JavaScript - Redraw Element Within For Loop

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;
}

/*
*searches for a number in a number array.
*
*function takes two arguments
*	the number to search for
*	the  number array to search
*function returns the array index at which the number was found, or -1 if not found.
*/
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;
}

//ARRAYS that represent the board -- you do not need to change these
//array of special squares
var specialSquaresArray = [1,7,25,32,39,46,65,68,71,77];
//array of corresponding squares the player ascends or descends to
var connectedSquaresArray = [20,9,29,13,51,41,79,73,35,58];

//VARIABLES used -- you do not need to change these
//the square the player is currently on
var playersPosition;
//play is initially at START
playersPosition = 0;

//what they score when they roll the die
var playersScore;

//the index of the player's position in the special squares array or -1
var indexOfNumber;

//MAIN PROGRAM

//TODO add code here for parts (iii), (iv)(b), (v), and (vi)
// start of question(iii)
playersScore = rollDie();
	document.write(' Sco  ' + playersScore);
playersPosition = playersScore + playersPosition;
	document.write(', Squa  ' + playersPosition);

indexOfNumber = findIndexOf(playersPosition, specialSquaresArray);

if (indexOfNumber != -1)
{
	document.write(', Ladder to Squa  ' + connectedSquaresArray[indexOfNumber]);
	playersPosition = connectedSquaresArray[indexOfNumber];
	indexOfNumber = -1;
}
document.write('<BR>')
// end of question(iii) 

// start of question(iv)(b) 
while(playersPosition<=80)


{
playersScore = rollDie()
	document.write(' Sco  ' + playersScore)
playersPosition = playersPosition + playersScore
	document.write(', Squa  ' + playersPosition)
indexOfNumber = findIndexOf(playersPosition, specialSquaresArray)


if(indexOfNumber != -1)
{
	document.write(', Ladder to Squa  ' + connectedSquaresArray[indexOfNumber]);
	playersPosition = connectedSquaresArray[indexOfNumber];
}	
	document.write('<BR>');
}
var countMoves = 0;
while(countMoves <= 0)
{
	document.write('You took ' + countMoves + ' moves to get out');
	countMoves = countMoves + 1
}	

/*for (var countMoves = 0; countMoves < playersPosition; countMoves = countMoves + 1)
{
	countMoves = countMoves + playersPosition;
	document.write('You took ' + countMoves + ' moves to get out');

}*/




// end of question(iv)(b) 

// start of question (v) 
/*if (playersPosition >=80)
{
	document.write('The player is out');
}*/
// end of question (v)

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
			}		
		}

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?

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)

Hi,

(new to javascript)

Code:

digAudio = document.createElement("audio");	
	digAudio.setAttribute('src',hypeDocument.documentName()+'_Resources/'+'digging.m4a');
	digAudio.id = "diggingAudio";
	newAudio = document.getElementById("diggingAudio"); //returns null

the audio element is added (I can play the audio) but I can't get it by its id ?

thank you

I have the following code

Code:

<div class="thdnrml">
<td><a href="somelink">fonfof</a></td>
</div>

what i want to do is this:
Code:

<div class="thdnrml">
<td><a href="somelink">fonfof</a><a href="anotherlink">another_link</a></td>
</div>

how can i go about achieving this?

Alright, this is going to sound strange, but bear with me here...

Code:

<input type="text" name="_F0827U" size="015" maxlength="015"> &nbsp; <input type="submit" class="cmdkey" name="_K040827" value="...">

Say I have multiple isntances that look similar to the above. However, I have no possible way of identifying them uniquely (because I don't know the name prior to generation). Is it posable, using JS, to snag the previous element and strip it of it's tags then rewrite a new element isntead of the two originals, say using an onClick() event on either of the elements?

I am using a jQuery slider for a website but the W3C comes up with invalid because:

document type does not allow element "div" here
.before('<div id="buttons">')

Code:

<script type="text/javascript">
$(document).ready(function() {
$('#slider')
.before('<div id="buttons"></div>')
.cycle({
fx: 'fade', // choose your transition type, ex: fade, scrollUp, shuffle, etc...
pager:  '#buttons'
});
});
</script>

Any help with this would be appreciated thanks.

hi All,

I want to add UL item to Li in java script dynamically .so that i can build submenu dynamically.can any one help me.

