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;
}
I think you might have been looking for the for...in loop:
var clearis = document.getElementById(rowNum).getElementsByTagName('input');
for(cleari in clearis)
{
clearis[cleari].parentNode.innerHTML = clearis[cleari].parentNode.innerHTML;
}
You can read more about the for...in loop at the Mozilla Developer Network
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;
}
