.html'>Menu 1</a>
<ul class='level2'>
<li><a href='menu1subitem1.html'>menu 1 subitem 1</a></li>
<li><a href='menu1subitem2.html'>menu 1 subitem 2</a></li>
</ul>
</li>
</ul>
'Menu 2' and 'Menu 3' don't show up! I'm sure it's something small that I'm overlooking, but any help would be appreciated. Hi all I'm well aware that I can't post assignments here and expect an answer, however, I have been staring at this code for so long. I feel I am close to the solution (to get the correct output to the browser) but I just cannot get it to count how many moves it takes. I don't want an answer, but a nudge in the right direction would be very grateful. As you can see from the code and the output, it will attempt to write to the browser how many moves, but only '0'. Code: function rollDie()
{
return Math.floor(Math.random() * 6) + 1;
}
/*

{
var indexWhereFound = -1;

Many thanks. Hello... Thanks for reading... I am getting an undefined error when i try to get a value from this array in the interior loop... Code: // This is the array I am trying to access AuditTable [0] = ["Visio Modifed date","Word Modified Date","User Status","User Comment","Last Audit","Audit Status","Audit Comment"] AuditTable [1] = ["11/23/2009 8:52:18 AM","missing","OK","user comment number 1","1/1/2009","ok","audit comment number 1"] AuditTable [2] = ["11/24/2009 12:21:19 AM","missing","Out of Date","Changes from 2008 not implemented","1/2/2009","Out of Date","needs update"] AuditTable [3] = ["11/22/2009 9:24:42 PM","missing","Incomplete","Document doesnt cover all possibilities","1/3/2009","Inadequate","needs update"] I have hard coded values and had success such as: Code: data = AuditTable[1][0] But when I put the vars associated with the loop in I get an undefined error - AuditTable[i] is undefined: Code: // produces error data = AuditTable[i][j] //Works but retrieves wrong data data = AuditTable[j][i] //Works but retrieves wrong data data = AuditTable[1][i] //Works but retrieves wrong data data = AuditTable[j][2] I must be trying to access the array incorrectly or something... I have defined all the vars, and tried many combinations, alerted the values of both vars so I can prove it is not a scope issue... Am I missing something obvious? Thanks much...

