<div id="parentID">
<div id="childOne">one</div>
<div id="childTwo">two</div>
<div id="childThree">three</div>
<div id="childFour">four</div>
<input type="button" id="btn" />
</div>比如说通过btn的click事件拿到childThree的值
<div id="childOne">one</div>
<div id="childTwo">two</div>
<div id="childThree">three</div>
<div id="childFour">four</div>
<input type="button" id="btn" />
</div>比如说通过btn的click事件拿到childThree的值
<div id="parentID">
<div id="childOne">one</div>
<div id="childTwo">two</div>
<div id="childThree">three</div>
<div id="childFour">four</div>
<input type="button" id="btn" onclick="shows(this);"/>
</div><script>
function shows(obj)
{
alert($(obj).parent().children().eq(2).text());
}
</script>
弱弱的问句:有id为什么不直接获取呢?
<div id="parentID">
<div id="childOne">one</div>
<div id="childTwo">two</div>
<div id="childThree">three</div>
<div id="childFour">four</div>
<input type="button" id="btn" />
</div>子元素$(function(){
$("#btn").click(function(){
var text = $(this).parent().children("#childThree").text();
alert(text);
var text1 = $(this).parent().children(":eq(2)").text();
alert(text1)
});
});
alert($(obj).parent().filter("#childThree"));
alert($(obj).parent().children("#childThree"));
alert($(obj).parent().find("#childThree"));
