How to get the content of the content attribute for a meta tag with js/jquery
Question
I'm trying to get the content of the content attribute of a meta tag on a webpage, I want my code to find all the metatags on a given webpage and I want the code to then read what's inside the content attribute and return that as a readable string. However, I don't want to specify any name or property attributes for the meta tag because I want the code to pick up all the content of all the meta tags.
I started like this:
var meta = $(document).find("meta[content]").text();
But this just returns an empty value, probably because it can't really find the content because I haven't specified it well. I'm new to this, please help me! :D
Thanks and may the force be with you!

类似于下面的代码来获取metatag内容
var author = $('meta[name=author]').attr("content");

The text() method returns the text content within an element. This is not correct when trying to retrieve information from a meta element, as they have no text.
instead, to retrieve the value of the content attribute, use attr() :
var content = $('meta[content]').attr('content');

The HTML is as below
<head>
<meta id="dirName" name="dirName" content="project name" />
</head>
The Jquery code will be
var dirPath= $('#dirName').attr('content');
console.log(dirPath);
