javascript null..is it a string?

[adrive]

hi, i'm wondering why is it javascript doesn't seem to accept null value as a real null? In order to know if its a null field later on, it's as if i have to check it against a string 'null'.

for example,
i have a txtName hidden field on my html.

I use javascript to

document.myForm.txtName.value = null;

later on, when i try to detect it just doesn't work :

if(document.myForm.txtName.value == null){
 alert('value is null');
}else if(document.myForm.txtName.value == 'null'){
 alert('value is a string null'); //only this works!
}

hi ...

ALL values that you retrieve from a page/field are handled as strings ... since the value is considered as the nodeValue of a textnode ...

kind regards
