使用MEF时是否有任何棱镜“后构建”事件或方法？(Are there any Prism “Post-build” Event or method while using MEF?)

 我发现的第一个也是最明显的错误是命令“add + = parseFloat（this.value）;” 不起作用。 
 
 正确的功能如下： 
 
function calculateRow() {
   alert("GAYA");
   console.log("2");
   var add = 0;
   $(".qty").each(function() {
       add += parseFloat($(this).val()); // <-- changed from this.value
       if (isNaN(add)) {
           $('#total').val("0");
       } else {
           $('#total').val(add.toFixed(2));
       }
   });
}
 
 您还必须更改以下行 
 
$('#detail').on('keyup', '.qty', calculateRow());
 
 至 
 
$('#detail').on('keyup', '.qty', calculateRow);

Tthe first and most obvious error I found was that the command "add += parseFloat(this.value);" does not work.
 
The correct functions would be the following:
 
function calculateRow() {
   alert("GAYA");
   console.log("2");
   var add = 0;
   $(".qty").each(function() {
       add += parseFloat($(this).val()); // <-- changed from this.value
       if (isNaN(add)) {
           $('#total').val("0");
       } else {
           $('#total').val(add.toFixed(2));
       }
   });
}
 
You also have to change the following row from
 
$('#detail').on('keyup', '.qty', calculateRow());
 
to
 
$('#detail').on('keyup', '.qty', calculateRow);
