I am developing a website using dreamweaver, and have grinded to a hault!
I have a section of the site whereby an orderform is filled in by a user. There is a link to a colour page, and i would like for the user to be able to click on a colour swatch, and have the form updated with the colour name and reference number. Check it out to see what i mean, www.hexagondraw.com.

this should be done using javascript.

you can put an onclick command on the image and have that image update a piticular field of the order form.

ill get back to you

OK
put the script in the head of the page
put the input of the form in your form (you can change the name of the field, BUT also change it in the script
put the onclick action on the images (change the (1) to whatever you need it to be.
Good Luck


<head>
<script language="JavaScript" type="text/javascript">
<!--
function change (newitem){
document.form1.textfield.value=newitem
};
// -->
</script>
</head>


<form name="form1" method="post" action="">
  <input type="text" name="textfield">
</form>

<img src="bullet.gif" width="25" height="25" onclick="change(1)">

hi rockman

thanks for the reply. Do i put the script into the head of the form page, or the colour page? (sorry, im new to this)
when u say change the 1 to whatever, i take it "change(1)" becomes "change(ral 9010)" etc. What about form.1? does this change to?

From your question, I assumed that you were using only one page.
Ill have to change a couple of things.

BUT
Yes, change 1 to (ral9010) (that i guess will be the color number?)
yes, also you may have to change form1 for the name of your form

I get back to you about the pages.
I now assume that you have TWO windows open? one with the orderform and the other with the colors?

OK
a couple of steps

put this in the head of your ORDERFORM PAGE

<script language="JavaScript" type="text/javascript">
self.name = "orderform"; // names current window as "orderform"
</script>

add target="main" to the links, like this

<img src="bullet.gif" width="25" height="25" onclick="change(1)" target="orderform">

*note, in this senerio, both pages must be open at one time (kind of like a popup, or frames)

OK, got it (FINALLY)


form of the orderform*********************

<input type=button name=choice onClick="window.open('colors.html','popuppage','width=250,height=200,top=100,left=100');" value="Select Color">
<input name="color" type="text" id="color">


colors.html page**********************
<head>
<script language="JavaScript">
function sendcolor(t){

window.opener.document.orderform.color.value = t;
window.close();
}
</script>
</head>


then for each color swatch:
<a href="#" onClick="sendcolor('thiscolor1')"><img src="whatever.gif" height="30" width="30"></a>

Just tested it and it should work

hi rockman,

managed to get the pop up there no problem. However, when i click on the icon for the colour swatch, nothing happens. The pop up stays open, and the form doesn't get filled in.

Does it matter which version of Dreamweaver im using? (Dreamweaver MX) - i just cant crack it. Feels like were so close to!

no, DW version makes no difference.  this is javascript and as long as your browser is Javascript enabled, it should work.

just copy and paste my last code and dont try to change anything yet, see if it works first.

a couple of things to note,

the form on the orderform page must be named 'orderform'  OR change it in script on the colors page
the textfield for the color must be named 'color' OR change that as well

If that doesnt work, do you have an online version I can see?

on this line

<input type=button name=choice onClick="window.open('colors.html','popuppage','width=250,height=200,top=100,left=100');" value="Select Color">

change to

<input type=button name=choice onClick="window.open('colors.html','popuppage','width=250,height=200,top=100,left=100,scroll=yes');" value="Select Color">

This should work.
