jquery .attr()用法

Examples:
Example: Set some attributes for all <img>s in the page.

<!DOCTYPE html>
<html>
<head>
  <style>
  img { padding:10px; }
  div { color:red; font-size:24px; }
</style>
  <script src="http://code.jquery.com/jquery-latest.js"></script>
</head>
<body>
  
  <img />
  <img />
  <img />

  <div><B>Attribute of Ajax</B></div>

<script>
$("img").attr({ 
  src: "/images/hat.gif",
  title: "jQuery",
  alt: "jQuery Logo"
});
$("div").text($("img").attr("alt"));
</script>

</body>
</html>


给标签 添加元素

$('#greatphoto').attr('alt', 'Beijing Brush Seller');

删除元素
$("img").removeAttr("src");

得到元素值

$("img").attr("src");
