嗨,我正在创建动态div元素,让我们说有4个div.DIV1,DIV2,DIV3,DIV4.每个div都有一组单选按钮rad1,rad2,rad3,rad4.见如下.
div1 ->rad1,rad2,rad3,rad4 groupName=rd1 ->end div1
div2 ->rad1,rad2,rad3,rad4 groupName=rd2 ->end div2
div3 ->rad1,rad2,rad3,rad4 groupName=rd3 ->end div3
div4 ->rad1,rad2,rad3,rad4 groupName=rd4 ->end div4
这是动态创建的html.我想从div2或div3中选择哪个收音机我必须写什么剧本？
function checkRadio() {
var radios = document.getElementById('rBox').getElementsByTagName('input');
for (var i = 0; i < radios.length; i++) {
radios[i].onclick = function(e) {
var pid = this.parentNode.id;
if ( pid == 'group-2' || pid == 'group-3' )
alert('PARENT: ' + this.parentNode.id )
}
}
}
<body onload="checkRadio()">
<div id="rBox">
<div class="rad" id="group-1">
<input type="radio" name="option" />
....
</div>
<div class="rad" id="group-2">
<input type="radio" name="option" />
....
</div>
....
</div>
</body>
