Question

I’m trying to write a simple for loop and I keep getting this error:

missing ; after for loop initializer.

I can’t seem to figure out why. cleari is an array of input fields. So, I’m basically trying to take each field in the array, and reset it:

var cleari = document.getElementById(rowNum).getElementsByTagName('input');
for (cleari) {
    cleari.parentNode.innerHTML = cleari.parentNode.innerHTML;
}

Answer 1

A for loop is of the convention for(a;b;c)

For example:

for(var i = 0; i < 10; ++i)  {
     alert(i);
} 

A while loop is of the convention while(a)

For example:

var i = 0;
while(i < 10){
    alert(i);
    ++i;
}

So for your example what you can do is:

for(var i = 0; i < cleari.length; i++){
    cleari[i].parentNode.innerHTML = cleari[i].parentNode.innerHTML;
}