I chose to do the for loop because it was easier to understand, but I want to know how to do the same using the while loop. Here is the for loop I have, but I cant figure out how to change to while loop. Code: for (var i = 0; i < 5; ++i)
{
for (var j = i; j < 5; ++j)
{
document.write(j + "");
}
document.write("<br />");
}
output is equal to: 01234 1234 234 34 4 How do you make the same using a while loop? Hi All, im trying to to use a for loop to loop through a drop down list of users and if there is a match between the user logged in and the drop down list i want to enable two fields, if the user logged in isnt in the drop down list i want to disable the two fields, but im having trouble looping through, iv tried ".value" with no avail.. heres my Script Code: var RequestingUser = document.getElementById('JoinersLeaversContent_cmbRequestingUser').text;
var Authorisers = document.getElementById('JoinersLeaversContent_ddlAuthoriseId');
for (var i = 0; i < Authorisers.length; i++)
{
if (RequestingUser.text == Authorisers.value) {
document.getElementById('JoinersLeaversContent_txtAuthoriserSig').disabled = false;
document.getElementById('JoinersLeaversContent_txtDateSignedOff').disabled = false;
}
else
{
document.getElementById('JoinersLeaversContent_txtAuthoriserSig').disabled = true;
document.getElementById('JoinersLeaversContent_txtDateSignedOff').disabled = true;
}
}
So just to be clear, if the user logged in appears in the drop down box i want to enable the two fields, if they dont appear i want to disable the two fields Please help. Thank you I have the following code which is almost completely working the way I need it to with the exception of the "downloadFile" value... Code: /*Regex list of download file extensions, pipe and backslash delimited. Looks for the period before the file type so it will work on download links with query parameters after it */
var downloadTypes = /\.pdf|\.doc|\.xls|\.zip|\.csv|\.ppt|\.rtf|\.pptx|\.docx|\.xlsx|\.wmv|\.mpg|\.exe|\.mp3|\.rar|\.wav/i;
/*Regex list of on-site domains, pipe and backslash delimited. */
var onsiteDomains = /\mytestdomain1\.com|\mytestdomain2\.com|javascript|#/i;
/*Used to unobtrusivly add events to objects*/
function unobtrusiveAddEvent (element,event,fn) {
var old = (element[event]) ? element[event] : function () {};
element[event] = function () {fn(); old();};
}
var links = document.links;
if ( links ){
for(var i=0; i<links.length; i++) {
if( links[i].href.match(downloadTypes) ){
unobtrusiveAddEvent( links[i], 'onclick' , function() { ntptEventTag('ev=download&eventPage=Download From: ' + escape( wa.currentDomain + wa.currentURL ) + '& downloadFile=' + escape( links[i] ) ); });
}
if( !links[i].href.match(onsiteDomains) ){
unobtrusiveAddEvent( links[i], 'onclick' , function() { ntptEventTag('lk=1&ev=Exit Link'); });
}
}
}
...how do I grab the value of the href that was just clicked? links[i] is not working (it's just grabbing the href value of the last href in the loop). I am missing something simple for sure. Can anyone point out what I am missing? Thanks! Hey guys i've just been following a few tutorials and learnt how to do a for loop and a while loop, what is the major difference between the two? they seem quite similar? I know while loops are laid out a hell of a lot easier in my opinion!
For those who read my other thread I finally scratched together the code to take a value from an XML file and add it to a select box as an option. Ofcourse it only does it once so I need to loop it. It's kinda complex though, here's a function line to add one option: addOption(document.people_form.People,name2,office2) And here's the code in the head: <script type="text/javascript"> //load xml file if (window.ActiveXObject){ var xmlDoc = new ActiveXObject("Microsoft.XMLDOM"); xmlDoc.async=false; //Enforce download of XML file first. IE only. } else if (document.implementation && document.implementation.createDocument) var xmlDoc= document.implementation.createDocument("","doc",null); if (typeof xmlDoc!="undefined") xmlDoc.load("namedata.xml"); //Regular expression used to match any non-whitespace character var notWhitespace = /\S/ function getnames(){ //Cache "messages" element of xml file var nameobj=xmlDoc.getElementsByTagName("list")[0] //REMOVE white spaces in XML file. Intended mainly for NS6/Mozilla for (i=0;i<nameobj.childNodes.length;i++){ if ((nameobj.childNodes[i].nodeType == 3)&& (!notWhitespace.test(nameobj.childNodes[i].nodeValue))) { // that is, if it's a whitespace text node nameobj.removeChild(msgobj.childNodes[i]) i-- } } } if (typeof xmlDoc!="undefined"){ if (window.ActiveXObject) //if IE, simply execute script (due to async prop). getnames() else //else if NS6, execute script when XML object has loaded xmlDoc.onload=getnames } var name2=xmlDoc.getElementsByTagName("name")[0].firstChild.nodeValue; var office2=xmlDoc.getElementsByTagName("office")[0].firstChild.nodeValue; var officePH2=xmlDoc.getElementsByTagName("officePH")[0].firstChild.nodeValue; var mobile2=xmlDoc.getElementsByTagName("mobile")[0].firstChild.nodeValue; var email2=xmlDoc.getElementsByTagName("email")[0].firstChild.nodeValue; </script> <script type="text/javascript"> function addOption(selectbox,text,value ) { var optn = document.createElement("OPTION"); optn.text = text; optn.value = value; selectbox.options.add(optn); } </script> Could anyone give me a pointer on how to loop this so that it loads one option after another from the XML file? Thanks. I have a form that shows or hides divs based on what is chosen in a dropdown. There are 4 divs but only one is shown and the other 3 hidden based on dropdown selection. Inside each div are checkboxes with items for sale. I want to reset the checkboxes to unchecked and the line total values to 0 if the div is hidden. I've got the checkboxes to reset but I can't figure out how to set the line total values to 0 (There are 14 total so I'm trying to loop thru all of them and reset them.) This is what I have in the loop Code: for (var i = 0; i < form.elements.length; i++ ) {
if (form.elements[i].type == 'checkbox') {
form.elements[i].checked = false;
}
}
// set line_totals to 0
for (var j = 0; j< form.elements.length; j++ ) {
if (form.elements [j].name.substring(0,10) == 'line_total') {
form.elements[j].value = '';
}
}
Hello, I recently purchased a JavaScript book, and I am confused by one of it's examples. I was wondering if anybody could answer my question. Here is the example: for (loopCounter = 1; loopCounter<= 3; loopCounter++) { //execute this code } Now, what I need help with is the variable part. The book goes on to say: ""To keep track of how many times you have looped through the code, you need a variable to keep count" My question is: Why does the variable have the value of one and not another number? I'm very very new to JS, I understand that the loopCounter has to be les than or equal to 3 for the code to execute, and also that it is incremented by one each loop, but the book is not clear on why the value of the variable has been set to 1. If anybody could answer this question I would be very grateful, I hate moving onto the next stage of a book if I do not completely understand the previous topics. Thank you in advance Hello all. I am faitly new at programming and have run into a little problem. I want to create a script that creates 2 random numbers, stored in 2 different variables and then compare them to eachother. there is two possible outcome of that comparison, either they are different or they are alike. If they are different i want to randomize a new set or numbers and make a other comparement, also to keep track on how many times i have created numbers. If they are alike i want to display the numbers and how many tries it took to get a matching pair. atm it looks like this <html> <body> <script> var x=(Math.floor(Math.random()*6)+1); var y=(Math.floor(Math.random()*6)+1); //creates two random int between 1 and 6 var throws = 1; //keep tabs on how many times we have thrown the dices if(x!=y) { x=(Math.floor(Math.random()*6)+1); y=(Math.floor(Math.random()*6)+1); throws=throws+1 }else{ document.write("you have rolled a pair. Dice 1 is: " +x +" and Dice 2 is: " +y +" and it took " +throws +" tries to get a pair."); } </script> </body> </html> How to get that into a loop? a really confused newbie scripter |
