Javascript Dynamic Drop Down Menu

vaaliban · #1 03-01-2002, 02:45 PM

Hai

since i am new to javascript pls, pls help me to understand if anyone can.

the main concern for me is to pass the value of the second drop down menu ,that gets dynamically generated to the cgi server, when i select the option in the first drop down menu.
I have listed the code below.

say for example,

lets consider the first line of the "new array" which has the value
new Array("Saku Koivu", 39482304), (this is the second drop down menu that gets dynamically generated when I select the option in the first drop down menu)

now if the second drop down that shows to the user is "saku koivu", and the value that I want to pass to the cgi server for this option is "author", where do I place this value and how does this gets passed to the cgi server.

and also I have one more question

if I for saku koivu option, if i have to pass a value as "author;A"
(notice the semicolon in between the author and the A, where do I place the value in the code and how does it gets passed.

kindly help me.
thank you
Bala.

Hi vaaliban

As far as I can see, you are passing a numeric value (array item number 1) as the value for each option. If I understand you correctly, you want to pass ( in the instance of "saku koivu" the value of "author", so why not change it in the Array or am I missing the point?

hai,

did u mean to change the value of the option in the array like this

instead of,

the "new array" which has the value
new Array("Saku Koivu", 39482304),

you want me to change

the "new array" which has the value
new Array("Saku Koivu", author),

if this is what u meant

then I did that already and the value is not passing thro,

do u know what more I can do to pass the value of that option.

Hi vaaliban

Did you have:
new Array("Saku Koivu", author),
or
new Array("Saku Koivu", "author"),

vaaliban · #5 03-03-2002, 02:47 PM

hai

i had
new Array("Saku Koivu", author),

why? should it be
new Array("Saku Koivu", "author"),

and also
if i want to pass the value like this author;56 (notice the semicolon in between the author and the 56, where 56 is the age of teh author)

should I do

new Array("Saku Koivu", author;56),

or

new Array("Saku Koivu", "author;56"),

thank you

Hi vaaliban

It should be in quotes to make it a string value. Otherwise you are saying that author is an object or variable and it will be looking for the value of that to pass. So:

Code:

new Array("Saku Koivu", "author;56")
