ここには、配列 (setArray と呼ばれる) に既にデータが含まれているコードがいくつかあります。そして、transArray の長さに応じてそのデータをループし、ランダム データをテキスト ボックス フィールドに入れます。完全なコードは次のとおりです: http://jsfiddle.net/EABRJ/

var loadBills = function ()
{

clearFields();

mySetArray();  //Fills the transArray randomly with 1-4 items   

// TEMPORARY ALERT BELOW SO YOU CAN SEE THAT THE ARRAY IS BEING LOADED

//  alert(transArray);      

     for ( var i = 0; i <= transArray.length; i++)
    {
         var items = 'item' + i;
         var amounts = 'amount' + i;    
         splittedData = transArray[i].split(":");
         items.value += splittedData[0];
         amounts.value += splittedData[1];          
    }
}

var clearFields = function ()
{

    for ( i = 1; i <= 4; i++)
    {
     itemName = 'item' + i;
     $(itemName).value = "";
    }
    for ( i = 1; i <= 4; i++)
    {
     amountName = 'amount' + i;
     $(amountName).value = "";
    }
       $('total').value = "";   
   }

var mySetArray = function ()
{

 var myRandom = Math.floor((Math.random() * 100) / 25) + 1;  //a number between 1    and 4

 transArray = new Array();  //Resets the Array to empty

 if (myRandom == 1)
 {
    transArray[0] = "Food:200";
 }

 if (myRandom == 2)
 {
    transArray[0] = "Food:200";
    transArray[1] = "Toys:700";
 }

 if (myRandom == 3)
 {
    transArray[0] = "Food:200";
    transArray[1] = "Toys:700";
    transArray[2] = "Mortgage:1800";
 }

 if (myRandom == 4)
 {
    transArray[0] = "Food:200";
    transArray[1] = "Toys:700";
    transArray[2] = "Mortgage:1800";
    transArray[3] = "Cable:130";
 }
}

    window.onload = function ()
