Hi, how I can put the value of variable (i) in brackets?












-2















For example I have N input, each input have some id wath start with 1 to N,
the input are not includes in FORM



With JS function I want to display the id of checked input
I try to do this like in example



for (i = 1; i <= count; i++) 
{ if (document.getElementById('i').checked == true)
{ alert("id of checked element is:"+i);
}
}


How can I put the value of i here inside the brackets ?



{   if (document.getElementById('i').checked == true)

  • Well you are looking for the string "i", not the variable

  • () are typically called parenthesis, not brackets.
