Below is my javascript.  It's for printing out coupons.  As you can see I'm manually specifying if ss_quantity equals 1 do the 8 document.write stuff which prints out the coupon and if ss_quantity equals 2 do the 8 document.write stuff times 2.  In my real script I have this up to 10 but I want to do a loop for this so that if the quantity is 2 it loops through the coupon twice, if 3 it loops 3 times, etc.  I think I need to do nested "for" loops but I'm pretty new to this stuff and would like some help.  Thanks.

 

<script type="text/javascript">

<!--

 

for (i = 0; i < number_products; i++) {

        if (ss_weight == 0.000000 && ss_quantity == 1) {

 

        document.write ("<div id=\"coupon1\"><img src=\"design/coupon.png\"></div><div id=\"coupon2\">");

                document.write(ss_name);

        document.write("</div>");

        document.write ("<div id=\"coupon3\">Order Number:");

        document.write (ss_ordernum);

        document.write ("&nbsp&nbsp&nbsp&nbsp&nbspExpires: ");

                document.write(Date.today().add({months: 6}).toString("M-d-yyyy"));

        document.write ("</div><br><br><br><br><br><br><br>");

 

}

else if (ss_weight == 0.000000 && ss_quantity == 2) {

 

        document.write ("<div id=\"coupon1\"><img src=\"design/coupon.png\"></div><div id=\"coupon2\">");

                document.write(ss_name);

        document.write("</div>");

        document.write ("<div id=\"coupon3\">Order Number:");

        document.write (ss_ordernum);

        document.write ("&nbsp&nbsp&nbsp&nbsp&nbspExpires: ");

                document.write(Date.today().add({months: 6}).toString("M-d-yyyy"));

        document.write ("</div><br><br><br><br><br><br><br>");

        document.write ("<div id=\"coupon1\"><img src=\"design/coupon.png\"></div><div id=\"coupon2\">");

                document.write(ss_name);

        document.write("</div>");

        document.write ("<div id=\"coupon3\">Order Number:");

        document.write (ss_ordernum);

        document.write ("&nbsp&nbsp&nbsp&nbsp&nbspExpires: ");

                document.write(Date.today().add({months: 6}).toString("M-d-yyyy"));

        document.write ("</div><br><br><br><br><br><br><br>");

 

}

else{

        }

}

It might be easier to see it in action.  If you view the page source you should be able to see what I'm trying to do.  I have products that are shipped that I don't want to print out a coupon for which is why I have the last else statement.  Here's a link of it in action:

I think your kinda missing the point of the for loop and automation in general. The theory behind it is, write it once, then loop over it x amount of times. So basically you shouldn't need that massive if/else statement inside of your for loop.

 

Here's how it should look:

<script>
var i, x;
var products = new Array;

//you'll probably be creating the array with php, but here's a hard coded one
products['ordernum'] = 12345678;
products[0] = new Array;
products[0]['name'] = 'Name1';
products[0]['quantity'] = 1;
products[0]['weight'] = 0.000000;
products[1] = new Array;
products[1]['name'] = 'Name2';
products[1]['quantity'] = 1;
products[1]['weight'] = 0.000000;
products[2] = new Array;
products[2]['name'] = 'Name3';
products[2]['quantity'] = 1;
products[2]['weight'] = 0.000000;

for(i in products){
        if( products[i]['weight'] == 0.000000 ){
                x = 0;
                for(x; x < products[i]['quantity']; x++){
                        document.write ("<div id=\"coupon1\"><img src=\"design/coupon.png\"></div><div id=\"coupon2\">");
                        document.write(products[i]['name']);
                        document.write("</div>");
                        document.write ("<div id=\"coupon3\">Order Number:");
                        document.write (products['ordernum']);
                        document.write ("&nbsp&nbsp&nbsp&nbsp&nbspExpires: ");
                        document.write(Date.today().add({months: 6}).toString("M-d-yyyy"));
                        document.write ("</div><br><br><br><br><br><br><br>");
                }
        }
}
</script>

 

Hopefully that will give you a better idea of how to better organize your loops and products array. Let me know if you have anymore questions on it.

