Question

＆＃13;

＆＃13;

$(document).ready(function() {


  $('.allrb').change(function() {
    valueE();
  });

});  


function valueE()
{
  for(j=0; j<=2 ; j++)
  {
    var nofr1=[];  
    row=document.getElementsByName("Fr"+j);
      for (i=0; i<row.length; i++)
      {
        if(row[i].checked)
          nofr1[i]= parseInt(row.value);
      }
    $("#numFr"+(j+1)).val(nofr1[j]); 
  }
}

在一行中，我有2个不同的收音机盒，如何获取所有收音机盒的值并在那里设置特定input[type=number]的值？由于我有16行，每行有2个不同的值框，我想使用循环将所有值循环到特定的位置，否则会有很多冗余代码。我试过这样做，但我的jquery不会工作。感谢。

可以在事件中引用已更改的元素。如果您要输入要更新公共类的输入，则可以通过查找无线电父级tr并在其中查找该类来找到与您的无线电相关的输入。

$(document).ready(function() {
  $('.allrb').change(valueE);
});


function valueE(e) {
  var newValue = e.target.value;
  var $radio = $(e.target);
  
  if ($radio.is('.Fr')) {
    $radio.closest('tr').find('.numFr').val(newValue);
  } else {
    $radio.closest('tr').find('.numIr').val(newValue);
  }
}

Answer 2

这应该适合您，而无需更改HTML：

while true do
  io.write("PIN: ")
  local pin = tonumber(io.read("*line"))
  if pin == 21171 then
      -- code
  elseif pin == 21172 then
      -- code
  end -- if
end -- while

但是，这不适用于您最后一行的第一个广播组，因为您输入的内容为$(document).ready(function() { $('.allrb').change(valueE); }); function valueE(e) { var index = $(this).closest("tr").index(); var newValue = e.target.value; if ($(this).closest("td").attr("bgcolor") == "Gainsboro"){ $("#numIr" + (index + 1)).val(newValue); }else $("#numFr" + (index + 1)).val(newValue); } ，我认为您打算将其标记为id="numFr2"一旦您更正名称，它就会也为那个人工作。
