Getting Values From Select Array?
Oct 19, 2009
I have a select array like this ..
Code:
<SELECT NAME="state[]" MULTIPLE size="10" onchange="content();">
<OPTION VALUE="abc">abc</OPTION>
<OPTION VALUE="zyxc">zyxc</OPTION>
[code]....
So I created a javascript to get all the selected values in one variable ... But whtever I try the values don't come .. I tried alerting at different places and wht I see is tht it don't even go into the for loop ...
Code:
<SCRIPT>
function content() {
var retval = new Array();
for(i = 0; i < document.form100.state.length; i++)
[Code]...

This one is throwing me off! Either I am making a stupid mistake or I'm doing it totally wrong I have an array, and I am trying to select unique values from it and assign it to another array. Here is the code:
Code:
var flag;
for (i=0;i<=pdfs.length-1;i++)
{
flag = 1;
for (j=0;j<=pdfs2.length-1;j++)
[Code]...
The problem is that the if (pdfs2[j] == pdfs[i]) statement ends up never being true. There are URL's to pdf files in the array. On the other side, if there is a much easier way to select unique values from an array, please feel free to point it out.

I am working on a class registration system that requires students to register for a main class (101, 102 or 103). The student is supposed to select one main course as well as provide a second choice in case the first is not available. I have two dropdown select fields to capture data
1) Choice -1: 101 / 102 / 103 ( Student needs to select one - Reading the classID from classes table)
2) Choice -2: 101 / 102 / 103 ( If student selects 101 in Choice-1 then the only classes available under Choice-2 should be 102 or 103).
How can I accomplish the above? Further to this there are two fields on the form where I would like to auto populate based on what they have selected in Choice-1 and Choice-2.
For Example:
If a parent selects choice1: 101 the child Choice1 field should autopopulate with 100.
If a parent selects Choice2: 201 the child Choice2 field should autopopulate with 200

I need to pass an array of client side events to the next page. Here my user would perform a few events which would be stored in a javascript array, upon completion a submit button would be used to post all that data to the next page.
An example of such a process is listed below, returning that array back to php so that I can post it to the next page. I am trying to populate different entries made into textbox into the array arr. And when I would click the submit button, I want to post that array.
<html>
<head>
<script type='text/javascript'>
function retText(form)
[Code]....
I want to return that arr back and on post I want to send that array to the next page.

I have an array similar to this:
Code:
0 -> 0
1 -> 5
2 -> 9
3 -> 2
[Code].....
There is no clear logic and that does not matter. I need to decrease the values of those by one where the value is higher than x. How would I do this?
For instance, if x = 5, then that array becomes
Code:
0 -> 0
1 -> 5
2 -> 8
[Code]....
All values higher than 5 were decreased by one.

var IdContainer = new Array(); for(i=0; i < SEARCHNO; ++i) { var search_ID = xmlDoc.getElementsByTagName("searchID")[i]; var SEARCHID = search_ID.firstChild.nodeValue; if(SEARCHID !== IDCONTAINER) { code to add the SEARCHID to the IDCONTAINER array here
Now what i want it to do is every time the for loop runs the if statement checks whether the SEARCHID variable is not equal to the values in the IDCONTAINER array....if this is the case then the code after the if is run and the value in the SEARCHID variable is added to the IDCONTAINER array.
Problem is i dont know how to structure the if statement to check all the values in the array against the SEARCHID and then i dont know how to update the array afetr the if with the new SEARCHID.

Let's say i have two arrays:
var array1 = ["1","2","3"];
var finalArray = [];
and I want to dump the values of array1 into finalArray several times to end up with the value of finalArray being:
"1","2","3","1","2","3","1","2","3"
What would be the easiest way to dump the values into the other without making it multidimensional?

Can a javascript array value be used in an onclick event?
I haven't been successful in getting it to work so I'm wondering if it
even can be done.
onclick="calculate('some array value');
I've tried:
onclick="calculate('<script
type="text/javascript">document.write(points[0]);</script>');
There's conflict with the quotes, but beyond that, I'm unclear if this
is even a viable option...anyone?

'm having a very hard time making this work and be happy in both IE and Firefox. Basically, I'm setting a timeout to get an array of the form values if not present, or compare against if they are present, and if any change in values, submit the form to auto-save it.
below is my coding, basically I am using document.forms[thisformname].elements - but that gives me a lot of things that are NOT form fields and I just need to read input:text, input:checkboxk, input:radio, textarea, and select elements - nothing more. I'm open to any suggestions and some of you smart guys could probably write this in half the lines I did.
Code:
//auto-save coding
var autosaveTimelapse=0;
var autosaveTimeout=3; //every n seconds
