Can't use getElementsByTagName.length value as loop parameter

adas007

I have following code in sahi script:

var $inputLength = document.getElementsByTagName("button").length;

_alert($inputLength);


for(var $i=0; $i<$inputLength; $i++)
{
_alert("test");

}

Result is:

_alert($inputLength); -> gives me 21 in popup

but

for loop doesn't start code inside brackets. I don't know why "$inputLength" value isn't assigned as 21 number ? Is "21" a string ?

I see that _alert(typeof $inputLength); gives a number, so whyd loop can't be started?

as far as i know, there is a bug in the Javascript engine so you can't use

if ()
{
}

you have to write it as

if () {
}

if this does not fix it, try to use

var $inputLength = 0
_set(inputLength ,document.getElementsByTagName("button").length);
for(var $i=0; $i<$inputLength; $i++) {
_alert("test");
}
