I'm writing a debugging script and I'm passing a function an object to iterate through:
myObject = {a:1,b:2}
debug(myObject);
I'm wondering if there is any way to get the variable's name as a string("myObject"), so something like a .name property:
function debug(obj) {
alert(obj.name); // would alert "myObject"
}
Is there any way to do this?
I have a string that I want to de-construct into several variables. I know I can use Indexof and Slice to do this but was wondering if there is something similar to Indexof that will give me every position of the separator. I know that the separator will always occur a set number of times in the string.

I have a PHP page generating a list of items. I've made it so that
each one has a radiobutton with a unique value. You can click on the
radiobutton and it will change the value of a text field to the value
of the radiobutton--all that works fine!
Now, I need to also have it populate a textfield with the value of a
textfield in the row that's selected.
I can make unique field names, no problem. I think my problem is
getting the javascript written so that it recognizes the variable.
Well, see below. As it's written below, the textfield "itemqty" always
has the value "NaN" (wherever THAT comes from) no matter which
radiobutton I select.
I'm working on a rather complex booking system for building European
trips, in a combination of SQL/VBScript/Javascript. There are tons of
query string variables that get passed back and forth between the
pages, and in almost every case, I can set 'em up fine, provided the
variables are in the link.
The page the *holds* the booking information, though, is problematic.
An example trip might include two European cities or towns with a week
in each in an apartment or cottage that the user selects from a dozen
or properties for each region.
All the information is on one page (all the dozen or so properties for
each weeks, available dates for the trip and for each , max occupancy
per property, pricing per property and per number of passengers,
etc...everything necessary to actually book the trip). If the user
changes party size or chooses a date, properties are hidden or shown
depending on max occupancy and/or availability.
So, a user sets their date and party size (or maybe just the party
size, or maybe has just cleared everything out to start over...) then
wants to view available properties so they can find one they like. The
current pax/date/etc. information is not in the query variables,
because the link was built at runtime.
If I build the link in an onclick event, it breaks if someone right
clicks to open a new page or tab.
I hate sites that disable right click menu. I hate sites where, when
you open a new page with a right click, it generates a javascript
error if the URL is created with an onclick event. I hate that using
an onclick to bring up the page means whatever is showing in the
status bar bears no resemblance to the page that is brought up when
you click on the link.
My client isn't worried about the non-javascript people for this use;
those people are referred to a free spiffy catalog, which frankly, is
how most of this client's customers book their trip anyway. I just
want to be able to carry the variables in such a way as to not break
the site if someone right clicks.
Anybody have any suggestions? Is it hopeless?
I feel like I have been repeating this code lately, so I cleaned it up and am gonna show it here. This function returns an array (with hash names) containing all the get variables.
function parseGetVars() {
var getVars = new Array();
var qString = unescape(top.location.search.substring(1));
var pairs = qString.split(/&/);
for (var i in pairs) {
var nameVal = pairs[i].split(/=/);
getVars[nameVal[0]] = nameVal[1];
}
return getVars;
}A simple page to test this looks like<html>
<head>
<title>Test</title>
<script>
function parseGetVars() {
var getVars = new Array();
var qString = unescape(top.location.search.substring(1));
var pairs = qString.split(/&/);
for (var i in pairs) {
var nameVal = pairs[i].split(/=/);
getVars[nameVal[0]] = nameVal[1];
}
return getVars;
}
</script>
</head>
<body>
<script>
var g = parseGetVars();
for (var i in g)
document.writeln(i+'='+g[i]+'<br>');
</script>

What is stopping my code from displaying the time, date, and greeting from my stored variables?[code]...
I also tried placing paragraph tags, "", and '' ,respectively, inside the parenthesis as well as using '+variable+' instead of " . variable . "
The word "blah" was used to make sure the marquee tag was supported by browsers I have used to test this. So far I have only run into trouble with my document.write(stuff) not being displayed.
I want to pass some variables from one page to the other. Question is, why the following won't work?

The value of sq1 will remain undefined. It is updating actually, but why it stays the same in query string?

i'm trying to create some javascript string variables using php. i'm running into a problem because some of the variables span multiple lines and this is causing a problem. here is a sample of what i'm trying to do:
var thetext1=new Array()
thetext1[0]="info for #1 goes here"
thetext1[1]="info for #2 goes here"
thetext1[2]="info for #3 goes here"
etc.... the array values are output from a mysql db using php and used for a script i have on my page.
the problem is some of my strings span multiple lines and end up making it look like:
thetext1[36]= "this is an example
of how some stuff spans
multiple lines"
Using the javascript console in firefox i see the problem is: "Error: unterminated string literal." I believe it is because the string I am trying to input is spanning multiple lines. any idea on how to fix this?
i'm using php/mysql to create these javascript variables so i have access to their functions. i tried doing this:
str_replace( "
", '', $row['text']);
to replace the newlines with nothing but they're still there.
any ideas on how to get around this?

I have a program written in Javascript and fully functioning which takes a user-selected directory name and then displays all the photos in that directory in a certain format.
I am now wanting to expand the program to allow users to optionally enter their own strings and the program will use all the photos from www.flickr.com which use that string as a tag.
I have a PHP interface to flickr (called PHPflickr) which collects all the relevant photo urls. I now need to get these images back into my Javascript so I can process them using the existing functions (rather than rewrite all my functions in PHP code and have two sets of functions in the program). I found on another thread a means to do this for a date variable:
var jsArray = new Array(
<?php
$length = count($monthDataArray);
for ($i = 0; $i < $length; $i++)
{
echo '"' . addslashes($monthDataArray[$i]) . '"' . (($i < $length - 1) ? ',' : '') . "
";
}
?>
but being completely new to PHP I'm not sure what "addslashes" might be or what formatting will be necessary if I am starting with an array of urls. Code:
I need help with substring or trim function in javascript. Find below my code. Selection holds the value Select State, and length of the string is 14. I need to equate the Selection value to string "Select State" and execute alert message.

I tried this:

How to check if some char in textbox contains one of the ones in string "allowedChars"
I am currently trying to build a new function in javascript that is supposed to handle a string of text. The idea is that it should find the lowercase letters and uppercase letters in a string and then swap them.
Meaning all lowercase letter becomes uppercase letter and vice versa.
So i am just asking if someone could point me in the right direction or give some tips. I've currently been reading about the toUpperCase(); and toLowerCase(); functions and i am fairly confident i know how to use them for switching, however i still need a way to find the lower , upper character in the string so i later can switch them.
Here is my code:
<script type="text/javascript">

</script>
My problem is im trying to use string.replace that is not case sensitive and replace every string found. I could use regular expression with it but my stringToBeFound is a dynamic variable im getting it from my database
How can i remove a string from an existing string in javascript. I have a textbox in a form and want to make sure that when the user clicks a button that certain words are moved, like all instances of "hello" should be taken out of the text the user typed in the textbox.
