Storing Array Elements	View Content

Hey All,

I have completed most of a homework assignment that I am working on. I am able to .push desired elements into an array:

Code:

//Insert variable into the Array
function insertElem(){
	//Insert and sort first array, but not second array
	if(nameInput.value != ""){
		studName2.push(nameInput2.value);
	}
	else{
		alert("Value to be inserted cannot be Null");
	}
	
	//Refresh display area
	clearAndShow2();
}

What I would like to do is be able to store and display the created array "permanently" until I decide to remove the elements. My current method to hold the elements, until the page is refreshed, is:

Code:

//Refresh second array
function clearAndShow2(){
	nameInput2.value = "";
	messageBox2.innerHTML = "";
	messageBox2.innerHTML += "Groups: " + "<br />" + studName2.join("<br />") + "<br />";
}

I appreciate the assistance.

Storing Array Values

Hi all

I am trying to create a code which stores information about songs
The information to be stored are :
song ID
song name
song artist
song URL

So far what I've done is create an empty array with four properties
The code asks the user to enter information and then displays them
However i'm having difficulty figuring out how to insert all the information entered in the array. For example if information about 3 songs were entered, how can I insert all of them in the array I created.

After storing the information, I want to be able to search for songs by their ID. When I wrote the function to do this, if lets say I entered two songs one with S1 as ID and one with S2 as ID, I type S1 in the search box, but it doesn't return anything. However if I enter S2, it returns the information of the track with this ID, which makes me think that entering information for a second song overwrites the first one

This is my code so far:

<html>
<body>

<h1>Tracks and Artists</h1>

<script type="text/javascript">

function request(tracks)
{

for (var i=0;i<2;i++)
{
tracks.trackID = prompt("Enter track ID")
tracks.trackName = prompt("Enter track name")
tracks.trackArtist = prompt("Enter artist name")
tracks.trackURL = prompt("Enter track URL")
alert(display(tracks))
}
}

function insert()
{

function display(tracks)
{
return "Track ID: " + tracks.trackID + "\nTrack name: " + tracks.trackName + "\nTrack artist: " + tracks.trackArtist
+ "\nTrack URL: " + tracks.trackURL
}

var tracks = [{trackID: "", trackName:"", trackArtist:"", trackURL:"" }]

request(tracks)

</script>

</body>
</html>

I tried the following code based on a post I saw somewhere else about summing all the elements of an array together. When I tried it though I couldn't seem to get it working. Can someone please point out what I did wrong or tell me a different way to sum array elements together? Thanks.
Code:

<script type="text/javascript">

Array.prototype.sum = function() {
for (var i = 0, L = this.length, sum = 0; i < L; sum += this[i++]);
return sum;
}

var myArray=[1,2,3,4,5];

document.write(myArray.prototype.sum);

Set Value Of Array Of Form Elements

Hi Folks - I have a form that has an array of input values:

<input type="text" name=txtValue[] />
<input type="text" name=txtValue[] />

I do this so I can loop through the values in php... now...that's the easy part... the hard part comes to this:

next to each of those boxes is a search button that allows the user to open up a popup window that they can search for an item, and select the item. Once they select the item it should populate that particular input box with the selected item. I can easily do this with a uniquely named input box, but can't seem to figure out how to do it with an array of input boxes... any idea?

Checking Array Elements

Hey guys. I need a little help with checking elements in my array. I created an array of size 50 and initialized all elements to 1. What i want to do is if the user types in the number "1" into the prompt box, i want it to check the first 15 elements and increase only one of the elements by 1, and if the element has already been increased by 1 then i want it to check the next element and see if its been increased, if the element has been increased then it needs to move on to the next one and check that. If the element is 1, then it can be increased by "1", if the element is 2 then i need it to check the next element. If all elements within the first 15 have increased by 1, it should just alert the user that all slots have been assigned. Is there a way to do this? Thanks for your time

Using Form Elements In Array

Similar Tutorials

Hi,

I'm pulling my hair out to create a simple function!

I am creating an array based on form elements. I then am trying to create an IF (and nested IF) statement to check if the fields are empty and then with the nested IF statement use certain fields to create mathematical functions.

So far I have this:

function QuantityMWh(form) {

var formchk = document.forms[0]
for (i = 0; i < formchk.elements.length; i++) {
if (formchk.elements[1].value == "" && formchk.elements[2].value == "") {
alert("Please fill out all fields.")
break
}
}

}

It's only checking the first field and not the second, and vice versa. i.e. if only one field has text then it passes.

What am I doing wrong?

Thanks.

Prefill All Array Elements With Data

Hi All,

Simple newbie question here - I want to initialize an array with "myString.length" elements, and I want every element to be prepopulated with "*" instead of blank. Is there any way of doing this? Code:

 

var myString = '123456';

var trialVar = new Array[myString.length]
	
document.write('TEST ' + '<BR><BR>' + trialVar);

(I want every element of trialVar to be "*", I cant just manually add them as myString.length will vary)

Any help would be mega appreciated - thank you

Hi Guys

I am new to javascript programming and I am trying to get elements from one array to another, here is an example of what I am trying to do;

Code:

oneArray[0] = anotherArray[10];

Essentially, moving the data in index 10 of anotherArray to the index 0 of oneArray. I have tried using a variable as a place holder such as;

Code:

placeHolder = anotherArray[10];
oneArray[0] = placeHolder;

I know i'm doing something idiotic somewhere along the line, I just can't figure out what I need to do.

Javascript Array Within Form Checkbox Elements

Guys,

For some reason my script only works when I have at lease two checkboxes.

