Inserting A Variable Into A Variable Name?
Nov 15, 2009
I am having a problem where I want to change a particular variable based on what parameters I send to a js function.
In the code below, dnum is a number 1-6, and I want the global variable d1keep (or d2keep, d3keep etc.) to equal the dvalue.
function KeepDie(dnum, dvalue) {
d+dnum+keep=dvalue;
[code]...
I've tried using single quotes, double quotes, brackets, curly brackets, parentheses, and other punctuation in many locations all over that line of code, but I cannot get it to work.

I'm trying to insert a javascript variable into a hidden input form
field. Here's what it looks like:
<form name="loginForm"
action="scripts/wgate/ziac_login/!?~language=EN">
<input type="hidden" name="pss" value="`G_NEW_PASSWORD.value`">
<input type="hidden" name="usr" value="">
<input type="submit" value="Please Click Here to Continue">
</form>
and then later down the page I try to reassign "usr" like this:
<script>
var allcookies = document.cookie;
var position = allcookies.indexOf("user=");
var start = position + 5;
var end = allcookies.indexOf(";", start);
if (end == -1) end = allcookies.length;
var valueofuser = allcookies.substring(start, end);
valueofuser = unescape (valueofuser);
document.write(valueofuser);
document.loginForm.usr.value = valueofuser;
</script>
I can see it is printing out document.write(valueofuser) correctly, so
I know it is grabbing the user name. But it doesn't seem to want to
insert it into the form on the next line. Any suggestions?

I've been looking around the web and forums for the past few days now. Javascript is not my forte but I am beginning to understand more of it. My issue is perhaps in the method that I have tried to concatenate a variable to my radio buttons.
The scenario:I have about 10 groups of radio buttons , each with 4 options.
radioname1[0]
radioname1[1]
radioname1[2]
radioname1[3]
[code].....
but what I need to know is how to assign a variable to the radioname, so that I can iterate through each radionameVARIABLEHERE[i].value ?
I have been looking and trying to for days. All I really need to know is how to get a variable into the radiobutton name. I know how to use a for loop to get this to iterate through it all but its just the syntax that isn't playing nice.

I am trying to declare a variable inside a function and use it later on in my code... but it just already returns white space... i.e. not variable value. I am setting it within this function:
function show_video1(){
document.getElementById('video1').style.display="block";
var video1Name = "Education World News (Part 1)";
document.getElementById('video2').style.display="none";
document.getElementById('video3').style.display="none";
document.getElementById('video4').style.display="none";
[Code]...
and trying to call it later on with this: <script type="text/javascript">document.write(video1Name)</script> It might be worth noting that each one of my 11 videos will hace a different name.

Ok, so I've built a member search using ajax to change the results each time a filter is changed. It works great, except one minor issue that I'm struggling with...I just can't specify dynamically in the parent file that linkclass$id opens linkclasscontent$id as I don't know of any way to pass that $id variable back over to the parent.

i'm not really sure how to explain this, since I know nothing about javascript, so i'll try and illustrate by the use of php (hope it makes sence)
I have a set of different links, like:
<a href="link.com?page=text1">text 1</a>
<a href="link.com?page=text2">text 2</a>
<a href="link.com?page=text3">text 3</a>
etc, where page is dynamic and can be anything I chose..
Another place in the same document, I echo out what the page variable is, like:
echo "$page";
so when clicking "text 1" the echo will output what i've defined the page to be, in this case "text1" ..
So I want to be able to click the links and change the output of the echo all depending on what i've defined in the link - without refreshing the page!
Is there any easy way to do this?

a.) specify two parameters for the changeYear function: today and holiday.
function changeYear(today)(holiday){
b.) in the first line of the above function, use the getFullYear() date method to extract the 4-digit value from the today variable and store the value in a variable named year.
first line
c.) in the second line; use the setFullYear() date method to set the full year of the holiday date object to the value of the year variable.
second line
d.) in the third line, use a conditional operator on the year variable. The test condition is whether the value of the holiday date object is less than the today date object. If it is, this means that the event has already passed in the current year and the value of the year variable should be increased by 1.
third line
e.) in the fourth line of the function, again set the full year value of the holiday date object to the value of the year variable.

I am simply trying to use a global variable in javascript, but can only access the variable on the second call. I can't find anything that relates to this through my searches. My application is supposed to query the server for XML that tells me which years and months are available to put into combo boxes. I want to store this xml in a global variable to access it later.

I start outside of the external JS file by: reviews.init(); reviews.initialiseContent('comment'); This loads my data and loads + sets the comment tab as default. My problem is that in the external JS file (shown below) the loadTabs variable will not allow me to pass it a variable: contentDiv.onclick = this.initialiseContent; Whenever I pass a variable here it errors, am I setting this up correctly, should I be using prototype for my this. variables? Interested to hear back on if this structure of code is the right way to go about this and also how I can pass a variable in this way :)

I have a programing problem that have been around for ages. I have search on google using several expressions and words and after hours of digging i'm still unable to do it.I would like to get a value from a HTML page hosted remotely with an inconstant value. Then define this value and name as a javascript variable and apply or show in my page.P.S. Is there any way to make a domain lookup in javascript? I mean a user enters a domain and the script converts to an ip and shows to the user. If not thanks, probably it can only be done in the server side...

I want to load an html div in a variable, modify it in another variable; and then change the document injecting the contents.
1. I load the html to be changed in a variable (code)
2. I modify an attribute of <param> using attr() and I put the result in a var (newcode)
3. I change the html in the doc
I've used the debugger, and all steps give the expected results, except of newcode.html(), which is a null string. Why?

I'm trying to create an array of dates two weeks apart from an arbitrary startDate, and I've noticed some odd behavior in my variables. I did a little experiment on my JS console and here's what I got. My inputs are in blue, the output is in black.
Code:
Everything's good so far, but here's where it gets odd. I try to add 14 days to cur.
Code:
Why is it that when I make changes to cur, the same changes are made to startDate?

Basically I have a javascript variable... var caption... I need to get that into php so I can run a mysql_query... I then need to get the result back in to javascript...I can do the last bit... In fact I have it almost working except the first bit... Here's the code...
function showpic (args) {
var argsarray =args.split ("_SPLIT_");
var imgurl =argsarray[0];
var caption =argsarray[1];
[code]....
The end result needs to be this... I need to lookup if the value in var caption is in the jos_jxzine_articles database... Then I need to return the id from the appropriate row as a argument for shadowbox.open...

the following block of code is for demonstrative purposes only:
for (x=0;x<=2;x++) {
game + x = "Game "+x;
}
Okay so looking at that you can probably get the feeling for what I want to do. why I want to do this, as obviously the above code makes no sense and can be done with arrays, but I assure you I have a purpose for doing what I want to do.
The question is, can I put a variable, like x, into a new variable's name? The idea is that the code above generates three new variables:
game0
game1
game2
I've tried using brackets and parentheses, I've tries so many things. I've even tried using the eval() function.
So, again, in short, can I place a variable into another variable's name?
