Delivery charge program

@viper12May 13.2007

It’s just a work in progress at the moment, but I’d appreciate some help, again.

I’m writing a program for a delivery service where there are following conditions.

For orders worth less than £25 the delivery charge is £3.00.

Orders worth at least £25 but less than £100 are delivered free.
Orders worth £100 or more are delivered free and in addition the
customer receives a free gift. I prompt the user to enter the order value, and tell him/her which band he comes under.

This is what I have so far, and it doesn’t seem to be it, evidently.

[code] <html> <body> <script type=’text/javascript’> // A delivery charge program

var ordervalue // how much the order is worth ordervalue = window.prompt (‘How much is the order worth in Pounds Sterling?’,”); document.write (‘The value of your order is £’ + ordervalue + ‘.<BR>’); if ordervalue =< 25 { document.write(‘Your delivery will cost £3 as your order value is’ + ‘£’ + ordervalue + ‘.<BR>’); if ordervalue > 25 and ordervalue < 100 document.write(‘Your delivery is free as your order value is’ + ‘£’ + ordervalue + ‘.<BR>’); else document.write (‘You will receive a free gift and delivery is free as your order value is’ + ‘£’ + ordervalue + ‘.<BR>’); } </script> </body> </html> [/code]

This is untested and likely to be buggy but you really should pay a site like :http://www.htmlgoodies.com/ a visit, it will help you understand how 2 write scripts.

@viper12authorMay 13.2007 — #It doesn't work, sadly. Thanks for trying though.

@viper12authorMay 13.2007 — #Anyopne else know what to do? I'm eager to find out, and can't sleep now.

 &lt;head&gt; DELIVERY CHARGE PROGRAM &lt;/head&gt;
 
 &lt;br&gt;
 
 &lt;script type="text/javascript"&gt;
 /* Program to provide descriptive information about the orderValue, given its value */
 
 var orderValue 
 
 orderValue = window.prompt('How much is the order worth in Pounds Sterling?','');
 orderValue = parseFloat(orderValue);
 var orderString;
 
 if(orderValue &lt; 25) 
 {
 orderString = "£3.00";
 orderValue += 3;
 }
 else if(orderValue &lt; 100.00) 
 {
 orderString= "free";
 }
 else 
 {
 orderString = "free with free gift";
 }  <br/>
 orderValue = orderValue.toFixed(2);
 document.write('Delivery charge is ' + orderString + '. The value of your order is £' + orderValue + '.&lt;br /&gt;');
 document.write('&lt;br /&gt;');
 &lt;/script&gt;
 &lt;body&gt;
 &lt;html&gt;

Now this works just fine in an HTML editing program called Taco HTML I use on my Mac, but it doesn't seem to execute in firefox, can someone help please?

@boskoMay 13.2007 — #Based on . changes:

[CODE]<html>
 <body> 
 <script type='text/javascript'> 
 // A delivery charge program var ordervalue 
 // how much the order is worth 
 var ordervalue = window.prompt('How much is the order worth in Pounds Sterling?',''); 

 var str = 'The value of your order is £' + ordervalue + '<br>'; 
 if (ordervalue <= 25) 
 str ='Your delivery will cost £3 as your order value is £' + ordervalue; 
 if (ordervalue > 25 &&  ordervalue < 100){ 

 str ='Your delivery is free as your order value is £' + ordervalue; 

 }
 else 
 str ='You will receive a free gift and delivery is free as your order value is £' + ordervalue; 
 alert(str); 
 // to output a result to see it is works! 
 </script>
 </body>
 </html>[/CODE]

@viper12authorMay 13.2007 — #That one doesn't work proper, bosko, the code I've just pasted does, but for some reason, not in an internet browser.

@rootMay 13.2007 — #I just tested it and it works perfectly fine thank you. except for the buggy bit I mentioned, something in the logic int right!

@rootMay 13.2007 — #here:

&lt;html&gt;
 &lt;body&gt; 
 &lt;script type='text/javascript'&gt; 
 // A delivery charge program var ordervalue 
 // how much the order is worth 
 var ordervalue = window.prompt('How much is the order worth in Pounds Sterling?','') -0;  <br/>
 var str = 'The value of your order is £' + ordervalue + '&lt;br&gt;'; 
 if (ordervalue &lt;= 25) 
 str ='Your delivery will cost £3 as your order value is £' + ordervalue; 
 if (ordervalue &gt; 25 &amp;&amp;  ordervalue &lt; 100){  <br/>
 str ='Your delivery is free as your order value is £' + ordervalue;  <br/>
 }
 else if(ordervalue &gt;=100){
 str ='You will receive a free gift and delivery is free as your order value is £' + ordervalue;} 
 alert(str); 
 // to output a result to see it is works! 
 &lt;/script&gt;
 &lt;/body&gt;
 &lt;/html&gt;

WORKS.

@rootMay 13.2007 — #NOTE the -0; on the end of the prompt, this turns a string numeric into a number numeric so you can add, subtract, divid, etc

@viper12authorMay 13.2007 — #It seems to work to the point that it accepts the value, but doesn't print whether the order delivery costs 3 quid, free or free with a gift, ..

That's the key part, aye.

I take that back, it works, it works.

Thanks a lot slash slash. ?

@rootMay 13.2007 — #The NEW one works.... I put 15 into the box and the £3 thing poped up. I put 50 in and it says free delivery, and put a ton in and its offering me a freebie.

Edit:

K, I was beginning to wonder!

@rootMay 13.2007 — #One thing tho...

str += '... for the remaining 3 str = but not the first, this is because your adding to the string and not setting, my typo error...!

@viper12authorMay 13.2007 — #Thanks a lot, mate, most thankful I am. Yoda, style.
