Question

所以我实现了一种翻译我的网页内容的方法，只需按一下按钮就可以使用html data- *属性重新加载页面，在这种情况下我使用自定义数据属性data-en来存储div翻译的内容英语。

出于某种原因，我无法看到我的小代码不会影响容器的文本内容。

<script>
$('.settingswheel').click(function() {
var e = $('.settingsin');
var en = e.dataset.en;
alert(en);
e.text(en);

});
</script>

.postit {
  position:absolute; 
  overflow:hidden;
  left:1070px; 
  top:-155px; 
  padding-left:10px;

Answer 1

e是一个jQuery对象。 jQuery对象没有dataset属性

使用

var en = e[0].dataset.en;

或jQuery data()方法

var en = e.data('en);

$('.settingswheel').click(function() {
  var e = $('.settingsin');
  var en = e[0].dataset.en;
  // or
  //var en = e.data('en);
  alert(en);
  e.text(en);

});

Answer 2

e是一个jquery对象，您可以使用数据函数访问数据属性。

var en = e.data('en');

打印“设置”

无法使用html5数据属性更改div文本内容
