Question

根据选择的单选按钮，我在编辑复选框的禁用值和值属性时遇到问题。

当我选择输入#package-1然后输入＃突出显示时，该功能有效。但是，当我再次选择输入#package 1时失败。当我这样做时，复选框上的值不会改变（这是不正确的）但禁用了属性（这是正确的）。

非常感谢任何帮助。

$(document).ready(function(){
    $('.package-select').change(function(){
       if ($('#package-2').is(':checked') || $('#package-1').is(':checked') ){
             $('input#extrasRouter').removeAttr('disabled');
             $('input#extrasRouter').val("36-Wireless router - &pound;44.99 - TEST"); // Changing value to select the PAID FOR router 

         } else {
             $('input#extrasRouter').val("21-Wireless router - FREE");
             $('input#extrasRouter').attr('disabled', true);     
         }   
    });
});

Answer 1

checked是属性，不是属性。改变这些：

$('input#extrasRouter').removeAttr('disabled');
...
$('input#extrasRouter').attr('disabled', true);

到这些：

$('input#extrasRouter').prop('disabled', false);
...
$('input#extrasRouter').prop('disabled', true);

尝试在重新启用之前设置值，而不是在禁用该框时设置值。

根据单选按钮选择更改禁用复选框的值属性时出现问题
