javascript: loop through items

[kristof_v]

hi,

i have 4 input fields:
txt1
txt2
txt3
txt4

now i have a for loop like:
for (var i=0; i<4; i++) {
txt+i.value = parseFloat(txt+i.value) * 2
}

i need to append the i value to txt so i don't to write 4 lines of code.
but i don't know how to do this in javascript?

grtz

eval("txt"+i+".value = parseFloat(txt"+i+".value) * 2");
}