Hello. I am setting up a simple registration page for a community arts project, but I am new to JS and having some issues. Right now I have a list of check boxes like this:

Code:

<input type="checkbox" id="HA0001" onclick="updateTotal()" /> Wendy Day
<input type="checkbox" id="HA0002" onclick="updateTotal()" /> Al Benne
<input type="checkbox" id="HA0003" onclick="updateTotal()" /> Julie Steppe

What I would like to do is GET the input boxes ID value - which will be different for every checkbox. That value will correspond with a variable of the same name in my javascript code, that will be added or subtracted from the users total cost.

So when a box is clicked, I need my variable (called "currentId") to update to the ID value, such as "HA0001" - etc. I was thinking something along the lines of this, but I know it is incorrect:

Code:

var currentId = document.getElementById.id;

All the other add/subtract stuff I will figure out, but I am having a problem getting the ID value from a checkbox when it is clicked. Can anyone help me figure this out?

THANKS!
-AJ

I am trying to have it so that when someone choose a value from the select box, it then displays it in the html. The problem is im not very good with javascript, and my error keeps coming up as undefined where as before it was coming up as "[object HTMLSelectElement]". Can anyone tell me whats up?

PHP Code:
<html>
<head>
<script type="text/javascript">
function moveValue()
{
var no=document.getElementById("no");
var option=no.options[no.selectedIndex].numberr;
document.getElementById('numberr').innerHTML = option;

}
</script>
</head>

<body>
<form>
Select numbers:<br />
<select id="no">
    <option>0</option>
    <option>1</option>
    <option>2</option>
    <option>3</option>
    <option>4</option>
    <option>5</option>
    <option>6</option>
    <option>7</option>
    <option>8</option>
    <option>9</option>
</select>
<input type="button" onclick="moveValue()" value="-->">
<i id="numberr">Testing</i> 

</form>

</body>
</html> 


and now that i look at it, i suspect that the reason that it is not working is that i should have "ID"'s or value's on each of the options but i do not know for certain

Hi,
Would someone here please help me with this script. I know I am a complete hack at this, but I need to get it to work. Your help is appreciated.

As you can see, based on the if statement, I need to leave the Div element below hidden, or un-hide it.

I know the first part works. The second part (after "else" ) is where I am having the problem.
Code:

<td>
<script type="text/javascript">
if ([fieldXX]==1)   
 {
 document.write("<a href='page1.asp?itemid=1234'><img src='images/btn-choose.gif' border='0' alt='choose button'</a>"); 
 } 
else
 {  
    var id = 'hide-buy-btn';
    var item = document.getElementById(id); 
 if (item) {
 item.className=(item.className=='hidden')?'unhidden':'hidden';
 }
 }
</script>

<div id="hide-buy-btn" class="hidden">
x
xother button code
x						
</div>
</td>

Ok, Simpler question. I'm trying to get the text in an xml element. Instead of getting just the text in the first child element I'm getting the text of all the children elements. How can I get it from just the first?

Code:

     var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
     
     function xmlload(filexml) 
       { 
         xmlDoc.async="false"; 
         xmlDoc.load(filexml); 
         xmlObj=xmlDoc.documentElement; 
      }
      
      xmlload('urlhere');
      
      document.getElementById("nmbr").value=myVar;
      myVar = xmlObj.childNodes(0).childNodes(19).firstChild.text;

      document.getElementById("comment_t").innerText= myVar;

I know for sure that lastRowTD_s[i] does not have "textarea" element !
The whole page is html valid.

Code:

      else if (lastRowTD_s[i].getElementsByTagName('textarea'))
      {
        
        alert(lastRowTD_s[i].id);
        //checked, it is the row that does not have "textarea" element. 

        alert(lastRowTD_s[i].getElementsByTagName('textarea'));
        // gives me [Object HTML collection]  !?

        alert(lastRowTD_s[i].getElementsByTagName('textarea')[0]);
        //gives me "undefined", heh where has it gone since previous line ?
      }
