Get part of a string with JavaScript

Question

How might I figure out the category based on the CSS classes on the body please? Here is the body element:

<body class="archive category category-basketball category-23872 content-sidebar">

I want to output DFP page targeting for a category archive page. The format for the DFP page targeting code is

googletag.pubads().setTargeting( "category", "basketball" );

Therefore, I want to check for the existence of a category-{something} where {something} is the value for the category. Unfortunately, the 2nd category-23872 complicates the issue.

Appreciate any help and ideas. Thanks

Do you want to check for all category-FOOBAR where FOOBAR != integer? As pointed out by @DanielA.White regex should be doing that magic for you ;) — iLuvLogix

You can use regular expressions and match().

let str =  `<body class="archive category category-basketball category-23872 content-sidebar">`;
let res = str.match(/category-[^\s0-9]+/g)
console.log(res)
