I'm not sure exactly how to do this. I have a file called datafile.js. I have another file called Objects.js. I have another file called sales.html to bring it alll together.

Here is datafile.js, which I created to test my other stuff:
//datafile.js
var datafile = new Array();
datafile.push("Smith,Mary:9/9/2001:sw:5000:24000");
datafile.push("Wilen, Bill:4/18/1994:ne:4000:26000");
datafile.push("Wang, Chon:7/1/1998:ne:6000:30000");
datafile.push("Normal, Abi:1/21/2000:nw:10000:25000");
datafile.push("Arnold, Sarah:10/16/1990:sw:2000:27000");
datafile.push("Lowe, Sam:1/13/1992:sw:2000:24500");
datafile.push("Brody, Louise:1/26/1998:ne:3000:28000");
datafile.push("Chee, James:4/15/2004:sw:3200:25000");
datafile.push("Webb, Jack:11/4/2002:nw:6500:32500");
datafile.push("Mann, Beth:11/4/2006:nw:6500:32500");
datafile.push(":11/4/2002:nw:6500:32500");
datafile.push("Nabo, Ned:8/4/2003:nw:7100:-30900");
datafile.push("Inderfurth, Apo:2/4/2000:xw:3100:9900");


Here is Objects.js, which I'm using for all of my functions and to sort through the data:

//Objects.js
function verify(Employee){
alert("Just added "+Employee.name+".");
}

function Employee(name, dateOfHire, division, sales, salary){
this.name=name;
this.dateOfHire=dateOfHire;
this.division=division;
this.sales=sales;
this.salary=salary;
this.show=showAll;
verify(this);
this.empNo=++Employee.key;
}
Employee.key=0;


function showAll(){
document.writeln(this.name+"<br>");
document.writeln(this.dateOfHire+"<br>");
document.writeln(this.division+"<br>");
document.writeln(this.sales+"<br>");
document.writeln(this.salary+"<br>");
}


var workers=new Array();
function stepThru(){
for(i=0;i<datafile.length;i++){
workers[i]=new Array();
workersAttr=datafile[i].split(':');
for (j=0;j<workersAttr.length;j++){
workers[i][j]=workersAttr[j];
}
}
}



And this is what I'm using to bring it all together:
//sales.html
<html>
<head>
<style type = "text/css">
table{font-family: verdana,arial,sans-serif;
font-size: .7em;}
</style>
<script src = "datafile.js" type = "text/javascript"></script>
<script src = "Objects.js" type = "text/javascript"></script>
<script type = "text/javascript">
</script>
</head>
<body onload="stepThru();">
<table>
</table>
</body>
</html>

I can recreate the results from stepThru() manually to instantiate a new Employee, but I can't figure out how to do it automatically each time a new datafile is added to datafile.js.

This is what I did when I was trying to see if my object would work in the first place:
var workers = new Array();
workers[workers.length] = new Employee("Smith, Mary","9/9/2001","sw",5000,24000);

Would somebody explain to me how to instantiate the Employee object straight from the stepThru function?

var workers=new Array();
function stepThru(){
for(i=0;i<datafile.length;i++){
// extract name, dateOfHire... here (from datafile[i])
workers[i] = new Employee(name, dateOfHire...)
}
}

Thanks for the reply. Are you saying I should forget about splitting the records up right there and split them up somewhere else?

Anybody have any ideas about this?

Your questions was:Would somebody explain to me how to instantiate the Employee object straight from the stepThru function?
You can extract data at any place, prior to creating of a new instance of Employee.

It is possible you want to do something else hat is not clearly understandible. If this is the case try to rephrase the question.

Oh, sorry about that and thanks for replying, I've been having trouble with this for quite a while.

The datafile which I've been given to work from is an array of records and all of the attributes are separated by a colon. I wanted to step through the records and split each attribute on the colons. Then I created an array of arrays out of it so that I can access them like this: array[1][0] where the first index is the full record and the second index is a particular attribute of that record. I can't figure out how to get each one of these into a function constructor I made. I'd like to do it something like this:

var workers=new Array();
function stepThru(){
for(i=0;i<datafile.length;i++){
workers[i]=new Array();
workersAttr=datafile[i].split(':');
for (j=0;j<workersAttr.length;j++){
workers[i][j]=workersAttr[j];
/*I'd like to instantiate or create an instance of the object right here, but everything I've tried so far hasn't worked. If I can get it into the constructor from right here, then I can start working with it from the object and start adding my methods to it. Do I need to add another for loop for that?*/
}
}

Again, thanks for the help and for your patience. I appreciate it.
