Re: Trimming Comma from the beginning of string...

I know this is a JS question.. but i have a string being passed through the
url and it has a comma leading it... IE:

I have this function:

this is running through a for loop to get all the checked boxes in all forms
on the page.

var elete_name_array = new Array();

if ((formele.checked == true) && (id)) {

      delete_name_array[i] = id;

}

//this is a pupup window function i have
new_window(''../popup.php?names='' + delete_name_array);

when i view the url this is whats getting passed...
popup.php?string=,,,,,,,,,bob,mary,sue,bill,mike

even though i told it
if ((formele.checked == true) && (id))

Im not sure why its doing that

I would like to trim this value before it gets sent to the url...(all post
and pre commas)

can someone please tell me how to do this.. i tried googgling it.. not sure
why im not finding what im looking to do.

probably the bes thing is to be sure there is a checked value which that IF
statement should be doing  in eitehr solution..
id still like to know how to trim these types of values that are statically
specified or a string of stripped chars via an array!

tks much guys... I hope i have provided enough info this time :)

It is generally better to use an initialiser:

  var delete_name_array = [];

A simpler and sufficient test is:

  if (formele.checked && id) {

Where is the value of ''id'' set?

Where is the value of i set?  You might want:

      delete_name_array.push(id);

You should be doing something like:

  var n = encodeURIComponent(delete_name_array.join('',''));
  new_window(''../popup.php?names='' + n, ... );

>
> even though i told it

Probably because of the value of i, which I guess is being set as a
counter in the loop so that you create a sparse array, hence the
elisions.

For straight javascript questions, use comp.lang.javascript:

Re: Trimming Comma from the beginning of string...

hey stripe-man,

this should be a more ''prototype way'' to achieve what
you''re after.

encodeURIComponent($$(''.css_class_of_your_checkboxes'').findAll(function(cb){return
cb.checked}).pluck(''id'').join('',''))

how can i properly change this

THIS WORKS=>    formele = eval(document."+ form + id
".delete_names_array" +

As I said, you will get better javascript support at clj - the answer
to your question is on that news group''s FAQ:

<URL: http://www.jibbering.com/faq/#FAQ4_25 >

You should assume that any use of eval is totally unwarranted - the
cases where its use is appropriate are few and far between.

If you are trying to serialise a form''s content, then use one of the
many form serialisation functions that have already been written.
Prototype.js has one, but there are others.   AjaxToolbox has a good
one:

<URL: http://www.ajaxtoolbox.com/request/
documentation.php#serializeForm >

Finally, your form controls should be using names, not ids and you
should be basing your logic on their value, not using the ID as a
pseudo-value.  That way you just serialise the form and send it, most
servers will be (more or less) oblivious to how the request was sent
and will handle standards-compliant requests automatically.

That way, if scripting is not supported or disabled, your form submits
and gets the job done the old way.  If scripting is available, you use
AJAX and provide a bit of convenience for the user.

Re: Trimming Comma from the beginning of string...

THanks for that tip.. that worked.

I am still trying to learn all i can about ajax and prototype  its a lot to
soak up.
This page im working on is tricky.

It can have hundreds of records on it with each record having about 4 forms
that can be used with it.
the [] was necessary so that a ''select all'' feature would work
(i have been
using it with ONE form and mulitple rows
and never had any problems..

But I had to get a bit creative for it to work with mulitple forms but the
same field name.
I''m sure there is a better way to do it.. I will have to revisit it
later.

I did try to find something relating to the [] and grabbing those fields..
But didnt find much.  I think I have to how to search better.

Thanks for your time and trouble Rob.....

Re: Trimming Comma from the beginning of string...

Regarding your example, the var definition "elete_name_array"
doesn''t match "delete_name_array" used in the loop, but
perhaps you''re declaring it elsewhere.
   
  Checkboxes are only passed when ticked. However, you might want to add another
condition to confirm the input type is indeed a checkbox.
