Javascript/VBscript hidden values & page redirect

[Sridhar_Rao]

I have a html form, where user makes a choice using drop-down menu. There are other elements in the form too. I use a vbscript to send the element values to my email.

<form name="test" method="post" action="cdosys.asp">
<input name="_recipients" type="hidden" value="mymail@myurl.com" />
<input name="_requiredFields" type="hidden"  value="name,email,country" />
<input name="_replyToField" type="hidden" value="email" />
<input name="_redirect" type="hidden" value="" />

This works when a predetermined value is entered. for eg. value="this.htm"
How do I place the value of input name (in red colour), depending on what the user chooses? What is the code?

<select id="ddbox" onchange="document.getElementById('redirect').value=this.value">
   <option value="location1.html">Location 1</option>
   <option value="location2.html">Location 2</option>
   <option value="location3.html">Location 3</option>
</select>

Thanks, but what should go into the value=""?

<input name="_redirect" type="hidden" value="" />

[victor_rambo]

^That will be dynamically decided, when the user makes a selection from the drop down.
Isn't that how you wanted it?

[Sridhar_Rao]

Yes, but you did not get my point. The code

onchange="document.getElementById('redirect').value=this.value"

places the value into the hidden element redirect.
But, the question is what should I mention in this line?

<input name="_redirect" type="hidden" value="" />

The code is not working, as the value is not specified here (value="")

[victor_rambo]

^That is because you have not declared the ID attribute in that element. Do it and it shall work.

[Sridhar_Rao]

I tried that too. Here is the code

<select size="1" name="choice" id="choice" onchange="document.getElementById('redirect').value=this.value">

what about this one? Should it be

<input name="_redirect" type="hidden"  />
or
<input name="_redirect" type="hidden"  value=""/>

Anyway, it does not work.

I tried another workaround.

<select size="1" name="choice" id="choice" onchange="goto()">
function goto(){
x1 = document.test.choice.selectedIndex; 
x2 = document.test.choice.options[x1].value;
document.getElementById('_redirect').value=x3;
}

This doesn't work too.

I guess, I am making a mistake here. You are probably referring to hidden element's id. I now corrected it to

<input name="_redirect" type="hidden" id="hid" />

and made correction here:

<select size="1" name="choice" id="choice" onchange="document.getElementById('hid').value=this.value">

yet, it doesn't work.

[victor_rambo]

^how are you confirming if it works or not?

[Sridhar_Rao]

The page is not getting redirected at all. Anything wrong with the code?

<input name="_redirect" type="hidden" id="hid" value="" />
<select size="1" name="choice" id="choice" onchange="goto()">
function goto(){
x1 = document.test.choice.selectedIndex; 
x2 = document.test.choice.options[x1].value;
document.getElementById('hid').value=x3;
}

[victor_rambo]

^Thats because nowhere you have used the code for redirection. You just said that you want the redirection value to be put in the hidden field.

window.location=document.getElementById('redirect').value;

[Sridhar_Rao]

<input name="_redirect" type="hidden" id="hid" value="" />

The VBScript handles this. I am sending all the parameters to cdosys.asp, which does all the redirection business. My interest is to get a value to this element.

If I enter anything for this value="abcd.htm", it works fine. I only have to give that value dynamically based on user selection.

^Your id="hid" should be id="redirect" for Rohans code to work.

[Sridhar_Rao]

That is not an issue, I have referred the same id in both places. I have used hid in the element as well as in the script.

Well, I got it working now. I had made a simple, but stupid mistake. I was passing the value by value and then trying to catch it by reference.

[victor_rambo]

Oh, I forgot to tell you, I am posting in javascript, make sure to use its equivalent in VBscript, else it obviously wont work!

[Sridhar_Rao]

No, your post was the right one. I messed it up due to my stupidity. Read above and you will know. All I had to in the javascript function was to add this line:

document.getElementById('hid').value=document.test.choice.value;

And it works. Thanks Rohan
