如何在jquery中获取attr值

代码示例

jquery attr

$( some_item ).attr( "id", "some-id" );
// for setting multiple attributes, it's similar to the css() property. However, quotes are not always required for attr()
$( some_item ).attr({
  id: "some-id",
  // or others.
  title: "Opens in a new window",
  // attributes which contain dash(-), should be covered in quotes.
  "data-value": "internal link"
});

获取属性值jquery

var some_var = $( some_jquery_selector ).attr( 'some_attribute_name' );

jquery添加属性

$('#someid').attr('name', 'value');

jquery获取元素属性

<div data-role="page" data-last-value="43" data-hidden="true" data-options='{"name":"John"}'></div>
