function zipcode_detect(){
	
	
	var albay_zipcode = Array("4509","4502","4501","4503","4515","4500","4507","4504","4510","4512","4514","4504","4516","4506","4517","4508","4511","4513");

var albay_town = Array("bacacay","camalig","daraga","guinobatan","jovellar","legazpi city","libon","ligao","malilipot","malinao","manito","oas","pio duran","polangui","rapu-rapu","sto. domingo","tabaco","tiwi");

var ddf = document.form_zip.addrz.value;
		
		
	for(var count = 0; count<18; count++ ){
		var input = ddf.match(albay_town[count]);	
		if(input){
			alert('match '+albay_zipcode[count]);
			
		}else{
			alert('not');	
			
		}
	}
}//end of function

i want to check if the value of my textfield has a word match in my array albay_town widthout using the for loop.
example input: camalig, albay;
the output must be: match 4502;
can you help me please. . . :)

You can use the indexOf method of the array class to look for the position matching a specified value.

However, you will get no results in your example case because you're looking for "camalig, albay" and there is no such value in your array. You only have "camalig" in your array.

var ddf = document.form_zip.addrz.value;
var input = ddf.toLowerCase();    
 
    for(var count = 0; count<18; count++ ){
 	if(input.match(albay_town[count])){
		alert('match '+albay_zipcode[count]);
		break;
	}     
    }
}//end of function
