在多个复选框中，如何存储一个答案 JQuery Mobile

Question

我每页有多个问题。问题是如果我回答第一个问题，然后当我检查第二个问题的答案时，第一个问题的答案将被取消选中，我的目标是每个问题只有一个答案并且答案将被存储。

$('input.answer').on('change', function() {
    $('input.answer').not(this).prop('checked', false);  
$('input.answer').not(this).prop('checked', false).checkboxradio("refresh");
});

Answer 1

在您的 jquery 代码中，您必须指明仅使用所选复选框的字段集...

$('input.answer').on('change', function() {

    $(this).closest('fieldset').find('input.answer').not(this).prop('checked',false).checkboxradio("refresh");  

});
