How can I do `$('meta[name=“csrf-token”]').attr('content')` in vanilla Javascript?

Question

I don't have jQuery and I want to know how can I do the same thing with vanilla javascript. Any help?

$('meta[name="csrf-token"]').attr('content')

Answer 1

document.querySelector('meta[name="csrf-token"]').getAttribute('content');

你就是这样做的。

Answer 2

meta elements actually have a content property , so you can simply write:

document.querySelector('meta[name=csrf-token]').content

Demo:

 console.log( document.querySelector('meta[name=csrf-token]').content ) 

 <meta name="csrf-token" content="example-content"/> 

Answer 3

您也可以使用getElementsByName

document.getElementsByName('csrf-token')[0].getAttribute('content')

Answer 4

使用querySelector()方法获取元素并使用getAttribute()方法从元素中获取属性值。

document.querySelector('meta[name="csrf-token"]').getAttribute('content')
