Question

Male <input value="V1" checked="checked" name="R1" type="radio">
Female: <input name="R1" value="V2" type="radio"></p>


<input name="C1" value="ON" type="checkbox">Reading 
<input name="C2" value="ON" type="checkbox">Dressing 
<input name="C3" value="ON" type="checkbox">Make up
<input name="C4" value="ON" type="checkbox">Playing

请考虑以下情况：

这里检查MAle单选按钮。我想复选框阅读和播放应该自动检查＆lt;默认或＆gt;

假设女性检查 - 化妆和敷料

我想自动检查

Answer 1

    function select_radio(val){
      if (val=="male"){
    document.getElementById("C1").checked = true;
    document.getElementById("C2").checked = true;
    document.getElementById("C3").checked = false;
    document.getElementById("C4").checked = false;
      }
      else{
    document.getElementById("C3").checked = true;
    document.getElementById("C4").checked = true;
    document.getElementById("C1").checked = false;
    document.getElementById("C2").checked = false;
      }



    }


Male <input value="V1" checked="checked" name="R1" type="radio" onclick="select_radio('male')">
Female: <input name="R1" value="V2" type="radio" onclick="select_radio('female')">></p>
