首先,這是我第一個jQuery腳本,如果你有任何建議不要害羞。更改輸入類型,從單選按鈕複選框,jquery

我正在嘗試以下操作。我有3列單選按鈕。用上面的複選框。當我檢查其中一個複選框時,該列將從單選按鈕變爲複選框,並且此時只能更改一行。我的腳本正在做所有這些,但我有一個問題。當我更改類型時,所有輸入都會獲得第一個輸入的相同屬性。我想我應該有一些循環,但我完全不知道如何做到這一點。

所以,我的問題:我如何改變我的腳本,以便只改變類型而不改變其他屬性?

嗯,我並沒有停止努力,最後我得到了它與.each()循環工作。我也添加了2的複選框選擇限制。我是JQuery的新手,所以也許代碼並不像我想的那麼幹淨,但它看起來很完美。

https://jsfiddle.net/bjc3a9y7/2/

$('input[name="switch"]').change(function() { 
var checked = $(this).is(':checked'); 
$('input[name="switch"]').prop('checked',false); 

var arr = ["brand", "fuel", "body"]; 

$.each(arr, function(i, val) { 
    var type = $('input[name="' + val + '"]').prop("type"); 

    if (type == 'checkbox') { 
     $('input[name="' + val + '"]').each(function(index, value){ 
      var oldInput = $(value); 
      if(index == 0){ 
       $(value).replaceWith(
        $('<input type="radio" />'). 
        prop("value", oldInput.prop("value")). 
        prop("name", oldInput.prop("name")). 
        prop("id", oldInput.prop("id")). 
        prop('checked',true) 
       ) 
      } else { 
       $(value).replaceWith(
        $('<input type="radio" />'). 
        prop("value", oldInput.prop("value")). 
        prop("name", oldInput.prop("name")). 
        prop("id", oldInput.prop("id")) 
       ) 
      } 
     }); 
    }; 
}); 

if(checked) { 
    $(this).prop('checked',true); 
    var id = $(this).prop("id");       
    $('input[name="' + id + '"]').each(function(index, value){ 
     var oldInput = $(value); 

     var checked2 = $(value).is(':checked'); 
     if(checked2) { 
      $(value).replaceWith(
       $('<input type="checkbox" />'). 
       prop("value", oldInput.prop("value")). 
       prop("name", oldInput.prop("name")). 
       prop("id", oldInput.prop("id")). 
       prop('checked',true) 
      ) 
     }else{ 
      $(value).replaceWith(
       $('<input type="checkbox" />'). 
       prop("value", oldInput.prop("value")). 
       prop("name", oldInput.prop("name")). 
       prop("id", oldInput.prop("id")) 
      ) 
     } 
    }); 

    // limit selection checkboxes 
    $('input[name="' + id + '"]').change(function(){ 
     var max= 2; 
     if($('input[name="' + id + '"]:checked').length == max){ 
      $('input[name="' + id + '"]').prop('disabled', 'disabled'); 
      $('input[name="' + id + '"]:checked').removeProp('disabled'); 
     }else{ 
      $('input[name="' + id + '"]').removeProp('disabled'); 
     } 
    }); 
} 

});
