JavaScript - How Do I Make This Into A Loop?
I need the rolling and the displaying in a loop and i am clueless. If anyone could help it would be much appreciated.
<html> <head> <title> Die Rolls </title> <script type="text/javascript" src="http://balance3e.com/random.js"> </script> <script type="text/javascript"> function RollDice() { var roll1, roll2, roll3, roll4, roll5; roll1 = RandomInt(1, 6); roll2 = RandomInt(1, 6); roll3 = RandomInt(1, 6); roll4 = RandomInt(1, 6); roll5 = RandomInt(1, 6); document.getElementById('die1Img').src = 'http://balance3e.com/Images/die' + roll1 + '.gif'; document.getElementById('die2Img').src = 'http://balance3e.com/Images/die' + roll2 + '.gif'; document.getElementById('die3Img').src = 'http://balance3e.com/Images/die' + roll3 + '.gif'; document.getElementById('die4Img').src = 'http://balance3e.com/Images/die' + roll4 + '.gif'; document.getElementById('die5Img').src = 'http://balance3e.com/Images/die' + roll5 + '.gif'; document.getElementById('rollSpan').innerHTML = parseFloat(document.getElementById('rollSpan').innerHTML) + 1; } </script> </head> <body bgColor="lime"> <div style="text-align:center"> <p> <img id="die1Img" alt="die image" src="http://balance3e.com/Images/die1.gif"> <img id="die2Img" alt="die image" src="http://balance3e.com/Images/die2.gif"> <img id="die3Img" alt="die image" src="http://balance3e.com/Images/die3.gif"> <img id="die4Img" alt="die image" src="http://balance3e.com/Images/die4.gif"> <img id="die5Img" alt="die image" src="http://balance3e.com/Images/die5.gif"> </p> <input type="button" value="Click to Roll" onclick="RollDice();"> <hr> <p> Number of rolls: <span id="rollSpan">0</span> </p> </div> </body> </html> Similar TutorialsHi, I have this loop: Code: for (var j = 0; j < gmarkers.length; j++) {
gmarkers[j].hide();
elabels[j].hide();
map.closeInfoWindow();
var str=gmarkers[j].myname.toLowerCase();
var patt1=inp;
if (str.match(patt1))
{
found = true;
gmarkers[j].show();
count++;
var p=j;
}
}
which was useful for passing the p variable when it was just one number. but now I need to get that number every time j gets set (I understand that the j gets overwritten each time the loop goes through). What would be ideal is if p could become an array, the contents of which match the values that j has passed though during the loop cycle. I thought var p = new Array (j); minght do the trick, but obviously not... I hope that I'm explaining it OK, and that it's possible, and that somebody has an idea how to do it... I am working on a site and in the process borrowed some js from some one to get dropdown menus to work, but after a while got reports from people who tested my site of some problems and decided to verify all my code, and i have fixed most bugs but the one listed in the title. Code: sfHover = function() {
var sfEls = document.getElementById("nav").getElementsByTagName("LI");
for (var i=0; i<sfEls.length; i++) {
sfEls[i].onmouseover=function() {
this.className+=" sfhover";
};
sfEls[i].onmouseout=function() {
this.className=this.className.replace(new RegExp(" sfhover\\b"), "");
};
}
};
if (window.attachEvent) {window.attachEvent("onload", sfHover);}
and i am verifying it on jslint the error i get is: Quote: Error: Problem at line 6 character 10: Don't make functions within a loop. }; Problem at line 9 character 10: Don't make functions within a loop. }; Implied global: sfHover 1,12, document 2, window 12 any help will be appreciated, and I'm sure this isn't complex but i don't know much js and want to keep it the same. 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;
}

function findIndexOf(number, numberArray)
{
var indexWhereFound = -1;
for (var position = 0; position < numberArray.length; position = position + 1)
{
if (numberArray[position] == number)
{
indexWhereFound = position;
}
}
return indexWhereFound;

