and i need to update the content of meta tag that has the name="description" using jQuery. How can i use the selectors to choose that content atribute of that tag?

推荐答案

$('meta[name=description]').attr('content', 'new value');

尽管这样做没有多大意义，因为使用此标记的网络抓取工具通常不支持javascript.

Although doing this doesn't make much sense because web crawlers which use this tag usually don't support javascript.
