Append string to the end of string via a loop

[l_kris06]

Hi all,

I am trying to append a string with some more string data. This sounds simple, but I am unable to do it.

This is what i am trying to do:

<script>
for(var i = 0; i<10;i++){
appendString += "This is number "+i+"<BR>";
}

document.write(appendString);
</script>

I want my output to be,
This is number 1
This is number 2
This is number 3
.
.
.

However this doesnt work. Can somebody help me understand why ?

OK, I fixed it, looks like the variable needs to be initialized before being using it in the loop.

fixed code:

<script>
appendString='';
for(var i = 0; i<10;i++){
appendString += "This is number "+i+"<BR>";
}

document.write(appendString);
</script>
