2组radio联动, 请教
现在碰到一个问题,有2组radio,选中其中一组的一个选项的时候,另外一组初始化为没有点击的状态。这个能实现么?
<input type="radio" name="fruit" value = "Apple">苹果<br>
<input type="radio" name="fruit" value = "Orange">桔子<br>
<input type="radio" name="vegetables" value = "Apple">黄瓜<br>
<input type="radio" name="vegetables" value = "Orange">番茄<br>
类似这样的,选中苹果后再选择番茄时,苹果的选中被取消
