Select value of property by using another property

Question

Let's say I have this:

<meta prop="foo" name="randomname1">
<meta prop="bar" name="randomname2">
<meta prop="foobar" name="randomname3">

And I want to get the value of name property but only for prop="bar". Order of the tags might not be always the same, so indexes are not a solution.

alert($('[prop=bar]').attr('name'))

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<meta prop="foo" name="randomname1">
<meta prop="bar" name="randomname2">
<meta prop="foobar" name="randomname3">

Use attr selector

Description: Selects elements that have the specified attribute with a value exactly equal to a certain value.

You can use attr() to get something attribute from your html element

try this:

var a = $('meta[prop="bar"]').attr('name');
console.log(a);
// 'randomname2'
