[SOLVED] Re: form values

[mgs019]

I started a thread on this before but it got a little side tracked.

 

I have a form where I have a select element with numbered values which relate to diamond colours and clarities. So 1=D, 2=E etc. I also have sliders from the Yahoo UI library which work great. I want to have the value displayed but not as a select. I tried disabled="yes" and it stopped passing the variable through.

 

It seems to work for alert but not document.write!?!?!?

 

My backup plan was to use a readonly textbox with a white border so it would not show up and use javascript to process the variables so something like

 

 

var colname
var colnum = document.forms.diamond.colour.value;
if(colnum=1) colname=D
...

 

in the head as a function, then put an onchange in the inputs.

 

any chance of a bit of help in the formatting for the function, particularly the if or maybe switch part?

 

Thanks alot,

Disabled will prevent that input from being submitted.

 

If you can alert it, you can write it out...

thats what I thought but it did not work. Unless there is something really silly I am missing in the syntax. i had:

 

var x=document.forms.diamond.colour.value
document.write(x)

 

but nothing. If i put quotes around the 'x' it wrote x!

 

I am thinking of going to plan B with this so I thought if I used text fields with a transparent border then I need to translate from the id to the colour/clarity and maybe a description. I thought something like:

 

var coldesc
var colnum=document.forms.diamond.colour.value
switch(colnum)
case 1
document.forms.diamond.colourtext.value="D - Pure white..."
case 2...

 

then an onload in the body tag.

 

Will this work and how should the syntax be for the head script? I am ok with php but I am a bit of a JS noobie.

 

Thanks,

I'm still quite confused... seems like you're not pulling the right value, if x is null/undefined.

For interest I still could not get it t owork properly so used an Iframe with a script to change teh src dependant on the form values. That worked well.
