validate a textarea only if a certain value is selected in another field

[Josh]

Is it possible to make a textarea required only if a certain value is
selected from a <select>?

I am trying to make a textarea named ObjOther required only if the
value OT is selected from a drop down list named Dmost. Is this
possible to do client side using javascript or do I need to look into
trying this in another language? Thanks in advance for your help.

// f = the form you're validating
if(f.Dmost.options[f.Dmost.selectedIndex].value=="OT"){
// validate ObjOther
}