To simulate the problem just run it once with two html input checkbox elements
-> check one checkbox and press submit -> it works
-> Now remove one input checkbox field and check the remaining checkbox & submit -> Bamm doesn't work...

What am I doing wrong ?

Code:

            <script> 
            function Check(chk) 
            {

Problem Comparing Screenx,y To Array Elements

I'm writing a simple Chess Record keeping app (still ), and i'm having a problem with the Screen.X and Screen.Y variables to compare with the coordinate variables stored in an Array.
The project is a little large, so here's the live version (on my website). Though it will only work if you run it from your local disk.

http://daomingjin.googlepages.com/ScoreMate.html

the zip archive of this is he

http://daomingjin.googlepages.com/ScoreMatev1.zip

the main JavaScript function file is he

http://daomingjin.googlepages.com/Core.js

the particular function in question is this:

Code:

var PieceThere = isPieceHere(ClosestX, ClosestY);


function isPieceHere(x, y)
{
 // Test to see if there is an Element at  point  x,y
 for (var i = 0; i < 32; i++)
     {
	  if (PieceLocationXcoord[i] == x)
	     {
	      if(PieceLocationYcoord[i] == y)
		     {
			  // There is a piece there
			  var Result = "True";
			 }
		 }
	 }
return Result;
}

i have placed alert() boxes in many places in the code above, and i can tell the following:
the function is being activated the coordinates of x and y are able to be accessed inside the function the arrays called PieceLocationYcoord and PieceLocationXcoord both have the values in them that are returned by the ClosestX and ClosestY function
however, every time , the function continues to return "Undefined". I have even tried manually setting var Result = "True" inside the last if-then block, and still returns undefined.
i have also tried using the alert box inside this function (before the variable return Result; is called) and still get undefined as the message from the alert box.

i would like to change certain style elements of the array each time the button is clicked. I have 5 color sets i would like use for the page, so i would like the button to trigger the color change in a loop, ie when the last color group is reached, the next click returns to the original color set and it continues again.

This is a demo page, not for actually publication. I am trying to teach myself javascript and this is an idea that came to me.

The things i want to change are the background color of two div's and the top row of a table. My style sheet is seperate, and I will also do the same for the javascript once I can get it to work properly.

Thank you in advance for any help.

Adding Js To Old Html: Referencing Array Elements

View Content

Years ago I created HTML that employs checkboxes and textboxes. I am now writing JS with the intention of adding flexibility and limiting redundancy. I am not sure I truly understand how to correctly interact the two though. For example, one of my scripts have arrays that contain the names of the checkboxes and textboxes, with a 'for' loop to document.write() them to references within the HTML code. This does not seem to be working for me though. Here is what I have thus far (in short):

Code:

<script language="javascript"> 
var teamNames = new Array(3);
 
teamNames[0]="South Africa";
teamNames[1]="Mexico";
teamNames[2]="Uruguay";

for (i=0; i<=31; i++) {
document.write("<p>" + teamNames[i] + "<\/p>");
}
</script>
</head>
<body>
<tr><td>Jun 11</td><td><input type="checkbox" 
name="teamNames[0]" value="teamAbbr[0]"></td>
</body>

I've left out a lot of the code (to include the teamAbbr array, but you get the points. I've tried moving the JS within the HTML body and playing with the reference syntax, but nothing so far. Any help would be great!

Comparing Elements In An Array To Letters In A String

Hi all,

Forgive my ignorance, I'm quite new to Javascript...

I'm looking to do two things: the first is to move elements of an array to the next index using a function. I have managed to do this like so:

Code:

var letters = ['h','i','j','k'];
function moveElements(anArray){

var newArray = anArray;
newArray.unshift(newArray[newArray.length-1]);
newArray.pop();
}
moveElements(letters);

(this may or not be great, but it seemed to work) ... but I want the original array to reset to its original state if the function is called again (thus producing the same answer as opposed to shifting the elements again).

Secondly, and this is the bit I'm really struggling with: I want to compare each letter of a string to elements within an array and display the indices. For instance:

Code:

var myArray = ['a', 'b', 'c', 'd', 'e', 'f'];
var text = 'dead';

Hence I want the result '3,4,0,3'.

I know the answer will use for and if statements but I can't wrap my head around it at all. Help would be appreciated, thank you.

How To For-loop Php Array ($_post) Elements Correctly In Js

I wrote js functions to reset a php form (multiple questions). The below works:

Code:

function resetForm(){
  	   resetGroup(document.forms[0].answer1);
  	   resetGroup(document.forms[0].answer2);
	}

Answer1 and answer2 are the elements of $_POST array. (<input name="answer1"> in php). In this example, I tried with only two questions, but I have up to 35 questions in one form. Instead of writing the above resetGroup() 35 times, I want to for-loop it. I tried

Code:

function resetForm(){
	   for (var i=1; i<3; i++){
  	   resetGroup(document.forms[0]."answer"+i);
	}

That didn't work. Could someone help me to make the loop work? Or would someone have better or simpler idea? Thanks.

Storing Variables Serverside?

Hey guys,
I just recently started getting into JavaScript (2 days ago) after seeing how limited HTML and CSS by itself is, and I created a game where you have a certain amount of time to click as much as you can.

The game works fine but the problem is with my leaderboard. I want to be able to store the high scores and names so that everybody see's the same thing. I know cookies save data but is that only clientside? All I need to do is save 6 variables so that the leaderboard is always updated. Any help would be appreciated. Thanks.