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... Code: var reportArray=new Array();
var reportData, title, subTitle, data;
for(i in parmarray)// loop thru AuditTable array and get values
{
title = '<div style="font-family:verdana; font-size:14px; font-weight:bold; margin:25px 0px 5px 30px">';
title += namearray[i][0];
title += '</div>';
reportArray.push(title);//Take compiled variable value and put it into array
for(j=0; j < AuditTable[0].length; j++)// loop thru AuditTable array and get values
{
subTitle = AuditTable[0][j];//points to first row of AuditTable where the labels are
data = AuditTable[1][0];//points to the current row where actual data is
html = i + j +'<div style="font-family:verdana; font-size:12px; color:#696969; font-weight:bold; margin-left:30px;">';
html += subTitle;
html += '</div><div style="font-family:verdana; font-size:12px; color:#a9a9a9; margin-left:30px; margin-bottom:10px">';
html += data;
html += "</div>";
reportArray.push(html);// put results into array
}
}
it wont loop, as long as you enter something in the name field it will submit. also how do i stop from submitting if all fields are not filled out? any help will be appreciated) ====== function checkForm(form) { var len = form.elements.length; var h=0; for (h=0; h<=len; h++){ if ((form.elements[h].value==null) || (form.elements[h].value=="")){ alert("Please enter "+document.myForm.elements[h].name); document.myForm.elements[h].focus(); return false; } return true; } } ===body-== <FORM NAME="myForm" METHOD="post" ACTION="http://ss1.prosofttraining.com/cgi-bin/process.pl"> Name:<BR> <INPUT TYPE="text" size="30" NAME="name"><br> Email address:<BR> <INPUT TYPE="text" size="30" NAME="email address" onBlur="emailTest(this);"><br> Phone number:<BR> <INPUT TYPE="text" size="30" NAME="phone number"><br> Fax number:<BR> <INPUT TYPE="text" size="30" NAME="fax number"><p> <INPUT TYPE="submit" VALUE="Submit Data" onClick="return checkForm(this.form);"> <INPUT TYPE="reset" VALUE="Reset Form"> </FORM> Hi, I am doing some studying and we was to create a small loop using either the for loop, while loop or do while loop. 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? 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. 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 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! 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 = '';
}
}
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 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!
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 So I have a spreadsheet he GoogleDocs The code I have is : Code: function addition() {
// Declare Variables
var inputCell, outputCell, tempValueHolder;
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheets()[0];
// Declare the range of the input numbers: Column C
var inputRange = sheet.getRange("C4:C41");
// Declare the Range of where you want the output numbers: Column D
var outputRange = inputRange.offset(0, 1);
// Calculate the column and row count. columns = 1, rows = 37
var colNum = inputRange.getNumColumns()-1;
var rowNum = inputRange.getNumRows()-1;
// Run the for loop
// There is only one column of data, C
for (var i=0; i<=colNum; i++);
{
// There are 37 rows of data, 4 through 41
for (var j=0; j<=rowNum; j++);
{
// Declare column and row info for cells
inputCell = inputRange.getCell(j,i); //from Column C
outputCell = outputRange.getCell(j,i); // to Column D
// Copy whatever is in Column D
tempValueHolder = outputCell.getValue();
// Set Column D's cell to be whatever is in Column C PLUS what WAS in Column D
// It's just adding Column C's value to Column D's
outputCell.setValue(inputCell.getValue()+tempValueHolder);
// Clear Column C
inputCell.clearContent();
// next row (supposedly)
}
}
}
What I'm trying to do is take Values entered in the C column and add them to the existing number in column D of the same row. I do this from the starting cell: C4 down the rows to C41. Again, taking the value in C4 and adding it to D4... or C4+D4=newD4, all the way down to row 41. So here's the problem. Whenever I run the function it only completes the last line in the loop, as in the last row (41). If I change the range from C4:C41 to C4:C#, it always only completes the loop with the # row. I can't figure out why. I have spent 6 hours JUST on this problem. Please someone with more knowledge help me. Thank you. apparently this is supposed to be a loop... I got it off another topic here and it made NOOOO sense Code: //dandavis's ES5 Array methods:

function fader(obj) {
var div = document.getElementById(obj);
//Object details
var opacity = div.style.opacity * 100 + fadeBy; //Fade (FF)
ie_counter = ie_counter + fadeBy;
var opacity_ie = div.style.filter = "alpha(opacity=" + ie_counter + ")"; //Fade (IE)
div.style.opacity = opacity / 100;
if ( ie_counter != fade_to || opacity != fade_to ) {
setTimeout( "fader('" + obj + "')", fadeTime );
}
}
The loop stops for firefox (good browser), but not for internet explorer for some reason :/ Apart for the fact that IE is crap why is this? Hi all, The following code is an assigment.I have it running with out any errors.It has to take the array (arrayToshuffle) and through running though the end of the (arrayToshuffle) the string has to be shuffled.We havent learnmt shuffle() yet.) I think the problem is these lines. arrayToShuffle[index]=arrayToShuffle[swapIndex]; arrayToShuffle[swapIndex]=arrayToShuffle[index]; But no matter what varibles I put in these lines and how much i fiddle I carnt seem to get it to run without repeating the same elements in the output. I dont want anyone to fix it for me just advise on where I could look for problems. Am i missing somthing here? Heres the program if you run it you will see what I mean. <html> <head> <script> var arrayToShuffle = new Array('Ace','2','3','4','5','6','7','8','9','10','Jack','Queen','King'); var arraySize = arrayToShuffle.length; document.write('<h1>Array shuffling</h1>'); document.write('<p>Before shuffle: '+arrayToShuffle+'</p>'); SWAPS_TO_MAKE = 30; var index=0; var self_swaps=0; var counter = 0; while(counter < SWAPS_TO_MAKE) { var swapIndex = Math.floor(Math.random()*arraySize+1); arrayToShuffle[index]=arrayToShuffle[swapIndex]; arrayToShuffle[swapIndex]=arrayToShuffle[index]; if(index =swapIndex) { self_swaps++; } counter++; index = (index+1 % arraySize); } document.write('<p>After shuffle: '+arrayToShuffle+'</p>'); document.write('<ul>'); document.write('<li>Swaps made: '+SWAPS_TO_MAKE+'</li>'); document.write('<li>Self swaps: '+self_swaps+'</li>'); document.write('<li>Effective swaps: '+(SWAPS_TO_MAKE-self_swaps)+'</li>'); document.write('<li>Effective rate: '+((SWAPS_TO_MAKE-self_swaps)/SWAPS_TO_MAKE)+'</li>'); document.write('</ul>'); </script> </head> <body> </body> </html> Thanks heaps Shayne Darcy Need to write a script that will ask for password and then give an alert with either successful login or unsuccessful login. It needs to use the while loop and I need for the script to accept four different passwords. I can script it for one password but can not figure out how to get it to work for other the passwords. Unfortunately I don't know computer programming and very little html and was allowed to sign up for a course that is too advanced for me and I can't drop it because I will lose my financial aid so with I am really struggling in this class and the assignments do not really go with the textbook and examples provided. Here is the code I have so far: <html> <body> <script type="text/javascript"> var password = new Array ("midland", "baycity", "saginaw", "delta"); var tries = 3; password = prompt("Enter password", ""); while (password != "midland" && tries > 0) { alert("Incorrect password - You have " + tries + " more tries"); password = prompt("Enter password", ""); tries--; } if (password == "midland") alert("Login Successful"); else alert ("Login Failed - Please Try Later"); </script> </body> |
