javascript syntax error

Question

I don’t understand the front-end, I encountered a small problem, no error was reported during use
But Adobe Dreamweaver CS6 prompted a syntax error

function sea(e,v) document.getElementById(e).value = v;

Answer 1

JS functions need to use {} to enclose the function body, as follows:

function sea(e,v) {document.getElementById(e).value = v;}

Answer 2

I guess you are missing the "{}" to wrap the function?
