How to find if x equals any value in an array in javascript [duplicate]
You can use
if([a,b,c,d,e].includes(x)) { // ...}or
if([a,b,c,d,e].indexOf(x) !== -1) { // ...}
You can use the following code:
<script> var arr = [ 4, "Pete", 8, "John" ]; var $spans = $("span"); $spans.eq(0).text(jQuery.inArray("John", arr)); $spans.eq(1).text(jQuery.inArray(4, arr)); $spans.eq(2).text(jQuery.inArray("Karl", arr)); $spans.eq(3).text(jQuery.inArray("Pete", arr, 2));</script>Read this link for more information about it
