Form controls manipulation

[chuxs]

hi, pls i need help. i have an html page containing some Form controls but am also generating and naming some controls e.g Checkbox and Textbox dynamically using a server side script, the naming of the controls(Form) is base on the fields name from my table in my database, now there's my problem. How do i check if a control generated dynamically e.g Checkbox is checked or not by the user using javascript.

...
if(document.forms['formname'].elements['checkboxname'].checked){
...
}

checked is a form's element checkbox attribute
values are booloean true/false
the default (obj.checked) value is true

But can i put dynamic varables into this ['checkboxname'] since am generating the name dynamically?

it does not matter wether names are set up as a HTML static code or are dynamically generated. The condition is that those checkboxes to have a unique name

<input name="blabla0" type="checkbox">
<input name="blabla1" type="checkbox">
..

If you use an incremental type name (blablai), you may later simplify the code using a for loop.

You may also use the order of elemets, not necessarily the name, as the general reference is

document.forms[name_or_order].elements[name_or_order].attribute

In this case you have to build first an array with the elements who have the same type (type="checkbox" in your case)
