假设您有以下html

<table>
<tr id="hourly">
    <td>
        <input value="1" />
        <input value="2" />
        <input id="total_hour" />
    </td>
</tr>
</table>
<button id="calc">Submit</button>

以下 JS 应该可以满足您的需求。

//-- Create an empty array to hold items
var items = [];

//-- set hourly total = 0
var htotal = 0;

//-- When submit is clicked process hourly time, this should be repeated for each row

    $("#calc").click(function () {
//-- use the each function to loop through every input field on the hourly row

        $("#hourly input").each(function () {

//-- only the final total has an id and we don't want that included in our total

          if(!$(this).attr("id"))
          {

            //-- convert each value to a number and push to items array
            items.push(parseFloat($(this).val()));

          }



    });
//-- loop through each item in the items array
      $.each(items, function() {
//-- add the items together as the htotal variable
              htotal += this;
      });
//-- set the total_hour value to htotal
    $("#total_hour").val(htotal);

    });
