I’ve read ‘How to get dynamically created inputs from html form back to,  
Posted by David J. (Guest) on 03.06.2006 04:03’ but it doesn’t seem  
to work for me.

I’m using client-side javascript to add input tags to a webpage, but  
when I submit the page, there are no parameters created for the input  
fields, when it is entering the controller???

The code in the .js file:

function addBmw(){  
cnt = $(‘bmws’).select(‘div[id^=bmw]’).size();  
bmw = $F(‘sel\_bmw’).split(’|’);  
bmw\_line = ‘

’;  
bmw\_line += ’&nbsp; ![delete](https://test.ruby-forum.com/images/delete-icon.jpg)';  
bmw\_line += ‘’;  
bmw\_line += ’&nbsp;’ +  
bmw[1] + ‘’;  
bmw\_line += ‘
’;  
Element.insert(‘bmws’, {bottom: bmw\_line});  
}  
function delBmw(bmw\_id){  
Element.remove(‘bmw’ + bmw\_id)  
}

This works fine on the page, but no parameters received in the  
controller ……  
Someone knows an answer? (or is it just working as designed?)

TIA, Adrie
