Cut to Size, Custom, ASP, Javascript

hello Javascript programmers,

 

in the previous article and post, the cut to size shape is different than full sheet in javascript is where the hard work came in.. the actual database entries for pricing for full versus cut sheet was the trigger to determine price per square feet, either by cut to size versus full sheet... here is the math

 

 

 
  < % if sheet_style = "full_sheet" then % >
    <input type="text" size="3" name="subproduct_quantity" value="0" OnChange="var myval; myval = (32 * document.subproduct< %=rs("subproduct_id")% >.subproduct_price.value) * document.subproduct< %=rs("subproduct_id")% >.subproduct_quantity.value; myval = Math.round(myval * 100) / 100; document.subproduct< %=rs("subproduct_id")% >.subproduct_extendedprice.value = '$' + myval.toFixed(2) ;">
    < % end if % >
    < % if sheet_style = "cut_to_size" then % >
    <input type="hidden" name="cut_to_size_length" size="3" value="0"><input type="hidden" name="cut_to_size_width" size="3" value="0">
    <input type="text" size="3" name="subproduct_quantity" value="0" OnChange="document.subproduct< %=rs("subproduct_id")% >.cut_to_size_length.value=document.cut_to_size_values.length.value;document.subproduct< %=rs("subproduct_id")% >.cut_to_size_width.value=document.cut_to_size_values.width.value;var myval; myval = (((document.cut_to_size_values.length.value * document.cut_to_size_values.width.value) / 144 )* document.subproduct< %=rs("subproduct_id")% >.subproduct_price.value) * document.subproduct< %=rs("subproduct_id")% >.subproduct_quantity.value; myval = Math.round(myval * 100) / 100; document.subproduct< %=rs("subproduct_id")% >.subproduct_extendedprice.value = '$' + myval.toFixed(2) ;">
    < % end if % >
