I wanna get meta tags data using javascript(jquery) and regex.
Here are some meta tags.
<meta name="description" content="Amazon.com : Google Chromecast HDMI Streaming Media Player : Streaming Media Clients : Electronics" />
<meta name="title" content="Amazon.com : Google Chromecast HDMI Streaming Media Player : Streaming Media Clients : Electronics" />
I can get content from those forms using below function.
function getProductInfo(attr) {
var m = $("meta[name="+attr+"]");
var content = m.attr("content");
return content;
}
if(!title) var title = getProductInfo('title');
However sometimes there are different form of meta tags like
<meta property="title" content="....">
<meta property="og:title" content="....">
<meta name="title" description="....">
That's why I'm considering using regex. but I have no idea. please give me a tip. thanks.
Here's how you do it by not using RegEx
No libraries, pure vanilla JS:
var meta = document.querySelectorAll('meta');
for(var i=0;i<meta.length;i++){
var content = meta[i].getAttribute('content'); /* here's the content */
}
jQuery:
$('meta').each(function(index,tag){
var content = tag.getAttribute('content');
});
