我有这个工作：
<div data-people="australian">Australian people eats...</div>
<script type="text/javascript">
alert($("[data-people=australian]").html());
</script>
@H_403_4@但是这其他不行,我不知道如何解决：
<div id="mich">Australian people eats...</div>
<script type="text/javascript">
$("#mich").data("people","australian");
alert($("[data-people=australian]").html());
</script>
@H_403_4@为什么我无法从jQuery中设置数据 – * HTML5属性并使用它们来选择DOM对象？
@H_403_4@很感谢
解决方法
jQuery data()映射的数据属性是单向的.如果要在节点上实际设置属性,应该使用attr()函数.
$("#mich").attr("data-people","australian");
@H_403_4@从docs:
@H_301_20@
@H_403_4@The data- attributes are pulled in the first time the data property is accessed and then are no longer accessed or mutated (all data values are then stored internally in jQuery)
