Question

在此表中，当我检查第1行的单选按钮（当前）时，当我再次检查第2行的当前内容时，第1行会自动取消选中。所有的无线电按钮都会被检查。这只是两个学生的样本。

Answer 1

设置名称并制作一组单选按钮，如

<div class='controls'>
  <input id='content' type='textbox' value='CSS SHAPES, SVG, CANVAS DESIGNS ROCK' />
  <select id='fontsize'>
    <option value='10'>10px</option>
    <option value='12'>12px</option>
    <option value='14'>14px</option>
    <option value='16' selected>16px</option>
  </select>
  <select id='fontname'>
    <option value='Arial' selected>Arial</option>
    <option value='Verdana'>Verdana</option>
    <option value='Courier'>Courier</option>
  </select>
  <button id='draw'>Draw</button>
</div>
<canvas id='canvas'></canvas>

和

() - name="rdg1" and id="Present"
() - name="rdg1" and id="Absent"

如果检查了rdg1 - Present并单击以检查rdg1 - 缺少复选框1将清除，与第二组相同。
