如何保存单选按钮的值。朋友已经做了这个以获得一个cookie。现在我需要进入下一步，但我不知道如何。

function saveForm（nForm）{

var nFields = nForm.length;
for (i=0; i<nFields; i++)
  {
   var isType = nForm[i].type;
   alert(isType);
   if (isType == 'radio'){alert('Field '+ i+ ' is a radio button')}
   if (isType == 'select-one'){alert('Field '+i + ' is a select list')}
  }

}

    <form onsubmit="return saveForm(this)">
      <input type = "radio" name = "staande_houding_globaal" value="0">
      0 </input>
      <input type = "radio" name = "staande_houding_globaal" value="1">
      1 </input>
      <input type = "radio" name = "staande_houding_globaal" value="2">
      2 </input>
      <input type = "radio" name = "staande_houding_globaal" value="3">
      3 </input>
      <input type = "radio" name = "staande_houding_globaal" value="4">
      4 </input>
      <input type = "radio" name = "staande_houding_globaal" value="5">
      5 </input>
      <input type = "radio" name = "staande_houding_globaal" value="6">
      6 </input>
      <input type = "radio" name = "staande_houding_globaal" value="7">
      7 </input>
      <input type="button" value="Volgende" onClick="history.forward()","saveState()" class = "volgende" />
    </form>

Answer 1

获取单选按钮的值尝试

$("input:radio[name=staande_houding_globaal]").click(function() {
alert($(this).val());
});

或

var xyz = $("input[name=staande_houding_globaal]:checked").val(); console.log(xyz);

使用此选项检查单选按钮是否已选中

$('input[name=staande_houding_globaal]').is(":checked");

这将返回一个布尔值
