JavaScript - Javascript Multi Dimensional Arrays

Hi,

I'm having trouble figuring out why my image is disappearing when the user clicks on the arrow image to expand text for viewing. The arrow image only disappears if the link text is is more than one line. It remains if the link is only one line of text. Here is the code:


HTML code:
Code:

<div class="ws-webpart>

<div class="hidecat1"></div>

Hi i am confused in one topic and need help,

I have a javascript array containing objects like;
Object values are ordered as Type, Amount and count.

Object 1 => ("A" , 100 ,10)
Object 2 => ("C" , 50 ,10)
Object 3 => ("A" , 100 ,20)
Object 4 => ("B" , 200 ,10)
Object 5 => ("A" , 10 ,10)
Object 6 => ("B" , 100 ,10)
Object 7 => ("C" , 100 ,5)
Object 8 => ("C" , 50 ,5)

In the end i want to group these objects like ;

("A" , 100,30) (Note : 30 = 20 +10)
("A" , 10,10)


("B" , 200,10)
("B" , 100,10)


("C" , 100,5)
("C" , 50,15) 15 = 10 + 5


How can i do this in javascript, note that the new types will be added to this array ?

Hi, I'm kinda newbie in javascript and would really like some help if you wouldn't mind?

I'm working with dreamweaver and VBScript and have drop down lists being populated by dynamic recordsets, the tables that are being used are text fields and everything is working fine other than one niggly thing I want to do and just don't seem to be able to get the javascript code right

The data I have has two columns; area and technical issue. As the area contains duplicates I have this as a separate drop down list with a distinct
in the sql command and from an onclick event from the 'area' drop down list, I get the value of the selected item

[var x = document.NewFacilityAdminDetailsTest.ara_component.selectedIndex;
var ara_component = document.NewFacilityAdminDetailsTest.ara_component.options[x].value;]


all's well so far....

The second drop down list contains all the 'technical issues' which is great, BUT because its a dynamic recordset its for ALL of the areas and I want to be able to take away the technical issue values in the technical issues drop down list that don't belong to the area that's been picked and I also dont' want the user selecting a technical issue that isn't linked of the area.

I've tried some of the samples I've found by googling and even the adobe example but they all seem long winded and I never quite get the code right and the second drop down list just keep showing ALL 'technical issues show' for ALL of the 'areas'.

Surely there's a bit of javascript to turn the second drop down list recordset into an array, loop through the array and remove the technical issues that don't match the selected value from the 'area' drop down list and put the array into the second drop down list instead of using the recordset?

Any help would be soooooo useful.

Ok so this is probably a simple question but i have hit a wall he

So I have 20 arrays with incremental names (course1, course2, course3 ...)
What i want to make is a selection box with 20 options.
for each option the value would be course1[0] and the text shown would be course1[1].
if i write this code:

<code>
for (var i=1; i<=20; i++){
var select = document.getElementById("selectiontest")
select.options[select.options.length] = new Option (course1[1], course1[0])
}
</code>

The code works and the correct array values are put as the option text and value. I am having trouble getting the loop to move from course1 to course2, i used the loop counter in the array name like this:

<code>
for (var i=1; i<=20; i++){
var select = document.getElementById("selectiontest")
select.options[select.options.length] = new Option (('course'+i)[1], ('course'+i)[0])
}
</code>
this is where it stops working. I get 20 values of o. which i assume is the second character of course. How do i tell javascript to incrementally change the array name during the loop?

Any suggestions on how the javascript below should be changed so it will work with checkboxes that have brackets in the name? (I'm using foreach in php, and can't seem to get the php to work/work correctly without using them.)

Thanks!

Code:

function chktotal(j) {
var total=0;
for (var i=0; i < document.form1.ckbx.length; i++){
if(document.form1.ckbx[i].checked){
total=total+1;
}


if(total>8){
alert("Please only select 8");
document.form1.ckbx[i].checked = false;
total = total -1;
return false;
}
}
document.form1.totalval.value = total;
}


<input onclick="chktotal(2)" value ="Sample Item 1"  type="checkbox" name="ckbx[]">

I'm working on this website and some contents are set up in arrays. How do you refer variables to work with arrays. I need the correct syntax.