I found some bugs in my last code sample, this one is tested and working:

<html>
<body>
<script>
var products = new Array;
var expires  = new Date();
var dd = expires.getDate();
var mm = expires.getMonth()+7; //January is 0!
var yyyy = expires.getFullYear();
if(dd<10){dd='0'+dd} if(mm<10){mm='0'+mm} expires = mm+'/'+dd+'/'+yyyy;

//you'll probably be creating the array with php, but here's a hard coded one
products['ordernum'] = 12345678;
products[0] = new Array;
products[0]['name'] = 'Name1';
products[0]['quantity'] = 2;
products[0]['weight'] = 0.000000;
products[1] = new Array;
products[1]['name'] = 'Name2';
products[1]['quantity'] = 1;
products[1]['weight'] = 0.000000;
products[2] = new Array;
products[2]['name'] = 'Name3';
products[2]['quantity'] = 1;
products[2]['weight'] = 0.000000;

var output = '';
for(var i in products){
        if( products[i]['weight'] == 0.000000 ){
                for(x=0; x < products[i]['quantity']; x++){
                        output = output + "<div id=\"coupon1\"><img src=\"design/coupon.png\"></div><div id=\"coupon2\">";
                        output = output + products[i]['name'];
                        output = output + "</div>";
                        output = output + "<div id=\"coupon3\">Order Number:";
                        output = output + products['ordernum'];
                        output = output + "&nbsp&nbsp&nbsp&nbsp&nbspExpires: ";
                        output = output + expires;
                        output = output + "</div><br><br><br><br><br><br><br>";
                }
        }
}

document.write( output );
</script>
</body>

The code below is the javascript I can't change.  This javascript is written with a CGI script which is really complex.  I might be able to modify it but then I could mess up the shopping cart so I really don't want to try to change it.  Any ideas?  I've been trying to figure this out for a long time.  Thanks!

It will still work similarly. Since each field is built into an array with corresponding keys.

 

CHeck it:

<html>
<body>
<script>
var ss_ordernum = "1322";
var ss_name = new Array;
var ss_quantity = new Array;
var ss_weight = new Array;
ss_name[0] = 'Name1';
ss_quantity[0] = 2;
ss_weight[0] = 0.000000;
ss_name[1] = 'Name2';
ss_quantity[1] = 1;
ss_weight[1] = 0.000000;
ss_name[2] = 'Name3';
ss_quantity[2] = 1;
ss_weight[2] = 0.000000;
var number_products = 3;

//CODE YOU NEED STARTS HERE
var expires  = new Date();
var dd = expires.getDate();
var mm = expires.getMonth()+7; //January is 0!
var yyyy = expires.getFullYear();
if(dd<10){dd='0'+dd} if(mm<10){mm='0'+mm} expires = mm+'/'+dd+'/'+yyyy;

var output = '';
for(i in ss_name){
        if( ss_weight[i] == 0.000000 ){
                for(x=0; x < ss_quantity[i]; x++){
                        output = output + "<div id=\"coupon1\"><img src=\"design/coupon.png\"></div><div id=\"coupon2\">";
                        output = output + ss_name[i];
                        output = output + "</div>";
                        output = output + "<div id=\"coupon3\">Order Number:";
                        output = output + ss_ordernum;
                        output = output + "&nbsp&nbsp&nbsp&nbsp&nbspExpires: ";
                        output = output + expires;
                        output = output + "</div><br><br><br><br><br><br><br>";
                }
        }
}

document.write( output );
</script>
</body>
</html>

It's almost exactly the same,(I DIDN'T TEST THIS ONE, BUT IT SHOULD BE OK), the only difference is I was using a multi-dimensional array before, which would have been a little bit more organized in my opinion, but either way works.

 

Let me know how that works out for you.
