Varable name & form 1

[Palmke]

Hi all,

I made a function like this :

function save_state(id,field)
{...
//I do some stuff and then this line
myform.field.value=1;
...}

if I make it run, the system doesn't save anything in value of field, I looked everywhere how to write field since is a variable, when you usually use +field+ if like you have to print it but nothing worked.

May anybody help me please?

Where is "myform" defined? If "myform" is the form name, and "field" is a string containing the field name, then use this instead:

document.forms['myform'][field].value = 1;

Shortcutting around DOM methods only short-changes yourself in the long run!

Hope this helps,
Dan

Real thanks! it worked

Now I have two more problems :

1) I have to use the function that I wrote to save something under the column called "field" in that form,
in the same form there's another column which I may call it "user number" that it is not autoincrement but it's the key field and every row has a different number in it.
Now, by calling the function again and again it always writes on the same row, but I need to make it write on the line of the "user" that is actually being referred by that form! I really don't have a clue how to do that.
Today it's my 'first day' of Javascript ...

2) I have to use event handlers for some kind of buttons,
I also have to make it react when you click on + or - buttons of a counter.. i tried onclick and onchange but both of them reacts when the text in it is clicked...
Any help?

Best regards,
Palmke