I'm trying to do this using numerical arrays for an assignment:

Create a webpage with three select boxes. If basketball is selected in the first select box, the second select box should display the names Celtics, Lakers, and Bulls. If Celtics is selected from the second select box, the third select box should display the names Larry Bird, Bill Russell, and Kevin McHale.

I think i have a good start but i can't seem to get the fields to automatically populate with the players. This has to be done solely with JavaScript. Any help would be greatly appreciated?

Hi,
I'm new to JS and I am trying to build my first script. My problem, is I'm trying to build a multi hide/show script, displaying paragraphs of information. If I want multiple variables for the script do I have to use an array? and if so, how can I construct this array?

Here is my script as of now,

<!--
// this tells jquery to run the function below once the DOM is read
$(document).ready(function() {


// choose text for the show/hide link
var showText="Resume";
var hideText="Hide";
var profile_showText="Profile";
var profile_hideText="Hide";

// append show/hide links to the element directly preceding the element with a class of "toggle"
$(".toggle").prev().append(' (<a href="#" class="toggleLink">'+showText+'</a>)');
$(".profile_toggle").prev().append(' (<a href="#" class="profile_toggleLink">'+profile_showText+'</a>)');


// hide all of the elements with a class of 'toggle'
$('.toggle').hide();
$('.profile_toggle').hide();

// capture clicks on the toggle links
$('a.toggleLink').click(function() {
$('a.profile_toggleLink').click(function() {

// change the link depending on whether the element is shown or hidden
if ($(this).html()==showText) {
$(this).html(hideText);
}
else {
$(this).html(showText);
}
// profile_toggle
if ($(this).html()==profile_showText) {
$(this).html(profile_hideText);
}
else {
$(this).html(profile_showText);
}
// toggle the display
$(this).parent().next('.toggle').toggle('fast');
// profile_toggle
$(this).parent().next('.profile_toggle').profile_toggle('fast');

// return false so any link destination is not followed
return false;
});
});
});

//-->

Right now the script doesn't work with the bottom two variables profile_"ect."
Please help, been working on this for sometime and its probably an easy fix for someone experienced.

Thanks!

Hello guys,
I'm new to this forum and to Javascript. I need to make a very simple website to check whether a ticket number is valid or not. I have created an array with all the codes necessary, but when I try to loop through it, the only thing that works as it should is the first element of the array.

Basically, I want the code to display Correct!, if there is a match between user input and array, or Wrong if otherwise.

Here is my code:
Code:

<!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8">
<title>Untitled Document</title>
<script type="text/javascript">

function validate() {
var list = new Array;
list[0]="zDv5BXAc"; 
list[1]="6YXF3Qwj";
list[2]="k8UKpgwo";
var code= document.getElementById("code");
var name = document.getElementById("name");

for(var i=list.length-1; i>=0; --i) {
	if (code.value == list[i])
	{
		document.all.confirm.innerHTML = "Correct"
	}
	else
		document.all.confirm.innerHTML = "Wrong"
	}
}
</script>

</head>

<body>
<input name="Name" type="text" id="name" size="50">
<input name="Code" type="text" id="code" size="10">
<input name="Check Code" type="submit" value="Verify" onClick="validate()">
<div id="confirm"></div>
</body>

Hello, I very new to this language and I still feel like I'm not grasping it... But, anyways, I'm doing a thing for school and I have to let the user input a string. I need to save the string and turn it into an array. For every word that is less than five letters I put "little" at the beginning of the word and for every word that is more than five letters I put "big" at the end of each word. Then I need to return the new string into output. I think I wrote the code really incorrectly, so any tips/advice would be much appreciated! Also, I don't understand adding user input into a code if that makes sense. The tutorials/lessons I've been looking at all say to put information into an array first and then mess with it. But, what if you don't have information in the array until the user puts it in? And once they enter it, then you mess with what they entered. I can't seem to get how to do that. Thank you for your time

Code:

function texter(newText){
	var oldHTML = document.getElementById('outputPrompt').innerHTML;
	document.getElementById('outputPrompt').innerHTML = newText+"<br />"+oldHTML;
	console.log(newText);
}

function menuTwo(){
	var userInput = document.getElementById('input').value;
	var correctedInputArray = userInput.toLowerCase().split(" ");
	var mainTwo = new Array([""]);
	for(var i=0; i<correctedInputArray.length; i++){
	var thisWord = correctedInputArray[i];
	var lessFive = 5;
	var moreFive = 6;
	var restOfWord;
	if(lessFive<5){
	mainTwo[i]=thisWord+"-little";
	}else if(moreFive>6){
	mainTwo[i]="big-"+thisWord;
	}
	else{
			
			restOfWord = thisWord.substr(1, thisWord.length-1);
		
