Variable declaration

[El_Dudereno]

I am trying to declare the following variables in a .js file.

 

dow = f or s

cdate = a to p except n

ctime = a to f

city = 0 to 36

 

The problem i have is that i am not sure i have declared the variables correctly, and if i haven't how to correct it.

The code below is my declaration as it is on the page. These variables are called to another page to be used so would there have to be any tags around the code or is it fine without any?

Also if I was to add more functions to this page would they have to go in any tags?

 

My variables:

 

 

 

dow=new Array();

dow[0]=new Array("f");

dow[1]=new Array("s");

 

cdate=new Array();

cdate[0]=new Array("a");

cdate[1]=new Array("b");

cdate[2]=new Array("c");

cdate[3]=new Array("d");

cdate[4]=new Array("e");

cdate[5]=new Array("f");

cdate[6]=new Array("g");

cdate[7]=new Array("h");

cdate[8]=new Array("i");

cdate[9]=new Array("j");

cdate[10]=new Array("k");

cdate[11]=new Array("l");

cdate[12]=new Array("m");

cdate[13]=new Array("o");

cdate[14]=new Array("p");

 

ctime=new Array();

ctime[0]=new Array("a");

ctime[1]=new Array("b");

ctime[2]=new Array("c");

ctime[3]=new Array("d");

ctime[4]=new Array("e");

ctime[5]=new Array("f");

 

city=new Array();

city[0]=new Array("0");

city[1]=new Array("1");

city[2]=new Array("2");

city[3]=new Array("3");

city[4]=new Array("4");

city[5]=new Array("5");

city[6]=new Array("6");

city[7]=new Array("7");

city[8]=new Array("8");

city[9]=new Array("9");

city[10]=new Array("10");

city[11]=new Array("11");

city[12]=new Array("12");

city[13]=new Array("13");

city[14]=new Array("14");

city[15]=new Array("15");

city[16]=new Array("16");

city[17]=new Array("17");

city[18]=new Array("18");

city[19]=new Array("19");

city[20]=new Array("20");

city[21]=new Array("21");

city[22]=new Array("22");

city[23]=new Array("23");

city[24]=new Array("24");

city[25]=new Array("25");

city[26]=new Array("26");

city[27]=new Array("27");

city[28]=new Array("28");

city[29]=new Array("29");

city[30]=new Array("30");

city[31]=new Array("31");

city[32]=new Array("32");

city[33]=new Array("33");

city[34]=new Array("34");

city[35]=new Array("35");

city[36]=new Array("36");

Your question really doesn't make any sense. Declaring a variable and assigning a value are two different things. Are you saying you want to randomly assign a value to those variables from the arrays? If that is the case then a simple function to randomly return a value from an array is all you need.

 

function getRandFromArray(array)
{
     return array[Math.floor(Math.random()*array.length)];
}

 

Then, to assign a random value from the 'dow' array to another variable just do this

 

var randDOW = getRandFromArray(dow);

 

Also, since your arrays are sequentially based starting at 0, a more efficient way to create them would be like so:

var dow = new Array('f', 's');

var cdate = new Array (
    'a', 'b', 'c', 'd', 'e', 'f', 'g',
    'h', 'i', 'j', 'k', 'l', 'm', 'o', 'p'
    );

var ctime = new Array('a', 'b', 'c', 'd', 'e', 'f');

var city = new Array(
     '0', '1', '2', '3', '4', '5', '6', '7', '8', '9',
    '10', '11', '12', '13', '14', '15', '16', '17', '18',
     '19', '20', '21', '22', '23', '24', '25', '26', '27',
     '28', '29', '30', '31', '32', '33', '34', '35', '36'
    );
