    Hi!
    this is a script that refers to the object and property self.location:
    
<SCRIPT language=JavaScript>
function reload(form){
var val=form.cat.options[form.cat.options.selectedIndex].value; 
[COLOR="RoyalBlue"]self.location='dd.php?cat=' + val ;[/COLOR]
}
</script>

]
    Code (markup):
    Can anyone explain me the last blue command? what does self.location means ? and what is the meaning of this syntax: cat=' + val ?

    as u can see i didn't wrote the script but i have to understand the syntax..


    Thanx

    the line in blue is what actually performs the browser redirect

    the browser will redirect to a file in the current folder named dd.php and passing variable cat along the url with the value of the variable named val.