		}	
	}
	output = mainTwo.join(" ");
	texter(output);
	}
	
</script>
</head>

<body>
<h1>Document</h1>
<input type='text' id='input'	/>
<input type='button' onclick='menuTwo()' value='submit'/>
<p id='outputPrompt'>Please enter 1,2,3 or exit only</b> </p> 
</body>
</html>

Hi everyone,
i am stuck at a problem.
i am trying to craete a redimmensionable array using javascript, is there a way to do this, i know that this can be done in vbscript using redim and preserve commands.

If not then is it possible to variables between javascript and vbscript, or call vbscript function using javascript.

a sample code will be much aprreciated

thanks for your time!

Hi there coding friends,

im stuck again this time on arrays.. Im trying to get my head around it and im sure it's one of those things you do once you know what your doing (to an extent)

now the problem is... i have 2 arrays for a experiment one = flowerheight and the other is flowernumbers.

now the height is set out as 15,16,17,18,19
and numbers 2,1,6,4,2

what the aim is in the first part is to times the height by numbers of the corresponding array ie. 15x2 16x1 17x6 18x4 19x2 to make a 3rd array with them as the totals


then the second part of the program is to calculate the average height i.e total of total of numbers array (2+1+6+4+2) + total of 3rd array(15x2+16x1+17x6+18x4+19x2) then a write to show what the total was..


now all I have of the code is...

Code:

<HTML>
<HEAD>
<TITLE>
Flower Experiment
</TITLE>

<SCRIPT LANGUAGE = "JavaScript">
 /* 
   * Program to calculate average height of flowers.. 
   */

//Experiment results 
var flowerHeights = [15,16,17,18,19];
var flowerNumbers = [2,1,6,4,2];


//Write code to work out and show flowerheightxnumbers.


//Write code to calculate the average height of the flowers (total of flowernumbers + (flowerheight X numbers) and write it out in the browser window.

</SCRIPT>

</HEAD>
<BODY>
</BODY>
</HTML>

now I have no idea how to go about this it's making me loose my mind. Can someone start me off in the right directon and/or explain to me what to do.

Anyhelp much appreciated, I wish I could have done more to the question to make it easier for you lot to help me but my brain is frazzled

Thanks.

I was looking at that old Strawberry Fields problem and I thought I'd see about solving it in JavaScript. What I want is an array of chars so that I can set individual elements in the array of arrays. Strings are apparently immutable and can't directly be changed? Here's my code.

Code:

		var field = new Array();
	var string0 = "..@@@@@..............."
	var string1 = "..@@@@@@........@@@..."
	var string2 = ".....@@@@@......@@@..."
	var string3 = ".......@@@@@@@@@@@@..."
	var string4 = ".........@@@@@........"
	var string5 = ".........@@@@@........"

	for (var i = 0; i < 6; i++) {
		field[i] = new Array();
		field[i] = eval("string" + i + ".slice('')");
	}
	document.write("field's type is " + typeof field + "<br>"); // object? but it should be explicit array
	document.write(typeof field[1])  // string? it should explicitly be an array, then it was filled with array elements
	document.write(typeof field[1][2]); // string - ok, I understand this bit
	document.write(field[1].length);
	document.write("<br>");
	
	for (var i = 0; i < field.length; i++) {
		field[i] = new Array();
		for (var k = 0; k < eval("string" + i + ".length"); k++) {
			field[i][k] = eval("string" + i + ".charAt(" + k + ")");
		}
		document.write("<br>");
	}
	
	document.write("field's type is " + typeof field + "<br>"); // seriously, an object?
	document.write(typeof field[1]) // why is this an object instead of an array?
	document.write(typeof field[1][2]); // string, yeah, I understand this as well
	document.write(field[1].length);
	document.write("<br>");

Also, it looks like I can't overwrite a 1-length string that's in the array of arrays. For instance:
Code:

newField = field;
//for loops
newField[i][k] = 0; // does nothing, newField's elements remain the same.
