weird string concat in JavaScript -
i got weird on string concat in jquery follow : var name = button.data('name') var emailname = button.data('email') var username = button.data('username') var userstatus = button.data('active') var userid = button.data('id') alert(userid) var actionupdate = "{{action('usercontroller@update', "+userid+")}}" alert(actionupdate) and result/alert userid 28723050-71e9-11e7-a0a9-e9f620359699 (uuid user id) when concated/joined, got actionupdate variable {{action('usercontroller@update', "userid")}} instead of {{action('usercontroller@update', "28723050-71e9-11e7-a0a9-e9f620359699")}} expected. i tried join string , variable concat or +=, didn't result expected. any alternatives , solution appreciated. if, odd reason, want {{action('usercontroller@update', "28723050-...9699")}} with single-quotes...
