Index Of An Array Entry
Mar 24, 2006I'm refering to an entry in an array by it's string key, as in
foo["bar"]. Is there a way to get the numeric index of that array
without iterating through the entire array?
What I need to do is find the "next" or "previous" entry in the array,
but the keys are strings, instead of numerical indeces.

Select A Random Entry From An Array?
Aug 30, 2010So, I am attempting to select a random entry from an array, and then make it so that particular entry will not be selected again until every entry has been selected. Basically, I don't want to see any of the same entries, until all of the entries in the array have been selected.
So if this were my array....
keywords =
[
"ppc",
"games",
[Code]....
since meta was selected a second time before everything had been selected once.
I would like to see something more like
meta, advertise, gaming,ppc, welcome, home, games, advertise, ppc, since this did not select any entry multiple times before every entry had been randomly selected.( the second loop started at the second "advertise" in case you didn't catch the differences.
But as you can see from the code that I have posted above, I do not know how to do this. I have seen examples where the entries that were randomly selected, were actually deleted from the array entirely but this is not what I want to do. I just want every entry to be selected once, and then for the process to be restarted.
Take Data From An Array And Apply Each Array Item To An Element
Mar 26, 2010I'm trying to grab values from a set of arrays based on the value returned by my select box.
**Caveat - this is not an area I have any real experience with**
My arrays look like:
Code JavaScript:
I then need to test for each, then associate with one of my fees arrays, then grab each of the values in the array and write those values to elements within my page.
I'm then doing this to evaluate for each degree
Code JavaScript:
I need to first figure out how best to import all of these 60+ arrays and then in each of my conditions pull out each value and write to my page.
There is a unique 1 to 1 relationship between each degree and array so I can't consolidate as the values for each degree differ slightly.

Form Entry To Time Part Of Database Date Entry?
Aug 1, 2005I have a textbox on one of my forms that is used to accept a time from the
user. I need to write this value to a database to trigger an event later on.
What I'd like to know is...
Are there any functions in javascript that can convert different time
formats to a known format (24 hour clock)... 5pm -> 17:00 or 5:00 to 05:00,
etc. ???
Assuming that I get the input into a 24 hour format, how can I create a full
time/date variable with todays date and the users entered time?
Finally, if the entered time is earlier than the current time, how can I
create the above date/time combination using tomorrows date?
Accessing Certain Columns Of An Array
May 3, 2011If I have this array
Code:
testarray = [
["1", "test1", "test11"],
["3", "test3", "test33"],
["5", "test5", "test55"],
["2", "test2", "test22"]
];
How do I access the 2nd column of the 2nd row?
I tried:
Code:
alert(testarray[1][1]);
But it says undefined.
Accessing Array From Function
Jul 9, 2007<script type="text/javascript">
function popsizes(colorcode) {
var BLK=new Array();
BLK = ["2XL","3XL","4XL","5XL","LG","MD","SM","XL","XS"];
elem = document.getElementById("selcolor");
for (i=0; i<elem.options.length; i++){
sizelist = colorcode[i];
document.getElementById("selsize").options[i] = new Option(sizelist);
}}
</script>
In an event, i'm passing in "BLK" as the colorcode param. This is creating my selsize select box with B, L, K, and undefined options until the for loop finishes. ie, its taking the passed in colorcode as a literal string, instead of referencing the array. Anyone have a pointer as to how i can access the arry, instead of the literal string?
Best Way To Find If Item Is In Array?
Aug 31, 2005What's the best (i.e. fastest) way to find out if an array contains a given
value? Other than looping, the only way I know to do it is to use an
associative array/hash instead....
Is there a better/faster way?
I.e if I have a list of names, what's the best way to find out if the aray
contains "jane"?

Extracting Item From An Array
Aug 17, 2011This randomising function is like a coin toss, it gives a numerical result and displays it:
function Ran() {
var c = Math.random();
return (c < 0.5) ? [0, show0()] : 1, show1()];
}
I want to extract the numerical outcome, 0 or 1, from this and from two other similar functions, sum them, and then run more functions based on the possible sums.
What is the syntax for getting to the numbers? something like
var n = Ran().[0] ?

View 2 Replies View RelatedAssigning ID To Item In Array?
Sep 29, 2011I am currently putting together a trivia game and I have stored several items in an array for example the questions, and the answers, points value... etc.
but my dilemma is I have to assign an "id" to the elements in the the array so i can use the function getElementById() to call the information. I do not have a clue how to do this.
*** also the second issue is my array is showing an error as UNDEFINED BUT i have declared it in "var triviaArray"
this is my array:
var triviaArray = new Array [

Javascript Accessing An Array Of Checkboxes
Jan 15, 2006In my HTML, I have several of the following:
<input type='checkbox' name='right[]' id='right[]' value=Ɔ' />
All are the same except the value is set differently for each one. The
reason for the [] is so I can access the checkbox values as an array on
the processing page (when clicking 'Submit');
However, I want my Javascript code to examine these objects first. My
onclick event handler function (below) is called (I get the 'hi there'
popup), but it does nothing afterward (i.e., neither 'checkbox' alert
appears, and the handler, strangely, seems to return 'true').
I suppose my problem is that I am not specifying the checkbox array
properly. I tried several variations, but I've been working on this
problem alone for several hours and am getting nowhere. Code:

Show One Array Item Until It's Time For Next?
Sep 17, 2010here I have array :
Code:
l[1.0]='A';
l[1.4]='B';
l[3.0]='C';
[code]...
And time :
Code:
var time = document.getElementById("time").innerHTML;
But making it
Code:
document.getElementById("k").innerHTML = l[time];
puts false into mine div, time changes alot and is in same format as array names.That function is repeated every 100 microseconds :
Code:
window.setTimeout(myFunction, 100);
Trying to do that in console tells me that doing it like : l[document.getElementById("time").innerHTML] gives me some value while using time variable just undefined, no matter it's same value Next problem I would want my text appear somehow like this when time is 3.0:

JQuery :: Scope Of Accessing Array Object
Feb 14, 2011I'm a little puzzled over the possibility of accessing an array. I've declared the previd id - in the proxy.invoke call which works just fine (we have already implemented an .each loop which also works. My problem is this - after accessing the proxy.invoke function, the previd is populated correctly with push but after the call, we cannot seem to access the previd array to make a join to a string. Here's the basics of the code.
var previd = [];
proxy.invoke("validdateIDCard", p_caregiverid,
function(validaterID) {
var valcard = validateID;
previd.push(valcard);
}, onPageError);
var finalvalue = previd.join("|"); <-- this is where the problem lies - cannot seem to read the variable...
Accessing Values Of Array Type List Box[]
Sep 6, 2007i have a php page in which i have a listbox as below:
<select NAME="scopeid[]" id="scopeid[]" class=sel1 multiple size=4>
<? while ($qrrs=mysql_fetch_assoc($qrrid)) { ?>
<option value="<?=$qrrs['scopeid']?>" <? if($db->isinarray($scopeid,$qrrs['scopeid']) ){ print " selected "; } ?>><?=$qrrs['scopedescription']?></option>
<? } ?>
</select>
<input type="button" name="add" value="Add" class=button onclick="Add()" style="width:40">
how do i pass the values of listbox[] to javascript?
below is my javascript:
function Add() {
Obj=(document.getElementById("scopeid[]"));
alert(Obj.value);
}
alert gives me only the last selected value and not the entire values. i.e if the user has selected 2 ,3 and 4th option, it gives me value of only 4th item instead of all three. how to do it?
