Dropdown Boxes

Recommended Posts

Alright,

I am making a bracket system, and I want it to add the selection to the next drop down box, but I need to be able to process the picks as a php variable, but I can do that part.

 

How can I do this:

Round 1

Team A

Team B *User selected*

 

Round 2

Team B *User selected*

Team C

 

Round 3

Team B

Team D *user selected

 

and so on..

 

What is this called? How can I do it?

Here is a basic demo; it's got an error (which there is a odd number of select menus) which I am still working on, but it does work. If you will give me a little bit; I will figure out the error and correct it.

 

<select>
<option></option>
<option>One</option>
<option>Two</option>
</select>

<select>
<option></option>
<option>One</option>
<option>Two</option>
</select>

<select>
<option></option>
<option>One</option>
<option>Two</option>
</select>

<select>
<option></option>
<option>One</option>
<option>Two</option>
</select>

<select>
<option></option>
<option>One</option>
<option>Two</option>
</select>

<select>
<option></option>
<option>One</option>
<option>Two</option>
</select>


<script language="javascript">

var max = document.getElementsByTagName('option').length;

for(i=0;i<max;i++)
{
if (i%2) {
i=i+2;
document.getElementsByTagName('option')[i].selected = true;
}
else {
i=i+1;
document.getElementsByTagName('option')[i].selected = true;
}
}

</script>

Well sorta

 

I want 2 options in one list box.

 

1 option is pre-made, and the other option is made from the selection in the previous box

 

Example:

 

Box 1:

Option 1

Option 2 (user selected this option, add it to the next list)

 

Box 2:

Option 2

Option 3 (user selected this option, add it to the next list)

 

Box 3:

Option 3 (user selected this option, add it to the next list)

Option 4

 

Box 4:

Option 3 (user selected this option, add it to the next list)

Option 5

 

and so on..

 

I am really not sure how to go about this.

This may help you see how to add options to a select menu:

 

http://javascript.internet.com/forms/adding-options.html

 

If not; Google something like "adding select menu options with javascript"; that should return you several examples of adding options to a select menu.

 

You also may want to Google "JavaScript Chained Select Menus".

 

Hope This Helps ;)
